The PN2907A, MMBT2907A, and PZT2907A are 60 V PNP bipolar transistors designed for use as a general-purpose amplifier or switch in applications that require up to 500 mA. Offered in an ultra-small surface-mount package (SOT-223), the PZT2907A is ideal for spaceconstrained systems. The NPN complementary types are the PN2222A, MMBT2222A, and PZT2222A; respectively.
