Product details

Overview

SPW20N60S5 from Infineon Technologies is a 600 V, 20 A CoolMOS™ superjunction power MOSFET in PG-TO247 package, featuring R_DS(on) = 0.19 Ω at V_GS = 10 V and T_j = 25 °C, ultra-low gate charge (Q_g = 79–103 nC), and periodic avalanche rating. It serves as a high-efficiency primary-side switch in offline SMPS, PFC stages, and industrial motor drives.

For engineers reviewing the SPW20N60S5 datasheet, SPW20N60S5 pinout, SPW20N60S5 application, or SPW20N60S5 equivalent, key selection criteria include its 20 V/ns dv/dt immunity, 690 mJ single-pulse avalanche energy, 0.6 K/W junction-to-case thermal resistance, and body diode reverse recovery charge (Q_rr = 12 µC) for hard-switched topologies.

Technical Context

This device employs Infineon's 5th-generation CoolMOS™ superjunction technology, enabling reduced conduction and switching losses simultaneously. Its optimized charge distribution yields low C_iss (3000 pF), C_oss (1170 pF), and Cr_ss (28 pF), with energy-related effective output capacitance Co(er) = 83 pF at V_DS = 480 V.

The MOSFET supports robust operation under extreme conditions: rated for repetitive avalanche up to I_AR = 20 A, operates across T_j = −55 °C to +150 °C, and maintains V_(BR)DSS ≥ 600 V down to T_j = 150 °C per characterization curves.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	600 V - Withstands full mains rectified voltage in universal-input 85–265 V_AC SMPS designs.
R_DS(on)	0.19 Ω @ 10 V, 25 °C - Enables low conduction loss in 20 A continuous drain applications.
Q_g	79–103 nC - Reduces gate drive power and enables higher-frequency operation with lower EMI.
E_AS	690 mJ - Supports reliable single-pulse avalanche handling during transient overvoltage events.
dv/dt	20 V/ns - Immune to false turn-on in high-noise, fast-switching bridge configurations.
R_thJC	0.6 K/W - Allows efficient heat transfer to heatsink in TO-247-based power modules.
Q_rr	12 µC - Limits switching loss and voltage overshoot during body diode commutation in LLC or asymmetrical half-bridge.

Pinout & Package

SPW20N60S5 uses the PG-TO247 package (standard 3-pin through-hole variant with isolated tab), optimized for high-power thermal dissipation and mechanical robustness in industrial environments.

Pin/Terminal	Circuit Role	Design Meaning
Drain (Tab)	Main current path from source to load	Electrically connected to metal tab - must be mounted to heatsink with electrically isolating thermal interface.
Source	Reference node for gate control and current return	Low-inductance connection point for gate driver return and current sensing; common reference for PWM control loop.
Gate	Control terminal for channel modulation	High-impedance input requiring low-ESR gate resistor (RG = 3.6 Ω typical) to damp ringing and control dV/dt.

Key Features

Feature	Design Value
Ultra-low gate charge	Q_g = 79–103 nC enables <100 kHz operation with minimal gate drive loss in high-efficiency converters.
Periodic avalanche rated	I_AR = 20 A, t_AR-limited by T_j ≤ 150 °C - supports reliable operation in unclamped inductive switching.
Extreme dv/dt immunity	20 V/ns at V_DS = 480 V, T_j = 125 °C - prevents spurious turn-on in high-side half-bridge configurations.
Low effective output capacitance	Co(er) = 83 pF - reduces turn-off energy loss and improves zero-voltage switching (ZVS) margin in resonant topologies.
Improved transconductance	g_fs = 12 S - delivers stable gain and tight V_GS(th) control (3.5–5.5 V) for predictable turn-on behavior.

Applications

Server PSU Primary Switch

Industrial PFC Boost Stage

Use Scenario: High-density 1U server power supply operating at 100 kHz with active clamp forward or LLC topology.

IC Role / Device Role / Timing Role: Primary-side high-voltage switching element handling 20 A DC input current and 600 V blocking.

Use Value: Low R_DS(on) and Q_g reduce conduction and switching losses, improving efficiency above 95% at full load.

Use Scenario: Three-phase industrial PFC front-end with >3 kW output and forced-air cooling.

IC Role / Device Role / Timing Role: Fast-switching boost switch in continuous conduction mode (CCM) with 50 kHz–100 kHz operation.

Use Value: Low C_oss and Cr_ss minimize voltage-dependent switching loss; avalanche rating ensures reliability during line surges.

Solar Inverter DC-Link Switch

EV Onboard Charger (OBC) Primary Side

Use Scenario: String inverter DC-link stage converting 600–1000 V PV array output to AC grid.

IC Role / Device Role / Timing Role: High-voltage IGBT replacement in two-level or three-level NPC inverter legs.

Use Value: 600 V rating and 20 V/ns dv/dt immunity prevent shoot-through in high-dV/dt grid-synchronization events.

IC Role / Device Role / Timing Role: Primary-side switch managing 3.3–6.6 kW power transfer between AC grid and battery pack.

Use Value: Body diode Q_rr = 12 µC and soft recovery enable ZVS across wide load range without external snubbers.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STW20N60DM2	R_DS(on) = 0.22 Ω, Q_g = 65 nC, no specified avalanche rating	Lacks periodic avalanche capability; requires external clamping in unclamped inductive loads	Prefer when gate drive power minimization is critical and avalanche stress is absent.
IPP60R190C7	R_DS(on) = 0.19 Ω, Q_g = 62 nC, 650 V rating, lower C_oss (750 pF)	Better high-frequency switching but lower V_DS derating margin at 650 V vs. 600 V	Choose for higher-frequency (>150 kHz) designs where voltage margin allows 650 V rating.

Compared with STW20N60DM2 and IPP60R190C7, SPW20N60S5 uniquely combines 600 V rating, 690 mJ avalanche energy, and 20 V/ns dv/dt immunity-making it preferred for ruggedized industrial SMPS and unclamped flyback/PFC where transient robustness is non-negotiable.

FAQ

What is the maximum continuous drain current at 100 °C case temperature?

The SPW20N60S5 supports ID = 13 A continuous drain current at TC = 100 °C, as specified in its Absolute Maximum Ratings table. This derating reflects thermal limits of the PG-TO247 package and ensures safe operation within the 0.6 K/W R_thJC constraint while maintaining T_j ≤ 150 °C under steady-state conditions.

Does SPW20N60S5 have an integrated body diode, and what are its key parameters?

Yes, SPW20N60S5 includes a monolithic body diode with IS = 20 A continuous forward current at TC = 25 °C, V_SD = 1.0–1.2 V, trr = 610 ns, and Q_rr = 12 µC under specified test conditions (VR = 350 V, IF = IS, diF/dt = 100 A/µs). These values are critical for evaluating commutation loss in bridge topologies.

Can SPW20N60S5 replace older CoolMOS™ generations like S3 or S4 in existing designs?

Yes, SPW20N60S5 is a direct drop-in replacement for SPW20N60S3/S4 in most cases due to identical PG-TO247 package, pinout, and voltage/current ratings. However, its lower Q_g and improved dv/dt immunity may require gate resistor adjustment to maintain optimal switching behavior and EMI profile.

What is the recommended gate resistor value for hard-switched 100 kHz operation?

A gate resistor of 3.6 Ω is specified in the datasheet for VDD = 350 V, ID = 20 A testing. For 100 kHz hard-switched operation, 3.3–4.7 Ω is recommended to balance switching speed, gate oscillation damping, and driver power dissipation-verified via oscilloscope measurement of V_GS and V_DS waveforms under actual load.
