Performance Characteristics

Forward Voltage vs. Current

The HP5082 exhibits an exceptionally low forward voltage characteristic, making it ideal for low-voltage applications. The forward voltage remains stable across a wide temperature range, with minimal variation in typical operating conditions.

Reverse Recovery Characteristics

With recovery times measured in picoseconds, the HP5082 outperforms conventional PN junction diodes in high-speed applications. The absence of minority carrier storage effects enables clean switching transitions even at microwave frequencies.

Temperature Performance

The passivated construction provides excellent temperature stability, with forward voltage characteristics showing minimal drift across the military temperature range (-65°C to +125°C). Reverse leakage current remains well-controlled even at elevated temperatures.

Reliability Data

• MIL-STD-750 Test Method 1036: Passes 1000 temperature cycles (-65°C to +150°C)
• MIL-STD-750 Test Method 1021: Passes 1000 hours at 150°C operating life test
• Humidity Resistance: 85°C/85% RH for 1000 hours with no degradation
• Vibration Resistance: Meets MIL-STD-202 Method 204 vibration requirements

Handling and Mounting Considerations

ESD Sensitivity

While the HP5082 features passivated construction, proper ESD handling precautions should be observed during installation and handling. Use grounded workstations and wrist straps when working with these devices.

Soldering Recommendations

• Wave Soldering: 260°C maximum for 10 seconds
