STMicroelectronics STS4DNF60L

Overview

STS4DNF60L from STMicroelectronics is an N-channel enhancement-mode Power MOSFET in SO-8 package, rated for 60 V V_DS, 4 A continuous drain current at T_C = 25 °C, and 0.045 Ω R_DS(on) at V_GS = 10 V. It features low gate threshold (1–2.5 V), robust 80 mJ single-pulse avalanche energy, and is optimized for DC-DC converters and load switching in industrial power supplies.

For engineers reviewing the STS4DNF60L datasheet, STS4DNF60L pinout, STS4DNF60L application, or STS4DNF60L equivalent, key selection criteria include its 0.045 Ω on-resistance at 10 V drive, SO-8 thermal resistance of 62.5 °C/W to PCB, 15 ns typical turn-on delay, and compatibility with 4.5 V logic-level gate drive in compact surface-mount designs.

Technical Context

This MOSFET employs ST's "single feature size" strip-based STripFET™ process, enabling high cell density and low R_DS(on) without compromising ruggedness. Its internal structure supports stable operation under unclamped inductive switching, with verified 80 mJ EAS and 16 A pulsed drain current capability.

The device exhibits temperature-stable gate threshold (1.0–2.5 V across –55 to 150 °C) and normalized R_DS(on) variation <1.5× from 25 °C to 125 °C. Dynamic parameters-including 1030 pF C_iss, 15 nC total gate charge, and 85 ns reverse recovery time-are characterized at V_DD = 48 V, ID = 4 A, and V_GS = 4.5 V per Figure 13.

Key Specifications

Pinout & Package

FAQ

Is STS4DNF60L suitable for 3.3 V microcontroller gate drive?

Yes. With a guaranteed gate threshold voltage range of 1.0–2.5 V and typical V_GS(th) = 1.7 V, STS4DNF60L fully enhances using standard 3.3 V GPIO outputs. At V_GS = 3.3 V, R_DS(on) remains ≤0.065 Ω (per Table 4), ensuring low-loss operation without external level shifters.

What is the maximum continuous power dissipation at ambient temperature?

At T_A = 25 °C with standard 1 in² FR-4 PCB (2 oz Cu), the junction-to-ambient thermal resistance is approximately 62.5 °C/W. Using T_j(max) = 150 °C, maximum continuous power is (150 − 25)/62.5 = 2 W - matching the datasheet's PTOT = 2 W rating at T_C = 25 °C.

Does STS4DNF60L have integrated ESD protection on the gate?

No. The device does not include on-chip gate ESD protection diodes. External 10 kΩ series gate resistor and optional 12 V Zener clamp between gate and source are recommended for handling human-body-model (HBM) ESD events during PCB assembly and system integration.

Can STS4DNF60L replace older STS4DNF30L in existing designs?

Yes, with verification. STS4DNF60L shares identical SO-8 footprint and pinout with STS4DNF30L but offers higher 60 V V_DS rating and slightly higher R_DS(on) (0.045 Ω vs. 0.035 Ω). System validation should confirm no overvoltage risk in 30 V circuits and acceptable thermal margin at peak load.
