Qspeed Family 2 V, 2 A Common-Cathode Diode Product Summary I F(AVG) per diode 1 A V RRM 2 V Q RR (Typ at 12 C) 48.4 nc I RRM (Typ at 12 C) 3.29 A Softness t b/t a (Typ at 12 C).34 Pin Assignment General Description This device has the lowest Q RR of any 2 V Silicon diode. Its recovery characteristics increase efficiency, reduce EMI and eliminate snubbers. Applications AC/DC and DC/DC output rectification Output and freewheeling diodes Motor drive circuits DC-AC inverters Features TO-22AB LQA2T2C A1 A2 TO-22 DPAK K LQA2N2C RoHS Compliant Package uses Lead-free plating and Green mold compound Halogen free per IEC 61249-2-21. Absolute Maximum Ratings Low Q RR, Low I RRM, Low t RR High di F /dt capable (1A/ s) Soft recovery Benefits Increases efficiency Eliminates need for snubber circuits Reduces EMI filter component size and count Enables extremely fast switching Absolute maximum ratings are the values beyond which the device may be damaged or have its useful life impaired. Functional operation under these conditions is not implied.
