Overview
The onsemi 1N5379BG is a single axial-lead Zener diode rated for 5 W power dissipation. It provides a nominal Zener voltage of 110 V with a tolerance of ±5%. The device operates within a temperature range of -65 °C to +150 °C junction temperature. Key electrical characteristics include a maximum reverse leakage current of 500 nA and a Zener impedance of 125 Ohms at the test current of 12 mA.
Feature Summary
- Provides stable voltage regulation at 110 V with high power handling capability.
- Designed for through-hole mounting using an axial lead configuration.
- Capable of reliable operation across a wide industrial temperature spectrum.
Applications
- Voltage reference circuits requiring stable 110 V levels.
- Overvoltage protection stages in power supply systems.
- Clamping applications in high-voltage signal processing paths.
Procurement Notes
Verify the specific suffix 'BG' against the manufacturer's official datasheet to confirm package details and compliance status. Ensure the procurement channel sources directly from authorized distributors to guarantee component authenticity and traceability. Cross-reference the part number with the latest revision history to avoid obsolete stock.
Selection Notes
Select this component when a robust 5 W axial Zener diode is required for 110 V regulation. Compare the 125 Ohm impedance against circuit sensitivity requirements. Verify that the axial form factor fits the available PCB real estate and thermal management constraints of the target design.
Part Context
This component belongs to the standard 1N53xx series of high-power Zener diodes manufactured by onsemi. The series is characterized by its rugged DO-201AA (axial) package, which supports significant power dissipation. It serves as a fundamental discrete semiconductor element for voltage control tasks in general electronics.
Replacement Considerations
Direct substitutes include the 1N5379B from Diotec Semiconductor and the 1N5379B-T from Diodes Incorporated. These parts share identical 110 V, 5 W specifications and DO-201 axial packaging. Verify pinout compatibility and thermal performance before final substitution.
