SI7234DP-T1-GE3

Overview

The Vishay Siliconix SI7234DP-T1-GE3 is a dual N-channel MOSFET utilizing TrenchFET technology, housed in a PowerPAK SO-8 package. It features a 12 V drain-source voltage rating and supports a continuous drain current of up to 60 A at TC = 25 °C. The device exhibits a maximum on-state resistance of 0.0034 Ω at VGS = 4.5 V and 0.0050 Ω at VGS = 2.5 V. Total gate charge is typically 37 nC at VGS = 4.5 V. Thermal performance includes a junction-to-case resistance of 2.7 °C/W maximum and a junction-to-ambient resistance of 35 °C/W maximum.

Feature Summary

• Dual N-channel configuration with independent gate control for each channel
• TrenchFET power MOSFET architecture providing low on-state resistance
• Leadless PowerPAK SO-8 package design enabling direct thermal path to the substrate

Applications

• Synchronous rectification circuits
• DC/DC point-of-load converters

Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number and ordering suffix against official Vishay documentation. Confirm that the specific revision matches the required datasheet version. Ensure compliance with RoHS and halogen-free material standards as specified in the product summary. Validate package dimensions against the provided outline drawing prior to PCB layout integration.

Selection Notes

Select this component when a compact dual N-channel solution is required for low-voltage applications. The PowerPAK SO-8 footprint allows for direct substitution into standard SO-8 land patterns while offering superior thermal dissipation characteristics compared to traditional leaded packages. Evaluate thermal resistance requirements based on the intended case temperature and ambient conditions.

Part Context

This component belongs to the Vishay Siliconix TrenchFET family, designed for high-efficiency switching applications. The dual configuration integrates two independent N-channel MOSFETs within a single surface-mount package. The PowerPAK SO-8 construction provides a larger die area relative to standard SO-8 packages, facilitating higher current handling capabilities without increasing the board footprint.

Replacement Considerations

Direct pin-compatible replacements within the same package may include other Vishay dual N-channel MOSFETs rated for 12 V or lower. Verify that alternative devices meet the required on-resistance and current specifications. Ensure that the thermal resistance parameters of any substitute component are compatible with the existing cooling design.
