FFB3946 Description

Short technical summary and product information.

The FFB3946 is a complementary NPN/PNP bipolar transistor array designed for general-purpose switching and amplification applications. Manufactured by ON Semiconductor, this device integrates two transistors in a single surface-mount package, offering space savings and matched performance.

 

Key electrical specifications include a collector-emitter breakdown voltage of 40V, a maximum collector current of 0.2A, and a DC current gain (hFE) of 100 minimum at 10mA collector current. The transition frequency is 200 MHz, suitable for low-frequency switching and signal amplification. Maximum power dissipation is 300 mW, with an operating temperature range of -55°C to 150°C.

 

The part is housed in a compact 6-pin SC-88 (SC-70-6) package, also known as SOT-363, with a surface-mount mounting type. The device is RoHS3 compliant, REACH unaffected, and has an MSL of 1 (unlimited). This transistor array is ideal for applications requiring matched NPN and PNP characteristics in a small footprint, such as audio amplifiers, driver stages, and logic level shifting.
