1N5340E3/TR12

Single Zener Diodes Overview

The Microchip Technology 1N5340E3/TR12 is a silicon 5-watt Zener diode with a nominal voltage of 6.0 V and a ±5% tolerance. It operates within a temperature range of -65°C to +150°C, featuring a maximum reverse current of 1.0 µA at 3.0 V and a dynamic impedance of 1.0 Ω. The device utilizes an axial-lead T-18 package and is supplied in tape and reel format.

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 integration

Single Zener Diodes Applications

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

Single Zener Diodes Procurement Notes

Verify the component origin as this part was originally manufactured by Microsemi, now part of Microchip Technology. Confirm RoHS compliance via the e3 suffix and ensure the TR12 designation matches the required tape and reel packaging specifications for your assembly process.

Single Zener Diodes Selection Notes

Select this component when a 6.0 V reference with ±5% precision is required in a 5-watt axial package. Ensure adequate heat sinking is provided if operating near the maximum steady-state power limit or in elevated ambient temperatures to maintain reliability.

Single Zener Diodes Part Context

This device belongs to the JEDEC registered 1N5333B through 1N5388B series of silicon Zener diodes. The series offers a wide selection of voltages from 3.3V to 200V in a robust plastic encapsulated T-18 case suitable for high-power applications.

Single Zener Diodes Replacement Considerations

Compatible equivalents include the MX1N5340B (Microsemi) and standard 1N5340B variants. Verify that replacement parts match the specific B suffix tolerance and e3 RoHS compliance requirements.
