Overview
The Microchip Technology 1N5360/TR12 is a silicon 5-watt Zener diode from the JEDEC registered 1N5333-5388B series. It provides voltage regulation at a nominal Zener voltage of 25V with a tight tolerance of ±2%, indicated by the 'C' suffix in the base part number (1N5360C). The device operates within a temperature range of -65°C to +150°C and features a T-18 axial lead package. The '/TR12' suffix denotes availability in 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 circuits
- High power dissipation applications requiring adequate heat sinking
- Surge stress protection systems
Procurement Notes
Verify the specific ordering suffix against official documentation, as variations such as 'e3' indicate RoHS compliance while other prefixes may denote military screening levels like JAN or JANTX. Confirm that the tape and reel packaging aligns with automated assembly requirements and check for any discontinuance notifications regarding this specific variant.
Selection Notes
Select this component when a 25V regulation point with ±2% precision is required in a 5W power class. Ensure the design accommodates the thermal resistance characteristics, utilizing appropriate heat sinking to maintain junction temperatures within the specified limits during operation.
Part Context
This device belongs to the Microsemi Scottsdale Division's 1N5333B through 1N5388B series of silicon 5-watt Zener diodes. The series covers a wide voltage selection from 3.3V to 200V, offering various tolerance options identified by suffix letters on the part number.
Replacement Considerations
Consult official datasheets for equivalent parts within the 1N5333-5388B series or surface mount equivalents like SMBJ5333 to SMBJ5388B. Verify that substitute components match the required voltage, tolerance, and power dissipation ratings.
