1EZ160D10/TR12

Overview

The Microsemi Corporation 1EZ160D10/TR12 is a single silicon Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 160 V with a tolerance of ±10%. The device has a maximum power dissipation rating of 1 W and utilizes a DO-204AL (DO-41) axial-leaded plastic package. It operates within a junction temperature range of -65°C to 150°C.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range.
• Features flexible axial-lead mounting terminals suitable for through-hole installation.
• Constructed with a plastic encapsulated body offering moisture classification Level 1.

Applications

• General-purpose voltage regulation circuits
• Power supply reference voltage generation
• Over-voltage protection in electronic systems

Procurement Notes

Verify the specific suffix 'TR12' indicates tape and reel packaging configuration. Confirm RoHS compliance status as standard commercial versions may differ from lead-free variants. Check manufacturer documentation for current lifecycle status, as this component series may be subject to discontinuation or replacement by newer equivalents.

Selection Notes

Select this component when a 160 V regulation point is required with moderate precision. Ensure the circuit design accommodates the 1 W power dissipation limit at expected operating temperatures. Verify that the axial lead form factor fits the target PCB layout constraints compared to surface mount alternatives.

Part Context

This part belongs to the 1EZ series of 1-watt Zener diodes manufactured by Microsemi. The series offers a wide selection of voltage values ranging from 3.3 V to 200 V. Different tolerance options are available via suffix codes, allowing designers to choose between standard 10% and tighter 5% or 2% specifications based on application requirements.

Replacement Considerations

Equivalent parts include other 160 V, 1 W Zener diodes in the DO-41 package. Verify electrical parameters such as impedance and leakage current match system requirements before substitution.
