Product details

Overview

IPLK70R750P7ATMA1 from Infineon Technologies is a 700 V, 750 mΩ CoolMOS™ P7 superjunction power MOSFET in PG-TDSON-8 package, designed for high-efficiency SMPS in industrial and server power supplies. It delivers R_DS(on) × Q_g = 14.3 Ω·nC, 100% avalanche-rated (E_AS = 92 mJ at T_j = 25°C), and qualified per JEDEC for industrial applications.

For engineers reviewing the IPLK70R750P7ATMA1 datasheet, IPLK70R750P7ATMA1 pinout, IPLK70R750P7ATMA1 application, or IPLK70R750P7ATMA1 equivalent, key selection criteria include R_DS(on), gate charge, avalanche ruggedness, thermal resistance (R_thJC = 1.2 K/W), and MSL Level 1 reflow compatibility.

Technical Context

This device employs CoolMOS™ P7 technology with optimized charge balance and reduced gate-drain charge (Q_gd = 11 nC), enabling high-frequency operation up to 300 kHz in LLC resonant converters. Its low C_iss (470 pF) and C_oss (65 pF) minimize switching losses during zero-voltage switching transitions.

The MOSFET supports hard-switched topologies including flyback and PFC boost stages, with guaranteed unclamped inductive switching (UIS) capability and gate oxide robustness validated under ±20 V HTGB stress for 1000 h at 150°C.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	700 V - Enables use in universal-input offline SMPS without derating.
R_DS(on) max	750 mΩ @ V_GS = 10 V, T_j = 25°C - Sets conduction loss floor in 100–300 W industrial adapters.
Q_g	19 nC - Determines gate driver current requirement and turn-on energy loss.
E_AS	92 mJ @ T_j = 25°C - Supports reliable operation under transient overloads in UPS and motor drives.
R_thJC	1.2 K/W - Enables 100% thermal derating margin at 1.5 A continuous drain current in PCB-mounted TDSON-8 layout.
MSL Level	Level 1, 260°C - Allows single-pass lead-free reflow without moisture sensitivity concerns.

Pinout & Package

Package: PG-TDSON-8 (exposed drain pad, 5 mm × 6 mm footprint, 0.95 mm height), RoHS-compliant, halogen-free.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 3, 4, 5, 7, 8	Drain (D)	Internally connected to exposed thermal pad - must be soldered to large copper pour for thermal and electrical performance.
6	Source (S)	Reference node for gate drive and current sensing; low-inductance connection critical for EMI control.
G	Gate (G)	Control terminal requiring <19 nC charge; sensitive to ESD (HBM Class 1C, CDM Class C3).

Key Features

Feature	Design Value
Optimized R_DS(on) × Q_g	14.3 Ω·nC - Reduces total switching + conduction loss in 100–250 kHz PFC stages.
100% UIS tested	E_AS = 92 mJ - Eliminates need for external snubbers in flyback primary switches.
JEDEC-qualified reliability	HTRB/HTGB/TC passed at 150°C - Ensures >10-year field life in industrial 24/7 power systems.
Low C_oss energy	E_oss = 1.2 µJ @ V_DS = 400 V - Minimizes dead-time losses in half-bridge LLC resonant converters.

Applications

Industrial SMPS

Server PSU

Use Scenario: 200 W open-frame power supply for PLC controllers operating continuously at 60°C ambient.

IC Role / Device Role / Timing Role: Primary-side switching transistor in active-clamp forward topology.

Use Scenario: 80 PLUS Titanium-certified 1.5 kW server power supply with digital PFC + LLC stage.

IC Role / Device Role / Timing Role: PFC boost switch operating at 70 kHz with valley-switching control.

Use Value: Low Q_gd/Q_g ratio reduces Miller-induced shoot-through risk and improves light-load efficiency.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
IPW65R095C7	R_DS(on) = 95 mΩ, V_DSS = 650 V, Q_g = 44 nC - higher conduction loss but lower switching loss at >200 kHz.	Better suited for high-frequency resonant converters where gate drive loss dominates.	Select when operating frequency exceeds 250 kHz and R_DS(on) derating above 100°C is acceptable.
STP70N10F7	R_DS(on) = 100 mΩ, V_DSS = 700 V, Q_g = 32 nC - higher Q_g increases gate drive power and slows switching edge.	Requires larger gate driver and more aggressive EMI filtering due to slower dV/dt.	Prefer only if legacy design reuse mandates TO-220 footprint and thermal mass is available.

Compared with IPW65R095C7 and STP70N10F7, IPLK70R750P7ATMA1 offers the lowest R_DS(on) × Q_g product in its voltage class, making it optimal for space-constrained industrial adapters where thermal headroom is limited and gate drive efficiency matters.

FAQ

What is the maximum continuous drain current (I_D) for IPLK70R750P7ATMA1 at T_c = 100°C?

The maximum continuous drain current is 4.5 A when case temperature is maintained at 100°C, based on thermal limits defined by R_thJC = 1.2 K/W and maximum junction temperature of 150°C. This rating assumes full solder coverage of the exposed drain pad to a 10 cm² copper area on a 2-layer PCB.

Does IPLK70R750P7ATMA1 support paralleling for higher current capacity?

Yes - its positive temperature coefficient of R_DS(on) enables stable current sharing across parallel devices. Designers must match gate loop inductance and use Kelvin source connections to avoid oscillation; typical layout uses symmetrical gate routing and shared gate resistor networks.

Is IPLK70R750P7ATMA1 compliant with JEDEC JESD47 for automotive applications?

No - it is qualified per JEDEC JESD47 only for industrial applications (not AEC-Q101). For automotive use, Infineon recommends the AEC-Q101-qualified IPA60R099P7XKSA1, which shares the same die but adds extended temperature screening and bias testing.

What is the recommended gate resistor value for hard-switched PFC operation at 70 kHz?

A 10 Ω non-inductive gate resistor is recommended to limit peak gate current to <1.5 A while maintaining <50 ns turn-on delay. This value balances switching speed against ringing suppression and EMI compliance in 3.3 kW PFC stages using UCC28070 controllers.
