• Pulsed Drain Current (IDM): 630A

• On-Resistance (RDS(on)): ~2.0 mΩ (Max) at VGS = 10V (Key feature – very low resistance)

• Gate Threshold Voltage (VGS(th)): 2V – 4V (Standard logic-level compatible)

• Package: TO-220 (Through-Hole, with metal tab for heatsinking)

• Pinout (TO-220, front view, tabs facing you):

  1. Gate (G)

  2. Drain (D) (connected to the metal tab)

  3. Source (S)

• Total Gate Charge (Qg): ~130 nC (Typical)

• Operating Junction Temperature: -55°C to +175°C

• Quantity: 2 pieces

⚙️ Key Features:

• Extremely Low RDS(on): The ~2.0 mΩ on-resistance enables very high efficiency by minimizing voltage drop and heat generation during conduction.

• High Current Capability: Suitable for demanding applications like high-power motor control, solenoid/actuator drivers, and high-current power switches.

• Logic-Level Gate: Can be driven directly by 5V microcontroller GPIO pins (like Arduino, Raspberry Pi) for convenient digital control.

• Fast Switching Speed: Suitable for PWM (Pulse Width Modulation) applications up to moderate frequencies (tens to low hundreds of kHz).

• TO-220 Package: Easy to mount and heatsink for high-power applications.

📦 Typical Applications:

• High-Current DC Motor Control: H-Bridge drivers for robots, electric vehicles, and industrial equipment.

• Power Switching: Solid-state relays, high-power LED dimmers, and battery management systems (BMS).

• DC-DC Converters: As the main switch in high-current buck/boost converters and inverters.

• Solenoid/Valve/Actuator Drivers: For industrial automation and automotive systems.

• Audio Amplifiers: In the output stage of high-power class-D amplifiers.

🔧 Critical Usage & Heatsinking Guide:

1. Gate Driving: Always use a gate driver IC (e.g., TC4427, IR2110) or at least a gate resistor (10Ω – 100Ω) when switching at high speeds or with high currents to prevent oscillation and ensure fast transitions.

2. Heatsinking is MANDATORY: The TO-220 tab is electrically connected to the Drain. Use a thermally conductive but electrically insulating pad (mica or silicone) and a heatsink for any significant continuous current (>5-10A). Secure with an insulating shoulder washer.

3. Anti-Parallel Diode: This MOSFET has no internal body diode (check datasheet to confirm). For inductive loads (motors, solenoids), you MUST add an external fast recovery flyback diode (e.g., UF4007, MUR460) across the load to protect the MOSFET from voltage spikes.

4. Absolute Maximums: The 210A rating is a theoretical maximum under perfect cooling. Real-world continuous current is limited by your heatsink’s ability to keep the junction temperature below 150°C. A conservative design might limit continuous current to 30A-60A with a good heatsink.

⚠️ Important Safety & Design Warnings:

• Static Sensitive (ESD): Handle with care. Store in anti-static foam.

• Smoke Warning: Without proper heatsinking and gate driving, this MOSFET can fail catastrophically (short circuit) in microseconds, potentially damaging your power supply and load.

• Verify Pinout: Always double-check the pinout with a multimeter in diode-test mode before wiring.

• Realistic Current: Do not assume you can run 210A continuously. Thermal design is paramount.
