Product details

Overview

STP100NF04 from STMicroelectronics is an automotive-grade N-channel Power MOSFET with 40 V V_DS, 4.3 mΩ typ. R_DS(on), 120 A continuous drain current, and TO-220 package. It serves as a primary high-current switching device in isolated DC-DC converters for telecom and computing power supplies where low gate charge and robust avalanche capability are critical.

For engineers reviewing the STP100NF04 datasheet, STP100NF04 pinout, STP100NF04 application, or STP100NF04 equivalent, key selection factors include its AEC-Q101 qualification, 1.2 J single-pulse avalanche energy, 110–150 nC total gate charge, and thermal resistance of 0.5 °C/W junction-to-case - all essential for high-reliability industrial and automotive power designs.

Technical Context

This STripFET™ II MOSFET employs a planar vertical structure optimized to minimize input capacitance (C_iss = 5100 pF) and gate charge (Q_g = 110–150 nC), enabling fast switching with reduced driver losses. Its 6 V/ns dv/dt rating and 100% avalanche testing support operation under harsh transient conditions in unclamped inductive loads.

The device integrates a robust body diode with 120 A continuous source-drain current and 75 ns reverse recovery time at T_j = 150 °C, making it suitable for synchronous rectification and freewheeling roles in high-frequency SMPS topologies without external diode supplementation.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	40 V - Maximum blocking voltage compatible with 36 V nominal automotive and 48 V telecom bus systems
R_DS(on) max	4.6 mΩ - Ensures ≤0.55 W conduction loss at 120 A, reducing heatsink requirements
I_D cont	120 A at T_C = 25 °C - Sustains full rated current with adequate PCB copper area and case cooling
E_AS	1.2 J - Enables reliable unclamped inductive switching without snubbers in motor drive or solenoid control
Q_g	110–150 nC - Low gate drive power demand supports efficient operation with standard PWM controllers
R_thj-case	0.5 °C/W - Allows 300 W dissipation with ≤150 °C junction rise above 25 °C case temperature
dv/dt	6 V/ns - Resists false turn-on during fast voltage transients in high-noise power stages

Pinout & Package

STP100NF04 is housed in a TO-220 package with exposed drain tab (pin 2) for thermal and electrical connection. The three-terminal configuration supports high-current, high-voltage switching with direct heatsink mounting.

Pin/Terminal	Circuit Role	Design Meaning
1 (G)	Gate	Control terminal requiring ≤±20 V drive; low Q_g enables fast turn-on/turn-off with minimal Miller effect
2 (TAB/D)	Drain (exposed tab)	Main high-side power path; electrically and thermally connected to heatsink; must be insulated if floating
3 (S)	Source	Power return and reference node for gate drive; ties to ground or low-side switch source in half-bridge

Key Features

Feature	Design Value
AEC-Q101 qualified	Validated for automotive powertrain and chassis applications per stress test requirements
100% avalanche tested	Each unit verified for single-pulse energy handling up to 1.2 J, ensuring field reliability
Exceptional dv/dt capability	6 V/ns immunity prevents spurious turn-on during rapid voltage transitions in noisy environments
Low gate charge (Q_g)	110–150 nC reduces driver IC power consumption and enables higher switching frequencies

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
IRF1404PBF	V_DS = 40 V, R_DS(on) = 4.0 mΩ, Q_g = 131 nC, non-AEC-Q101	Lacks automotive qualification; lower R_DS(on) but higher gate charge increases driver loss	Preferred for cost-sensitive industrial SMPS where AEC-Q101 is not required
IXTH120N04S3	V_DS = 40 V, R_DS(on) = 3.2 mΩ, Q_g = 170 nC, AEC-Q101 qualified	Lower on-resistance but higher Q_g demands stronger gate driver and increases switching loss	Selected when <3.5 mΩ R_DS(on) is mandatory and gate drive capability supports 170 nC

Compared with IRF1404PBF and IXTH120N04S3, STP100NF04 delivers balanced performance: AEC-Q101 compliance plus moderate Q_g and proven avalanche ruggedness - ideal for automotive and telecom designs needing reliability without over-spec'ed gate drive overhead.

FAQ

What is the maximum allowable junction temperature for STP100NF04?

The absolute maximum operating junction temperature is 175 °C, validated across the full automotive temperature range (−55 °C to +175 °C). Derating begins above 25 °C case temperature per the R_thj-case = 0.5 °C/W thermal resistance, allowing full 120 A current only with active heatsinking or forced-air cooling.

Does STP100NF04 require a gate resistor for stability?

Yes - a series gate resistor (typically 4.7 Ω to 10 Ω) is recommended to dampen ringing caused by parasitic inductance and prevent oscillation during switching. This value balances turn-on speed (35 ns t_d(on)) and EMI control, especially when driving inductive loads with high di/dt.

Can STP100NF04 replace STB100NF04T4 in a D²PAK footprint?

No - STP100NF04 uses TO-220 while STB100NF04T4 uses D²PAK (TO-263); they are not footprint-compatible. Though electrically identical, mechanical mounting, thermal interface, and PCB layout differ significantly. Direct replacement requires board redesign and requalification.

Is the body diode suitable for synchronous rectification?

Yes - the integrated body diode supports continuous 120 A source-drain current with 1.3 V forward voltage at 120 A and 75 ns reverse recovery time at 150 °C. However, for optimal efficiency above 100 kHz, an external Schottky diode or synchronous MOSFET is preferred due to Q_rr-related switching loss.
