1N5360E3/TR12

Single Zener Diodes Overview

The Microchip Technology 1N5360E3/TR12 is a silicon 5-watt Zener diode from the JEDEC registered 1N5333-5388B series. It provides voltage regulation at a nominal Zener voltage of 25 V with a ±5% tolerance, indicated by the B suffix. The device operates within a temperature range of -65°C to +150°C and features a T-18 axial lead package. Electrical characteristics include a test current of 50 mA, a maximum dynamic impedance of 4.0 Ohms, and a maximum reverse leakage current of 0.5 µA. The component is RoHS compliant and available in tape and reel packaging.

Single Zener Diodes 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 through-hole applications
• Moisture classification Level 1 requiring no dry pack storage

Single Zener Diodes Applications

• Voltage regulation circuits
• Surge protection systems
• Reference voltage sources

Single Zener Diodes Procurement Notes

Verify the specific suffix letter (e.g., B) to confirm the voltage tolerance matches design requirements. Confirm that the TR12 designation corresponds to the tape and reel packaging option as specified in the datasheet. Ensure the manufacturer origin aligns with project specifications, noting historical production by Microsemi Scottsdale Division under Microchip Technology.

Single Zener Diodes Selection Notes

Select this component when a 5-watt power dissipation rating and a 25 V regulated output are required. The T-18 plastic encapsulated case supports operation up to +150°C junction temperature. Verify thermal resistance requirements against the derating curve if mounted on an FR4 PC board rather than using direct lead heat sinking.

Single Zener Diodes Part Context

This part belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes. The series covers a voltage selection from 3.3 V to 200 V. Different suffix letters identify specific voltage tolerances, with the B suffix denoting ±5%. The e3 suffix indicates RoHS compliance, while the TR suffix denotes tape and reel packaging availability.
