SI3134KDWA-TP

Overview

The SI3134KDWA-TP is a dual N-channel MOSFET manufactured by Micro Commercial Components (MCC). It features a SOT-363S surface-mount package and operates with a drain-source voltage of 20 V. The device supports a continuous drain current of 750 mA at 25°C and dissipates up to 150 mW. Key electrical parameters include a maximum on-resistance of 800 milliohms at 450 mA and 1.8 V gate drive, and a threshold voltage of 1 V at 250 µA. Input capacitance is rated at 120 pF at 16 V. The component functions within a temperature range of -55°C to +150°C junction temperature.

Procurement Notes

Verify the specific suffix KDWA against the manufacturer's official datasheet to confirm pinout compatibility and electrical tolerances. Ensure the procurement source provides valid RoHS compliance documentation. Confirm that the supplier handles the SOT-363S packaging format correctly to prevent damage during handling. Validate that the batch meets the specified operating temperature range requirements for the intended application environment.

Selection Notes

Select this component when a dual N-channel configuration is required in a minimal footprint. Compare the 800 milliohm on-resistance against circuit loss requirements. Verify that the 20 V breakdown voltage exceeds the maximum system voltage. Consider the 150 mW power dissipation limit relative to thermal management capabilities. Ensure the SOT-363S package fits the available board space constraints.
