Infineon Technologies IRAMS06UP60B-2

Overview

IRAMS06UP60B-2 from Infineon Technologies (formerly International Rectifier) is a fully isolated 3-phase IGBT-based integrated power module for appliance motor drives, featuring 6A RMS phase current, 600V blocking voltage, internal shunt resistor (50 mΩ), integrated gate drivers with bootstrap diodes, and built-in temperature monitoring via NTC thermistor. It targets variable-frequency compressor drives in refrigerators/freezers and electronic fan controls in HVAC systems.

For engineers reviewing the IRAMS06UP60B-2 datasheet, IRAMS06UP60B-2 pinout, IRAMS06UP60B-2 application, or IRAMS06UP60B-2 equivalent, key selection considerations include its 2000 VRMS isolation rating, matched propagation delays (470 ns turn-on / 615 ns turn-off), overcurrent trip threshold (8.5–10.5 A), thermal shutdown capability, and single-polarity +15 V supply requirement for simplified system design.

Technical Context

The IRAMS06UP60B-2 integrates six IGBTs (three half-bridges), six freewheeling diodes, three high-side gate drivers with integrated bootstrap diodes, logic-level Schmitt-trigger inputs, cross-conduction prevention, and undervoltage lockout on all channels. Its non-punch-through IGBT technology delivers low V_CE(on) (1.45–1.85 V at 3 A, 25°C) and short-circuit safe operating area (10 µs at 150°C).

Current sensing uses an internal 50 mΩ shunt resistor with ITRIP comparator (threshold 0.44–0.54 V), while thermal monitoring relies on a factory-calibrated NTC thermistor (R₂₅ = 100 kΩ ±3%, B = 4250 K). Propagation delays are tightly matched across all six channels (±10 ns typical variation), enabling precise PWM timing in 3-phase sinusoidal or space-vector modulation.

Key Specifications

FAQ

What is the maximum allowable DC bus voltage for IRAMS06UP60B-2?

The absolute maximum V_CE rating is 600 V, but the recommended maximum continuous DC bus voltage is 450 V, as specified in the Absolute Maximum Ratings table. Operation above 450 V risks exceeding RBSOA limits under transient conditions and reduces short-circuit withstand time. Derating is required above T_C = 25°C per the thermal resistance data (R_th(J-C) = 6.5 °C/W for IGBTs).

How does the internal shunt resistor interface with the controller?

The 50 mΩ shunt connects between the low-side emitter and V−; its differential voltage appears at the ITRIP pin relative to VSS. The internal comparator triggers fault shutdown when voltage exceeds 0.44–0.54 V (corresponding to 8.8–10.8 A). For closed-loop current control, external amplification is required since ITRIP is comparator-only-not an analog output.

Can IRAMS06UP60B-2 operate with a 12 V logic supply instead of 15 V?

No-VCC must be 15 V ±10% (13.5–16.5 V) per the Recommended Operating Conditions. At 12 V, the undervoltage lockout (VCCUV+ = 10.9 V typ.) may not engage reliably, and gate drive strength degrades significantly, increasing V_CE(on) and switching losses. The driver IC is not characterized for stable operation below 13.5 V.

What thermal interface material is recommended for the case-mounting surface?

A greased flat surface with thermal compound conductivity ≥1 W/m·K is specified in the datasheet. Use non-silicone, electrically insulating grease (e.g., Dow Corning TC-5122) to maintain isolation integrity. Avoid silicone-based pastes that may migrate and compromise creepage distance. Mounting torque must be 0.8–1.0 Nm on M3 screws to ensure uniform pressure without cracking the molded case.
