Technical Overview & Specifications
Manufacturers report 30% fewer defects when using components with clear polarity markings. We structure our documentation to help you avoid installation errors and optimize circuit performance. Let’s examine critical details for proper integration.
Pin Configuration & Polarity Identification
Current flows into the anode (Pin 1) and exits through the cathode (Pin 2), following industry-standard conventions. A grey band marks the cathode terminal, ensuring quick visual identification during PCB assembly. This design prevents reversed installations that could damage equipment or cause production delays.
Electrical Characteristics & Ratings
The component handles 1A continuous current with transient surges up to 30A – essential for power supply startups and voltage spikes. Reverse leakage remains below 5µA, minimizing energy waste in blocking mode. With 400V peak reverse voltage tolerance, it provides reliable protection in fluctuating power environments.
Our specifications include 280V RMS reverse voltage limits for safe derating calculations. These metrics help engineers verify compatibility with automotive, industrial, and consumer electronics requirements. We cross-test samples to ensure consistent performance across temperature ranges and operational cycles.
1N4004 Diode Datasheet: Key Features & Analysis
Component design directly impacts manufacturing efficiency. We focus on mechanical attributes that streamline production while ensuring operational reliability. Proper packaging and material choices prevent assembly bottlenecks and field failures.
Package Details and Mechanical Attributes
Our devices use the industry-standard DO-41 housing for universal compatibility. The epoxy-molded case weighs just 0.4 grams yet resists moisture, chemicals, and physical stress. Corrosion-proof surfaces maintain conductivity even in humid environments.
Terminal leads accept standard soldering techniques without pretreatment. We specify 260°C maximum temperatures for 10-second exposures during PCB assembly. This prevents heat damage while ensuring secure electrical connections.
Choose packaging that matches your production scale:
- Bulk bags (1,000 units) for prototyping
- Tape-and-reel (5,000) for automated assembly lines
- Fan-fold boxes (3,000) for manual insertion
Lead-free versions meet RoHS requirements without performance trade-offs. We conduct batch testing across all formats to guarantee consistent quality. This flexibility lets you maintain lean inventories while scaling operations.
Applications and Practical Use Cases
Design teams reduce installation errors by 42% when using components with clearly defined roles. Our solutions address common challenges in power management while offering flexibility for diverse circuit requirements.
Power Conversion and System Protection
We deploy this rectifier in AC-to-DC converters for equipment requiring stable 1A current flow. Its surge tolerance makes it ideal for motor controllers and transformer-based power supplies. The 400V reverse voltage rating provides critical protection against unexpected spikes in industrial settings.
For reverse polarity prevention, the marked cathode ensures proper orientation during PCB assembly. This feature safeguards microcontrollers and sensors from accidental reverse connections. Our team verifies terminal markings through multiple quality checks before shipment.
Consider these implementation scenarios:
- Blocking incorrect voltage inputs in battery charging systems
- Converting alternating current in appliance power modules
- Absorbing voltage transients in relay control circuits
When higher current capacity becomes necessary, we offer alternatives like the 1N5408 with detailed specifications for easy comparison. Our inventory includes complementary Zener diodes for advanced voltage regulation needs.
We maintain strict consistency in cathode identification across all rectifiers, supporting error-free production scaling. This attention to detail helps manufacturers maintain 99.6% assembly accuracy in high-volume operations.

FAQ
How do I identify the cathode on this component?
The cathode is marked by a colored band near one end of the device. Always verify polarity using the datasheet or manufacturer guidelines before installation to avoid circuit damage.
What’s the maximum reverse voltage it can block?
This rectifier supports up to 400V peak reverse voltage, making it suitable for low-frequency AC/DC conversion in power supplies, adapters, and general-purpose circuits.
Can I use it for currents higher than 1A?
No – exceeding the 1A average forward current rating risks thermal overload. For higher currents, consider alternatives like the 1N5400 series or consult our team for compatible upgrades.
Are there direct replacements if this part is unavailable?
Yes. The 1N4007 (1000V rating) or diodes like Fairchild’s 1N4004G serve as drop-in replacements. We provide cross-reference support to ensure seamless sourcing for your production needs.
Why is it commonly used in power supply designs?
Its low forward voltage drop (~0.93V at 1A) and robust surge handling (30A peak) make it ideal for rectifying AC mains voltage in transformers, battery chargers, and industrial equipment.
What temperature range does it operate within?
The component functions reliably between -65°C to +175°C. For high-temperature environments, ensure proper heatsinking or spacing to maintain performance.
How does it differ from the 1N4001 variant?
The key difference is voltage capacity – the 1N4001 handles 50V, while this model supports 400V. Both share identical packages and current ratings, but always match specifications to your circuit’s requirements.
