1N5344BE3/TR12

Single Zener Diodes Overview

The Microchip Technology 1N5344BE3/TR12 is a silicon 5.0-watt Zener diode from the JEDEC registered 1N5333B through 1N5388B series. It provides voltage regulation with a nominal Zener voltage of 8.2 V and a standard tolerance of ±5%. 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 maximum reverse current of 10 µA at 5.9 V, a dynamic impedance of 1.5 Ω, and a maximum regulator current of 5.7 A.

Single Zener Diodes 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 for secure installation
• Moisture classification is Level 1 per IPC/JEDEC J-STD-020B requiring no dry pack

Single Zener Diodes Applications

• Voltage regulation in power supply circuits
• Overvoltage protection for sensitive electronic components
• Reference voltage generation in measurement systems

Single Zener Diodes Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm RoHS compliance status via the e3 suffix designation. Ensure proper handling procedures are followed as the device is not ESD sensitive per MIL-STD-750 Method 1020. Validate packaging details match the TR suffix requirements for tape and reel delivery.

Single Zener Diodes Selection Notes

Select this component when a 5-watt power dissipation rating is required for high-current applications. The 8.2 V nominal voltage suits specific reference needs within the 3.3 V to 200 V selection range. Consider the T-18 package dimensions for board layout compatibility. Evaluate thermal resistance parameters to ensure adequate heat sinking for steady-state operation.

Single Zener Diodes Part Context

This part belongs to the 1N5333B through 1N5388B series of silicon Zener diodes manufactured by Microsemi (now Microchip Technology). The series covers voltages from 3.3 V to 200 V with various tolerance options identified by suffix letters. The e3 suffix indicates RoHS compliant devices with matte tin plating on the terminals.

Single Zener Diodes Replacement Considerations

Equivalent parts within the same series include 1N5343B and 1N5345B for slightly different voltage ratings. Verify mechanical fit and electrical parameters before substitution.
