1N5372B

Overview

The Diotec Semiconductor 1N5372B is a non-planar silicon unidirectional Zener diode designed for voltage stabilization and regulation. It features a nominal Zener voltage of 62 V with a standard tolerance of ±5%. The device supports a maximum power dissipation of 5 W at 50°C ambient temperature and can withstand non-repetitive peak surge power up to 80 W. It operates within a junction temperature range of -50°C to +150°C and utilizes the DO-201 axial through-hole package.

Feature Summary

• High power dissipation capability suitable for robust voltage regulation applications
• Non-planar technology construction ensuring stable performance across operating ranges
• Compliant with RoHS directives and REACH regulations

Applications

• Voltage stabilization circuits
• Linear voltage regulators
• Overvoltage protection (uni-directional)

Procurement Notes

Verify that the specific order matches the exact part number 1N5372B, as this series includes multiple voltage variants. Confirm compliance requirements such as RoHS status if applicable to your manufacturing process. Ensure the procurement documentation references the correct datasheet version to validate thermal resistance and maximum ratings against current design specifications.

Selection Notes

Select this component when a 62 V reference or clamp is required in a high-power environment. The DO-201 package provides adequate thermal mass for 5 W continuous dissipation under proper heatsinking or lead-length conditions. Consider the dynamic impedance characteristics for precision regulation needs and ensure the circuit design accommodates the specified surge current limits during transient events.

Part Context

This component belongs to the 1N5345B through 1N5388B series of 5 W Zener diodes manufactured by Diotec Semiconductor. The series covers a wide voltage range from 8.7 V to 200 V using non-planar diffusion technology. These devices are standardized commercial/industrial grade components intended for general-purpose electronic applications requiring reliable voltage control.

Replacement Considerations

Cross-reference with other manufacturers' 1N5372B equivalents to verify pinout compatibility and thermal resistance values. Ensure substitute parts meet the same 5 W power rating and 62 V nominal voltage tolerance.
