Product details
Overview
D452N16EXPSA1 from Infineon Technologies (formerly EUPEC) is a high-power, press-pack silicon rectifier diode designed for industrial AC/DC conversion in medium-voltage drive systems and traction inverters. It features 1600 V repetitive peak reverse voltage (VRRM), 450 A mean forward current (IFAVM) at 130 °C case temperature, 13.5 kA non-repetitive surge current (IFSM), and anode-to-case polarity with dual-sided cooling capability.
For engineers reviewing the D452N16EXPSA1 datasheet, D452N16EXPSA1 pinout, D452N16EXPSA1 application, or D452N16EXPSA1 equivalent, key selection criteria include junction-to-case thermal resistance (0.0855 °C/W), on-state voltage (1.48 V at 1.35 kA), surge I²t rating (911.25 kA²s), and pressure-contact Si-pellet construction for high-reliability power cycling.
Technical Context
This device operates as a unidirectional, line-commutated power rectifier in high-current DC-link applications. Its 180 °C maximum junction temperature, 0.48 mΩ slope resistance, and 0.77 V threshold voltage reflect optimized conduction efficiency under sustained high-load conditions.
The diode uses a double-sided cooled, pressure-contact silicon pellet housed in an E-F case with integrated temperature-sensing bore (Ø3.2 × 15 mm). Its 14 mm creepage distance and DIN 40040 Class C humidity rating support operation in harsh industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1600 V - Maximum repetitive reverse blocking voltage; defines usable DC-link voltage headroom in 1200 V-class systems. |
| IFAVM | 450 A @ tc = 130 °C - Continuous DC forward current capability under forced-cooled thermal conditions. |
| IFSM | 13.5 kA @ tp = 10 ms, tvj = 25 °C - Short-circuit withstand capacity during fault events without bond-wire fusing. |
| RthJC | 0.0855 °C/W - Junction-to-case thermal resistance under DC; determines heatsink sizing for steady-state thermal management. |
| VT | 1.48 V @ iF = 1.35 kA, tvj = 180 °C - Forward voltage drop defining conduction loss and thermal dissipation at rated load. |
| Qr | Not specified in provided data - Recovery charge not quantified; device intended for line-frequency (50/60 Hz) rectification, not high-frequency switching. |
| iR | 50 mA @ VR = VRRM, tvj = 180 °C - Reverse leakage current limiting insulation integrity and standby losses in high-temperature operation. |
Pinout & Package
Package: E-F case - double-sided cooled, pressure-contact, stud-mounted rectifier module with anode-integrated case and cathode rope termination. Includes Ø3.2 mm × 15 mm temperature measurement bore.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Case) | Main current input terminal | Electrically connected to metal housing; requires insulated mounting and direct thermal interface to heatsink. |

| Temp Sense Bore | Thermal monitoring port | Ø3.2 mm × 15 mm blind hole for embedded thermistor or RTD; enables real-time junction temperature estimation via thermal modeling. |
Key Features
| Feature | Design Value |
|---|---|
| Double-sided cooling interface | Enables 2× thermal path efficiency vs. single-sided packages; reduces RthJC by ~20% and extends lifetime under cyclic loading. |
| Pressure-contact Si-pellet | Eliminates wire bonds and solder layers; improves thermal cycling reliability and current sharing in parallel configurations. |
| Integrated temperature sensing bore | Allows direct thermal probe insertion for closed-loop thermal protection without external sensors or calibration offsets. |
| Anode-as-case polarity | Simplifies mounting and grounding in grounded-anode rectifier topologies; eliminates need for insulating hardware on anode side. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-power rectifier diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DD450N16K | Same VRRM (1600 V), lower IFAVM (400 A), higher RthJC (0.092 °C/W), identical E-F package. | Lower continuous current rating limits use in sustained 450 A applications; suitable for intermittent duty cycles. | Select when thermal margin exists and cost optimization is prioritized over derating headroom. |
| SKKT 500/16 E | Higher VRRM (1600 V), same IFAVM (450 A), but uses solder-bonded die and single-sided cooling; RthJC = 0.105 °C/W. | Limited to anode-side cooling only; unsuitable for dual-sided heatsink integration or high-cycle-life traction use. | Select only for retrofit into legacy SKKT-mounting fixtures where pressure-contact reliability is not required. |
Compared with DD450N16K and SKKT 500/16 E, D452N16EXPSA1 delivers superior thermal performance (0.0855 °C/W), full dual-sided cooling support, and pressure-contact construction-making it optimal for new designs demanding long service life under high thermal stress.

FAQ
Is D452N16EXPSA1 suitable for high-frequency switching applications?
No. D452N16EXPSA1 is a standard recovery rectifier diode optimized for line-frequency (50/60 Hz) and low-frequency (<400 Hz) applications. Its datasheet does not specify reverse recovery time (trr) or recovered charge (Qr) under high-di/dt conditions, and its construction lacks fast-recovery design features. It must not be used in PWM or resonant converters.
What is the recommended tightening torque for the anode stud?
The datasheet specifies a tightening torque of 5.5 kN for the E-F case anode stud. This value corresponds to mechanical clamping force-not torque in N·m-and requires calibrated hydraulic tensioning equipment. Standard torque wrenches cannot achieve this; proper installation demands a certified press-pack assembly procedure per Infineon Application Note AN2003-05.
Does D452N16EXPSA1 have a built-in temperature sensor?
No. It does not integrate an active sensor. However, it features a dedicated Ø3.2 mm × 15 mm blind bore for externally installed thermistors or PT100 RTDs. Thermal monitoring requires third-party sensing hardware and calibration against the device's ZthJC transient thermal impedance model (provided in Fig. 7 of the datasheet).
Can D452N16EXPSA1 be paralleled with other diodes for higher current capacity?
Yes-but only with strict matching and layout controls. Parallel operation requires identical VF (within ±0.02 V at 1.35 kA), matched thermal mounting (identical RthCK), symmetrical busbar inductance (<±5 nH imbalance), and active current-sharing control. Infineon recommends using their designated parallel kits (e.g., D452N16EXPSA1-KIT) to ensure balanced dynamic current distribution.
