Zero-ohm jumpers are commonly used in a wide range of markets and end products. They make circuitry routing easier and simplify manufacturing. Jumper requirements for higher current levels frequently exceed the capability of general-purpose jumpers. The maximum current rating for thick film general-purpose jumpers is only 3 amps and high current thick film jumpers typically […]

Bidirectional TVS devices boast high peak pulse power dissipation
Vishay Intertechnology introduced three new series of 24 V surface-mount XClampR transient voltage suppressors (TVS) that offer high peak pulse power dissipation equivalent to the 7 kW of conventional TVS at 10/1000 μs in the SMC (DO-214AB) package and 10/10 000 μs in the DO-218AB. The bidirectional devices deliver high power density over a wide […]
350-V GaN transistor features max 80 mΩ on resistance, 26-A pulsed output
EPC announces the production release of the EPC2050, a 350 V GaN transistor with a maximum RDS(on) of 80 mΩ and a 26 A pulsed output current. The EPC2050 measures just 1.95 mm x 1.95 mm. This tiny size enables power solutions that occupy ten times less area than comparable silicon solutions. Applications benefiting from […]
