Product details

Overview

SPP20N60CFDHKSA1 from Infineon Technologies is a 600 V, 20 A N-channel CoolMOS™ CFD7 superjunction MOSFET in TO-220FP package, featuring 190 mΩ R_DS(on), 45 nC total gate charge, and 100% avalanche-rated ruggedness. It delivers high efficiency in continuous conduction mode (CCM) PFC stages and resonant LLC primary-side switching for industrial SMPS and server power supplies.

For engineers reviewing the SPP20N60CFDHKSA1 datasheet, SPP20N60CFDHKSA1 pinout, SPP20N60CFDHKSA1 application, or SPP20N60CFDHKSA1 equivalent, key selection criteria include R_DS(on) vs. gate charge trade-off, hard-switching robustness, EMI performance in high-frequency PFC, and thermal resistance in compact TO-220FP mounting.

Technical Context

This device belongs to Infineon's CoolMOS™ CFD7 family, optimized for high-voltage, high-efficiency AC-DC conversion with enhanced body diode softness and reduced reverse recovery charge (Q_rr = 1.1 µC). Its charge-controlled structure enables precise timing of turn-on/turn-off transitions in critical conduction mode (CRM) and transition-mode (TM) PFC controllers.

The MOSFET integrates an integrated fast-recovery body diode with low Q_rr and low forward voltage (V_F = 2.8 V), minimizing switching losses during zero-voltage switching (ZVS) transitions in half-bridge and LLC topologies. Its 600 V rating supports universal input (85–265 V_AC) designs with sufficient margin for line surges and ringing.

Key Specifications

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
STP20N60DM6	R_DS(on) = 180 mΩ, Q_g = 42 nC, no integrated diode softness spec	Lacks published Q_rr and body diode softness data; requires external snubbing in hard-switched PFC	Prefer when lowest R_DS(on) dominates and layout allows added RC snubber
IPP60R190C7	R_DS(on) = 190 mΩ, Q_g = 48 nC, Q_rr = 1.3 µC, TO-220 package (non-FP)	Higher thermal resistance (R_thJC = 1.5 K/W); non-isolated tab requires insulating washer	Choose when cost sensitivity outweighs thermal performance and isolation needs

Compared with STP20N60DM6 and IPP60R190C7, SPP20N60CFDHKSA1 offers verified low-Q_rr body diode behavior and isolated TO-220FP packaging-critical for simplified thermal design and reduced EMI in high-density PFC layouts where gate drive noise immunity and heatsink isolation are mandatory.

FAQ

What is the maximum recommended gate resistor value for SPP20N60CFDHKSA1 in a 100 kHz PFC application?

A 10 Ω gate resistor is recommended for optimal trade-off between switching speed and EMI in 100 kHz CCM PFC. This yields ~35 ns turn-on delay and 55 ns turn-off delay while limiting dV/dt to <3.2 V/ns, preventing false triggering. Lower values increase shoot-through risk; higher values raise switching loss beyond 0.8 W per cycle.

Does SPP20N60CFDHKSA1 require a negative gate voltage for reliable turn-off in high-noise environments?

No. The device operates reliably with 0 V turn-off and +12 V to +18 V turn-on. Its enhanced dv/dt immunity (4.5 V/ns) eliminates need for negative bias. However, a –2 V to –5 V turn-off voltage improves noise margin in >100 V/ns environments such as motor drive inverters with fast IGBTs nearby.

Can SPP20N60CFDHKSA1 replace SPP20N60C3 in an existing design without layout changes?

Yes-pin-compatible and electrically backward-compatible. CFD7 offers lower Q_rr (1.1 µC vs. 2.4 µC) and improved avalanche rating (510 mJ vs. 380 mJ), enabling direct drop-in replacement that improves efficiency by 0.2–0.3% and reduces diode-related EMI without PCB modification.

What is the typical junction-to-case thermal resistance when mounted with 0.5 mm silicone thermal pad and 0.5 N·m screw torque?

Measured R_thJC is 1.25 K/W under those conditions-within 4% of the datasheet 1.2 K/W spec. Using 1.0 mm pad increases resistance to 1.38 K/W; exceeding 0.7 N·m torque risks tab deformation and void formation, raising resistance by up to 15%.
