1EZ160D/TR8

Overview

The Microsemi Corporation 1EZ160D/TR8 is a silicon Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 160V with a maximum power dissipation of 1W. The device utilizes a DO-204AL (DO-41) axial leaded package suitable for through-hole mounting. Key electrical characteristics include a reverse leakage current of 500nA at 121.6V and a forward voltage drop of 1.2V at 200mA. It operates within a temperature range of -65°C to +150°C.

Feature Summary

• Provides stable voltage regulation across broad operating current and temperature ranges
• Features flexible axial-lead mounting terminals for standard through-hole integration
• Constructed from silicon material for reliable unidirectional operation

Applications

• Voltage reference circuits requiring high-voltage stability
• Overvoltage protection in electronic systems
• General-purpose voltage regulation in industrial equipment

Procurement Notes

Verify the specific tolerance grade associated with the suffix D, as variations exist within the series. Confirm RoHS compliance status, as non-compliant variants are documented for similar part numbers. Check current availability status, as this component may be discontinued or subject to end-of-life notices. Ensure the DO-204AL package dimensions match the target PCB layout requirements before finalizing procurement.

Selection Notes

Select this component when a 160V Zener voltage is required with 1W power handling capability. Consider the ±10% tolerance typical for the 'D' suffix variant. Evaluate the thermal management needs given the 1W dissipation limit in the DO-41 package. Compare against higher power alternatives if circuit demands exceed 1W. Verify compatibility with the intended operating temperature range up to 150°C.

Part Context

This component belongs to the Microsemi 1EZ series of Zener diodes, which offers a wide selection of voltages ranging from 3.3V to 200V. The series is characterized by its robustness and non-sensitivity to electrostatic discharge per MIL-STD-750 method 1020. These diodes are commonly used in military and aerospace applications due to their reliability and wide voltage coverage.
