Product details

Overview

STP80NF10FP from STMicroelectronics is an N-channel enhancement-mode Power MOSFET in TO-220FP package, rated for 100 V V_DS, 38 A continuous drain current at T_C = 25°C, and 0.012 Ω typical R_DS(on) at V_GS = 10 V. It features low gate charge (Q_g = 140 nC), 100% avalanche tested ruggedness, and exceptional dv/dt capability-designed as primary switch in high-efficiency isolated DC-DC converters for telecom and server power supplies.

For engineers reviewing the STP80NF10FP datasheet, STP80NF10FP pinout, STP80NF10FP application, or STP80NF10FP equivalent, key selection criteria include its 0.012 Ω on-resistance at 10 V gate drive, 152 A pulsed drain current capability, 350 mJ single-pulse avalanche energy rating, and TO-220FP package with insulated tab for simplified heatsinking in high-power switching designs.

Technical Context

This device employs ST's STripFET™ II process to minimize input capacitance (C_iss = 4300 pF) and gate charge, enabling fast switching with low drive loss. Its 9 V/ns peak diode recovery dv/dt rating and 155 ns reverse recovery time (trr) support robust operation in hard-switched inductive loads.

The MOSFET integrates a source-drain diode with 1.3 V forward voltage at 80 A and 11 A peak reverse recovery current (I_RRM) under specified conditions. Thermal resistance junction-to-case is 3.33 °C/W, supporting high-power density layouts when mounted to heatsinks via the insulated tab.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	100 V - maximum blocking voltage in off-state; suitable for 48 V input bus systems with margin.
R_DS(on)	0.012 Ω (typ) at V_GS = 10 V - enables <1.9 W conduction loss at 40 A DC.
Q_g	140 nC - low total gate charge reduces driver power and switching transition time.
E_AS	350 mJ - single-pulse avalanche energy rating confirms ruggedness in unclamped inductive turn-off.
dv/dt	9 V/ns - high diode recovery dv/dt tolerance prevents spurious turn-on during commutation.
T_j max	175 °C - extended junction temperature range supports high ambient industrial environments.
R_thj-case	3.33 °C/W - enables 45 W dissipation at 25°C case temperature; requires mechanical mounting for thermal path.

Pinout & Package

STP80NF10FP uses the TO-220FP package: insulated tab (non-conductive mounting surface), vertical lead frame, 3-terminal configuration with standard pin spacing. The plastic body provides creepage/clearance compliant with 2500 V DC insulation rating.

Pin/Terminal	Circuit Role	Design Meaning
1 (Source)	Power return node for channel current	Low-impedance connection to ground/reference; tied to PCB ground plane for EMI control.
2 (Gate)	Control electrode for channel modulation	High-impedance input requiring <100 nA leakage; sensitive to ESD; routed away from noisy traces.
3 (Drain)	Main power output terminal	Connected to high-side switching node; electrically isolated from heatsink by package insulation.

Key Features

Feature	Design Value
STripFET™ II process	Reduces C_iss and Q_g vs. prior generations-enables higher frequency operation without sacrificing R_DS(on).
100% avalanche tested	Guarantees minimum 350 mJ E_AS per unit-eliminates need for external snubbers in flyback/LLC primary switches.
Insulated TO-220FP package	2500 V DC isolation between drain and heatsink-allows direct mounting to shared chassis without insulating pads.
High dv/dt immunity	9 V/ns rating ensures stable gate bias during fast voltage transients-critical for ZVS/ZCS resonant topologies.

Applications

Telecom DC-DC Converters

Server PSU Primary Switch

Use Scenario: 48 V input to 12 V/54 A isolated forward converter in telecom shelf power system.

IC Role / Device Role / Timing Role: Primary-side synchronous rectifier replacement; operated in hard-switched PWM mode at 200–500 kHz.

Use Value: 0.012 Ω R_DS(on) cuts conduction loss by >30% vs. legacy 0.022 Ω devices, improving full-load efficiency by 0.8%.

Use Scenario: 380 V DC input to 12 V/200 A LLC resonant converter in 2U rack-mount server PSU.

IC Role / Device Role / Timing Role: High-side switch in half-bridge configuration; handles 80 A peak drain current with 152 A pulsed rating.

Use Value: 140 nC Q_g reduces gate driver losses and enables use of lower-cost 2 A drivers instead of 4 A alternatives.

Industrial Motor Drives

UPS Inverter Stage

Use Scenario: 24–48 V DC bus driving 3-phase BLDC motor in HVAC blower module.

IC Role / Device Role / Timing Role: Low-side switching element in 3-phase inverter leg; switched at 10–20 kHz with PWM modulation.

Use Value: 175 °C max T_j and 3.33 °C/W R_thj-case allow sustained 38 A operation in sealed enclosures without forced air.

Use Scenario: 400 V DC bus in online double-conversion UPS delivering 3 kVA sine-wave output.

IC Role / Device Role / Timing Role: Output stage switch in full-bridge inverter; subjected to repetitive unclamped inductive stress during transfer switching.

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
IRF540NPBF	R_DS(on) = 0.044 Ω (typ), Q_g = 71 nC, V_DS = 100 V, TO-220 non-insulated	Lacks insulated tab and avalanche rating; lower voltage headroom in 48 V systems	Lower cost where heatsink isolation not required and avalanche stress is absent
IXTH80N10L2	R_DS(on) = 0.011 Ω (typ), Q_g = 120 nC, V_DS = 100 V, TO-247 insulated	Higher thermal performance (R_thj-case = 1.2 °C/W) but larger footprint and cost	Preferred for >100 W continuous dissipation where TO-220FP thermal limit is exceeded

Compared with IRF540NPBF and IXTH80N10L2, STP80NF10FP uniquely balances low R_DS(on), moderate Q_g, TO-220FP insulation, and guaranteed avalanche ruggedness-making it optimal for space-constrained, medium-power telecom/server SMPS where reliability under transient stress is critical.

FAQ

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

The STP80NF10FP supports 27 A continuous drain current at T_C = 100°C, as specified in Table 1 of the datasheet. This derating reflects thermal limits of the TO-220FP package and must be applied when heatsink temperature exceeds 25°C. Designers should verify junction temperature using R_thj-case = 3.33 °C/W and actual power dissipation.

Is the TO-220FP package electrically insulated?

Yes-the TO-220FP package features an insulated metal tab rated for 2500 V DC withstand voltage between drain and mounting surface. This allows direct attachment to grounded heatsinks without additional insulating hardware, simplifying thermal design and reducing assembly cost in high-voltage applications.

Does STP80NF10FP have a built-in body diode?

Yes-it includes an integral source-drain diode with 38 A continuous and 152 A pulsed current rating, 1.3 V forward voltage at 80 A, and 155 ns reverse recovery time at 150°C junction temperature. This diode supports freewheeling and synchronous rectification roles but is not optimized for ultra-fast recovery.

Can STP80NF10FP replace STP75NF75 in existing designs?

No-STP75NF75 is a 75 V, 75 A device with different R_DS(on) (0.0095 Ω), gate charge (160 nC), and safe operating area. STP80NF10FP has higher V_DS (100 V) but lower ID (38 A) and distinct SOA curves. Direct substitution requires verification of voltage margin, current demand, and thermal performance in the target circuit.
