Infineon Technologies IRAMS10UP60B

Overview

IRAMS10UP60B from Infineon Technologies (formerly International Rectifier) is a fully isolated 3-phase IGBT inverter hybrid IC with integrated gate drivers, bootstrap diodes, internal shunt resistor (33.3 mΩ), NTC thermistor, and protection circuitry-designed for AC motor drive in washing machines and refrigerators. It delivers 10 A RMS phase current at 600 V blocking voltage, supports 20 kHz PWM, and operates across –40°C to +150°C junction temperature.

For engineers reviewing the IRAMS10UP60B datasheet, IRAMS10UP60B pinout, IRAMS10UP60B application, or IRAMS10UP60B equivalent, key selection criteria include its integrated current sensing (ITRIP threshold 490 mV), matched propagation delay (≤75 ns), UL-recognized isolation (2000 VRMS), and plug-and-drive topology requiring only single-polarity 15 V logic supply.

Technical Context

The IRAMS10UP60B integrates six low-V_CE(on) non-punch-through IGBTs with anti-parallel diodes, three high-side gate drivers with embedded bootstrap diodes, and one low-side driver section-all housed in a single isolated PDIP-23 package. Its internal shunt enables direct current feedback without external sense amplifiers, while the integrated NTC thermistor (R₂₅ = 100 kΩ) provides real-time die temperature monitoring.

Protection features include under-voltage lockout on all channels (11.1 V ±0.2 V hysteresis), cross-conduction prevention logic, Schmitt-triggered inputs, and auto-reset overcurrent shutdown triggered by ITRIP (13.1–16.4 A bus current threshold). The module supports sinusoidal PWM up to 0.75 kW at 85–253 V_AC input with R_th(J-C) = 4.2 °C/W per IGBT.

FAQ

What is the maximum allowable DC bus voltage for IRAMS10UP60B?

The absolute maximum V_CE rating is 600 V, and the recommended operating V₊ is 450 V DC. Exceeding 450 V risks exceeding RBSOA limits during transients, especially at elevated junction temperatures. The module's short-circuit safe operating area is validated at V_P = 600 V, but continuous operation above 450 V requires derating per Figure 3 in the datasheet.

How does the internal shunt resistor interface with external current-sense amplifiers?

The shunt (33.3 mΩ) connects between the motor phase output (e.g., U) and the corresponding VS pin (e.g., VS1). Its differential voltage appears across VS1 and COM/ITRIP, allowing direct connection to an external op-amp or dedicated current-sense IC. The ITRIP pin accepts this voltage directly, with 490 mV triggering immediate fault shutdown.

Can IRAMS10UP60B operate with a 12 V logic supply instead of 15 V?

Yes-V_CC operates from 12 V to 20 V. At 12 V, gate drive strength decreases slightly, increasing V_CE(on) by ~5% and raising switching losses marginally. Undervoltage lockout activates below 10.6 V, so 12 V provides sufficient margin for stable operation with typical line regulation.

What thermal interface material is recommended for heatsink mounting?

A greased flat surface with thermal compound of ≥1 W/m·K conductivity is specified in the datasheet. Recommended materials include Dow Corning TC-5122 or Parker Chomerics THERM-A-GAP G30, applied at 0.1–0.15 mm thickness. Mounting torque must be 0.5–1.0 Nm on M3 screws to ensure optimal R_th(C-S) = 0.1 °C/W.
