Product details
Overview
DD800S45KL3B5NPSA1 from Infineon is a highly insulated 4500 V, 800 A nominal reverse-blocking diode module for high-power inverter legs in medium-voltage converters. It features 10.4 kV AC/60 s isolation, AlSiC baseplate, CTI > 600, and 25.5 K/kW junction-to-case thermal resistance. Used in traction drives and wind turbine converters requiring surge current capability up to 1600 A.
For engineers reviewing the DD800S45KL3B5NPSA1 datasheet, DD800S45KL3B5NPSA1 pinout, DD800S45KL3B5NPSA1 application, or DD800S45KL3B5NPSA1 equivalent, key selection criteria include VRRM = 4500 V, IFRM = 1600 A, isolation voltage = 10.4 kV AC/60 s, creepage distance = 64.0 mm (terminal-to-heatsink), and thermal resistance RthJC = 25.5 K/kW per diode.
Technical Context
This module implements a single high-voltage, high-current fast recovery diode optimized for anti-parallel operation with FZ800R45KL3_B5 IGBTs in multi-level inverter topologies. Its design supports DC stability under 3000 V DC bias and dynamic robustness against repetitive 3300 A/µs reverse recovery di/dt stress.
The AlSiC baseplate enables >10,000 thermal cycles between -50 °C and 125 °C, while the AlN internal insulation and 56.0 mm terminal-to-terminal creepage meet IEC 60747/60749 industrial qualification requirements for medium-voltage converter systems.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage diode module applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DD800S45KL3_B5 | Same die, identical electrical specs, but lacks NPSA1 suffix indicating enhanced production screening and extended qualification testing. | No difference in motor drive or traction use; NPSA1 adds traceability for aerospace-grade BOMs. | Select NPSA1 for programs requiring full IEC 60747-9 Annex A compliance documentation. |
| DD1000S45KL3_B5 | Higher IF nom = 1000 A, same VRRM = 4500 V, but 32.0 K/kW RthJC and 12.5 kV isolation - larger footprint and higher thermal impedance. | Suitable only where space allows larger 62 mm variant and where 1000 A rating is required; not drop-in compatible. | Choose only when 200 A headroom is mandatory and thermal margin permits higher RthJC. |
Compared with DD800S45KL3_B5, the NPSA1 variant adds production traceability and extended life testing without altering electrical performance; versus DD1000S45KL3_B5, it trades 200 A rating for lower thermal resistance and smaller footprint-critical for space-constrained traction inverters.

FAQ
What is the maximum allowable case temperature for continuous operation?
The DD800S45KL3B5NPSA1 is rated for continuous operation with case temperature up to 125 °C, verified per IEC 60747-9. At this temperature, forward voltage remains ≤3.00 V at 800 A, and thermal resistance RthJC stays at 25.5 K/kW. Exceeding 125 °C risks accelerated degradation of AlN isolation and solder joint fatigue.
Is this module compatible with FZ800R45KL3_B5 IGBTs in a half-bridge configuration?
Yes-DD800S45KL3B5NPSA1 is specifically designed as the companion diode for FZ800R45KL3_B5 in half-bridge modules. Matching VRRM (4500 V), thermal characteristics, and package outline ensure balanced voltage sharing and synchronized thermal cycling. Dynamic data in the datasheet confirms co-optimization for 3300 A/µs di/dt conditions.
Does the NPSA1 suffix indicate a different pinout or package dimension?
No-the NPSA1 suffix denotes an enhanced manufacturing lot with extended qualification per IEC 60747-9 Annex A, including additional thermal cycling and humidity testing. Mechanical dimensions, terminal layout (A+, K−, NC), and screw torque specifications (M6 module mount, M8 terminals) are identical to DD800S45KL3_B5.
What is the recommended thermal interface material for heatsink mounting?
Infineon specifies thermal grease with λ = 1 W/(m·K) for RthCH calculation (21.0 K/kW). For optimal performance, use non-silicone, pump-out resistant grease such as Dow Corning TC-5000 or Henkel Loctite ABLESTIK 87-2. Avoid silicone-based pastes that degrade under thermal cycling; ensure uniform 0.08–0.12 mm bond line thickness per application note AN2018-05.
