Product details

Overview

IPS70R900P7SAKMA1 from Infineon Technologies is a 700 V, 0.9 Ω R_DS(on) max, 6.8 nC Q_g, TO-251-3 (IPAK SL) packaged CoolMOS™ P7 superjunction MOSFET optimized for flyback converters in cost-sensitive consumer power supplies. It delivers low E_oss (0.9 µJ @ 400 V), integrated ESD protection (HBM Class 1C), and excellent thermal behavior (R_thJC = 4.1 °C/W) for high-efficiency, slim-form-factor chargers and LED drivers.

For engineers reviewing the IPS70R900P7SAKMA1 datasheet, IPS70R900P7SAKMA1 pinout, IPS70R900P7SAKMA1 application, or IPS70R900P7SAKMA1 equivalent, this page provides verified technical context, validated pin functions, real-world application mapping for flyback topologies, and confirmed alternative parts with documented parameter-level differences.

Technical Context

This CoolMOS™ P7 device implements a superjunction architecture enabling high-voltage blocking (700 V) with ultra-low conduction and switching losses-evidenced by R_DS(on) × Q_g and R_DS(on) × E_oss figures of merit. Its gate threshold voltage (V_GS(th) = 3 V typ.) and plateau voltage (4.4 V) support reliable turn-on with standard 10–13 V gate drivers.

The MOSFET integrates an intrinsic body diode with t_rr = 160 ns and Q_rr = 0.5 µC at 400 V, enabling efficient discontinuous conduction mode (DCM) operation in flyback designs. Its dv/dt ruggedness (100 V/ns) and avalanche rating (I_AS = 3.6 A) ensure robustness under transient overvoltage and transformer leakage spikes.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	700 V - Supports universal input (85–265 V_AC) flyback designs with sufficient margin against reflected output voltage plus leakage spikes.
R_DS(on), max	0.9 Ω @ T_j = 25°C - Enables low conduction loss in 15–30 W adapters without forced cooling.
Q_g, typ	6.8 nC - Reduces gate drive power and enables use of low-cost, low-current gate drivers (e.g., <100 mA peak).
E_oss @ 400 V	0.9 µJ - Low stored output capacitance energy minimizes switching loss at >100 kHz frequencies, supporting high-density layouts.
T_j max	150 °C - Allows operation in thermally constrained enclosures (e.g., wall-wart adapters) with derated current (3.5 A @ T_C = 100°C).
R_thJC	4.1 °C/W - Enables direct heatsinking via PCB copper pour or small external metal tab, critical for IPAK SL's exposed drain pad.
ESD Class	HBM Class 1C (1 kV) - Integrated Zener-protected gate withstands handling and board assembly without external clamping.

Pinout & Package

IPS70R900P7SAKMA1 uses the PG-TO251-3 (IPAK SL) package with an exposed drain pad on the underside for thermal conduction. The leadframe design places Drain (Pin 2 + Tab), Gate (Pin 1), and Source (Pin 3) in a single-row configuration compatible with through-hole and surface-mount assembly.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1	Gate	Control terminal requiring 10–13 V drive; low C_iss (211 pF) and Q_gd (2.6 nC) enable fast, low-loss switching.
Pin 2 + Tab	Drain	Main high-voltage power terminal; exposed metal tab serves as primary thermal path to PCB copper or heatsink.
Pin 3	Source	Reference node for gate drive and current sensing; connects to primary ground return path in flyback circuits.

Key Features

Feature	Design Value
Ultra-low FOM R_DS(on) × Q_g	0.9 Ω × 6.8 nC = 6.12 Ω·nC - Directly reduces total switching + conduction loss in 65–130 kHz flyback converters.
Low E_oss (0.9 µJ @ 400 V)	Reduces turn-off loss by ~30% vs. prior P6 generation - enables higher frequency operation without efficiency penalty.
Integrated ESD protection diode	HBM Class 1C (1 kV) - Eliminates need for external gate protection components in production assemblies.
Optimized dv/dt ruggedness (100 V/ns)	Withstands rapid voltage transients during MOSFET turn-off in transformer-coupled topologies without false triggering.
Thermal resistance R_thJC = 4.1 °C/W	Allows 30.5 W power dissipation at T_C = 25°C - supports compact PCB layout with minimal copper area.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-voltage flyback switch applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IPP60R900P7XKMA1	Same P7 die in TO-220FP package; R_thJC = 3.5 °C/W (lower), but larger footprint and no exposed drain tab.	Better thermal performance in open-frame supplies; unsuitable for ultra-slim sealed adapters due to height and mounting constraints.	Select when board space allows TO-220FP and junction temperature margin is critical above 125°C.
IPD70R900P7SAKMA1	Same P7 die in TO-252 (DPAK) package; R_thJC = 5.2 °C/W (higher); same pinout orientation but smaller thermal pad area.	Lower profile than IPAK SL but reduced thermal capability; requires larger copper pour to match 4.1 °C/W performance.	Select when SMT-only assembly is required and thermal budget permits 2–3°C/W higher R_thJC.

Compared with IPP60R900P7XKMA1 and IPD70R900P7SAKMA1, IPS70R900P7SAKMA1 uniquely balances ultra-low thermal resistance (4.1 °C/W), compact IPAK SL footprint, and through-hole/SMT flexibility-making it optimal for space-constrained, cost-driven consumer adapters where thermal path optimization is achieved via PCB copper rather than external heatsinks.

FAQ

What is the maximum continuous drain current for IPS70R900P7SAKMA1 at 100°C case temperature?

The maximum continuous drain current is 3.5 A at T_C = 100°C, as specified in Table 2 of the Rev. 2.1 datasheet. This rating is limited by junction temperature (T_j ≤ 150°C) and assumes proper PCB copper thermal relief per Infineon's recommended land pattern for IPAK SL.

Does IPS70R900P7SAKMA1 require a gate resistor for stable operation in flyback converters?

Yes-a gate resistor (typically 5.3 Ω, per datasheet test conditions) is required to dampen ringing, control dV/dt, and prevent spurious turn-on due to Miller coupling. The device's low Q_gd (2.6 nC) makes it sensitive to fast voltage transients without appropriate gate impedance.

Can IPS70R900P7SAKMA1 be paralleled with identical units in high-power designs?

Parallel operation is feasible but requires gate ferrite beads or individual totem-pole drivers per unit to balance dynamic current sharing. The datasheet explicitly recommends this approach due to inherent parameter spread (e.g., ±20% R_DS(on)) and thermal coupling effects in shared PCB copper.

Is the body diode suitable for synchronous rectification in secondary-side applications?

No-the integrated body diode has t_rr = 160 ns and Q_rr = 0.5 µC, making it unsuitable for synchronous rectification. It is designed for freewheeling in primary-side flyback operation only; external Schottky or MOSFET synchronous rectifiers are required on the secondary side.
