1N5384C/TR12

Overview

The Microsemi 1N5384C/TR12 is a silicon 5-watt Zener diode with a nominal voltage of 160V and ±2% tolerance. It operates within a -65°C to +150°C range, featuring a void-free molded epoxy body and tin-plated axial leads. The device provides stable voltage regulation over broad current and temperature ranges, withstands high surge stresses, and exhibits minimal voltage change versus current. It is moisture classification Level 1 per IPC/JEDEC J-STD-020B.

Feature Summary

• Provides precise voltage regulation with tight ±2% tolerance
• Withstands high surge stresses and ESD events
• Operates reliably across wide temperature extremes
• Features flexible axial-lead mounting terminals

Applications

• Voltage regulation in power supplies
• Overvoltage protection circuits
• Reference voltage generation

Procurement Notes

Verify the specific suffix 'TR12' against official Microsemi documentation to confirm tape and reel packaging details. Ensure the C suffix corresponds to the required ±2% tolerance for your application. Confirm RoHS compliance status if environmental regulations apply. Cross-reference the part number with the latest datasheet revision to ensure all electrical parameters remain unchanged.

Selection Notes

Select this component when a 160V Zener diode with high precision is required. The 5W power rating allows for significant current handling with adequate heat sinking. Consider the thermal resistance characteristics and mounting method for derating calculations. Verify that the axial lead format fits the PCB layout constraints compared to surface mount alternatives.

Part Context

This part belongs to the JEDEC registered 1N5333 through 1N5388B series of 5-watt Zener diodes. The series covers voltages from 3.3V to 200V with various tolerance options. The 1N5384 variant specifically targets the 160V region, offering robust performance for industrial and commercial applications requiring reliable voltage clamping.

Replacement Considerations

Surface mount equivalents are available as SMBJ5384 or SMBG5384. Military screening levels can be obtained by adding MQ, MX, or MV prefixes. Standard tolerance versions include A (±10%), B (±5%), and D (±1%) suffixes.
