STC5NF30V

Overview

The STC5NF30V is an N-channel Power MOSFET from the STripFET II family, designed for low-voltage applications. It features a maximum drain-source voltage of 30V and a continuous drain current of 5A. The device exhibits a typical on-resistance of 27mΩ at 4.5V gate drive and 35mΩ at 2.7V gate drive. Packaged in a TSSOP8 surface-mount outline, it supports efficient automated assembly while maintaining robust thermal performance for power management circuits.

Feature Summary

• STripFET II technology reduces conduction and switching losses
• Low threshold design enables direct drive from 2.7V logic sources
• Standard TSSOP8 package facilitates easy automated surface mount assembly

Applications

• Power management modules
• Load switches
• DC-DC converter outputs

Procurement Notes

Verify the component authenticity by checking the marking code against official STMicroelectronics documentation. Ensure the package type matches the required TSSOP8 specification. Confirm that the gate drive voltage requirements align with the system's logic levels to guarantee optimal on-resistance performance. Cross-reference the date code and lot number with supplier certificates to ensure traceability and compliance with quality standards.

Selection Notes

Select this component when a low-voltage, high-efficiency switch is required. The 2.7V drive capability makes it suitable for systems powered by single-cell lithium batteries or low-voltage rails. Consider the thermal dissipation capabilities of the TSSOP8 package relative to the expected current load. Ensure the application does not exceed the 30V drain-source voltage limit under any transient conditions.

Part Context

This part belongs to the STripFET II series, which utilizes advanced trench gate technology to minimize on-resistance. It is categorized within STMicroelectronics' discrete semiconductor portfolio, specifically targeting power management and motor control applications where efficiency and compact packaging are critical design constraints.

Replacement Considerations

Direct substitutes may include other 30V N-channel MOSFETs in TSSOP8 packages with comparable Rds(on) and Id ratings. Verify pinout compatibility and thermal characteristics before substitution. Check if alternative parts offer improved gate charge or lower capacitance for specific high-frequency applications.
