A compact, high‑performance MOSFET for AEG gearboxes designed to enhance trigger responsiveness and protect your switching contacts.
Product Features:

• Supports up to 30V input voltage and 200 A maximum current
• Ultra-low internal resistance (≈0.00095 Ω in parallel configuration) for minimal voltage drop and heat generation
• Dual MOSFET driver design to deliver responsive trigger action
• Built-in protection against back-electromotive force (BEMF) to safeguard the MOSFET from inductive voltage spikes
• Compact form factor (≈30 × 14 × 4.7 mm) for easy fitment in most gearboxes
• Supplied heat-shrink tubing for insulation and neat installation

The Xcortech XET304u is a robust yet compact MOSFET unit built to upgrade airsoft AEGs by improving electrical efficiency, trigger response, and protecting against back‑EMF damage. It supports up to 30V input voltage and 200A continuous current, making it suitable for a wide range of setups, including high‑voltage battery configurations. Featuring ultra‑low internal resistance and built‑in circuit protection, the XET304u helps reduce heat, preserve battery life, and prevent contact arcing. Its compact footprint and included heat‑shrink tubing make it relatively easy to install without adding appreciable bulk inside the gearbox.
