The SMAJ14A-13-F is a robust transient voltage suppressor (TVS) diode designed by Diodes Incorporated to protect sensitive electronic equipment from voltage spikes and transients. This TVS diode is specifically engineered to shield circuits against the detrimental effects of voltage transients induced by inductive load switching and lightning, particularly in exposed and high-reliability environments.

Key Features

• Stand-Off Voltage: The device offers a stand-off voltage of 14V, making it suitable for a variety of applications that require this level of protection.
• Peak Pulse Power: It can handle a peak pulse power of 400W for 10/1000μs waveforms, providing a robust shield against high energy transients.
• Clamping Voltage: During a transient voltage event, the SMAJ14A-13-F clamps to a maximum voltage of 23.2V, ensuring that the protected components remain safe from overvoltage conditions.
• Low Incremental Surge Resistance: The device offers low resistance during surge events, which helps in minimizing the voltage drop across the diode when subjected to high surge currents.
• Unidirectional Protection: This component provides unidirectional protection, making it ideal for DC voltage applications where the polarity is fixed.
• Package: Housed in a low-profile SMA package, the SMAJ14A-13-F is designed for automated placement and is compatible with high-volume electronics assembly.
• Compliance: It complies with the RoHS directive, making it environmentally friendly and suitable for use in green products.
