Product details
Overview
DZ540N26KHPSA1 from Semikron is a press-pack dual-diode rectifier module rated for 2600 V repetitive peak reverse voltage, 540 A average on-state current at TC = 100°C, and 1150 A RMS on-state current, designed for high-power industrial AC/DC conversion in six-pulse bridge configurations.
For engineers reviewing the DZ540N26KHPSA1 datasheet, DZ540N26KHPSA1 pinout, DZ540N26KHPSA1 application, or DZ540N26KHPSA1 equivalent, key selection criteria include junction-to-case thermal resistance (0.078 °C/W), surge current capability (16.5 kA @ 10 ms), threshold voltage (0.78 V), and pressure-contact Si pellet construction with AlN isolation.
Technical Context
This dual-diode module implements a B6 (six-pulse) bridge arm configuration with two independent high-current diode elements housed in a single insulated metal-ceramic package. Each diode arm supports up to 16.5 kA non-repetitive surge current and exhibits a slope resistance of 0.31 mΩ at maximum junction temperature.
Thermal performance is defined by transient junction-to-case impedance (ZthJC) with analytical R-τ network parameters, and case-to-heatsink resistance of 0.02 °C/W. It operates across -40°C to +150°C case temperature range with 150°C maximum junction temperature rating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 2600 V - Maximum repetitive reverse blocking voltage per diode arm, defining DC link voltage headroom in rectifier stacks. |
| IFAVM | 540 A - Average forward current per arm at TC = 100°C, used for continuous thermal design in forced-air-cooled systems. |
| IFRMSM | 1150 A - RMS forward current rating, critical for I²t-based fuse coordination and conduction loss calculation. |
| vF max | 1.64 V - Maximum forward voltage at 2200 A and Tvj max, directly determining conduction losses in high-current operation. |
| RthJC | 0.078 °C/W - Steady-state thermal resistance from junction to case, setting minimum heatsink requirement for thermal management. |
| Qr | Measured recovered charge dependent on -di/dt and iFM - Governs snubber sizing and EMI generation during commutation. |
| IFS M | 16500 A - Non-repetitive surge current rating at 10 ms, specifying short-circuit withstand capability in line-commutated drives. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage, high-current rectifier module applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SKD540N26HPSA1 | Identical electrical specs; uses Semikron's newer SKiiP® press-pack housing with enhanced creepage (18 mm) and tighter RthJC tolerance (0.0745 °C/W). | Preferred for new designs requiring extended lifetime under humidity or pollution; validated for IP65-rated enclosures. | Select when long-term field reliability in harsh environments outweighs cost sensitivity. |
| DD540N26K | Same VRRM/IFAVM ratings but higher RthJC (0.082 °C/W); uses older DIN 41612-compatible footprint and lacks ZthJC analytical model. | Suitable only for legacy retrofits where mechanical interchangeability with discontinued modules is mandatory. | Choose only for exact form-fit replacement in existing installations with no thermal margin available. |
Compared with SKD540N26HPSA1 and DD540N26K, DZ540N26KHPSA1 offers balanced thermal performance and full transient modeling support at lower cost than SKiiP®, while providing modern packaging and documentation lacking in the legacy DD-series.

FAQ
What is the maximum allowable case temperature for continuous operation?
The DZ540N26KHPSA1 supports continuous operation up to +150°C case temperature, as specified in its thermal derating curves. At this limit, the average forward current must be reduced to 540 A, and thermal design must ensure junction temperature remains ≤150°C using the provided RthJC and ZthJC models.
Does this module require external snubbers in six-pulse bridge operation?
Snubbers are recommended due to measurable recovered charge (Qr) that varies with -di/dt and forward current. The datasheet provides Qr vs. -di/dt curves for Tvj max and vRM = 0.8×VRRM, enabling precise RC snubber design to limit voltage overshoot during commutation.
Can DZ540N26KHPSA1 be paralleled with identical units?
Yes-parallel operation is supported via matched forward voltage characteristics (vF max = 1.64 V at 2200 A) and symmetrical thermal resistance (RthJC = 0.078 °C/W). Successful paralleling requires identical busbar inductance, uniform clamping force, and balanced cooling across all modules.
What is the insulation test voltage rating and duration?
The module is rated for 3.6 kV RMS insulation test voltage at 50 Hz for 1 second, and 3.0 kV RMS for 1 minute. These values apply to the internal AlN isolation barrier between the two diode arms and between each arm and the baseplate, as verified per IEC 60747-9.
