1N5353C/TR8

Overview

The Microchip Technology 1N5353C/TR8 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 16 V with a tight tolerance of ±2%, indicated by the 'C' suffix. The device operates within a temperature range of -65°C to +150°C and features an axial lead T-18 package. Electrical characteristics include a maximum dynamic impedance of 2.5 Ohms and a maximum reverse current of 0.5 µA.

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 changes in voltage versus current
• Moisture classification is Level 1 per IPC/JEDEC J-STD-020B requiring no dry pack

Applications

• Voltage regulation circuits requiring precise tolerance
• Power supply protection against overvoltage conditions
• Reference voltage generation in electronic systems

Procurement Notes

Verify the manufacturer origin as the datasheet originates from Microsemi, which was acquired by Microchip Technology. Confirm that the TR8 suffix corresponds to the tape and reel packaging option specified in the mechanical data. Ensure the component meets the required RoHS compliance status if applicable to your assembly process.

Selection Notes

Select this component when a 16 V reference with ±2% precision is required in a 5 W power rating. Consider the thermal resistance of 25 °C/W junction-to-lead for heat sinking requirements. Verify that the axial T-18 package fits the PCB layout constraints and that the operating temperature range covers the environmental conditions.

Part Context

This part belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes. The series offers a wide selection of voltages from 3.3 V to 200 V. Different suffix letters identify specific voltage tolerances, with 'C' denoting ±2%. The series is JEDEC registered and available in various screening levels and packaging options.

Replacement Considerations

Equivalent parts within the same series include 1N5353B (±5% tolerance) or 1N5353D (±1% tolerance). Surface mount equivalents are available as SMBJ5353 or SMBG5353B.
