1N5353CE3/TR8

Overview

The Microchip Technology 1N5353CE3/TR8 is a silicon 5-watt Zener diode from the JEDEC registered 1N5333-5388B series. It provides voltage regulation at a nominal Zener voltage of 16 V with a tight tolerance of ±2%. 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 maximum dynamic impedance of 2.5 Ohms, a maximum reverse current of 75 µA, and a maximum regulator current of 6.0 A when adequately heat sunk.

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
• RoHS compliant construction available via specific ordering suffixes

Applications

• Voltage regulation circuits requiring high power dissipation
• Power supply protection against overvoltage conditions
• Reference voltage generation in industrial equipment

Procurement Notes

Verify the component manufacturer origin, as the datasheet originates from Microsemi Scottsdale Division. Confirm that the 'e3' suffix indicates RoHS compliance and the 'TR8' suffix specifies tape and reel packaging per EIA-296 standards. Ensure the part number matches the specific 16V variant within the 1N5333-5388B series before procurement.

Selection Notes

Select this component for applications requiring 5-watt power dissipation and precise voltage regulation. The ±2% tolerance (C suffix) suits designs needing tighter voltage control than standard B or A suffix devices. Consider thermal management requirements, as steady-state power depends on lead length and ambient temperature conditions defined in the derating curves.

Part Context

This component 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. The 1N5353 designation specifically identifies the 16 V variant within this family, distinguished by its unique test current and impedance values compared to adjacent series members.

Replacement Considerations

Substitutes must match the 16 V Zener voltage, 5 W power rating, and ±2% tolerance. Verify compatibility with the T-18 axial lead package and ensure the replacement device meets the same thermal resistance and surge current specifications.
