Overview
The Microchip Technology 1N5372BE3/TR13 is a silicon 5-watt Zener diode with a nominal voltage of 62 V and a ±5% tolerance. It operates within a temperature range of -65°C to +150°C, featuring a maximum reverse leakage current of 500 nA at 44.6 V and a dynamic impedance of 42 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 changes versus current
- Features flexible axial-lead mounting terminals for secure installation
Applications
- Voltage regulation in power supply circuits
- Overvoltage protection for sensitive electronic components
- Reference voltage generation in measurement systems
Procurement Notes
Verify the manufacturer origin, as the datasheet identifies Microsemi while the model suffix indicates Microchip Technology. Confirm RoHS compliance status via the e3 suffix and ensure the TR13 designation matches the required tape and reel packaging specifications for automated assembly processes.
Selection Notes
Select this component when a 62 V regulation point is required with a 5 W power dissipation capacity. Ensure the application allows for adequate heat sinking to maintain performance within the specified thermal resistance limits. Verify that the axial lead configuration fits the mechanical constraints of the target PCB layout.
Part Context
This device belongs to the JEDEC registered 1N5333B through 1N5388B series of 5-watt Zener diodes. The series offers a wide selection of voltages from 3.3 V to 200 V. The B suffix specifically denotes a standard voltage tolerance of plus or minus 5%, distinguishing it from tighter tolerance variants like C or D suffixes.
Replacement Considerations
Surface mount equivalents are available as SMBJ5372B or SMBG5372B. Other manufacturers may offer generic 1N5372 replacements, but electrical parameters such as dynamic impedance and leakage current should be verified against the original datasheet requirements.
