Product details
Overview
IPLK80R1K2P7ATMA1 from Infineon is an 800V superjunction N-channel MOSFET in ThinPAK 5x6 package, featuring Kelvin source configuration, 1.2 Ω max RDS(on) at 10 V VGS, 11 nC total gate charge, and integrated Zener ESD protection. It serves as a high-voltage switching device in flyback converters for low-power AC/DC adapters and chargers.
For engineers reviewing the IPLK80R1K2P7ATMA1 datasheet, IPLK80R1K2P7ATMA1 pinout, IPLK80R1K2P7ATMA1 application, or IPLK80R1K2P7ATMA1 equivalent, key selection criteria include its 3 V gate threshold with ±0.5 V variation, 800 V VDS rating, Kelvin-source layout for accurate current sensing, and JEDEC-qualified industrial reliability.
Technical Context
This CoolMOS™ P7 device uses charge compensation technology to achieve best-in-class figure-of-merit (RDS(on) × Eoss) of 1.2 Ω × 1.0 µJ. Its internal Kelvin source (Pin 3) separates sense and power return paths, enabling precise gate drive control and minimizing source inductance effects during fast switching.
The MOSFET integrates a Zener diode for ESD protection (HBM Class 2), supports hard and soft switching topologies, and exhibits 100 V/ns dv/dt ruggedness. Thermal resistance is 2.9 °C/W (junction-to-case), optimized for PCB-mounted thermal management with 6 cm² copper area.
Key Specifications

| VDS | 800 V - Withstands full mains-referenced DC link voltages up to 800 V in offline SMPS designs. |
| RDS(on), max | 1.2 Ω @ Tj=25°C - Enables low conduction loss in 4.5 A continuous drain applications. |
| Qg, typ | 11 nC - Reduces gate driver power requirement and enables efficient 100+ kHz switching. |
| VGS(th), typ | 3 V with ±0.5 V variation - Ensures consistent turn-on across temperature and production lot. |
| Eoss @ 500 V | 1.0 µJ - Low output energy reduces turn-off losses and improves light-load efficiency. |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1,2 | Power Source | Main current return path; carries full load current to ground plane. |
| 3 | Kelvin Source | Dedicated low-inductance sense node for gate driver reference; not interchangeable with Pins 1–2. |
| 4 | Gate | Control input; driven by isolated gate driver with recommended resistor placement at driver source. |
| 5–8 | Drain | High-voltage switch node; connected to primary winding and bulk capacitor in flyback topology. |
Key Features

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 |
|---|---|---|---|
| IPAK80R1K2P7 | Same die, DPAK-3L package; no Kelvin source; RDS(on) identical but higher source inductance. | Lacks Kelvin sensing; unsuitable for tightly regulated or paralleled designs requiring precise gate control. | Select when board space permits larger DPAK and Kelvin-source benefits are unnecessary. |
| IPP65R1K2CFD7 | 650V rating, TO-220FP package, 1.2 Ω RDS(on), no Kelvin source, CFD7 body diode. | Lower voltage rating limits use to 230 VAC-only designs; improved diode recovery but reduced safety margin. | Choose for cost-sensitive 650V systems where 800V margin is not required and TO-220 mounting is preferred. |

FAQ
What is the purpose of the Kelvin source pin (Pin 3) on IPLK80R1K2P7ATMA1?
Pin 3 is the Kelvin source terminal, providing a dedicated low-inductance connection for gate driver reference and current sensing. It must be routed separately from the main source pins (1 and 2) to avoid voltage drop errors in the gate loop. Interchanging it with Pins 1–2 causes unstable switching and potential device failure.
Can IPLK80R1K2P7ATMA1 be used in continuous conduction mode (CCM) flyback designs?
Yes-it supports CCM operation up to 4.5 A continuous drain current at 25°C case temperature. Derating is required above 25°C; at 100°C case, rated ID drops to 3.1 A. Its low Qg and optimized Coss make it suitable for high-frequency CCM designs with active clamp or QR control.
Does IPLK80R1K2P7ATMA1 require external gate resistors for paralleling?
Yes-when paralleling multiple units, Infineon recommends placing individual gate resistors at the driver source (not at the gate pin) to minimize loop inductance and ensure balanced turn-on. The internal gate resistance is 1.5 Ω, but external series resistance is needed for stability and current sharing.
Is the internal body diode suitable for synchronous rectification in secondary-side applications?
No-the internal body diode is optimized for freewheeling, not synchronous rectification. Its reverse recovery charge (Qrr = 4.4 µC) and time (trr = 750 ns) are higher than dedicated SR MOSFETs. For secondary-side synchronous rectification, use a dedicated low-VF, low-Qrr MOSFET instead.
