The recommended footprint and land pattern for the 1.5SMC220CA can be found in the Littelfuse application note AN9313, which provides guidelines for surface mount assembly of TVS diodes.
To ensure proper soldering and reliability, follow the soldering guidelines outlined in the Littelfuse application note AN9313, and ensure that the soldering process meets the requirements of IPC-A-610.
The maximum operating temperature range for the 1.5SMC220CA is -65°C to 150°C, as specified in the datasheet. However, it's recommended to derate the device's power handling capability at higher temperatures to ensure reliability.
While the 1.5SMC220CA is primarily designed for transient voltage suppression, it can be used in high-frequency applications up to 1 GHz. However, the device's parasitic capacitance and inductance should be considered in the design, and simulation or testing may be necessary to ensure the device meets the specific application requirements.
To select the correct TVS diode, consider the following factors: working voltage, peak pulse current, clamping voltage, and response time. The 1.5SMC220CA is suitable for applications requiring a standoff voltage of 220V and a peak pulse current of 1500W. Consult the Littelfuse TVS diode selection guide for more information.
