Diode Arrays Procurement Notes

Verify the specific ordering suffix 'N' corresponds to the TO-252 DPAK surface-mount package configuration. Confirm RoHS compliance and halogen-free status per IEC 61249-2-21 standards during procurement. Ensure thermal management aligns with the specified junction-to-case thermal resistance values for optimal performance.

Diode Arrays Selection Notes

Select this component for applications requiring extremely fast switching and high efficiency. Its ultra-low QRR reduces EMI filter component size and count while eliminating the need for snubber circuits. Suitable for designs prioritizing high dI/dt capabilities and soft recovery behavior in compact surface-mount layouts.

Diode Arrays Part Context

Part of the Power Integrations Qspeed™ family of silicon diodes. Designed to offer the lowest QRR among 150 V silicon diodes. Utilizes Schottky technologies in its design and construction, requiring test setups similar to traditional Schottky configurations as noted in application note AN-300.

Diode Arrays Replacement Considerations

LQA20T150C shares identical electrical specifications but utilizes a TO-220AB through-hole package instead of the TO-252 DPAK form factor.
