STC5NF20V

Overview

The STC5NF20V is a dual N-channel Power MOSFET from the STripFET II series, housed in an 8-TSSOP package. It features a 20V drain-source voltage and a typical on-resistance of 30mΩ. The device supports a continuous drain current of 5A and utilizes a low threshold gate drive capability starting at 2.7V. Key electrical parameters include a fall time of 33ns and a minimum forward transconductance of 9.5S, designed for efficient surface mount assembly.

Feature Summary

• Ultra-low threshold gate drive enabling operation with 2.7V logic levels
• Dual N-channel configuration within a standard TSSOP-8 outline
• Optimized for automated surface mount assembly processes

Applications

• Low-voltage DC-DC converter circuits
• Power management modules requiring small form factors
• Battery-powered equipment load switching

Procurement Notes

Verify the specific ordering suffix to confirm the exact packaging type, such as tape-and-reel or Digi-Reel, as these variations affect handling procedures. Ensure the component matches the 8-TSSOP physical dimensions and pinout configuration required by the target PCB layout. Cross-reference the manufacturer's latest datasheet to confirm compliance with RoHS standards and environmental specifications before finalizing procurement orders.

Selection Notes

Select this component when space constraints necessitate a dual-channel solution in a compact TSSOP-8 footprint. It is suitable for applications requiring fast switching speeds indicated by the 33ns fall time. Consider the 2.7V drive requirement for compatibility with low-voltage control interfaces. Evaluate the thermal performance of the package against the expected 5A current load to ensure adequate heat dissipation without additional heatsinking.

Part Context

This part belongs to the STripFET II family, utilizing STMicroelectronics' single feature size strip-based process technology. This manufacturing approach allows for reduced on-resistance and improved power density compared to previous generations. The dual configuration integrates two independent N-channel devices into a single package, facilitating complex power switching topologies in minimal board area.

Replacement Considerations

The STS6NF20V serves as a functional substitute, offering similar 20V characteristics but with a higher 6A current rating and SO-8 packaging. Verify that the pinout compatibility between TSSOP-8 and SO-8 packages aligns with the existing design constraints before implementing any substitution.
