The Vishay Dale SI4390DY-T1-E3 is an N-Channel Power MOSFET designed for high-side DC/DC conversion applications. It features a 30V drain-source voltage (Vds) and a continuous drain current (Id) of 8.5A at 25°C ambient temperature.
This MOSFET utilizes TrenchFET technology, offering low gate charge (Qg) for efficient switching. Key electrical parameters include a maximum Rds(on) of 9.5mOhm at Vgs = 10V and Id = 12.5A, and a gate threshold voltage (Vgs(th)) of 2.8V maximum at 250µA. The operating temperature range is -55°C to 150°C (TJ).
Packaged in an 8-SOIC surface mount configuration, the SI4390DY-T1-E3 is suitable for space-constrained designs. It is compliant with RoHS Directive 2002/95/EC and is halogen-free according to IEC 61249-2-21 definition. This part is also noted as obsolete, making substitute parts necessary for new designs or long-term availability.
