MPSA42 Description

Short technical summary and product information.

The UTC MPSA42 is a high voltage NPN silicon transistor designed for demanding applications such as telephone switching and general high voltage switching. It offers a maximum Collector-Emitter Voltage (VCEO) of 300V for the MPSA42 variant and 200V for the MPSA43 variant, making it suitable for circuits requiring significant voltage handling.

Key electrical characteristics include a maximum Collector Current (IC) of 500mA and a minimum DC Current Gain (hFE) of 80 at 1mA collector current. The transistor also boasts a Current Gain Bandwidth Product (fT) of 50MHz at 10mA collector current, indicating good high-frequency performance for its class.

Available in both TO-92 and SOT-89 packages, the MPSA42 supports various mounting types, including through-hole and surface mount. The datasheet specifies different power dissipation ratings for each package type, with the SOT-89 rated at 500mW and the TO-92 at 625mW at 25°C ambient temperature. Lead-free plating options are also available, indicated by an 'L' suffix in the part number.
