The SI3134K-TP is a single N-channel enhancement mode MOSFET manufactured by Micro Commercial Components. It utilizes silicon technology and is housed in an SOT-723-3 surface-mount package. The device features a drain-source breakdown voltage of 20 V and supports a continuous drain current of 750 mA. Its on-resistance is specified at 380 mOhms, with a gate-source voltage range of ±12 V and a threshold voltage of 350 mV. Power dissipation is rated at 150 mW, operating within a temperature range of -55°C to +150°C.
Verify the component status as Not Recommended for New Designs (NRND) before initiating procurement. Confirm that the specific SOT-723-3 package variant aligns with existing board layouts. Ensure compliance with RoHS requirements and validate that the manufacturer's datasheet specifications meet all operational constraints for the intended design environment.
Select this component for applications requiring a compact N-channel switch with moderate current handling capabilities. Evaluate the thermal performance against the 150 mW dissipation limit under expected operating conditions. Consider the 20 V breakdown voltage margin relative to the system supply rails to ensure reliable operation without exceeding absolute maximum ratings.
This part belongs to the SI3134 series from Micro Commercial Components, which includes various packaging options such as SOT-363 and DFN1006-3. The K suffix typically denotes the SOT-723 package configuration. The series provides standardized small-signal field-effect transistor solutions for general-purpose switching tasks in consumer electronics.
