LQA10N150C

Diode Arrays Overview

The LQA10N150C is a Qspeed™ family common-cathode diode from Power Integrations, housed in a TO-252 DPAK package. It features a peak repetitive reverse voltage (VRRM) of 150 V and an average forward current per diode of 5 A at TJ = 150 °C. The device exhibits a typical reverse recovery charge (QRR) of 21.4 nC and a maximum reverse recovery current (IRRM) of 1.41 A at 125 °C. Its softness factor (tb/ta) is typically 0.59 at the same temperature.
