The FMA4A is a dual digital transistor with built-in bias resistors, packaged in an SOT-25 case, designed for applications such as inverters, interfaces, and drivers. It contains two PNP transistors with a collector-emitter voltage rating of -50 V, a collector current rating of -100 mA, and a total power dissipation of 300 mW. Each transistor element must not exceed 200 mW. The device has a DC current gain (hFE) ranging from 100 to 600 at 1 mA collector current, an input resistance of 7 to 13 kΩ, and a collector-emitter saturation voltage of up to 300 mV. It operates from -55°C to +150°C junction temperature and meets RoHS standards. The package dimensions are specified for surface-mount assembly.
Devices integrating two transistors are available in ultra-compact packages, suitable for various applications such as pre-amplifier differential amplification circuits, high-frequency oscillators, driver ICs and so forth.
