In addition to the well established characteristics of the IRC250 200V 0.085Q 29A HEXFETs, they provide an accurate fraction of the drain cur- rent as feedback parameters for contro! and/or protection. Fields of applications include: current mode motor control; power Features: Las supplies using flyback or push pull topology; uninterruptible = power systems; instrumentation; solid state relays; CRT deflec- I +2.5% Sensing Accuracy tion, solenoid and lamp drive circuits. The HEXFET technology is the key to International Rectifier's Ml Repetitive Avalanche Ratings advanced line of power MOSFET transistors. The efficient \ , geometry and unique processing of the HEXFET design achieve Mi Dynamic dv/dt Rating very low on-state resistance combined with high transconduc- tance and great device ruggedness. @ Simple Drive Requirements CASE STYLE AND DIMENSIONS basis | rere a1 une 3.08 (0200) 480 (0.185) Similar to JEDEC Outline TO-204AE (Modified TO-3) Dimensions in Millimeters and (Inches) E-47IRC250 Device ALE OD i 4assuS2 gogad4d 3 i INTERNATIONAL RECTIFIER T-39-13 Shown below are two typical circuit applications of HEXSense power MOSFETs.
