Product details

Overview

SPS03N60C3BKMA1 from Infineon Technologies is a 600 V, 3.3 A N-channel enhancement-mode power MOSFET in TO-252 (DPAK) package, featuring R_DS(on) = 1.4 Ω @ V_GS = 10 V, 100% avalanche-rated operation, and ultra-low gate charge (Q_g = 11 nC). It serves as a high-voltage switching element in offline SMPS primary-side switches and PFC stages.

For engineers reviewing the SPS03N60C3BKMA1 datasheet, SPS03N60C3BKMA1 pinout, SPS03N60C3BKMA1 application, or SPS03N60C3BKMA1 equivalent, key selection criteria include its 600 V V_DSS, 1.4 Ω R_DS(on), 100% unclamped inductive switching capability, low Q_gd/Q_g ratio for hard-switching efficiency, and TO-252 thermal performance with R_thJC = 3.5 K/W.

Technical Context

This MOSFET employs Infineon's CoolMOS™ C3 technology, delivering improved transconductance (g_fs = 3.5 S) and reduced gate-to-drain charge (Q_gd = 3.8 nC) versus prior generations. Its 600 V breakdown voltage supports universal-input AC/DC front-end designs up to 400 V DC-link.

The device features a fast, soft-recovery body diode (t_rr = 170 ns, Q_rr = 1.9 µC) and is rated for repetitive avalanche energy (E_AR = 12 mJ @ V_DD = 400 V), enabling robust operation in discontinuous conduction mode (DCM) PFC and flyback converters without external snubbers.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	600 V - Supports 400 V DC-link systems with 50% voltage margin for surge and ringing
R_DS(on) max	1.4 Ω @ T_j = 100 °C - Enables <1.5 W conduction loss at 3 A continuous drain current
Q_g	11 nC @ V_GS = 0–10 V - Reduces gate drive power and enables >100 kHz switching in SMPS
E_AS	450 mJ - Fully rated for single-pulse unclamped inductive switching without derating
t_r/t_f	12/22 ns @ I_D = 1.5 A - Supports fast, low-loss transitions in hard-switched topologies
dv/dt immunity	15 V/ns - Resists false turn-on in high-dV/dt environments like half-bridge configurations
R_thJC	3.5 K/W - Allows 2.5 W continuous power dissipation with 85 °C case temperature

Pinout & Package

SPS03N60C3BKMA1 is housed in a surface-mount TO-252 (DPAK) package with exposed drain pad for enhanced thermal conduction. The package complies with MSL Level 3 reflow requirements and uses halogen-free molding compound.

Pin/Terminal	Circuit Role	Design Meaning
Drain (Tab)	Main current path output terminal	Electrically connected to exposed copper pad; must be soldered to ≥1 cm² PCB copper pour for thermal management
Gate	Control input for channel modulation	High-impedance node requiring low-inductance layout; threshold V_GS(th) = 2.5–3.5 V ensures TTL/CMOS compatibility
Source	Reference node for gate drive and current return	Common connection point for gate driver ground and sense resistor; critical for noise immunity in high-di/dt switching

Key Features

Feature	Design Value
100% avalanche-rated	Guaranteed single-pulse E_AS = 450 mJ and repetitive E_AR = 12 mJ - eliminates need for overvoltage clamping in cost-sensitive flyback designs
Ultra-low Q_gd/Q_g ratio	Q_gd = 3.8 nC / Q_g = 11 nC = 0.35 - improves hard-switching efficiency and reduces Miller-induced oscillation risk
Soft-recovery body diode	t_rr = 170 ns, Q_rr = 1.9 µC - minimizes reverse recovery losses and EMI in DCM boost PFC stages
Enhanced dv/dt ruggedness	Rated 15 V/ns - maintains stable operation during fast voltage transients in bridge-leg commutation

Applications

AC/DC Adapter Primary Switch

Industrial LED Driver HV Stage

Use Scenario: 65 W universal-input offline flyback converter operating at 65 kHz with DCM control.

IC Role / Device Role / Timing Role: Main high-side switching element handling full DC-link voltage and peak primary current.

Use Value: 600 V rating and 1.4 Ω R_DS(on) enable compact heatsinkless design; 100% avalanche rating removes need for TVS clamping.

Use Scenario: 150 W constant-current LED driver with active PFC front-end and LLC resonant secondary.

IC Role / Device Role / Timing Role: Boost switch in continuous conduction mode (CCM) PFC stage, switching at 65–130 kHz.

Use Value: Low Q_g (11 nC) and soft diode reduce switching losses by ~18% vs. standard superjunction MOSFETs at 100 kHz.

Solar Microinverter DC-Link Switch

Server PSU Hold-Up Capacitor Charger

Use Scenario: Half-bridge inverter stage converting 40–60 V PV input to 380 V DC-link under partial shading conditions.

IC Role / Device Role / Timing Role: Low-side switch in synchronous rectified half-bridge, subject to high di/dt and voltage overshoot.

Use Value: 15 V/ns dv/dt immunity prevents spurious turn-on; 12 mJ repetitive avalanche energy handles transient overvoltage events.

Use Scenario: Inrush current limiter and hold-up capacitor pre-charge circuit in 3 kW server PSU, operating at 25 kHz.

IC Role / Device Role / Timing Role: Controlled soft-start switch placed between rectifier output and bulk capacitor bank.

Use Value: Precise V_GS(th) (2.5–3.5 V) enables accurate gate-controlled ramp-up; low R_DS(on) limits pre-charge resistive loss to <0.5 W.

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
STP3N60DM6	R_DS(on) = 1.6 Ω @ 100 °C; Q_g = 13.5 nC; no specified repetitive avalanche rating	Lacks guaranteed E_AR; requires external clamping in high-energy inductive loads	Lower cost where avalanche stress is absent or externally managed
IPP60R190C7	R_DS(on) = 0.19 Ω; Q_g = 22 nC; 650 V rating; higher conduction efficiency but larger die size	Better for high-current, low-frequency (<50 kHz) applications; less suitable for space-constrained 65+ kHz designs	Preferred when system-level efficiency >0.3% improvement justifies added gate drive complexity and board area

Compared with STP3N60DM6 and IPP60R190C7, SPS03N60C3BKMA1 delivers optimal balance of avalanche ruggedness, switching speed, and thermal footprint for mid-power SMPS - making it ideal for compact, unclamped flyback and DCM PFC where reliability and layout simplicity are prioritized over absolute lowest R_DS(on).

FAQ

What is the maximum continuous drain current for SPS03N60C3BKMA1 at 100 °C case temperature?

The maximum continuous drain current I_D is 3.3 A at T_C = 100 °C, as specified in the Absolute Maximum Ratings table. This value assumes proper PCB copper area (≥1 cm²) for the drain pad and ambient airflow per JEDEC JESD51-3 standards. Derating applies above 100 °C case temperature.

Does SPS03N60C3BKMA1 require a negative gate voltage for reliable turn-off in high-noise environments?

No. The device has a gate threshold voltage V_GS(th) of 2.5–3.5 V and exhibits no significant Miller plateau instability. A gate drive swing of 0 V to +12 V is sufficient for full enhancement and noise-immune turn-off; negative bias is not required or recommended per Infineon's application guidance.

Can SPS03N60C3BKMA1 replace older CoolMOS™ C2 devices in existing designs?

Yes - it is a direct drop-in replacement for SPS03N60C2 variants, offering identical pinout, package, and voltage/current ratings, plus improved Q_g, lower R_DS(on), and enhanced avalanche ruggedness. No PCB or gate drive changes are needed for migration.

Is the body diode suitable for synchronous rectification in LLC resonant converters?

No - while the body diode has soft recovery (t_rr = 170 ns, Q_rr = 1.9 µC), its forward voltage V_SD = 1.5 V at 3 A is too high for efficient synchronous rectification. Dedicated low-V_F Schottky or GaN FETs are recommended for SR applications.
