1N3175R

Single Diodes Overview

The 1N3175R is a silicon rectifier diode manufactured by Microchip Technology, housed in the DO-205AB (DO-9) stud mount package. It features a maximum repetitive peak reverse voltage of 1200 V and an average forward rectified current rating of 240 A. The device supports a non-repetitive peak forward surge current of 3000 A and operates within a junction temperature range of -65 °C to +200 °C. With a typical forward voltage drop of 1.25 V and a reverse leakage current of 75 µA at rated voltage, it is designed for high-power DC power conversion applications requiring robust thermal management via its screw-type mounting configuration.

Single Diodes Procurement Notes

Verify the specific manufacturer source, as historical production may involve transitions between Microsemi and Microchip Technology. Confirm the RoHS compliance status, as some listings indicate non-compliance while others may reflect updated manufacturing runs. Ensure the ordering suffix matches the required environmental or packaging specifications. Validate the lead time estimates directly with authorized distributors, as factory lead times can vary significantly based on production schedules and demand fluctuations.

Single Diodes Selection Notes

Select this component when high current and high voltage rectification are required in a single-phase configuration. The DO-205AB package necessitates a heatsink-compatible mounting surface due to the high power dissipation associated with 240 A operation. Consider the 1.25 V forward voltage drop for efficiency calculations in low-voltage, high-current output stages. Ensure the circuit design accommodates the 75 µA reverse leakage at maximum operating temperatures to prevent unintended biasing or noise issues in sensitive control circuits.

Single Diodes Part Context

The 1N3175R belongs to the standard rectifier diode family, specifically designed for general-purpose high-power applications. It utilizes a single-phase, one-way conduction structure with an anode-connected case for thermal coupling. The device is classified under discrete semiconductors and falls within the broader category of power diodes used in industrial and commercial power electronics systems.

Single Diodes Replacement Considerations

Cross-reference with other 1200 V, 240 A stud-mount rectifiers from compatible manufacturers. Verify pinout compatibility, specifically the anode-connected case configuration. Ensure thermal resistance characteristics match the existing heatsink design to maintain safe junction temperatures under identical load conditions.
