ROHM 2SA1727, 2SA1776, 2SA1812 Schematic [ru]
2SA1812 / 2SA1727 / 2SA1776
Transistors
High-voltage Switching Transistor
( 400V, 0.5A)
2SA1812 / 2SA1727 / 2SA1776
Features
1) High breakdown voltage, BVCEO= 400V.
2) Low saturation voltage, typically VCE (sat) = 0.3V at IC / IB = 100mA / 10mA.
3) High switching speed, typically tf : 1 s at IC = 100mA.
4) Wide SOA (safe operating area).
