SM6T150CA Description

Short technical summary and product information.

The SM6T150CA from STMicroelectronics is a surface-mount Transient Voltage Suppressor (TVS) diode. It is designed to protect sensitive electronic equipment against electrostatic discharges (ESD) and electrical overstress.

This bidirectional TVS diode features a peak pulse power rating of 600W for a 10/1000 μs waveform and 4kW for an 8/20 μs waveform. It offers a wide stand-off voltage range from 5V to 188V, with a specific breakdown voltage of 128V. The device exhibits low leakage current, with a maximum of 0.2 μA at 25°C and 1 μA at 85°C.

The SM6T150CA has a maximum operating junction temperature of 150°C and can handle high power capabilities up to 350W at Tj max for a 10/1000 µs pulse. It is constructed with glass passivated die and housed in a molded plastic SMB (DO-214AA) package, suitable for surface mounting.

This TVS diode is compliant with IEC 61000-4-2 for ESD protection and MIL STD 883, method 3015. Its fast response time and excellent clamping capability make it suitable for various protection applications in electronic circuits.
