1N5372BG

Overview

The onsemi 1N5372BG is a single axial-lead Zener diode with a nominal voltage of 62 V and a power dissipation rating of 5 W. It features a 5% voltage tolerance and operates within a temperature range of -65 °C to +150 °C. Key electrical parameters include a maximum reverse leakage current of 500 nA, a Zener impedance of 42 Ohms, and a test current of 20 mA. The device utilizes an 017AA-2 package.

Feature Summary

• Provides stable voltage regulation at 62 V with high thermal stability up to 150 °C
• Capable of handling 5 W power dissipation for robust circuit protection
• Low leakage current ensures minimal standby power loss

Applications

• Voltage reference circuits requiring precise 62 V levels
• Overvoltage protection in industrial power supplies
• Clamping applications in high-power electronic systems

Procurement Notes

Verify the specific suffix 'BG' against official manufacturer documentation to confirm exact binning or testing criteria, as suffixes often denote specific manufacturing lot attributes rather than functional changes. Ensure compatibility with axial mounting requirements and verify RoHS compliance status through the latest datasheet before integration into production designs.

Selection Notes

Select this component when a 5 W axial Zener diode is required for high-power voltage regulation. The 62 V nominal value suits applications needing stable references above common low-voltage options. Consider the 42 Ohm impedance for dynamic load variations and ensure the operating environment stays within the specified -65 °C to +150 °C range for reliable performance.

Part Context

This part belongs to the 1N53 series of high-power Zener diodes manufactured by onsemi. The series is designed for general-purpose voltage regulation and protection in demanding environments. The 1N5372 variant specifically targets the 62 V segment, offering a balance of voltage precision and power handling capability suitable for industrial and commercial electronics.

Replacement Considerations

Cross-reference with other manufacturers' 1N5372 equivalents ensuring identical 62 V, 5 W, and axial package specifications. Verify pinout compatibility and thermal characteristics to maintain circuit integrity during substitution.
