The FZT949TA is a 30V PNP medium power bipolar junction transistor designed for general-purpose switching and amplification applications. It features a maximum collector-emitter voltage of 30V and a continuous collector current rating of 5.5A, with a peak pulse current capability of 20A. The transistor offers a minimum DC current gain (hFE) of 100 at 1A collector current and 1V collector-emitter voltage, ensuring reliable performance in medium-power circuits.
Low saturation voltage characteristics are highlighted, with VCE(sat) typically below 140mV at 1A and a maximum of 440mV at 5.5A, reducing power losses in switching applications. The transition frequency (fT) is 100MHz, making it suitable for moderate-speed switching. Power dissipation is rated at 3W with a heatsink and 1.6W without, with thermal resistance from junction to ambient of 42°C/W (with heatsink) and 78°C/W (without).
The device is housed in a surface-mount SOT223 package with gull-wing leads, weighing approximately 0.112 grams. It is rated for operation over a junction temperature range of -55°C to 150°C. The FZT949TA is RoHS3 compliant, halogen-free, and has a moisture sensitivity level of 1 (unlimited). ESD protection is rated at 4000V HBM and 400V MM.
