1N5384B/TR12

Overview

The Microsemi 1N5384B/TR12 is a silicon Zener diode with a nominal voltage of 160V and ±5% tolerance. It operates in an axial-lead T-18 package, dissipating up to 5W at 25°C. The device features a maximum reverse current of 0.5µA at 115V and a dynamic impedance of 350Ω. It withstands surge currents up to 1650A and maintains operation between -65°C and +150°C.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Withstands high surge stresses and exhibits minimal voltage change versus current
• Features flexible axial-lead mounting terminals for secure installation

Applications

• Voltage regulation in power supply circuits
• Overvoltage protection for sensitive electronic components
• Reference voltage generation in measurement systems

Procurement Notes

Verify the specific suffix configuration against official Microsemi documentation to confirm RoHS compliance status and screening level. Ensure the TR12 tape and reel packaging matches the required handling specifications for automated assembly processes before finalizing procurement orders.

Selection Notes

Select this component when a precise 160V regulation point is required within a 5W power dissipation envelope. Consider the thermal resistance characteristics and lead length requirements for adequate heat sinking. Verify that the ±5% tolerance aligns with the circuit's voltage stability constraints.

Part Context

This part belongs to the JEDEC registered 1N5333B through 1N5388B series of 5-watt Zener diodes. The series offers a wide voltage selection from 3.3V to 200V. The 'B' suffix indicates standard ±5% tolerance, while the 'TR12' suffix denotes tape and reel packaging options available for this family.

Replacement Considerations

Equivalent parts include other 160V 5W Zener diodes from manufacturers adhering to similar JEDEC standards. Verify pinout compatibility and thermal performance metrics before substitution.
