LESHAN RADIO COMPANY, LTD. Bias Resistor Transistor NPN Silicon Surface Mount Transistor with Monolithic Bias Resistor Network • LDTC144EET1G 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 Limits Symbol VCC 50 V Input voltage VIN −10 to +40 V IO 30 IC(Max.) 100 Output current 3 COLLECTOR R2 2 EMITTER Unit Supply voltage R1 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 LDTC144EET1G N5 47 47 3000/Tape & Reel LDTC144EET3G N5 47 47 10000/Tape & Reel zElectrical characteristics (Ta=25°C) Parameter Input voltage Output voltage Input current Symbol Min.
