2SB1257 Overview
In this device, the DC current gain is 2000 @ 3A 4V, which is calculated by taking the ratio of the base current to collector current and dividing transistor by two.Saturation of VCE means Ic is at its maximum value (saturated), and VCE saturation (Max) is 1.5V @ 6mA, 3A.200MHz is present in the transition frequency.Supplier device package TO-220F comes with the product.Voltage of maximal collector-emitter is set to 60 V.The device exhibits a collector-emitter breakdown at 60 V.Maximum collector currents can be below 4A volts.
2SB1257 Features
the DC current gain for this device is 2000 @ 3A 4V
