WKPSO8-TP overview

WKPSO8-TP is a component documented by IC-Haus GmbH. The PDF description identifies it as "15 V CW P-TYPE LASER DIODE DRIVER." This guide condenses the most useful engineering information from the available PDF so that designers and sourcing teams can identify the checks that still need confirmation in the original document.

Specifications and operating details

The following points were extracted from the PDF text. Check the associated conditions, notes and limits in the complete document before using a value in a design.

  • if the laser diode is damaged or the feedback current path fails) ♦ Second feedback input MDA also permits the operation of N-type laser diodes ♦ Modulation via the feedback inputs possible ♦ Wide monitor current range from 2.5 µA to 6.25.
  • The monitor current acts as a reference and is regulated independent of the in- fluence of temperature and supply voltage (range: 2.5 µA to 6.25 mA).

Engineering review checklist

  • Confirm repetitive reverse voltage, average forward current, surge current and leakage at the intended temperature.
  • Check forward-voltage loss and reverse-recovery behavior at the actual current and switching frequency.
  • Review package thermal resistance, copper area, polarity marking and transient derating before layout release.

Always confirm values against the latest manufacturer-controlled datasheet, especially when qualifying a substitute or releasing a production BOM.
