SLKOR SMBJ – Reliable Line of TVS Diodes Now Available

SLKOR SMBJ Series is an advanced line of TVS (Transient Voltage Suppression) diodes, designed to provide effective protection for electronic circuits against surges and harmful voltage transients. They safeguard devices from both electrostatic discharge (ESD) and sudden voltage spikes caused by atmospheric phenomena such as surges. Thanks to their ultra-fast response time, SMBJ diodes instantly clamp excess energy, preventing damage to sensitive electronic components. Their robust design ensures reliable performance in demanding industrial and consumer environments, guaranteeing the stability and safety of entire systems.

Additionally, the SMBJ series includes both unidirectional and bidirectional models, allowing adaptation to a wide range of applications and circuits by providing protection against surges with different polarity. High impulse power and resistance to repeated pulses make these diodes an ideal choice for protecting power circuits, communication interfaces, IoT devices, and industrial automation systems.

SMBJ series characteristics:

• Breakdown voltage: from 20 V to 51 V (depending on the model)
• Maximum impulse power: 600 W
• Response time: under 1 ns
• Package type: SMB (DO-214AA) – surface mount (SMD)
• Voltage-current characteristic types: unidirectional (e.g., SMBJ20A) and bidirectional (e.g., SMBJ28CA)
• Long service life and high reliability

Applications:

• Power systems (SMPS, AC/DC, DC/DC) – protection of converters and power supplies against surges.
• Industrial equipment & automation – reliable protection of controllers, inverters, and sensors.
• Telecommunication & networking equipment – safeguarding ports and network devices from disturbances.
• Automotive electronics (ECU, CAN, LIN, sensors) – protection of modules and bus systems in vehicle installations.
• Control & security systems – stable operation of control panels, central units, and access control.
• ESD-sensitive PCBs – protection of integrated circuits against electrostatic discharge.
• Data ports & signal connectors (USB, RS-232, Ethernet) – reliable protection of communication interfaces without signal degradation.
