1N5942APE3/TR8

Single Zener Diodes Overview

The Microchip Technology 1N5942APE3/TR8 is a glass-encapsulated Zener diode with a nominal voltage of 51 V and a ±10% tolerance. It operates in the DO-41 axial package, providing a maximum steady-state power dissipation of 1.5 W at a lead temperature of 85 °C or lower. The device features a junction-to-lead thermal resistance of 60 °C/W and supports a wide operating temperature range from -65 °C to +175 °C. Electrical characteristics include a maximum dynamic impedance of 70 Ohms at a test current of 7.3 mA, a knee current of 1.0 mA, and a maximum reverse leakage current of 1.0 µA at 1.0 V.

Single Zener Diodes Feature Summary

• Hermetically sealed voidless hard glass construction with tungsten slugs for enhanced reliability and radiation hardness.
• Flexible axial-lead mounting terminals compatible with through-hole assembly processes.
• Non-sensitive to electrostatic discharge (ESD) per MIL-STD-750 method 1020.
• Metallurgically enhanced internal contact design ensuring lower thermal resistance.

Single Zener Diodes Applications

• Voltage regulation across broad ranges of operating current and temperature.
• High-reliability applications requiring screening in reference to MIL-PRF-19500.
• Environments demanding inherent radiation hardness.

Single Zener Diodes Procurement Notes

Verify that the specific part number matches the required JEDEC type, tolerance level, and RoHS compliance status. Confirm the packaging suffix corresponds to tape and reel requirements. Ensure the procurement documentation aligns with the manufacturer's latest product change notices and environmental declarations.

Single Zener Diodes Selection Notes

Select this component when a 51 V Zener voltage with 10% tolerance is required in an axial package. Consider the 1.5 W power rating and the -65 °C to +175 °C operating temperature range for suitability in harsh environments. Evaluate the hermetic glass construction if radiation hardness or superior sealing is necessary compared to plastic alternatives.
