STMicroelectronics STP200NF04

Overview

STP200NF04 from STMicroelectronics is an N-channel 40 V, 120 A TO-220 power MOSFET with 3.7 mΩ R_DS(on) at V_GS = 10 V, 100% avalanche tested, and optimized for high-current switching in automotive and industrial DC-DC converters.

For engineers reviewing the STP200NF04 datasheet, STP200NF04 pinout, STP200NF04 application, or STP200NF04 equivalent, key selection criteria include its 310 W power dissipation, 1.5 V/ns dv/dt rating, 1.3 J single-pulse avalanche energy, and thermal resistance of 0.48 °C/W (junction-to-case), critical for high-reliability motor drive and battery protection designs.

Technical Context

This MOSFET employs ST's StripFET™ II process with single-feature-size strip geometry, enabling ultra-low on-resistance and high current density while maintaining rugged unclamped inductive switching capability. Its gate threshold voltage (2–4 V) supports standard 10 V logic-level drive without requiring level-shifting circuitry.

The device integrates a fast-recovery body diode with t_rr = 85 ns and Q_rr = 190 nC at T_j = 150 °C, making it suitable for synchronous rectification and freewheeling paths where reverse recovery losses must be minimized in high-frequency SMPS topologies.

Key Specifications

Pinout & Package

STP200NF04 uses the TO-220 package (3-pin, through-hole), with Pin 1 = Gate, Pin 2 = Drain (tab), Pin 3 = Source. The metal tab is electrically connected to the Drain terminal and must be isolated from chassis ground unless circuit topology requires common-drain configuration.

FAQ

What is the maximum continuous drain current for STP200NF04 at 100°C case temperature?

The STP200NF04 maintains 120 A continuous drain current rating up to T_C = 100 °C, per its Absolute Maximum Ratings table. This is enabled by its low R_DS(on) and 0.48 °C/W junction-to-case thermal resistance, allowing stable operation without derating in well-heatsinked applications.

Does STP200NF04 require a gate resistor for safe switching?

Yes-a gate resistor is required to control dV/dt and prevent oscillation. With 170 nC total gate charge and typical gate driver rise/fall times, a 4.7 Ω resistor (as used in the datasheet test circuit) limits peak gate current to ~2.1 A and ensures stable 320 ns rise time, avoiding shoot-through in half-bridge configurations.

Can STP200NF04 be used in synchronous rectification applications?

Yes-the integrated body diode has t_rr = 85 ns and Q_rr = 190 nC at 150 °C, enabling use in secondary-side synchronous rectification of forward or LLC converters up to 300 kHz. However, external Schottky diodes may still be preferred for <100 ns recovery or <100 °C operation due to lower Q_rr.

Is the TO-220 package of STP200NF04 lead (Pb)-free and RoHS compliant?

Yes-STP200NF04 is manufactured in accordance with STMicroelectronics' ECOPACK®2 standard, meeting RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. The TO-220 package uses matte tin plating on leads and Pb-free solder-compatible terminations.
