Overview
The Microchip Technology 1N5369AE3/TR12 is a silicon 5.0-watt Zener diode with a nominal voltage of 51 V and ±10% tolerance. It operates within a temperature range of -65°C to +150°C, featuring a maximum reverse current of 0.5 µA at 38.8 V and a dynamic impedance of 27 Ω. The device utilizes an axial-lead T-18 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 changes versus current
- Features flexible axial-lead mounting terminals for versatile integration
Applications
- Voltage regulation circuits requiring robust thermal performance
- Power supply protection against high surge stresses
- Industrial equipment utilizing wide temperature operational ranges
Procurement Notes
Verify the component status as discontinued or obsolete through official manufacturer channels before procurement planning. Confirm that the TR suffix indicates tape-and-reel packaging compatible with automated assembly processes. Ensure compliance with RoHS standards by validating the e3 designation on the specific manufacturing lot documentation.
Selection Notes
Select this component when a 51 V reference is required with ±10% tolerance. Consider the 5 W power dissipation capability and low thermal resistance design for applications demanding high DC currents. Verify that the T-18 axial lead form factor aligns with the target printed circuit board layout constraints.
Part Context
This part belongs to the JEDEC registered 1N5333B through 1N5388B series of 5.0-watt Zener diodes. The series offers a wide voltage selection from 3.3 V to 200 V. The 'e3' suffix denotes RoHS compliance, while the 'TR' suffix specifies tape-and-reel packaging for automated handling.
Replacement Considerations
Consult official manufacturer documentation for confirmed substitute part numbers. Surface mount equivalents such as SMBJ5369A are available within the same product family.
