Product details

What this 12V NexFET does on the board

With a maximum Rds(on) of 9.3 mOhm at 4.5 V gate drive and 5 A drain current, this part is built for low-voltage, high-efficiency switching — think point-of-load converters, load switches, and battery protection in portable or embedded systems.

On-resistance and gate charge — the efficiency pair

The 9.3 mOhm Rds(on) at 4.5 V gate drive means conduction losses stay low even at several amps of load current. That 4.5 V drive level is important: it lets a 5 V rail or a 3.3 V system with a gate-drive booster turn the FET fully on without needing a 10 V supply. Gate charge is 6.6 nC at 4.5 V. For higher-frequency DC-DC converters, the low Qg keeps driver losses in check.

It is at home in outdoor telecom gear, engine-bay electronics, industrial motor drives, and battery packs that see thermal cycling. Maximum power dissipation is 2.7 W at 25°C ambient.

Frequently asked questions

Is CSD13202Q2 obsolete or not recommended for new designs?

No.

Is CSD13202Q2 suitable for load switch applications?

Yes. The 12 V Vds rating covers common system rails (3.3 V, 5 V, 12 V), the 22 A continuous drain rating provides ample headroom for most load-switch currents, and the 9.3 mOhm Rds(on) at 4.5 V gate drive keeps voltage drop and power dissipation low. The 6-WSON package with exposed pad handles the thermal load when the PCB layout provides adequate copper area.
