1N5350AE3/TR12

Single Zener Diodes Overview

The Microchip Technology 1N5350AE3/TR12 is a silicon 5.0-watt Zener diode with a nominal voltage of 14 V and ±10% tolerance. It operates in the -65°C to +150°C range, featuring a T-18 axial lead package. The device includes RoHS compliance (e3 suffix) and tape-and-reel packaging (TR12 suffix). Key electrical parameters include a maximum reverse current of 75 µA at 10.1 V, a dynamic impedance of 2.5 Ω, and a maximum regulator current of 6.7 A.

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 applications

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 the component's JEDEC registration status and confirm that the e3 suffix indicates RoHS compliance while TR12 specifies tape-and-reel packaging. Ensure the supplier provides documentation confirming the specific ±10% voltage tolerance associated with the 'A' suffix. Cross-reference the manufacturer's discontinuation notices or PCNs to verify current production availability before finalizing procurement plans.

Single Zener Diodes Selection Notes

Select this component when a 5-watt power dissipation rating and a 14 V nominal breakdown voltage are required. The ±10% tolerance suits applications where tight voltage precision is not critical. Verify that the thermal resistance characteristics align with the system's heat sinking capabilities to maintain operation within the specified -65°C to +150°C junction temperature limits.

Single Zener Diodes Part Context

This part belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes manufactured by Microsemi (now Microchip Technology). The series offers a wide selection of voltages from 3.3 V to 200 V. The 1N5350 variant specifically targets the mid-range voltage segment within this robust axial-leaded family designed for general-purpose regulation.

Single Zener Diodes Replacement Considerations

Compatible substitutes within the same series include 1N5350B (±5% tolerance) and 1N5350C (±2% tolerance). Other manufacturers producing equivalent 5W axial Zener diodes may offer functional replacements, provided they match the 14 V nominal voltage and T-18 package dimensions.
