概要
Equivalent
- IRFZ44N (same specs, different packaging)
- IRFZ44 (similar, slightly lower specs)
- IRFZ46N (higher current rating)
- IRFZ48N (higher voltage/current)
- STP55NF06L (similar specs, STMicro)
- FQP50N06 (Fairchild equivalent)
These are N-channel MOSFETs with comparable voltage/current ratings (~55V, ~50A). Verify datasheets for exact compatibility.
Features
- Voltage Rating: 55V drain-to-source (VDSS)
- Current Rating: 49A continuous (ID) at 25°C
- Low On-Resistance: 22.5mΩ (max) at VGS = 10V
- Fast Switching: Low gate charge (63nC) and fast rise/fall times
- Gate Drive Voltage: 4V (min threshold), 10V recommended for full enhancement
- Power Dissipation: 94W (with heatsink)
- Package: TO-220AB (through-hole, easy mounting)
- Avalanche Rated: Robust against inductive load spikes
Ideal for power switching, motor control, DC-DC converters, and high-current applications. Offers efficient performance with minimal heat generation.
Pinout
1. Gate (G): Controls the switching (typically driven by 4V–10V).
2. Drain (D): Connects to the load (handles up to 55V, 49A continuous).
3. Source (S): Ground/reference for the gate signal.
Key Features:
- VDS: 55V
- ID: 49A (continuous)
- RDS(on): 22.5mΩ (max at VGS=10V)
- Logic-Level Gate Drive: Partially enhanced at 4V.
Used in power switching, motor control, and DC-DC converters.
Application
1. Power Supplies – Switching regulators, DC-DC converters.
2. Motor Control – H-bridge circuits, PWM-driven motors.
3. LED Drivers – Efficient current control for lighting systems.
4. Automotive Systems – Relays, solenoids, and electronic control units (ECUs).
5. Inverters – Converts DC to AC in solar and UPS applications.
Its low on-resistance (RDS(on)) and high current handling (up to 49A) make it suitable for high-efficiency switching applications.
