Product details

Overview

SPA11N60CFDXKSA1 from Infineon Technologies is a 600 V, 11 A CoolMOS™ CFD-series N-channel superjunction power MOSFET in TO-220-3-31 package, featuring 0.44 Ω max R_DS(on) at 10 V_GS, intrinsic fast-recovery body diode (t_rr = 140 ns), and 340 mJ single-pulse avalanche energy - deployed in industrial SMPS PFC stages and auxiliary power supplies.

For engineers reviewing the SPA11N60CFDXKSA1 datasheet, SPA11N60CFDXKSA1 pinout, SPA11N60CFDXKSA1 application, or SPA11N60CFDXKSA1 equivalent, key selection criteria include its 600 V V_DS, ultra-low Q_g (48–64 nC), 0.38 Ω typ R_DS(on) at 25 °C, 11 A continuous drain current, and JEDEC industrial-grade qualification.

Technical Context

This device implements Infineon's CoolMOS™ CFD technology with optimized charge balance for high-voltage switching efficiency. Its integrated fast-recovery body diode eliminates need for external antiparallel diodes in bridge-leg and LLC resonant topologies.

Designed for hard-switched and soft-switched converters, it supports high dv/dt (40 V/ns) and high di/dt (100 A/µs) operation while maintaining stable gate drive due to low Q_gd/Q_gs ratio (23/9 nC) and 7.5 V gate plateau voltage.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	600 V - supports 400 VAC input rectified systems with 50% safety margin
R_DS(on), max	0.44 Ω at T_j = 25 °C - enables <1.5 W conduction loss at 7 A DC
I_D, cont	11 A at T_C = 25 °C - rated for continuous operation in forced-air-cooled PFC boost inductors
Q_g	48–64 nC - reduces gate driver power demand and switching loss in 65–100 kHz designs
t_rr	140 ns - minimizes commutation loss and EMI in synchronous rectification and half-bridge configurations
E_AS	340 mJ - withstands single-event inductive energy spikes without failure in flyback snubbers
R_thJC	3.8 K/W - allows thermal design with standard TO-220 heatsinks up to 65 W dissipation

Pinout & Package

TO-220-3-31 package: isolated tab, vertical lead orientation, lead-free and RoHS-compliant. Thermal pad electrically connected to drain (Pin 2).

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Source)	Source terminal	Low-side reference node; connects to ground or current-sense resistor in buck/PFC topologies
Pin 2 (Drain)	Drain terminal	High-voltage switching node; electrically tied to metal tab for enhanced thermal transfer
Pin 3 (Gate)	Control input	High-impedance MOS gate requiring <10 V drive; sensitive to ringing due to low C_iss/C_oss ratio

Key Features

Feature	Design Value
Intrinsic fast-recovery body diode	Q_rr = 0.7 µC, t_rr = 140 ns - eliminates external diode in flyback clamp and active clamp circuits
Ultra-low gate charge	Q_g = 48–64 nC - reduces gate driver IC stress and enables use of low-power isolators (e.g., Si823x)
Periodic avalanche rated	E_AR = 340 mJ (single pulse), I_AR = 11 A - sustains repetitive inductive turn-off transients in motor drives
Extreme dv/dt rated	40 V/ns at T_j = 125 °C - prevents false turn-on in high-noise industrial environments

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
STP12N60DM6	600 V, 12 A, R_DS(on) = 0.38 Ω, Q_g = 52 nC, no integrated fast diode	Requires external ultrafast diode for hard-switched topologies	Prefer when cost sensitivity outweighs diode integration benefit
IPP60R190C7	600 V, 11 A, R_DS(on) = 0.19 Ω, Q_g = 54 nC, CFD7 generation with lower R_DS(on)	Better conduction efficiency but higher price and tighter layout constraints	Select for new designs targeting <0.5 W conduction loss at 10 A

Compared with STP12N60DM6 and IPP60R190C7, SPA11N60CFDXKSA1 uniquely balances integrated diode performance, industrial temperature rating, and proven field reliability in PFC and auxiliary SMPS - making it optimal for cost-constrained, high-volume industrial power supplies where diode integration simplifies BOM and layout.

FAQ

What is the maximum junction temperature for continuous operation?

The SPA11N60CFDXKSA1 has a maximum junction temperature of +150 °C per JEDEC industrial qualification. Continuous operation at this limit requires thermal design ensuring R_thJC ≤ 3.8 K/W and case temperature ≤ 100 °C under worst-case ambient and airflow conditions.

Is the body diode suitable for synchronous rectification?

No - although the intrinsic body diode has fast recovery (t_rr = 140 ns, Q_rr = 0.7 µC), it is not optimized for bidirectional conduction or low forward voltage in synchronous rectifier roles. It is designed for clamping and freewheeling, not replacement of Schottky or GaN-based SR FETs.

Does this MOSFET require a negative gate turn-off voltage?

No - the gate threshold voltage (V_GS(th)) ranges from 3 V to 5 V, and the device is fully specified for 0 V to +10 V gate drive. Negative turn-off voltage is unnecessary and not recommended; standard 0–10 V logic-level or isolated gate drivers suffice.

Can SPA11N60CFDXKSA1 replace older CoolMOS™ C3 parts in existing designs?

Yes - it is a direct drop-in replacement for SPA11N60C3 in most cases, offering improved R_DS(on) (0.44 Ω vs. 0.51 Ω), lower Q_g, and faster diode recovery. Layout and gate drive remain unchanged, but thermal margin improves by ~12% at 7 A continuous current.
