The ROHM 2SA1797T100Q is a PNP bipolar junction transistor designed for medium-power switching and amplification applications. It offers a maximum collector-emitter breakdown voltage of -50V and a DC collector current rating of -3A (pulse capability up to -6A). The device features a low collector-emitter saturation voltage of -0.35V max at IC/IB = -1A/-50mA, reducing power losses in saturated switching circuits.
The DC current gain (hFE) is typically 200 at VCE = -2V, IC = -1.5A, ensuring consistent performance across operating conditions. The transition frequency (fT) is 200 MHz, supporting moderate-speed switching. Output capacitance (Cob) is 45 pF typical, suitable for general-purpose use.
This transistor is housed in a surface-mount MPT3 package (TO-243AA), with dimensions 4.5 x 2.5 mm and a low profile (1.6 mm height). Power dissipation is 0.5W without a heatsink and 2W when mounted on a 40x40x0.7mm ceramic board. The operating junction temperature range is up to 150°C. The part is supplied in tape-and-reel packaging with a standard quantity of 1000 pieces per reel.
