1N5350AE3/TR8

Overview

The Microchip Technology 1N5350AE3/TR8 is a silicon Zener diode with a nominal voltage of 13V and a tolerance of ±10%. It features a maximum power dissipation of 5.0 watts at 25°C, operating within a temperature range of -65°C to +150°C. The device utilizes an axial-lead T-18 package and includes the e3 suffix for RoHS compliance and TR8 for tape-and-reel packaging.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features flexible axial-lead mounting terminals suitable for through-hole applications
• Withstands high surge stresses and exhibits minimal changes in voltage versus current
• Moisture classification is Level 1 per IPC/JEDEC J-STD-020B requiring no dry pack

Applications

• Voltage regulation in power supply circuits
• Reference voltage sources for analog circuits
• Overvoltage protection components
• General-purpose clipping and clamping applications

Procurement Notes

Verify that the ordering suffix matches the required specifications: 'A' indicates ±10% voltage tolerance, 'e3' confirms lead-free/RoHS compliance, and 'TR8' specifies the tape-and-reel packaging format. Confirm the manufacturer origin as Microsemi or Microchip Technology to ensure authenticity and adherence to JEDEC registration standards.

Selection Notes

Select this component when a 13V Zener reference with ±10% tolerance is required. Ensure adequate heat sinking is provided to maintain operation below the maximum thermal limits. Verify that the circuit design accommodates the specified dynamic impedance and reverse leakage current characteristics for the intended application environment.

Part Context

This part belongs to the 1N5333B through 1N5388B series of JEDEC registered silicon 5-watt Zener diodes. The series offers a wide selection of voltages from 3.3V to 200V. The specific model integrates standard plastic encapsulation with isolated case connections and void-free transfer molded epoxy bodies meeting UL94V-0 flammability ratings.

Replacement Considerations

Equivalent parts include other 1N5350 variants with matching voltage and power ratings. Cross-reference with SMBJ5350AE3 for surface mount requirements. Verify that any substitute maintains the same axial lead configuration and thermal resistance characteristics.
