Thinkpad4by3/chibitron
Electrostatic CRT driver designed from the ground up for performance, versatility and ease-of-manufacturability

The FMMT558TA is a bipolar made by Diodes Incorporated in a SOT-23 package with 3 pins. -55℃~+150℃ 1 PNP 100 100nA 150mA 400V 500mV 500mW 50MHz 7V PNP SOT-23 Bipolar (BJT) ROHS.
PCBKit's library has its KiCad symbol (Pinmap_Generic:Q_PNP_1B_2E_3C, from PCBKit's generic symbols) and its footprint (Package_TO_SOT_SMD:SOT-23, from KiCad's library), ready for a KiCad board. 486 are in stock at JLCPCB (part C74606). 3 open-source boards in 1 repository on GitHub use it.
