Infineon Technologies SPS03N60C3

Overview

SPS03N60C3 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 at V_GS = 10 V and T_j = 25 °C, 100% avalanche-rated, with ultra-low gate charge (Q_g = 11 nC) and high dv/dt ruggedness (15 V/ns). It serves as a primary switching device in offline SMPS, PFC stages, and industrial motor drives operating up to 60 kHz.

For engineers reviewing the SPS03N60C3 datasheet, SPS03N60C3 pinout, SPS03N60C3 application, or SPS03N60C3 equivalent, key selection criteria include its 600 V blocking voltage, 1.4 Ω on-resistance at 10 V gate drive, 100% unclamped inductive switching (UIS) rating, thermal resistance R_thJC = 3.5 K/W, and halogen-free packaging options (AT vs BT variants).

Technical Context

This MOSFET employs Infineon's latest CoolMOS™ C3 technology, delivering improved transconductance (g_fs = 3.5 S) and reduced gate-to-drain charge (Q_gd = 3.8 nC) for faster switching and lower E_on/E_off losses. Its optimized cell structure enables stable operation under high di/dt (≤400 A/µs) and repetitive avalanche stress without derating.

The device supports both high-side and low-side configurations in half-bridge topologies, with confirmed reverse diode recovery characteristics (t_rr = 170 ns, Q_rr = 0.9 µC at I_F = 3.3 A), and is qualified for reflow soldering (MSL3) in TO-252 packages with exposed drain pad for thermal enhancement.

FAQ

What is the maximum continuous drain current for SPS03N60C3 at 100 °C case temperature?

The maximum continuous drain current I_D is 2.2 A at T_C = 100 °C, as specified in the Absolute Maximum Ratings table. This reflects thermal limitation of the TO-252 package under real-world heatsinking conditions-not a device degradation threshold but a safe operating limit derived from R_thJC = 3.5 K/W and P_tot = 25 W.

Does SPS03N60C3 support gate drive voltages below 10 V?

Yes-SPS03N60C3 has a gate threshold voltage V_GS(th) of 2.0–4.0 V and achieves R_DS(on) ≤ 1.8 Ω at V_GS = 8 V (T_j = 25 °C). However, full specification compliance (e.g., 1.4 Ω R_DS(on)) requires V_GS ≥ 10 V, and operation below 5 V increases switching loss and reduces noise immunity.

Is the body diode suitable for synchronous rectification in a flyback converter?

The body diode exhibits t_rr = 170 ns and Q_rr = 0.9 µC at I_F = 3.3 A, with soft recovery behavior (I_RRM/I_F ≈ 1.7). While usable in low-frequency flyback (<65 kHz), it is not optimized for high-efficiency synchronous rectification-external Schottky or dedicated SR controller is recommended above 50 W.

How does the halogen-free version (SPS03N60C3AT) differ electrically from the standard version?

No electrical or thermal differences exist between SPS03N60C3AT (halogen-free) and SPS03N60C3BT (non-halogen-free). Both share identical die, R_DS(on), Q_g, avalanche rating, and thermal resistance. The distinction lies solely in mold compound chemistry-verified compliant with IEC 61249-2-21 and JEDEC J-STD-020.
