1N5371B

Overview

The Microsemi 1N5371B is a silicon Zener diode with a nominal voltage of 60V and a tolerance of ±5%. It operates in the 1N5333-5388B series, providing 5.0 watts of power dissipation at 25°C. The device features an axial lead T-18 plastic package and withstands a maximum surge current of 350A. Electrical characteristics include a test current of 20mA, a maximum dynamic impedance of 40 Ohms, and a maximum reverse current of 0.5μA.

Feature Summary

Provides stable voltage regulation across a broad operating current and temperature range
Withstands high surge stresses and maintains minimal voltage changes versus current
Features flexible axial-lead mounting terminals for versatile installation
Nonsensitive to electrostatic discharge (ESD) per MIL-STD-750 Method 1020

Applications

Voltage regulation circuits requiring stable DC references
Overvoltage protection for sensitive electronic components
High reliability applications utilizing military equivalent screening levels

Procurement Notes

Verify the specific suffix letter on the part number to confirm the exact voltage tolerance, as the B suffix indicates ±5% while other letters denote different tolerances. Confirm whether RoHS compliance is required by checking for the e3 suffix. Ensure adequate heat sinking is provided during operation to maintain performance within the specified thermal resistance limits.

Selection Notes

Select this component when a 60V reference with ±5% precision is needed in a through-hole configuration. Consider the 5W power rating and ensure sufficient thermal management is available. Verify that the axial lead form factor fits the mechanical constraints of the target PCB layout compared to surface mount alternatives.

Part Context

This device belongs to the JEDEC registered 1N5333-5388B series of 5.0 watt Zener diodes manufactured by Microsemi's Scottsdale Division. The series covers a wide voltage selection from 3.3V to 200V. These plastic encapsulated devices are designed for high maximum DC currents and offer various military equivalent screening options via prefix identifiers.
