LDTC143EWT1G

LESHAN RADIO COMPANY, LTD. Bias Resistor Transistor NPN Silicon Surface Mount Transistor with Monolithic Bias Resistor Network LDTC143EWT1G Applications Inverter, Interface, Driver 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. We declare that the material of product compliance with RoHS requirements. zAbsolute maximum ratings (Ta=25°C) Parameter Supply voltage Input voltage Output current Power dissipation Junction temperature Storage temperature Symbol VCC VIN IC PD Tj Tstg Limits 50 −10 to +10 100 200 150 −55 to +150 Unit V V mA mW C C 3 1 2 SOT–323 (SC–70) 1 BASE R1 R2 3 COLLECTOR 2 EMITTER DEVICE MARKING AND RESISTOR VALUES Device Marking R1 (K) R2 (K) Shipping LDTC143EWT1G 8J 4.7 4.7 3000/Tape & Reel LDTC143EWT3G 8J 4.7 4.7 10000/Tape & Reel zElectrical characteristics (Ta=25°C) Parameter Symbol Min.
