Product details

Overview

D2201N45TXPSA1 from Infineon Technologies is a high-power, press-pack crowbar diode designed for voltage-source converter (VSC) snubber and overvoltage protection circuits in medium-voltage drive and HVDC systems. It delivers 4500 V repetitive peak reverse voltage (V_RRM), 2060 A average forward current at T_C = 100 °C (I_FAVM), and withstands 38 kA surge current (I_FSM) - enabling robust fault-current clamping in industrial grid-tied inverters.

For engineers reviewing the D2201N45TXPSA1 datasheet, D2201N45TXPSA1 pinout, D2201N45TXPSA1 application, or D2201N45TXPSA1 equivalent, key selection criteria include its two-sided cooling capability, 10 K/kW junction-to-case thermal resistance (R_thJC), clamping force range (27–45 kN), and pressure-contact Si-pellet construction - all critical for thermal reliability in high-energy crowbar protection schemes.

Technical Context

This device is a unidirectional, non-controlled, silicon-based power diode optimized for transient overvoltage suppression via crowbar action in DC-link circuits. Its design centers on high surge current handling (38 kA @ 10 ms) and stable blocking under 50/60 Hz AC line conditions across –40 °C to +140 °C junction temperature.

The diode employs a double-sided cooled, pressure-contact package with anode and cathode terminals accessible on opposite faces. Thermal performance is defined by analytical Z_thJC transient impedance models for anode-, cathode-, and two-sided cooling configurations - supporting precise thermal modeling in forced-air or liquid-cooled converter stacks.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	4500 V - Enables use in 3.3 kV–4.16 kV DC-link applications with safety margin against transients
I_FAVM	2060 A @ T_C = 100 °C - Sustains continuous conduction in high-power crowbar duty cycles
I_FSM	38000 A @ t_P = 10 ms - Absorbs short-circuit energy without rupture during converter faults
V_T0	0.688 V - Low threshold voltage ensures fast turn-on and minimal delay in crowbar activation
r_T	0.205 mΩ - Low slope resistance minimizes forward conduction loss and self-heating during clamping
R_thJC	10 K/kW (two-sided cooling) - Supports efficient heat extraction in stacked converter modules
Clamping Force	27–45 kN - Required mechanical load to maintain low contact resistance and thermal interface integrity

Pinout & Package

Package: Double-sided cooled, press-pack, stud-mounted diode with isolated anode and cathode terminals on opposite faces. Diameter: 100 mm; height: 26 mm; contact diameter: 62.8 mm; weight: ~850 g.

Pin/Terminal	Circuit Role	Design Meaning
Anode (Top Face)	Forward current entry point	Connected to DC-link positive side; requires ≥27 kN mechanical compression for low R_thCH
Cathode (Bottom Face)	Forward current exit point	Connected to crowbar ground path; enables two-sided heatsinking when mounted between cold plates

Key Features

Feature	Design Value
Full 50/60 Hz blocking over –40 °C to +140 °C	Ensures reliable off-state isolation in grid-synchronized converters across ambient extremes
High DC blocking stability	Maintains <100 mA reverse leakage at V_RRM and T_vj = 140 °C - prevents false triggering
High case non-rupture current	Withstands I_FSM without mechanical failure - critical for fail-safe crowbar operation
Two-sided thermal interface	Enables symmetric heat extraction from both anode and cathode faces - improves thermal derating in stacked designs

Applications

Medium-Voltage Drive Crowbar Protection

HVDC Converter Valve Snubber

Use Scenario: Fault-induced DC-link overvoltage in 3.3 kV industrial drives triggers immediate crowbar conduction to protect IGBTs.

IC Role / Device Role / Timing Role: High-current, low-delay crowbar diode activated within microseconds of overvoltage detection.

Use Value: Prevents IGBT destruction by diverting >30 kA fault current away from switching devices using validated 38 kA I_FSM rating.

Use Scenario: Transient overvoltage suppression during valve commutation failure in ±320 kV HVDC converter stations.

IC Role / Device Role / Timing Role: Passive snubber element absorbing stored energy from DC-link capacitors during thyristor misfiring.

Use Value: Maintains system availability by clamping voltage spikes before thyristor dv/dt limits are exceeded, leveraging 4500 V V_RRM and 10 K/kW R_thJC.

Wind Turbine Grid-Fault Ride-Through

Marine Propulsion System DC-Link Protection

Use Scenario: LVRT event causes rapid DC-link rise in full-scale converter wind turbines; crowbar diverts generator energy to dump resistor.

IC Role / Device Role / Timing Role: Primary overvoltage protection switch in passive crowbar circuit, triggered by control logic upon AC-side fault detection.

Use Value: Enables compliance with grid codes requiring 150 ms fault ride-through, supported by 3240 A I_FRMSM and 7220×10³ A²s I²t rating.

Use Scenario: Short-circuit in shipboard propulsion DC bus demands immediate energy diversion to avoid fire hazard or cable damage.

IC Role / Device Role / Timing Role: High-reliability crowbar element in redundant protection architecture for Class II marine electrical systems.

Use Value: Delivers fail-safe operation under vibration (50 m/s² @ 50 Hz) and wide storage temp (–40…+150 °C), meeting DNV-GL marine certification prerequisites.

Equivalent & Alternatives

The following parts are listed as comparable options for similar crowbar diode applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
DD900N45K	Higher V_RRM (4500 V same), lower I_FAVM (1800 A), higher R_thJC (12.5 K/kW)	Suitable for lower-duty-cycle crowbar use; less thermal headroom in continuous clamping	Select when system I_FSM demand <35 kA and thermal budget allows higher R_thJC
SKKH 105/45	Same V_RRM, lower I_FAVM (1050 A), single-sided cooling only, R_thJC = 17.3 K/kW	Limited to lower-power crowbar or auxiliary snubbing where space constraints prevent double-sided mounting	Choose only for retrofit into legacy single-cooled assemblies; not recommended for new high-reliability designs

Compared with DD900N45K and SKKH 105/45, D2201N45TXPSA1 provides superior thermal management (10 K/kW R_thJC), higher average current capacity (2060 A), and validated two-sided cooling - making it the preferred choice for new-build medium- and high-power crowbar systems demanding long-term reliability.

FAQ

What is the required clamping force for reliable thermal and electrical contact?

The D2201N45TXPSA1 requires a mechanical clamping force between 27 kN and 45 kN to ensure low contact resistance and optimal thermal transfer across the anode and cathode interfaces. Below 27 kN, R_thJC degrades significantly and forward voltage increases; above 45 kN risks pellet fracture. Torque specifications must follow Infineon's mounting guidelines for 100 mm press-pack housings.

Can this diode be used with single-sided cooling?

Yes, but with significant derating: R_thJC rises to 17.3 K/kW (anode-cooled) or 24 K/kW (cathode-cooled), reducing maximum I_FAVM by ~35%. The datasheet provides full transient Z_thJC curves for all three configurations. Two-sided cooling is strongly recommended to achieve rated 2060 A performance and thermal stability.

What is the maximum allowable junction temperature during surge events?

The absolute maximum junction temperature is 140 °C, and the device is rated for I_FSM = 38 kA at T_vj = 25 °C and 35 kA at T_vj = 140 °C (both for 10 ms). Transient thermal impedance data (page 5) must be used to verify peak T_vj does not exceed 140 °C under actual surge waveform and pre-heat conditions.

Is this diode suitable for use in aviation or medical life-support systems?

No - Infineon explicitly states that use in aviation, health-endangering, or life-support applications requires joint risk assessment, quality agreements, and ongoing product surveillance. D2201N45TXPSA1 is qualified for industrial and energy infrastructure use only; no extended qualification (e.g., DO-160, ISO 13485) is provided in the datasheet or public documentation.
