The IRFP260M is HeroMicro an N-channel enhancement-mode power MOSFET fabricated using advanced trench technology, featuring ultra-low on-resistance (RDS(ON)), high current capability, and excellent switching performance. Designed for high-power, high-efficiency applications, it is ideal for switch-mode power supplies (SMPS), motor drives, inverters, uninterruptible power supplies (UPS), and hard-switching circuits. Housed in a TO-247 package, it offers superior heat dissipation and is a core component in industrial and power electronics systems.

2. Key Usage Guidelines
(1) Gate Drive Design
Use VGS = 10 V for full enhancement and minimum RDS(ON).
Input capacitance (Ciss) is 6200 pF, and reverse transfer capacitance (Crss) is 460 pF; be mindful of Miller effect in high-frequency applications.
Low total gate charge enables fast switching with minimal drive loss.
Use a dedicated MOSFET driver or low gate resistance (e.g., 6–10 Ω) to optimize switching speed and reduce losses.
(2) Thermal Management
RθJC = 0.53 °C/W indicates excellent thermal conductivity between junction and case.
Maximum power dissipation is 285 W, but requires an efficient heatsink to keep case temperature (TC) below 100°C.
Power loss consists of conduction loss (ID² × RDS(ON)) and switching loss. In high-frequency applications, switching loss dominates; optimize the gate drive circuit accordingly.
Apply thermal grease between the heatsink and device, and use a spring washer to ensure uniform pressure.
(3) Body Diode Characteristics
Integrated body diode supports robust freewheeling:
Source-Drain Forward Voltage (VSD): ≤ 1.2 V (@ IS = 90 A, VGS = 0 V)
Reverse Recovery Time (trr): 78 ns (@ IF = 90 A, di/dt = 100 A/μs)
Reverse Recovery Charge (Qrr): 51 nC
The body diode can provide a freewheeling path in inductive loads, but its reverse recovery may cause voltage spikes and EMI. Consider adding a fast recovery diode or RC snubber if necessary.
(4) Safe Operating Area (SOA)
Refer to the SOA curve (Figure 8) to ensure operation remains within thermal and current limits.
Avoid switching high currents at high voltages to prevent secondary breakdown.
(5) Electrostatic Discharge (ESD) Protection
MOSFETs are ESD-sensitive. Use ESD-safe handling procedures during assembly, soldering, and testing.
3. Typical Applications
High-power SMPS
Motor drives and H-bridge circuits
Solar inverters and UPS systems
Hard-switching and high-frequency circuits
Battery Management Systems (BMS)
