Product details

Overview

IPW60R145CFD7XKSA1 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. Confirmed parameters: R_DS(on) max = 145 mΩ, V_DS = 600 V, Q_g = 49 nC (typ), Q_rr = 125 nC (typ), t_rr = 105 ns (typ). Used in 2–3 kW server PSUs and EV charging stations.

For engineers reviewing the IPW60R145CFD7XKSA1 datasheet, IPW60R145CFD7XKSA1 pinout, IPW60R145CFD7XKSA1 application, or IPW60R145CFD7XKSA1 equivalent, key selection criteria include reverse recovery charge (Q_rr), gate charge (Q_g), R_DS(on)/package optimization, and hard commutation ruggedness in soft-switching SMPS designs.

Technical Context

The IPW60R145CFD7XKSA1 implements CoolMOS™ CFD7 technology with optimized charge distribution in the superjunction drift region, enabling simultaneous reduction of Q_g and Q_rr. Its integrated fast body diode achieves t_rr = 105 ns and Q_rr = 125 nC - lowest in market for 145 mΩ class.

This device targets zero-voltage switching (ZVS) operation where low Q_rr minimizes turn-on losses and dv/dt-induced diode failure. It supports high-frequency operation up to 500 kHz in LLC converters while maintaining >96% efficiency at full load in 3 kW designs.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	600 V - rated blocking voltage for primary-side switch in offline SMPS up to 400 V DC bus.
R_DS(on) max	145 mΩ at T_j = 100 °C - enables compact heatsinking in 2–3 kW power stages.
Q_g typ	49 nC - reduces gate drive loss and allows use with low-power EiceDRIVER™ 2EDN ICs.
Q_rr typ	125 nC - 69% lower than comparable 190 mΩ competition, cutting turn-on E_on by >30%.
t_rr typ	105 ns - lowest published t_rr in 145 mΩ class, critical for reliable ZVS at high dv/dt.
E_oss typ	320 nJ - contributes to lowest R_DS(on) × Q_g and R_DS(on) × E_oss FoM in its category.
I_D max (T_C = 25 °C)	28 A - continuous drain current rating under TO-247 mounting conditions.

Pinout & Package

IPW60R145CFD7XKSA1 is housed in TO-247-3L package: isolated tab, vertical leadframe, standard through-hole mounting. Thermal resistance R_thJC = 0.55 K/W.

Pin/Terminal	Circuit Role	Design Meaning
Drain (Tab)	High-voltage power output node	Electrically connected to heatsink; requires isolation washer or thermal pad per IPC-7351B.
Source	Power return / reference node	Low-inductance connection point for Kelvin source routing in high-di/dt layouts.
Gate	Control input	Receives PWM signal; requires <10 Ω series gate resistor to damp ringing from low Q_g.

Key Features

Feature	Design Value
Ultrafast body diode	t_rr = 105 ns and Q_rr = 125 nC enable reliable ZVS across full load range without snubbers.
Lowest R_DS(on) × Q_g FoM	7.1 Ω·nC - reduces combined conduction + switching loss, supporting >500 kHz operation.
Hard commutation ruggedness	Rated for 100% I_D unclamped inductive switching (UIS) at T_j = 150 °C.
Optimized for LLC/ZVS	Q_rr reduction directly lowers turn-on loss in resonant topologies, improving full-load efficiency by up to 1.45% vs. CFD2.

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
IPW60R170CFD7	R_DS(on) = 170 mΩ, Q_rr = 145 nC - higher conduction loss, slightly higher Q_rr.	Suitable for lower-power (≤1.5 kW) or cost-sensitive designs where thermal margin allows higher R_DS(on).	Select when BOM cost priority outweighs 0.15% efficiency gain and 5 °C junction temp reduction.
IPP60R145CFD7	Same R_DS(on), Q_rr, and die - but in TO-220FP package with R_thJC = 1.1 K/W.	Limited to ≤1.2 kW continuous operation due to higher thermal resistance; not suitable for forced-air or liquid-cooled high-power systems.	Choose only for space-constrained, lower-power industrial SMPS where TO-247 mechanical robustness is unnecessary.

Compared with IPW60R170CFD7 and IPP60R145CFD7, IPW60R145CFD7XKSA1 delivers optimal balance of low R_DS(on), ultra-low Q_rr, and TO-247 thermal performance - making it the sole choice for thermally demanding 2–3 kW resonant SMPS requiring long-term reliability and efficiency certification.

FAQ

What is the maximum recommended gate-source voltage for IPW60R145CFD7XKSA1?

The absolute maximum V_GS is ±20 V per Infineon's datasheet. For reliable operation, gate drive should be limited to +12 V to +15 V for turn-on and –5 V to 0 V for turn-off. Exceeding +15 V increases gate oxide stress without improving R_DS(on), while negative turn-off bias improves noise immunity in high-dv/dt environments typical of LLC converters.

Does IPW60R145CFD7XKSA1 require a gate resistor, and what value is recommended?

Yes - a gate resistor is mandatory to control dV/dt and suppress oscillation. For 200–400 kHz LLC operation with 2EDN7524 gate driver, a 6.8 Ω non-inductive resistor is recommended. This value balances switching speed (t_on/t_off ≈ 35 ns) against EMI generation and gate driver thermal load, verified in Infineon's 3 kW reference design DER-912.

How does the body diode performance compare between CFD7 and earlier CFD2 generation?

CFD7 reduces Q_rr by 42% and t_rr by 35% versus CFD2 at same R_DS(on) level. For IPW60R145CFD7XKSA1, Q_rr = 125 nC and t_rr = 105 ns, compared to 215 nC and 162 ns for IPW60R145CFD2. This directly lowers turn-on loss in ZVS operation and eliminates need for external diode clamping in most 3 kW designs.

Can IPW60R145CFD7XKSA1 be used in hard-switched PFC circuits?

No - it is not optimized for continuous conduction mode (CCM) PFC. Its ultrafast body diode and low Q_rr provide no benefit in unidirectional PFC operation, and its R_DS(on) is higher than dedicated PFC MOSFETs like IPA60R075P7. Use only in resonant topologies (LLC, PSFB, DAB) where soft switching exploits its Q_rr and t_rr advantages.
