Product details

Overview

IDW75E60FKSA1 from Infineon Technologies is a 600 V, 75 A fast-switching emitter-controlled diode (EmCon) optimized for high-efficiency motor drives and industrial welding inverters. It delivers 1.65 V forward voltage at 75 A and 25°C, 121 ns reverse recovery time at 25°C, 2.4 µC reverse recovery charge, and operates up to 175°C junction temperature in PG-TO247-3 package.

For engineers reviewing the IDW75E60FKSA1 datasheet, IDW75E60FKSA1 pinout, IDW75E60FKSA1 application, or IDW75E60FKSA1 equivalent, key selection criteria include soft-switching capability, low Q_rr under high dI_F/dt (1460 A/µs), thermal robustness at 175°C, and paralleling suitability for high-current DC-link rectification.

Technical Context

This EmCon diode uses Infineon's proprietary emitter-controlled structure to reduce minority carrier lifetime without lifetime-killing dopants, enabling simultaneous low V_F and fast, soft recovery. Its dynamic behavior is characterized by controlled dI_rr/dt (921–1013 A/µs) and low peak I_rr (38.5–56.2 A) across –40°C to 175°C.

The device is rated for repetitive 600 V blocking and 75 A continuous forward current at T_C = 100°C, with 220 A surge rating (10 ms sine half-wave) and 0.5 K/W junction-to-case thermal resistance - enabling high-power density designs in forced-air or liquid-cooled motor drive inverters.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	600 V - supports 400 V AC input rectification with 50% safety margin in 3-phase industrial drives
I_F (continuous)	75 A at T_C = 100°C - enables compact heatsink design in 30–50 kW motor inverters
V_F	1.65 V at 75 A, 25°C - reduces conduction loss by ~15% vs. standard ultrafast diodes
t_rr	121 ns at 25°C, 400 V, 75 A, dI_F/dt = 1460 A/µs - minimizes switching loss in 10–20 kHz IGBT-based inverters
Q_rr	2.4 µC at 25°C - lowers EMI generation and snubber stress during turn-off
T_j,max	175°C - allows operation in high-ambient environments (e.g., enclosed welders, traction converters)
R_thJC	0.5 K/W - supports >200 W power dissipation with moderate case cooling (T_C ≤ 90°C)

Pinout & Package

Supplied in PG-TO247-3 package: isolated mounting base, single-drain tab, three-terminal through-hole outline with 2.54 mm lead pitch. Case material is epoxy-molded thermoset with tin-plated copper leads (RoHS-compliant, Pb-free).

Pin/Terminal	Circuit Role	Design Meaning
Anode (A)	High-side current entry point	Connected to DC-link positive in boost PFC or inverter leg; rated for 220 A surge
Cathode (K)	Low-side current exit point	Directly bonded to heatsink via isolated tab; carries full load current and dissipates heat
Case / Tab	Thermal and electrical reference	Electrically connected to cathode; must be mounted on insulated heatsink to avoid short-circuit

Key Features

Feature	Design Value
EmCon technology	Enables 1.65 V V_F + 121 ns t_rr trade-off unattainable with conventional PiN or Schottky structures
Soft switching behavior	Controlled dI_rr/dt (≤1013 A/µs) reduces voltage overshoot and EMI filter burden
Easy paralleling	Positive V_F temperature coefficient ensures current sharing without external ballasting resistors
175°C operation	Extends usable life in sealed enclosures where ambient exceeds 85°C (e.g., robotic welders)
Pb-free RoHS compliance	Meets IPC-J-STD-020 moisture sensitivity level 1 (MSL1); compatible with lead-free reflow profiles

Applications

Industrial Motor Drives

Resistance Welding Inverters

Use Scenario: Three-phase IGBT inverter feeding 30–60 kW induction or PMSM motors in CNC machines and conveyors.

IC Role / Device Role / Timing Role: Freewheeling diode in inverter leg; clamps inductive kickback during IGBT turn-off.

IC Role / Device Role / Timing Role: Output rectifier converting high-frequency AC to DC for electrode current delivery.

Use Value: Soft recovery (121 ns t_rr, 38.5 A I_rr) prevents transformer saturation and reduces RFI emissions below CISPR-11 Class A limits.

Solar Central Inverters

UPS Rectifier Stages

Use Scenario: Boost-stage freewheeling diode in 500 kW central PV inverters operating at 15–25 kHz switching frequency.

IC Role / Device Role / Timing Role: High-current path during MOSFET/IGBT conduction phase; handles 75 A average and 220 A surge.

Use Value: 175°C T_j,max and 0.5 K/W R_thJC allow derating-free operation at 65°C ambient with forced air cooling.

Use Scenario: Input rectifier in double-conversion online UPS systems (100–500 kVA) with active PFC front-end.

IC Role / Device Role / Timing Role: Main DC-link charging diode handling 75 A RMS current with 10 ms overload capability.

Use Value: Low V_F (1.65 V) reduces conduction loss by 1.2 W per diode vs. 1.85 V alternatives, lowering thermal design cost by 15%.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH75S06CW	600 V, 75 A, 1.85 V V_F, 135 ns t_rr, TO-247AC package (cathode-isolated tab)	Higher conduction loss; less soft recovery (dI_rr/dt ≈ 1200 A/µs)	Prefer when lower cost is critical and thermal margin exists for higher V_F
IXYS MDD75-16N1	1600 V, 75 A, 2.1 V V_F, 250 ns t_rr, TO-247AD package (anode-isolated tab)	Over-specified voltage rating; slower recovery increases switching loss	Only suitable if system requires >1000 V blocking or legacy board layout mandates anode-isolation

Compared with STTH75S06CW and MDD75-16N1, IDW75E60FKSA1 delivers superior efficiency in 400–600 V systems due to its EmCon-optimized V_F/t_rr balance, softer recovery waveform, and tighter thermal resistance - making it optimal for space-constrained, high-efficiency motor and welding inverters.

FAQ

Is IDW75E60FKSA1 pin-compatible with standard TO-247 diodes?

Yes - IDW75E60FKSA1 uses the industry-standard PG-TO247-3 footprint with 2.54 mm lead pitch and identical mounting hole pattern. Its cathode-connected tab matches common TO-247 layouts, but thermal interface design must account for its 0.5 K/W R_thJC and isolation requirements.

What is the maximum recommended dI_F/dt for reliable operation?

The datasheet specifies dynamic parameters up to 1460 A/µs at T_j = 25°C. Testing confirms stable soft recovery up to 1600 A/µs; however, sustained operation above 1460 A/µs requires verification of peak I_rr and voltage overshoot in the target circuit.

Does IDW75E60FKSA1 require gate driving or external control?

No - IDW75E60FKSA1 is an uncontrolled two-terminal power diode. It conducts when anode voltage exceeds cathode voltage by >1.65 V and blocks when reverse biased up to 600 V. No gate signal, biasing, or auxiliary circuitry is needed.

Can IDW75E60FKSA1 be paralleled without current-sharing resistors?

Yes - its positive V_F temperature coefficient ensures natural current balancing across parallel units. Successful paralleling requires matched layout symmetry, identical thermal paths, and <5% interconnect inductance mismatch per leg, as validated in Infineon's application note AN2015-07.
