Infineon Technologies TD210N12KOFHPSA1

Overview

TD210N12KOFHPSA1 from Infineon Technologies is a phase-control thyristor module rated for 1200 V repetitive peak off-state voltage (VDRM/VRRM), 210 A average on-state current at TC = 85 °C, and 6600 A non-repetitive surge current (ITSM). It employs pressure-contact silicon pellet technology with electrically insulated baseplate, and is designed for high-reliability power control in industrial AC line-commutated applications such as soft starters and static switches.

For engineers reviewing the TD210N12KOFHPSA1 datasheet, TD210N12KOFHPSA1 pinout, TD210N12KOFHPSA1 application, or TD210N12KOFHPSA1 equivalent, key selection criteria include verified VDRM/VRRM rating, ITAVM derating vs. case temperature, RthJC thermal resistance, gate trigger characteristics (IGT ≤ 200 mA, VGT ≤ 2 V), and mechanical mounting torque specifications (M1: 5 Nm).

Technical Context

This dual-thyristor module operates in line-commutated mode with a maximum junction temperature of 125 °C and a critical rate of rise of off-state voltage (dv/dt)cr of 1000 V/µs. Its pressure-contact construction eliminates wire bonds and enables robust thermal performance with RthJC ≤ 0.124 K/W per arm under DC conditions.

The device features a 17 mm creepage distance, basic insulation per IEC61140 Class 1, and gate-controlled turn-on with latching current IL ≤ 1200 mA and holding current IH ≤ 300 mA. Freewheeling time tq is typ. 200 µs under specified commutation conditions (vRM = 100 V, dvD/dt = 20 V/µs).

Key Specifications

Pinout & Package

TD210N12KOFHPSA1 is housed in an industrial-standard pressure-contact module with electrically insulated AlN ceramic baseplate (Class 1 insulation), 50 mm baseplate width, and M1 (5 Nm) mechanical mounting points. Terminal connections use M2 screws (12 Nm torque) for main current paths and DIN 46244 A-style control terminals (2.8 × 0.8 mm).

FAQ

What is the maximum allowable case temperature for continuous operation?

The maximum case temperature (TC) is not explicitly defined as a standalone limit; instead, the device is rated for ITAVM = 210 A at TC = 85 °C. Derating curves show that at TC = 73 °C, ITAVM rises to 261 A. Operation beyond TC = 85 °C requires junction temperature monitoring to ensure Tvj ≤ 125 °C, using RthJC = 0.124 K/W and measured case temperature.

Does TD210N12KOFHPSA1 support forced-air or liquid cooling?

Yes - the module's RthCH (case-to-heatsink) is ≤ 0.04 K/W per arm, making it compatible with both forced-air and liquid-cooled heatsinks. Performance data in the datasheet includes derating curves for sinusoidal and rectangular current waveforms across multiple conduction angles, confirming suitability for active thermal management in high-power drives and UPS systems.

Can this module be used in anti-parallel configuration for AC switching?

Yes - TD210N12KOFHPSA1 contains two independent thyristor arms (A1/K1 and A2/K2) with isolated gates, enabling true anti-parallel connection for bidirectional AC phase control. Gate drive circuits must provide synchronized, polarity-correct pulses to each G/K pair, respecting the 3 µs max gate delay (tgd) and 1200 mA latching current requirement.

What is the recommended gate drive circuit topology?

A pulse-transformer-based gate driver is recommended to maintain galvanic isolation between control logic and main terminals. The datasheet specifies IGT ≤ 200 mA and VGT ≤ 2 V at 25 °C, with minimum iGM = 1 A and diG/dt ≥ 1 A/µs for reliable turn-on. Peak gate power limits (e.g., 150 W for 0.1 ms) constrain pulse width and repetition rate in high-frequency phase control.
