Diode Arrays Procurement Notes

Verify the specific package variant (TO-220AB) against project requirements. Confirm RoHS compliance status as indicated in datasheets. Ensure thermal management design accounts for the 3.0°C/W junction-to-case resistance. Validate marking codes match Littelfuse naming conventions. Check for any recent product change notices affecting specifications or availability.

Diode Arrays Selection Notes

Select this component for applications requiring low conduction losses and high-frequency operation. The common cathode setup simplifies circuit layout for dual-rail or bridge configurations. Consider the 80V reverse voltage rating relative to system transients. Evaluate thermal performance under continuous load conditions using the specified thermal resistance values.

Diode Arrays FAQ

What is the maximum non-repetitive surge current?

The peak one-cycle non-repetitive surge current is 100A per leg under an 8.3ms half-sine pulse condition.

How does temperature affect forward voltage?

Forward voltage decreases as temperature increases; it drops from a max of 0.81V at 25°C to 0.70V at 125°C when tested at 10A.

What is the reverse leakage current specification?

Reverse current is typically 24μA and maximally 600μA at rated voltage and 25°C junction temperature.
