1N5348A/TR12

Overview

The Microchip Technology 1N5348A/TR12 is a silicon 5.0-watt Zener diode with a nominal voltage of 11 V and ±10% tolerance. It operates in the -65°C to +150°C range, featuring a T-18 axial lead package. Electrical characteristics include a maximum dynamic impedance of 2.5 ohms at 125 mA test current, a maximum reverse leakage current of 5.0 µA at 8.0 V, and a maximum regulator current of 8.4 A.

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

Applications

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

Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm RoHS compliance status via the e3 suffix if required. Ensure proper handling procedures are followed during installation to maintain device integrity and performance reliability.

Selection Notes

Select this component when a 5-watt power rating and 11-volt regulation point are required. The T-18 package supports high thermal dissipation capabilities. Verify that the ±10% tolerance aligns with circuit design requirements for voltage accuracy and stability under varying load conditions.

Part Context

This part belongs to the JEDEC registered 1N5333B through 1N5388B series of axial-leaded 5.0-watt Zener diodes. The 'A' suffix indicates a standard ±10% voltage tolerance, while the 'TR12' suffix denotes tape and reel packaging options for automated assembly processes.

Replacement Considerations

Consult the official datasheet for equivalent parts within the 1N5333B-1N5388B series. Verify matching voltage ratings, power dissipation limits, and package dimensions before substituting.
