SiR186LDP N-Channel 60V (D-S) MOSFETs Vishay / Siliconix SiR186LDP N-Channel 60V (D-S) MOSFETs utilize TrenchFET® Gen IV power MOSFET technology. The SiR186LDP MOSFETs feature very low RDS Qg figure-of-merit (FOM) and are tuned for the lowest RDS Qoss FOM. The Vishay / Siliconix SiR186LDP N-Channel 60V (D-S) MOSFETs are ideal for synchronous rectification, primary-side switch, DC/DC converter, and motor drive switch applications.
