FAE Expert Insights
"The SM6020P is an excellent high-side switch solution. The P-channel eliminates the need for complex gate drive circuits - just pull the gate low to turn on. The 60V rating handles 24V truck applications and load dumps. I've used it in battery disconnect switches and power distribution modules. The 20A capability is generous for most automotive loads. Just remember that P-channel has higher RDS(on) than equivalent N-channel, so account for that in thermal design."

Frequently Asked Questions
Why use P-channel instead of N-channel for high-side?
P-channel simplifies high-side switching because it turns on by pulling gate low (to ground), which is easy to do. N-channel on high-side requires gate voltage above source (which is at supply voltage), typically requiring a charge pump or bootstrap circuit. Trade-off is P-channel has higher RDS(on) and cost than equivalent N-channel.
Use P-channel for simple designs. Use N-channel with driver when best performance needed.
