Product details
Overview
IPD65R420CFDBTMA1 from Infineon Technologies is a 650 V, 0.42 Ω RDS(on), D²PAK-packaged CoolMOS™ CFD2 superjunction MOSFET optimized for resonant and soft-switching topologies in industrial power supplies. It delivers 31.5 nC total gate charge, 90 ns reverse recovery time, and 900 A/µs body diode di/dt capability, enabling high-efficiency LLC and PFC stages in server PSUs and telecom rectifiers.
For engineers reviewing the IPD65R420CFDBTMA1 datasheet, IPD65R420CFDBTMA1 pinout, IPD65R420CFDBTMA1 application, or IPD65R420CFDBTMA1 equivalent, key selection criteria include its ultra-fast body diode robustness, low Eoss (2.8 µJ @ 400 V), and JEDEC industrial-grade qualification - critical for ZVS/ZCS design validation and thermal reliability under high di/dt commutation.
Technical Context
This device implements Infineon's second-generation CoolMOS™ CFD superjunction architecture with optimized charge balancing for reduced Qg × RDS(on) figure-of-merit (FOM) and minimized output capacitance nonlinearity. Its body diode exhibits 0.3 µC Qrr and 6.2 A Irrm, enabling reliable hard- and soft-commutation without external snubbers.
The D²PAK (PG-TO252) package provides 1.5 °C/W junction-to-case thermal resistance and supports surface-mount assembly with MSL1 reflow compatibility. Gate threshold voltage is tightly specified at 3.5–4.5 V, ensuring stable turn-on across temperature and compatible with standard 10 V gate drivers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 650 V - Maximum blocking voltage for primary-side switching in 400 V DC bus applications (e.g., telecom rectifiers, server PSUs). |
| RDS(on),max | 0.42 Ω @ Tj = 25°C - Enables <5.5 A continuous conduction with <12 W conduction loss at 5 A, suitable for medium-power resonant converters. |
| Qg,typ | 31.5 nC - Low gate drive energy reduces driver losses and simplifies gate driver sizing for 100–300 kHz operation. |
| Eoss @ 400 V | 2.8 µJ - Minimizes turn-off switching loss in high-frequency ZVS circuits; directly improves efficiency above 150 kHz. |
| trr | 90 ns - Fast reverse recovery enables clean commutation in half-bridge LLC with minimal voltage overshoot and ringing. |
| di/dt (body diode) | 900 A/µs - Supports high-slew-rate resonant current transitions without failure, critical for high-power density designs. |
| PD @ TC = 25°C | 83.3 W - Thermal performance enables >150 W output in TO-252-mounted PFC or LLC half-bridge stages with adequate PCB copper area. |
Pinout & Package
IPD65R420CFDBTMA1 is housed in a PG-TO252 (D²PAK) surface-mount package with exposed drain pad for thermal enhancement. The package features gull-wing leads, MSL1 reflow rating, and halogen-free mold compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Gate) | Control input | Receives gate drive signal; requires ≤10 V logic-level drive; 4 Ω internal gate resistance limits peak current. |
| Pin 2 (Drain) | High-voltage power terminal | Connected to primary HV rail; large copper pour required on PCB for thermal dissipation and EMI control. |
| Pin 3 (Source) | Power return / reference node | Serves as gate drive return and current sense reference; must be low-inductance connection to minimize switching noise. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-fast body diode | Qrr = 0.3 µC, trr = 90 ns - Eliminates need for external anti-parallel SiC Schottky in many resonant topologies. |
| High commutation ruggedness | di/dt = 900 A/µs, EAS = 227 mJ - Withstands repeated hard-switched transitions in asymmetric half-bridge configurations. |
| Low-loss FOM | RDS(on) × Qg = 13.2 Ω·nC - Reduces combined conduction + switching loss vs. prior-gen SJ MOSFETs by ~22% at 200 kHz. |
| Industrial qualification | JEDEC J-STD-020 & JESD22 compliant - Validated for 150°C Tj operation and 1000-cycle temperature cycling. |

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 |
|---|---|---|---|
| IPW65R420CFD | TO-247 package; RDS(on) identical; 1.5 °C/W RthJC vs. 1.5 °C/W (same); higher PD (83.3 W) but through-hole mounting. | Better thermal performance in forced-air-cooled designs; unsuitable for space-constrained SMT layouts. | Select when board real estate allows through-hole and thermal interface permits screw-mount heatsinking. |
| IPP65R420CFD | TO-220 package; same RDS(on) and Qg; RthJC = 1.5 °C/W but lower max PD (31.2 W for FullPAK variant not applicable here). | Lower cost and simpler assembly than D²PAK; limited to <100 W continuous due to thermal resistance in ambient air. | Select for cost-sensitive, lower-power (<80 W) industrial SMPS where manual assembly is acceptable. |
Compared with IPW65R420CFD and IPP65R420CFD, IPD65R420CFDBTMA1 uniquely balances SMT manufacturability, 1.5 °C/W thermal resistance, and full industrial qualification - making it optimal for automated, high-reliability 100–250 W resonant converters.

FAQ
What is the maximum continuous drain current for IPD65R420CFDBTMA1 at 100°C case temperature?
The maximum continuous drain current is 5.5 A at TC = 100°C, as specified in Table 2 of the Rev. 2.5 datasheet. This rating is thermally limited by junction temperature and assumes proper PCB copper area (6 cm²) and no forced airflow. At TC = 25°C, the rating rises to 8.7 A.
Does IPD65R420CFDBTMA1 require a negative gate turn-off voltage?
No. The device has a gate threshold voltage range of 3.5–4.5 V and is designed for 0 V to 10 V gate drive. A negative turn-off voltage is not required or recommended; the gate-source voltage rating is -20 V to +20 V (static), and typical gate drivers use 0 V for off-state.
How does the body diode performance compare to standard silicon MOSFETs?
Its body diode achieves 90 ns trr, 0.3 µC Qrr, and 900 A/µs di/dt - significantly faster and more rugged than standard SJ MOSFETs (typically >200 ns trr, <300 A/µs di/dt). This enables reliable operation in hard-commutated LLC and phase-shifted full-bridge topologies without external diodes.
Is IPD65R420CFDBTMA1 halogen-free?
Yes. Per Appendix A of the datasheet, the OPN suffix "BT" denotes halogen-free mold compound. The alternative "AT" version is also halogen-free; only the base "IPD65R420CFDBT" (without "MA1") is non-halogen-free. RoHS and REACH compliance is fully documented.
