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.
