Product details

Overview

IPN70R450P7SATMA1 from Infineon Technologies is a 700 V, 0.45 Ω R_DS(on) CoolMOS™ P7 superjunction N-channel power MOSFET in PG-SOT223 package, optimized for high-efficiency flyback converters in consumer chargers and LED lighting. It delivers 13.1 nC gate charge, 1.4 µJ E_oss at 400 V, and integrated ESD protection (HBM Class 2), operating up to 150 °C junction temperature.

For engineers reviewing the IPN70R450P7SATMA1 datasheet, IPN70R450P7SATMA1 pinout, IPN70R450P7SATMA1 application, or IPN70R450P7SATMA1 equivalent, key selection criteria include its low R_DS(on)×Q_g figure-of-merit, dv/dt ruggedness (100 V/ns), thermal resistance (R_thJS = 17.7 °C/W), and suitability for cost-sensitive 65–100 W offline SMPS designs.

Technical Context

This device implements Infineon's CoolMOS™ P7 superjunction architecture with optimized charge balancing for reduced conduction and switching losses. Its gate threshold voltage (V_GS(th) = 3 V typ) enables reliable turn-on with standard 10 V gate drivers, while the 4.4 V gate plateau supports stable Miller region control during hard-switching.

The MOSFET integrates a fast-recovery body diode (t_rr = 200 ns, Q_rr = 0.7 µC) and exhibits robust dv/dt immunity (100 V/ns) in high-side configurations. Thermal design is supported by low R_thJS (17.7 °C/W) and validated operation up to T_j = 150 °C under pulsed drain current (I_D,pulse = 26 A).

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	700 V - Withstands full mains rectified voltage (e.g., 385 V DC bus + margin) in universal-input flyback converters
R_DS(on), max	0.45 Ω @ T_j = 25 °C - Enables <1.5 W conduction loss at 2.3 A RMS in 65 W adapter designs
Q_g, typ	13.1 nC - Reduces gate drive power and allows use of low-cost 100 mA gate drivers
E_oss	1.4 µJ @ 400 V - Low output energy minimizes turn-off loss and improves efficiency above 100 kHz
V_GS(th), typ	3 V - Ensures clean turn-on with standard 5 V logic-level controllers without level-shifting
ESD Class	HBM Class 2 (≥2 kV) - Integrated protection reduces need for external TVS on gate traces
T_j max	150 °C - Supports compact heatsinking in slim-profile adapters and enclosed LED drivers

Pinout & Package

Package: PG-SOT223 (standard SOT-223 outline with exposed drain tab for thermal enhancement). Pin 1: Gate; Pin 2: Drain (connected to metal tab); Pin 3: Source.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Gate)	Control terminal	Receives PWM signal; low input capacitance (C_iss = 424 pF) eases driver selection
Pin 2 (Drain)	High-voltage power input	Connected to transformer primary and rectified AC bus; tab provides low-inductance thermal path
Pin 3 (Source)	Power return / reference node	Serves as local ground for gate driver; requires low-impedance PCB trace to minimize ringing

Key Features

Feature	Design Value
Ultra-low R_DS(on) × Q_g	Enables >90% efficiency in 65 W USB-C adapters at 100 kHz without active cooling
Integrated ESD protection diode	Eliminates need for discrete gate Zener clamps in production assemblies
Low E_oss (1.4 µJ)	Reduces turn-off loss by ~35% vs. prior P6 generation, enabling higher-frequency operation
100 V/ns dv/dt ruggedness	Prevents false turn-on in high-side flyback or LLC resonant topologies with fast voltage transients
Thermal resistance R_thJS = 17.7 °C/W	Allows 7.1 W dissipation with ≤130 °C case rise, supporting 2-layer FR4 PCBs without heatsinks

Applications

USB-C Wall Charger

Use Scenario: 65 W universal-input flyback converter powering USB-C PD devices with no fan and <15 mm profile.

IC Role / Device Role / Timing Role: Primary-side high-voltage switch handling 400 V DC bus and delivering 1.7 A peak primary current at 120 kHz.

Use Value: Low R_DS(on) and E_oss enable >92% average efficiency across 5–26 V output range while maintaining <60 °C surface temperature.

Use Scenario: Dimmable constant-current LED driver for commercial downlights operating from 120/230 V AC mains.

IC Role / Device Role / Timing Role: Primary-side switching element in quasi-resonant flyback topology with valley-switching control.

Use Value: Fast body diode recovery (t_rr = 200 ns) and low Q_gd (5.0 nC) reduce switching noise and improve EMI compliance without snubbers.

TV Power Supply

AC-DC Adapter for Audio Equipment

Use Scenario: Auxiliary 12 V standby supply in 55-inch LCD TV with strict no-load power (<300 mW) requirement.

IC Role / Device Role / Timing Role: High-voltage switch in burst-mode flyback operating at <20 kHz during standby.

Use Value: Low I_DSS (<1 µA at 700 V) and tight V_GS(th) distribution (2.5–3.5 V) ensure stable light-load regulation and minimal standby loss.

Use Scenario: Compact 18 V/3 A adapter for premium headphones and DACs requiring ultra-low audible noise.

IC Role / Device Role / Timing Role: Main power switch in fixed-frequency flyback with synchronous rectification on secondary side.

Use Value: Low C_oss (8 pF) and Co(er) (21 pF) minimize capacitive coupling into audio ground, reducing buzz/hum in sensitive analog circuits.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-voltage power MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STP7NK80ZFP	800 V rating, higher R_DS(on) (0.85 Ω), no integrated ESD diode, TO-220FP package	Requires external gate protection; less suitable for slim SMT-only designs	Preferred where higher voltage margin is needed and through-hole assembly is acceptable
IPP60R099P7XKSA1	Same P7 platform, lower R_DS(on) (0.099 Ω), DPAK package, higher Q_g (32 nC)	Better for higher-power (>100 W) designs but increases gate drive complexity	Select when thermal headroom is constrained and board space allows larger DPAK footprint

Compared with STP7NK80ZFP and IPP60R099P7XKSA1, IPN70R450P7SATMA1 offers optimal balance of voltage rating, conduction loss, gate drive simplicity, and SMT manufacturability for sub-100 W consumer power supplies-making it ideal for cost-sensitive, space-constrained applications where reliability and ease of use are critical.

FAQ

What is the maximum continuous drain current for IPN70R450P7SATMA1 at 100 °C case temperature?

The maximum continuous drain current is 6.5 A at T_C = 100 °C, as specified in Table 2 of the datasheet. This rating is thermally limited by junction temperature (T_j,max = 150 °C) and assumes proper PCB copper area for heat dissipation. At T_C = 25 °C, the rating rises to 10.0 A.

Does IPN70R450P7SATMA1 require an external gate resistor for stability in flyback applications?

Yes-a gate resistor (typically 5.3–22 Ω) is recommended to dampen ringing and control switching speed. The datasheet specifies timing parameters (e.g., t_r, t_f) using R_G = 5.3 Ω, and ferrite beads are advised when paralleling multiple units to prevent oscillation.

Can IPN70R450P7SATMA1 be used in continuous conduction mode (CCM) flyback designs?

Yes-it supports CCM operation due to its robust avalanche rating (I_AS = 3.5 A single-pulse) and low reverse recovery charge (Q_rr = 0.7 µC). However, careful attention to snubber design and transformer leakage inductance is required to manage voltage overshoot during demagnetization.

Is the PG-SOT223 package lead-free and RoHS-compliant?

Yes-the IPN70R450P7SATMA1 package is lead-free and fully RoHS-compliant per EU Directive 2011/65/EU and REACH SVHC regulations. The "ATMA1" suffix denotes tape-and-reel packaging with standard moisture sensitivity level (MSL1) and 260 °C peak reflow compatibility.
