Product details
Overview
D1600U45X122XPSA1 from Infineon Technologies is a press-pack, stud-mounted, ultra-high-power fast recovery diode designed for medium-voltage converter freewheeling and snubber applications. It delivers 4500 V repetitive peak reverse voltage (VRRM), 1560 A average forward current (IFAVM) at TC = 65 °C, and 28 kA non-repetitive surge current (IFSM), with soft turn-off behavior at di/dt up to 5000 A/µs-used in IGCT- and IGBT-based traction and industrial drive inverters.
For engineers reviewing the D1600U45X122XPSA1 datasheet, D1600U45X122XPSA1 pinout, D1600U45X122XPSA1 application, or D1600U45X122XPSA1 equivalent, key selection criteria include clamping force range (36–65 kN), two-sided thermal resistance (RthJC = 7.5 K/kW), reverse recovery softness (FRRS = 1.6), and case non-rupture current rating.
Technical Context
This diode employs a silicon pressure-contact pellet structure with double-sided cooling capability, enabling high-current conduction while maintaining stable junction temperature up to 140 °C. Its soft recovery characteristic-quantified by FRRS = 1.6-minimizes voltage overshoot during turn-off under high di/dt conditions typical in hard-switched converters.
The device operates with full 50/60 Hz blocking capability across –40 °C to +150 °C storage and 0–140 °C operating ranges, and features a low slope resistance (rT = 0.994 mΩ) and threshold voltage (VT0 = 1.8 V), supporting efficient conduction in high-power DC-link freewheeling paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 4500 V - maximum repetitive reverse voltage the diode blocks without breakdown in AC line-frequency applications |
| IFAVM | 1560 A at TC = 65 °C - continuous average forward current sustainable with two-sided heatsink cooling |
| IFSM | 28000 A - peak non-repetitive surge current capability for short-circuit protection in converter legs |
| RthJC | 7.5 K/kW - thermal resistance from junction to case under two-sided cooling, critical for thermal design margin |
| FRRS | 1.6 - reverse recovery softness factor indicating controlled, low-overshoot turn-off behavior |
| Clamping Force | 36–65 kN - required mechanical compression range to ensure reliable thermal and electrical contact in press-pack assembly |
| Qr | 6 mAs - recovered charge during reverse recovery, directly influencing snubber sizing and switching loss |
Pinout & Package
Package: Press-pack, double-sided cooled, stud-mounted diode with anode and cathode terminals on opposite faces. Requires mechanical clamping between heatsinks.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Top Stud) | Forward current entry point | Electrically and thermally connected to upper heatsink; must be torqued within 36–65 kN clamping force range |
| Cathode (Bottom Stud) | Forward current exit point | Electrically and thermally connected to lower heatsink; polarity must be verified before mounting in series/parallel stacks |
Key Features
| Feature | Design Value |
|---|---|

| High DC blocking stability | VR(D) = 2800 V confirms robust long-term reverse bias reliability under DC-link conditions |
| Two-sided thermal path | RthJC = 7.5 K/kW enables symmetrical heat extraction, supporting >2 MW turn-off loss handling (PRQ = 9 MW) |
| High case non-rupture current | Withstands 28 kA surge without mechanical failure-critical for fault ride-through in grid-connected converters |
Applications
| IGCT Freewheeling | High-Power Traction Inverter |
|---|---|
Use Scenario: Freewheeling path in 4.16 kV medium-voltage IGCT-based back-to-back converters for wind turbine pitch control. IC Role / Device Role / Timing Role: Bidirectional energy recirculation path during IGCT turn-off; absorbs reactive energy from motor windings.

IC Role / Device Role / Timing Role: Rapidly conducts multi-kiloampere pulses (IFSM = 28 kA) with <250 V forward recovery peak (VFRM). Use Value: High surge current capability and 140 °C max junction temperature support repetitive 10 ms pulse operation without thermal runaway. |
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 MDD1600-45 | VRRM = 4500 V, IFAVM = 1600 A, RthJC = 7.2 K/kW, FRRS ≈ 1.5 | Slightly higher average current rating but lower softness factor; requires tighter clamping force tolerance | Preferred where higher continuous current margin is prioritized over strict dv/dt control |
| Mitsubishi CM1600HA-45H | VRRM = 4500 V, IFAVM = 1500 A, RthJC = 8.1 K/kW, no published FRRS value | Lower thermal performance and uncharacterized recovery softness; validated only for 50 Hz line-frequency rectification | Suitable for legacy rectifier upgrades but not recommended for high-di/dt IGBT/IGCT freewheeling |
Compared with MDD1600-45 and CM1600HA-45H, D1600U45X122XPSA1 offers superior reverse recovery softness (FRRS = 1.6) and verified two-sided thermal performance (RthJC = 7.5 K/kW), making it optimal for hard-switched medium-voltage converters requiring both surge robustness and EMI-controlled turn-off.

FAQ
What is the required clamping force range for proper thermal and electrical contact?
The D1600U45X122XPSA1 requires a mechanical clamping force between 36 kN and 65 kN to ensure low contact resistance and uniform heat transfer across both anode and cathode interfaces. Under-torque risks thermal runaway; over-torque may deform the copper housing or damage the silicon pellet.
Does this diode support single-sided cooling, and how does it affect thermal performance?
Yes, single-sided cooling is supported but degrades thermal performance: RthJC increases to 13.3 K/kW (anode-cooled) or 17.2 K/kW (cathode-cooled). For rated IFAVM = 1560 A, two-sided cooling is mandatory; single-sided use requires derating to ≤950 A to maintain Tvj ≤ 140 °C.
How is reverse recovery softness (FRRS) measured, and why is FRRS = 1.6 significant?
FRRS is calculated as trr / tfr, where trr is total reverse recovery time and tfr is the time from peak reverse current to zero crossing. An FRRS of 1.6 indicates a gradual, non-abrupt current decay-reducing voltage overshoot and electromagnetic interference in high-di/dt switching circuits such as IGBT half-bridges.
Can D1600U45X122XPSA1 be paralleled with other diodes, and what matching criteria are required?
Parallel operation is feasible but requires strict matching: VFRM ≤ ±5 V, Qr ≤ ±0.3 mAs, and rT ≤ ±0.05 mΩ across units. Uneven current sharing arises from forward voltage mismatch; active current balancing via gate-controlled series switches is not applicable-only passive thermal and electrical symmetry suffices.
