FDMS3622S is a 25V Asymmetric Dual N-Channel MOSFET produced by Fairchild Semiconductor Corporation. This product has low on-resistance, low inductance packaging, optimized layout and RoHS compliance.
The document describes the Fairchild Semiconductor FDMS3622S PowerTrench Power Stage, which integrates two specialized N-Channel MOSFETs (Q1 and Q2) into a single dual PQFN package. This design facilitates easy placement and routing of synchronous buck converters by optimizing the switch node connection.
The datasheet provides comprehensive electrical characteristics for both transistors, including maximum ratings such as a drain-to-source voltage of 25V and continuous drain currents up to 70A (Q1) or 34A (Q2). It also lists thermal resistance values, capacitance data, switching characteristics, and typical performance graphs regarding on-resistance versus temperature and gate charge.
