1N1371

Overview

The Microchip Technology 1N1371 is a Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 68 V with a tolerance of ±10%. The device is rated for a power dissipation of 10 W and utilizes the DO-203AA (DO-4) stud mount package. This component maintains a fixed output voltage despite variations in input, serving as a reliable regulator in electronic circuits.

Feature Summary

• Provides stable voltage regulation by maintaining a fixed output voltage under varying input conditions
• Capable of handling high power dissipation for robust performance in demanding environments
• Utilizes a stud mount package configuration suitable for secure mechanical attachment

Applications

• Voltage regulation in power supply circuits
• Overvoltage protection systems
• Reference voltage generation in electronic instrumentation

Procurement Notes

Verify the manufacturer designation, as some listings associate this part number with IR. Confirm the package type is DO-203AA and the voltage rating is 68 V. Ensure compliance with RoHS standards if required. Cross-reference datasheets to confirm the 10 W power rating matches your specific thermal requirements before procurement.

Selection Notes

Select this component when a 68 V Zener reference is required with high power handling capabilities. The DO-203AA package necessitates appropriate heatsinking or mounting hardware due to its stud mount design. Consider the ±10% tolerance for precision requirements and ensure the operating temperature range aligns with the application environment.

Part Context

The 1N1371 belongs to the family of single Zener diodes manufactured by Microchip Technology. It is categorized under voltage regulator diodes intended for general-purpose regulation tasks. The component is widely distributed through electronic supply chains and is often referenced in circuit designs requiring stable high-voltage references.

Replacement Considerations

Aftermarket sources list this part as replaceable by IR-branded equivalents. Verify electrical specifications match exactly when substituting. Ensure the replacement maintains the same DO-203AA package dimensions for mechanical compatibility.
