1N5375B

Overview

The Diotec Semiconductor 1N5375B is a non-planar silicon Zener diode housed in a DO-201 axial leaded package. It provides a nominal Zener voltage of 82 V with a standard tolerance of ±5%. The device supports a maximum power dissipation of 5 W at an ambient temperature of 50°C and operates within a junction temperature range of -50°C to +150°C. Key electrical characteristics include a test current of 15 mA, a dynamic resistance of 65 Ω, and a reverse leakage current of 0.5 μA at 720 V.

Feature Summary

• High power dissipation capability up to 5 W for robust thermal performance
• Non-planar technology ensuring stable voltage regulation across the operating range
• Compliant with RoHS directives (excluding exemption 7a-I) and REACH regulations

Applications

• Voltage stabilization circuits
• Linear voltage regulators
• Overvoltage protection applications

Procurement Notes

Verify that the specific order matches the Diotec Semiconductor manufacturer designation. Confirm compliance requirements such as RoHS status and AEC-Q101 qualification if automotive grade is needed. Ensure the procurement documentation references the correct datasheet version to validate mechanical dimensions and soldering conditions.

Selection Notes

Select this component when a high-power 82 V reference is required in an axial package. Verify that the circuit can accommodate the 65 Ω dynamic impedance and 15 mA test current. Ensure the design allows for adequate heat sinking or airflow to maintain the junction temperature below 150°C under full load conditions.

Part Context

This part belongs to the 1N5345B through 1N5388B series of glass passivated Zener diodes manufactured by Diotec Semiconductor. The series covers a wide voltage range from 8.7 V to 200 V, all sharing the same 5 W power rating and DO-201 plastic case material. These components are designed for commercial and industrial grade applications requiring reliable voltage clamping.

Replacement Considerations

Other manufacturers producing parts in the 1N53xxB series may offer functional equivalents. Verify that any substitute maintains the 82 V nominal voltage, 5 W power rating, and DO-201 package form factor to ensure compatibility with existing board layouts and thermal constraints.
