1N5388/TR8

Overview

The Microsemi Corporation 1N5388/TR8 is a silicon 5.0-watt Zener diode from the JEDEC registered 1N5333-5388B series, designed for voltage regulation applications. It features a nominal Zener voltage of 200 V with a standard ±20% tolerance. The device operates within an ambient temperature range of -65°C to +150°C and utilizes a T-18 axial leaded plastic package. Electrical characteristics include a maximum reverse leakage current of 500 nA at 144 V and a maximum dynamic impedance of 480 Ohms.

Feature Summary

Provides stable voltage regulation across broad operating current and temperature ranges
Withstands high surge stresses and exhibits minimal changes in voltage versus current
Features flexible axial-lead mounting terminals suitable for through-hole integration
Non-sensitive to electrostatic discharge (ESD) per MIL-STD-750 Method 1020

Applications

Voltage regulation circuits requiring high power dissipation capabilities
Surge protection systems utilizing high specified maximum current ratings
Industrial equipment operating under extreme thermal conditions

Procurement Notes

Verify component authenticity by checking manufacturer markings against datasheet specifications. Confirm the presence of the TR suffix indicates tape and reel packaging compliant with EIA-296 standards. Ensure procurement channels provide valid traceability documentation for this discontinued product line.

Selection Notes

Select this component when a 200 V Zener voltage with ±20% tolerance is required. Consider the 5 W power dissipation rating and low thermal resistance design for heat sinking requirements. Verify that the T-18 axial lead package fits the target PCB layout constraints.

Part Context

This part belongs to the 1N5333-5388B series of silicon 5-watt Zener diodes manufactured by Microsemi's Scottsdale Division. The series offers a wide selection of voltages from 3.3 V to 200 V with various tolerance options identified by specific suffix letters on the part number.
