The SMAJ12A-13 from Diodes Incorporated is a robust surface-mount Transient Voltage Suppressor (TVS) diode designed to protect sensitive electronic equipment from voltage transients induced by system inductive load switching and lightning. This TVS diode is ideal for the absorption of transient overvoltage that can damage delicate circuits in a variety of applications, including consumer electronics, automotive, industrial control systems, and telecommunications.

Key Features

• Stand-off Voltage: The device has a stand-off voltage of 12V, which is the maximum voltage that the diode can withstand without conducting significant current.
• Peak Pulse Power: It can handle a peak pulse power of 400W for a 10/1000μs waveform, ensuring protection against high energy transients.
• Clamping Voltage: The SMAJ12A-13 has a clamping voltage of 19.9V, which is the maximum voltage drop across the diode when subjected to a peak impulse current.
• Unidirectional: This component is unidirectional, providing protection for one-way electrical paths.
• Low Leakage Current: It exhibits low leakage current, minimizing power loss when the diode is in its standby state and improving overall efficiency.
• Fast Response Time: The diode's response time to transient events is less than 1 picosecond, offering immediate protection against voltage spikes.
