:The SMAJ85CA-TR is an automotive-grade Transient Voltage Suppressor (TVS) diode made by STMicroelectronics. The device is designed to provide protection from voltage spikes and transients in applications requiring 400W of power. It has a breakdown voltage rating of 85V, and is bidirectional, meaning it can handle spikes in both directions. The device is compliant with AEC-Q101 automotive standard, making it suitable for use in a variety of automotive electronic systems. The SMAJ85CA-TR has a maximum peak Power Dissipation rating of 400W, and is capable of handling surge currents up to 44A. It also features an integrated circuit latch-up rating of 50A. The device is available in standard SMAJ packages, and is RoHS compliant.
