Overview
The Microchip Technology 1N5349BE3/TR12 is a silicon 5-watt Zener diode with a nominal voltage of 12 V and ±5% tolerance. It operates within a temperature range of -65°C to +150°C, featuring a maximum reverse leakage current of 2 µA at 8.6 V and a dynamic impedance of 2.5 Ohms. The component 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 change versus current
- Features flexible axial-lead mounting terminals for through-hole integration
Applications
- Voltage regulation circuits requiring 5-watt power dissipation
- High-current applications with adequate heat sinking
- Industrial and automotive environments demanding wide temperature stability
Procurement Notes
Verify the specific suffix configuration against official datasheets to confirm RoHS compliance and packaging type. Confirm availability status as distribution channels may list discontinued or limited stock items. Ensure thermal management requirements align with the specified junction-to-lead thermal resistance for reliable operation.
Selection Notes
Select this component for applications requiring precise 12 V regulation with tight ±5% tolerance. Consider the 5 W power rating and thermal characteristics when designing heat sinking solutions. Verify that the axial lead form factor fits the target PCB layout constraints.
Part Context
This part belongs to the JEDEC registered 1N5333B through 1N5388B series of silicon Zener diodes. Manufactured by Microsemi (now Microchip Technology), these devices are designed for robust performance in demanding electronic systems. The 'e3' suffix indicates lead-free construction compliant with environmental standards.
Replacement Considerations
Consult official manufacturer documentation for confirmed substitute part numbers. Cross-reference electrical parameters such as voltage, tolerance, and package dimensions before implementation.
