A alalbeet New Member Jul 22, 2009 #1 Hi all please help me to find these two datasheets of two transistors as follows C 331 59014 and the second is H 331 59012 I saw them in Infrared transmitter so I want to understand its function as i saw its stability thanks alot Last edited: Jul 22, 2009

C331 could be 2sc331 H331 appears to be SFH331, a photo transistor perhaps , www.alldatasheet.com helps you to download data sheets and understand. Last edited: Jul 22, 2009
