1N5348CE3/TR8

Overview

The Microchip Technology 1N5348CE3/TR8 is a silicon 5-watt Zener diode with an 11V nominal voltage and ±2% tolerance. It operates within a -65°C to +150°C range, featuring a maximum dynamic impedance of 2.5 ohms at 125mA test current. The device supports up to 8.0A regulator current and withstands 430A surge currents. Packaged in axial-lead epoxy meeting UL94V-0 standards, it offers RoHS compliance via the e3 suffix and tape-and-reel availability through the TR suffix.

Feature Summary

Provides precise voltage regulation with tight ±2% tolerance for stable circuit performance
Withstands high surge stresses and operates reliably across wide temperature ranges
Features flexible axial-lead mounting terminals suitable for various PCB configurations

Applications

Voltage regulation in power supply circuits
Overvoltage protection for sensitive electronic components
Reference voltage sources in measurement instrumentation

Procurement Notes

Verify that the specific part number includes both the C suffix for ±2% tolerance and the e3 suffix for RoHS compliance. Confirm the TR suffix indicates tape-and-reel packaging rather than bulk. Ensure the source document explicitly links these suffixes to the 1N5348 base model to avoid ordering incorrect tolerance or packaging variants.

Selection Notes

Select this component when strict voltage accuracy is required due to its ±2% tolerance specification. Consider the 5-watt power dissipation rating and thermal resistance characteristics for heat sinking requirements. Verify compatibility with existing axial-lead footprints and ensure the operating voltage aligns with the 11V nominal value for the intended application.

Part Context

This component belongs to the JEDEC registered 1N5333B through 1N5388B series of 5-watt Zener diodes manufactured by Microsemi's Scottsdale Division. The series covers voltages from 3.3V to 200V, offering various tolerance options including A, B, C, and D suffixes. The e3 designation indicates lead-free, RoHS-compliant construction using annealed matte-tin plating.
