Overview
The Microchip Technology 1N5367CE3/TR13 is a silicon 5-watt Zener diode from the JEDEC registered 1N5333B-1N5388B series. It provides voltage regulation at a nominal Zener voltage of 43V with a tight tolerance of ±2%. The device features an axial lead DO-41 package and is supplied in tape and reel format. Key electrical characteristics include a maximum reverse current of 0.5 µA, a dynamic impedance of 20 ohms, and a maximum regulator current of 110 mA.
Feature Summary
- Provides stable voltage regulation across a broad operating current range
- Features low thermal resistance design for high DC current operation
- Offers flexible axial-lead mounting terminals
- Withstands high surge stresses
Applications
- Voltage regulation circuits
- Power supply protection
- Reference voltage generation
Procurement Notes
Verify the component matches the specific 43V Zener voltage and ±2% tolerance requirements. Confirm the e3 suffix indicates RoHS compliance and the TR13 suffix denotes tape and reel packaging. Ensure the supplier documentation aligns with the Microsemi/Microchip datasheet specifications for the 1N5367B series.
Selection Notes
Select this component for applications requiring 5-watt power dissipation and precise voltage regulation. The ±2% tolerance makes it suitable for circuits demanding tighter accuracy than standard ±5% or ±10% devices. Consider the axial lead form factor for through-hole mounting and verify heat sinking capabilities for steady-state operation.
Part Context
This part belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes manufactured by Microsemi (now Microchip Technology). The series covers a wide voltage range from 3.3V to 200V. The 'e3' suffix indicates RoHS compliance, while 'TR13' specifies the tape and reel packaging option.
Replacement Considerations
Compatible replacements within the same series include other 1N53xxB variants with different voltage ratings. For equivalent performance, ensure the substitute maintains the 5-watt power rating, axial DO-41 package, and ±2% tolerance if precision is required.
