What are the key features of SSM3K335R,LF(B?

  • 30 V drain-source breakdown voltage and 6 A drain current (ID) support a wide range of DC-DC converter and load switch designs
  • Ultra-low 38 mΩ (0.038 Ω) drain-source on-resistance minimizes conduction losses in battery-powered and portable applications
  • Built-in body diode enables synchronous rectification and freewheeling current paths without an external diode
  • Compact SOT-23F (R-PDSO-F3) 3-pin flat-lead package reduces PCB footprint in space-constrained designs

What is SSM3K335R,LF(B used for?

The SSM3K335R is used in portable consumer electronics, battery management circuits, and DC-DC converters where a compact 30 V / 6 A N-channel MOSFET with low on-resistance is needed to maximize power efficiency. Its ultra-low 38 mΩ RDS(on) makes it suitable for synchronous buck regulators and load switch circuits in smartphones, wearables, and IoT devices operating from single-cell Li-ion batteries. The SOT-23F package simplifies PCB layout in space-constrained designs such as USB power delivery modules and motor driver boards.

Frequently Asked Questions

What are the key voltage and current ratings of the SSM3K335R for DC-DC converter design?

The SSM3K335R is rated for a 30 V minimum drain-source breakdown voltage and a maximum drain current of 6 A, making it well suited for synchronous buck converters and load switches operating from 5 V to 24 V input rails in portable and industrial power applications.

How does the SSM3K335R's 38 mΩ on-resistance benefit battery-operated devices?

The 38 mΩ drain-source on-resistance (RDS(on) max) results in low conduction losses even at 6 A drain current, reducing heat dissipation and extending battery life in single-cell Li-ion powered devices such as smartphones, wearables, and IoT sensors that use N-channel MOSFET-based power switches.

Which PCB layouts benefit from the SSM3K335R's SOT-23F flat-lead package?

The SOT-23F (R-PDSO-F3) is a 3-pin flat-lead surface-mount package with a very small footprint, enabling tight component spacing on dense PCBs such as USB-C power delivery boards, portable chargers, and motor driver modules where the 30 V / 6 A MOSFET must fit within minimal board area.

Does the SSM3K335R include a built-in diode, and what role does it play in switching circuits?

Yes, the SSM3K335R includes a built-in body diode as part of its single-element N-channel MOSFET configuration. This diode provides a freewheeling current path in synchronous buck and boost converters, eliminating the need for an external Schottky diode and reducing component count in 30 V / 6 A switching power stages.
