LQA20B300C

Diode Arrays Overview

The LQA20B300C is a Qspeed™ family common-cathode diode rated for 300 V peak repetitive reverse voltage and 10 A average forward current per diode. It features a TO-263AB surface-mount package with lead-free plating. Key electrical parameters include a typical reverse recovery charge of 38 nC at 125 °C, a maximum junction temperature of 150 °C, and a power dissipation of 52 W at 25 °C case temperature.

Diode Arrays Feature Summary

• Low reverse recovery charge and current to enable high dIF/dt switching up to 1000A/µs
• Soft recovery characteristic to reduce electromagnetic interference
• Eliminates the need for external snubber circuits in designs

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 ordering suffix 'B' corresponds to the TO-263AB package configuration as documented in the manufacturer's ordering information table. Confirm that the component meets RoHS compliance standards and utilizes lead-free plating and halogen-free green mold compound specifications required by the design.

Diode Arrays Selection Notes

Select this component when designing circuits requiring low reverse recovery charge to minimize switching losses and EMI filter size. The device supports extremely fast switching capabilities and operates effectively without snubber circuits. Ensure thermal management accommodates the specified junction-to-case resistance and power dissipation limits under expected operating conditions.

Diode Arrays Part Context

This component belongs to the Qspeed™ family of silicon diodes from Power Integrations. It is designed alongside the LQA20T300C variant, sharing identical electrical characteristics but differing in physical packaging. The series targets applications demanding high efficiency and reduced component count through optimized soft-recovery performance.

Diode Arrays Replacement Considerations

The LQA20T300C serves as a functional equivalent within the same family, offering identical electrical ratings but utilizing a TO-220AB through-hole package instead of the surface-mount form factor.
