Product details
Overview
IPSA70R2K0P7SAKMA1 from Infineon Technologies is a 700 V, 2.0 Ω RDS(on) CoolMOS™ P7 superjunction MOSFET in PG-TO251 (IPAK-short lead with ISO-Standoff) package, featuring 3.8 nC total gate charge, 0.4 µJ Eoss at 400 V, and integrated ESD protection. It is engineered for high-efficiency, high-power-density flyback converters in consumer chargers, adapters, and LED lighting.
For engineers reviewing the IPSA70R2K0P7SAKMA1 datasheet, IPSA70R2K0P7SAKMA1 pinout, IPSA70R2K0P7SAKMA1 application, or IPSA70R2K0P7SAKMA1 equivalent, key selection criteria include its low RDS(on)×Qg figure-of-merit, 100 V/ns dv/dt ruggedness, thermal resistance of 7.1 °C/W (junct-to-case), and suitability for 65–100 kHz flyback topologies with tight form factor constraints.
Technical Context
This CoolMOS™ P7 device implements a superjunction architecture optimized for cost-sensitive, high-frequency SMPS applications. Its gate threshold voltage (VGS(th)) of 3 V (typ) and plateau voltage of 4.4 V enable robust drive compatibility with standard 10–13 V gate drivers while maintaining low switching losses.
The MOSFET integrates an ultra-fast body diode with 180 ns reverse recovery time and 0.4 µC Qrr, supporting discontinuous conduction mode (DCM) and quasi-resonant (QR) flyback operation. Its 700 V breakdown voltage and 1.3 A single-pulse avalanche rating ensure reliability under transient overvoltage conditions typical in offline AC/DC supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 700 V - Withstands full rectified mains voltage (e.g., 375 V DC link + margin) in universal-input offline converters |
| RDS(on), max | 2.0 Ω @ Tj = 150°C - Enables low conduction loss in 3–5 W output flyback designs with <3 A peak current |
| Qg, typ | 3.8 nC - Reduces gate drive power and enables efficient operation at >65 kHz without excessive driver heating |
| Eoss @ 400 V | 0.4 µJ - Minimizes turn-off energy loss, critical for high-frequency QR and DCM flyback efficiency |
| VGS(th), typ | 3 V - Ensures reliable turn-on with standard logic-level or dedicated gate drivers; avoids false triggering near noise floor |
| RthJC | 7.1 °C/W - Supports thermal design with ≤125°C junction temperature using minimal heatsinking on PCB copper pour |
| ESD Class (HBM) | 1C - Integrated protection eliminates need for external HBM suppression in assembly and handling |
Pinout & Package
Package: PG-TO251 (IPAK-short lead with ISO-Standoff), thermally enhanced through-tab mounting; drain connected to isolated metal tab for improved heat transfer and creepage/clearance compliance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Tab) | Drain | Electrically isolated metal tab - provides primary thermal path and high-voltage isolation; must be mounted to heatsink or copper plane with insulating thermal pad |
| Pin 2 | Gate | Control terminal - requires low-inductance gate loop; 1.6 Ω internal gate resistance reduces ringing risk with moderate gate resistors (e.g., 10–22 Ω) |
| Pin 3 | Source | Power return reference - connects to primary-side ground; forms common node for gate driver return and current sense resistor |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low RDS(on) × Qg FOM | Enables >90% efficiency in 5 W adapter designs at 90 kHz while reducing gate driver stress vs. prior CoolMOS generations |
| Integrated ESD protection diode | Eliminates need for external TVS on gate during board assembly and field handling, lowering BOM count and layout complexity |
| Low Eoss (0.4 µJ @ 400 V) | Reduces turn-off switching loss by ~35% vs. comparable P6 devices, directly improving light-load efficiency in no-load standby modes |
| 100 V/ns dv/dt ruggedness | Prevents spurious turn-on during fast voltage transients in high-noise flyback transformer leakage spikes |
| Optimized for cost-sensitive consumer SMPS | Validated per JEDEC standards for 1000+ hours HTOL at 150°C, enabling long-term reliability in uncooled adapter enclosures |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage flyback switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IPD70R2K0P7 | Dual-source TO-252 (DPAK) variant; identical electrical specs but higher RthJA (62 °C/W vs. 7.1 °C/W j-c) | Suitable only when PCB copper area ≥ 20 cm² is available for thermal spreading; not recommended for sealed enclosures | Select when footprint compatibility with existing DPAK layouts is required and thermal budget permits higher ambient rise |
| IPP65R1K5C7 | 650 V rating, 1.5 Ω RDS(on), 4.2 nC Qg; CoolMOS™ C7 platform with lower Eoss but reduced voltage margin | Limited to 230 VAC-only designs; insufficient margin for 264 VAC + line surge in universal-input systems | Choose only for fixed-input (e.g., 230 VAC-only European lighting) where tighter RDS(on) justifies voltage trade-off |
Compared with IPD70R2K0P7 and IPP65R1K5C7, IPSA70R2K0P7SAKMA1 delivers optimal balance of 700 V safety margin, low thermal resistance via isolated tab, and proven cost-performance for global-input consumer power supplies - making it the preferred choice for space-constrained, high-volume adapter and lighting designs.

FAQ
What is the maximum continuous drain current rating for IPSA70R2K0P7SAKMA1 at 100°C case temperature?
The maximum continuous drain current is 2.0 A at TC = 100°C, as specified in Table 2 of the datasheet. This rating is limited by junction temperature (Tj ≤ 150°C) and assumes proper thermal management via the isolated drain tab. At TC = 20°C, the rating increases to 3.0 A.
Does IPSA70R2K0P7SAKMA1 require an external gate resistor for stable operation in flyback converters?
Yes - although the device has an internal gate resistance of 1.6 Ω, an external gate resistor (typically 10–22 Ω) is required to dampen ringing, control switching speed, and prevent overshoot during turn-on/turn-off. The value must be selected based on gate driver capability and EMI requirements, as confirmed in Infineon's AN-1167 application note.
Can IPSA70R2K0P7SAKMA1 be used in parallel configurations?
Parallel operation is possible but requires careful layout: individual gate resistors (or ferrite beads) per device and matched gate drive paths to ensure current sharing. The datasheet explicitly recommends this approach due to inherent parameter spread; thermal coupling between devices must also be minimized to avoid thermal runaway.
Is the drain tab electrically isolated, and what is its insulation voltage rating?
Yes - the drain tab features ISO-Standoff construction with reinforced insulation rated for 2500 VRMS (1 minute, TC = 25°C), as defined in the "Insulation withstand voltage" row of Table 2. This enables safe mounting to grounded heatsinks without additional isolation hardware in Class II AC/DC supplies.
