Overview
The Microchip Technology 1N5354BE3/TR8 is a silicon 5-watt Zener diode with a nominal voltage of 17 V and a ±5% tolerance. It operates within a temperature range of -65°C to +150°C, featuring a maximum dynamic impedance of 2.5 Ohms at a test current of 70 mA. The device utilizes a T-18 axial lead package and is supplied in tape and reel format.
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 secure installation
Applications
- Voltage regulation circuits requiring robust thermal performance
- Power supply protection against high surge stresses
- Industrial equipment operating under extreme environmental conditions
Procurement Notes
Verify the component's RoHS compliance status and confirm the specific manufacturer origin, as sourcing data indicates potential discontinuation or restricted availability from certain distributors. Ensure the ordering suffix matches the required tape and reel packaging configuration before finalizing procurement orders.
Selection Notes
Select this component when a 5-watt power dissipation rating and a 17 V reference are required. Consider its wide operating temperature range and low dynamic impedance for applications demanding precise regulation under varying load currents and thermal stress conditions.
Part Context
This part belongs to the JEDEC registered 1N5333B through 1N5388B series of silicon Zener diodes manufactured by Microsemi (now Microchip Technology). The series offers a wide selection of voltages from 3.3 V to 200 V in a standardized plastic encapsulated axial-lead package designed for high-power applications.
Replacement Considerations
Consult official Microchip documentation for verified substitute part numbers. Cross-reference specifications such as power dissipation, voltage tolerance, and package dimensions to ensure functional compatibility.
