MJD122 100V 8A NPN Power Transistor | TO-252 Package | WXDH

MJD122 NPN Darlington Power Transistor | 100V 8A | TO-252 (DPAK) Package | WXDH

The MJD122 is a high-performance NPN Darlington power transistor from WXDH, designed for general-purpose amplification and low-speed switching applications. With a collector-emitter voltage rating of 100V and a collector current up to 8A, it delivers reliable performance in demanding electronic circuits.

Engineered in a TO-252 (DPAK) surface-mount package, the MJD122 offers excellent thermal stability, compact design, and ease of integration into modern PCB layouts. It features a high DC current gain (hFE up to 2500 at IC = 4A) and built-in base-emitter shunt resistors, ensuring stable operation with simplified circuit design.

This device serves as a surface-mount replacement for popular Darlington transistors such as the TIP120–TIP122 series, TIP125–TIP127 series, and 2N6040–2N6045 series, making it a versatile choice for designers.

Key Features:

• Voltage Rating: 100V

• Current Rating: 8A

• High DC Current Gain: hFE ≈ 2500 (typical @ 4A)

• Low-speed switching & general amplifier applications

• Compact TO-252 (DPAK) SMD package for surface mounting

• Complementary pairs available for simplified circuit design

Ideal for consumer electronics, motor drivers, relay drivers, and power amplifier circuits, the MJD122 ensures efficient switching, high gain, and long-term reliability.
