LESHAN RADIO COMPANY, LTD. Bias Resistor Transistor PNP Silicon Surface Mount Transistor with Monolithic Bias Resistor Network • LDTA144VET1G 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 VCC VI IO IC(Max.) −50 −40 to +15 V V −30 −100 mA Pd 200 mW Tj Tstg 150 −55 to +150 °C °C Supply voltage Input voltage Output current Power dissipation Junction temperature Storage temperature R1 3 COLLECTOR R2 2 EMITTER DEVICE MARKING AND RESISTOR VALUES Device Marking R1 (K) R2 (K) Shipping LDTA144VET1G L9 47 10 3000/Tape & Reel LDTA144VET3G L9 47 10 8000/Tape & Reel zElectrical characteristics (Ta=25°C) Parameter Input voltage Output voltage Input current Output current DC current gain Input resistance Resistance ratio Transition frequency Symbol Min.
