MMBT3646 Description

Short technical summary and product information.

The MMBT3646 is an NPN bipolar junction transistor (BJT) designed for various switching applications. It offers a collector-emitter voltage (VCEO) of 15V and a continuous collector current (IC) of up to 300mA.

 

Key electrical characteristics include a maximum collector-emitter saturation voltage (VCE(sat)) of 0.5V at 300mA collector current and 30mA base current. The DC current gain (hFE) ranges from a minimum of 15 at 300mA collector current to 1V collector-emitter voltage, up to 30 at 30mA collector current and 400mV collector-emitter voltage.

 

This transistor is housed in a compact SOT-23-3 surface mount package, making it suitable for space-constrained designs. The operating temperature range is -55°C to 150°C (TJ), and it has a total power dissipation of 625mW at 25°C ambient temperature.

 

Switching characteristics include a typical turn-on time of 18ns and a turn-off time of 28ns, with delay, rise, fall, and storage times also specified. The thermal resistance junction-to-case is 83.3°C/W.
