Product details
Overview
IPB65R155CFD7ATMA1 from Infineon is a 650 V superjunction MOSFET in D²PAK (PG-TO263-3) package, featuring 155 mΩ max RDS(on), ultra-fast body diode (diF/dt = 1300 A/µs), and optimized for zero-voltage switching topologies. It delivers high efficiency in industrial SMPS, server power supplies, telecom rectifiers, and EV charging systems.
For engineers reviewing the IPB65R155CFD7ATMA1 datasheet, IPB65R155CFD7ATMA1 pinout, IPB65R155CFD7ATMA1 application, or IPB65R155CFD7ATMA1 equivalent, key selection criteria include hard commutation ruggedness, low Eoss (4.0 µJ @ 400 V), temperature-stable RDS(on), gate charge profile (Qg = 28 nC), and thermal resistance (RthJC = 1.62 °C/W).
Technical Context
This CoolMOS™ CFD7 device employs charge compensation technology with integrated fast-recovery body diode and ESD protection. Its optimized cell layout reduces switching losses while maintaining robust avalanche capability (EAS = 64 mJ) and high dv/dt immunity (120 V/ns).
The MOSFET supports resonant soft-switching operation via precise control of Qgd/Qgs ratio (8 nC / 7 nC) and low Co(er) (50 pF), enabling stable phase-shift full-bridge and LLC converter designs at bus voltages up to 400 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS max | 650 V - Withstands DC bus voltages up to 400 V in ZVS topologies with safety margin |
| RDS(on) max | 155 mΩ @ Tj = 25°C - Enables low conduction loss in high-current primary-side switches |
| Qg typ | 28 nC - Supports efficient gate driving with moderate drive strength requirements |
| Eoss | 4.0 µJ @ 400 V - Reduces turn-on switching loss in resonant converters |
| diF/dt | 1300 A/µs - Ensures reliable hard commutation without oscillation or failure |
| RthJC | 1.62 °C/W - Allows high power dissipation (77 W @ TC = 25°C) with minimal junction-to-case thermal drop |
| ID,pulse | 55 A - Supports peak current handling during transient overload conditions |
Pinout & Package
Package: PG-TO263-3 (D²PAK), surface-mount with exposed drain tab for thermal enhancement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Gate) | Control terminal | Receives PWM signal; requires gate resistor (RG ≈ 10 Ω typical) to damp ringing |
| Pin 2 (Drain) + Tab | High-side power path | Electrically connected to internal drain; tab provides primary thermal path to PCB copper |
| Pin 3 (Source) | Reference node | Serves as return path for gate drive and load current; critical for stable switching waveform integrity |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-fast body diode | 1300 A/µs commutation speed enables reliable hard-switched transitions without snubbers |
| Low RDS(on) temp coefficient | RDS(on) increases only ~1.8× from 25°C to 150°C - improves current sharing in paralleled configurations |
| Reduced Eoss | 4.0 µJ @ 400 V - cuts turn-on loss by >35% vs. prior CFD2 generation in LLC operation |
| Integrated ESD protection | HBM rating ≥2 kV - eliminates need for external ESD clamps in board-level assembly |
| Avalanche-rated | Single-pulse EAS = 64 mJ - withstands unclamped inductive switching events in industrial environments |

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 |
|---|---|---|---|
| IPW65R155CFD7XKSA1 | TO-247-3 package; identical die, higher RthJC (0.55 °C/W) but larger copper area for cooling | Better suited for forced-air-cooled industrial UPS where mechanical mounting flexibility is required | Select when thermal interface constraints prevent D²PAK soldering or when higher pulse current derating is needed |
| STP65N155F7 | 155 mΩ RDS(on), 650 V, but slower body diode (diF/dt = 600 A/µs); no integrated ESD diode | Limited to soft-switched applications without hard commutation stress (e.g., fixed-frequency flyback) | Choose only if cost sensitivity outweighs ruggedness requirements and external ESD protection is acceptable |
Compared with IPW65R155CFD7XKSA1 and STP65N155F7, the IPB65R155CFD7ATMA1 offers superior thermal performance in space-constrained SMD layouts and unmatched hard commutation robustness-critical for phase-shift full-bridge and bidirectional EV charger designs where reliability under transient fault conditions is non-negotiable.

FAQ
What is the maximum continuous drain current at 100°C case temperature?
The maximum continuous drain current is 10 A at TC = 100°C, as specified in Table 2 of the Rev. 2.0 datasheet. This rating accounts for thermal derating due to junction-to-case resistance (1.62 °C/W) and safe operating area limits under DC conditions.
Does this MOSFET require an external gate resistor for stability?
Yes - a gate resistor of 10.2 Ω is used in the official switching time test circuit (Table 9). Typical design practice uses 10–22 Ω to suppress gate oscillation and control dV/dt, especially when paralleling multiple devices or driving from low-impedance controllers.
Can IPB65R155CFD7ATMA1 be used in parallel configurations?
Yes - its positive RDS(on) temperature coefficient and matched threshold voltage (VGS(th) = 3.5–4.5 V) support current sharing. Infineon recommends ferrite beads on each gate line or individual totem-pole drivers to ensure balanced turn-on and prevent oscillatory current imbalance.
Is the drain tab electrically isolated from the PCB mounting pad?
No - the drain tab is internally connected to Pin 2 (Drain) and must be soldered directly to a large copper pour serving as both thermal sink and high-current return path. Electrical isolation requires insulated mounting hardware or thermal interface materials with dielectric properties.
