LESHAN RADIO COMPANY, LTD.
Bias Resistor Transistor
NPN Silicon Surface Mount Transistor
with Monolithic Bias Resistor Network
LDTDG12GPWT1G
zApplications
Driver
zFeatures
1) High hFE.
300 (Min.) (VCE / IC=2V / 0.5A)
2) Low saturation voltage,
(VCE(sat)=0.4V at IC / IB=500mA / 5mA)
3) Built-in zener diode gives strong protection against
reverse surge by L- load (an inductive load).
We declare that the material of product compliance with
RoHS requirements.
