Product details

7.6 mOhm Rds(on) — conduction loss budget

The CSD87351Q5D: At 20 A and 8 V gate, the 7.6 mOhm maximum Rds(on) translates to roughly 3 W conduction loss per channel at full current — well within the 12 W package power limit, but the 5x6 LSON relies on the PCB copper pour for heat spreading. The 7.7 nC total gate charge at 4.5 V means the switching losses at 100 kHz with a 5 V gate driver stay under 100 mW per channel, making this part viable for high-frequency point-of-load converters.

Active production and compliance

It is ROHS3 compliant, with no exemptions that would trip up EU or California electronics import.

Frequently asked questions

Is the CSD87351Q5D an exact replacement for the CSD87350Q5D?

The CSD87351Q5D and CSD87350Q5D share the same 8-LSON (5x6) package and pinout, so they are footprint-compatible. The '351 has a lower Rds(on) (7.6 mOhm vs the '350's higher value) but a slightly higher gate charge. For a direct swap, confirm the gate drive can handle the 7.7 nC Qg at your switching frequency.
