SEMITRANS®3+

For decades, the 62 mm SEMITRANS platform has been a trusted foundation for industrial power converters around the world. SEMITRANS 3+ builds on this proven legacy with a complete internal redesign that delivers higher power density, improved efficiency, and enhanced support for next-generation converter topologies – all while maintaining the familiar mechanical footprint of the classic SEMITRANS 3 package.

Proven Package, Next-Level Performance

Designed for today's demanding applications, SEMITRANS 3+ provides a seamless upgrade path for existing systems, enabling performance improvements without requiring changes to established mechanical interfaces or busbar designs.

The Evolution of an Industry Standard

SEMITRANS 3+ retains the well-known 62 mm housing dimensions and external interfaces that have made SEMITRANS 3 one of the most widely adopted power module platforms in the industry. Behind the familiar package, however, lies a thoroughly optimized internal design engineered for modern power electronics requirements.

Key benefits include:

Increased operating temperature, Tj,op = 175°C
Extended power range up to ICnom = 1000A
High-current power terminals
Higher power cycling capability
Humidity robustness
Features our new CAL7 diodes

Optimized for 3-Level Converters

As efficiency requirements continue to increase, three-level topologies such as T-Type Neutral Point Clamped (TNPC) converters are becoming the preferred architecture in applications including UPS systems, renewable energy converters, and modern motor drives.

SEMITRANS 3+ has been specifically optimized to support these advanced converter designs, enabling higher output power and improved system performance while helping designers reduce complexity and footprint.

Easy Upgrade Path

One of the greatest advantages of SEMITRANS 3+ is its compatibility with existing converter designs. By preserving the external appearance and interface of the classic SEMITRANS 3 platform, customers can benefit from the latest module technology while minimizing redesign effort and qualification costs.

This allows manufacturers to:

Upgrade performance with minimal design changes
Accelerate time-to-market
Simplify platform modernization
Maintain existing mechanical and electrical integration concepts

Typical Applications

SEMITRANS 3+ is an ideal solution for medium- and high-power industrial converters, including:

Uninterruptible Power Supplies (UPS)
Data Center power systems
Industrial motor drives
Wind energy converters
Solar and Energy storage systems
Industrial power supplies
