SK320B R5G

Single Diodes Overview

The SK320B R5G is a surface-mount Schottky barrier rectifier manufactured by Taiwan Semiconductor Corporation. It features a single-phase, one-element silicon construction housed in a DO-214AA (SMB) plastic package with two terminals. The device is rated for a maximum repetitive peak reverse voltage of 200V and a maximum average forward rectified current of 3A. Key electrical parameters include a maximum instantaneous forward voltage of 0.85V at 3.0A and a maximum DC reverse current of 5.0mA at 200V. It supports a non-repetitive peak forward surge current of 70A and operates within a junction temperature range of -55°C to +125°C.

Single Diodes Procurement Notes

Verify the specific ordering suffix 'R5G' against official Taiwan Semiconductor documentation to confirm reel packaging specifications and moisture sensitivity level compliance. Ensure the component meets RoHS Directive 2011/65/EU requirements and WEEE standards as stated in manufacturer datasheets. Cross-reference the part number with the latest product change notices to confirm material composition and halogen-free status according to IEC 61249-2-21 definitions before procurement.

Single Diodes Selection Notes

Select this component for designs requiring low forward voltage drop and high switching efficiency in compact surface-mount layouts. The DO-214AA package suits space-constrained PCBs. Verify that the 200V reverse voltage rating exceeds the circuit's peak inverse voltage and that the 3A current rating accommodates both continuous and surge loads. Consider thermal management requirements given the 125°C maximum operating temperature limit.

Single Diodes Part Context

This part belongs to the SK3xB series of surface mount Schottky barrier rectifiers from Taiwan Semiconductor. The series utilizes guardring technology for enhanced reliability and is designed for high-volume automated assembly. These devices are engineered to replace bulkier through-hole rectifiers in modern power conversion applications, offering improved performance metrics within standard SMB packages.

Single Diodes Replacement Considerations

Compatible substitutes include other 3A 200V Schottky rectifiers in DO-214AA packages, such as those from Vishay or Diodes Inc., provided they match the forward voltage and reverse leakage specifications. Verify pinout compatibility and thermal resistance characteristics when evaluating alternatives.
