LQA30T300 Qspeed™ Family 300 V, 30 A Q-Series Diode Product Summary IF(AVG) VRRM QRR (Typ at 125 °C) IRRM (Typ at 125 °C) Softness tb/ta (Typ at 125 °C) 30 300 53 2.85 0.6 A V nC A General Description This device has the lowest QRR of any 300V Silicon diode. Its recovery characteristics increase efficiency, reduce EMI and eliminate snubbers. Applications Pin Assignment • AC/DC and DC/DC output rectification • Output & freewheeling diodes • Motor control drive circuits • Uninterruptible Power Supply (UPS) inverters Features • Low QRR, Low IRRM, Low tRR • High dIF/dt capable (1000A/µs) • Soft recovery A C Benefits • Increases efficiency • Eliminates need for snubber circuits • Reduces EMI filter component size & count • Enables extremely fast switching 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.
