SMAJ15CA

The SMAJ15CA is a bidirectional TVS diode designed to protect sensitive electronic equipment from transient voltage events. It clamps high-voltage spikes to a safe level, thereby preventing damage to the components in the circuit. The device is packaged in a standard DO-214AC (SMA) package suitable for surface-mount technology (SMT).

Key Features:

• Bidirectional Protection: Protects against positive and negative voltage spikes.
• Peak Pulse Power Dissipation: Typically rated for 400 watts at a 10/1000 µs waveform, ensuring robust protection against transient events.
• Low Clamping Voltage: Provides effective clamping to a safe voltage level during a transient event.
• Fast Response Time: Responds almost instantaneously to transient overvoltages, ensuring protection of sensitive components.
• Surface-Mount Package: DO-214AC (SMA) package allows for easy integration into modern PCB designs.
• Stand-off Voltage: 15V, indicating the maximum continuous operating voltage.
• Breakdown Voltage: Typically around 16.7V to 18.5V.

Applications:

• Telecommunication Systems: Protects communication lines and devices from lightning and other transient events.
• Consumer Electronics: Provides protection for devices such as smartphones, tablets, and other portable electronics.
• Industrial Equipment: Used in industrial control systems and equipment to safeguard against voltage spikes.
• Automotive Electronics: Employed in automotive systems for protecting electronic control units and other sensitive components.
• Power Supplies: Protects power supply circuits from transient overvoltage conditions.
