6 / 14 page IR4301,IR4311 6 www.irf.com © 2012 International Rectifier December 5, 2012 †††† Per MOSFET ††††† Repetitive rating, pulse width limited by max. junction temperature Recommended Operating Conditions For proper operation, the device should be used within the recommended conditions below. The Vss and Vs offset ratings are tested with supplies biased at COM=VN, VAA-VSS=9.6V, VCC=12V and VB-VS=12V. All voltage parameters are absolute voltages referenced to COM; all currents are defined positive into any lead. Symbol Definition Min. Max.
