IRFB4115 / IRF4115 Mosfet Transistor (SH) TO-220 (Class-B) (White) Code: 31805759

The IRFB4115 is a high-performance, N-Channel power MOSFET housed in a standard TO-220 package. It is widely used in high-power inverters, DC-DC converters, and motor controllers because it combines low conduction losses with fast switching capabilities.

Core Specifications

• Drain-Source Voltage :150V maximum
• Continuous Drain Current :104A at 25°C (Silicon Limited)
• On-State Resistance :11mΩ maximum (typically around 9.3mΩ)
• Maximum Power Dissipation :380W
• Gate-to-Source Voltage :± 20V maximum

Thermal & Dynamic Characteristics

• Operating Junction Temperature:-55°C to +175°C
• Pulsed Drain Current :420A
• Avalanche Ruggedness:Features improved gate, avalanche, and dynamic dv/dt ruggedness for high-stress, hard-switched environments.

Pinout Configuration (TO-220)

The IRFB4115 features a standard 3-pin through-hole configuration:

1. Gate (G):The control terminal; requires a voltage of at least 10V to fully saturate and minimize on-resistance.
2. Drain (D):The terminal where current flows out, typically connected to your load.
3. Source (S):The terminal where current flows into the transistor, typically connected to the ground or the positive voltage supply.

Common Applications

• High-efficiency synchronous rectification in Switched-Mode Power Supplies (SMPS)
• Uninterruptible Power Supplies (UPS)
• High-frequency and hard-switched power circuits
• Electric vehicle (EV) motor controllers
