Product details
Overview
DZ540N22KHPSA1 from Semikron is a press-pack dual-diode rectifier module rated for 2200 V repetitive peak reverse voltage (VRRM), 540 A average on-state current (IFAVM) at TC = 100°C, and 1150 A RMS on-state current (IFRMSM), designed for high-power industrial AC/DC conversion in six-pulse bridge configurations.
For engineers reviewing the DZ540N22KHPSA1 datasheet, DZ540N22KHPSA1 pinout, DZ540N22KHPSA1 application, or DZ540N22KHPSA1 equivalent, key selection criteria include junction-to-case thermal resistance (0.078 °C/W), surge current capability (16.5 kA @ 10 ms), and pressure-contact Si pellet construction with AlN isolation for high-reliability traction and medium-voltage drive systems.
Technical Context
This dual-diode module implements a B6 (six-pulse) bridge arm configuration with two independent, isolated anode-cathode paths per module. It uses silicon die with pressure-contact metallization and aluminum nitride (AlN) ceramic isolation to sustain 150 °C maximum junction temperature under continuous conduction.
Thermal performance is defined by transient junction-to-case impedance ZthJC (analytical R-τ model provided), with DC RthJC = 0.078 °C/W max and case-to-heatsink RthCH = 0.02 °C/W max. Electrical behavior includes 1.64 V max forward voltage at 2200 A and 40 mA max reverse leakage at VRRM and Tvj max.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 2200 V - Maximum repetitive reverse blocking voltage per diode arm; defines usable DC bus voltage in B6 rectifiers up to ~1500 VDC. |
| IFAVM | 540 A @ TC = 100°C - Continuous average forward current per arm; sets steady-state power handling in forced-air-cooled drives. |
| IFRMSM | 1150 A - RMS on-state current rating; determines I²t-based thermal stress during asymmetrical load cycles. |
| IFS M | 16.5 kA @ 10 ms - Non-repetitive surge current; supports short-circuit ride-through in motor drives without fuse coordination failure. |
| RthJC | 0.078 °C/W max - Junction-to-case thermal resistance; enables direct mounting to liquid or high-efficiency air-cooled heatsinks. |
| vF max | 1.64 V @ Tvj max, iF = 2200 A - Forward voltage drop; directly impacts conduction loss (P = vF × IFAVM) in high-current rectification stages. |
| Qr | Not specified in provided data - Recovered charge not listed; softness and reverse recovery behavior require separate characterization for EMI-sensitive applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-current rectifier module applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SKKT 540/22E | Same VRRM (2200 V) and IFAVM (540 A), but uses solder-bonded die and lower surge rating (14 kA). | Limited to natural-convection cooling due to higher RthJC (0.095 °C/W); unsuitable for forced-air or liquid-cooled high-dynamic loads. | Select when cost sensitivity outweighs surge robustness and thermal efficiency requirements. |
| DD900N22K | Higher IFAVM (900 A) and VRRM (2200 V), but larger package (1200 g) and no documented AlN isolation. | Requires additional creepage extension hardware in marine or railway applications; lacks certified 3.6 kV insulation test. | Select only when higher current headroom is mandatory and system-level isolation can be engineered externally. |
Compared with SKKT 540/22E and DD900N22K, DZ540N22KHPSA1 delivers superior thermal efficiency (0.078 °C/W), certified high-voltage isolation (3.6 kV), and industry-leading surge tolerance (16.5 kA), making it optimal for mission-critical, space-constrained, and high-reliability rectifier stacks.

FAQ
What is the maximum allowable case temperature for DZ540N22KHPSA1?
The maximum allowable case temperature is not explicitly specified as a standalone limit; instead, the device is rated for IFAVM = 540 A at TC = 100°C and supports operation up to Tvj max = 150°C. Thermal design must ensure junction temperature remains ≤150°C using RthJC = 0.078 °C/W and RthCH = 0.02 °C/W, with case temperature determined by heatsink performance and ambient conditions.
Does DZ540N22KHPSA1 support paralleling of multiple modules?
Yes-DZ540N22KHPSA1 is designed for parallel operation in multi-module rectifier stacks. Its matched forward voltage (vF max = 1.64 V) and low slope resistance (rT = 0.31 mΩ) minimize current imbalance. Successful paralleling requires identical mounting torque (M2 = 12 Nm), symmetrical busbar layout, and active current-sharing control in high-dynamic applications.
What is the insulation test voltage rating for this module?
DZ540N22KHPSA1 has a certified insulation test voltage of 3.6 kV RMS at 50 Hz for 1 second, verified per its datasheet. This rating applies to the internal AlN isolation barrier between the Si die and baseplate, ensuring compliance with IEC 60747-9 for high-voltage power modules used in safety-critical systems.
Can DZ540N22KHPSA1 be used in single-phase rectifier topologies?
Yes-it supports both single-phase (B2) and three-phase (B6) bridge configurations. In B2 mode, it delivers up to 3500 A peak output current with RthCA = 0.020 °C/W (forced cooling), as shown in Figure 7 of the datasheet. However, its dual-arm architecture is optimized for balanced three-phase loading, and single-phase use requires careful thermal derating due to asymmetric conduction angles.
