Rectifiers meet next-gen battery charger efficiency targets
Enabling next-gen battery chargers to achieve efficiency and temperature targets, the Trench Super Barrier Rectifier (SBR) series has been launched by Diodes Incorporated. The 15A SBRT15U50SP5 and 20A SBRT20U50SLP rectifiers are the first in the series to be released by the company. While the former is suitable for 10W smartphone chargers, the latter suits 12.5W tablet chargers.
Due to the SBRs' low forward voltage, low leakage current and cooler running characteristics, they can cope with the shorter current pulses of 36kHz discontinuous mode charger designs.
The SBRT15’s features a forward voltage of 0.47V at 15A, while the SBRT20’s features that of 0.5V at 20A and both operate at +90ºC. The forward voltage and operating temperatures minimise conduction losses and increase charger efficiencies.
Blocking mode losses are also minimised by the rectifiers' low reverse leakage currents at high temperatures, which are 105mA in the SBRT15 and 100mA in the SBRT20 at +125ºC.
Featuring a voltage range spanning from 10 to 100V, the SBRs handle currents from 0.2 to 40A. The SBRT15 and SBRT20 are offered in Diodes’ PowerDI123, PowerDI5 and PowerDI5060 packaging options. Available in 3,000 unit quantities, the rectifiers are priced at $0.25 each.
