1N1375

Overview

The 1N1375 is a single Zener diode manufactured by Microchip Technology, designed for voltage regulation applications. It features a nominal Zener voltage of 100 V with a tolerance of ±10%. The device supports a maximum power dissipation of 10 W and has a maximum impedance (Zzt) of 40 Ohms. It utilizes a stud mount configuration and is housed in the DO-203AA package.

Feature Summary

• Provides stable voltage regulation at 100 V nominal level
• Capable of handling high power dissipation up to 10 W
• Utilizes robust stud mount construction for thermal management

Applications

• High-power voltage reference circuits
• Overvoltage protection systems
• Industrial power supply regulation

Procurement Notes

Verify the specific datasheet revision and mechanical dimensions against your PCB layout requirements before ordering. Confirm that the stud mount style matches your heat sinking infrastructure. Ensure the 10 W power rating aligns with your thermal design calculations under expected operating conditions.

Selection Notes

Select this component when a 100 V Zener reference with high power handling is required. The stud mount option facilitates direct attachment to heatsinks or chassis ground, improving thermal performance compared to leaded packages. Consider the 40 Ohm impedance limit for dynamic regulation needs.

Part Context

This part belongs to the family of single Zener diodes produced by Microchip Technology. It serves as a discrete semiconductor solution for maintaining precise voltage levels in electronic circuits where standard small-signal diodes lack sufficient power capacity.

Replacement Considerations

Check for equivalent 100 V, 10 W Zener diodes in the DO-203AA package from other manufacturers. Verify pinout compatibility and thermal resistance characteristics if substituting with parts from different suppliers.
