SR20150PT

Diode Arrays Overview

The SR20150PT is a dual common cathode Schottky barrier rectifier manufactured by Taiwan Semiconductor. It features a silicon construction housed in a TO-3P (TO-247AD) package with three terminals. The device is rated for a continuous forward current of 20A and a repetitive peak reverse voltage of 150V. Key electrical characteristics include a maximum forward voltage drop of 0.85V at rated conditions and a non-repetitive peak surge current capability of 200A. The component operates within a junction temperature range of -55°C to +175°C, ensuring reliability in high-temperature environments.

Diode Arrays Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm pinout compatibility and packaging type. Ensure the procurement source provides valid RoHS compliance documentation consistent with the SR20150PT specifications. Cross-reference the part number with the latest Taiwan Semiconductor product change notices to avoid obsolete variants.

Diode Arrays Selection Notes

Select this component when a dual Schottky rectifier with a 20A current rating and 150V blocking voltage is required. The TO-3P package is suitable for through-hole mounting where higher thermal dissipation is necessary compared to surface-mount options. Consider the 0.85V forward voltage drop impact on overall system efficiency during thermal design calculations.

Diode Arrays Part Context

This component belongs to the SR series of Schottky barrier rectifiers from Taiwan Semiconductor. The series utilizes silicon technology optimized for low forward voltage and high surge current handling. The dual common cathode arrangement allows for compact circuit designs in single-phase applications, replacing discrete single-diode setups while maintaining high reliability standards.

Diode Arrays Replacement Considerations

Consult official substitution guides for equivalent dual Schottky rectifiers with matching 20A/150V ratings and TO-3P packages. Verify that any substitute maintains identical pin configurations and thermal characteristics to ensure direct compatibility without circuit modification.
