5 / 16 page IRS20957S www.irf.com © 2008 International Rectifier 5 Absolute Maximum Ratings Absolute Maximum Ratings indicate sustained limits beyond which damage to the device may occur. All voltage parameters are absolute voltages referenced to VSS; all currents are defined positive into any lead. The Thermal Resistance and Power Dissipation ratings are measured under board mounted and still air conditions. Symbol Definition Min. Max. Units VB High side floating supply voltage -0.3 215 VS High side floating supply voltage † VB-15 VB+0.3 VHO High side floating output voltage Vs-0.3 VB+0.3 VCSH CSH pin input voltage Vs-0.3 VB+0.3 VCC Low side fixed supply voltage † -0.3 20 VLO Low side output voltage -0.3 VCC +0.3 VDD Floating input supply voltage -0.3 210 VSS Floating input supply voltage † (See IDDZ) VDD+0.3 VIN PWM input voltage VSS -0.3 VDD+0.3 VCSD CSD pin input voltage VSS -0.3 VDD+0.3 VDT DT pin input voltage -0.3 VCC +0.3 VOCSET OCSET pin input voltage -0.3 VCC +0.3 VREF VREF pin voltage -0.3 VCC +0.3 V IDDZ Floating input supply zener clamp current † - 10 ICCZ Low side supply zener clamp current † - 10 IBSZ Floating supply zener clamp current † - 10 IOREF Reference output current - 5 mA d VS /dt Allowable VS voltage slew rate - 50 d VSS /dt Allowable VSS voltage slew rate †† - 50 V/ns d VSS /dt Allowable VSS voltage slew rate upon power-up ††† - 50 V/ms Pd Maximum power dissipation - 1.0 W RthJA Thermal resistance, Junction to ambient - 115 °C/W TJ Junction Temperature - 150 TS Storage Temperature -55 150 TL Lead temperature (Soldering, 10 seconds) - 300 °C † VDD - VSS, VCC -COM and VB - VS contain internal shunt zener diodes. Please note that the voltage ratings of these can be limited by the clamping current. †† For the rising and falling edges of step signal of 10V. Vss=15V to 200V. ††† Vss ramps up from 0V to 200V. |
