LESHAN RADIO COMPANY, LTD. Bias Resistor Transistor NPN Silicon Surface Mount Transistor with Monolithic Bias Resistor Network • LDTC123YET1G Applications Inverter, Interface, Driver • 3 Features 1) Built-in bias resistors enable the configuration of an inverter circuit without connecting external input resistors (see equivalent circuit). 2) The bias resistors consist of thin-film resistors with complete isolation to allow positive biasing of the input. They also have the advantage of almost completely eliminating parasitic effects. 3) Only the on/off conditions need to be set for operation, making the device design easy. • 1 2 SC-89 We declare that the material of product compliance with RoHS requirements. 1 BASE zAbsolute maximum ratings (Ta=25°C) Parameter Symbol Limits Unit Supply voltage VCC 50 V Input voltage VIN −5 to +12 V IO 100 IC(Max.) 100 Output current R1 3 COLLECTOR R2 2 EMITTER mA Power dissipation Pd 200 mW Junction temperature Tj 150 °C Storage temperature Tstg −55 to +150 °C DEVICE MARKING AND RESISTOR VALUES Device Marking R1 (K) R2 (K) Shipping LDTC123YET1G N8 2.2 10 3000/Tape & Reel LDTC123YET3G N8 2.2 10 10000/Tape & Reel zElectrical characteristics (Ta=25°C) Parameter Input voltage Output voltage Typ.
