Product details

Overview

STP95N04 from STMicroelectronics is an N-channel enhancement-mode Power MOSFET in TO-220 package, rated for 40V V_DS, 5.4 mΩ R_DS(on) at V_GS = 10V, 80A continuous drain current at T_C = 25°C, and 110W total power dissipation. It features rugged avalanche capability (400 mJ single-pulse), low gate charge (40 nC), and standard threshold drive for compatibility with 5V logic.

For engineers reviewing the STP95N04 datasheet, STP95N04 pinout, STP95N04 application, or STP95N04 equivalent, this device is selected for high-current DC switching in industrial motor drives, DC-DC converter primary-side switches, and battery protection circuits where low conduction loss and robust unclamped inductive switching performance are critical.

Technical Context

This MOSFET employs ST's STripFET™ II process with "Single Feature Size™" strip geometry, enabling high cell density and reproducible manufacturing. Its structure delivers low R_DS(on) while maintaining strong avalanche ruggedness and fast switching via minimized gate-drain charge (Q_gd = 8 nC) and low output capacitance (C_oss = 580 pF).

The device supports standard gate drive (V_GS(th) = 2–4 V), operates up to 175°C junction temperature, and is qualified per JEDEC JESD22-A108 for reliability. Its source-drain diode exhibits 1.5 V forward voltage at 80 A and 45 ns reverse recovery time under specified inductive load conditions.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	40 V - Maximum blocking voltage before avalanche onset; defines safe operation in 24V/36V bus systems.
R_DS(on)	5.4 mΩ @ V_GS = 10 V - Enables ≤4.3 W conduction loss at 80 A, reducing heatsink requirements.
I_D (cont)	80 A @ T_C = 25°C - Sustains high-current loads in motor H-bridge legs or power supply outputs.
E_AS	400 mJ - Withstands unclamped inductive energy spikes without failure, critical for relay/motor snubbing.
Q_g	40 nC - Determines gate driver current demand; enables efficient 100 kHz+ switching with moderate drive strength.
T_j(max)	175°C - Supports operation in sealed enclosures or high-ambient industrial environments.
R_th(j–case)	1.36 °C/W - Allows direct thermal coupling to heatsinks; 80 A @ 100°C case yields ~105°C junction rise.

Pinout & Package

TO-220 package: 3-terminal through-hole mounting with isolated tab (drain-connected). Standard lead-forming allows vertical or horizontal PCB mounting with mechanical stress relief.

Pin/Terminal	Circuit Role	Design Meaning
1 (Source)	Power return path for channel current	Low-inductance connection point for ground plane routing; ties directly to PCB ground pour.
2 (Gate)	Control electrode for channel modulation	High-impedance input requiring <200 nA leakage; sensitive to ESD-requires series resistor and TVS clamp.
3 (Drain)	Main high-side power terminal	Internally connected to metal tab; must be electrically isolated from heatsink unless system ground referenced.

Key Features

Feature	Design Value
100% avalanche tested	Guarantees minimum 400 mJ single-pulse energy handling-no screening lot sampling.
Standard threshold drive (V_GS(th) = 2–4 V)	Direct interface with 3.3V/5V microcontrollers and gate drivers without level-shifting.
Low gate charge (Q_g = 40 nC)	Reduces switching losses and driver power consumption in high-frequency SMPS designs.
Rugged source-drain diode (t_rr = 45 ns)	Minimizes voltage overshoot during freewheeling in synchronous rectification and half-bridge topologies.

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	R_DS(on) = 4 mΩ (lower), but V_DS = 40V same; Q_g = 131 nC (3.3× higher); TO-220 package	Higher gate drive power required; slower switching; better for low-frequency, ultra-low-loss apps	Select when minimizing conduction loss dominates over switching loss and gate drive capability is ample.
IXTP95N04T	R_DS(on) = 5.5 mΩ (nearly identical); V_DS = 40V; Q_g = 36 nC (slightly lower); TO-220 package	Near drop-in replacement with marginally faster turn-on; same thermal profile	Prefer when seeking second-source availability with matched R_DS(on) and improved gate efficiency.

Compared with IRF1404PBF and IXTP95N04T, STP95N04 offers balanced trade-offs: lower Q_g than IRF1404PBF for efficient high-frequency use, and tighter R_DS(on) tolerance than IXTP95N04T while maintaining ST's proven avalanche ruggedness for industrial fault tolerance.

FAQ

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

The STP95N04 supports 65A continuous drain current at T_C = 100°C, as specified in Table 1 of the datasheet. This derating reflects thermal limitations of the TO-220 package and ensures safe operation within its 1.36 °C/W junction-to-case thermal resistance.

Is the STP95N04 RoHS-compliant and lead-free?

Yes. The STP95N04 is manufactured in ECOPACK® packaging with lead-free second-level interconnect, compliant with JEDEC JESD97 and RoHS Directive 2011/65/EU. The inner box label indicates the lead-free category per ST's environmental compliance program.

Can STP95N04 replace STD95N04 in existing designs?

Yes-STP95N04 and STD95N04 share identical electrical specifications (V_DS, R_DS(on), I_D, P_TOT) and thermal ratings. The only difference is package: STP95N04 uses TO-220, STD95N04 uses DPAK. Mechanical redesign is required, but no electrical requalification is needed.

What is the recommended gate resistor value for 100 kHz switching?

A 4.7 Ω gate resistor is validated in the datasheet (Table 5 test conditions) for 100 kHz-class operation. This value balances switching speed (t_d(off) = 40 ns, t_f = 15 ns) and gate oscillation suppression, assuming a 12V gate drive with ≤2A peak current capability.
