This document describes the features and characteristics of the SPA516 and SPA516L-3UF ultra-fast recovery dual single phase bridge assemblies produced by Solid State Devices, Inc. They feature ultra-fast recovery time, 3000V blocking voltage, 6000V dielectric voltage, 3A average output current, and low reverse leakage current.
The SPA516L-3UF bridge assembly from SSDI offers ultra‑fast recovery of 70 ns, a 3000 V blocking voltage and a 6000 V dielectric rating. It is designed for dual single‑phase operation and features glass‑passivated rectifiers, hermetically sealed discretes, and an aluminum base for high thermal conductivity.
Key electrical characteristics include an average output current of 3 A, a forward voltage drop of 5.70 V at 3 A, a reverse leakage current of 10 pA at 25 °C, and an isolation resistance of 1.0 GΩ. The device operates from –55 °C to +150 °C and has a maximum thermal resistance of 1.125 °C/W from junction to case.
