Infineon Technologies TD162N16KOFHPSA2

Overview

TD162N16KOFHPSA2 from Semikron is a phase-control thyristor module with dual anti-parallel SCR configuration, 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). It delivers 1.41 V maximum on-state voltage at 500 A and 125°C junction temperature, and is designed for industrial AC power control in medium-power rectifier and phase-angle regulator applications.

For engineers reviewing the TD162N16KOFHPSA2 datasheet, TD162N16KOFHPSA2 pinout, TD162N16KOFHPSA2 application, or TD162N16KOFHPSA2 equivalent, key selection criteria include repetitive blocking voltage rating, thermal resistance (RthJC = 0.096 °C/W per arm), gate trigger parameters (IGT ≤ 150 mA, VGT ≤ 2 V), and TIM-compatible thermal interface performance.

Technical Context

This dual SCR module implements a press-pack, AlN-isolated, two-arm configuration optimized for forced-air or natural-cooled industrial AC line switching. Its 125°C maximum junction temperature and 0.096 °C/W junction-to-case thermal resistance per arm enable stable operation under high-conduction-angle sinusoidal loads.

The device features critical dv/dt capability of 1000 V/µs (6th letter F), di/dt rating of 150 A/µs, and commutated turn-off time (tq) of 200 µs - enabling reliable operation in B2 and B6 bridge topologies with inductive loads and controlled gate triggering.

Key Specifications

Pinout & Package

TD162N16KOFHPSA2 is housed in a press-pack, double-sided cooled, isolated module package with AlN ceramic insulation and M1/M2 screw terminals. The mechanical layout follows Semikron's standard dual-arm thyristor footprint (see datasheet page 3), featuring separate anode/cathode terminals per SCR arm and isolated gate control pins.

FAQ

What is the maximum allowable junction temperature for TD162N16KOFHPSA2?

The maximum junction temperature (Tvj max) is 125°C, as specified in the datasheet's thermal properties table. This limit must be maintained under all operating conditions, including worst-case conduction angles and ambient temperatures, using verified thermal modeling with RthJC = 0.096 °C/W per arm and measured case temperature.

Does TD162N16KOFHPSA2 require a thermal interface material (TIM)?

Yes - the "HPSA2" suffix explicitly denotes TIM-optimized packaging. With TIM, RthCH is reduced to 0.03 °C/W per module, whereas without TIM it rises to 0.06 °C/W. Using certified thermal paste or pad meeting Semikron's interface pressure and flatness requirements is mandatory to achieve rated thermal performance.

Can TD162N16KOFHPSA2 be used in single-phase applications?

Yes - while optimized for three-phase B6 bridges, it supports single-phase full-wave rectification and phase-control topologies. Each arm handles up to 162 A average current, and the dual anti-parallel structure allows bidirectional conduction essential for AC line control in single-phase dimmers and heaters.

What gate drive voltage and current are required to reliably trigger TD162N16KOFHPSA2?

At 25°C, gate trigger current (IGT) must exceed 150 mA and gate trigger voltage (VGT) must reach ≥2 V under 6 V anode-cathode voltage. For robust operation across temperature, designers should apply ≥250 mA peak gate current with ≥10 V pulse amplitude and ≥20 µs width, per Semikron's application note AN-1002.
