FMMT6517TA

The FMMT6517TA is an NPN bipolar junction transistor designed for high-voltage switching and amplification applications. It offers a minimum collector-emitter breakdown voltage (BVCEO) of 350V and a maximum collector current of 500mA. The device provides a DC current gain (hFE) of at least 20 at 50mA collector current and 10V Vce, with a saturation voltage of 1V maximum at 50mA/5mA base current. The transition frequency is 50 MHz, making it suitable for moderate-speed switching.

Power dissipation is rated at 350mW, and the junction-to-ambient thermal resistance is 403°C/W, requiring attention to thermal management in compact designs. The operating junction temperature range is -55°C to 150°C. The transistor is qualified to AEC-Q101 standards for automotive reliability and is fully RoHS compliant, halogen-free, and lead-free.

The FMMT6517TA is packaged in a SOT-23-3 surface mount package, which is ideal for space-constrained PCB layouts. The package uses a molded plastic compound with UL 94V-0 flammability rating and matte tin plated leads for solderability. This transistor is suitable for general purpose switching, driver stages, and power management in automotive and industrial electronics.
