Diodes Incorporated SMAJ20CA-13 TVS Diode

The SMAJ20CA-13 is a robust transient voltage suppressor (TVS) diode from Diodes Incorporated, designed to protect sensitive electronic equipment from voltage spikes and transients induced by lightning and other sudden voltage events. This TVS diode is a bidirectional device housed in a compact SMA package, which is ideal for automated placement in a variety of applications, including consumer electronics, automotive systems, and industrial equipment.

Key Features:

• Stand-Off Voltage: The SMAJ20CA-13 has a stand-off voltage of 20V, making it suitable for protecting circuits with a nominal operating voltage close to this level.
• Peak Pulse Power: It can handle peak pulse power dissipation of 400W for 10/1000μs waveform, ensuring reliable protection against high energy transients.
• Clamping Voltage: The device provides a clamping voltage of 32.4V, which is the maximum voltage that will appear across the device when subjected to a peak pulse current.
• Low Leakage Current: It features low leakage current, minimizing power loss when the device is in standby mode and enhancing the overall efficiency of the system it protects.
• Fast Response Time: With its fast response time, the SMAJ20CA-13 reacts quickly to transient over-voltage events, providing immediate protection to the vulnerable components in the circuit.
• Reverse Stand-Off Voltage: The bidirectional nature of this TVS diode allows it to protect circuits from transients occurring in both directions along the signal or power lines.

Applications:

• Protection of I/O interfaces
• Voltage regulation for sensitive electronics
• Microcontroller or microprocessor voltage clamping
• Industrial control systems
• Consumer electronics surge protection
• Automotive electronics transient suppression
