1N5379B

Overview

The Diotec Semiconductor 1N5379B is a non-planar silicon Zener diode designed for voltage stabilization and regulation. It features a nominal Zener voltage of 110 V with a standard tolerance of ±5%. The device supports a maximum power dissipation of 5 W at an ambient temperature of 50°C, utilizing the DO-201 axial through-hole package. Key electrical characteristics include a test current of 12 mA, a dynamic resistance of 125 Ohms at 1 mA, and a reverse leakage current of 500 nA at 83.6 V. The component operates within a junction temperature range of -50°C to +150°C.

Feature Summary

• High power dissipation capability up to 5 W in a rugged DO-201 axial leaded package
• Non-planar technology construction providing stable voltage regulation across a wide operating range
• Compliant with RoHS directives (excluding exemption 7a-I) and REACH regulations

Applications

• Voltage stabilization circuits
• Voltage regulators
• Overvoltage protection applications

Procurement Notes

Verify that the specific order matches the manufacturer part number 1N5379B from Diotec Semiconductor. Confirm compliance requirements such as RoHS status and AEC-Q101 qualification if automotive grade is needed, noting that standard versions are commercial/industrial grade. Ensure the procurement specification aligns with the DO-201 package dimensions and thermal management requirements for 5 W operation.

Selection Notes

Select this component when a high-voltage Zener reference around 110 V is required with significant power handling capacity. The DO-201 package is suitable for through-hole mounting where higher thermal mass is beneficial. Consider the 125 Ohm dynamic impedance for regulation precision needs. Verify that the application environment stays within the specified -50°C to +150°C junction temperature limits.

Part Context

This component belongs to the Diotec 1N5345B through 1N5388B series of non-planar Zener diodes. The series covers a broad voltage range from 8.7 V to 200 V, all sharing the same 5 W power rating and DO-201 mechanical outline. The 1N5379B specifically addresses the 110 V segment of this standardized lineup.

Replacement Considerations

Cross-reference with other manufacturers' 1N5379B equivalents ensuring identical 110 V Zener voltage, 5 W power rating, and DO-201 package compatibility. Verify dynamic resistance and leakage current specifications match design constraints.
