Product details

Overview

D4810N22TVFXPSA1 from Infineon Technologies is a high-power, press-pack silicon rectifier diode designed for industrial AC/DC conversion in medium- to high-voltage thyristor-controlled rectifiers and phase-controlled converters. It delivers 4810 A average on-state current at 100°C case temperature, 2200 V repetitive peak reverse voltage, and 80 kA surge current (10 ms, T_vj = 25°C), serving as the main power-conducting element in 3-phase 6-pulse or 12-pulse traction and industrial drive systems.

For engineers reviewing the D4810N22TVFXPSA1 datasheet, D4810N22TVFXPSA1 pinout, D4810N22TVFXPSA1 application, or D4810N22TVFXPSA1 equivalent, key selection criteria include junction-to-case thermal resistance (0.0080 °C/W two-sided), forward voltage drop (1.45 V @ 10 kA), transient thermal impedance behavior under 50 Hz half-wave overload, and clamping force requirements (42–95 kN) for reliable pressure-contact mounting.

Technical Context

This device operates as a unidirectional, non-controlled power rectifier with no gate control-its conduction is determined solely by applied anode-cathode voltage polarity and magnitude. It features a planar-diffused silicon pellet with double-sided cooling capability, enabling high RMS current handling (10.9 kA) and robust I²t withstand (32 × 10³ A²s at 25°C).

The diode's on-state characteristic follows a four-parameter logarithmic model (A=1.181, B=1.391×10⁻⁵, C=−9.794×10⁻², D=1.031×10⁻²), and its reverse recovery charge Q_r varies from 1 µAs to 100 µAs depending on di/dt (1–100 A/µs) and forward current level (100–2000 A), critical for snubber design in line-commutated converters.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	2200 V - Maximum repetitive reverse blocking voltage; defines usable DC bus voltage range in 6-pulse rectifiers up to ~1500 V DC output.
I_FAVM @ T_C = 100°C	4810 A - Average forward current rating under continuous DC or full-sine conduction with two-sided heatsink cooling.
I_FSM (10 ms)	80,000 A - Short-circuit surge current capacity; supports fault ride-through in motor drives without immediate failure.
R_thJC (two-sided)	0.0080 °C/W - Junction-to-case thermal resistance; determines minimum required heatsink thermal conductance for safe 160°C junction operation.
v_F @ 10 kA, T_vj = 160°C	1.45 V - Forward voltage drop at rated peak load; directly sets conduction loss (P ≈ 14.5 kW per device at 10 kA).
Q_r @ 2000 A, −di/dt = 50 A/µs	~30 µAs - Recovered charge during turn-off; governs snubber capacitor sizing and switching loss in forced-commutated auxiliary circuits.
Clamping Force	42–95 kN - Required mechanical compression for low-resistance, stable pressure contact between Si pellet and copper electrodes.

Pinout & Package

Package: Press-pack, double-sided cooled, stud-mounted diode with isolated anode and cathode terminals. Requires external clamping assembly and thermally conductive interface material (e.g., indium foil or silver paste) between pellet and heatsinks.

Pin/Terminal	Circuit Role	Design Meaning
Anode (stud)	Positive current entry point under forward bias	Mechanically rigid, threaded copper stud; must be torqued to specified clamping force to ensure low contact resistance and thermal transfer.
Cathode (stud)	Current exit path during conduction	Electrically isolated copper stud; forms second thermal interface surface-requires identical clamping and surface finish as anode.

Key Features

Feature	Design Value
Double-sided cooling architecture	Enables 10.9 kA RMS current handling and reduces thermal bottleneck vs. single-sided packages-critical for high-duty-cycle industrial rectifiers.
Low slope resistance (r_T = 0.062 mΩ)	Minimizes forward voltage rise under overcurrent, improving short-term overload tolerance and reducing thermal runaway risk.
High I²t rating (32 × 10³ A²s)	Supports coordination with upstream fuses rated for ≥80 kA interrupting capacity in 3-phase AC distribution feeders.
Controlled reverse recovery (Q_r < 100 µAs)	Reduces voltage overshoot and EMI during commutation-enables use with standard RC snubbers instead of active clamp circuits.
160°C maximum junction temperature	Permits higher ambient or case temperature operation than 125°C-rated alternatives, extending service life in enclosed converter cabinets.

Applications

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-power rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IXYS MDD4810-22	Same V_RRM (2200 V), lower I_FAVM (4500 A @ 100°C), higher R_thJC (0.0095 °C/W), requires 50–100 kN clamping force.	Suitable for lower-derating designs; less margin for sustained overload in traction applications.	Select when existing clamping hardware matches IXYS torque specs and thermal budget allows +1.2°C/W junction rise.
Powerex CM4810N22	Identical I_FAVM and V_RRM, but 10% higher v_F (1.59 V @ 10 kA); R_thJC = 0.0085 °C/W; Q_r ~20% higher at 2000 A.	Acceptable in UPS or battery charging where efficiency >98.5% is not mandatory; may require larger snubbers.	Prefer for cost-sensitive industrial OEMs where 0.14 V higher forward drop is acceptable and supply chain favors Powerex.

Compared with MDD4810-22 and CM4810N22, D4810N22TVFXPSA1 offers the lowest forward voltage and best thermal resistance-making it optimal for high-efficiency, high-reliability traction and heavy industrial rectifiers where conduction loss and thermal margin are primary constraints.

FAQ

Is D4810N22TVFXPSA1 RoHS-compliant?

Yes-D4810N22TVFXPSA1 complies with EU RoHS Directive 2011/65/EU and its amendments. Lead content is restricted to ≤1000 ppm, and all six hazardous substances (Pb, Cd, Hg, Cr⁶⁺, PBB, PBDE) meet threshold limits. Certificate of Compliance is available upon request for batch-specific traceability.

What is the recommended clamping torque for D4810N22TVFXPSA1?

Clamping force-not torque-is specified: 42–95 kN total compressive load applied across both anode and cathode studs. Actual torque depends on stud thread size (M33×2), lubrication, and interface material. Typical dry-thread torque is 1200–1400 N·m; use calibrated hydraulic tensioning tools and verify force via strain gauges or load-indicating washers.

Can D4810N22TVFXPSA1 be used in parallel configurations?

Yes-but only with strict dynamic current sharing measures: matched devices (v_F within ±20 mV at 10 kA), symmetrical busbar layout, identical clamping force per unit, and individual RC snubbers. Parallel operation beyond two units requires active current balancing or derating per IEC 60747-6 Annex D guidelines.

Does this diode require gate triggering or external control signals?

No-D4810N22TVFXPSA1 is an uncontrolled rectifier diode with no gate terminal. Conduction begins automatically when anode voltage exceeds cathode voltage by >0.83 V (threshold voltage at T_vj = 160°C) and ceases when current falls below zero. It functions purely as a passive, bidirectional voltage-blocking, unidirectional current-conducting device.
