Product details
Overview
TZ860N16KOFTIMHPSA1 from Infineon Technologies is a pressure-contact thyristor module designed for high-reliability phase-controlled rectification and power switching in industrial drive systems. It delivers 1600 V repetitive peak off-state voltage (VDRM/VRRM), 910 A average on-state current at TC = 85°C, and 46 kA non-repetitive surge current (ITSM) - enabling robust operation in UPS rectifiers and soft-starters under high thermal stress.
For engineers reviewing the TZ860N16KOFTIMHPSA1 datasheet, TZ860N16KOFTIMHPSA1 pinout, TZ860N16KOFTIMHPSA1 application, or TZ860N16KOFTIMHPSA1 equivalent, key selection criteria include junction-to-case thermal resistance (0.0376 K/W), pre-applied TIM integration, electrically insulated baseplate, and 125°C maximum junction temperature - all critical for thermal management in high-power static switch designs.
Technical Context
This dual-thyristor phase control module uses pressure-contact silicon pellet technology to eliminate wire bonds and solder joints, ensuring stable conduction under high di/dt (200 A/µs) and dv/dt (1000 V/µs) stresses. Its electrically insulated AlN-ceramic baseplate supports Class I safety isolation per IEC61140 and enables direct mounting onto heatsinks without additional insulation.
The module is rated for 1800 A RMS on-state current (ITRMSM) and features a low on-state slope resistance of 0.145 mΩ, resulting in predictable conduction losses across conduction angles from 30° to 180°. Its 240 µs circuit-commutated turn-off time (tq) and gate trigger parameters (IGT ≤ 250 mA, VGT ≤ 2 V) support reliable firing in line-synchronized AC power controllers.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TT920N16KOF | Higher ITAVM (920 A at TC = 85°C), identical VDRM/VRRM (1600 V), but no pre-applied TIM; RthJC = 0.0390 K/W. | Lacks integrated TIM, requiring manual thermal interface application; suitable where thermal interface process control is already established. | Select when TIM application is standardized in production and marginal thermal margin exists. |

FAQ
What is the function of the pre-applied TIM in TZ860N16KOFTIMHPSA1?
The pre-applied thermal interface material (TIM) is a factory-installed, cured elastomeric layer between the module's baseplate and internal heat-spreading structure. It reduces RthCH from 0.015 K/W to 0.012 K/W, eliminates manual TIM dispensing variability, and ensures consistent thermal performance across production batches without requiring rework or inspection.
Can TZ860N16KOFTIMHPSA1 be used in anti-parallel configuration for AC switching?
Yes - TZ860N16KOFTIMHPSA1 contains two fully independent thyristor arms (A1/K1 and A2/K2) with separate gates (G1/G2), enabling direct anti-parallel connection for bidirectional AC phase control. Each arm supports full 1600 V blocking and 910 A ITAVM, and the insulated baseplate prevents electrical coupling between arms.
What is the significance of the "HPSA1" suffix in the part number?
The "HPSA1" suffix denotes Infineon's internal revision and packaging code: "HP" indicates high-power press-pack construction, "SA" specifies the use of AlN ceramic baseplate with Class I isolation, and "1" identifies the first production release with pre-applied TIM and updated thermal characterization per Revision 3.5 (2025-10-22).
How does the pressure-contact technology improve reliability versus solder-bonded modules?
Pressure-contact technology eliminates thermomechanical stress points from solder joints and aluminum bond wires. Under thermal cycling (−40°C to +125°C), this architecture avoids intermetallic growth and fatigue cracking, extending lifetime beyond 10⁶ cycles - validated in Infineon's accelerated life testing for industrial drive applications.
