Important notice Dear Customer, On 7 February 2017 the former NXP Standard Product business became a new company with the tradename Nexperia. Nexperia is an industry leading supplier of Discrete, Logic and PowerMOS semiconductors with its focus on the automotive, industrial, computing, consumer and wearable application markets In data sheets and application notes which still contain NXP or Philips Semiconductors references, use the references to Nexperia, as shown below. Instead of PEMB18 PUMB18 PNP/PNP resistor-equipped transistors R1 = 4.7 k , R2 = 10 k Rev. 5 21 December 2011 Product data sheet 1.
