2SAR340PT100P ROHM Single

The 2SAR340PT100P from ROHM is a high-voltage PNP bipolar transistor designed for low-current switching and amplification. For selection, its key feature is a 400V collector-emitter breakdown voltage paired with a 100mA continuous collector current, making it ideal for high-voltage, low-power circuits. The low saturation voltage of 400mV at 20mA ensures efficient switching with minimal power loss. A minimum DC current gain of 82 provides reliable drive capability, while the 500mW power dissipation suits compact designs. In application, it excels in high-voltage switching regulators, small signal amplifiers in industrial controls, and relay drivers for smart meters. Its high voltage rating also makes it perfect for telephone ring generators, strobe flash trigger circuits, and CRT display horizontal deflection drivers. The compact MPT3 surface-mount package enables space-saving PCB layouts, while 150°C junction temperature ensures reliable operation in thermally demanding environments.
