The SMDJ85CA is an unidirectional Transient Voltage Suppressor (TVS) produced by Yageo. It is designed to safeguard sensitive components in a circuit from overvoltage and/or reverse voltage transients. The device is a surface mount, singleeline chip capacitors in a DO-214AB (SMC) package with RoHS compliance. The SMDJ85CA has a maximum withstand voltage of 21.9A 137V 94.4V 85V, with low standby power consumption, low clipping voltages, and an operating temperature range of -40°C to +125°C. It is designed with a low capacitance and a low capacitance variation. In addition, it has positive temperature coefficients, an integration level of 0.33pF, and shutdown support at 0V or 2.7V. This device is ideal for applications including automotive and A/V equipment, industrial control, consumer electronics, and medical devices.
