Overview
The Microchip Technology 1N5371E3/TR13 is a silicon 5-watt Zener diode from the JEDEC registered 1N5333-5388B series. It provides voltage regulation at a nominal Zener voltage of 60V with a ±5% tolerance, as indicated by the B suffix. The device operates within a temperature range of -65°C to +150°C and features a T-18 axial lead package. Electrical characteristics include a maximum dynamic impedance of 40 Ohms at a test current of 20mA, a maximum reverse leakage current of 0.5µA, and a maximum regulator current of 2.2A.
Feature Summary
- Provides stable voltage regulation across a broad operating current and temperature range
- Withstands high surge stresses and offers minimal changes in voltage versus current
- Features flexible axial-lead mounting terminals for standard through-hole integration
Applications
- Voltage regulation in power supply circuits
- Overvoltage protection for sensitive electronic components
- Reference voltage generation in measurement instrumentation
Procurement Notes
Verify the specific part number against official manufacturer documentation to confirm the presence of the e3 suffix for RoHS compliance and TR suffix for tape and reel packaging. Ensure that the procurement specifications align with the required voltage tolerance and thermal management capabilities defined in the datasheet before finalizing orders.
Selection Notes
Select this component when a 5-watt power dissipation rating and a 60V Zener voltage are required. Consider the ±5% tolerance and the specific dynamic impedance values if precise voltage regulation under varying load conditions is critical. Verify that the thermal resistance characteristics meet the heat sinking requirements of the target application environment.
Part Context
This component 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 selection from 3.3V to 200V. The 1N5371 variant specifically targets applications requiring a 60V regulation point within this standardized axial-leaded family.
Replacement Considerations
Surface mount equivalents such as SMBJ5371B or SMBG5371B are available within the same product family. These alternatives offer similar electrical performance but utilize different packaging formats suitable for surface mount technology processes.
