Automotive Power Infineon Igbt Module FZ1600R17KF6C_B2 ODM

FZ1600R17KF6C-B2 | Infineon Six-Pack IGBT Module — 1600A / 1700V / 12.5kW / 130×140mm / Industrial Drive Spare

Six-Pack Format at 1600A — One Module, Complete Three-Phase Bridge

The FZ1600R17KF6C-B2 is Infineon's Six-Pack IGBT module at 1600A and 1700V — a complete three-phase inverter bridge in a single housing. All six switching positions of the three-phase bridge are contained within the 130 × 140mm package: upper and lower IGBT with antiparallel freewheeling diode for each of the three output phases (U, V, W).

At 1600A nominal current and 1700V blocking voltage, this is one of the highest-current Six-Pack modules available. The combination of 12.5kW total power dissipation and the FZ EconoPACK+ press-fit housing identifies it as a component for very large-scale drive and energy conversion systems.

Key Specifications

1700V Blocking Voltage — Supporting High-Voltage DC Bus Systems

The 1700V VCES provides the blocking headroom required for drive systems operating from elevated AC supply voltages:

From 690V AC three-phase: Peak line-to-line voltage ≈ 976V DC. The 1700V blocking voltage provides 74% margin above this peak — absorbing supply transients, commutation inductance voltage spikes, and semiconductor body diode reverse recovery overshoots without approaching the IGBT's blocking limit.

From 480V AC systems requiring extended transient protection or operating in supply environments with high transient overvoltage risk: 1700V-class IGBTs provide substantially more headroom than 1200V class for the same supply voltage.

This 1700V capability is why the FZ1600R17KF6C-B2 appears in:

• Large industrial drives fed from 690V AC industrial supply networks
• Wind turbine converter stages operating from high-voltage DC links
• Traction inverters in rail vehicles with elevated DC bus voltages

Applications

Industrial drives: Large variable frequency drives for heavy industry — steel mills, cement plants, mining, and chemical process facilities where motor drives range from hundreds of kilowatts to multi-megawatt.

Wind energy: Generator-side inverter stages in multi-megawatt wind turbines converting variable-speed generator output to stable grid-frequency AC.

Traction: Rail traction inverters for high-speed and heavy freight locomotives — where the combination of high current, high blocking voltage, and compact Six-Pack packaging reduces drive system weight.

Renewable energy storage: Grid-tied battery energy storage system (BESS) inverters at utility scale — converting battery DC to grid AC at high power levels.

Industrial power conversion: Large UPS systems, active front ends for industrial facilities, and high-power DC motor drives in legacy installations.

FAQ

Q1: What is the difference between the 1600A IC,nom and the 2600A IC at TC=25°C specifications?

IC,nom (1600A) is the continuous rated current at the specified case temperature for thermal design purposes — the current the module can sustain indefinitely. IC at TC=25°C (2600A) is the absolute peak DC current with the case held at 25°C — an ideal condition that exceeds the thermal limits of any practical heatsink under sustained operation. In practice, the 1600A figure governs drive design; the 2600A value indicates the module's semiconductor headroom.

Q2: Why does the FZ prefix indicate press-fit terminal technology?

The "FZ" designation in Infineon's IGBT module naming system identifies the EconoPACK+ housing format with press-fit (PressFIT) main power terminals. PressFIT terminals use a spring-loaded contact in the DC bus bar rather than bolted connections — enabling tool-free bus bar disconnection and reconnection for maintenance. The "Z" additionally indicates integrated freewheeling diodes co-packaged with the IGBT chips.

Q3: What gate drive circuit is required for FZ1600R17KF6C-B2 at 1600A?

At 1600A, the IGBT gate capacitance is substantial — the 105nF input capacitance (Cies) and 19µC gate charge require a gate driver capable of providing sufficient current to charge and discharge the gate quickly within the required switching time. A dedicated high-current gate driver module is required — the driver must supply the peak current needed to achieve the desired turn-on and turn-off dV/dt rates within the drive's switching timing requirements.

Q4: What heatsink thermal resistance is required for the FZ1600R17KF6C-B2 at full rated current?

At 1600A and 12.5kW total power dissipation, the module requires a heatsink with very low thermal resistance to keep junction temperature below the 125°C maximum under sustained operation. Forced liquid cooling or high-performance forced-air heatsink systems are standard for modules at this power level. The thermal design must account for the individual IGBT and diode Rth(j-c) values — confirm from the FZ1600R17KF6C-B2 datasheet for the specific per-switch junction-to-case thermal resistance.
