Product details

Overview

D4201N20TXPSA1 from Infineon Technologies is a high-power, hermetically sealed ceramic press-pack rectifier diode designed for bidirectional heat sinking in industrial drive and crowbar circuits. It delivers 4240 A average forward current at TC = 100 °C, supports 2200 V repetitive peak reverse voltage, and withstands 88 kA surge current with 0.668 V threshold voltage and 0.083 mΩ slope resistance.

For engineers reviewing the D4201N20TXPSA1 datasheet, D4201N20TXPSA1 pinout, D4201N20TXPSA1 application, or D4201N20TXPSA1 equivalent, key selection criteria include junction-to-case thermal resistance (8.5 K/kW), clamping force range (36–52 kN), and reverse recovery charge (1.75 mAs at VR = 1000 V) under high-di/dt conditions.

Technical Context

This device employs a silicon pellet with pressure-contact construction and dual-sided cooling capability, enabling efficient thermal management in high-current DC link and short-circuit protection applications. Its hermetic ceramic package ensures long-term reliability under harsh industrial environments and eliminates solder joint failure modes associated with soldered packages.

The diode exhibits low conduction losses (v_F ≤ 1.00 V at 4000 A, T_vj = 160 °C) and controlled reverse recovery behavior (Q_r ≤ 1.75 mAs, I_RM ≤ 175 A), making it suitable for forced-commutated systems where switching transients must be tightly managed.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	2200 V - Maximum repetitive reverse blocking voltage at full operating temperature range.
I_FAVM	4240 A - Average forward current rating at case temperature of 100 °C, defining continuous DC conduction capacity.
I_FSM	88000 A - Peak non-repetitive surge current for 10 ms, supporting short-circuit fault handling in drives.
V_T0	0.668 V - Threshold voltage at maximum junction temperature, used to model on-state conduction loss.
r_T	0.083 mΩ - Slope resistance at T_vj max, determining linear portion of forward voltage drop vs. current.
R_thJC	8.5 K/kW - Junction-to-case thermal resistance under two-sided cooling, critical for heatsink sizing.
Q_r	1.75 mAs - Maximum recovered charge at VR = 1000 V, directly impacting snubber design and commutation stress.

Pinout & Package

Hermetically sealed ceramic press-pack housing with two metal terminals: Anode (Terminal 1) and Cathode (Terminal 2), requiring mechanical clamping between heatsinks. No soldering or leadframe; electrical connection via direct pressure contact.

Pin/Terminal	Circuit Role	Design Meaning
Anode (Terminal 1)	Forward current entry point	High-current input terminal; must be mounted to heatsink with specified clamping force (36–52 kN).
Cathode (Terminal 2)	Forward current exit point	High-current output terminal; forms DC link return path and enables bidirectional thermal conduction.

Key Features

Feature	Design Value
Full 50/60 Hz blocking over wide temperature range	Ensures stable AC line rectification across -40 °C to +160 °C ambient without derating.
High DC blocking stability	Maintains rated V_RRM under sustained DC reverse bias, critical for regenerative braking energy feedback.
High surge current capability	Withstands 88 kA for 10 ms, enabling use in crowbar circuits for motor drive overvoltage protection.
Hermetically sealed ceramic package	Eliminates moisture ingress and corrosion risk in humid or chemically aggressive industrial environments.
High case non-rupture current	Prevents mechanical fracture during extreme short-circuit events, preserving structural integrity under 52 kN clamping load.

FAQ

What is the recommended clamping force for D4201N20TXPSA1 installation?

The device requires a mechanical clamping force between 36 kN and 52 kN applied across its anode and cathode terminals to ensure optimal thermal contact and electrical conductivity. Under-torque risks increased thermal resistance and premature failure; over-torque may deform the ceramic housing or damage internal silicon contacts.

Does D4201N20TXPSA1 support single-sided cooling?

No-D4201N20TXPSA1 is optimized for two-sided cooling only. Its thermal resistance specification (R_thJC = 8.5 K/kW) assumes heatsinks mounted on both anode and cathode terminals. Single-sided operation increases R_thJC to 14.9–19.8 K/kW and is not recommended for continuous-rated loads.

How does reverse recovery performance affect snubber design?

With Q_r = 1.75 mAs and I_RM = 175 A at VR = 1000 V, the diode demands precise RC snubber tuning to absorb stored charge and limit voltage overshoot during turn-off. Undersized snubbers cause excessive dv/dt stress on adjacent thyristors or IGBTs in bridge configurations.

Can D4201N20TXPSA1 replace legacy 2000 V diodes in existing designs?

Yes-if the original design accommodates 2200 V V_RRM, 4240 A I_FAVM, and 8.5 K/kW R_thJC under two-sided cooling. Physical dimensions (Ø121 mm × 35 mm) and clamping interface must also match; no adapter or retooling is required if mechanical footprint aligns.
