## Summary description

NPN Darlington transistor in a TO-220AB package rated for 100 V collector-emitter voltage and 8 A current. Designed for power switching and amplification in electronic circuits, suitable for motor control, power supplies, and relay drivers. Through-hole TO-220AB format allows heatsinking for improved thermal management and reliable operation in medium-power applications.

## Long description

NPN Darlington transistor in a TO-220AB through-hole package rated for 100 V collector-emitter voltage and 8 A continuous current. This compatible power transistor integrates a Darlington pair configuration to provide high current gain, making it suitable for switching and amplification tasks in medium-power electronic circuits. The TO-220AB format includes a metal tab for attaching a heatsink, enabling improved thermal management for reliable operation under load.
Advantages
The Darlington arrangement delivers high current amplification with minimal base drive, enabling control of larger loads from low-power control signals. The TO-220AB through-hole package facilitates solid PCB mounting and effective heatsinking to dissipate heat during sustained operation. Rated for up to 100 V and 8 A, the device balances voltage and current capability for a variety of power electronics uses while maintaining straightforward integration into common designs.
Suitable for
 Motor drivers and small DC motor control
 Switching power supplies and regulators
 Relay and solenoid drivers
 Audio amplifiers and pre-drivers requiring high current gain
 General-purpose power switching and load control

 Maximum continuous collector current (Ic): 8 A
 Configuration: Complementary internal transistor pair for high gain
 Cooling: Heatsink recommended for high dissipation applications
 Mounting: PCB through-hole with screw-mountable tab
How to use
Install the transistor in a through-hole PCB footprint matching the TO-220AB pinout, and secure the metal tab to a heatsink or chassis when operating at elevated currents or power dissipation. Ensure correct pin connections for collector, base(s), and emitter according to the circuit design. Drive the base with appropriate biasing and base resistors as required to limit input current and control saturation. Observe safe operating area limits, provide proper decoupling on power rails, and include a flyback diode when driving inductive loads such as motors, relays, or solenoids.
Usage recommendations
For reliable operation, attach an adequately sized heatsink to the TO-220AB tab when operating near the 8 A rating or in confined thermal environments. Use base resistors or driver stages to limit base current and avoid exceeding the device's safe operating area. When switching inductive loads, place a fast flyback diode or snubber across the load and ensure proper PCB layout to minimize thermal hotspots and noise coupling.
