STMicroelectronics SMAJ5.0A-TR Transient Voltage Suppressor

The SMAJ5.0A-TR from STMicroelectronics is a robust transient voltage suppressor (TVS) diode designed to protect sensitive electronic equipment from voltage spikes and transients induced by lightning and other sudden voltage events. This component is a part of the SMAJ series, which is known for its reliability and efficiency in safeguarding circuits by clamping excessive transient voltages to a safe level before they can damage sensitive ICs.

Key Features

• Stand-off Voltage: The SMAJ5.0A-TR has a stand-off voltage of 5.0V, making it suitable for protecting circuits with a nominal working voltage of 5V.
• Peak Pulse Power: It can handle peak pulse power dissipation of 400W for 10/1000μs surge, ensuring high power protection for your devices.
• Clamping Voltage: With a low clamping voltage, this TVS diode provides an immediate response to any overvoltage condition, limiting the voltage that can be passed through to the protected components.
• Low Leakage Current: The device offers a low leakage current, minimizing power loss when the system is in standby mode and enhancing overall energy efficiency.
• Fast Response Time: The fast response time of the SMAJ5.0A-TR ensures that transients are clamped almost instantaneously, protecting the circuit without delay.
• Package: It comes in a compact SMA (DO-214AC) package, which is ideal for automated assembly and saves board space.
• Certifications: The product meets the IEC 61000-4-2 standard for ESD protection, IEC 61000-4-4 for EFT, and IEC 61000-4-5 for surge immunity. It is also RoHS compliant and Halogen-free, adhering to environmental standards.
