The FMMT555A is a PNP high-voltage bipolar transistor manufactured by Diotec and available through Supreme Components International, an authorized distributor of electronic components. This transistor is housed in a small SOT-23 package, making it ideal for applications where board space is limited. The FMMT555A features a collector-emitter voltage (Vceo) of -500V and a continuous collector current (Ic) of -0.2A. This makes it suitable for high-voltage switching and amplification applications. Its high voltage capability makes it a reliable choice for demanding circuits. Consider the FMMT555A for your next high-voltage design requiring a compact and efficient transistor.
