Features & Applications

Vishay has set an important precedent in MOSFET technology through the IRF634 series. This cost-effective technology enhances system performance in the areas of both efficiency and reliability. Renown for it’s fast switching speed, this MOSFET series provides an excellent solution in both high-power and high-current applications, all the while optimizing switching performance.

The ruggedness that this technology offers, combined with its low package cost, has made the MOSFET universally preferred for all commercial-industrial applications. The robust design is ideal for applications that require large amounts of power.

By delivering superior performance, in its MOSFET series, backed by higher efficiency, lower conduction losses and greater power density, Vishay offers unique technological solutions. Ideal for AC-DC servers, laptop adapters, and desktop power supplies, Vishay strives to meet ongoing customer demand backed by industry-leading quality.

Perfect for both commercial and industrial applications, the IRF634 (this part is lead free) has the capacity to operate at 250V within an operating temperature range of 150 degrees C. The net result translates to a lower resistance (RDS (on) = 0.45 Ohms). Repetitively avalanche rated, the IRF634 is able to reduce power dissipation levels to approximately 50 watts. The IRF634 provides high speed, robust efficiency combined with low on-resistance and cost-effectiveness all in a TO-220 package format.
