Product details

Overview

SPU02N60C3BKMA1 from Infineon Technologies is a 600 V, 2.5 A N-channel enhancement-mode power MOSFET in TO-252 (DPAK) package, featuring R_DS(on) = 3.0 Ω at V_GS = 10 V and T_j = 25 °C, 100% avalanche-rated, and optimized for high-voltage flyback and SMPS primary-side switching in industrial AC/DC adapters.

For engineers reviewing the SPU02N60C3BKMA1 datasheet, SPU02N60C3BKMA1 pinout, SPU02N60C3BKMA1 application, or SPU02N60C3BKMA1 equivalent, key selection criteria include its 600 V V_DSS, ultra-low gate charge (Q_g = 8.5 nC), 15 V/ns dv/dt ruggedness, and thermally robust TO-252 footprint with low R_thJC = 3.5 K/W.

Technical Context

This MOSFET employs Infineon's CoolMOS™ C3 technology, delivering improved E_oss-related switching efficiency and reduced turn-on/turn-off losses versus prior generations. Its fixed gate plateau voltage of 4.5 V enables stable drive under wide V_DD conditions in offline converters.

The device supports repetitive avalanche operation up to I_AR = 1.2 A at V_DD = 400 V and features a body diode with t_rr = 170 ns and Q_rr = 1.1 µC - critical for ZVS quasi-resonant topologies and hard-switched PFC stages.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	600 V - supports 400 V DC-link designs with ≥50% safety margin against transients
R_DS(on) max	3.0 Ω @ V_GS = 10 V, T_j = 25 °C - enables <1.5 W conduction loss at 2.5 A continuous drain current
Q_g	8.5 nC - reduces gate driver power demand and enables >100 kHz operation in compact flyback controllers
E_oss	19 nJ @ V_DS = 400 V - lowers capacitive switching loss during hard commutation
t_r/t_f	12/15 ns - supports fast edge control in noise-sensitive EMI-constrained applications
T_j max	150 °C - allows operation in sealed industrial enclosures without forced airflow
I_D cont	2.5 A @ T_C = 100 °C - defines thermal derating limit on standard FR4 PCB with 1 cm² copper pour

Pinout & Package

SPU02N60C3BKMA1 uses the TO-252 (DPAK) surface-mount package with exposed drain pad for thermal and electrical connection. The package complies with MSL Level 3 reflow requirements and supports soldering per IPC-J-STD-020.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Source)	Source terminal	Low-side reference node; connects directly to ground plane or current-sense resistor
Pin 2 (Gate)	Control input	High-impedance MOS gate requiring <10 kΩ series resistance to damp ringing
Pin 3 (Drain)	Power output	Exposed copper pad - must be soldered to ≥1 cm² thermal pad for R_thJA ≤ 60 K/W

Key Features

Feature	Design Value
100% avalanche rated	Single-pulse E_AS = 260 mJ at T_j = 25 °C - eliminates need for external snubbers in inductive load switching
Ultra-low effective output capacitance	C_oss,er = 22 pF - minimizes energy loss during zero-voltage switching transitions
High dv/dt ruggedness	15 V/ns - prevents false turn-on in high-noise motor drive or industrial PLC I/O modules
Optimized body diode	Q_rr = 1.1 µC, t_rr = 170 ns - reduces reverse recovery loss in synchronous rectifier and LLC resonant converters
Thermally enhanced DPAK	R_thJC = 3.5 K/W - enables 2.5 A continuous operation on minimal PCB copper area

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
STP2NK60ZFP	R_DS(on) = 3.3 Ω, Q_g = 11 nC, no specified dv/dt rating	Lacks documented 15 V/ns immunity; requires additional gate clamping in noisy environments	Acceptable where cost sensitivity outweighs EMI robustness requirements
FQP2N60	R_DS(on) = 3.6 Ω, Q_g = 13 nC, E_AS not guaranteed	No avalanche rating - unsuitable for inductive load switching without external protection	Only suitable for resistive or lightly inductive loads with strict transient suppression

Compared with STP2NK60ZFP and FQP2N60, SPU02N60C3BKMA1 delivers lower conduction loss, faster switching, and guaranteed avalanche performance - making it preferred for unclamped inductive switching and compact high-efficiency designs.

FAQ

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

The SPU02N60C3BKMA1 supports I_D = 2.5 A continuously at T_C = 100 °C, verified per datasheet Figure 7. This rating assumes mounting on a standard FR4 PCB with ≥1 cm² 35 µm copper drain pad and natural convection cooling - no heatsink required for typical adapter applications.

Does this MOSFET require a gate resistor for stability?

Yes - a 10 Ω to 22 Ω series gate resistor is recommended to suppress high-frequency oscillation caused by PCB trace inductance and gate capacitance interaction. The device's low input capacitance (C_iss = 220 pF) makes it especially sensitive to ringing without proper damping.

Can SPU02N60C3BKMA1 replace older CoolMOS™ C2 devices?

Yes - it is a direct drop-in replacement for SPU02N60C2 variants, offering identical pinout, voltage rating, and thermal footprint. Key improvements include 15% lower R_DS(on), 20% lower Q_g, and enhanced dv/dt immunity - enabling higher efficiency without layout changes.

Is the body diode suitable for synchronous rectification?

No - the body diode has relatively high Q_rr (1.1 µC) and forward voltage (V_SD = 1.3 V), making it unsuitable for high-frequency synchronous rectification. It is designed for freewheeling and clamping, not active rectification; external Schottky diodes or dedicated SR controllers are recommended for that function.
