Silicon-controlled rectifier offers 1200V blocking voltage

The TN5050H-12WY is suitable for a wide range of AC/DC converter applications, including EV and other battery chargers, solar and wind renewable energy inverters, solid-state relays, UPSs and industrial welding systems.

The device reduces the BOM by offering superior surge-current handling, thermal-cooling capability, and overvoltage robustness, while uniquely enhancing reliability, quality and supply service with the AEC-Q101 compliance and the automotive PPAP certification. This allows designers to achieve the same levels of power and cooling efficiency as they could with traditional diode bridges, but with lower cost and smaller PCB footprint.

The thyristor handles up to 580A surge-current over the first 10ms and withstands surge- peak forward and reverse-blocking voltages as high as 1300V. Alongside an outstanding thermal-cooling capability, with junction-to-case thermal resistance of just 0.3°C/W at a junction temperature of 150°C, the TN5050H-12WY features a low on-state voltage drop of 1.55V at 100A. In addition, the device has a low off-state power consumption of 5µA at 1200V. The thyristor also features a high PCB creepage distance of more than 4mm, which greatly simplifies PCB layout in the application.

The TN5050H-12WY thyristor is available in volume production at a price of $4.73 for a volume of five units. The device is currently on display on the company’s booth, 551/9, at the PCIM trade show in Nuremberg, Germany.
