SI4814BDY-T1-E3

Overview

The Vishay Siliconix Si4814BDY-T1-E3 is a dual N-channel MOSFET with an integrated Schottky diode in an SO-8 package. It features a 30 V drain-source voltage rating and low on-state resistance of 0.018 Ω at VGS = 10 V. Continuous drain current reaches 10 A for Channel 1 and 10.5 A for Channel 2 at TC = 25 °C. The device includes a Schottky diode with a forward voltage of 0.50 V at 1.0 A. Operating junction temperature ranges from -55 °C to +150 °C, supporting high-power density applications.

Feature Summary

Integrates two independent N-channel MOSFETs with a common source connection and a dedicated Schottky diode within a single LITTLE FOOT Plus package.
Provides low on-state resistance and fast switching characteristics suitable for synchronous rectification and DC/DC converter topologies.
Features a built-in Schottky diode to minimize reverse recovery losses and improve overall circuit efficiency.

Applications

DC/DC converters
Notebook power management circuits

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm compliance requirements. The T1 suffix indicates tape and reel packaging, while E3 denotes lead-free composition. Confirm that the component meets all relevant environmental standards required for the intended manufacturing process before finalizing procurement orders.

Selection Notes

Select this component when a compact solution combining dual N-channel MOSFETs and a Schottky diode is required. Ensure the thermal design accommodates the specified power dissipation limits. Verify that the gate drive voltage aligns with the RDS(on) specifications for optimal performance in the target application environment.
