MOSFET Trims On-Resistance Down to 34 mO at 4.5 V

Measuring 1.6 mm x 1.6 mm x 0.8 mm, the SiB437EDKT 8V, p-channel TrenchFET power MOSFET touts the industry's lowest on-resistance: 34 mΩ at 4.5V. The SiB437EDKT is allegedly the only such device to offer an on-resistance rating down to 1.2 V. On-resistance is 34 mΩ at 4.5V, 63 mΩ at 1.8V, 84 mΩ at 1.5V, and 180 mΩ at 1.2V. The SiB437EDKT is halogen-free in accordance with the IEC 61249-2-21 definition and compliant to RoHS Directive 2002/95/EC. Pricing starts at $0.11 each/100,000.
