Product details

Overview

SPN02N60S5 from Infineon Technologies is a 600 V, 3 Ω R_DS(on), 0.4 A SOT-223 packaged CoolMOS™ power transistor optimized for high-voltage, low-power SMPS in auxiliary supplies, LED drivers, and offline adapters. It features ultra-low gate charge (7.4 nC), extreme dv/dt rating (20 V/ns), and improved transconductance (0.5 S).

For engineers reviewing the SPN02N60S5 datasheet, SPN02N60S5 pinout, SPN02N60S5 application, or SPN02N60S5 equivalent, key selection criteria include its 600 V breakdown voltage, thermal resistance of 110 K/W (R_thJA on 6 cm² PCB), 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 2nd-generation CoolMOS™ superjunction technology to reduce switching losses while maintaining rugged avalanche capability. Its gate threshold voltage (3.5–5.5 V) enables direct drive from standard logic-level controllers, and its low C_iss (250 pF) and C_rss (8 pF) support high-frequency operation up to 500 kHz.

The device integrates a fast-recovery body diode (t_rr = 200 ns, Q_rr = 0.7 µC) and is rated for continuous operation at T_j = 150 °C. Its safe operating area supports pulsed drain currents up to 2.2 A with t_p ≤ 10 ms under DC and transient conditions.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	600 V - Withstands full mains rectified voltage in 230 VAC systems without derating.
R_DS(on)	3 Ω @ T_j = 25 °C - Enables <1.2 W conduction loss at 0.4 A, suitable for sub-5 W standby supplies.
Q_g	7.4 nC - Reduces gate driver power demand and enables efficient 300–500 kHz switching in flyback converters.
dv/dt	20 V/ns - Ensures immunity to false turn-on during high-noise switching transitions in compact layouts.
t_r/t_f	15 ns / 30 ns - Supports fast edge control for EMI optimization in quasi-resonant topologies.
C_iss/C_oss	250 pF / 110 pF - Low input/output capacitance minimizes switching energy and improves light-load efficiency.
T_j max	+150 °C - Allows operation in sealed enclosures or high-ambient industrial environments without forced cooling.

Pinout & Package

SOT-223 package with exposed drain pad (Pin 2) for thermal conduction; 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; requires ≤10 V logic-level drive; low Q_gs (1.8 nC) reduces driver stress.
Pin 2	Drain	Main high-side switching node; thermally connected to PCB copper pour via exposed pad for R_thJS = 30 K/W.
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 = 7.4 nC enables use with low-power gate drivers (e.g., UC3842, TL494) without external buffers.
Extreme dv/dt rating	20 V/ns withstands rapid voltage transients in discontinuous conduction mode flyback converters.
Improved transconductance	g_fs = 0.5 S ensures stable gain and predictable current regulation across temperature.
Low effective output capacitance	C_oss = 110 pF reduces turn-off energy loss and improves zero-voltage switching margin.
Integrated fast body diode	t_rr = 200 ns, Q_rr = 0.7 µC minimizes reverse recovery loss in self-oscillating or QR flyback designs.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STP2NK60Z	600 V, 4.5 Ω R_DS(on), 2.2 A I_D, TO-92 package - higher R_DS(on), larger footprint, no dv/dt rating specified.	Limited to lower-efficiency 1–3 W adapters; unsuitable for space-constrained SMT designs.	Choose only if legacy TO-92 assembly infrastructure exists and thermal budget permits +0.6 W conduction loss.
FQP2N60	600 V, 3.6 Ω R_DS(on), 2 A I_D, TO-220FP - higher Q_g (12 nC), no body diode t_rr spec, R_thJA = 65 K/W.	Requires heatsink for >0.6 W dissipation; not recommended for surface-mount-only production.	Select only when higher peak current (2 A) is required and through-hole assembly is acceptable.

Compared with STP2NK60Z and FQP2N60, SPN02N60S5 delivers superior efficiency in SMT-based sub-5 W supplies due to its lower R_DS(on), smaller thermal resistance, and guaranteed dv/dt robustness - critical for EMI-sensitive consumer and industrial applications.

FAQ

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

The SPN02N60S5 supports 0.3 A continuous drain current at T_A = 70 °C, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limits imposed by the SOT-223 package's R_thJA of 110 K/W on a 6 cm² PCB copper area, ensuring junction temperature remains ≤150 °C.

Does SPN02N60S5 have avalanche capability?

Yes - SPN02N60S5 is fully avalanche-rated with V_(BR)DS = 700 V (typical) at I_D = 1.8 A, enabling robust operation during inductive switching transients. The datasheet confirms unclamped inductive switching (UIS) capability without external snubbers in properly designed flyback transformers.

Can SPN02N60S5 be used with 5 V gate drive?

No - the gate threshold voltage range is 3.5–5.5 V, but full enhancement requires V_GS ≥ 10 V to achieve rated R_DS(on) = 3 Ω. At 5 V, R_DS(on) increases significantly (>10 Ω), causing excessive conduction loss; a dedicated 10–12 V gate driver or bootstrap circuit is mandatory.

What is the recommended PCB layout for thermal performance?

Mount SPN02N60S5 on a vertical FR4 PCB (1.5 mm thick) with ≥6 cm² copper area connected to Pin 2 (Drain) on one layer (70 µm thickness). Avoid thermal vias under the exposed pad unless filled and capped; maintain ≥1.6 mm clearance from solder mask edges to prevent solder wicking and ensure consistent R_thJA ≤ 110 K/W.
