Product details
Overview
DD89N18KHPSA1 from Semikron is a press-pack dual-diode rectifier module rated for 1800 V repetitive peak reverse voltage (VRRM), 89 A average on-state current (IFAVM) per arm at TC = 100°C, and 140 A RMS on-state current (IFRMSM), designed for high-power industrial AC/DC conversion in six-pulse bridge (B6) and two-pulse bridge (B2) configurations.
For engineers reviewing the DD89N18KHPSA1 datasheet, DD89N18KHPSA1 pinout, DD89N18KHPSA1 application, or DD89N18KHPSA1 equivalent, key selection criteria include junction-to-case thermal resistance (0.215 °C/W per arm), surge current capability (2.4 kA at Tvj max), threshold voltage (0.75 V), and pressure-contact Si pellet construction with AlN isolation.
Technical Context
This dual-arm diode module implements a common-cathode configuration with isolated Si pellets mounted via compression on an AlN ceramic substrate. Each arm supports independent conduction with full 180° sinusoidal conduction angle capability and is rated for 150 °C maximum junction temperature.
Thermal performance is defined by transient junction-to-case impedance (ZthJC) with analytical R-τ elements, and case-to-heatsink resistance (RthCH) of 0.10 °C/W per arm. Mechanical mounting uses M2 terminals with 4 Nm torque and M1 housing bolts at ±10% tolerance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1800 V - Maximum repetitive reverse blocking voltage per arm; defines usable DC bus voltage in B6 rectifiers up to 1200 V line-to-line. |
| IFAVM | 89 A - Average forward current per arm at TC = 100°C; sets continuous output rating in forced-air-cooled motor drives. |
| IFRMSM | 140 A - RMS forward current per arm; determines I²t-based fuse coordination and thermal cycling endurance. |
| VF max | 1.5 V - Maximum on-state voltage at Tvj max and 300 A; directly impacts conduction loss and heatsink sizing. |
| RthJC | 0.215 °C/W - Junction-to-case thermal resistance per arm under DC conditions; enables thermal modeling of die temperature rise. |
| Qr | Not specified - Recovered charge not provided in datasheet; softness not characterized for EMI-sensitive applications. |
| VRSM | 1900 V - Non-repetitive peak reverse voltage; defines short-term overvoltage withstand during transients. |
| I²t | 28,800 A²s - Surge energy handling at Tvj max and 10 ms pulse; used for short-circuit protection coordination. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage dual-diode rectifier module applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DD89N16KHPSA1 | 1600 V VRRM, 0.225 °C/W RthJC per module (not per arm), same 89 A IFAVM. | Limited to 1000 VDC bus systems; higher thermal resistance requires larger heatsink area. | Select when system overvoltage margin is ≤100 V and space-constrained cooling is acceptable. |
| DD105N18KHPSA1 | 105 A IFAVM, 1800 V VRRM, 0.185 °C/W RthJC per arm, 1900 V VRSM. | Higher current rating enables 18% higher output in same footprint; requires upgraded gate driver and snubber design. | Select when upgrading existing DD89N18KHPSA1-based designs for increased power without changing heatsink. |
Compared with DD89N16KHPSA1, DD89N18KHPSA1 provides 200 V higher blocking margin and lower per-arm thermal resistance-critical for 1200 VDC bus stability. Against DD105N18KHPSA1, it trades 16 A current headroom for tighter thermal budget control in thermally constrained enclosures.

FAQ
What is the maximum allowable case temperature for DD89N18KHPSA1?
The maximum case temperature is not independently specified; instead, the device is rated for 150 °C maximum junction temperature (Tvj max) with derated current versus case temperature curves provided. At TC = 100°C, IFAVM = 89 A per arm. Operation above TC = 100°C requires linear derating to maintain Tvj ≤ 150°C.
Does DD89N18KHPSA1 include internal thermal sensors?
No, DD89N18KHPSA1 does not integrate thermal sensors. Temperature monitoring must be implemented externally using case-mounted NTC thermistors or infrared sensors placed on the baseplate, referenced to the provided RthJC and RthCH thermal resistance values for junction estimation.
Can DD89N18KHPSA1 be used in parallel configurations?
Yes, but only with active current balancing-such as matched dynamic impedance, identical busbar inductance, and synchronized thermal mounting-due to inherent VF mismatch between arms. Parallel use beyond two modules per phase is not recommended without individual arm current sensing and closed-loop control.
What is the creepage distance and why does it matter?
The creepage distance is 15 mm, measured across the AlN ceramic surface between high-voltage terminals. This value ensures safe isolation under pollution degree 2 conditions per IEC 60664-1, enabling use in industrial environments with conductive dust or humidity without external potting or conformal coating.
