The device features high DC current gain (hFE minimum 100 at IC=-500mA) and low collector-emitter saturation voltage (-0.5V max at IC=-1A), making it well-suited for driver circuits, load switches, and power management applications. The transition frequency of 60 MHz typical supports switching applications up to moderate frequencies. The SOT-223 package provides a compact footprint with adequate power dissipation capability (2W at TA=25C). A complementary NPN type (FZT688BTA) is available for push-pull amplifier and bridge configurations.","working_principle":"The FZT788BTA is a PNP bipolar junction transistor operating in common-emitter or common-collector configurations. (1) PNP Structure: Three semiconductor layers (P-Emitter, N-Base, P-Collector) form two P-N junctions. Current flows from emitter to collector (conventional current direction) when the base-emitter junction is forward biased (VBE negative relative to emitter). (2) Current Amplification: A small base current (IB) controls a larger collector current (IC) with the current gain hFE = IC\/IB. With hFE minimum of 100, only 5mA base current can control up to 500mA collector current. (3) Saturation: When base current is sufficient, the transistor enters saturation where VCE drops to VCE(sat) = -0.5V max, minimizing power dissipation in switching applications. (4) Power Dissipation: Total power is calculated as P = VCE x IC. The SOT-223 package thermal resistance allows 2W dissipation at 25C ambient with appropriate PCB copper area.","pin_description":"
