Product details

Overview

SPN03N60S5 from Infineon Technologies is a 600 V, 1.4 Ω R_DS(on), 0.7 A Cool MOS™ power transistor in SOT-223 package, designed for high-voltage switching in offline SMPS, auxiliary power supplies, and LED drivers. It features ultra-low gate charge (12.8 nC), extreme dv/dt rating (20 V/ns), and improved transconductance (0.73 S).

For engineers reviewing the SPN03N60S5 datasheet, SPN03N60S5 pinout, SPN03N60S5 application, or SPN03N60S5 equivalent, key selection criteria include its 600 V breakdown voltage, thermal resistance R_thJA of 62 K/W (6 cm² copper), body diode reverse recovery time (200 ns), and SOT-223 footprint compatibility with space-constrained board layouts.

Technical Context

This N-channel enhancement-mode MOSFET employs Infineon's Cool MOS™ technology to reduce switching losses while maintaining ruggedness in high-dv/dt environments. Its low C_iss (440 pF) and C_rss (12 pF) enable fast switching at high frequencies, and the 8 V gate plateau voltage ensures stable turn-on under varying drive conditions.

The device integrates a robust intrinsic body diode with 0.85–1.05 V forward voltage and 0.9 µC reverse recovery charge, supporting discontinuous conduction mode (DCM) flyback and resonant topologies without external diode supplementation.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	600 V - supports primary-side switching in universal-input AC/DC adapters up to 265 V_AC.
R_DS(on)	1.4 Ω @ T_j = 25°C - enables low conduction loss in <1 W auxiliary supplies with minimal heatsinking.
Q_g	12.8 nC - reduces gate driver power demand and allows use of low-cost, low-current drivers.
dv/dt Rating	20 V/ns - withstands steep voltage transients in hard-switched flyback and PFC stages without false triggering.
C_iss/C_oss	440 pF / 230 pF - minimizes Miller effect and improves EMI behavior in high-frequency operation (>100 kHz).
T_j Range	−55 °C to +150 °C - qualified for industrial ambient environments and sealed enclosure applications.
P_tot	1.8 W @ T_A = 25°C - defines maximum continuous dissipation on standard FR4 PCB with 6 cm² copper pour.

Pinout & Package

SOT-223 package with 4-pin configuration (pin 1: Gate; pin 2: Drain; pin 3: Source; pin 4: Drain tab). The exposed drain pad (pin 2 & 4) provides low thermal resistance path to PCB copper area.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1	Gate	Control terminal requiring ≤10 V drive; low input capacitance (440 pF) eases driver design.
Pin 2 & Pin 4	Drain (common tab)	High-voltage output node; electrically and thermally connected to PCB copper pour for heat dissipation.
Pin 3	Source	Reference node for gate drive; tied to power ground in common-source topology.

Key Features

Feature	Design Value
Ultra-low gate charge	Q_g = 12.8 nC - cuts switching energy loss by >30% vs. standard 600 V MOSFETs in 65–100 kHz SMPS.
Extreme dv/dt immunity	20 V/ns - eliminates need for snubbers in compact flyback designs operating near EMI limits.
Low effective output capacitance	C_oss = 230 pF - reduces turn-off loss and improves light-load efficiency in DCM operation.
Enhanced body diode performance	Q_rr = 0.9 µC, t_rr = 200 ns - enables reliable zero-voltage switching (ZVS) in quasi-resonant converters.
Improved transconductance	g_fs = 0.73 S - delivers tighter V_GS(th) control (3.5–5.5 V) and reduced gate drive sensitivity to temperature drift.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STP3NK60ZFP	R_DS(on) = 2.2 Ω, Q_g = 14 nC, TO-92 package	Higher conduction loss; limited to <0.5 W continuous dissipation	Prefer when legacy TO-92 footprint must be retained and efficiency is secondary to cost.
FQP3N60	R_DS(on) = 2.4 Ω, C_iss = 520 pF, TO-220FP package	Larger footprint; higher switching loss due to elevated capacitance	Select only if board layout requires through-hole mounting and thermal mass from TO-220FP aids cooling.

Compared with STP3NK60ZFP and FQP3N60, SPN03N60S5 delivers superior power density via SOT-223 packaging, 18% lower R_DS(on), and 15% lower Q_g, making it optimal for miniaturized, thermally constrained offline power designs.

FAQ

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

The SPN03N60S5 supports 0.4 A continuous drain current at T_A = 70°C with standard PCB layout (6 cm² copper). This derating reflects thermal resistance R_thJA = 62 K/W and junction-to-ambient power dissipation limit. Exceeding this current risks thermal runaway unless additional heatsinking or forced airflow is applied.

Does SPN03N60S5 require a gate resistor for safe operation?

Yes - a gate resistor (typically 10–47 Ω) is required to dampen ringing caused by parasitic inductance and prevent oscillation during switching transitions. The 12.8 nC total gate charge and 7.5 nC gate-to-drain charge make proper gate drive impedance critical to avoid shoot-through and ensure clean turn-on/turn-off waveforms.

Can SPN03N60S5 replace a bipolar transistor in existing designs?

No - SPN03N60S5 is a voltage-controlled MOSFET, not a current-controlled BJT. Direct replacement would require redesigning the base/gate drive circuitry, removing current-limiting resistors, and verifying gate voltage compatibility (0–10 V logic-level drive vs. BJT's ~0.7 V V_BE). Its low gate current simplifies drive but changes dynamic behavior significantly.

Is the SOT-223 package lead-free and RoHS-compliant?

Yes - SPN03N60S5 is manufactured per RoHS Directive 2011/65/EU and uses lead-free solderable terminations. The device meets JEDEC J-STD-020 moisture sensitivity level (MSL) 1 and supports standard reflow profiles up to 260°C peak temperature for 10 seconds, as verified in the official Infineon datasheet Rev. 2.2.
