1N1368A

Overview

The 1N1368A is a Zener diode voltage regulator manufactured by Microchip Technology. It features a nominal Zener voltage of 51 V with a tolerance of ±5%. The device has a maximum power dissipation of 10 W and a maximum impedance (Zzt) of 8 Ohms. It utilizes a stud mount configuration and is housed in the DO-203AA (DO-4) package.

Feature Summary

• Provides stable voltage regulation at 51 V nominal
• High power handling capability up to 10 W
• Robust stud mount construction for thermal management

Applications

• Voltage reference circuits
• Overvoltage protection
• Power supply regulation

Procurement Notes

Verify the specific datasheet version from Microchip Technology to confirm exact electrical characteristics and mechanical dimensions. Ensure the DO-203AA package style matches your thermal design requirements. Confirm that the 10 W power rating aligns with your system's heat dissipation capabilities under operating conditions.

Selection Notes

Select this component when a precise 51 V reference or regulation point is required in high-power applications. The stud mount option facilitates direct mounting to heatsinks, making it suitable for environments where efficient thermal transfer is critical for maintaining performance and reliability over time.

Part Context

This part belongs to the 1N136 series of Zener diodes produced by Microchip Technology. These components are designed for general-purpose voltage regulation tasks. The 1N1368A specifically offers higher power handling compared to lower-wattage variants in the same family, supporting more demanding circuit loads.

Replacement Considerations

Check for compatible 1N136 series equivalents from other manufacturers that meet the 51 V, 10 W, and DO-203AA specifications. Verify pinout compatibility and thermal resistance values before substituting.
