1N5372BE3/TR8

Overview

The Microchip Technology 1N5372BE3/TR8 is a silicon 5-watt Zener diode with a nominal voltage of 62 V and ±5% tolerance. It operates in the -65°C to +150°C range, featuring a maximum reverse leakage current of 0.5 µA at 44.6 V and a dynamic impedance of 42 Ohms. The component utilizes an axial T-18 package and includes a TR suffix for tape-and-reel packaging.

Feature Summary

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

Applications

• Voltage regulation circuits requiring 5-watt power dissipation
• High-current applications supported by adequate heat sinking
• Surge protection environments due to high stress tolerance

Procurement Notes

Verify the specific B suffix indicates the standard ±5% tolerance configuration. Confirm the TR suffix denotes tape-and-reel packaging rather than bulk. Ensure the e3 suffix confirms RoHS compliance status. Cross-reference the manufacturer's latest documentation to validate current production availability and any potential obsolescence notices.

Selection Notes

Select this component when a 62 V reference point is required within a 5-watt power budget. The T-18 axial package suits through-hole designs needing robust mechanical leads. Verify thermal management requirements against the specified junction-to-lead resistance to ensure safe operation under steady-state conditions.

Part Context

This device belongs to the JEDEC registered 1N5333B through 1N5388B series of silicon Zener diodes. The series covers a wide voltage spectrum from 3.3 V to 200 V. The 1N5372 variant specifically addresses mid-range voltage regulation needs within this standardized family.

Replacement Considerations

Compatible equivalents include the 1N5372B without the e3/TR suffixes or surface mount variants like SMBJ5372B.
