1N5353E3/TR13

Overview

The Microchip Technology 1N5353E3/TR13 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 16V with a ±5% tolerance (B suffix). The device operates within a temperature range of -65°C to +150°C and features a T-18 axial-lead package. Electrical characteristics include a test current of 75mA, maximum dynamic impedance of 2.5 Ohms, and maximum reverse current of 0.5µA.

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
• Moisture classification Level 1 requiring no dry pack storage

Applications

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

Procurement Notes

Verify that the component matches the specific 16V Zener voltage and B suffix tolerance requirements. Confirm the e3 suffix indicates RoHS compliance and the TR suffix denotes tape and reel packaging. Ensure the supplier source aligns with Microchip or authorized distribution channels for this discontinued Microsemi product line.

Selection Notes

Select this component when a 5-watt power dissipation rating is required for high-current regulation tasks. Consider the T-18 package dimensions for board layout constraints. Evaluate thermal management needs, as steady-state power dissipation depends on lead length or PCB copper pad area. Verify compatibility with existing circuit designs utilizing the 1N5333-5388B series.

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 offers a wide selection of voltages from 3.3V to 200V with various tolerance options. The 1N5353 variant specifically targets the 16V regulation point within this extensive lineup.

Replacement Considerations

Surface mount equivalents are available as SMBJ5353B or SMBG5353B. Military screening levels can be obtained using MQ, MX, or MV prefixes. Other voltage variants within the 1N5333-5388B series may serve as functional substitutes if voltage ratings differ.
