Datasheet in PDF for the PZT2907A, a PNP small-signal transistor the file name rates at 60 V. This PZT part comes in a SOT-223 surface-mount package and works in general switching and amplifier roles on logic and power control boards. Technicians use the document to check pin assignment, maximum collector current, gain and saturation figures when identifying an SMD marking or picking a substitute. Measure the transistor out of circuit with a meter in diode mode to confirm a fault before replacing it. Opens in any PDF viewer.
