1N5352E3/TR12

Overview

The Microchip Technology 1N5352E3/TR12 is a silicon 5.0-watt Zener diode from the JEDEC registered 1N5333-5388B series, manufactured by the Microsemi Scottsdale Division. It provides voltage regulation at a nominal Zener voltage of 15V with a standard tolerance of ±5%. The device features an axial-lead T-18 package and operates within a temperature range of -65°C to +150°C. Electrical characteristics include a maximum reverse current of 75 µA and a dynamic impedance of 2.5 Ohms. The 'e3' suffix indicates RoHS compliance, while the 'TR12' suffix designates tape and reel packaging.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features flexible axial-lead mounting terminals for through-hole applications
• Withstands high surge stresses and exhibits minimal voltage change versus current
• Moisture classification is Level 1 per IPC/JEDEC J-STD-020B without requiring dry pack

Applications

• Voltage regulation in power supply circuits
• Reference voltage sources for electronic systems
• Overvoltage protection components

Procurement Notes

Verify that the component matches the specific 1N5352E3 variant with the TR12 tape and reel suffix. Confirm the manufacturer origin as Microsemi or its successor entity Microchip Technology. Ensure the datasheet revision aligns with the required specifications for your application. Check for any discontinuance notifications or product change notices affecting availability.

Selection Notes

Select this component when a 15V Zener voltage with ±5% tolerance is required for 5-watt power dissipation. Consider the T-18 axial lead package for through-hole mounting requirements. Evaluate thermal management needs based on the specified junction-to-lead thermal resistance. Verify that the operating environment falls within the -65°C to +150°C temperature range.

Part Context

This part belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes. The series covers a wide voltage selection from 3.3V to 200V. Different tolerance levels are identified by suffix letters such as B for ±5%, A for ±10%, C for ±2%, and D for ±1%. The e3 suffix denotes RoHS compliant devices available from the manufacturer.

Replacement Considerations

Consult the official datasheet for equivalent parts within the same series. Other variants like 1N5352B or 1N5352C may be considered if voltage tolerances differ. Verify mechanical compatibility with the T-18 package dimensions before substitution.
