Product details

Overview

SKW07N120 from Infineon is a 1200 V, 8 A NPT-technology IGBT with integrated soft-fast anti-parallel emitter-controlled diode, optimized for motor controls, inverters, and SMPS. It delivers 0.7 mJ turn-off energy at T_j = 25 °C, 10 µs short-circuit withstand time at V_GE = 15 V, and 1 K/W junction-to-case thermal resistance in PG-TO-247-3 package.

For engineers reviewing the SKW07N120 datasheet, SKW07N120 pinout, SKW07N120 application, or SKW07N120 equivalent, this device is selected for high-voltage switching where ruggedness, tight parameter distribution, and parallel-switching capability are required - especially in industrial motor drives operating up to 150 °C junction temperature.

Technical Context

This IGBT uses Non-Punch-Through (NPT) silicon technology, enabling high ruggedness, temperature-stable V_CE(sat) (2.5–4.3 V across –40 °C to 150 °C), and consistent dynamic performance under repeated short-circuit stress (≤1000 events, >1 s interval). Its integrated emitter-controlled diode provides soft reverse recovery with t_rr = 60 ns (T_j = 25 °C) and Q_rr = 0.3 µC.

The device supports gate drive with ±20 V rating and exhibits low input capacitance (C_iss = 720–870 pF) and moderate gate charge (Q_gate = 70–90 nC), enabling efficient 10–100 kHz switching in hard-switched topologies. Thermal design is facilitated by separate IGBT and diode R_thJC values (1.0 K/W and 2.5 K/W respectively).

Key Specifications

Parameter	Value and Actual Design Meaning
V_CE	1200 V - Maximum blocking voltage for use in 1000 V DC bus systems with margin.
I_C	8 A continuous - Rated collector current at T_C = 100 °C; supports 16.5 A pulsed operation.
E_off	0.7 mJ at T_j = 25 °C - Enables lower switching losses in high-frequency inverter stages.
t_SC	10 µs - Short-circuit withstand capability at V_GE = 15 V, critical for fault-tolerant motor control designs.
R_thJC (IGBT)	1.0 K/W - Low thermal resistance enables high-power density mounting on heatsinks.
V_F (diode)	2.0 V at I_F = 7 A, T_j = 25 °C - Forward voltage of integrated anti-parallel diode impacts conduction loss in freewheeling paths.
Q_gate	70–90 nC - Gate charge determines required driver peak current and influences switching speed control.

Pinout & Package

SKW07N120 is housed in PG-TO-247-3 package - a through-hole, single-island power package with 3 terminals and industry-standard mechanical footprint. The case is electrically connected to the collector.

Pin/Terminal	Circuit Role	Design Meaning
Collector (C)	Main high-side power terminal	Connected to DC bus positive; carries full load current and must be thermally coupled to heatsink via case.
Gate (G)	Control input	Receives ±20 V gate drive; requires low-inductance layout due to 70–90 nC charge and fast switching transitions.
Emitter (E)	Power return and reference node	Serves as common reference for both IGBT and integrated diode; carries bidirectional current in bridge configurations.

Key Features

Feature	Design Value
NPT silicon technology	Delivers tight parameter distribution and stable V_CE(sat) over temperature - essential for parallel IGBT operation without current imbalance.
Integrated emitter-controlled diode	Provides soft, fast recovery (t_rr ≤ 170 ns at T_j = 150 °C) reducing EMI and diode-induced voltage spikes in inductive loads.
10 µs short-circuit rating	Enables robust protection schemes in motor drives without requiring ultra-fast desaturation detection circuitry.
JEDEC1-qualified	Validated for industrial motor control and SMPS applications per reliability and stress-test standards.
Pb-free and RoHS-compliant plating	Meets environmental compliance requirements for global OEM production without lead-based solder compatibility concerns.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
IXYS IXGN75N120B3	Higher I_C (75 A), higher E_off (1.2 mJ), TO-247-4L package with Kelvin emitter.	Better suited for high-current parallel designs; requires Kelvin connection for optimal gate control.	Select when system needs >15 A average current and gate drive stability under high di/dt is critical.
STMicroelectronics STGW40H120DF2	Lower V_CE (1200 V), same I_C (8 A), but higher V_F (2.4 V) and longer t_rr (120 ns).	Less suitable for high-frequency SMPS due to higher diode losses and slower recovery.	Prefer only if cost sensitivity outweighs efficiency targets and thermal budget permits higher conduction loss.

Compared with IXGN75N120B3 and STGW40H120DF2, SKW07N120 offers the best balance of low E_off, soft diode recovery, and proven ruggedness in motor control - making it ideal for space-constrained, thermally demanding 3–7.5 kW industrial inverters.

FAQ

What is the maximum gate-emitter voltage rating for SKW07N120?

The absolute maximum gate-emitter voltage is ±20 V DC, with recommended operating range of –10 V to +15 V. Exceeding ±20 V risks permanent gate oxide damage. Gate drive circuits must include clamping or active regulation to prevent overshoot during fast switching transitions or inductive coupling.

Does SKW07N120 require an external freewheeling diode?

No - SKW07N120 integrates a soft, fast-recovery emitter-controlled diode in the same package. This anti-parallel diode is rated for 13 A DC at T_C = 25 °C and supports bidirectional current flow in bridge configurations without external components.

How does junction temperature affect V_CE(sat) performance?

V_CE(sat) increases with junction temperature: from 2.5 V at T_j = 25 °C to 3.6 V at T_j = 150 °C (I_C = 8 A, V_GE = 15 V). This positive temperature coefficient supports inherent current sharing in parallel configurations and improves thermal stability.

Can SKW07N120 be used in parallel with identical units?

Yes - its NPT structure provides a positive V_CE(sat) temperature coefficient and tight parameter distribution, enabling stable current sharing. Successful parallel operation requires matched gate drive impedance, symmetrical PCB layout, and shared heatsinking to minimize thermal gradients between devices.
