SI4214DY-T1-GE3

Overview

The Vishay Siliconix SI4214DY-T1-GE3 is a dual N-channel MOSFET utilizing TrenchFET technology, housed in an SO-8 surface-mount package. It features a drain-source voltage (VDS) of 30 V and a gate-source voltage (VGS) rating of ±20 V. At VGS = 10 V, the on-state resistance (RDS(on)) is typically 0.0235 Ω with a continuous drain current (ID) of 8.5 A at TC = 25 °C. The total gate charge (Qg) is typically 6.7 nC at VGS = 10 V. The device supports an operating junction temperature range from -55 °C to +150 °C.

Feature Summary

• Dual N-channel configuration within a single SO-8 package
• TrenchFET power MOSFET architecture for optimized performance
• Validated against 100% Rg and UIS testing requirements

Applications

• PC system power distribution
• Low current DC/DC converter circuits

Procurement Notes

Verify component authenticity by cross-referencing the manufacturer's datasheet document number 64726 and revision S09-1223-Rev. B. Confirm that the ordering suffix indicates lead-free and halogen-free compliance per IEC 61249-2-21 standards. Ensure the physical package matches the narrow SOIC-8 dimensions specified in Vishay documentation 71192.

Selection Notes

Select this component when a compact dual N-channel solution is required for low-voltage switching applications. The SO-8 package provides efficient thermal dissipation through the drain foot. Verify that the 30 V breakdown voltage aligns with the specific circuit rail requirements and that the 8.5 A continuous current capacity meets the load demands under the intended thermal conditions.

Part Context

This part belongs to the Vishay Siliconix Si4214 series of dual N-channel MOSFETs. It utilizes the standard SO-8 footprint, which is widely supported by automated pick-and-place equipment. The T1 suffix denotes reel packaging, while GE3 confirms environmental compliance. This component serves as a direct replacement for legacy dual MOSFET designs requiring similar electrical characteristics.

Replacement Considerations

Consult official Vishay resources for confirmed substitute part numbers. Do not assume functional equivalence based solely on pinout compatibility or generic specifications.
