1N5834

Overview

The Microchip Technology 1N5834 is a silicon Schottky rectifier diode designed for high-efficiency power applications. It features a single configuration housed in the DO-5 stud mount package, with the case serving as the cathode connection. The device supports an average forward current of 40 A and a repetitive peak reverse voltage of 40 V. Key electrical characteristics include a maximum non-repetitive peak forward surge current of 800 A and a low forward voltage drop of 750 mV at rated current. It operates within a junction temperature range of -65 °C to +150 °C.

Feature Summary

• Utilizes Schottky barrier technology to minimize forward voltage drop and enhance energy efficiency.
• Features a robust stud mount construction with the case connected to the cathode for effective thermal dissipation.
• Designed specifically for free-wheeling diode applications to improve circuit performance.

Applications

• Free-wheeling diode circuits
• High-efficiency power rectification systems

Procurement Notes

Verify the manufacturer origin carefully, as the 1N5834 designation is utilized by multiple vendors including GeneSiC Semiconductor and NXP. Confirm that the specific unit received matches the required package style and terminal configuration. Ensure the component meets the necessary environmental compliance standards for your specific deployment before integration.

Selection Notes

Select this component when a high-current, low-voltage rectifier with superior switching efficiency is required. The stud mount format is ideal for chassis mounting where heat sinking is critical. Consider the 40 V rating and 40 A capacity against your system's peak load and voltage stress requirements to ensure adequate safety margins.

Part Context

This device belongs to the 1N58 series of Schottky rectifiers, which are widely recognized for their ability to handle significant currents in low-voltage environments. The series offers a balance of high surge capability and low conduction losses, making it suitable for industrial and automotive power supplies where reliability under heavy loads is essential.

Replacement Considerations

Cross-reference with other manufacturers offering the 1N5834 part number, such as GeneSiC Semiconductor or NXP, to verify pinout and thermal compatibility. Ensure any substitute maintains the same DO-5 package dimensions and stud mounting specifications.
