1N5353C/TR12

Overview

The Microchip Technology 1N5353C/TR12 is a silicon 5-watt Zener diode with a nominal voltage of 16 V and a ±2% tolerance. It operates within a temperature range of -65°C to +150°C, featuring a maximum reverse current of 1.0 µA at 11.5 V and a dynamic impedance of 2.5 Ω at a test current of 75 mA. The device utilizes a T-18 axial lead package and is supplied in tape and reel format.

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 integration

Applications

• Voltage regulation circuits requiring high power dissipation
• High current applications with adequate heat sinking
• Surge protection environments

Procurement Notes

Verify the component's JEDEC registration status and confirm RoHS compliance details before procurement. Ensure that the specific C suffix designation matches the required ±2% voltage tolerance for your design specifications. Cross-reference the TR12 packaging configuration with your automated assembly equipment requirements to ensure compatibility.

Selection Notes

Select this component when a 5-watt power rating and tight ±2% voltage tolerance are necessary. Consider the thermal resistance characteristics and derating curves if operating near maximum limits. Verify that the T-18 package dimensions fit the available board space and that the axial leads align with the intended mounting orientation.

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 covers a wide voltage selection from 3.3V to 200V, utilizing plastic encapsulated bodies with moisture classification Level 1. The 'C' suffix specifically denotes the tighter ±2% tolerance variant within this family.

Replacement Considerations

Equivalent parts include other 16V 5W Zener diodes with ±2% tolerance in T-18 packages. Verify electrical parameters such as dynamic impedance and reverse leakage current against the original datasheet specifications to ensure functional compatibility.
