Toshiba shrinks 150W audio transistor

Toshiba has shrunk the package size of its transistor for the output stage of 150W audio systems.

The 2SA1943N and 2SC5200N transistors are in effective smaller versions the the existing 2SA1943 and 2SC5200 devices in a TO-3P(N) package instead of the previous TO-3P(L) package.

The supplier claims the package power is still 150W.

The 2SA1943N transistor has a maximum collector-emitter voltage Vceo rating of -230V and continuous collector current Ic rating of -15A, while the 2SC5200N has a maximum Vceo of 230V and an Ic of 15A.

The minimum DC current gain is 80 at h(FE1) (Vce = -5V and Ic = -1A) and 35 at h(FE2) (Vce = -5V and Ic = -7A).

Both devices achieve a typical transition frequency of 30MHz.

The TO-3P(N) package measures 15.9 mm by 40.5 mm by 4.8 mm.
