1N5371B/TR12

Overview

The Microchip Technology 1N5371B/TR12 is a silicon Zener diode with a nominal voltage of 60 V and a tolerance of ±5%. It features a maximum power dissipation of 5.0 W at 25°C, a test current of 20 mA, and a maximum dynamic impedance of 40 Ω. The device operates within a temperature range of -65°C to +150°C and utilizes a T-18 axial lead package.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Withstands high surge stresses and exhibits minimal changes in voltage versus current
• Features flexible axial-lead mounting terminals for through-hole integration

Applications

• Voltage regulation circuits requiring 60 V reference
• Power supply protection against high surge stresses
• General purpose voltage clamping applications

Procurement Notes

Verify the specific suffix 'TR12' indicates tape and reel packaging per EIA-296 standards. Confirm RoHS compliance status as the base part number may differ from the e3 variant. Ensure the supplier provides official datasheets matching the JEDEC registered series specifications for accurate electrical validation.

Selection Notes

Select this component when a 60 V Zener voltage with ±5% tolerance is required. Consider the 5 W power rating and thermal resistance characteristics for heat sinking requirements. Verify that the T-18 package dimensions align with the target PCB layout constraints.

Part Context

This part belongs to the 1N5333B through 1N5388B series of JEDEC registered silicon Zener diodes. The series offers a wide selection of voltages from 3.3 V to 200 V. These plastic encapsulated devices are designed for high maximum DC currents with adequate heat sinking.

Replacement Considerations

Equivalent parts include other 60 V, 5 W Zener diodes in the T-18 package. Verify electrical parameters such as dynamic impedance and leakage current match the original design requirements before substitution.
