Product details
Overview
IPA60R145CFD7XKSA1 from Infineon is a 600 V, 145 mΩ superjunction MOSFET with integrated ultrafast body diode, designed for primary-side switching in resonant LLC and ZVS phase-shift full-bridge topologies. It delivers Qrr = 190 nC (typ), trr = 105 ns (max), RDS(on) max = 145 mΩ at VGS = 10 V, and Qg = 42 nC (typ), enabling high-efficiency operation in server power supplies and EV charging stations.
For engineers reviewing the IPA60R145CFD7XKSA1 datasheet, IPA60R145CFD7XKSA1 pinout, IPA60R145CFD7XKSA1 application, or IPA60R145CFD7XKSA1 equivalent, key selection criteria include reverse recovery charge (Qrr), gate charge (Qg), RDS(on)/package optimization, and hard commutation ruggedness in soft-switching SMPS designs.
Technical Context
The IPA60R145CFD7XKSA1 implements CoolMOS™ CFD7 technology - a 600 V superjunction MOSFET architecture featuring a monolithically integrated fast-recovery body diode. Its optimized charge distribution reduces Qg by ~15% and Qrr by up to 69% versus prior CFD2 generation and leading competitors.
This device supports zero-voltage switching (ZVS) and zero-current switching (ZCS) operation via low trr (105 ns max) and high dv/dt (80 V/ns) and di/dt (100 A/µs) ruggedness. It is rated for continuous ID = 21 A (Tc = 100 °C) and pulsed ID = 72 A, with SOA compliance up to 100 µs at 400 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 600 V - rated blocking voltage for primary-side switch in 400 V DC bus telecom/server SMPS |
| RDS(on) max | 145 mΩ at VGS = 10 V, Tj = 25 °C - enables compact heatsinking in 2–3 kW resonant converters |
| Qrr | 190 nC (typ) - reduces diode conduction loss and EMI in LLC half-bridge freewheeling |
| trr | 105 ns (max) - lowest published trr in 600 V SJ MOSFET class, critical for ZVS timing margin |
| Qg | 42 nC (typ) - lowers gate drive loss and allows use of cost-optimized 2EDN EiceDRIVER™ ICs |
| ID (cont) | 21 A at Tc = 100 °C - supports 2.5 kW output with TO-220 FullPAK thermal resistance of 0.9 K/W |

Pinout & Package
IPA60R145CFD7XKSA1 is housed in TO-220 FullPAK package (3-pin, isolated tab), with drain connected to the metal tab for direct heatsink mounting and optimal thermal performance in high-power SMPS.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Source) | Power source terminal for channel current return path | Low-inductance connection point for Kelvin source routing in high-di/dt applications |
| Pin 2 (Gate) | Control input for MOSFET channel turn-on/off | Requires <10 Ω series gate resistor to damp ringing during fast dV/dt transitions |
| Pin 3 (Drain) | Main high-voltage power terminal (connected to tab) | Tab is electrically tied to drain - requires insulated mounting hardware for PCB isolation |
Key Features
| Feature | Design Value |
|---|---|
| Ultrafast body diode | Qrr = 190 nC (typ), trr = 105 ns (max) - eliminates need for external SiC/Schottky anti-parallel diode in LLC |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage resonant switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IPP60R145CFD7 | Same die, TO-220 (non-isolated tab) package - RthJC = 0.85 K/W, no electrical isolation | Suitable only when drain is referenced to chassis ground; not usable in floating high-side configurations | Select IPP60R145CFD7 only if mechanical mounting allows direct drain-to-heatsink contact without insulation. |
| IPW60R145CFD7 | Same die, TO-247 package - RthJC = 0.45 K/W, higher current rating (ID = 25 A), larger footprint | Preferred for >3 kW designs requiring lower thermal resistance and higher surge current capability | Choose IPW60R145CFD7 when thermal budget is tight and board space permits larger through-hole mounting. |
Compared with IPP60R145CFD7 and IPW60R145CFD7, IPA60R145CFD7XKSA1 uniquely combines electrical isolation (FullPAK), industry-leading Qrr/trr, and TO-220 form factor - making it optimal for space-constrained, safety-isolated 2–3 kW server and telecom SMPS where creepage/clearance and thermal management are co-constrained.

FAQ
What is the maximum recommended gate resistor value for IPA60R145CFD7XKSA1 in a 250 kHz LLC design?
A 6.8 Ω non-inductive gate resistor is recommended to balance switching speed and EMI in 250 kHz LLC operation. This value limits peak gate current to <2 A while maintaining <35 ns turn-off delay, preserving ZVS margin across 10–100% load range per Infineon AN2019-09.
Does IPA60R145CFD7XKSA1 require a negative gate turn-off voltage?
No - the device operates reliably with 0 V to –5 V turn-off bias. Its enhanced dv/dt immunity (80 V/ns) and low Miller charge eliminate need for active negative gate drive, simplifying gate driver design versus older SJ MOSFETs.
Can IPA60R145CFD7XKSA1 replace IPA60R170CFD7 in an existing design?
Yes - it is a direct drop-in replacement with identical pinout, package, and thermal footprint. The lower RDS(on) (145 vs. 170 mΩ) reduces conduction loss by ~15%, but gate drive energy increases slightly (Qg = 42 vs. 37 nC); verify gate driver peak current capability.
Is the drain tab of IPA60R145CFD7XKSA1 electrically isolated from the PCB mount surface?
Yes - the TO-220 FullPAK construction features an electrically isolated metal tab. The drain is internally connected to the tab, but the tab's underside is coated with insulating material, allowing direct mounting to grounded heatsinks without additional isolation hardware.
