STP6N25 STP6N25FI is a power MOS transistor from Dinghao. It is a N-channel enhancement mode and has a typical RDS(on) of 0.7Ω. The product is used in high speed switching, uninterruptible power supply (UPS), motor control, audio amplifiers, industrial actuators, DC-DC and DC-AC converters for telecom, industrial and consumer environments, and is particularly suitable for electronic fluorescent lamp ballasts.
The STP6N25 is a 250 V N‑channel power MOSFET designed for high‑speed switching applications such as UPS systems, motor control, audio amplifiers, industrial actuators and DC‑DC/DC‑AC converters. It is offered in TO‑220 and ISOWATT220 (isolated) packages and features avalanche‑tested robustness.
Key parameters include a continuous drain current of 4 A at 25 °C, a pulsed current rating of 24 A, a total power dissipation of up to 70 W (TO‑220) and typical on‑resistance of 0.7 Ω. Thermal resistance values, gate charge, and capacitance data are also provided for detailed design work.
