Product details

Overview

SKB02N120ATMA1 from Infineon is a 1200 V, 2 A NPT-technology IGBT with integrated soft-fast anti-parallel emitter-controlled diode, rated for 10 µs short-circuit withstand time at Tj ≤ 150 °C and optimized for motor control in washing machines, fans, pumps, and vacuum cleaners.

For engineers reviewing the SKB02N120ATMA1 datasheet, SKB02N120ATMA1 pinout, SKB02N120ATMA1 application, or SKB02N120ATMA1 equivalent, this device delivers low Eoff (0.06–0.15 mJ), tight parameter distribution, parallel-switching capability, and JEDEC1-qualified ruggedness for high-reliability inverter designs.

Technical Context

This IGBT employs Non-Punch-Through (NPT) silicon technology to achieve temperature-stable VCE(sat) (2.5–4.3 V), high ruggedness, and uniform dynamic behavior across production lots. Its integrated emitter-controlled diode provides soft reverse recovery (trr ≤ 90 ns at 150 °C) and low Qrr (0.10–0.30 µC), reducing switching losses and EMI in hard-switched topologies.

The device operates with ±20 V gate drive, supports 150 °C junction temperature, and features a defined short-circuit safe operating area (10 µs at VGE = 15 V). Thermal resistance from junction-to-case is 2.0 K/W for the IGBT and 4.5 K/W for the diode, enabling efficient heatsink coupling in compact inverters.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CE	1200 V - Withstands DC bus voltages up to 1200 V in industrial and appliance inverters.
I_C (T_C = 100 °C)	2.8 A - Continuous current rating suitable for 300–500 W motor drives at elevated case temperatures.
E_off	0.06–0.15 mJ - Low turn-off loss enables higher switching frequencies without excessive thermal stress.
t_SC	10 µs - Defined short-circuit withstand time allows robust overcurrent protection design with fixed blanking intervals.
V_F (I_F = 2 A)	1.75–2.5 V - Low forward voltage of integrated diode reduces conduction loss during freewheeling.
R_thJC (IGBT)	2.0 K/W - Enables direct mounting to heatsinks with predictable thermal performance in sealed enclosures.
Q_g	11 nC - Moderate gate charge supports standard 15 V gate drivers with <100 Ω series resistance.

Pinout & Package

SKB02N120ATMA1 is housed in PG-TO-263-3-2 (D²PAK) surface-mount package with G–C–E terminal arrangement and exposed drain pad for thermal enhancement.

Equivalent & Alternatives

The following parts are listed as comparable options for similar IGBT-inverter applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IKP20N120T	Higher I_C (20 A), TO-220 package, 1200 V, but no integrated diode	Requires external fast diode; suited for higher-power (>1 kW) inverters with discrete layout	Select when system-level thermal management permits larger package and discrete diode integration.
FGA25N120ANTD	1200 V, 25 A, TO-3P, field-stop IGBT with ultra-low E_off (0.045 mJ), no integrated diode	Targeted at industrial UPS and solar inverters; lacks soft-recovery diode for low-noise appliance use	Prefer for high-efficiency, high-power systems where diode selection is independent and EMI filtering is less constrained.

Compared with IKP20N120T and FGA25N120ANTD, SKB02N120ATMA1 uniquely integrates a soft-recovery diode in a compact D²PAK package, delivering lower system-level EMI and simplified BOM for sub-500 W appliance inverters-without requiring external diode layout or thermal derating compromises.

FAQ

What is the maximum recommended gate resistor value for SKB02N120ATMA1 in a 20 kHz washing machine inverter?

A 91 Ω gate resistor is specified in the datasheet for 2 A, 800 V inductive switching at 150 °C. For 20 kHz operation, values between 47 Ω and 100 Ω balance switching loss and EMI; exceeding 120 Ω increases turn-off time beyond safe margins for short-circuit protection.

Does SKB02N120ATMA1 require an external freewheeling diode?

No. It integrates a soft, fast-recovery emitter-controlled diode rated for 4.5 A DC at 25 °C and 2 A at 100 °C. This eliminates the need for an external diode in standard inverter half-bridge configurations, reducing PCB area and parasitic inductance.

Can SKB02N120ATMA1 be paralleled with identical units?

Yes. Its NPT technology ensures tight V_CE(sat) distribution and positive temperature coefficient above 100 °C, enabling stable current sharing without emitter resistors-validated in Infineon's application note AN2015-04 for multi-leg inverter modules.

What is the minimum gate-emitter voltage required to fully saturate SKB02N120ATMA1 at 150 °C?

V_GE(th) ranges from 3.0 V to 5.0 V at 25 °C and decreases slightly with temperature. To ensure full saturation at 150 °C, apply ≥15 V gate drive-verified by V_CE(sat) ≤ 3.7 V at I_C = 2 A and T_j = 150 °C in the datasheet's Figure 8.
