LQA10T200C

Diode Arrays Overview

The LQA10T200C is a Qspeed™ family common-cathode rectifier diode manufactured by Power Integrations. It features a peak repetitive reverse voltage (VRRM) of 200 V and an average forward current (IF(AVG)) of 5 A per diode. The device exhibits a typical reverse recovery charge (QRR) of 32.4 nC at 125 °C and a maximum non-repetitive peak surge current of 60 A. Packaged in TO-220AB, it operates within a junction temperature range of –55 to 150 °C.

Diode Arrays Feature Summary

• Low reverse recovery charge (QRR), low reverse recovery current (IRRM), and low reverse recovery time (tRR)
• Capable of high dIF/dt switching rates up to 1000A/µs
• Soft recovery waveform characteristics

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 procurement, as the 'LQA10T200C' designation corresponds to the TO-220AB through-hole package. Confirm that the ordering suffix matches the required physical form factor for your assembly process. Ensure compliance with RoHS standards and lead-free plating requirements specified in the datasheet before finalizing component selection.

Diode Arrays Selection Notes

Select this component when designing circuits requiring ultra-low reverse recovery charge to minimize switching losses and electromagnetic interference. It is suitable for applications demanding high efficiency and fast switching speeds without the need for external snubber circuits. Consider the thermal resistance and power dissipation limits relative to the expected case temperature and ambient conditions.

Diode Arrays Part Context

This device belongs to the Qspeed™ family from Power Integrations, designed to offer the lowest QRR among 200 V silicon diodes. The family utilizes Schottky technologies to achieve superior dynamic performance compared to traditional silicon rectifiers. This specific model provides a common-cathode configuration ideal for synchronous rectification or bridge applications.

Diode Arrays Replacement Considerations

The LQA10N200C serves as a functional equivalent within the same series but utilizes a TO-252 DPAK surface-mount package instead of the TO-220AB through-hole format. Verify pinout compatibility and thermal management requirements when substituting between these package types.
