Product details
Overview
IPS70R1K4P7SAKMA1 from Infineon Technologies is a 700 V, 1.4 Ω RDS(on) CoolMOS™ P7 superjunction power MOSFET in PG-TO251-3 (IPAK SL) package, with drain-connected tab, gate on pin 1, and source on pin 3. It delivers 4.7 nC total gate charge, 0.6 µJ Eoss at 400 V, and 8.2 A pulsed drain current - optimized for high-efficiency, high-power-density flyback converters in consumer adapters and LED lighting.
For engineers reviewing the IPS70R1K4P7SAKMA1 datasheet, IPS70R1K4P7SAKMA1 pinout, IPS70R1K4P7SAKMA1 application, or IPS70R1K4P7SAKMA1 equivalent, key selection criteria include its 700 V VDS, low RDS(on)×Qg figure-of-merit, integrated ESD protection (HBM Class 1C), thermal resistance of 5.5 °C/W (junct-to-case), and validated performance in 65–100 kHz flyback topologies with <150 °C max junction temperature.
Technical Context
This CoolMOS™ P7 device implements a superjunction structure enabling fast switching while maintaining low conduction losses. Its 3 V typical gate threshold voltage and 4.3 V gate plateau support robust drive margin in fixed-frequency flyback controllers with 12–15 V gate drive.
The MOSFET integrates an intrinsic body diode with 0.9 V forward voltage at 0.9 A and 130 ns reverse recovery time, suitable for discontinuous conduction mode (DCM) operation. Its dv/dt ruggedness of 100 V/ns ensures reliable operation under high-slew-rate conditions in compact, high-voltage secondary-side snubberless designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 700 V - supports universal AC input (85–265 VAC) with ≥2× safety margin in 400 V DC-link flyback designs |
| RDS(on),max | 1.4 Ω @ Tj=150°C - enables <1.5 W conduction loss at 1.2 A RMS in 30 W adapter applications |
| Qg,typ | 4.7 nC - allows efficient 100 kHz switching with <0.5 W gate drive loss using standard 10 Ω gate resistor |
| Eoss | 0.6 µJ @ 400 V - reduces turn-off energy loss by >40% vs. prior CoolMOS™ P6 generation at same voltage/current |
| RthJC | 5.5 °C/W - permits 22.7 W power dissipation at 25°C case temperature, supporting thermally constrained IPAK SL PCB layouts |
| VGS(th),typ | 3 V - ensures reliable turn-on with standard PWM controller gate drivers (e.g., UC384x, VIPer series) |
| ESD Class | HBM Class 1C (1 kV) - provides production-line handling robustness without external protection circuitry |
Pinout & Package
IPS70R1K4P7SAKMA1 uses the PG-TO251-3 (IPAK SL) package with exposed drain-connected copper tab for enhanced thermal transfer. The plastic body measures 6.5 mm × 6.2 mm × 2.3 mm, and the tab is electrically connected to pin 2 (Drain).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Gate | Control terminal requiring low-impedance drive path; sensitive to layout-induced ringing due to low Qgd/Qgs ratio |
| Pin 2 / Tab | Drain | Main high-voltage power terminal; tab must be soldered to large copper pour for thermal management and EMI reduction |
| Pin 3 | Source | Reference node for gate drive and current sensing; connects to primary ground plane with minimal loop area |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low RDS(on)×Qg FOM | 6.58 Ω·nC - enables >90% efficiency at 30 W output in 100 kHz flyback with minimal heatsinking |

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 |
|---|---|---|---|
| STP7NK70ZFP | 700 V, 0.95 Ω RDS(on), 12.5 nC Qg, TO-220FP package | Higher conduction loss but higher peak current capability (7 A continuous); requires larger heatsink | Prefer when board space allows TO-220FP and design prioritizes ruggedness over power density |
| IPP60R1K4P7XKSA1 | Same P7 die, but in TO-220 package with isolated tab; identical RDS(on), Qg, Eoss | Requires insulating washer and mounting hardware; 10.5 °C/W RthJC limits power handling vs. IPAK SL | Choose only if isolation from heatsink is mandatory and thermal budget permits 40% lower power dissipation |
Compared with STP7NK70ZFP and IPP60R1K4P7XKSA1, IPS70R1K4P7SAKMA1 offers the lowest thermal resistance and smallest footprint among 700 V/1.4 Ω devices, making it optimal for space-constrained, thermally aggressive consumer power supplies where PCB real estate and enclosure volume are premium.

FAQ
What is the maximum recommended gate resistor value for reliable switching at 100 kHz?
A 10.2 Ω gate resistor is validated in the datasheet for 100 kHz operation with 400 V VDD and 0.5 A test current. Using >15 Ω increases turn-off time beyond safe SOA limits in DCM flyback, risking avalanche stress. For 65 kHz designs, 22 Ω is acceptable with verified gate drive voltage margin above 4.3 V plateau.
Can IPS70R1K4P7SAKMA1 be paralleled in a single-stage PFC front-end?
No - this part is not characterized or qualified for continuous conduction mode (CCM) PFC use. Its RDS(on) temperature coefficient is positive but insufficient for stable current sharing above 70 °C junction temperature. Parallel operation is only recommended in DCM flyback with individual gate ferrite beads per device, as noted in the application note AN-CoolMOSTM 700V P7.
Does the integrated body diode support synchronous rectification in secondary-side circuits?
No - the body diode is optimized for flyback freewheeling, not synchronous rectification. Its 130 ns trr and 0.4 µC Qrr cause excessive switching loss if used as a controlled rectifier. Dedicated SR controllers require MOSFETs with <30 ns trr and <0.1 µC Qrr; this device lacks those characteristics.
Is the drain tab electrically isolated from the package mold compound?
No - the drain tab is metallurgically bonded to pin 2 and forms the primary drain connection. It is not isolated; the entire tab must be treated as live 700 V potential. Insulation requirements must be met externally via PCB clearance, conformal coating, or mechanical barriers - no internal isolation is provided.
