Product details

What the 4 A and 8.5 mOhm ratings mean for your power rail

The SLG59M301V: That Rds(on) translates to roughly 136 mW of self-heating at full load — well within the thermal budget of the 8-FC-TDFN package if the copper pad is properly soldered to a thermal via array on the PCB.

Package and board-fit note for the layout engineer

The thermal pad should be connected to a ground plane with at least four via-in-pad to keep the junction temperature below the 85 °C ambient limit across the full 4 A load.

Frequently asked questions

Is the SLG59M301V a drop-in replacement for the SLG59M1496V?

Both are single-channel high-side load switches with CMOS input and the same 1:1 input-to-output ratio, but the SLG59M1496V is rated for 5.3 A with a slightly lower 7.8 mOhm Rds(on). The package and pinout differ — the SLG59M301V uses the 8-FC-TDFN (1.5x2) footprint, while the SLG59M1496V is in a different package variant. Confirm the PCB land pattern and current requirements before substituting.
