ONSEMI SMMBTA56LT1G PNP Driver Transistor

The PNP Silicon Driver Transistor is a high-quality, AEC-Q101 qualified device suitable for automotive applications requiring reliable control and switching. Constructed with Pb-Free, Halogen Free/BFR Free, and RoHS compliant materials, it offers robust performance. The transistor features a collector-emitter voltage of -60 V for MMBTA55 and -80 V for MMBTA56, with continuous collector current of -500 mA. It has low thermal resistance, with a maximum junction-to-ambient of 556°C/W on FR-5 boards. Designed for durability, it operates within -55°C to +150°C temperatures, ideal for automotive and industrial use.
