Description
What It Is
An IGBT module combines two IGBTs (insulated‑gate bipolar transistors) and associated diodes in a single package. IGBTs are high‑efficiency electronic switches widely used in power electronics because they offer fast switching, high voltage and current handling, and relatively low conduction losses.
📦 Typical Specifications (U‑Series Module)
While the exact “‑120” variant datasheet isn’t always published publicly online, the U2B family modules share common design traits. Based on closely related datasheets (e.g., the ‑060 versions) the characteristics typically include:
-
Voltage rating: ~600 V (for ‑060 family; ‑120 indicates ~1200 V class for higher voltage variants)
-
Collector current: ~300 A continuous
-
IGBT structure: N‑channel IGBTs with integrated free‑wheeling diodes
-
Fast switching capability: designed for efficient operation in converters and drives
-
Typical gate voltage: ±20 V
-
Operating junction temperature: up to ~150 °C
-
Isolation voltage: ~2500 VAC between terminals and baseplate
For the ‑120 suffix version, the collector‑emitter voltage rating is typically 1200 V, keeping other parameters (current, switching) similar to the 600 V variant. This makes it suitable for higher‑voltage power systems.
⚙️ Typical Applications
IGBT modules like this are used in medium‑ to high‑power electronics, including:
-
Motor drives and inverters (e.g., industrial motor controllers)
-
Uninterruptible power supplies (UPS)
-
AC and DC servo drives
-
Renewable energy inverters (solar, battery systems)
