Product details
Overview
STP80NF03L-04 from STMicroelectronics is an N-channel enhancement-mode Power MOSFET in TO-220 package, rated for 30 V VDS, 80 A continuous drain current, and 4.0 mΩ typical RDS(on) at VGS = 10 V. It features 100% avalanche tested ruggedness, 2.0 V/ns dv/dt capability, and is used in high-current automotive lamp drivers and DC-DC converters.
For engineers reviewing the STP80NF03L-04 datasheet, STP80NF03L-04 pinout, STP80NF03L-04 application, or STP80NF03L-04 equivalent, key selection criteria include verified RDS(on) at 4.5 V gate drive, unclamped inductive switching performance, thermal resistance (0.5 °C/W junction-to-case), and TO-220 lead-form compatibility with legacy PCB footprints.
Technical Context
This MOSFET employs ST's StripFET™ II process with single-feature-size geometry, enabling high cell density and low on-resistance without compromising avalanche robustness. Its gate threshold voltage (1.0–2.5 V) supports direct logic-level drive from 3.3 V or 5 V microcontrollers.
The device exhibits fully characterized dynamic parameters: 85 nC total gate charge, 290 pF reverse transfer capacitance, and 75 ns diode reverse recovery time under 100 A/µs di/dt - critical for hard-switched motor control and synchronous rectification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 30 V - maximum blocking voltage compatible with 24 V automotive systems and 12 V industrial rails |
| RDS(on) @ VGS=10 V | 4.0 mΩ typical - enables <1 W conduction loss at 50 A, reducing heatsink requirements |
| ID (continuous) | 80 A @ TC = 25°C - sustained high-current capability with TO-220 copper tab thermal path |
| EAS | 2.3 J - single-pulse avalanche energy rating confirms reliability in inductive load turn-off |
| Qg | 85 nC - quantifies gate drive power needed for 100 kHz switching in DC-DC applications |
| dv/dt immunity | 2.0 V/ns - validated capability to withstand fast transient coupling without spurious turn-on |
| Rth(j-c) | 0.5 °C/W - allows direct mounting to heatsink for >200 W power dissipation in forced-air environments |
Pinout & Package
TO-220 package with vertical metal tab (drain-connected), standard 3-pin through-hole configuration. Mounting hole centered on tab for mechanical stability and thermal interface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Source) | Source terminal | Low-side return path; electrically tied to PCB ground plane for minimal loop inductance |
| Pin 2 (Gate) | Control input | High-impedance MOS gate requiring <100 nA leakage; sensitive to ESD and layout-induced ringing |
| Pin 3 (Drain) | Power output / heat sink interface | Internally connected to metal tab; must be electrically isolated from heatsink unless system ground reference permits |
Key Features
| Feature | Design Value |
|---|---|
| 100% avalanche tested | Guarantees operation under unclamped inductive switching stress up to 40 A repetitive avalanche current |
| Logic-level gate drive | Threshold voltage range (1.0–2.5 V) ensures full enhancement with 3.3 V or 5 V MCU GPIO outputs |
| StripFET™ II process | Enables 4.0 mΩ RDS(on) in TO-220 without die size penalty, improving power density vs prior generation |
| Low Qgd/Qg ratio | 40/85 nC = 0.47 - reduces Miller effect, supporting stable 100+ kHz switching with moderate gate resistors |
Applications
| Automotive Lamp Driver | DC-DC Synchronous Rectifier |
|---|---|
Use Scenario: High-side or low-side switching of halogen and LED headlamps in 12 V vehicle electrical systems. IC Role / Device Role / Timing Role: Power switch controlling lamp current; operates in linear or PWM mode with <10 µs turn-on delay.

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 | RDS(on) = 4.0 mΩ @ 10 V, but higher Qg (131 nC) and no avalanche rating | Lacks 100% avalanche testing; unsuitable for unclamped inductive loads like solenoids or relays | Prefer STP80NF03L-04 where inductive energy absorption is required |
| STP75NF03L | Same family, lower ID (75 A) and slightly higher RDS(on) (4.5 mΩ typ) | Identical pinout and thermal profile; suitable for cost-sensitive designs with marginally lower current demand | Select when 80 A rating is unnecessary and BOM consolidation is prioritized |
Compared with IRF1404PBF and STP75NF03L, STP80NF03L-04 delivers superior avalanche ruggedness and lower gate charge per ampere, making it optimal for automotive and industrial switching where reliability under transient stress is non-negotiable.

FAQ
Is STP80NF03L-04 suitable for 3.3 V microcontroller gate drive?
Yes. With a gate threshold voltage range of 1.0–2.5 V and guaranteed RDS(on) ≤ 4.5 mΩ at VGS = 4.5 V, it achieves full enhancement using 3.3 V logic-level outputs - confirmed by datasheet test conditions and application notes for automotive body control modules.
What is the maximum safe operating temperature for continuous 80 A operation?
Continuous 80 A operation is rated only at case temperature ≤ 25°C. At TC = 100°C, the device still supports 80 A, but practical use requires thermal design ensuring junction temperature stays ≤ 175°C - typically achieved with 0.5 °C/W heatsinking and ambient ≤ 70°C.
Does STP80NF03L-04 have integrated ESD protection on the gate?
No. The gate is unprotected against electrostatic discharge per datasheet absolute maximum ratings (±20 V VGS). External gate protection - such as a 10 kΩ series resistor and 12 V Zener clamp to source - is required during PCB handling and assembly per STMicroelectronics AN411.
Can STP80NF03L-04 replace STP75NF03L in existing designs?
Yes, with identical TO-220 footprint, pinout, and thermal characteristics. The STP80NF03L-04 offers 5 A higher current rating and marginally lower RDS(on), providing headroom for derating or increased efficiency - no layout or drive circuit changes are needed.
