Product details
Overview
IDW50E60FKSA1 from Infineon Technologies is a 600 V, 50 A fast-switching emitter-controlled diode optimized for high-frequency PFC stages in industrial power supplies and motor drives. It delivers 1.65 V forward voltage at 50 A and 25 °C, 115 ns reverse recovery time, and operates up to 175 °C junction temperature-enabling compact, thermally robust designs in 30 kHz switching applications.
For engineers reviewing the IDW50E60FKSA1 datasheet, IDW50E60FKSA1 pinout, IDW50E60FKSA1 application, or IDW50E60FKSA1 equivalent, key selection criteria include reverse recovery charge (1.50 µC at 25 °C), soft switching behavior, low di/dt-induced peak reverse current (30.0 A), and TO-247-3 package thermal resistance (0.80 K/W).
Technical Context
This emitter-controlled diode uses a proprietary structure that integrates gate-controlled carrier injection to suppress minority-carrier tail current, enabling faster, softer recovery than standard ultrafast diodes. Its dynamic performance is characterized under standardized inductive-load conditions (VR = 400 V, IF = 50 A, diF/dt = 1200 A/µs).
The device exhibits strong temperature stability: Qrr increases from 1.50 µC at 25 °C to 4.10 µC at 175 °C, while trr extends from 115 ns to 192 ns-critical for thermal-aware PFC design across full operating range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - supports DC-link voltages up to 400 V with 1.5× safety margin in boost PFC topologies |
| IF | 50 A continuous - rated at TC = 100 °C, enabling high-current conduction without derating in forced-air-cooled systems |
| VF | 1.65 V @ 50 A, 25 °C - reduces conduction loss by ~12% vs. comparable 1.85 V diodes at same current |
| Qrr | 1.50 µC @ 25 °C - lowers switching loss and EMI in high-frequency PFC controllers |
| trr | 115 ns @ 25 °C - enables stable operation up to 30 kHz with minimal turn-off overshoot |
| Tvjmax | 175 °C - allows sustained operation in enclosed industrial enclosures without active cooling |
| Rth(j–c) | 0.80 K/W - supports direct heatsink mounting with predictable thermal budget in TO-247 footprint |
Pinout & Package
Supplied in PG-TO247-3 package with isolated mounting flange and screw-hole compatibility for M3 fasteners. Thermal path optimized via copper baseplate directly bonded to silicon die.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Not connected | Electrically isolated terminal; must remain unconnected to avoid parasitic coupling or mechanical stress |
| Pin 2 | Cathode | Main current exit path; connects to output rail or switch node in boost PFC configuration |
| Pin 3 | Anode | Main current entry path; ties to AC input rectifier output or inductor return in continuous-conduction-mode PFC |
Key Features
| Feature | Design Value |
|---|---|
| Emitter-controlled architecture | Eliminates minority-carrier storage tail, reducing Qrr and enabling zero-voltage switching compatibility |
| Soft recovery characteristic | Peak reverse recovery current limited to 30.0 A with controlled di/dt (−470 A/µs), minimizing snubber stress |
| Pb-free, RoHS-compliant plating | Meets IPC-J-STD-020 moisture sensitivity level 1 (MSL1) for reflow assembly without baking |
| Easy paralleling capability | Positive temperature coefficient of VF ensures natural current sharing across multiple devices on shared heatsink |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fast-switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH50W06D | 600 V, 50 A, 1.75 V VF, 200 ns trr, 3.2 µC Qrr - higher conduction and switching loss | Requires larger heatsink and snubber network in 30 kHz PFC due to harder recovery | Prefer where cost sensitivity outweighs efficiency targets and thermal constraints are relaxed |
| IXYS MDD50-16N1 | 600 V, 50 A, 1.70 V VF, 140 ns trr, 2.4 µC Qrr - moderate improvement over STTH but no emitter control | Lacks soft recovery signature; exhibits higher EMI in high-di/dt CrM PFC | Suitable for fixed-frequency CCM PFC where EMI filtering is already present |
Compared with STTH50W06D and IXYS MDD50-16N1, IDW50E60FKSA1 delivers superior thermal margin (175 °C vs. 150 °C), lower Qrr, and intrinsic soft switching-making it optimal for space-constrained, high-efficiency 25–30 kHz industrial PFC designs where thermal headroom and EMI compliance are critical.

FAQ
What is the maximum recommended case temperature for continuous operation?
The device is rated for 50 A continuous forward current at TC = 100 °C. Operation above this requires derating per Figure 2 in the datasheet; at TC = 125 °C, maximum IF drops to ~42 A. Exceeding 175 °C junction temperature risks irreversible degradation of the emitter-controlled structure.
Can IDW50E60FKSA1 be paralleled without external current-sharing resistors?
Yes-its positive temperature coefficient of forward voltage ensures inherent current balancing. At 50 A per device, measured VF increases by ~12 mV/°C, enabling stable parallel operation on a common heatsink with ≤5 °C thermal gradient between units.
Is Pin 1 internally connected or electrically floating?
Pin 1 is electrically isolated and not connected to any internal structure. It serves only as a mechanical alignment aid and must remain unconnected in PCB layout to prevent unintended coupling or mechanical stress on the leadframe.
How does reverse recovery performance change at elevated junction temperature?
At 175 °C, Qrr rises to 4.10 µC (+173%) and trr extends to 192 ns (+67%) versus 25 °C values. This must be accounted for in thermal design-PFC controllers should be configured to maintain trr margin even at worst-case thermal conditions.
