LQA08TC600 Qspeed™ Family 600 V, 8 A Q-Series PFC Diode Product Summary IF(AVG) VRRM QRR (Typ at 125 °C) IRRM (Typ at 125 °C) Softness tb/ta (Typ at 125 °C) 8 600 36 2 1.3 General Description A V nC A This device has the lowest QRR of any 600 V Silicon diode. Its recovery characteristics increase efficiency, reduce EMI and eliminate snubbers. Applications • Power Factor Correction (PFC) Boost Diode • Motor drive circuits • DC-AC Inverters Pin Assignment Features NC • Low QRR, Low IRRM, Low tRR • High dIF/dt capable (1000A/µs) • Soft recovery NC C A Benefits A • Increases efficiency • Eliminates need for snubber circuits • Reduces EMI filter component size & count • Enables extremely fast switching • C TO-220AC RoHS Compliant Package uses Lead-free plating and Green mold compound. Halogen free per IEC 61249-2-21. Absolute Maximum Ratings 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.
