Product details

Overview

SPN01N60C3 from Infineon Technologies is a 600 V, 0.3 A Cool MOS™ N-channel power transistor in SOT-223 package, featuring 6 Ω R_DS(on) at 10 V_GS, ultra-low gate charge (3.9 nC typ), and extreme dv/dt rating (50 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 SPN01N60C3 datasheet, SPN01N60C3 pinout, SPN01N60C3 application, or SPN01N60C3 equivalent, key selection criteria include its 600 V breakdown voltage, 0.3 A continuous drain current, 1.8 W power dissipation at 25 °C, SOT-223 thermal performance (R_thJA = 72 K/W with 6 cm² copper), and body diode reverse recovery time (200–340 ns).

Technical Context

This device employs Infineon's Cool MOS™ C3 technology, optimized for high-voltage, low-current switching with enhanced transconductance (0.45 S typ) and minimized effective capacitances (C_iss = 100 pF, C_oss = 40 pF, C_rss = 2.5 pF). Its gate threshold voltage (2.3–3.7 V) enables reliable turn-on with standard 5 V logic-level drivers.

The transistor supports hard-switched topologies up to 350 V DC bus, with fast switching times (t_d(on) = 45 ns, t_r = 30 ns, t_d(off) = 60 ns, t_f = 30 ns) and robust avalanche capability (V_(BR)DS = 700 V). Its body diode exhibits V_SD = 0.85–1.05 V and Q_rr = 0.45 µC, suitable for non-synchronous flyback and buck-derived converters.

Key Specifications

Parameter	Value and Actual Design Meaning
V_(BR)DSS	600 V - Withstands 600 V drain-source blocking voltage at T_j = 25 °C, derating to ~540 V at −60 °C and ~660 V at 150 °C
R_DS(on)	6 Ω max at V_GS = 10 V, I_D = 0.5 A, T_j = 25 °C - Defines conduction loss in low-current, high-voltage applications
Q_g	3.9–5 nC - Low total gate charge reduces driver power and enables efficient 100–500 kHz switching
I_D cont	0.3 A at T_A = 25 °C - Continuous current rating limited by SOT-223 package thermal resistance (R_thJA = 72 K/W)
t_r/t_f	30/30 ns - Fast rise/fall times minimize switching losses in hard-switched topologies
dv/dt	50 V/ns - High immunity to parasitic turn-on in noisy high-dv/dt environments (e.g., flyback snubbers)
V_GS(th)	2.3–3.7 V - Ensures clean turn-on with 3.3 V or 5 V microcontroller GPIO without level-shifting

Pinout & Package

SOT-223 package with exposed drain pad (Pin 2) for thermal conduction to PCB copper; 4-pin configuration with Pin 1 = Gate, Pin 2 = Drain, Pin 3 = Source, Pin 4 = Source (dual-source tie).

Pin/Terminal	Circuit Role	Design Meaning
Pin 1	Gate	Control terminal; accepts 0–10 V drive; low input capacitance (C_iss = 100 pF) eases driver design
Pin 2	Drain	Main high-side switching node; electrically connected to exposed thermal pad for heat transfer to PCB
Pins 3 & 4	Source	Power return path; dual-source pins reduce source inductance and improve stability in high-dv/dt operation

Key Features

Feature	Design Value
Ultra-low gate charge	Q_g = 3.9–5 nC enables efficient 5 V logic-level driving and reduces gate driver losses
Extreme dv/dt rating	50 V/ns withstand capability prevents false triggering in high-noise flyback and ZVS circuits
Improved transconductance	g_fs = 0.45 S ensures stable gain and predictable V_GS-I_D relationship across temperature
Low effective output capacitance	C_oss = 40 pF minimizes energy loss during turn-off and improves light-load efficiency
Enhanced body diode performance	Q_rr = 0.45 µC and t_rr = 200–340 ns support quasi-resonant and discontinuous conduction mode operation

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STP1NK60Z	600 V, 0.25 A, R_DS(on) = 11 Ω, Q_g = 4.5 nC, TO-92 package	Higher R_DS(on) increases conduction loss; TO-92 limits thermal performance vs. SOT-223	Prefer SPN01N60C3 when board space and thermal management require SMT packaging and lower on-resistance.
FQP1N60	600 V, 1 A, R_DS(on) = 11.5 Ω, Q_g = 12 nC, TO-220 package	Higher current rating but larger size and higher gate charge; unsuitable for compact, low-power designs	Choose SPN01N60C3 for SMT integration, lower switching loss, and reduced PCB area in sub-1 W systems.

Compared with STP1NK60Z and FQP1N60, SPN01N60C3 delivers superior thermal performance in SMT form factor, lower R_DS(on) for reduced conduction loss, and lower Q_g for higher-frequency operation-making it optimal for space-constrained, low-power, high-reliability AC-DC stages.

FAQ

Is SPN01N60C3 suitable for 5 V logic-level gate drive?

Yes. Its gate threshold voltage (V_GS(th)) ranges from 2.3 V to 3.7 V at 250 µA, ensuring full enhancement with standard 5 V microcontroller outputs. The low gate charge (3.9–5 nC) further reduces driver loading, enabling direct GPIO control without external buffers in low-frequency applications.

What is the maximum safe operating voltage for SPN01N60C3 in continuous DC operation?

The absolute maximum drain-source voltage is 650 V at T_jmax, but the rated breakdown voltage V_(BR)DSS is 600 V at 25 °C. For reliable long-term operation, design margins should limit steady-state V_DS to ≤480 V, especially under transient conditions where dv/dt stress and temperature derating apply.

Can SPN01N60C3 replace a bipolar transistor in an existing linear regulator design?

No. SPN01N60C3 is a MOSFET designed for switching operation-not linear regulation. Its R_DS(on) is specified only in saturation, and it lacks safe operating area (SOA) data for linear-mode use. Attempting linear operation risks thermal runaway due to positive temperature coefficient of R_DS(on) and insufficient SOA rating.

How does the SOT-223 package affect thermal performance compared to TO-92?

The SOT-223 offers significantly better thermal resistance: R_thJA = 72 K/W (with 6 cm² copper) versus ~200 K/W for TO-92. Its exposed drain pad allows direct thermal coupling to PCB copper, enabling higher power dissipation (1.8 W vs. ~0.5 W) and improved reliability in sustained operation at ambient temperatures up to 70 °C.
