The recommended PCB footprint for the TPSMC26CA-VR is a standard SMC package footprint with a pad size of 2.5mm x 1.5mm and a pitch of 0.95mm. It's recommended to consult the Littelfuse application note AN9313 for more detailed information on PCB layout and design considerations.
To ensure proper soldering, it's recommended to follow the soldering profile recommended by Littelfuse, which is a peak temperature of 260°C for 10-15 seconds. Additionally, the PCB should be designed with a solder mask and a solder paste with a melting point of 183°C to prevent solder bridging and ensure reliable connections.
The TPSMC26CA-VR has a maximum surge current rating of 100A for 10/1000μs waveform, as per the IEC 61000-4-5 standard. This rating is based on the device's ability to withstand high current surges without failing or degrading its performance.
The TPSMC26CA-VR has an operating temperature range of -40°C to 150°C, making it suitable for high-temperature applications. However, it's essential to ensure that the device is properly derated for high-temperature operation to prevent thermal runaway and ensure reliable performance.
To select the correct TVS diode, consider factors such as the maximum voltage, current, and power requirements of your application. Additionally, consider the type of transient protection required (e.g., lightning, ESD, or power cross), and the desired response time and clamping voltage. Littelfuse provides a TVS diode selection guide to help engineers choose the right device for their specific application.
