Product details

Overview

STB200NF04L from STMicroelectronics is an N-channel enhancement-mode MOSFET in D²PAK package, rated for 40 V V_DSS, 3.0 mΩ typical R_DS(on) at V_GS = 10 V and I_D = 50 A, 120 A continuous drain current, and 1.4 J single-pulse avalanche energy - designed for high-current automotive power switching applications including motor control and DC-DC converters.

For engineers reviewing the STB200NF04L datasheet, STB200NF04L pinout, STB200NF04L application, or STB200NF04L equivalent, key selection criteria include low on-resistance at 5 V gate drive, rugged unclamped inductive switching capability, thermal resistance of 0.50 °C/W junction-to-case, and D²PAK tape-and-reel packaging for automated assembly.

Technical Context

This STripFET™ II MOSFET uses STMicroelectronics' Single Feature Size™ strip-based process to achieve high cell density and low R_DS(on) while maintaining robust avalanche performance (100% tested) and manufacturing reproducibility. Its gate threshold voltage ranges from 1 V to 4 V, enabling compatibility with both 5 V and 12 V logic-level drive systems.

The device features fast switching dynamics: 37 ns turn-on delay, 270 ns rise time, 90 ns turn-off delay, and 80 ns fall time under standard test conditions (V_DD = 20 V, I_D = 50 A, R_G = 4.7 Ω). Its 6400 pF input capacitance and 72 nC total gate charge support efficient high-frequency operation up to several hundred kHz in hard-switched topologies.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	40 V - Maximum blocking voltage in off-state; suitable for 24 V automotive bus and 36 V industrial DC systems.
R_DS(on) (typ)	3.0 mΩ at V_GS = 10 V, I_D = 50 A - Enables <1.5 W conduction loss at 120 A, critical for thermally constrained motor drives.
I_D (cont)	120 A at T_C = 25°C - Sustains high peak load currents without derating when mounted on adequate heatsink.
E_AS	1.4 J - Withstands unclamped inductive energy spikes in relay/motor switching without failure.
Q_g	72 nC - Determines gate driver power requirement; compatible with common 1–2 A peak gate drivers.
R_thj-case	0.50 °C/W - Enables direct thermal interface to heatsink; supports >250 W power dissipation with 125°C ΔT.

Pinout & Package

STB200NF04L is housed in a surface-mount D²PAK (TO-263) package with three terminals: Gate (G), Drain (D), and Source (S). The exposed drain pad provides low-inductance, high-current path and serves as primary thermal conduction surface to PCB copper.

Pin/Terminal	Circuit Role	Design Meaning
1 (Gate)	Control electrode	Receives gate drive signal; requires ≤±16 V rating and low-impedance drive to minimize switching losses.
2 (Drain)	High-side current path	Connected to load supply rail; electrically and thermally tied to large copper pour via exposed pad.
3 (Source)	Reference node / return path	Serves as power ground reference; must be routed with low inductance to reduce voltage overshoot during switching.

Key Features

Feature	Design Value
100% avalanche tested	Guarantees robustness against inductive kickback in automotive motor and solenoid switching without external snubbers.
Low R_DS(on) at 5 V drive	3.5 mΩ max at V_GS = 5 V enables direct microcontroller GPIO drive in space-constrained modules.
dv/dt immunity	3.6 V/ns rated - suppresses false turn-on in noisy high-di/dt environments like BLDC inverters.
Thermal stability	Normalized R_DS(on) variation <1.5× from 25°C to 175°C - ensures predictable conduction loss across full operating range.

Applications

Equivalent & Alternatives

The following parts are listed as comparable options for similar N-channel power MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IRF1404ZPBF	R_DS(on) = 4.0 mΩ (typ), 160 A I_D, TO-220 package, no avalanche rating	Lacks 100% avalanche testing; higher R_DS(on) increases conduction loss in high-current automotive use	Prefer only in cost-sensitive non-automotive industrial applications where avalanche stress is absent
IXTH120N04S3	R_DS(on) = 2.2 mΩ (typ), 120 A I_D, TO-247 package, 2.5 J E_AS	Higher avalanche energy but larger footprint and higher gate charge (105 nC)	Choose when higher ruggedness is required and board space allows TO-247; avoid if D²PAK footprint is fixed

Compared with IRF1404ZPBF and IXTH120N04S3, STB200NF04L uniquely balances ultra-low R_DS(on), industry-leading avalanche reliability, and compact D²PAK packaging - making it optimal for space-constrained, safety-critical automotive power stages where thermal and transient margins are non-negotiable.

FAQ

What is the maximum gate-source voltage rating for STB200NF04L?

The absolute maximum V_GS is ±16 V. Exceeding this risks permanent gate oxide damage. For reliable operation, gate drive should be limited to +10 V to +15 V for full enhancement and –5 V to –10 V for fast turn-off, especially in high-noise automotive environments where dv/dt-induced coupling may occur.

Does STB200NF04L support logic-level gate drive?

Yes - its gate threshold voltage (V_GS(th)) ranges from 1.0 V to 4.0 V, and it achieves 3.5 mΩ R_DS(on) at V_GS = 5 V. This enables direct drive from 5 V microcontrollers or gate drivers without level-shifting, though layout must minimize gate loop inductance to prevent oscillation.

How is thermal performance validated for STB200NF04L in D²PAK package?

Thermal resistance is measured per JEDEC JESD51-14 standards: R_thj-case = 0.50 °C/W is verified using a cold plate fixture with controlled case temperature; R_thj-pcb = 35 °C/W assumes 1 inch² FR4 board with 2 oz copper, and R_thja = 62.5 °C/W reflects natural convection on standard test board - all values confirmed in ST's official characterization report Rev. 1.

Is STB200NF04L qualified to AEC-Q101 standards?

While not explicitly marked "AEC-Q101 qualified" in the 2005 datasheet, STB200NF04L belongs to ST's automotive-grade STripFET™ II family and was designed, manufactured, and tested to meet AEC-Q101 stress requirements - evidenced by 100% avalanche testing, extended temperature range (–55°C to 175°C), and automotive application focus stated in the original release documentation.
