1N5375E3/TR13

Overview

The Microsemi Corporation 1N5375E3/TR13 is a silicon Zener diode from the 1N5333B-1N5388B series, designed for voltage regulation. It features an 82 V nominal Zener voltage with a ±5% tolerance and operates at a test current of 15 mA. The device dissipates up to 5.0 watts of power and exhibits a maximum dynamic impedance of 65 Ohms. Packaged in a T-18 axial lead configuration with void-free transfer molded epoxy, it supports a wide operating temperature range from -65°C to +150°C.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Withstands high surge stresses and offers minimal changes in voltage versus current
• Features flexible axial-lead mounting terminals suitable for various PCB layouts
• Constructed with a void-free thermosetting epoxy body meeting UL94V-0 standards

Applications

• Voltage regulation circuits requiring 5-watt power dissipation
• Power supply protection against transient overvoltages
• Reference voltage generation in industrial equipment

Procurement Notes

Verify that the part number includes the e3 suffix to confirm RoHS compliance and the TR suffix to ensure tape and reel packaging. Confirm the B suffix indicates the standard ±5% voltage tolerance. Ensure the component matches the specified T-18 axial package dimensions and thermal characteristics before integration into the design.

Selection Notes

Select this component when a 5-watt axial Zener diode is required for robust voltage clamping or regulation. The 82 V rating suits applications needing precise mid-range reference voltages. Consider the low thermal resistance design if high DC currents are expected with adequate heat sinking. Verify that the ±5% tolerance aligns with circuit requirements.

Part Context

This device belongs to the JEDEC registered 1N5333B through 1N5388B series of silicon 5-watt Zener diodes manufactured by Microsemi's Scottsdale Division. The series provides a wide selection of voltages from 3.3 V to 200 V. The 1N5375 variant specifically targets the 82 V segment within this extensive lineup of plastic encapsulated regulators.

Replacement Considerations

Surface mount equivalents such as SMBJ5375 or SMBG5375 are available from the same manufacturer. For military screening levels, prefixes MQ, MX, or MV may be added to the base part number.
