1EZ160D/TR12

Overview

The Microsemi Corporation 1EZ160D/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 ±20%. The device is rated for a maximum power dissipation of 1 W and operates within a junction temperature range of -65°C to +150°C. It utilizes the DO-204AL (DO-41) axial leaded plastic package, providing flexible mounting terminals suitable for through-hole assembly.

Feature Summary

• Provides stable voltage regulation at 160 V with standard tolerance
• Capable of handling high surge stresses during operation
• Features moisture classification Level 1 requiring no dry pack storage

Applications

• General purpose voltage regulation circuits
• Protection against overvoltage transients
• Reference voltage sources in electronic systems

Procurement Notes

Verify component authenticity by checking manufacturer markings and datasheet alignment. Confirm RoHS compliance status as specific suffixes may vary. Ensure proper handling procedures are followed despite Level 1 moisture sensitivity. Validate that the axial lead configuration matches the target PCB footprint requirements before finalizing procurement orders.

Selection Notes

Select this component when a 160 V Zener reference is required in an axial package. Consider the ±20% tolerance if precise voltage clamping is not critical. Evaluate thermal management needs given the 1 W power rating. Compare against tighter tolerance variants like the 1EZ160D2 series if higher accuracy is necessary for the specific application design.

Part Context

This part belongs to the 1EZ series of axial-leaded Zener diodes from Microsemi. The series offers various voltage selections ranging from 110 to 200 volts in the DO-41 package. Different suffixes indicate varying tolerance levels, allowing designers to choose between standard and tighter specifications based on circuit precision requirements.

Replacement Considerations

Check for equivalent parts from other manufacturers offering 160 V, 1 W, DO-41 packages. Verify pinout compatibility and thermal characteristics. Note that the 1EZ160D2E3TR is a similar variant with tighter 2% tolerance.
