SR4050PTH

Diode Arrays Overview

The SR4050PTH is a Schottky Barrier Rectifier manufactured by Taiwan Semiconductor Corporation. It features a single diode configuration with a maximum average forward rectified current of 4 Amperes and a peak repetitive reverse voltage rating of 50 Volts. The device utilizes a DO-201AD (DO-204AH) axial leaded package, designed for through-hole mounting on printed circuit boards. Key electrical characteristics include a low forward voltage drop to minimize conduction losses and a high surge current capability to withstand transient overloads. The component is engineered for general-purpose rectification applications requiring reliable performance in power supply circuits.

Diode Arrays Feature Summary

• Schottky barrier construction ensures fast switching speeds and minimal reverse recovery time.
• Low forward voltage drop reduces power dissipation and improves overall system efficiency.
• High surge current capability provides robust protection against transient overload conditions.

Diode Arrays Applications

• General-purpose rectification in AC/DC power supply circuits
• Free-wheeling diodes in DC-DC converter topologies
• Polarity protection circuits in electronic devices

Diode Arrays Procurement Notes

Verify the specific suffix 'PTH' confirms the axial leaded package variant when sourcing. Ensure the manufacturer is identified as Taiwan Semiconductor Corporation to distinguish from other brands using similar part numbers. Confirm RoHS compliance status if required by project specifications. Cross-reference the datasheet for exact thermal resistance values during PCB layout planning.

Diode Arrays Selection Notes

Select this component for applications requiring efficient rectification at moderate voltages up to 50V. The 4A current rating suits medium-power designs where thermal management is feasible via standard through-hole mounting. Consider the axial package constraints for board space compared to surface-mount alternatives. Evaluate the forward voltage characteristics against system efficiency targets.

Diode Arrays Part Context

This component belongs to the family of Schottky Barrier Rectifiers offered by Taiwan Semiconductor Corporation. These devices are characterized by their use of metal-semiconductor junctions rather than traditional PN junctions, resulting in superior high-frequency performance. The series typically includes various voltage and current ratings to cover diverse industrial and consumer electronics requirements.

Diode Arrays Replacement Considerations

Check for equivalents such as the SR4050 from other manufacturers like Vishay or Diodes Inc., ensuring identical package dimensions and electrical ratings. Verify that any substitute maintains the same DO-201AD footprint and lead spacing for direct replacement without PCB modification.
