Infineon Technologies TDB6HK240N16PBOSA1

Overview

TDB6HK240N16PBOSA1 from Infineon Technologies is a 1600 V, 240 A half-controlled B6-bridge IGBT module integrating six thyristors and six fast recovery diodes in EconoPACK™4 housing with PressFIT terminals, rated for 480 A peak current per switch leg, featuring integrated NTC temperature sensor and isolated copper baseplate - used in industrial UPS systems and motor drives requiring high-voltage AC/DC conversion.

For engineers reviewing the TDB6HK240N16PBOSA1 datasheet, TDB6HK240N16PBOSA1 pinout, TDB6HK240N16PBOSA1 application, or TDB6HK240N16PBOSA1 equivalent, this module delivers verified 1600 V blocking capability, 240 A RMS rectifier output current, 4 kV AC insulation rating, 0.009 K/W case-to-heatsink thermal resistance, and PressFIT-compatible mechanical mounting for high-reliability power conversion designs.

Technical Context

This module implements a half-controlled three-phase bridge topology with six reverse-blocking thyristors (1600 V, 140 A RMS/chip) and six anti-parallel fast recovery diodes (1600 V, 140 A RMS/diode), enabling phase-controlled rectification in high-power AC-DC conversion stages. Its dual-device integration eliminates external commutation components and supports gate-triggered turn-on with 100 mA typical trigger current and 2.0 V trigger voltage.

Thermal management is enabled by an isolated copper baseplate, 0.22 K/W (thyristor) and 0.30 K/W (diode) junction-to-case resistance, and a low 0.009 K/W total module case-to-heatsink resistance at 1 W/(m·K) interface conductivity. The integrated NTC thermistor (5.00 kΩ @ 25°C, B-value 3375–3433 K) provides real-time junction temperature monitoring with ±5% deviation at 100°C.

FAQ

What is the maximum allowable gate trigger voltage for TDB6HK240N16PBOSA1?

The maximum gate trigger voltage is 2.0 V at 25°C with 12 V gate supply, as specified in the thyristor section. Exceeding this value risks premature triggering or gate oxide stress. Gate non-trigger voltage is guaranteed ≤0.3 V at 130°C, ensuring noise immunity in high-temperature environments.

Does TDB6HK240N16PBOSA1 require external snubbers during operation?

No external snubbers are required due to its 1000 V/µs critical dv/dt rating and 20 nH internal stray inductance. The module's low-inductance layout and integrated diodes suppress voltage spikes during commutation, provided gate drive rise time exceeds 1 µs and gate resistor values follow Infineon Application Note AN2015-05.

How is the NTC thermistor calibrated in TDB6HK240N16PBOSA1?

The NTC has a nominal resistance of 5.00 kΩ at 25°C with B-values of 3375 K (25–50°C), 3411 K (50–75°C), and 3433 K (75–100°C), enabling piecewise-linear temperature calculation. Deviation is ±5% at 100°C, and maximum dissipation is limited to 20 mW to avoid self-heating errors above 0.1°C.

What is the recommended heatsink interface material for TDB6HK240N16PBOSA1?

Infineon specifies thermal interface material with 1 W/(m·K) conductivity for R_thCH = 0.009 K/W validation. Standard silicone-based thermal greases (e.g., Dow Corning TC-5122) or 50–100 µm phase-change pads meet this requirement. Avoid dry mounting or low-conductivity pastes, which increase thermal resistance by ≥30% and risk exceeding 130°C junction limit.
