Overview
The Microchip Technology 1N5360BE3/TR12 is a silicon 5-watt Zener diode from the JEDEC registered 1N5333B to 1N5388B series. It provides voltage regulation at a nominal Zener voltage of 25V with a standard tolerance of ±5%. 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 4.0 Ohms, a maximum reverse current of 0.5 µA, and a maximum regulator current of 4.3 A.
Feature Summary
- Provides stable voltage regulation across a broad operating current and temperature range
- Withstands high surge stresses and withstands steady-state power dissipation up to 5 watts
- Features flexible axial-lead mounting terminals for through-hole applications
- RoHS compliant construction available via the e3 suffix
Applications
- Voltage regulation in power supply circuits
- Overvoltage protection for sensitive electronic components
- Reference voltage generation in measurement equipment
Procurement Notes
Verify the specific part number against official manufacturer documentation to confirm RoHS compliance status associated with the e3 suffix. Ensure the TR12 tape and reel packaging matches the required manufacturing process. Confirm that the component meets all applicable environmental and export control classifications before finalizing procurement orders.
Selection Notes
Select this component when a 5-watt power rating and a 25-volt regulation point are required. The B suffix indicates a standard ±5% voltage tolerance suitable for general-purpose applications. Consider thermal derating curves if ambient temperatures exceed 25°C or if heat sinking is not utilized on a printed circuit board.
Part Context
This component belongs to the 1N5333B through 1N5388B series of silicon Zener diodes manufactured by Microsemi (now Microchip Technology). The series offers a wide selection of voltages ranging from 3.3V to 200V in a robust plastic encapsulated axial-lead case designed for high-power dissipation and reliable operation in demanding environments.
Replacement Considerations
Surface mount equivalents such as SMBJ5360B or SMBG5360B are available from the same manufacturer family. Verify pinout compatibility and thermal performance differences when transitioning between axial leaded and surface mount packages.
