Teledyne e2v HiRel Electronics has released the TDGM650LS60 GaN load switch with integrated isolated driver, the first product in its innovative new 650-V power module family. This new module utilizes a Teledyne high voltage GaN transistor and integrates an isolated driver in one package.

Designed to serve as a load switch or solid-state switch, the TDGM650LS60 offers unparalleled performance and versatility. With the driver providing 5 kV isolation and a GaN transistor boasting a minimum breakdown voltage of 650-V, this module ensures robust and dependable operation in diverse environments.

One of the standout features of the TDGM650LS60 650-V GaN load switch is its lightning-fast switching time coupled with the absence of moving parts. This unique combination not only enhances operational efficiency but also significantly elevates the reliability of the device. As a result, the TDGM650LS60 is ideally suited for high-reliability applications, including but not limited to Space, Avionics, and Military sectors.

The GaN load switch is designed for applications with high voltage and high current demand. It achieves stable 25-mΩ RDSon and can withstand Vds voltage to 650 V. The TDGM650LS60 can be switched on and off either with the PWM input or the enable pin set to “high”. The device withstands a maximum current of 60 A.

“This launch marks a significant milestone in Teledyne’s commitment to innovation,” said Mont Taylor, Vice President and Business Development Manager at Teledyne e2v HiRel. “The TDGM650LS60 represents the culmination of our dedication to pushing the boundaries of technology, offering our customers performance, reliability, and versatility in their applications.”
