1N5350A/TR12

Single Zener Diodes Overview

The Microchip Technology 1N5350A/TR12 is a silicon 5.0-watt Zener diode from the JEDEC registered 1N5333-5388B series, manufactured by the Microsemi Scottsdale Division. It provides voltage regulation at a nominal Zener voltage of 13 V with a ±10% tolerance. The device operates within a temperature range of -65°C to +150°C and features an axial-lead T-18 package. The 'TR' suffix indicates tape and reel packaging per EIA-296 standards.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features flexible axial-lead mounting terminals for through-hole applications
• Withstands high surge stresses and exhibits minimal voltage change versus current
• Moisture classification Level 1 requiring no dry pack storage

Single Zener Diodes Applications

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

Single Zener Diodes Procurement Notes

Verify component authenticity and datasheet revision status prior to procurement. Confirm that the specific ordering suffix matches the required packaging configuration. Ensure compatibility with existing thermal management designs given the 5-watt power dissipation rating. Check for any applicable military screening prefixes if higher reliability levels are required for the intended application environment.

Single Zener Diodes Selection Notes

Select this component when a 13 V regulation point with ±10% tolerance is required. Consider the T-18 axial lead package for through-hole mounting constraints. Evaluate thermal resistance requirements based on the specific heat sinking method, as steady-state power dissipation varies significantly between free-air and FR4 PC board mounting conditions.

Single Zener Diodes Part Context

This part belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes originally produced by Microsemi's Scottsdale Division. The series covers a wide voltage selection from 3.3 V to 200 V. Different suffix letters identify specific voltage tolerances, with the 'A' suffix denoting ±10% tolerance. The series is JEDEC registered and available in various screening levels.

Single Zener Diodes Replacement Considerations

Equivalent parts include other 5-watt Zener diodes with a 13 V nominal voltage and ±10% tolerance in a T-18 package. Verify pinout compatibility and thermal characteristics before substitution.
