TIP140 NPN Power Darlington Transistor 60V 10A TO-247-3

Description

TIP140 NPN Power Darlington Transistor 60V 10A TO-247-3 The TIP140 is an NPN Darlington silicon power transistor designed for robust general-purpose amplification and low-frequency switching. Packaged in TO-247, the TIP140 integrates two transistors monolithically to deliver very high DC current gain with a single control input, making it suitable where large collector currents must be switched or amplified with modest base drive. Thanks to its Darlington pair construction and built-in base-emitter shunt resistor, the device simplifies circuit design by reducing external bias components and improving stability under load. The transistor is rated for substantial power handling when properly mounted to a heatsink, and typical on-state voltages reflect the Darlington topology’s higher saturation compared with single transistors. Mechanically available in TO-247 (the TO-247 package is the primary offering), the TIP140 targets power control roles such as motor drivers, power amplifiers, and switching regulators where a rugged, high-gain, high-current NPN device is required. Thermal and safe-operating-area graphs in the datasheet guide reliable use at elevated currents and voltages. Features: High DC current gain Min hFE = 1000 @ IC = 5.0 A, VCE = 4 V. Collector-Emitter sustaining voltage VCEO(sus) = 60 V (TIP140).
