Infineon Technologies IGQ100N120S7XKSA1

Overview

IGQ100N120S7XKSA1 from Infineon is a 1200 V, 100 A short-circuit rugged TRENCHSTOP™ IGBT 7 designed for high-voltage switching in industrial power converters and solar inverters. It delivers V_CE(sat) = 2.0 V at T_vj = 175 °C, 8 µs short-circuit withstand time, and optimized dv/dt controllability for robust gate drive design in hard-switched topologies.

For engineers reviewing the IGQ100N120S7XKSA1 datasheet, IGQ100N120S7XKSA1 pinout, IGQ100N120S7XKSA1 application, or IGQ100N120S7XKSA1 equivalent, key selection criteria include junction-temperature-dependent saturation voltage, short-circuit ruggedness under 600 V bus conditions, thermal resistance (R_th(j–c) = 0.13–0.18 K/W), and gate charge (Q_G = 610 nC) for loss budgeting in 10–20 kHz PWM systems.

Technical Context

This IGBT employs TRENCHSTOP™ 7 silicon technology with field-stop trench gate structure to achieve low conduction loss and controlled turn-off tail current. Its 8 µs short-circuit capability is validated at V_CC ≤ 600 V, V_GE = 15 V, and T_vj = 150 °C, enabling reliable operation without active desaturation protection in many industrial designs.

The device features low output capacitance (C_oes = 270 pF) and reverse transfer capacitance (C_res = 60 pF) at 25 V, supporting stable high-speed switching up to 20 kHz with minimal Miller-induced shoot-through risk. Gate threshold voltage (V_GE(th) = 5.1–6.5 V) ensures noise immunity while maintaining sufficient drive margin for ±15 V gate drivers.

FAQ

What is the maximum allowable gate-emitter voltage for IGQ100N120S7XKSA1?

The absolute maximum gate-emitter voltage is ±20 V DC, with transient rating of ±25 V for pulses ≤0.5 µs. Exceeding ±20 V continuously risks oxide degradation and threshold shift. Recommended gate drive is +15 V / –8 V to ensure robust turn-on and fast, low-loss turn-off while avoiding Miller-induced false triggering.

Does IGQ100N120S7XKSA1 include an integrated anti-parallel diode?

No, IGQ100N120S7XKSA1 is a standalone IGBT. Infineon specifies the companion diode IKQ100N120CS7 for use in complementary half-bridge configurations. The diode shares identical package (PG-TO247-3-PLUS) and thermal characteristics, enabling matched thermal cycling and simplified heatsink design.

How is short-circuit ruggedness tested for this IGBT?

Short-circuit withstand time is measured per JEDEC JESD22-A109 with V_CC ≤ 600 V, V_GE = 15 V, T_vj = 150 °C, and ≤1000 total events. Each event is limited to 8 µs, with ≥1.0 s recovery between tests. This validates safe operation under bus fault conditions typical in industrial motor drives and UPS systems.

Can IGQ100N120S7XKSA1 be used in parallel configurations?

Yes-its positive V_CE(sat) temperature coefficient (2.0 V at 175 °C vs. 1.65 V at 25 °C) enables inherent current sharing. Successful paralleling requires matched gate drive impedance (<±5% variation), symmetrical PCB layout, and Kelvin emitter connections to eliminate common-source inductance imbalance.
