Product details

Overview

SPP03N60C3XKSA1 from Infineon Technologies is a 600 V, 3.3 A N-channel enhancement-mode power MOSFET in TO-220-3 package, featuring R_DS(on) = 2.4 Ω (max) at V_GS = 10 V and T_j = 25 °C, 15 V/ns dv/dt ruggedness, and repetitive avalanche rating up to 100 mJ. It serves as a high-voltage switching element in offline SMPS primary-side switches and PFC stages.

For engineers reviewing the SPP03N60C3XKSA1 datasheet, SPP03N60C3XKSA1 pinout, SPP03N60C3XKSA1 application, or SPP03N60C3XKSA1 equivalent, key selection criteria include its 600 V V_DSS, ultra-low gate charge (Q_G = 12 nC typ), full avalanche capability, thermal resistance R_thJC = 2.5 K/W, and body diode reverse recovery performance (Q_rr = 29 nC).

Technical Context

This MOSFET employs Infineon's CoolMOS™ C3 technology, delivering improved transconductance (g_fs = 2.5 S min) and reduced gate-to-drain charge (Q_gd = 4.5 nC typ) for faster switching with lower EMI. Its fully isolated TO-220-3 package enables direct heatsink mounting without insulation hardware.

The device supports periodic avalanche operation under defined conditions (E_AS = 100 mJ, I_AR = 3.3 A, V_DD = 400 V), and features a robust body diode with t_rr = 170 ns and Q_rr = 29 nC at I_F = 3.3 A, enabling reliable hard-switched flyback and resonant converter topologies.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	600 V - Withstands DC bus voltages up to 400 V in 85–265 VAC offline converters with margin
R_DS(on) max	2.4 Ω @ V_GS = 10 V, T_j = 25 °C - Enables low conduction loss in <10 W primary-side switch applications
Q_G typ	12 nC - Reduces gate drive power and allows use with low-current drivers (e.g., UC384x family)
E_AS	100 mJ - Supports single-pulse avalanche energy handling without failure in overvoltage transients
R_thJC	2.5 K/W - Enables 3.3 A continuous operation at T_C = 100 °C with standard heatsinking
dv/dt ruggedness	15 V/ns - Prevents spurious turn-on during fast voltage transitions in bridge-leg configurations
t_r/t_f	12/20 ns - Supports >100 kHz switching in DCM flyback and critical-conduction-mode PFC

Pinout & Package

TO-220-3 package: insulated plastic case with electrically isolated drain tab; requires no insulating washer when mounted to heatsink.

Pin/Terminal	Circuit Role	Design Meaning
1 (Gate)	Control input	High-impedance MOS gate requiring <12 nC total charge; sensitive to ESD; must be driven with low-impedance path
2 (Drain)	High-voltage power terminal	Connected to DC bus or transformer primary; electrically isolated tab enables direct heatsink mounting
3 (Source)	Power return and reference	Common node for gate driver return and current sensing; ties to primary ground in flyback/PFC designs

Key Features

Feature	Design Value
Repetitive avalanche rated	Enables reliable operation under transient overvoltage without external clamping in cost-sensitive SMPS
Ultra-low gate charge	Reduces switching losses by >30% vs. legacy 600 V MOSFETs at 65 kHz, easing thermal design
Improved transconductance	Delivers tighter V_GS(th) control (2–4 V) and stable on-resistance across temperature
Body diode with low Q_rr	Minimizes reverse recovery loss in discontinuous conduction mode (DCM) flyback converters
Full isolation (TO-220-3)	Eliminates need for mica washers or silicone pads-reduces assembly cost and thermal interface resistance

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STP3NK60ZFP	R_DS(on) = 2.2 Ω (lower), but Q_G = 18 nC (higher); no specified repetitive avalanche rating	Lacks documented avalanche endurance; requires external snubber in surge-prone environments	Prefer where gate drive strength is ample and surge immunity is not required
IPP60R190C6	650 V rating, R_DS(on) = 1.9 Ω, Q_G = 16 nC; TO-220FP package (non-isolated)	Requires insulating hardware; higher voltage margin useful only in 400 V+ DC link systems	Select when system DC bus exceeds 450 V or when lower R_DS(on) justifies added isolation complexity

Compared with STP3NK60ZFP and IPP60R190C6, SPP03N60C3XKSA1 uniquely combines certified repetitive avalanche operation, full isolation, and optimized Q_G/R_DS(on) trade-off for cost-sensitive, high-reliability 600 V SMPS designs.

FAQ

What is the maximum continuous drain current at 100 °C case temperature?

The SPP03N60C3XKSA1 supports I_D = 3.3 A continuous at T_C = 100 °C, verified per its Safe Operating Area (SOA) curve and thermal resistance R_thJC = 2.5 K/W. Derating is linear below 25 °C and follows SOA limits above 100 °C.

Does this MOSFET require a gate resistor for stability?

Yes-a gate resistor of 10–47 Ω is recommended to dampen parasitic oscillation and control dV/dt-induced shoot-through in half-bridge configurations. The device's low Q_gd (4.5 nC) makes it especially sensitive to layout-induced ringing without proper gate damping.

Can the body diode be used for synchronous rectification?

No-the body diode is not optimized for synchronous rectification. Its Q_rr = 29 nC and t_rr = 170 ns are typical for a high-voltage switching diode, not a low-loss SR diode. Dedicated SR controllers with external FETs are required for efficient secondary-side rectification.

Is the TO-220-3 package lead-free and RoHS-compliant?

Yes-SPP03N60C3XKSA1 carries the "XKSA1" suffix indicating lead-free (Pb-free), RoHS-compliant construction with halogen-free molding compound, per Infineon's qualification standards and JEDEC J-STD-020 reflow profile compliance.
