FMMT497TA Description

Short technical summary and product information.

The FMMT497TA by Diodes Incorporated is a silicon planar NPN high voltage bipolar junction transistor designed for general purpose switching and amplification applications requiring elevated voltage handling.

 

This transistor features a collector-emitter breakdown voltage (VCEO) of 300V minimum and a continuous collector current rating of 500mA, with peak pulse current capability up to 1A. DC current gain (hFE) ranges from 80-300 at 100mA/10V test conditions, and a typical transition frequency of 75 MHz supports moderate-speed switching applications.

 

The device is supplied in a compact SOT-23-3 surface mount package with gull wing leads, making it suitable for space-constrained PCB designs. All electrical parameters are specified across an operating junction temperature range of -55°C to +150°C.

 

Switching performance is characterized with typical rise time of 126 ns and fall time of 228 ns at VCC=100V, providing predictable behavior in high voltage pulse circuits. The complementary PNP part is FMMT597.
