SMBJ40A

The SMBJ40A is a transient voltage suppressor (TVS) diode produced by Shikues, a manufacturer of electronic components. This diode is designed to protect sensitive electronic circuits from damage caused by voltage spikes, surges, and electrostatic discharges (ESD).

Key Features:

• Transient Voltage Suppression: The SMBJ40A diode is specifically designed to suppress transient voltage spikes and surges that can damage sensitive electronic components. It clamps the voltage across the circuit to a safe level, protecting downstream components from overvoltage events.

• Reverse Standoff Voltage: The "40A" in the part number indicates a reverse standoff voltage of 40 volts. This is the voltage level below which the diode exhibits high impedance, effectively isolating the protected circuit from transient events.

• Peak Pulse Power Dissipation: The diode is capable of dissipating transient power spikes generated by voltage surges. It can handle short-duration pulses of high power without sustaining damage, ensuring reliable protection for the circuit.

• Low Clamping Voltage: The SMBJ40A diode features a low clamping voltage, which is the maximum voltage drop across the diode during a transient event. A low clamping voltage ensures that the protected circuit is subjected to minimal voltage stress, enhancing its robustness and reliability.

• Fast Response Time: Shikues designs its TVS diodes for fast response times to rapidly clamp transient voltages and limit their duration. Fast response times help prevent damage to sensitive electronic components by quickly diverting excess energy away from the circuit.

• Surface-Mount Package: The SMBJ40A diode is packaged in a surface-mount SMB (DO-214AA) package, which is compact and suitable for automated assembly processes. The surface-mount package enables easy integration onto printed circuit boards (PCBs) without the need for through-hole mounting.

• Wide Operating Temperature Range: The diode is designed to operate reliably over a wide temperature range, making it suitable for use in various environmental conditions and applications.

• Compliance with Industry Standards: Shikues' TVS diodes typically comply with industry standards and certifications for quality, reliability, and performance, ensuring compatibility with existing electronic systems and regulatory requirements.

Applications:

• Power Supply Protection: Used in power supplies, voltage regulators, and DC-DC converters to protect sensitive semiconductor devices from voltage transients and spikes.

• Communication Systems: Integrated into communication equipment, such as Ethernet switches, routers, and telecommunications systems, to safeguard against transient-induced damage.

• Industrial Control Systems: Deployed in industrial automation and control systems to protect microcontrollers, sensors, and other electronic components from voltage surges and ESD events.

• Automotive Electronics: Utilized in automotive electronics, including engine control units (ECUs), infotainment systems, and vehicle sensors, to ensure reliable operation in the presence of electrical disturbances.

• Consumer Electronics: Incorporated into consumer electronics products such as smartphones, tablets, and laptops to provide ESD protection for sensitive integrated circuits and connectors.

• LED Lighting: Used in LED lighting fixtures and driver circuits to protect LEDs and associated components from voltage spikes and transient events.
