FMMT549
PNP Low Saturation Transistor
Features
• ThIs device is designed with high current gain and low saturation voltage
with collector currents up to 2A continuous.
• Sourced from process PB.
Absolute Maximum Ratings* T
A
= 25°C unless otherwise noted
* These ratings are limiting values above which the serviceability of any semiconductor device may be impaired.
NOTES:
1)These ratings are based on a maximum junction temperature of 150 degrees C.
2)These are steady state limits. The factory should be consulted on applications involving pulsed or low duty cycle
operations
Thermal Characteristics*
* Device mounted on FR-4 PCB 4.5” X 5”, mounting pad 0.02 in
2
of 2 oz copper.
