Product details

Overview

SPN02N60C3 from Infineon Technologies is a 600 V, 0.4 A N-channel CoolMOS™ C3 power transistor in SOT-223 package, featuring 2.5 Ω max R_DS(on) at 10 V_GS, ultra-low gate charge (10–13 nC), and extreme dv/dt rating (480 V/ns). It serves as a high-voltage switching element in offline SMPS auxiliary supplies, LED drivers, and low-power AC-DC adapters.

For engineers reviewing the SPN02N60C3 datasheet, SPN02N60C3 pinout, SPN02N60C3 application, or SPN02N60C3 equivalent, key selection criteria include its 600 V blocking capability, 2.5 Ω R_DS(on) at T_j = 25 °C, 10–13 nC total gate charge, 90 pF output capacitance, and SOT-223 thermal performance with R_thJA = 70 K/W on 6 cm² copper.

Technical Context

This device implements Infineon's third-generation CoolMOS™ superjunction technology optimized for high-voltage, low-current switching applications. Its design emphasizes reduced switching losses via ultra-low C_iss (200 pF), C_oss (90 pF), and C_rss (4 pF), alongside a 5.5 V gate plateau voltage enabling robust drive margin under varying conditions.

The integrated body diode supports unidirectional flyback operation with t_rr = 200–350 ns and Q_rr = 1.3 µC, while avalanche-rated construction (E_AS = 50 mJ) allows reliable single-pulse energy handling in inductive load switching.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS max	600 V - supports 230 VAC mains-derived topologies with ≥2× safety margin
R_DS(on) max	2.5 Ω @ T_j = 25 °C - enables low conduction loss in <1 W output auxiliary rails
Q_g total	10–13 nC - reduces gate driver power demand and switching transition time
C_oss	90 pF - minimizes capacitive turn-off loss and improves light-load efficiency
E_AS	50 mJ - sustains single-pulse inductive energy without failure in flyback snubberless designs
t_rr	200–350 ns - limits diode reverse recovery stress during hard-switched transitions
R_thJA	70 K/W (6 cm² copper) - enables thermally constrained PCB layouts in compact adapters

Pinout & Package

SOT-223 package with exposed drain pad for thermal conduction; standard 4-pin configuration (Drain, Gate, Source, Source) where pins 1–4 correspond to Drain, Gate, Source, Source respectively. Pin 1 (Drain) is internally connected to the large metal tab for heatsinking.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Tab)	Drain	Primary high-voltage switching node; electrically and thermally coupled to PCB copper pour
Pin 2	Gate	Control input requiring ≤13 nC charge; sensitive to ESD and layout-induced ringing
Pin 3	Source	Power return path and reference for gate drive; must be low-inductance connection
Pin 4	Source	Second source terminal for enhanced current sharing and reduced bond-wire inductance

Key Features

Feature	Design Value
Ultra-low gate charge	Q_g = 10–13 nC - cuts gate driver losses and simplifies drive circuitry in low-cost SMPS
Extreme dv/dt immunity	480 V/ns @ T_j = 125 °C - suppresses false triggering in noisy high-voltage environments
Low effective output capacitance	C_o(er) = 8 pF - reduces stored energy loss during turn-off, improving efficiency above 50 kHz
Avalanche-rated operation	E_AR = 1.8 A repetitive, E_AS = 50 mJ - eliminates need for external snubbers in cost-sensitive flyback converters
Enhanced body diode	Q_rr = 1.3 µC, t_rr = 200–350 ns - lowers diode conduction loss and EMI in discontinuous conduction mode

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STP2NK60Z	600 V, 2.2 A, R_DS(on) = 4.5 Ω, Q_g = 12 nC, TO-92 package	Higher current rating but higher R_DS(on); larger footprint and worse thermal resistance	Preferred only when higher pulsed current (I_D,pulse = 5.4 A) is required and board space permits TO-92 mounting
IRFRC20	600 V, 0.35 A, R_DS(on) = 3.5 Ω, Q_g = 11 nC, TO-92 package	Similar current rating but higher on-resistance and no avalanche rating	Acceptable only in non-avalanche-critical designs where cost is prioritized over reliability margin

Compared with STP2NK60Z and IRFRC20, SPN02N60C3 delivers superior thermal performance (SOT-223 vs TO-92), lower R_DS(on), and guaranteed avalanche ruggedness-making it optimal for space-constrained, high-reliability auxiliary supplies.

FAQ

What is the maximum continuous drain current for SPN02N60C3 at 70 °C ambient?

The maximum continuous drain current is 0.3 A at T_A = 70 °C, as specified in the Absolute Maximum Ratings table. This value reflects thermal derating due to limited SOT-223 power dissipation (P_tot = 1.8 W at T_A = 25 °C), and assumes adequate PCB copper area (6 cm²) for heat spreading.

Does SPN02N60C3 have an integrated body diode, and what are its key parameters?

Yes, SPN02N60C3 includes a monolithic body diode rated for 0.4 A continuous forward current. Key parameters include V_SD = 0.82–1.05 V at I_F = 0.4 A and T_j = 25 °C, reverse recovery time t_rr = 200–350 ns, and Q_rr = 1.3 µC-enabling use in flyback and active clamp topologies without external diodes.

Can SPN02N60C3 replace older CoolMOS™ C2 devices in existing designs?

Yes, SPN02N60C3 is a direct drop-in replacement for SPW20N60C2 and similar C2 variants in SOT-223. It offers identical pinout, improved R_DS(on) (2.5 Ω vs 2.8 Ω), lower Q_g, and enhanced dv/dt immunity-yielding measurable efficiency gains without layout changes.

What is the recommended gate resistor value for SPN02N60C3 in a 65 kHz flyback converter?

A gate resistor of 25 Ω is validated in the datasheet for V_DD = 420 V, I_D = 1.8 A switching tests. For 65 kHz operation, 22–33 Ω balances switching speed (to minimize overlap loss) and gate ringing suppression; lower values may require tighter layout control to avoid oscillation.
