2SA2049
Transistor
1/3
Medium power transistor (−30V, −2.0A)
2SA2049


!Features
1) High speed switching. (Tf : Typ. : 20ns at IC =
−
2.0A)
2) Low saturation voltage, typically
(Typ. : −250mV at IC =
−
1.0A, IB =
−
100mA)
3) Strong discharge power for inductive load and
capacitance load.
4) Complements the 2SC5731
