1N5383AE3/TR8

Overview

The Microsemi 1N5383AE3/TR8 is a silicon Zener diode with a nominal voltage of 150V and ±10% tolerance. It operates in a T-18 axial leaded package, dissipating up to 5W at 25°C. The device features a maximum reverse current of 0.5µA at 108V and a dynamic impedance of 330Ω at a test current of 8mA. It withstands surge currents up to 1500A 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 integration
• Non-sensitive to electrostatic discharge per MIL-STD-750 Method 1020

Applications

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

Procurement Notes

Verify the specific suffixes against official Microsemi documentation to confirm exact electrical tolerances and packaging configurations. Ensure the RoHS compliant e3 designation matches project requirements. Confirm that the TR8 tape and reel specification aligns with automated assembly equipment capabilities before finalizing procurement orders.

Selection Notes

Select this component when a 150V regulation point is required within the 1N5333-5388B series. Consider the ±10% tolerance and 5W power dissipation limits relative to thermal management constraints. Evaluate the axial lead form factor against available board space and mounting orientation requirements for the target application design.

Part Context

This part belongs to the JEDEC registered 1N5333B through 1N5388B series of 5-watt silicon Zener diodes manufactured by Microsemi's Scottsdale Division. The series offers a wide voltage selection from 3.3V to 200V with various tolerance options defined by suffix letters. These plastic encapsulated devices are designed for robust performance in demanding industrial environments.

Replacement Considerations

Equivalent parts include other manufacturers' 1N5383 variants meeting identical 150V/5W specifications. Verify mechanical dimensions and terminal plating compatibility when substituting. Cross-reference electrical parameters such as dynamic impedance and leakage current to ensure circuit performance remains within acceptable limits.
