Product details

Overview

SPU04N60S5BKMA1 from Infineon Technologies is a 600 V, 4.5 A CoolMOS™ superjunction N-channel power MOSFET in PG-TO251 package, featuring R_DS(on) = 0.95 Ω at V_GS = 10 V and T_j = 25 °C, ultra-low gate charge (Q_g = 17.6–22.9 nC), and periodic avalanche rating. It serves as a high-efficiency primary-side switch in offline SMPS for industrial AC/DC adapters and LED drivers.

For engineers reviewing the SPU04N60S5BKMA1 datasheet, SPU04N60S5BKMA1 pinout, SPU04N60S5BKMA1 application, or SPU04N60S5BKMA1 equivalent, key selection criteria include its 20 V/ns dv/dt immunity, E_AS = 130 mJ single-pulse avalanche energy, C_iss = 580 pF, and thermal resistance R_thJC = 2.5 K/W - critical for high-reliability flyback and PFC stage design.

Technical Context

This device implements Infineon's 5th-generation CoolMOS™ superjunction architecture optimized for hard-switched 600 V applications. Its low effective output capacitance (C_o(er) = 20 pF) and reduced gate-to-drain charge (Q_gd = 11 nC) minimize switching losses during turn-off transitions in continuous conduction mode (CCM) PFC and quasi-resonant flyback converters.

The MOSFET supports robust operation under repetitive avalanche stress (I_AR = 4.5 A, E_AR = 0.4 mJ) and features a body diode with t_rr = 900–1530 ns and Q_rr = 3.2 µC, enabling reliable operation in discontinuous conduction mode (DCM) without external snubbers.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	600 V - rated for universal-input offline SMPS up to 380 V DC bus with margin
R_DS(on)	0.95 Ω max @ 10 V, 25 °C - enables <4.5 W conduction loss at 4.5 A in TO251
Q_g	17.6–22.9 nC - reduces gate drive power and allows use of smaller gate drivers
E_AS	130 mJ - supports single-pulse inductive load switching without failure
C_iss	580 pF - lowers Miller effect and improves noise immunity in high-dv/dt environments
dv/dt Rating	20 V/ns - ensures stable operation in fast-switching topologies without spurious turn-on
R_thJC	2.5 K/W - enables 50 W dissipation with modest heatsinking at T_C = 25 °C

Pinout & Package

SPU04N60S5BKMA1 uses the PG-TO251 (IPAK) surface-mount package with 3 terminals: Drain (pin 1), Gate (pin 2), Source (pin 3). The drain tab is electrically connected to pin 1 and thermally coupled to PCB copper for enhanced heat transfer.

Pin/Terminal	Circuit Role	Design Meaning
1 (Drain)	Main current path from drain to source	Connected to high-voltage DC bus; requires isolation clearance ≥2.5 mm
2 (Gate)	Control electrode for channel formation	High-impedance input requiring low-inductance gate loop to suppress oscillation
3 (Source)	Reference node for gate drive and current sensing	Common return for gate driver and sense resistor; must be low-impedance ground plane

Key Features

Feature	Design Value
Ultra-low gate charge	Q_g ≤ 22.9 nC reduces gate driver power loss and enables higher switching frequencies
Periodic avalanche rated	I_AR = 4.5 A, E_AR = 0.4 mJ supports repetitive inductive switching without derating
Extreme dv/dt immunity	20 V/ns rating prevents false turn-on in noisy high-side configurations
Low effective output capacitance	C_o(er) = 20 pF minimizes stored energy loss during hard-switched turn-off
Improved transconductance	g_fs typ = 2.5 S enhances linearity and current control accuracy in analog feedback loops

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
IPP60R099C6	650 V, R_DS(on) = 0.099 Ω, Q_g = 32 nC, TO220 package	Higher conduction efficiency but larger footprint and higher gate drive demand	Preferred for higher-power (>150 W), lower-frequency (<65 kHz) designs where thermal mass matters more than size
SPW20N60C3	600 V, R_DS(on) = 0.19 Ω, Q_g = 42 nC, TO247 package	Lower R_DS(on) but significantly higher switching losses and larger board area	Suitable when maximum efficiency at light loads is prioritized over compact layout and fast transient response

Compared with IPP60R099C6 and SPW20N60C3, SPU04N60S5BKMA1 delivers optimal balance of low gate charge, compact PG-TO251 footprint, and proven avalanche ruggedness - making it ideal for space-constrained, medium-power industrial SMPS where reliability under transient stress is non-negotiable.

FAQ

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

The maximum continuous drain current for SPU04N60S5BKMA1 is 2.8 A at T_C = 100 °C, as specified in the Absolute Maximum Ratings table. This value accounts for thermal derating due to junction-to-case thermal resistance (2.5 K/W) and safe operating area limitations under sustained conduction.

Does this MOSFET require a negative gate voltage to prevent spurious turn-on?

No. SPU04N60S5BKMA1 has a guaranteed dv/dt immunity of 20 V/ns at V_DS = 480 V and T_j = 125 °C, eliminating the need for negative gate drive in typical high-side flyback or PFC applications. Its gate threshold voltage (3.5–5.5 V) and low Crss also suppress Miller-induced turn-on.

Can the integrated body diode be used for synchronous rectification?

No. The body diode is not optimized for synchronous rectification: its reverse recovery time (900–1530 ns) and Q_rr (3.2 µC) are too high for efficient high-frequency SR operation. External Schottky or GaN FETs are recommended for secondary-side rectification above 100 kHz.

What is the recommended PCB layout for thermal performance?

For optimal thermal performance, use a minimum 6 cm² copper pour on the drain pad (pin 1) connected to an internal ground plane via ≥6 thermal vias (0.3 mm diameter, 0.8 mm pitch). Maintain ≥2.5 mm creepage/clearance to adjacent traces, and avoid routing signal traces under the MOSFET body per Infineon's layout guidelines for PG-TO251.
