The TN5050H-12WY is intended for a range of AC/DC converter applications, including EV (Electric Vehicle) and other battery chargers, solar and wind renewable energy inverters, solid-state relays, Uninterruptible Power Supplies, and industrial welding systems. The device reduces the bill of materials by offering superior surge-current handling, thermal-cooling capability, and overvoltage robustness, while enhancing reliability, quality, and supply service with the AEC-Q101 compliance and the automotive PPAP (Production Part Approval Process) certification.
This allows designers to achieve the same levels of power and cooling efficiency as they could with traditional diode bridges, and with lower cost and smaller PCB footprint.
Features of the TN5050H-12WY include:
Surge-current handling (up to 580A over the first 10 msec);
High surge-voltage robustness – the device can withstand maximum surge- peak forward and reverse-blocking voltages as high as 1300V;
Excellent thermal-cooling capability, with junction-to-case thermal resistance of 0.3 °C/W at a junction temperature of 150°C;
Low on-state voltage drop of 1.55V(maximum voltage)@ 100A (Tj=25 °C);
Low off-state power consumption of 5 µA max @1200V (Tj=25 °C);
A high PCB creepage distance of more than 4mm, which greatly simplifies PCB layout in the application.
The TN5050H-12WY thyristor costs $4.73 in low volume.
