Product details
Frequently asked questions
What is the Rds(on) of BSC030N03MSGATMA1?
Maximum on-resistance is 3 mOhm at a gate drive of 10 V and a drain current of 30 A.
What is the gate charge of BSC030N03MSGATMA1?
Maximum gate charge is 73 nC at a 10 V gate drive.
Can BSC030N03MSGATMA1 be used for high-frequency switching?
The 73 nC gate charge and 5700 pF input capacitance suit switching frequencies in the 100–300 kHz range. For MHz-range converters, a part with lower Qg and Ciss would be a better fit.
