Infineon Technologies TD330N16AOFHPSA1

Overview

TD330N16AOFHPSA1 from Infineon Technologies is a phase-control thyristor module designed for high-power AC line switching and rectification in industrial drive systems. It delivers 330 A average on-state current at 85°C case temperature, 1600 V repetitive peak off-state voltage, and features pressure-contact die attachment for thermal and mechanical robustness. It is used in soft starters, static switches, and UPS rectifiers where high surge immunity and reliable forced-commutation are required.

For engineers reviewing the TD330N16AOFHPSA1 datasheet, TD330N16AOFHPSA1 pinout, TD330N16AOFHPSA1 application, or TD330N16AOFHPSA1 equivalent, key selection criteria include junction-to-case thermal resistance (0.106 K/W), critical dv/dt rating (1000 V/µs), gate trigger current (≤200 mA), and insulated baseplate construction for safe mounting on heatsinks.

Technical Context

This thyristor module implements a dual-arm, press-pack structure with electrically isolated AlN ceramic baseplate and silicon dies mounted via pressure-contact technology-eliminating wire bonds and solder fatigue risks. Its 130°C maximum junction temperature and 12500 A non-repetitive surge rating support short-circuit tolerant operation in crowbar and motor control applications.

The device operates under phase-angle control with precise gate triggering (≤3 µs delay) and exhibits low conduction losses: threshold voltage ≤0.8 V and slope resistance ≤0.5 mΩ at 130°C. Its 1000 V/µs critical dv/dt and 250 A/µs di/dt capability enable stable commutation in high-frequency AC line applications without snubbers in many configurations.

Key Specifications

Pinout & Package

TD330N16AOFHPSA1 is housed in an industrial-standard press-pack module with electrically insulated AlN baseplate and five terminals: two main power terminals (anode/cathode per arm), two gate terminals (G1/K1 and G2/K2), and one common cathode connection. Mounting uses M1 (5 Nm) and M2 (12 Nm) torque specifications for mechanical and electrical interfaces respectively.

FAQ

What is the maximum allowable case temperature for continuous operation?

The TD330N16AOFHPSA1 supports continuous operation up to +130°C case temperature, as defined by its thermal derating curves. At TC = 85°C, it delivers its full 330 A ITAVM rating; above that, current must be linearly reduced per the published ITAVM vs. TC graph, reaching zero at 130°C.

Does this module require external snubber circuits?

Snubbers are not mandatory due to the device's high 1000 V/µs critical dv/dt rating and optimized gate structure. However, in highly inductive loads or long cable runs where voltage overshoot exceeds VDRM, an RC snubber across each arm is recommended to ensure long-term reliability and prevent false triggering.

How is gate drive isolation implemented in this module?

Each gate terminal (G1, G2) is galvanically isolated from the baseplate and power terminals. Gate-to-cathode isolation is rated to 3.6 kV RMS (1 sec), enabling direct connection to optocoupled or pulse-transformer-based gate drivers without additional isolation components in standard industrial control designs.

Can both arms be operated independently in single-phase applications?

Yes-Arm 1 (A1–K1) and Arm 2 (A2–K2) are fully independent, sharing only the insulated baseplate. They can be driven with separate gate signals for asymmetrical phase control, back-to-back switching, or redundancy schemes in critical single-phase power conditioning systems.
