1N5348A/TR8

Overview

The Microchip Technology 1N5348A/TR8 is a silicon 5-watt Zener diode with a nominal voltage of 11 volts and a ±10% tolerance. It operates within a temperature range of -65°C to +150°C and features an axial-lead T-18 package. The device includes a TR suffix indicating tape and reel packaging per EIA-296 standards.

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

Applications

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

Procurement Notes

Verify the specific manufacturer origin, as this part number originates from the Microsemi Scottsdale Division which has undergone corporate restructuring. Confirm that the 'TR' suffix correctly denotes the required tape and reel packaging format for your automated assembly process before finalizing procurement orders.

Selection Notes

Select this component when a 5-watt power dissipation rating and an 11-volt regulation point are required. Ensure the design accommodates the thermal resistance characteristics and verify that the ±10% voltage tolerance meets the circuit specifications compared to tighter tolerance alternatives.

Part Context

This component belongs to the JEDEC registered 1N5333B through 1N5388B series of axial-leaded 5.0 watt Zener diodes. The series covers a voltage selection from 3.3 to 200 volts, utilizing specific suffix letters to identify different voltage tolerances such as A, B, C, or D.

Replacement Considerations

Consult official datasheets for cross-reference data regarding equivalent parts from other manufacturers. Verify mechanical dimensions and electrical parameters match before substituting.
