Infineon Technologies TD60N16SOFHPSA1

Overview

TD60N16SOFHPSA1 from Infineon Technologies is a phase-control thyristor module designed for high-power AC line switching and rectification in industrial drive systems. It features 1600 V repetitive peak off-state voltage (VDRM/VRRM), 55 A average on-state current at TC = 85 °C, 1500 A non-repetitive surge current (ITSM), and electrically insulated baseplate construction for safe mounting on heatsinks. It is used in soft starters and static switches where precise conduction-angle control and thermal robustness are required.

For engineers reviewing the TD60N16SOFHPSA1 datasheet, TD60N16SOFHPSA1 pinout, TD60N16SOFHPSA1 application, or TD60N16SOFHPSA1 equivalent, key selection criteria include junction-to-case thermal resistance (0.47 K/W), gate trigger current (≤100 mA), critical dv/dt rating (1000 V/µs), and isolation test voltage (3.6 kV for 1 sec).

Technical Context

This dual-thyristor module operates in phase-controlled AC circuits using gate-triggered turn-on with zero-crossing or angle-controlled firing. Its 130 °C maximum junction temperature and 0.47 K/W RthJC enable stable operation under high RMS load currents up to 90 A (ITRMSM) when properly heatsinked.

The module integrates two anti-parallel thyristors per arm in an industrial-standard solder-solder package with Al₂O₃-based electrical insulation. Its 170 µs typical commutated turn-off time (tq) and 140 A/µs critical di/dt support controlled commutation in bridge rectifiers and power controllers.

Key Specifications

Pinout & Package

FAQ

What is the maximum allowable case temperature for continuous operation?

The maximum case temperature (TC) is +125 °C, verified per datasheet Figure 7. At this temperature, the device supports up to 55 A average on-state current (ITAVM) with 180° conduction angle under DC or sinusoidal loading. Exceeding this limit risks accelerated parameter drift and reduced lifetime due to thermal overstress.

Can TD60N16SOFHPSA1 be used in a single-phase full-wave bridge?

Yes-it is configured as a dual-thyristor module with independent A1/K1/G1 and A2/K2/G2 terminals, enabling direct implementation in single-phase B2 bridges. Each arm handles one half-cycle; gate timing must be synchronized to AC zero-crossing with appropriate delay for desired conduction angle.

What gate drive requirements ensure reliable turn-on at full blocking voltage?

A minimum gate trigger current of 100 mA (IGT max) and voltage of 2.5 V (VGT max) must be delivered with di/dt ≥1 A/µs and pulse width ≥20 µs. For robust operation at 1600 V VDRM, a 1 A, 50 µs gate pulse with 10 Ω series resistance is recommended to overcome threshold variation at elevated junction temperatures.

How does the insulated baseplate affect heatsink mounting?

The Al₂O₃-insulated baseplate allows direct mounting to grounded metal heatsinks without additional insulating washers or pads. Thermal interface material (e.g., silicone grease or phase-change pad) must still be applied between baseplate and heatsink to minimize RthCH (max 0.11 K/W per module), but electrical isolation is maintained inherently.
