1N1358A

Overview

The Microchip Technology 1N1358A is a single Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 20 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. This component serves as a robust solution for maintaining stable reference voltages in high-power electronic circuits.

Feature Summary

• Provides precise voltage regulation at a 20 V nominal level
• Capable of handling high power dissipation up to 10 W
• Utilizes a durable stud mount construction for effective thermal management

Applications

• High-power voltage reference circuits
• Overvoltage protection systems
• Industrial power supply regulation

Procurement Notes

Verify the specific manufacturer source, as historical data indicates production by New Jersey Semi-Conductor Products before acquisition by Microchip. Confirm RoHS compliance status through current official documentation, as conflicting information exists regarding regulatory adherence. Ensure the DO-4 package variant matches the required mechanical mounting specifications for the intended assembly process.

Selection Notes

Select this component when a 20 V regulated output is required with significant power handling capabilities. The stud mount design necessitates appropriate heatsinking infrastructure to maintain thermal stability under full load conditions. Evaluate the ±5% voltage tolerance against circuit requirements to ensure adequate precision for the specific application environment.

Part Context

This part belongs to the standard Zener diode category, historically associated with New Jersey Semi-Conductor Products before being integrated into the Microchip Technology portfolio. The 1N series designation follows established semiconductor numbering conventions for general-purpose rectifier and regulator devices. The DO-4 package represents a legacy but reliable form factor for high-power discrete semiconductors.

Replacement Considerations

Consult official Microchip documentation for verified cross-reference part numbers. Online sources indicate potential alternatives are available; however, only substitute parts explicitly confirmed by the manufacturer should be considered to ensure electrical and mechanical compatibility.
