STMicroelectronics introduces the SMAJ8.5CA-TR, a robust transient voltage suppressor (TVS) diode designed to protect sensitive electronic equipment from voltage transients induced by system load dump and other transient voltage events. This TVS diode is a bidirectional device, providing symmetrical protection in AC lines or against reverse polarity in DC applications.

Key Features

• Stand-off Voltage: The SMAJ8.5CA-TR has a stand-off voltage of 8.5V, making it ideal for a range of applications that require this level of protection.
• Peak Pulse Power: It offers a peak pulse power dissipation of 400W (10/1000μs waveform), ensuring reliable protection against high energy transients.
• Clamping Voltage: With a clamping voltage of 14.4V, this device can effectively clamp transient overvoltages, preventing damage to the protected component.
• Low Leakage Current: The low leakage current of the diode minimizes power loss and ensures energy efficiency in standby mode.
• Fast Response Time: The SMAJ8.5CA-TR boasts a fast response time to transient events, typically in the order of picoseconds, providing immediate protection to the system.
• Package: Supplied in an SMA (DO-214AC) package, the device is compact and suitable for automated assembly processes, saving time and cost in manufacturing.
