Product details

Overview

SPS04N60C3BKMA1 from Infineon Technologies is a 600 V, 4 A N-channel enhancement-mode power MOSFET in TO-220FP package, featuring R_DS(on) = 1.8 Ω (max) at V_GS = 10 V and T_j = 25 °C, 100% avalanche-rated, and optimized for high-voltage SMPS, PFC stages, and industrial motor drives.

For engineers reviewing the SPS04N60C3BKMA1 datasheet, SPS04N60C3BKMA1 pinout, SPS04N60C3BKMA1 application, or SPS04N60C3BKMA1 equivalent, key selection criteria include its 600 V V_DSS, low gate charge (Q_G = 12 nC), fast switching (t_r = 20 ns), robust dv/dt immunity (15 V/ns), and integrated avalanche energy rating (E_AS = 0.75 mJ).

Technical Context

This MOSFET employs Infineon's CoolMOS™ C3 technology, delivering ultra-low gate charge and improved transconductance (g_fs = 2.5 S typ) to reduce conduction and switching losses simultaneously. Its planar silicon structure supports stable operation up to T_j = 150 °C with guaranteed unclamped inductive switching (UIS) capability.

The device features a fully rated body diode with t_rr = 190 ns and Q_rr = 1.2 µC under specified conditions (I_F = 4 A, V_DD = 400 V), enabling reliable hard-switched half-bridge and LLC resonant converter topologies without external freewheeling diodes.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	600 V - Withstands DC bus voltages up to 400 V in 3-phase rectified systems with margin
R_DS(on) max	1.8 Ω @ V_GS = 10 V, T_j = 25 °C - Enables <1.5 W conduction loss at 4 A continuous drain current
Q_G	12 nC - Reduces gate drive power and enables use with low-current drivers (e.g., 1/2-bridge ICs)
E_AS	0.75 mJ - Supports single-pulse unclamped inductive switching without failure at rated current
t_r/t_f	20 ns / 25 ns - Limits switching transition time in 50–100 kHz SMPS designs to minimize overlap loss
dv/dt immunity	15 V/ns - Prevents spurious turn-on in high-noise bridge-leg configurations
I_D cont	4 A @ T_C = 25 °C - Sustains full load in compact heatsink-limited 30–50 W offline adapters

Pinout & Package

SPS04N60C3BKMA1 is housed in a TO-220FP (full-pack) package with insulated flange, enabling direct mounting to heatsinks without isolation hardware. The package provides 60 K/W thermal resistance from junction-to-case (R_thJC) and supports wave soldering up to 260 °C for 10 s.

Pin/Terminal	Circuit Role	Design Meaning
Drain (Tab)	Main high-side current path	Electrically connected to metal tab; requires thermal interface but no electrical isolation unless mounted on isolated heatsink
Source	Reference node for gate control and current return	Low-inductance connection critical for minimizing gate oscillation and shoot-through risk in half-bridge layouts
Gate	Control terminal for channel modulation	High-impedance input requiring <12 nC charge; sensitive to ESD and ringing-needs RC snubber or gate resistor ≥10 Ω

Key Features

Feature	Design Value
600 V avalanche-rated	Guaranteed single-pulse UIS survival at E_AS = 0.75 mJ, eliminating need for external clamping in flyback/PFC snubbers
Ultra-low gate charge	Q_G = 12 nC enables efficient driving with low-power gate ICs (e.g., IRS2001, UCC27531) without Miller plateau issues
Enhanced dv/dt immunity	Rated 15 V/ns ensures noise immunity in high-dV/dt environments like motor inverter legs and phase-cut dimmers
Optimized body diode	t_rr = 190 ns and soft recovery reduce EMI and commutation losses in synchronous rectification and LLC topologies
Halogen-free construction	Meets IEC 61249-2-21 and RoHS compliance; marked as SPS04N60C3BKMA1 (halogen-free variant)

Applications

AC-DC Power Adapters

Industrial Motor Drives

Use Scenario: 30–60 W universal-input offline flyback converters with active PFC front-end.

IC Role / Device Role / Timing Role: Primary-side switching element handling 400 V DC link voltage and 4 A peak current during PWM on-time.

Use Value: Low R_DS(on) and Q_G reduce total power loss by >15% vs. legacy 600 V MOSFETs, improving efficiency to >88% at full load.

Use Scenario: Low-power 3-phase inverter stage (<1 kW) for HVAC blowers and pump controllers.

IC Role / Device Role / Timing Role: Low-side switch in IGBT/MOSFET half-bridge modules, operating at 8–16 kHz PWM frequency.

Use Value: Robust dv/dt immunity prevents false triggering during high-slew-rate bus transients, increasing system reliability in noisy factory environments.

LED Driver Circuits

UPS & Battery Backup Systems

Use Scenario: High-efficiency constant-current buck LED drivers for street lighting (20–50 W per string).

IC Role / Device Role / Timing Role: Main switching transistor regulating current through high-brightness LED arrays powered from 300–400 V DC bus.

Use Value: Fast t_r/t_f minimizes switching loss at 100 kHz operation, enabling smaller magnetics and higher power density.

Use Scenario: Online double-conversion UPS inverters converting 400 V DC bus to 230 V AC output (500–1000 VA).

IC Role / Device Role / Timing Role: Synchronous rectifier or auxiliary switch in DC-AC H-bridge stage, managing bidirectional energy flow.

Use Value: Fully rated body diode with low Q_rr eliminates need for external Schottky diodes, reducing BOM count and layout area.

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
STP4NK60ZFP	R_DS(on) = 1.8 Ω (same), but Q_G = 16 nC and E_AS not specified; TO-220FP package identical	Lacks guaranteed avalanche rating; unsuitable for unclamped inductive loads without external protection	Select only if avalanche stress is absent and gate drive strength permits higher Q_G
IPP60R190C6	650 V, R_DS(on) = 190 mΩ, Q_G = 22 nC - lower R_DS(on) but higher switching loss and cost	Better conduction efficiency above 2 A, but requires stronger gate driver and careful layout for EMI control	Prefer for high-efficiency 100+ W designs where thermal headroom allows larger heatsink

Compared with STP4NK60ZFP and IPP60R190C6, SPS04N60C3BKMA1 offers optimal balance of ruggedness (guaranteed E_AS), low drive demand (12 nC), and proven field reliability in cost-sensitive 30–60 W industrial power supplies.

FAQ

What is the maximum continuous drain current for SPS04N60C3BKMA1 at 100 °C case temperature?

At T_C = 100 °C, the maximum continuous drain current is 2.5 A, derated from the 4 A rating at 25 °C using the specified thermal resistance and SOA curve. This reflects real-world thermal limits when mounted on a standard 25 cm² heatsink without forced air.

Does SPS04N60C3BKMA1 require a gate resistor, and what value is recommended?

Yes-a gate resistor is mandatory to dampen ringing and limit peak gate current. A value between 10 Ω and 47 Ω is recommended depending on switching speed requirements and driver capability; 22 Ω provides optimal trade-off between rise time (~25 ns) and overshoot suppression in typical 12 V gate drive circuits.

Can SPS04N60C3BKMA1 be used in place of a 500 V MOSFET in an existing design?

Yes, provided layout clearances meet 600 V creepage/clearance standards and gate drive remains compatible. Its higher V_DSS improves margin against voltage spikes in 400 V DC-link applications, but R_DS(on) is higher than many 500 V devices-verify conduction loss impact before substitution.

Is the body diode suitable for synchronous rectification in a buck converter?

No-the body diode is optimized for robustness, not low forward voltage. Its V_SD = 1.4 V at 4 A results in higher conduction loss than discrete Schottky or GaN FETs. Use only in non-critical freewheeling roles or where external diode replacement is impractical.
