Product details

Overview

STP150NF04 from STMicroelectronics is an N-channel enhancement-mode Power MOSFET in TO-220 package, rated for 40 V V_DS, 80 A continuous drain current, and 5 mΩ typical R_DS(on) at V_GS = 10 V. It features 100% avalanche tested ruggedness and low gate charge (118 nC), making it suitable as a primary switch in high-efficiency isolated DC-DC converters for telecom and server power supplies.

For engineers reviewing the STP150NF04 datasheet, STP150NF04 pinout, STP150NF04 application, or STP150NF04 equivalent, key selection criteria include its 0.5 °C/W junction-to-case thermal resistance, 320 A pulsed drain capability, 73 ns reverse recovery time, and compatibility with standard-level gate drive circuits.

Technical Context

This device employs ST's STripFET™ II process to minimize input capacitance (C_iss = 3650 pF) and gate charge-critical for high-frequency switching in hard-switched topologies. Its low R_DS(on) and high current rating support conduction efficiency in primary-side SMPS switches operating up to 200 kHz.

The integrated source-drain diode exhibits 1.3 V forward voltage at 80 A and 73 ns reverse recovery time at 150 °C, enabling robust body-diode operation in synchronous rectification or freewheeling paths without external diode supplementation.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	40 V - Maximum blocking voltage compatible with 36 V nominal bus systems and 48 V telecom inputs
R_DS(on) typ.	5 mΩ at V_GS = 10 V - Enables ≤ 32 W conduction loss at 80 A, reducing heatsink requirements
I_D cont.	80 A at T_C = 25 °C - Supports high-current primary-side switching in 500–1000 W DC-DC stages
Q_g	118 nC - Low gate drive energy enables use with standard PWM controllers (e.g., UC384x, UCC28xx)
R_th(j–case)	0.5 °C/W - Allows direct mounting to heatsink for thermal management without thermal interface layer derating
E_AS	0.6 J - Single-pulse avalanche energy supports unclamped inductive switching in flyback or forward converters

Pinout & Package

TO-220 package with vertical metal tab (pin 3), non-isolated case. Standard three-terminal configuration: Gate (pin 1), Drain (pin 2), Source (pin 3 / tab).

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Left)	Gate	Control terminal requiring ≤ ±20 V drive; 100 nA leakage ensures stable turn-off under high-impedance bias
Pin 2 (Middle)	Drain	Main high-side switching node; electrically connected to metal tab - requires isolation when mounted to heatsink
Pin 3 / Tab (Right)	Source	Power return path and reference for gate drive; low-inductance connection critical for minimizing switching oscillation

Key Features

Feature	Design Value
100% avalanche tested	Guarantees robustness against inductive kickback in unclamped switching events without derating
Low gate charge (118 nC)	Reduces driver power dissipation and enables higher frequency operation without gate driver oversizing
STripFET™ II process	Delivers 30% lower C_iss vs legacy planar MOSFETs, improving EMI profile and dv/dt immunity
Standard-level gate drive	Operates fully enhanced with 10 V logic-compatible drive - eliminates need for level-shifting or bootstrap circuitry

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
IRF1404	R_DS(on) = 4 mΩ (typ), Q_g = 131 nC, V_DS = 40 V - slightly lower on-resistance but higher gate charge	Higher gate drive power required; less suitable for high-frequency (>150 kHz) designs	Prefer when lowest conduction loss dominates over switching loss in <100 kHz applications
STP16NF06	V_DS = 60 V, R_DS(on) = 0.05 Ω (typ), I_D = 16 A - higher voltage rating but significantly higher on-resistance and lower current	Not suitable for 80 A primary-side switching; limited to auxiliary or low-power stages	Select only if 60 V blocking and smaller footprint (TO-220FP) are prioritized over current capacity

Compared with IRF1404 and STP16NF06, STP150NF04 delivers optimal balance of low R_DS(on), moderate Q_g, and high current capability - making it uniquely suited for 40 V, >50 A primary-side switching where thermal density and gate drive simplicity are critical.

FAQ

Is STP150NF04 suitable for synchronous rectification?

Yes - its 1.3 V V_SD at 80 A and 73 ns t_rr support efficient body-diode conduction and fast recovery in secondary-side synchronous rectification. However, dedicated SR controllers (e.g., STSR3) are recommended to manage gate timing precisely and avoid shoot-through.

What is the maximum safe operating temperature for continuous operation?

The maximum junction temperature is 175 °C, but continuous operation above 150 °C requires derating per the 2 W/°C derating factor. With R_th(j–case) = 0.5 °C/W and 300 W P_tot, sustained 80 A operation demands case temperature ≤ 110 °C to maintain T_j < 150 °C.

Does STP150NF04 require a gate resistor for stability?

Yes - a 4.7 Ω gate resistor is specified in the datasheet for switching time characterization and EMI control. Omitting it risks ringing, overshoot, and potential gate oxide stress due to parasitic L_g/C_iss resonance, especially at >100 kHz.

Can STP150NF04 be used in parallel configurations?

Yes - its positive temperature coefficient of R_DS(on) (confirmed in Figure 11) enables inherent current sharing. For reliable paralleling, match devices within 5% R_DS(on), use symmetrical PCB layout, and ensure identical gate drive impedance to each unit.
