Description
GPP20M is a general-purpose glass-passivated junction rectifier diode rated for 1000V reverse voltage and 2A average forward current. It is packaged in a DO-15 (DO-204AC) through-hole package and is designed for reliable rectification in power supplies and general electronic circuits, offering low leakage, good surge capability, and stable high-voltage performance.
Features
- Glass passivated junction for enhanced reliability
- Low forward voltage drop
- Low leakage current (typically < 0.1 µA)
- High surge current capability
- DO-15 (DO-204AC) axial package
- Complies with MIL-S-19500 environmental standards
- High-temperature soldering capability (275°C, 10s)
Functional Description
- Standard PN junction rectifier diode for converting AC to DC
- Conducts current in forward direction and blocks in reverse direction
- Glass passivation improves junction stability and reduces leakage
Design Notes
- Ensure adequate thermal dissipation for continuous 2A operation
- Use proper PCB spacing for high-voltage (1000V) applications
- Consider reverse recovery characteristics if used in high-frequency circuits
- Add snubber or RC damping in inductive load applications to reduce stress
- Check surge current rating for inrush-heavy applications (e.g., capacitive loads)
How to Choose This Part
- Select based on reverse voltage margin (≥1.5× system voltage recommended)
- Ensure forward current rating meets load requirements
- Consider switching speed for high-frequency applications (may require fast diode)
- Choose package based on thermal and mechanical constraints
Typical Applications
- AC to DC rectification (power supplies)
- Freewheeling diode in inductive circuits
- General-purpose rectifier in consumer and industrial electronics
- Bridge rectifier configurations
