The CZT31C SOT-223 Bipolar Transistor, manufactured by Changjing Electronics Technology, is a RoHS-compliant, PNP transistor that features high gain, low-noise, and low-power consumption. It has a collector–base voltage (VCBO) of 30V and a collector–emitter voltage (VCEO) of 20V, a base-emitter voltage (VBE) of 1V, and a collector current rating (IC) of 1A. It is housed in a SOT-223(G) package and features an excellent switching performance with an optimal frequency of 600MHz. The CZT31C is ideal for use in high-frequency switching operations and applications.
