Product details

Overview

IDW100E60FKSA1 from Infineon Technologies is a 600 V, 100 A fast-switching emitter-controlled diode in PG-TO247-3 package, designed for high-efficiency power conversion in industrial inverters and welding equipment. It delivers 1.65 V forward voltage at 100 A and 25°C, 120 ns reverse recovery time at 25°C, 3.6 µC reverse recovery charge, and operates up to 175°C junction temperature.

For engineers reviewing the IDW100E60FKSA1 datasheet, IDW100E60FKSA1 pinout, IDW100E60FKSA1 application, or IDW100E60FKSA1 equivalent, key selection criteria include soft switching behavior, low Q_rr, thermal robustness at 175°C, and compatibility with parallel operation in high-current motor drive DC-link circuits.

Technical Context

This emitter-controlled diode uses Infineon's proprietary Emitter Controlled (EC) technology to achieve fast, soft reverse recovery with minimal tail current-enabling reduced switching losses and EMI in hard-switched IGBT-based inverters. Its low dI_rr/dt (750 A/µs at 25°C) and controlled Irr (49.5 A peak) support stable commutation in high-dI/dt environments.

The device features a thermally optimized PG-TO247-3 package with 0.40 K/W junction-to-case thermal resistance, enabling high-power dissipation (375 W at T_C = 25°C) while maintaining safe junction temperatures under sustained 100 A conduction and repetitive surge conditions (400 A, 10 ms).

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	600 V - blocks full DC-link voltage in 400–600 V industrial inverters without derating
I_F (continuous)	100 A @ T_C = 100°C - supports sustained output current in motor drives and welders
V_F	1.65 V @ 100 A, 25°C - reduces conduction loss by ~15% vs. standard FREDs at same rating
t_rr	120 ns @ 25°C, 400 V, 100 A, dI_F/dt = 1200 A/µs - enables >20 kHz switching with low turn-off loss
Q_rr	3.6 µC @ 25°C - minimizes energy dissipated during IGBT turn-on in bridge legs
T_j,max	175°C - allows compact heatsink design and extended overload capability in sealed enclosures
R_thJC	0.40 K/W - enables direct thermal coupling to heatsinks for high-power density layouts

Applications

Industrial Motor Drives

Resistance Welding Equipment

Use Scenario: Three-phase inverter stage in 75–150 kW AC servo drives operating at 8–16 kHz PWM frequency.

IC Role / Device Role / Timing Role: Freewheeling diode in IGBT half-bridge leg, providing low-loss commutation path during dead-time and regeneration.

Use Value: 120 ns t_rr and soft recovery reduce voltage overshoot across IGBTs, lowering snubber requirements and improving system efficiency by 0.8–1.2%.

Use Scenario: Primary-side rectification and freewheeling in medium-frequency (1–4 kHz) inverter-based spot welders with 50–100 kA secondary current pulses.

IC Role / Device Role / Timing Role: High-current DC-link diode handling repetitive 400 A surge currents and rapid polarity reversal during weld cycles.

Use Value: 400 A non-repetitive surge rating and 175°C T_j,max ensure reliability under extreme thermal cycling and short-circuit stress.

UPS Systems

Induction Heating Inverters

Use Scenario: Bidirectional DC-link clamping in online double-conversion UPS with active PFC and IGBT output stage.

IC Role / Device Role / Timing Role: Clamping diode absorbing reactive energy during line transients and battery-mode transitions.

Use Value: Low reverse leakage (<40 µA at 25°C) prevents standby power loss; soft recovery avoids false triggering of overvoltage protection.

Use Scenario: Resonant tank freewheeling in 20–50 kW solid-state induction heating systems operating at 10–50 kHz.

IC Role / Device Role / Timing Role: High-frequency freewheeling diode in series-resonant inverter leg, conducting high di/dt currents with minimal ringing.

Use Value: Controlled dI_rr/dt (750 A/µs) and low Q_rr suppress parasitic oscillation, improving coil coupling efficiency and reducing EMI filter size.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-voltage, high-current freewheeling diode applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IXYS MDD100-16N1	1600 V V_RRM, 100 A I_F, 2.1 V V_F, 250 ns t_rr - higher voltage rating but slower and higher loss	Suitable for 1200 V DC-link systems; less efficient in 600 V welders due to higher conduction and switching loss	Select when higher blocking voltage is required and thermal margin permits higher V_F penalty
STMicroelectronics STTH100L06TV1	600 V V_RRM, 100 A I_F, 1.85 V V_F, 180 ns t_rr, no EC technology - higher Q_rr (6.2 µC)	Acceptable in lower-frequency (<10 kHz) motor drives; not recommended for high-dI/dt welding or resonant heating	Choose only if cost is primary constraint and soft recovery is not critical to system EMI or efficiency targets

Compared with MDD100-16N1 and STTH100L06TV1, IDW100E60FKSA1 provides superior soft switching, lowest Q_rr, and highest thermal capability-making it optimal for high-efficiency, high-reliability 600 V industrial inverters where switching loss and thermal management are design-critical.

FAQ

What is the maximum continuous forward current at 100°C case temperature?

The IDW100E60FKSA1 supports 96 A continuous forward current at T_C = 100°C, as specified in its Absolute Maximum Ratings table. This value reflects thermal derating due to reduced heat transfer efficiency at elevated case temperatures and ensures safe operation within the 175°C maximum junction limit under steady-state conduction.

Does this diode require a gate resistor or external control signal?

No. The IDW100E60FKSA1 is a two-terminal uncontrolled power diode with no gate terminal or control interface. It operates solely based on forward bias voltage polarity and current direction, functioning as a passive freewheeling or clamping element in converter topologies without any drive circuitry.

Can IDW100E60FKSA1 be paralleled with identical units without external balancing components?

Yes. Its matched dynamic parameters (t_rr, Q_rr, V_F) and low thermal resistance (0.40 K/W) enable stable current sharing across parallel units under both static and transient conditions, eliminating the need for series gate resistors or current-sharing inductors in properly laid-out PCBs with symmetrical thermal paths.

What is the reverse recovery charge at 175°C junction temperature?

At T_j = 175°C, VR = 400 V, IF = 100 A, and dI_F/dt = 1200 A/µs, the reverse recovery charge Q_rrm is 7.8 µC. This value is 117% higher than the 25°C value (3.6 µC), reflecting increased minority carrier lifetime at elevated temperature-a critical parameter for loss calculation in high-temperature operation.
