1N1363A

Overview

The 1N1363A is a silicon unidirectional Zener diode manufactured by Microchip Technology. It features a nominal Zener voltage of 33V with a tolerance of 5% and a maximum power dissipation of 10W. The component utilizes a DO-4 metal package with a post/stud mount configuration and contains a single terminal. It is classified as a leaded device that does not comply with RoHS standards.

Feature Summary

• High-power capability with 10W dissipation rating
• Robust metal DO-4 package construction
• Post/stud mounting for secure installation

Applications

• High-power voltage regulation circuits
• Industrial equipment protection
• Military and aerospace systems requiring rugged components

Procurement Notes

Verify compliance requirements before procurement, as the 1N1363A is explicitly identified as a leaded component that does not meet RoHS standards. Confirm that the DO-4 metal package and stud mount interface are compatible with the target assembly process. Ensure the design accommodates the specific thermal management needs associated with its 10W power dissipation rating in the final application environment.

Selection Notes

Select this component when high power handling and mechanical robustness are required over environmental compliance. The DO-4 metal case supports higher thermal performance compared to plastic packages. Verify that the 33V Zener voltage aligns with circuit requirements and that the unidirectional configuration suits the polarity constraints of the design.

Part Context

This part belongs to the standard Zener diode category within Microchip's discrete semiconductor portfolio. It serves legacy applications where high power density and durable metal packaging are prioritized. The DO-4 form factor is typical for older industrial and military specifications requiring reliable voltage reference or clamping under significant load conditions.

Replacement Considerations

Cross-reference with other 10W Zener diodes in the DO-4 package from various manufacturers. Ensure equivalent electrical parameters, specifically the 33V breakdown voltage and 5% tolerance, are maintained during substitution.
