Overview
The Microchip Technology 1N5353AE3/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 ±10% tolerance indicated by the 'A' suffix. The device operates within a temperature range of -65°C to +150°C and features an axial-lead T-18 package. The 'e3' suffix denotes RoHS compliance, while the 'TR13' suffix indicates tape and reel packaging per EIA-296 standards.
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
Applications
- Voltage regulation in power supply circuits
- Reference voltage sources for electronic systems
- Overvoltage protection components
Procurement Notes
Verify the component origin as the Microsemi Scottsdale Division, now part of Microchip Technology. Confirm that the 'e3' suffix ensures lead-free construction and the 'TR13' suffix specifies tape and reel packaging. Ensure the 'A' suffix matches the required ±10% voltage tolerance specification for the design.
Selection Notes
Select this component when a 5-watt power dissipation rating and a 16V Zener voltage are required. The axial-lead T-18 package is suitable for through-hole mounting. Consider the thermal resistance characteristics and derating curves if operating near maximum limits or in confined spaces without adequate heat sinking.
Part Context
This device belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes. The series offers a wide selection of voltages from 3.3V to 200V with various tolerance options identified by suffix letters. These plastic encapsulated diodes are designed for high DC currents with adequate heat sinking due to their low thermal resistance design.
Replacement Considerations
Surface mount equivalents are available in the SMBJ5333 to SMBJ5388B or SMBG5333B to SMBG5388B series. Other tolerance variants within the same series include B (±5%), C (±2%), and D (±1%) suffixes.
