Infineon Technologies TT162N16KOFKHPSA1

Overview

TT162N16KOFKHPSA1 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 features AlN ceramic isolation, pressure-contact silicon die, and is designed for industrial AC power control in medium-power rectifier and motor drive systems.

For engineers reviewing the TT162N16KOFKHPSA1 datasheet, TT162N16KOFKHPSA1 pinout, TT162N16KOFKHPSA1 application, or TT162N16KOFKHPSA1 equivalent, key selection criteria include commutated turn-off time (tq = 200 µs), critical dv/dt rating (1000 V/µs), thermal resistance (RthJC = 0.096 °C/W per arm), gate trigger current (IGT ≤ 150 mA), and isolation test voltage (3.0 kV RMS).

Technical Context

This thyristor module implements a two-arm, anti-parallel SCR topology for bidirectional AC phase control. It supports forced-air or natural cooling with specified transient thermal impedance models (ZthJC, ZthCA) for both sinusoidal and rectangular conduction angles.

Gate triggering follows IEC 747-6 standards with defined latching (IL ≤ 800 mA) and holding (IH ≤ 200 mA) currents. The device uses AlN (aluminum nitride) as internal insulation and requires TIM (thermal interface material) for optimal heatsink coupling, with validated RthCH = 0.03 °C/W per module when used.

FAQ

What is the maximum allowable junction temperature for TT162N16KOFKHPSA1?

The maximum junction temperature (Tvj max) is 125°C, as specified in the datasheet's thermal properties table. This limit applies under all operating conditions and must be maintained via proper heatsinking and thermal interface design to ensure long-term reliability and prevent thermal runaway during surge events.

Does TT162N16KOFKHPSA1 require external snubber circuits?

Yes - due to its high critical dv/dt rating (1000 V/µs), external RC snubbers are recommended for inductive loads to suppress voltage transients exceeding this threshold. Snubber values must be calculated based on load inductance, switching frequency, and expected di/dt, per IEC 61800-5-1 guidelines.

Can TT162N16KOFKHPSA1 be used in parallel configurations?

No - the module is not characterized or guaranteed for parallel operation. Its pressure-contact die architecture and gate threshold matching are optimized for single-module use. Parallel connection would risk current imbalance and thermal runaway without individual current-sharing reactors and matched gate drive timing.

What torque values are required for electrical and mechanical terminals?

Mechanical mounting torque (M1 screws) is 6 Nm ±15%; electrical terminal torque (M2 screws) is also 6 Nm ±10%. These values ensure reliable thermal contact and low-resistance power connections while preventing thread damage or baseplate deformation per Semikron's mechanical specifications.
