1N5364AE3/TR12

Overview

The Microchip Technology 1N5364AE3/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 33 V with a ±10% tolerance, indicated by the 'A' suffix. The device operates in a T-18 axial lead package and features a maximum reverse current of 0.5 µA at 23.8 V. Electrical characteristics include a test current of 40 mA, a maximum dynamic impedance of 10 Ω, and a maximum regulator current of 3.5 A. It withstands surge currents up to 150 A and maintains operation within a temperature range of -65°C to +150°C.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Withstands high surge stresses and exhibits minimal changes in voltage versus current
• Features flexible axial-lead mounting terminals for through-hole integration
• Moisture classification is Level 1 per IPC/JEDEC J-STD-020B requiring no dry pack

Applications

• Voltage reference circuits
• Overvoltage protection systems
• Power supply regulation

Procurement Notes

Verify the component origin as this part was originally manufactured by Microsemi before its acquisition by Microchip Technology. Confirm that the specific ordering suffix matches the required tape and reel packaging format. Ensure the RoHS compliant status aligns with project environmental requirements. Check for any discontinuance notifications or lifecycle status updates relevant to long-term production plans.

Selection Notes

Select this component when a 5-watt power dissipation rating and a 33 V nominal breakdown voltage are required. The ±10% tolerance suits applications where tight precision is not critical. Consider the T-18 package dimensions and thermal resistance characteristics for adequate heat sinking. Verify that the maximum regulator current and surge current capabilities meet the circuit's peak load demands.

Part Context

This device belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes. The series offers a wide selection of voltages ranging from 3.3 V to 200 V. Different tolerance levels are available via specific suffix letters, such as B for ±5% and A for ±10%. The components are plastic encapsulated with void-free transfer molded thermosetting epoxy bodies meeting UL94V-0 standards.
