Ideal Power B-TRAN Bidirectional Switch & SymCool Modules

Ideal Power, Inc. is a Nasdaq-listed (IPWR) semiconductor company headquartered in Austin, Texas. It develops bidirectional power switches for power conversion and switching in electric vehicles, EV charging, renewable energy, energy storage, data centres, grids and industrial systems, protected by 94 issued patents at the start of 2025.

Its patented B-TRAN is a double-sided bipolar switch that natively blocks and conducts current in both directions with ultra-low conduction losses, replacing pairs of conventional transistors. Products include discrete B-TRAN devices, B-TRAN known good die for custom packaging, SymCool double-sided cooled power modules, SymCool IQ intelligent modules, evaluation boards and drivers. Main uses are solid-state circuit breakers, static transfer switches, EV contactors and battery disconnect units, including protection for 800 V DC AI data centres.

• B-TRAN switch: patented bipolar bidirectional switch with native two-way blocking and conduction.
• SymCool modules: double-sided cooled bidirectional power modules for medium and high currents.
• SymCool IQ: intelligent power modules for energy storage, EV charging and data centres.
• Known good die: bare B-TRAN die for custom module development.
• SSCB evaluation board: reference platform for solid-state circuit breakers.
• Drivers: gate driver boards matched to B-TRAN devices.

A Vietnamese switchgear maker can develop solid-state DC breakers for solar and battery storage systems. A data centre operator can evaluate B-TRAN-based protection for high-voltage DC power distribution. An EV or e-bus maker can test solid-state battery disconnect units in place of mechanical contactors.

One bidirectional B-TRAN can replace back-to-back transistor pairs, lowering conduction losses and component count in AC switches and circuit breakers. Solid-state breakers built on B-TRAN switch electronically without mechanical contacts that wear out. Double-sided cooling in SymCool modules improves heat removal at medium and high current. Known good die lets module makers build custom packages.

Solid-state circuit protection is growing with 800 V DC data centres, battery storage and EV architectures that need fast, wear-free switching. Asian circuit protection manufacturers are already designing B-TRAN into breakers. Vietnam's expanding data centre, rooftop solar and storage installations create demand for compact DC protection devices.

Nasdaq-listed (IPWR), headquartered in Austin, Texas. Holds 94 issued and 53 pending patents as of February 2025. Its first solid-state circuit breaker design win is with a large circuit protection manufacturer in Asia, and it works with Stellantis and several global Tier 1 automotive suppliers on inverters and EV contactors. Has distributors covering Asia and Pacific.
