Features

The MJD31C is an NPN Darlington transistor with the following key features:
- High Current Gain (hFE): Typically 1000, making it suitable for low-power amplification and switching.
- Collector Current (IC): Up to 3A, handling moderate loads.
- Collector-Emitter Voltage (VCEO): 100V, supporting medium-voltage applications.
- Power Dissipation (Ptot): 30W, with proper heat sinking.
- Darlington Pair Configuration: Enhances sensitivity for small input signals.
- TO-252 (DPAK) Package: Compact and surface-mountable.
Commonly used in relay drivers, motor control, and power regulators. Requires a heat sink for high-current operation.
