NTK3139PT1G

Single FETs, MOSFETs Overview

The NTK3139PT1G is a single P-channel enhancement mode MOSFET manufactured by onsemi. It features a 20 V drain-source breakdown voltage and supports continuous drain currents up to 780 mA or 870 mA depending on the specific datasheet reference. The device utilizes a SOT-723 surface-mount package with three pins. Key electrical characteristics include a maximum on-resistance of 380 mOhms, a gate-source voltage range of -6 V to 6 V, and a threshold voltage of 1.2 V. It operates within a temperature range of -55 °C to +150 °C with a power dissipation rating of 310 mW.

Single FETs, MOSFETs Procurement Notes

Verify the specific current rating (780 mA vs 870 mA) against the latest official datasheet, as sources vary. Confirm the SOT-723 package type matches your PCB footprint requirements. Ensure the T1 suffix indicates the correct reel quantity (4000 units) for your assembly line equipment calibration. Cross-reference the RoHS compliance status with current regulatory standards before finalizing procurement.

Single FETs, MOSFETs Selection Notes

Select this component when a small-form-factor P-channel MOSFET is required for low-voltage applications. The 20 V rating suits systems operating below this threshold. Consider the 380 mOhm on-resistance for efficiency needs. Verify that the SOT-723 package dimensions fit the design constraints. Compare performance against other NTK series parts if higher current or different voltage ratings are needed.

Single FETs, MOSFETs Part Context

This part belongs to the NTK3139P series from onsemi, focusing on low-voltage power switching solutions. It is distinct from N-channel variants and higher-voltage MOSFETs like the NTB52N10G. The T1 suffix denotes a specific tape-and-reel packaging option containing 4000 units per reel for SOT-723 packages, differing from T5 options which contain 8000 units.

Single FETs, MOSFETs Replacement Considerations

Check for direct substitutes within the NTK series such as NTK3134NT5H, ensuring pinout and electrical parameters align. Verify package compatibility between SOT-723 and potential alternatives. Confirm that any replacement maintains the P-channel polarity and similar voltage/current ratings.
