Product details

Overview

SPN04N60S5 from Infineon Technologies is a 600 V, 0.95 Ω R_DS(on) CoolMOS™ superjunction N-channel power MOSFET in SOT-223 package, rated for 0.8 A continuous drain current at 25 °C and optimized for high-voltage, low-power SMPS flyback converters. It features ultra-low gate charge (17 nC), extreme dv/dt rating (20 V/ns), and integrated body diode with 200 ns reverse recovery time.

For engineers reviewing the SPN04N60S5 datasheet, SPN04N60S5 pinout, SPN04N60S5 application, or SPN04N60S5 equivalent, key selection criteria include its 600 V breakdown voltage, 0.95 Ω R_DS(on) at 10 V_GS, SOT-223 thermal performance (R_thJA = 70 K/W with 6 cm² copper), and suitability for compact offline AC/DC adapters under 15 W.

Technical Context

This device implements Infineon's second-generation CoolMOS™ technology, enabling superior conduction-loss-to-capacitance trade-off versus planar MOSFETs. Its 600 V V_(BR)DSS is temperature-stable (±2% over −55 to +150 °C), and effective output capacitance (C_o(er) = 20 pF) minimizes switching energy loss during hard-switched transitions.

The MOSFET supports gate drive with standard 10 V logic-level signals and exhibits robust avalanche capability (V_(BR)DS = 700 V at I_D = 4.5 A). Its 9.2 nC Q_gd and 4.1 nC Q_gs enable fast, controllable turn-on/turn-off with minimal Miller-induced oscillation risk in flyback primary switches.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	600 V - Withstands full mains rectified voltage in universal-input (85–265 V_AC) flyback converters without derating.
R_DS(on)	0.95 Ω @ T_j = 25 °C - Enables <1.2 W conduction loss at 0.8 A, critical for thermally constrained SOT-223 layouts.
Q_g	17 nC - Reduces gate driver power demand and allows use of low-cost, low-current controllers (e.g., ICE2Axx).
dv/dt Rating	20 V/ns - Ensures reliable operation under fast voltage transients common in discontinuous conduction mode (DCM) flyback.
C_iss	600 pF - Low input capacitance reduces gate drive loop instability and EMI generation during switching.
t_r/t_f	20 ns / 30 ns - Supports >200 kHz switching frequencies while maintaining low switching loss in compact adapters.
V_SD	0.85–1.05 V - Body diode forward voltage enables synchronous rectification-free designs with predictable conduction loss.

Pinout & Package

SOT-223 package with exposed drain pad for enhanced thermal dissipation on PCB; standardized 4-pin footprint (pin 1: Gate, pin 2: Drain, pin 3: Source, pin 4: Drain - internally connected to pin 2).

Pin/Terminal	Circuit Role	Design Meaning
Pin 1	Gate	Control terminal; requires ≤10 V logic-level drive; 200 nA leakage ensures low standby current.
Pin 2	Drain	Main high-side power node; electrically tied to exposed copper pad for thermal path to PCB.
Pin 3	Source	Reference node for gate drive; connects to primary ground in flyback topologies.
Pin 4	Drain (redundant)	Internal connection to Pin 2; used for mechanical stability and additional thermal conduction to PCB.

Key Features

Feature	Design Value
Ultra-low gate charge	Q_g = 17 nC enables efficient 200+ kHz operation with minimal gate driver stress and heat.
Extreme dv/dt immunity	20 V/ns rating prevents spurious turn-on during transformer leakage spikes in flyback circuits.
Low effective output capacitance	C_o(er) = 20 pF reduces stored energy (E_oss ≈ 2.5 µJ at 400 V), cutting turn-off loss by ~35% vs comparable planar MOSFETs.
Improved transconductance	g_fs = 1 S ensures stable gain and tight V_GS(th) control (3.5–5.5 V) across temperature for predictable turn-on timing.
Enhanced body diode	Q_rr = 1.2 µC and t_rr = 200 ns support quasi-resonant operation without external snubbers.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STP4NK60ZFP	600 V, 1.5 Ω R_DS(on), 12 nC Q_g, TO-92 package	Higher R_DS(on) increases conduction loss; TO-92 limits thermal performance vs SOT-223	Prefer when board space is unrestricted and cost sensitivity outweighs efficiency targets.
FQP4N60	600 V, 1.8 Ω R_DS(on), 22 nC Q_g, TO-220FP package	Larger footprint and higher switching loss; lacks dv/dt rating specification	Select only if existing TO-220FP layout prohibits SOT-223 rework and 15 W output is not required.

Compared with STP4NK60ZFP and FQP4N60, SPN04N60S5 delivers 37% lower R_DS(on) and 2× better thermal resistance in SOT-223, making it uniquely suitable for space-constrained, high-efficiency <15 W offline converters where board area and thermal headroom are limiting.

FAQ

What is the maximum continuous drain current for SPN04N60S5 at 70 °C ambient?

The maximum continuous drain current is 0.65 A at T_A = 70 °C, as specified in the Absolute Maximum Ratings table. This reflects thermal derating due to reduced heat dissipation at elevated ambient temperatures with the SOT-223 package on standard FR4 PCB.

Can SPN04N60S5 be used in avalanche mode?

Yes - SPN04N60S5 is rated for unclamped inductive switching with V_(BR)DS = 700 V at I_D = 4.5 A, confirming rugged avalanche capability. However, repetitive avalanche operation is not recommended; design must ensure energy per pulse stays within the SOA curve limits shown on Page 5.

What is the typical gate threshold voltage range, and how does it affect drive requirements?

V_GS(th) ranges from 3.5 V to 5.5 V at I_D = 200 µA. This ensures reliable turn-on with 5 V microcontroller outputs but mandates ≥6 V gate drive for full enhancement at high junction temperatures, where R_DS(on) increases significantly above 100 °C.

How does the body diode's reverse recovery performance impact flyback design?

With t_rr = 200 ns and Q_rr = 1.2 µC, the body diode enables clean zero-current switching in DCM flyback without external snubbers. This reduces EMI and eliminates need for ultra-fast external diodes in cost-sensitive designs below 15 W.
