IRFB18N50KPBF Description

Short technical summary and product information.

The IRFB18N50KPBF is an N-Channel power MOSFET from Vishay Dale with a drain-source voltage rating of 500V and continuous drain current of 17A at 25°C case temperature. It features a low typical on-resistance of 260mOhm at 10V gate drive and a maximum gate charge of 120nC, enabling efficient high-frequency switching in switch mode power supplies (SMPS) and other hard-switched applications. The device is housed in a TO-220AB through-hole package (TO-220-3 case) and supports a junction temperature range of -55°C to 150°C. It also offers single pulse avalanche energy of 370mJ, indicating ruggedness for demanding environments. Fully characterized capacitance and avalanche ratings make it suitable for high-speed power switching and uninterruptible power supply circuits.
