NXP 500 mA resistorequipped transistors (RETs) PDTD and PDTB series 500 mA RETs for Automotive applications Developed specifically for the automotive and industrial market, 500 mA RETs combine one or two resistors with a transistor to provide an optimal integrated solution for digital applications. Key features Ñ Built-in bias resistors Ñ 500 mA collector current capability Ñ ± 10 % resistor tolerance Ñ 5 different resistor combinations (more on request) Ñ double versions in SOT457 (SC-74) on request Key benefits Ñ lower handling and inventory costs Ñ reduced boardspace Ñ shorter assembly times Ñ reduced pick-and-place efforts Ñ simpler design process Ñ increased end product reliability due to fewer soldering points Key applications Ñ digital applications in automotive and industrial segments Ñ switching loads Ñ controlling IC inputs Ñ cost saving alternative for BC807/BC817 and their base resistors in digital applications Application examples VCC from logic mse235 RETs to switch loads up to 500 mA 500 mA RET PDTB series power supply load R2 R1 control input 100 mA RET PDTC series bra285 Loadswitch using a 500 mA PNP RET www.nxp.com © 2008 NXP B.V.
