FCX493TA Description

Short technical summary and product information.

The FCX493TA is a 100V NPN medium power transistor designed for general-purpose switching and amplification. It offers a continuous collector current of 1A and a peak pulse current of 2A.

 

Key electrical specifications include a minimum DC current gain (hFE) of 100 at 250mA and 10V, a low saturation voltage of less than 300mV at 250mA, and a transition frequency of 150MHz. The device is capable of dissipating up to 1W when mounted on a standard FR4 PCB.

 

The transistor is supplied in a surface-mount SOT89 package (TO-243AA) with gull wing leads and matte tin finish. It is RoHS compliant, lead-free, and halogen-free. The moisture sensitivity level is MSL 1, allowing unlimited floor life.

 

Typical applications include load management, solenoid and relay drivers, and DC-DC converter circuits. The complementary PNP type is FCX593.
