1N5338B/TR12

Single Zener Diodes Overview

The Microsemi Corporation 1N5338B/TR12 is a silicon 5-watt Zener diode with a nominal voltage of 5.1 V and ±5% tolerance. It features a T-18 axial leaded package and operates within a temperature range of -65°C to +150°C. The device provides a maximum dynamic impedance of 1.5 Ohms at a test current of 240 mA, with a maximum reverse leakage current of 10 µA at 1.0 V. It withstands high surge stresses and offers minimal voltage change versus current.

Single Zener Diodes Feature Summary

Provides stable voltage regulation across a broad operating current and temperature range
Withstands high surge stresses and is nonsensitive to electrostatic discharge
Features flexible axial-lead mounting terminals for versatile installation

Single Zener Diodes Applications

Voltage regulation in power supply circuits
Overvoltage protection for sensitive electronic components
Reference voltage generation in measurement systems

Single Zener Diodes Procurement Notes

Verify the specific suffix 'TR12' indicates tape and reel packaging per EIA-296 standards. Confirm RoHS compliance status by checking for the 'e3' suffix, as standard versions may contain lead. Ensure the component meets MIL-PRF-19500 requirements if military screening is necessary, which requires specific prefix identifiers.

Single Zener Diodes Selection Notes

Select this component for applications requiring 5-watt power dissipation and precise 5.1 V regulation. Consider thermal resistance characteristics when designing heat sinking solutions. Verify that the axial lead configuration fits the mechanical constraints of the target PCB layout compared to surface mount alternatives.

Single Zener Diodes Part Context

This part belongs to the JEDEC registered 1N5333 through 1N5388B series of 5.0 watt Zener diodes. The series covers a wide voltage selection from 3.3 to 200 volts. The plastic encapsulated design ensures Level 1 moisture classification without requiring dry pack storage.
