Diodes offers super barrier rectifier optimized solid state MR16 LED retrofit lamp

Diodes introduces the SBRT3M40P1 Trench Super-Barrier Rectifier (SBR®), which is optimized for small form factor to provide low forward voltage drop while maintaining low reverse leakage current to meet solid-state lighting focused on 12V AC LED retrofit lamps ( The input bridge rectifier requirements in SSL) applications provide a more efficient and longer-lasting replacement for the popular MR16 halogen lamps.

This 40V rated trench SBR device operates at +125°C with a low reverse leakage current of only 1.2mA at 12V blocking voltage, providing thermal runaway in the high temperature environment of MR16 retrofit lamps immunity. Moreover, this device maximizes the efficiency and power density of a 1A bridge rectifier with a forward voltage drop of only 0.29V at a compact PowerDI®123 footprint of 6.75mm2.

To minimize forward loss, the SBRT3U40P1 device has a lower forward voltage drop of 0.25V at the expense of a reverse leakage current of 4mA and provides different forward and reverse leakage currents. Option to optimize the rectifier circuit based on the duty cycle requirements of the waveform and the operating temperature.

The 40V blocking voltage capability typically provides sufficient margin for a 12V AC input supply. However, if the line is poorly regulated, the SBRT3M60P1 and SBRT3U60P1 devices with 60V blocking voltage capability are at the expense of a slightly higher forward voltage drop of 0.34V and 0.28V, respectively. To provide extra margin.

While offering traditional SMA package options, the PowerDI123 package has a smaller footprint (reduced from 16mm2 to 6.75mm2) and a lower side height (from 2mm to <1mm) for space-critical applications such as MR16 bulb market transformation goals.

Low Voltage SWA Armored Cable

Low Voltage SWA Armored Cable, also known as Steel Wire Armored Cable, is a type of electrical cable that is used for the transmission of low voltage electrical power. It is commonly used in applications where the cable needs to be protected from mechanical damage, such as underground installations or in areas with high levels of physical stress.


The SWA Armored Cable consists of multiple conductors, usually made of copper or aluminum, which are insulated and then wrapped in a layer of steel wire armor. The steel wire armor provides protection against external forces, such as impact or crushing, and also acts as a grounding conductor.

The cable is typically designed for voltages up to 1000 volts and is available in various sizes and configurations to suit different applications. It is commonly used in industrial, commercial, and residential settings for power distribution, lighting, and control systems.

Some of the key features and benefits of Low Voltage SWA Armored Cable include:

  • Mechanical Protection: The steel wire armor provides excellent protection against physical damage, making it suitable for installations in harsh environments or areas with high levels of mechanical stress.
  • Electrical Protection: The armor also acts as a grounding conductor, providing protection against electrical faults and ensuring safe operation.
  • Durability: The cable is designed to withstand extreme temperatures, moisture, and UV exposure, making it suitable for both indoor and outdoor installations.
  • Easy Installation: The armored construction of the cable makes it easy to handle and install, reducing installation time and costs.
  • Versatility: The cable is available in various sizes and configurations, allowing for flexibility in design and installation.

Overall, Low Voltage SWA Armored Cable is a reliable and durable solution for low voltage power transmission, offering excellent mechanical and electrical protection. It is widely used in a range of applications and environments, providing a safe and efficient electrical system.
