Maximum ratings applied to the device are individual stress limit values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied, damage may occur and reliability may be affected. 1. VDRM and VRRM for all types can be applied on a continuous basis. Ratings apply for zero or negative gate voltage; however, positive gate voltage shall not be applied concurrent with negative potential on the anode. Blocking voltages shall not be tested with a constant current source such that the voltage ratings of the devices are exceeded. *For additional information on our Pb−Free strategy and soldering details, please download the ON Semiconductor Soldering and Mounting Techniques Reference Manual, SOLDERRM/D. © Semiconductor Components Industries, LLC, 2005 November, 2005 − Rev. 4 4 V 1 2 TO−220AB CASE 221A−07 STYLE 3 3 A Y WW MCR218x G AKA AY WW MCR218x−G AKA = Assembly Location = Year = Work Week = Device Code x = 2, 4 or 6 = Pb−Free Package = Diode Polarity ORDERING INFORMATION Device Package Shipping MCR218−2 TO220AB 500 Units/Bulk MCR218−2G TO220AB (Pb−Free) 500 Units/Bulk MCR218−4 TO220AB 500 Units/Bulk MCR218−4G TO220AB (Pb−Free) 500 Units/Bulk MCR218−6 TO220AB 500 Units/Bulk MCR218−6G TO220AB (Pb−Free) 500 Units/Bulk Preferred devices are recommended choices for future use and best overall value.
