Teledyne e2v HiRel adds space-screened versions of 100V, 90A and 650V, 30A GaN HEMTs
Teledyne e2v HiRel Electronics of Milpitas, CA, USA (part of the Teledyne Defense Electronics Group that provides solutions, sub-systems and components to the space, transportation, defense and industrial markets) has added new space-screened versions of its 100V, 90A and 650V, 30A high-reliability gallium nitride high-electron-mobility transistors (GaN HEMTs).
The new parts TDG650E30BSP, TDG100E90BSP and TDG100E90TSP go through NASA Level 1 or ESA Class 1 screening flow and can be brought up to full Level 1 conformance with extra qualification testing, if desired. Typical applications include battery management, DC–DC converters, and space motor drives.
Two new 100V parts are available with both bottom-side- and top-side-cooled packaging. One new 650V 30A GaN-on-silicon power transistor is available in a bottom-side-cooled package. Each device is available with options for EAR99 or European sourcing.
Teledyne e2v HiRel’s GaN HEMTs feature single-wafer lot traceability, extended-temperature performance from –55°C to +125°C, and low-inductance, low-thermal-resistance packaging.

“Our customers have embraced the previous release of 650V space-screened devices, and we have expanded our portfolio to provide additional options,” says Mont Taylor, VP of business development. “These GaN HEMT products save customers time and money by providing standard devices without the need for additional screening,” he adds. “Our expanded catalog with standard burn-in make it easy for designers to utilize the latest in GaN in their designs.”
Gallium nitride devices have revolutionized power conversion in other industries and are now available in radiation-tolerant, plastic-encapsulated options that have undergone stringent reliability and electrical testing to help ensure mission-critical success. The release of the new GaN HEMTs is said to deliver the efficiency, size and power density benefits required in critical aerospace & defense power applications.
Shipped from the firm’s DoD Trusted Facility in Milpitas, all three of the new devices are now available for ordering and immediate purchase from Teledyne e2v HiRel or an authorized distributor.
