1N5930APE3/TR12

Single Zener Diodes Overview

The Microchip Technology 1N5930APE3/TR12 is a glass-encapsulated Zener diode with a nominal voltage of 16 V and a 10% tolerance. It operates in the DO-41 axial package, providing a steady-state power dissipation of 1.25 W at ambient temperature and 1.5 W rated average power. The device withstands junction temperatures from -65 °C to +175 °C, features a maximum dynamic impedance of 10 Ohms at a test current of 23.4 mA, and exhibits a reverse leakage current of 1 µA at 12.2 V.

Single Zener Diodes Feature Summary

• Hermetically sealed voidless hard glass construction with tungsten slugs for enhanced reliability and lower thermal resistance.
• Non-sensitive to electrostatic discharge per MIL-STD-750 method 1020.
• Inherently radiation hard as described in Microsemi MicroNote 050.

Single Zener Diodes Applications

• Voltage regulation over broad operating currents and temperatures
• High-reliability applications requiring hermetic sealing

Single Zener Diodes Procurement Notes

Verify the specific suffix 'TR12' against official documentation to confirm tape and reel packaging details, as standard nomenclature typically uses 'TR'. Confirm RoHS compliance status via the 'e3' designation if applicable to your supply chain requirements. Ensure the 10% tolerance level matches the design specifications for the target circuit application.

Single Zener Diodes Selection Notes

Select this component when a 16 V reference with 10% tolerance is required in an axial leaded package. Consider the high-temperature capability up to +175 °C and the radiation-hardened nature for demanding environments. Verify that the 1.25 W steady-state power dissipation meets the thermal management constraints of the host system.

Single Zener Diodes Part Context

This part belongs to the 1N5913BG–1N5956BG series of 1.5 W glass Zener diodes manufactured by Microchip Technology (formerly Microsemi). The series offers a wide voltage range from 3.3 V to 200 V with various tolerance options. These devices are designed for high-reliability applications and are available in multiple package styles including axial, MELF, and surface mount configurations.

Single Zener Diodes Replacement Considerations

Consult the manufacturer's datasheet for equivalent plastic-body constructions or alternative screening levels within the same JEDEC number series. Verify compatibility regarding package dimensions and electrical characteristics before substituting with other manufacturers' parts.
