DIODES INC. FMMT617 Power Transistor

The FMMT617 is an NPN silicon power switching bipolar transistor featuring a maximum power dissipation of 625mW, supporting peak pulse currents of 12A and low saturation voltage. It exhibits excellent current gain (hFE) up to 12A, operates reliably across a wide temperature range from -55°C to 150°C, and has matte tin-plated leads for solderability. Designed for power management, DC-DC modules, and industrial applications, it complies with RoHS and is qualified to high reliability standards including AEC-Q101. Its compact SOT23 package makes it suitable for space-constrained electronics.
