CZT5551 Description

Short technical summary and product information.

The Central Semiconductor CZT5551 is a silicon NPN transistor manufactured using the epitaxial planar process and epoxy molded in a surface mount package. It is specifically designed for high voltage amplifier applications.

Key electrical characteristics include a collector-emitter voltage (VCEO) of 160V and a continuous collector current (IC) of 600mA. The power dissipation (PD) is rated at 2.0W. The transistor operates within a junction temperature range of -65 to +150°C.

Electrical specifications detail various parameters such as collector cutoff current (ICBO) and emitter cutoff current (IEBO). It also specifies collector-emitter saturation voltage (VCE(SAT)) and base-emitter saturation voltage (VBE(SAT)) under different current conditions. The DC current gain (hFE) ranges from 80 to 250 at IC=10mA, and the transition frequency (fT) is between 100 and 300MHz at 100MHz.

The CZT5551 is housed in a SOT-223 surface mount package. Lead code designation is: 1) Base, 2) Collector, 3) Emitter, 4) Collector. Dimensions for the SOT-223 case are provided in both millimeters and inches.
