Component

Darlington ArrayHigh Current DriverRelay Driver

The TM2803L is an 8-channel Darlington transistor array designed for high-voltage, high-current switching applications.

Best for

  • Relay driving
  • Stepper motor control
  • LED lighting arrays

Avoid if

  • High-speed switching applications (limited by Darlington switching times)
  • Applications requiring low saturation voltage (Darlington pairs have higher Vce(sat) than standard transistors)

Check before use

  • Thermal management for high-duty cycle operation
  • Inductive load flyback diode connection
