Application Scenarios & Design Considerations

Small Signal Fast Switching Diode

Alternative Part Number

  • SIR-142W --: Infrared emitting diode with similar 142-series wavelength and package style, widely used as a drop-in substitute for AUK SDS142WM.
  • IR333-A --: Standard 5mm infrared LED with comparable forward current and wavelength, commonly cross-referenced for AUK IR emitters.
  • TSAL6200 --: High-reliability 940nm IR emitter with similar electrical characteristics, suitable alternative when AUK parts are unavailable.
  • SDS142W --: Same SDS142 series photodiode with nearly identical optical and electrical characteristics, differing only in package variant, making it a direct drop-in substitute.
  • BPW34 --: Widely available silicon PIN photodiode with comparable spectral response and sensitivity, commonly used as a cross-reference for Kodenshi photodiodes.
  • SFH203 --: Industry-standard silicon PIN photodiode with similar responsivity and fast response, suitable as a functional replacement when exact Kodenshi part is unavailable.
