FMMT634TA Description

Short technical summary and product information.

The FMMT634TA is a 100V NPN Darlington transistor manufactured by Diodes Incorporated. It features a maximum collector-emitter voltage of 100V, continuous collector current of 900mA, and peak pulse current capability of 5A. The device offers a high DC current gain of at least 20000 at 100mA and 5V, ensuring low base drive requirements. Typical transition frequency is 140MHz. The transistor is rated for operation from -55°C to 150°C junction temperature.

 

The part is housed in a surface-mount SOT-23-3 package with matte tin plated leads. It is fully RoHS compliant, halogen and antimony free, and qualified to AEC-Q101 standards for high reliability. The complementary PNP type is FMMT734. Typical applications include lamp, relay, and solenoid driving. The device is supplied in 7-inch reels with 3000 units per reel.
