Triode/MOS tube/transistor/module

2SA1593/2SC4135 is a bipolar transistor, (-)100V, (-)2A, low saturation voltage, (PNP)NPN single TP/TP-FA for high voltage switching applications.

This family of digital transistors is intended to replace a device and its external resistor bias network. The Bias Resistor Transistor (BRT) consists of a transistor and a monolithic bias network consisting of two resistors; a series base resistor and a base emitter resistor. The BRT eliminates the need for these separate components, which are integrated into a single device. Using BRT can reduce system cost and save board space.
