Overview
The Microchip Technology 1N5354BE3/TR13 is a silicon 5-watt Zener diode from the JEDEC registered 1N5333B to 1N5388B series. It provides voltage regulation with a nominal Zener voltage of 17 V and a standard tolerance of ±5%. The device features an axial-lead T-18-2 package, operates within a temperature range of -65°C to +150°C, and includes RoHS-compliant annealed matte-tin plating.
Feature Summary
- Provides stable voltage regulation across a broad operating current and temperature range
- Withstands high surge stresses and offers minimal changes in voltage versus current
- Features flexible axial-lead mounting terminals for versatile integration
Applications
- Voltage regulation circuits requiring 5-watt power dissipation
- Power supply protection against transient overvoltages
- Reference voltage generation in electronic systems
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm packaging and compliance details. Confirm that the TR13 designation aligns with the required tape and reel specifications. Ensure compatibility with existing thermal management designs given the 5-watt power rating and junction-to-lead thermal resistance characteristics.
Selection Notes
Select this component when a robust 5-watt axial Zener diode is required for high-power applications. The 17 V nominal voltage and ±5% tolerance suit precise regulation needs. Consider the wide operating temperature range and low thermal resistance for environments demanding reliable performance under varying thermal conditions.
Part Context
This part belongs to the Microsemi (now Microchip Technology) Scottsdale Division 1N5333B through 1N5388B series. These are plastic-encapsulated, JEDEC-registered silicon Zener diodes designed for general-purpose voltage regulation. The series offers a wide selection of voltages from 3.3V to 200V with various tolerance options.
Replacement Considerations
Direct replacements include other 1N5354B variants from different manufacturers meeting the same JEDEC registration. Surface mount equivalents such as SMBJ5354B or SMBG5354B may be considered if board space constraints require a change in package type, though thermal performance will differ.
