1N1375A

Overview

The 1N1375A is a single Zener diode voltage regulator manufactured by Microchip Technology. It features a nominal Zener voltage of 100 V with a tolerance of ±5%. The device is rated for a maximum power dissipation of 10 W and utilizes a stud mount configuration within the DO-203AA (DO-4) package. It operates as a standalone voltage reference component suitable for high-power regulation applications.

Feature Summary

• Provides stable voltage regulation at a fixed 100 V nominal level
• Capable of handling up to 10 W of power dissipation
• Designed for robust stud mount installation in industrial environments

Applications

• High-voltage power supply regulation circuits
• Industrial equipment voltage reference stages
• Overvoltage protection networks requiring 100 V clamping

Procurement Notes

Verify the specific manufacturer suffix or revision code on the datasheet to ensure compatibility with your design requirements. Confirm that the DO-203AA package dimensions match your thermal management and mounting constraints. Check for RoHS compliance status if required by your manufacturing standards.

Selection Notes

Select this component when a precise 100 V reference is needed with significant power handling capabilities. Ensure the circuit design accounts for the thermal resistance associated with stud mounting. Compare against lower-power planar packages if space is limited, noting that stud mounts offer superior heat dissipation for high-wattage regulators.

Part Context

This part belongs to the family of discrete Zener diodes used for voltage regulation. Unlike low-power surface-mount variants, the 1N1375A is engineered for through-hole or chassis-mounted applications where higher current and power levels are prevalent. It serves as a fundamental passive component in analog and power electronics designs.

Replacement Considerations

Public confirmed substitute part numbers are not provided in the available documentation. Verify electrical equivalence, specifically the 100 V rating and 10 W power limit, before considering alternative manufacturers.
