Infineon Technologies IRAMX20UP60A-2

Overview

IRAMX20UP60A-2 from Infineon Technologies (formerly International Rectifier) is a 20A, 600V integrated power hybrid IC for 3-phase AC motor drives in air conditioning compressors and light industrial inverters. It integrates six IGBTs with matched low V_CE(on) punch-through technology, three high-voltage gate drivers, under-voltage lockout per channel, cross-conduction prevention logic, and an internal NTC thermistor. Its SiP2 package delivers 2000V_RMS isolation and thermal enhancement via heatspreader.

For engineers reviewing the IRAMX20UP60A-2 datasheet, IRAMX20UP60A-2 pinout, IRAMX20UP60A-2 application, or IRAMX20UP60A-2 equivalent, key selection criteria include RMS phase current rating (20A @ T_C=25°C), short-circuit safe operating area (10μs), matched propagation delay (≤75ns), bootstrap diode forward voltage (1.90–2.60V), and open-emitter topology enabling discrete current sensing.

Technical Context

This hybrid IC implements a fully isolated 3-phase inverter stage with integrated high-side and low-side gate drivers, each featuring Schmitt-triggered 5V logic inputs, programmable blanking on the T/ITRIP fault pin, and independent UVLO thresholds (10.6–11.6V). The driver IC uses matched propagation delays and built-in dead-time generation (220–360ns) to prevent shoot-through.

The power section employs punch-through IGBTs rated for 600V blocking and 35A pulsed RMS current, with integrated freewheeling diodes and temperature monitoring via a factory-calibrated 100kΩ NTC thermistor (B = 4250K). Isolation is achieved through transfer-molded SiP2 packaging with 3.2mm creepage distance and 2000V_RMS withstand rating.

FAQ

What is the maximum allowable DC bus voltage for IRAMX20UP60A-2?

The absolute maximum V+ rating is 450V DC, and the IGBTs are rated for 600V V_CES. Operation above 450V violates recommended conditions and risks premature failure due to overstress on internal bootstrap components and gate oxide reliability. Design margin should maintain V+ ≤ 400V for sustained 150°C junction operation.

Can IRAMX20UP60A-2 be used without an external heatsink?

No. With R_th(J-C) = 1.5–2.2°C/W per IGBT and 38W dissipation at T_C = 25°C, passive cooling is insufficient. A mechanically mounted aluminum heatsink (≥200cm², 10mm thick) with thermal compound is required to maintain T_J ≤ 150°C at 20A RMS. Derating to 10A RMS is mandatory above 60°C ambient without forced airflow.

How does the T/ITRIP pin function in overcurrent protection?

The T/ITRIP pin accepts either the internal NTC voltage divider output or an external fault signal. When voltage exceeds 4.75V (typical threshold), it triggers immediate shutdown of all six IGBTs within 1.75μs. A 100–150ns blanking window prevents false trips during PWM switching transients, and the post-trip clear time is 6.7–7.7ms at T_C = 100°C.

Is IRAMX20UP60A-2 compatible with 3.3V logic controllers?

No. The HIN/LIN inputs require 5V Schmitt-trigger logic with V_IL ≤ 0.8V and V_IH ≥ 3.0V. Direct connection to 3.3V microcontrollers will result in unreliable high-side activation and potential shoot-through. A level-shifting buffer (e.g., 74LVC1G17) is mandatory to ensure valid logic thresholds and noise immunity.
