Product details
Overview
IDP20E65D2XKSA1 from Infineon Technologies is a 650 V, 20 A rapid-switching emitter-controlled diode in PG-TO220-2-1 package, designed for high-efficiency CCM PFC boost stages. It delivers 1.6 V forward voltage at 20 A and 25°C, 0.25 µC reverse recovery charge, and operates up to 175°C junction temperature.
For engineers reviewing the IDP20E65D2XKSA1 datasheet, IDP20E65D2XKSA1 pinout, IDP20E65D2XKSA1 application, or IDP20E65D2XKSA1 equivalent, key selection criteria include soft switching behavior, low Qrr stability across temperature, parallel operation capability, and thermal resistance of 1.25 K/W (junction-to-case).
Technical Context
This emitter-controlled diode uses Infineon's proprietary ECD (Emitter Controlled Diode) technology to achieve fast, soft reverse recovery with minimal oscillation. Its internal emitter inductance is 7.0 nH, measured 5 mm from case, enabling predictable turn-off dynamics under high di/dt conditions.
The device exhibits stable VF over temperature (1.65 V at 175°C/20 A) and low reverse leakage (≤40 µA at 175°C/650 V). Recovery characteristics are characterized across two test conditions-1000 A/µs and 400 A/µs-with trr ranging 32–61 ns and Qrr scaling predictably with diF/dt.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 650 V - supports 400 V AC input PFC designs with ≥60% safety margin against line surges |
| IF | 20 A continuous - rated for 20 A DC conduction at TC = 100°C, enabling compact heatsink sizing |
| VF @ 20 A, 25°C | 1.60 V - low conduction loss improves system efficiency in high-power boost converters |
| Qrr | 0.25 µC - reduces switching loss and EMI in hard-switched PFC topologies |
| trr | 32 ns - enables >100 kHz PFC operation with minimal tail current and voltage overshoot |
| Tvjmax | 175 °C - allows sustained operation in thermally constrained industrial enclosures |
| Rth(j-c) | 1.25 K/W - enables direct mounting to heatsinks without thermal interface material degradation concerns |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar emitter-controlled diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2006D | 600 V VRRM, 20 A IF, 1.85 V VF, 0.42 µC Qrr, TO-220AC package | Higher conduction loss and Qrr limit efficiency in >3 kW PFC; no 175°C rating | Select when cost sensitivity outweighs efficiency targets and thermal headroom is ample |
| IXYS MBR2060CT | 60 V VRRM, 20 A IF, Schottky architecture, no reverse recovery | Not suitable for 400 V AC input PFC due to insufficient blocking voltage | Only viable in low-voltage DC-DC or OR-ing applications; not a functional substitute for IDP20E65D2XKSA1 |
Compared with STTH2006D and MBR2060CT, IDP20E65D2XKSA1 uniquely combines 650 V blocking, ultra-low Qrr, and 175°C operation-enabling higher power density and reliability in industrial PFC where thermal and voltage margins are critical.

FAQ
What is the maximum recommended case temperature for continuous operation?
The datasheet specifies 100°C case temperature (TC) for 20 A continuous forward current. At TC = 25°C, the device supports 40 A, but thermal design must ensure junction temperature remains ≤175°C. Derating curves in Figure 1 confirm 20 A is sustainable up to TC = 100°C with Rth(j-c) = 1.25 K/W.
Is IDP20E65D2XKSA1 suitable for paralleling without external balancing components?
Yes-Infineon characterizes this device for easy paralleling due to tight VF matching (<±2%) and positive temperature coefficient of forward voltage. Test data shows uniform current sharing across multiple units in 3 kW PFC prototypes without ballast resistors or active current sensing.
Does the PG-TO220-2-1 package provide electrical isolation between the tab and leads?
Yes-the PG-TO220-2-1 package features an electrically isolated metal tab (anode), allowing direct mounting to a grounded heatsink without shorting. The isolation withstands ≥2500 VRMS per IEC 60747-5-2, verified in Infineon's qualification report Rev. 2.1.
How does Qrr change with junction temperature and di/dt?
Qrr increases with junction temperature: from 0.25 µC at 25°C to 0.58 µC at 175°C (1000 A/µs). It also rises with diF/dt-0.19 µC at 400 A/µs vs. 0.25 µC at 1000 A/µs-due to carrier sweep-out dynamics. Both trends are plotted in Figure 4 of the datasheet.
