Infineon Technologies IRAMS12UP60A

Overview

IRAMS12UP60A from Infineon Technologies (formerly International Rectifier) is a 12A, 600V integrated power hybrid IC with open-emitter pins, designed as a 3-phase inverter for appliance motor drives. It integrates trench IGBTs, high-voltage gate drivers, bootstrap diodes, temperature monitoring, and over-current protection in a single isolated SLLIMM™-nano package. Key confirmed specs: 600V V_CE(sus), 12A RMS phase current at 25°C, 2000V_RMS isolation, CTI >600, and 20kHz max PWM frequency - deployed in energy-efficient washing machine and refrigerator compressor drivers.

For engineers reviewing the IRAMS12UP60A datasheet, IRAMS12UP60A pinout, IRAMS12UP60A application, or IRAMS12UP60A equivalent, this page delivers verified electrical parameters, thermal resistance values (R_th(J-C) = 4.7°C/W per IGBT), propagation delay matching (±75ns), ITRIP threshold (4.3V typ), and isolation compliance - all critical for inverter layout, thermal design, and functional safety validation in white-goods motor control.

Technical Context

The IRAMS12UP60A implements a fully integrated 3-phase bridge using six trench IGBTs with matched V_CE(on) (1.85V typ @ 6A, 150°C) and fast recovery freewheeling diodes. Its driver core features Schmitt-triggered inputs, internal 290ns dead time, and cross-conduction prevention logic to ensure safe commutation under variable load conditions.

Thermal management is enabled by an embedded NTC thermistor (R₂₅ = 100kΩ ±3%, B = 4250K) and low R_th(J-C) packaging. Protection functions include under-voltage lockout on all supplies (10.9V hysteresis), ITRIP-based shutdown (4.3V threshold, 150ns blanking), and short-circuit rated IGBTs (5μs SCSOA at 400V).

FAQ

What is the maximum allowable DC bus voltage for IRAMS12UP60A?

The absolute maximum V₊ (positive bus input) rating is 450 V, as specified in the Absolute Maximum Ratings table. Operation above this voltage risks permanent damage to the IGBTs and internal driver circuitry. Designers must maintain margin below 450 V to accommodate transient overvoltages and ripple - typical recommended operating V₊ is ≤400 V for long-term reliability.

How does the T/ITRIP pin function in dual-mode operation?

The T/ITRIP pin serves two distinct roles: as an analog output for the integrated NTC thermistor (R₂₅ = 100 kΩ), and as a digital over-current trip input with 4.3 V threshold and 0.15 V hysteresis. External circuitry must separate these functions - e.g., using a series RC filter to extract temperature while preserving fast fault response, per Figure 2 in the datasheet.

Can IRAMS12UP60A be used without external bootstrap capacitors?

No - external bootstrap capacitors (typically 0.22–0.47 µF ceramic) are mandatory between each VBx and VSx pin. The internal bootstrap diodes only provide charging path; they do not store energy. Omitting external capacitors causes gate drive collapse during high-side conduction, leading to IGBT failure due to insufficient V_GE.

What is the thermal resistance from junction to case for the freewheeling diodes?

The R_th(J-C) for each freewheeling diode is 5.8–6.9 °C/W, as specified in the Thermal and Mechanical Characteristics table. This value is measured separately from the IGBT R_th(J-C) (4.7–5.2 °C/W) and must be used in thermal modeling when calculating diode junction temperature under regenerative braking or high-reactive-load conditions.
