Product details
Overview
DD340N18SHPSA1 from Infineon Technologies is a dual-arm industrial rectifier diode module with 1800 V repetitive peak reverse voltage (VRRM), 330 A average on-state current (IFAVM) at TC = 100 °C, and 10 kA non-repetitive surge current (IFSM). It features solder-bond construction, electrically insulated Al₂O₃ baseplate, and is designed for high-power AC/DC conversion in drive inverters and UPS systems.
For engineers reviewing the DD340N18SHPSA1 datasheet, DD340N18SHPSA1 pinout, DD340N18SHPSA1 application, or DD340N18SHPSA1 equivalent, key selection criteria include thermal resistance (RthJC = 0.086 K/W per arm), threshold voltage (VT0 = 0.81 V), slope resistance (rT = 0.3 mΩ), and isolation rating (3.6 kV RMS).
Technical Context
This dual-diode module implements a two-arm, common-cathode configuration optimized for single-phase and three-phase bridge rectification. Its solder-bond interconnect ensures low parasitic inductance and robust thermal coupling between silicon dies and the insulated copper baseplate.
Rated for 130 °C maximum junction temperature and -40 °C to +130 °C operating case temperature range, it supports high-duty-cycle operation in industrial power supplies where thermal stability and electrical isolation are critical.

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 |
|---|---|---|---|
| IXYS MDD340-18N1 | Same VRRM (1800 V), slightly higher IFAVM (340 A), RthJC = 0.082 K/W, uses press-pack instead of solder-bond | Press-pack construction requires higher clamping force and different heatsink interface; less tolerant of thermal cycling | Select when existing press-pack heatsink infrastructure exists and solder-bond reliability is not required |
| Mitsubishi CM300DY-18H | 1800 V VRRM, 300 A IFAVM, RthJC = 0.095 K/W, integrated NTC sensor, different pin layout | NTC enables real-time junction temperature monitoring; lower current rating requires parallel use for same output | Select when closed-loop thermal protection or predictive maintenance is prioritized over raw current density |
Compared with MDD340-18N1 and CM300DY-18H, DD340N18SHPSA1 offers superior thermal resistance and solder-bond reliability for high-cycle industrial environments, while trading off integrated sensing and press-pack compatibility.

FAQ
What is the maximum allowable case temperature for continuous operation?
The maximum allowable case temperature (TC) for continuous operation is 100 °C, at which the device delivers its rated 330 A average on-state current (IFAVM). Operation up to 130 °C case temperature is permitted only for short durations defined by transient thermal impedance curves, not steady-state duty.
Is the baseplate electrically isolated, and what is its isolation voltage rating?
Yes, the baseplate is electrically isolated using an Al₂O₃ ceramic layer compliant with IEC 61140 Class 1 basic insulation. It is rated for 3.6 kV RMS at 50 Hz for 1 second and 3 kV RMS for 1 minute, verified per standard insulation test protocols.
Can DD340N18SHPSA1 be used in a six-pulse bridge configuration?
Yes-two DD340N18SHPSA1 modules (totaling six diode arms) are commonly deployed in three-phase six-pulse rectifier bridges. Each module provides two arms; proper gate-drive sequencing is not required since it is an uncontrolled rectifier.
What torque values are specified for mechanical and electrical terminals?
Mechanical mounting screws (M1) require 5 Nm ±15% torque; electrical terminal screws (M2) require 9 Nm ±15% torque. Exceeding these values risks damaging the ceramic isolation or deforming terminal posts, compromising thermal contact or electrical integrity.
