LQA40T200C

Diode Arrays Overview

The LQA40T200C is a common-cathode diode from the Qspeed family, rated for 200 V peak repetitive reverse voltage and 40 A average forward current per device. It features low reverse recovery charge (QRR) of 61 nC at 125 °C and low reverse recovery current (IRRM). The component supports high dIF/dt switching up to 1000 A/µs with soft recovery characteristics. Operating junction temperature ranges from -55 °C to 150 °C. Available in TO-220AB packages.

Diode Arrays Feature Summary

• Low QRR, Low IRRM, and Low tRR
• High dIF/dt capable (1000A/µs)
• Soft recovery

Diode Arrays Applications

• AC/DC and DC/DC output rectification
• Output and freewheeling diodes
• Motor drive circuits
• DC-AC inverters

Diode Arrays Procurement Notes

Verify the specific package variant required, as the datasheet lists packing quantities for related models like LQA40T300C (TO-220AB tube) and LQA40B300C (TO-263AB reel). Confirm RoHS compliance and lead-free plating status directly with the manufacturer or authorized distributor before finalizing procurement orders.

Diode Arrays Selection Notes

Select this component for applications requiring fast switching speeds and reduced EMI filter components. Ensure thermal management accounts for the specified junction-to-case thermal resistance. Verify that the operating voltage does not exceed the 200 V rating and that surge currents remain within the non-repetitive peak limits defined in the absolute maximum ratings.

Diode Arrays Part Context

Part of the Qspeed family designed to increase efficiency and eliminate snubber circuits. Utilizes Schottky technologies in design and construction. Halogen-free per IEC 61249-2-21. Package uses lead-free plating and green mold compound.

Diode Arrays Replacement Considerations

LQA40B200C shares identical electrical specifications but utilizes a TO-263AB surface-mount package instead of the through-hole TO-220AB form factor used by the LQA40T200C.
