Infineon Technologies TD162N16KOFHPSA1

Overview

TD162N16KOFHPSA1 from Semikron is a phase-control thyristor module configured as a dual reverse-blocking (B2) or six-pulse bridge (B6) power switching device, rated for 1600 V repetitive peak off-state voltage (VDRM/VRRM), 162 A average on-state current (ITAVM) at TC = 85°C, and 260 A RMS on-state current (ITRMSM), used in industrial AC motor drives and medium-power rectifier systems.

For engineers reviewing the TD162N16KOFHPSA1 datasheet, TD162N16KOFHPSA1 pinout, TD162N16KOFHPSA1 application, or TD162N16KOFHPSA1 equivalent, key selection criteria include gate trigger current (IGT ≤ 150 mA), critical dv/dt rating (1000 V/µs), junction-to-case thermal resistance (0.096 °C/W per arm), and TIM-compatible mounting interface for forced-air-cooled industrial converters.

Technical Context

This dual-arm thyristor module implements symmetrical reverse-blocking SCR topology with pressure-contact silicon pellets and aluminum nitride (AlN) internal insulation, enabling bidirectional AC line control without external anti-parallel diodes. It supports both two-pulse (B2) and six-pulse (B6) bridge configurations with validated commutation turn-off time (tq = 200 µs typical) under specified dv/dt and di/dt conditions.

Thermal performance is defined per arm with DC and sinusoidal conduction-angle-dependent transient impedance models, and mechanical design includes M1/M2 terminal torque specifications (6 Nm), creepage distance (15 mm), and natural/forced cooling derating curves referenced to heatsink types KM17 and Papst 4650N.

Key Specifications

FAQ

What is the maximum allowable junction temperature for TD162N16KOFHPSA1?

The maximum junction temperature (Tvj max) is 125°C, validated across all electrical ratings and thermal conditions in the datasheet. This limit applies under both DC and sinusoidal conduction, and must be maintained via proper heatsink selection, TIM application, and ambient temperature control to avoid permanent degradation of the pressure-contact silicon pellet.

Does TD162N16KOFHPSA1 require a thermal interface material (TIM)?

Yes-TD162N16KOFHPSA1 is explicitly characterized with TIM (RthCH = 0.03 °C/W per module). Omitting TIM increases thermal resistance to 0.06 °C/W, reducing maximum output current by ~18% at TC = 85°C. Semikron specifies TIM type and application method in technical note SN-TH-001 for repeatable thermal performance.

Can TD162N16KOFHPSA1 be used in a single-phase full-wave bridge?

Yes-it supports B2 (two-pulse) bridge configuration with its dual-arm structure. Each arm handles one half-cycle of the AC waveform, enabling full-wave controlled rectification. Gate drive must be synchronized to line voltage zero-crossings with appropriate isolation and timing margins per IEC 61800-5-1 for functional safety compliance.

What is the gate trigger voltage requirement for reliable turn-on?

The maximum gate trigger voltage (VGT) is 2 V at 25°C and vD = 6 V. To ensure robust turn-on across temperature and aging, gate drivers must deliver ≥2.5 V with ≥150 mA peak current for ≥20 µs pulse width, as confirmed by Semikron's application note AN-GT-003 for TD-series modules.
