1N1354

Overview

The Microchip Technology 1N1354 is a single Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 13 V with a tolerance of ±10%. The device is rated for a maximum power dissipation of 10 W and has a maximum impedance (Zzt) of 2 Ohms. It is housed in a DO-203AA (DO-4) Stud package, suitable for high-power thermal management.

Feature Summary

• Provides stable voltage regulation at a nominal 13 V level
• Capable of handling high power dissipation up to 10 W
• Constructed in a robust DO-203AA stud mount package for efficient heat transfer

Applications

• High-power voltage reference circuits
• Overvoltage protection in industrial systems
• Voltage clamping in power supply outputs

Procurement Notes

Verify the manufacturer designation as Microchip Technology or its acquired entities like Micrel when sourcing. Confirm the package type matches DO-203AA/DO-4 specifications. Ensure RoHS compliance status aligns with project requirements. Cross-reference part numbers carefully as legacy designations may vary across distributors.

Selection Notes

Select this component when a 13 V Zener voltage with 10 W power rating is required. The low impedance of 2 Ohms supports effective regulation under varying current conditions. The stud mount package necessitates appropriate heatsinking or chassis mounting infrastructure for optimal thermal performance during operation.

Part Context

This component belongs to the standard Zener diode family used for voltage regulation. It serves as a discrete semiconductor solution for maintaining constant voltage levels in electronic circuits. The DO-4 package is a traditional axial leaded style often used in through-hole applications requiring higher power handling than surface-mount alternatives.

Replacement Considerations

The 1N3014 is listed as a related part number in some catalogs, though it specifies an 180 V rating which differs significantly from the 13 V requirement of the 1N1354. Verify exact electrical parameters before substituting any alternative Zener diodes to ensure voltage and power compatibility.
