Case: TO-5, pinout=? Maximum ratings: PD: 150mW VCEO: 30V IC: 300mA Characteristics: hFE (IC=10mA): 80 min. fab ("frequency cutoff"): 12MHz (fT~9.6MHz) Cob: 20pF max. VCEsat (IC=10mA): 200mV max. > 2N508 "PNP germanium transistor for audio driver and low power output service in entertainment equipment."
