BAT43W RHG

Single Diodes Overview

The BAT43W RHG is a single Schottky barrier diode manufactured by Taiwan Semiconductor. It features a silicon construction in an SMD/SMT surface mount package. Key electrical parameters include a maximum repetitive reverse voltage (Vrrm) of 30 V and a forward current (If) of 200 mA. The device exhibits a maximum forward voltage (Vf) of 1 V at the rated current, with a peak non-repetitive forward surge current (Ifsm) capability of 4 A. Reverse leakage current (Ir) is specified at 500 nA. The component operates within a junction temperature range of -55°C to +125°C.

Single Diodes Feature Summary

• Utilizes Schottky barrier technology for low forward voltage drop characteristics
• Designed for fast switching applications due to minimal reverse recovery time
• Constructed in a compact surface mount package suitable for automated insertion

Single Diodes Applications

• High-frequency rectification in power supply circuits
• Clamping and protection in RF signal paths
• Free-wheeling diodes in DC-DC converter topologies

Single Diodes Procurement Notes

Verify the specific suffix RHG against the manufacturer's official datasheet to confirm exact packaging configuration and compliance status. Ensure the ordering part number matches the required tape and reel specifications for your assembly line equipment. Cross-reference the RoHS declaration directly with Taiwan Semiconductor documentation prior to procurement to guarantee regulatory adherence for your target market.

Single Diodes Selection Notes

Select this component when a low-profile surface mount Schottky diode is required for 30 V reverse voltage applications. The 200 mA continuous current rating suits low-power signal processing or small-signal rectification tasks. Consider the 4 A surge current capacity for circuits experiencing transient load spikes. Verify that the SOD-123 footprint aligns with the existing PCB layout constraints and thermal management requirements of the design.

Single Diodes Part Context

This component belongs to the BAT43 series of surface mount Schottky barrier diodes. It shares functional similarities with other industry-standard variants such as BAT42 and BAT43, offering comparable performance in terms of forward voltage and switching speed. The device is designed to replace older through-hole equivalents in modern miniaturized electronic assemblies while maintaining reliable operation across industrial temperature ranges.

Single Diodes Replacement Considerations

Direct substitutes include BAT43W-E3-08 from Vishay and BAT43W-7 from Diodes Incorporated. These alternatives share identical pinouts and similar electrical ratings. Verify package dimensions and marking codes before substitution to ensure mechanical compatibility.
