PNP resistor-equipped transistor in a SOT323 (SC-70) surface-mount package, designed for switching applications with built-in bias resistors and a maximum collector current of 500 mA. The device is AEC-Q101 qualified and rated for operation up to 175 °C. The collector-emitter voltage is rated at -50 V, and the input voltage range depends on the specific variant. The bias resistor R1 for the PDTB143EU variant is specified as 4.7 kΩ with a 10% tolerance, and the R2/R1 ratio is 2.13-2.34. The same ratings apply to all variants in the PDTB1xxxU series, including those with trailing ordering codes such as PDTB143EUX.
