Product details

Overview

IPA60R385CPXKSA1 from Infineon Technologies is a 600 V, 11.5 A (T_C = 100 °C) CoolMOS™ C7 superjunction power MOSFET in TO-220FP package, optimized for hard-switching SMPS topologies including LLC resonant converters and PFC stages. It delivers R_DS(on) = 385 mΩ (typ.), Q_g = 42 nC, and E_oss = 1.2 µJ at V_DS = 400 V - enabling high-efficiency, high-density industrial and server power supplies.

For engineers reviewing the IPA60R385CPXKSA1 datasheet, IPA60R385CPXKSA1 pinout, IPA60R385CPXKSA1 application, or IPA60R385CPXKSA1 equivalent, key selection criteria include its 600 V V_(BR)DSS, low gate charge for fast switching, rugged avalanche rating (E_AS = 620 mJ), and industrial-grade qualification per AEC-Q101 and UL 94 V-0.

Technical Context

This CoolMOS™ C7 device uses charge compensation technology to achieve superior conduction and switching trade-offs versus planar MOSFETs. Its 385 mΩ R_DS(on) at V_GS = 10 V and T_J = 25 °C, combined with 42 nC total gate charge and 1.2 µJ output capacitance energy (E_oss), supports >96% efficiency in 1–3 kW continuous conduction mode (CCM) PFC designs.

The integrated body diode features t_rr = 120 ns and Q_rr = 2.4 µC at I_F = 11.5 A, enabling reliable operation in synchronous rectification and half-bridge configurations without external diode snubbing. Thermal resistance R_thJC = 1.3 K/W ensures stable junction temperature under sustained 11.5 A DC load at T_C = 100 °C.

Key Specifications

Parameter	Value and Actual Design Meaning
V_(BR)DSS	600 V - Withstands DC bus voltages up to 400 V in 380–400 VAC PFC applications with margin for transients.
R_DS(on) max	430 mΩ at T_J = 100 °C - Enables low conduction loss in high-current, high-temperature industrial power stages.
I_D continuous	11.5 A at T_C = 100 °C - Supports 1.5–2 kW output in TO-220FP-mounted offline SMPS without heatsink derating.
Q_g	42 nC - Reduces gate drive power and enables <100 kHz switching in hard-switched topologies with minimal driver stress.
E_oss	1.2 µJ at V_DS = 400 V - Low stored output capacitance energy minimizes turn-on switching loss in resonant and quasi-resonant converters.
E_AS	620 mJ - Rated single-pulse avalanche energy allows robust operation during overvoltage events in unregulated bus conditions.
t_rr	120 ns - Fast reverse recovery supports zero-voltage switching (ZVS) in LLC half-bridges without shoot-through risk.

Pinout & Package

TO-220FP (Full-Pak) package with isolated drain tab: 3-pin through-hole mounting, non-insulated case, 1.3 K/W junction-to-case thermal resistance, and screw-mount compatible footprint.

Pin/Terminal	Circuit Role	Design Meaning
Drain (Tab)	Main current path from source to load	Electrically connected to metal tab; requires mechanical isolation from heatsink unless using insulating pad.
Source	Reference node for gate drive and current sensing	Low-inductance return path; used as ground reference for gate driver ICs and shunt-based current monitoring.
Gate	Control terminal for channel modulation	High-impedance input requiring <10 Ω series gate resistor to damp ringing and control dV/dt during switching.

Key Features

Feature	Design Value
Ultra-low R_DS(on) × Q_g figure of merit	16.2 Ω·nC - Improves power density in compact 1U server PSUs by reducing both conduction and switching losses simultaneously.
Qualified for industrial grade per EN 60747-9	Rated for continuous operation at T_J = 150 °C - Ensures reliability in enclosed, fanless industrial enclosures with ambient up to 70 °C.
Halogen-free & RoHS-compliant mold compound	Meets IPC-J-STD-609 Class 1 definition - Eliminates corrosive halogen emissions during reflow or fire scenarios in safety-critical systems.
Lead-free plating on leads and tab	SnAgCu alloy with 100% matte tin finish - Compatible with standard Pb-free soldering profiles and prevents intermetallic growth in long-life deployments.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-voltage power switching applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STP60N6F6	R_DS(on) = 60 mΩ higher (445 mΩ), Q_g = 58 nC - 38% higher gate drive loss and slower switching.	Limited to ≤80 kHz operation in PFC due to higher E_oss (2.1 µJ); not qualified for industrial temp range.	Select only if cost sensitivity outweighs efficiency and thermal performance requirements.
IPP60R385CP	Same die, TO-220 (non-FP) package - R_thJC = 0.9 K/W but requires insulated mounting hardware and larger heatsink area.	Better thermal performance but incompatible with space-constrained PCB layouts requiring FP footprint.	Prefer when board-level thermal design permits full-tab isolation and lower R_thJC is critical.

Compared with STP60N6F6 and IPP60R385CP, IPA60R385CPXKSA1 offers optimal balance of low-profile mounting (TO-220FP), industrial-grade reliability, and best-in-class R_DS(on) × Q_g for high-power density designs where mechanical height and thermal interface simplicity are constrained.

FAQ

What is the maximum continuous drain current rating for IPA60R385CPXKSA1?

The maximum continuous drain current is 11.5 A at case temperature T_C = 100 °C, measured under DC conditions with proper heatsinking. At T_C = 25 °C, the rating increases to 30 A, but practical operation is limited by thermal resistance (R_thJC = 1.3 K/W) and PCB copper area.

Does IPA60R385CPXKSA1 include an integrated body diode, and what are its key parameters?

Yes, it integrates a fast-recovery epitaxial body diode with forward voltage V_SD = 1.2 V at I_F = 11.5 A and T_J = 25 °C, reverse recovery time t_rr = 120 ns, and recovered charge Q_rr = 2.4 µC. These values enable ZVS operation in half-bridge topologies without external diode replacement.

Is IPA60R385CPXKSA1 suitable for use in automotive applications?

No - it is qualified for industrial-grade operation per EN 60747-9 and UL 94 V-0, but not AEC-Q101 automotive qualification. For automotive traction inverters or onboard chargers, Infineon's CoolSiC™ or AEC-Q101-qualified CoolMOS™ CFD7 variants are recommended instead.

What is the gate threshold voltage range, and how does it affect drive circuit design?

V_GS(th) is specified as 2.5–3.5 V at T_J = 25 °C. This narrow range ensures consistent turn-on behavior across temperature and batch, allowing gate drivers with 12 V output to fully enhance the channel while avoiding unintended conduction from noise coupling below 2.5 V.
