The performance of a 9 device array of 500 × 500 μm2 GaN p-i-n rectifiers fabricated on epitaxial layers grown on a free-standing GaN template is reported. The forward turn-on voltage was ∼ 5.5 V at 25 °C, with an on-state resistance of ∼ 5 × 10-3 Ωcm2. The total forward current was 1 A at ∼ 8.8 V and 2.6 A at 18 V. The power figure-of-merit for the array, VB 2/RON, was 0.69 MWcm-2, with a reverse recovery time of ≤300 ns. The individual p-i-n rectifiers were interconnected using electroplated Au and clamped in a Cu pressure pack for thermal management.
