The MMBTA56LT1G is a PNP silicon driver transistor designed for high-voltage applications. It features a collector-emitter voltage rating of -80 V and can handle a continuous collector current up to -500 mA. The device provides a minimum DC current gain (hFE) of 100 at a collector current of -100 mA, ensuring efficient operation. Key characteristics include a low collector-emitter saturation voltage of -0.25 V maximum and a minimum current-gain bandwidth product of 50 MHz. As a lead-free, RoHS-compliant device in a SOT-23 package, it is suitable for a wide range of driver and switching circuits where space is a constraint.
