MMSTA42-7-F Description

Short technical summary and product information.

The MMSTA42-7-F from Diodes Incorporated is an NPN epitaxial planar die construction transistor suitable for low power amplification and switching applications. It offers a high Collector-Emitter Voltage (VCEO) of 300V and a maximum Collector Current (IC) of 200mA, with a power dissipation of 200mW.

 

This device is housed in an ultra-small SOT-323 surface mount package, making it ideal for space-constrained designs. The operating temperature range is -55°C to 150°C. Electrical characteristics include a DC Current Gain (hFE) of 40 minimum at 30mA and 10V, and a Collector-Emitter Saturation Voltage (VCE(SAT)) of 500mV maximum at 2mA/20mA. The current gain-bandwidth product (fT) is 50MHz.

 

The MMSTA42-7-F is lead-free and RoHS compliant. Its complementary PNP type is available as MMSTA92. The transistor is designed for easy soldering and is suitable for various electronic circuits requiring small signal amplification.
