LQA20T200C

Diode Arrays Overview

The LQA20T200C is a 200 V, 10 A per diode common-cathode rectifier from the Qspeed family. It features an ultra-low reverse recovery charge (QRR) of 48.4 nC at 125 °C and a softness factor (tb/ta) of 0.34. The device supports high dIF/dt switching up to 1000 A/µs with a maximum non-repetitive surge current of 350 A. Packaged in TO-220AB, it operates within a junction temperature range of -55 °C to 150 °C.

Diode Arrays Feature Summary

• Low reverse recovery charge (QRR), low peak reverse recovery current (IRRM), and low reverse recovery time (tRR).
• Capable of handling extremely fast switching rates with high dIF/dt values up to 1000 A/µs.
• Soft recovery waveform characteristics that minimize electromagnetic interference.

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 type during ordering, as the 'T' suffix indicates the TO-220AB through-hole variant. Confirm compliance with RoHS standards and halogen-free requirements per IEC 61249-2-21. Ensure thermal management aligns with the specified junction-to-case resistance for the selected mounting method.

Diode Arrays Selection Notes

Select this component for designs requiring minimal snubber circuitry due to its ultra-low QRR. Evaluate thermal performance against the 1.5 °C/W junction-to-case resistance per device. Consider the 200 V repetitive reverse voltage rating relative to system transients and ensure the operating junction temperature remains within the -55 °C to 150 °C range.

Diode Arrays Part Context

This part belongs to the Qspeed family of silicon diodes manufactured by Power Integrations. The family is characterized by having the lowest QRR among comparable 200 V silicon diodes. The LQA20T200C shares specifications with the LQA20N200C, differing only in the physical package configuration.
