1N1354A

Overview

The Microchip Technology 1N1354A is a single Zener diode designed for voltage regulation and reference applications. It features a nominal Zener voltage of 13V with a power dissipation rating of 10W. The component is housed in the DO-203AA (DO-4) axial leaded package, suitable for stud mounting or standard through-hole PCB integration. This device provides stable voltage clamping characteristics within its specified operating range.

Feature Summary

• Provides stable 13V Zener reference voltage
• Supports high power dissipation up to 10W
• Utilizes robust DO-203AA axial leaded package

Applications

• Voltage regulation circuits
• Overvoltage protection systems
• General purpose rectification and clamping

Procurement Notes

Verify the manufacturer source carefully, as listings may attribute this part to IR Industrial Controls or BSC despite Microchip being the primary producer. Confirm the package type is DO-203AA/DO-4 and that the description explicitly states 'DIODE ZENER 13V 10W'. Ensure RoHS compliance status matches project requirements before finalizing procurement orders.

Selection Notes

Select this component when a 10W power handling capability is required for 13V regulation tasks. The DO-203AA package allows for direct stud mounting, which aids in thermal management for high-power applications. Compare against lower-power Zener alternatives if system constraints do not necessitate the 10W dissipation rating.

Part Context

This component belongs to the family of single Zener diodes manufactured by Microchip Technology. It serves as a discrete semiconductor solution for maintaining constant voltage levels in electronic circuits. The DO-203AA package is a traditional glass-encapsulated axial leaded style, widely used in industrial and commercial power supplies.

Replacement Considerations

Check for equivalents from other manufacturers offering identical 13V Zener voltage and 10W power ratings in the DO-203AA package. Verify pinout compatibility and thermal resistance specifications to ensure seamless substitution in existing designs without circuit modification.
