25N120 IGBT Power Card
High-Voltage Switching | Efficient Power Conversion | Industrial Durability
The 25N120 IGBT Card is a precision-engineered power-stage module built around 25A, 1200V N-channel IGBTs. Tailored for inverter welding machines, switch-mode power supplies, and motor-drive inverters, this board delivers low-loss switching, rapid gate response, and robust protection under heavy-load conditions.
🔧 Key Features:
-
⚡ 25N120 IGBTs – Two or more matched 25 A/1200 V devices arranged in half-bridge or full-bridge topology for flexible power conversion
-
🌡️ Low Thermal Resistance – Wide copper traces and integrated heatsink mounting pads for efficient heat dissipation
-
🔒 Integrated Gate Drivers – On-board driver circuitry with under-voltage lockout and configurable dead-time for clean switching edges
-
🛡️ Protection Circuits – Built-in over-current (OCP), over-voltage (OVP), and thermal shutdown safeguards
-
🔌 Heavy-Duty Terminals – Screw or bus-bar connections for DC bus, load output, and gate signals
-
🧲 EMI Mitigation – Snubber networks and input/output filter components reduce electromagnetic interference
