Product details
Overview
IKZA50N65SS5XKSA1 from Infineon is a CoolSiC™ Hybrid Discrete combining a 650 V, 50 A TRENCHSTOP™ 5 IGBT with a full-rated 6th-generation CoolSiC™ diode in a single PG-TO247-4-3 package. It delivers ultra-low switching losses via Kelvin emitter pin, 1.7 V typical VCE(sat) at 25 °C, and 175 °C max junction temperature-enabling high-efficiency hard-switching industrial SMPS and solar string inverters.
For engineers reviewing the IKZA50N65SS5XKSA1 datasheet, IKZA50N65SS5XKSA1 pinout, IKZA50N65SS5XKSA1 application, or IKZA50N65SS5XKSA1 equivalent, key selection criteria include its four-pin layout (C/E/K/G), 0.55 K/W IGBT Rth(j-c), 1.5 V typical diode VF at 40 A/25 °C, and JEDEC-qualified reliability for UPS and energy storage systems.
Technical Context
This hybrid discrete integrates a silicon IGBT and silicon carbide diode on a shared substrate with isolated thermal paths. The Kelvin emitter (Pin K) enables precise gate control by eliminating source inductance effects, while the 13.0 nH internal emitter inductance is measured 5 mm from case-critical for minimizing voltage overshoot in high-dI/dt switching.
The device operates across -40 to 175 °C junction range and supports 200 A pulsed collector current under 1 µs conditions. Its 10 pF reverse transfer capacitance (Cres) and 110 nC total gate charge enable fast, controllable turn-on/turn-off with low EMI generation in 400 V bus applications.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar hybrid IGBT-diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IKW40N65ES5 | 650 V/40 A Si IGBT + Si diode; no Kelvin emitter; higher VCE(sat) (1.9 V); 150 °C Tvj(max) | Limited to lower-power (<3 kW) or lower-temperature environments due to reduced current and thermal rating | Select when cost sensitivity outweighs efficiency gains and Kelvin sensing is unnecessary |
| FF600R12ME4 | 1200 V/600 A dual IGBT module with integrated Si diodes; larger TO-264 package; no Kelvin emitter | Targeted at medium-voltage motor drives-not suitable for 650 V SMPS or solar where voltage rating and size must match | Choose only for 1200 V systems requiring higher current; not a direct functional substitute |
Compared with IKW40N65ES5, IKZA50N65SS5XKSA1 delivers 12% lower conduction loss and 25% lower switching loss at 400 V, while FF600R12ME4's 1200 V rating and 600 A capacity over-specify for 650 V solar/UPS use-increasing cost and layout complexity without benefit.

FAQ
What is the purpose of the Kelvin emitter (Pin K) in IKZA50N65SS5XKSA1?
The Kelvin emitter provides a dedicated low-inductance path for gate driver feedback, isolating the sensing node from high-current emitter transients. This eliminates voltage spikes caused by source inductance during switching, enabling tighter gate control, reduced overshoot, and improved stability in high-dI/dt applications like solar inverters.
Can IKZA50N65SS5XKSA1 replace standard TO-247 IGBTs without PCB changes?
Yes-it uses the PG-TO247-4-3 package with identical mechanical footprint and M3 mounting screw pattern as standard TO-247 devices. Pin C, E, and G align with conventional layouts; Pin K is added without altering pad dimensions, allowing plug-and-play integration into existing designs.
How does the CoolSiC™ diode improve performance over a standard silicon diode in this hybrid?
The integrated 6th-generation CoolSiC™ diode offers 1.5 V typical forward voltage at 40 A and near-zero reverse recovery charge (Qrr). This cuts freewheeling losses by ~40% and eliminates hard reverse recovery spikes-reducing EMI, snubber requirements, and thermal stress compared to Si diodes in the same package.
What thermal derating applies above 100 °C case temperature?
At Tc = 100 °C, continuous collector current drops to 60.5 A (from 80 A at 25 °C), and power dissipation falls to 137 W (from 274 W). Derating follows linear interpolation per datasheet Fig. "Collector current as a function of case temperature", with full 50 A rating maintained up to Tc ≈ 95 °C under typical heatsink conditions.
