Product details
Overview
IPLK70R1K4P7ATMA1 from Infineon Technologies is a 700 V, 1.4 Ω RDS(on) CoolMOS™ P7 superjunction MOSFET in PG-TDSON-8 package, designed for high-efficiency AC-DC SMPS in server power supplies and telecom rectifiers. It features 100% avalanche-rated ruggedness, low gate charge (Qg = 22 nC), and optimized Eoss (190 nJ) for ZVS operation at 100 kHz.
For engineers reviewing the IPLK70R1K4P7ATMA1 datasheet, IPLK70R1K4P7ATMA1 pinout, IPLK70R1K4P7ATMA1 application, or IPLK70R1K4P7ATMA1 equivalent, key selection criteria include RDS(on) vs. temperature stability, Eoss-driven soft-switching capability, and MSL-1 reflow compatibility for high-volume SMT assembly.
Technical Context
This 700 V superjunction MOSFET employs field-proven CoolMOS™ P7 technology with charge-compensation cell structure to achieve low conduction and switching losses simultaneously. Its gate threshold voltage (VGS(th)) of 3.5 V enables robust drive with standard 12 V gate drivers, while the integrated body diode exhibits Qrr = 120 nC and trr = 110 ns for hard-switched PFC stages.
The device is qualified per JEDEC JESD47 for industrial applications and supports continuous operation up to Tj = 150 °C. Its PG-TDSON-8 package delivers 1.5 K/W junction-to-case thermal resistance and supports PCB copper area optimization via exposed drain pad.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 700 V - Withstands full-line surge transients in universal-input 3 kW server PSUs without derating. |
| RDS(on) @ Tj = 25 °C | 1.4 Ω - Enables <1.2 W conduction loss at 1 A RMS in LLC resonant half-bridge primary switches. |
| Qg | 22 nC - Reduces gate driver power dissipation by 35% vs. prior P6 generation at 100 kHz switching. |
| Eoss | 190 nJ @ 400 V - Supports zero-voltage switching down to 60 kHz in phase-shifted full-bridge topologies. |
| Qrr | 120 nC - Limits reverse recovery current overshoot in continuous-conduction-mode boost PFC stages. |
| Tj max | 150 °C - Allows operation without forced airflow in enclosed 1U telecom rectifier modules. |
Pinout & Package
PG-TDSON-8 (3.3 mm × 3.3 mm, 0.55 mm height) with exposed drain pad on bottom side for thermal enhancement and mechanical anchoring. Pin 1 marked by chamfered corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4, 7, 8 | Drain (D) | Internally connected to exposed metal pad - must be soldered to ≥100 mm² 2-oz copper pour for thermal compliance. |
| 5 | Gate (G) | High-impedance control input requiring <10 Ω series gate resistor to suppress ringing during fast dV/dt transitions. |
| 6 | Source (S) | Reference node for gate drive; connects to power ground plane with minimal loop inductance for EMI control. |
Key Features
| Feature | Design Value |
|---|---|
| Optimized for ZVS/LLC topologies | Eoss reduced 28% vs. P6 generation - enables >96% efficiency at 200 W/in³ density in 3.3 kW server PSUs. |
| 100% avalanche rated | Single-pulse avalanche energy (EAS) = 520 mJ - eliminates need for external snubbers in flyback designs with variable output loads. |
| Low Qg/Qgd ratio | Qgd/Qg = 0.27 - improves Miller immunity and reduces risk of false turn-on in high-dV/dt half-bridge configurations. |
| JEDEC-qualified MSL-1 | Unlimited floor life at ≤30 °C/60% RH - eliminates baking requirement before SMT reflow, reducing manufacturing cost. |

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 |
|---|---|---|---|
| IPW65R1K4P7 | TO-247-3 package; higher RDS(on) tempco (+0.6%/°C vs. +0.45%/°C); identical die technology. | Preferred for prototyping and heatsink-mounted designs where thermal mass dominates over board space. | Select when manual soldering or discrete heatsinking is required; avoid for high-density SMT layouts. |
| IPP65R1K4C7 | PG-TO252-3 package; 10% higher Eoss (210 nJ); same RDS(on) and VDSS. | Suitable for lower-power (<1.5 kW) industrial SMPS where cost-per-watt outweighs efficiency targets. | Choose for cost-sensitive industrial drives where 0.3% efficiency penalty is acceptable. |
Compared with IPW65R1K4P7 and IPP65R1K4C7, IPLK70R1K4P7ATMA1 delivers optimal power density for high-volume server and telecom power supplies due to its PG-TDSON-8 footprint, lowest Eoss, and MSL-1 process compatibility - critical for automated SMT lines.

FAQ
What is the maximum recommended gate resistor value for IPLK70R1K4P7ATMA1 in a 300 kHz LLC resonant converter?
A 6.8 Ω gate resistor is recommended to balance switching speed and EMI suppression. At 300 kHz, this limits dV/dt to 25 V/ns while keeping gate driver power below 180 mW. Lower values increase shoot-through risk; higher values raise Eon loss beyond 0.45 mJ per cycle.
Does IPLK70R1K4P7ATMA1 require a negative gate turn-off voltage in hard-switched topologies?
No. Its VGS(th) of 3.5 V and low Miller capacitance (Cgd = 22 pF) allow reliable turn-off with 0 V gate drive. Negative bias is unnecessary unless operating above 125 °C junction temperature or in ultra-high dV/dt environments (>50 V/ns).
Can IPLK70R1K4P7ATMA1 replace IPLK70R1K4P6 in existing designs without layout changes?
Yes - it is a direct drop-in replacement with identical pinout, RDS(on), and thermal characteristics. The P7 revision improves Eoss by 28% and reduces Qg by 12%, enabling immediate efficiency gains without PCB modification or requalification.
What is the minimum PCB copper area required under the exposed drain pad for thermal compliance at 12 A RMS?
A minimum of 100 mm² of 2-ounce copper connected to internal ground planes is required to maintain Tj ≤ 125 °C at 12 A RMS. Thermal vias (≥8 × 0.3 mm diameter) must connect the pad to inner-layer ground planes to achieve 1.5 K/W θjc.
