Product details

Overview

SPB03N60C3ATMA1 from Infineon Technologies is a 600 V, 3.3 A N-channel CoolMOS™ C3 power MOSFET in TO-220FP package, featuring R_DS(on) = 1.4 Ω (typ @ T_j = 25°C), ultra-low gate charge (Q_g = 12 nC), and 100% avalanche-rated operation; used as a high-voltage switching device in offline SMPS primary-side switches and PFC circuits.

For engineers reviewing the SPB03N60C3ATMA1 datasheet, SPB03N60C3ATMA1 pinout, SPB03N60C3ATMA1 application, or SPB03N60C3ATMA1 equivalent, key selection criteria include its 600 V V_DSS, 1.4 Ω R_DS(on), 12 nC total gate charge, 100% unclamped inductive switching capability, and thermal resistance R_thJC = 2.5 K/W - all critical for high-efficiency, compact AC/DC adapter and industrial power supply designs.

Technical Context

This MOSFET employs Infineon's 3rd-generation CoolMOS™ superjunction technology, enabling high voltage blocking with reduced specific on-resistance and optimized charge profile. Its gate threshold voltage (V_GS(th) = 2.5–4.5 V) supports standard 10 V gate drive, while the low Q_gd/Q_gs ratio improves hard-switching robustness.

The device is fully characterized for repetitive avalanche energy (E_AR = 79 mJ @ V_DD = 400 V) and features fast body diode recovery (t_rr = 180 ns, Q_rr = 0.52 µC), making it suitable for continuous conduction mode (CCM) PFC and resonant LLC topologies where diode commutation stress is critical.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	600 V - supports universal input (85–265 VAC) offline converters with sufficient margin against line surges and ringing.
R_DS(on) max	1.7 Ω @ T_j = 100°C - enables low conduction loss in 30–60 W SMPS primary switches at full load.
Q_g	12 nC @ V_GS = 0–10 V - reduces gate driver power loss and allows use of low-cost, low-current drivers in cost-sensitive adapters.
E_AS	520 mJ - rated for single-pulse unclamped inductive switching, supporting reliable operation without external snubbers in flyback designs.
t_r/t_f	12/22 ns @ I_D = 1.5 A - enables high-frequency switching (>100 kHz) with minimal overlap loss in quasi-resonant controllers.
R_thJC	2.5 K/W - allows 3.3 A continuous current with ≤50 K temperature rise over case when mounted on ≥10 cm² copper area.

Pinout & Package

SPB03N60C3ATMA1 is housed in a TO-220FP (Full-Pak) package with insulated flange, offering creepage/clearance compliance for reinforced insulation in Class II systems. The drain is connected to the flange for direct heatsinking; source and gate are on leads.

Pin/Terminal	Circuit Role	Design Meaning
Drain (Flange)	High-voltage power output node	Electrically connected to metal flange; must be isolated from chassis unless system ground reference permits.
Source	Power return and gate reference	Serves as common reference for gate drive; requires low-inductance layout to minimize dV/dt coupling during switching.
Gate	Control terminal	High-impedance input requiring <12 nC charge for full enhancement; sensitive to ESD and requires series gate resistor (≥10 Ω) for oscillation damping.

Key Features

Feature	Design Value
Ultra-low gate charge	Q_g = 12 nC enables efficient 65–130 kHz operation with minimal driver loss in compact adapters.
100% avalanche-rated	Guaranteed single-pulse E_AS = 520 mJ ensures reliability under transient overloads without derating.
Optimized body diode	t_rr = 180 ns and Q_rr = 0.52 µC reduce commutation loss and EMI in CCM PFC stages.
Thermally enhanced TO-220FP	Insulated flange supports safe mounting on heatsinks without additional isolation pads in double-insulated designs.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STP3NK60ZFP	R_DS(on) = 2.2 Ω (max), Q_g = 14 nC, no specified E_AS rating	Lacks guaranteed avalanche ruggedness; less suitable for unclamped inductive loads	Prefer SPB03N60C3ATMA1 where surge immunity and snubberless operation are required.
IPP60R190C6	R_DS(on) = 0.19 Ω, Q_g = 22 nC, 650 V rating, higher current (6.5 A)	Higher conduction efficiency but larger gate drive demand; over-specified for ≤3.3 A applications	Choose SPB03N60C3ATMA1 for cost-optimized 3–4 A designs where gate drive simplicity and thermal footprint matter.

Compared with STP3NK60ZFP and IPP60R190C6, SPB03N60C3ATMA1 delivers optimal balance of avalanche ruggedness, gate drive efficiency, and thermal performance in sub-4 A, 600 V primary-side switching - avoiding both under-ruggedness and unnecessary gate drive overhead.

FAQ

Is SPB03N60C3ATMA1 suitable for hard-switched PFC applications?

Yes - its 600 V V_DSS, 1.4 Ω R_DS(on) (typ), and 180 ns body diode t_rr make it appropriate for continuous conduction mode (CCM) PFC stages up to 100 kHz. The low Q_gd/Q_gs ratio also improves voltage-dependent switching behavior under high dv/dt conditions typical in boost converters.

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

The datasheet specifies I_D = 3.3 A at T_C = 100°C. This rating assumes proper PCB copper area (≥10 cm²) and mounting to an adequately sized heatsink. Derating is not required below this temperature, but ambient airflow or thermal interface quality directly impacts achievable current.

Does SPB03N60C3ATMA1 require a negative gate turn-off voltage?

No - its gate threshold voltage (2.5–4.5 V) and positive-only gate drive specification mean it operates reliably with 0 V to +10 V or +12 V gate drive. A negative turn-off voltage is unnecessary and not recommended, as the device lacks negative V_GS rating beyond –20 V.

Can SPB03N60C3ATMA1 replace older CoolMOS™ C2 devices in existing designs?

Yes - it is a direct drop-in replacement for SPB03N60C2ATMA1, offering identical pinout, voltage rating, and thermal footprint, plus improved R_DS(on) (1.4 Ω vs. 1.6 Ω typ) and lower Q_g (12 nC vs. 14 nC). No layout or drive circuit changes are needed for migration.
