1N5372BE3/TR12

Overview

The Microchip Technology 1N5372BE3/TR12 is a silicon 5.0-watt Zener diode from the JEDEC registered 1N5333B-1N5388B series, manufactured by Microsemi. It provides voltage regulation at a nominal Zener voltage of 62 V with a standard tolerance of ±5%. The device operates within a temperature range of -65°C to +150°C and features a maximum reverse current of 500 nA. Packaged in an axial T-18 leaded format, it includes a tape and reel option for automated assembly.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Withstands high surge stresses and offers flexible axial-lead mounting terminals
• Features minimal changes in voltage versus current as specified by voltage regulation

Applications

• Voltage regulation circuits requiring robust thermal performance
• Power supply protection against high surge stresses
• General purpose voltage reference applications

Procurement Notes

Verify that the specific part number matches the required suffixes for RoHS compliance (e3) and tape and reel packaging (TR). Confirm the manufacturer origin, as this component originates from the Microsemi Scottsdale Division. Ensure the procurement documentation aligns with the official datasheet specifications for the 1N5333B through 1N5388B series to guarantee correct electrical characteristics and mechanical dimensions.

Selection Notes

Select this component when a 62 V Zener voltage with ±5% tolerance is required for power dissipation up to 5.0 watts. Consider the T-18 axial package for through-hole mounting and verify compatibility with the specified operating temperature range of -65°C to +150°C. Evaluate the need for tape and reel packaging if automated surface or through-hole placement is utilized in the manufacturing process.

Part Context

This component belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes originally produced by Microsemi. The series covers a wide voltage selection from 3.3 V to 200 V. The 'B' suffix indicates a standard ±5% voltage tolerance, while the 'e3' suffix denotes RoHS compliance. The 'TR' suffix specifies the tape and reel packaging configuration.

Replacement Considerations

Equivalent parts include the 1N5372B without the e3/TR suffixes for non-RoHS or loose-pack requirements. Surface mount equivalents such as SMBJ5372B are available for space-constrained designs. Verify that any substitute maintains the 5-watt power rating and 62 V Zener voltage specification.
