Product Description
Littelfuse SMBJ18CA is a 1-Element Bi-Directional Transient Voltage Suppressor (TVS) diode designed for surface mount applications. It features a DO-214 package type with two pins, ideal for compact electronic circuits in industrial and commercial settings.
This device offers a peak pulse power dissipation of 600 watts and is rated for a maximum peak pulse current of 20.6 amperes, ensuring robust protection against voltage spikes and transient surges. The minimum breakdown voltage of 20 volts and a clamping voltage of 29.2 volts provide effective voltage regulation and suppression during surge events.
The SMBJ18CA operates reliably over a wide temperature range from -65°C to 150°C, making it suitable for demanding environments including industrial electronics, power supplies, telecommunication equipment, and consumer electronics.
Its small DO-214 surface-mount package dimensions (length 4.57 mm, width 3.94 mm, height 2.237 mm) enable space-saving PCB designs. The diode configuration is single and bi-directional, protecting circuits against overvoltage in both polarities. The maximum reverse leakage current is low at 1 microampere, minimizing power loss during normal operation.
Single diode configuration with bi-directional protection. High peak pulse power rating of 600W for transient overvoltage protection. Effective clamping voltage of 29.2V safeguards sensitive components. Wide operating temperature range from -65°C to 150°C for industrial use.
Compact DO-214 surface mount package with 2 pins. Low maximum reverse leakage current of 1 μA reduces standby power loss. Suitable for applications in power supplies, communication equipment, and industrial electronics.
This TVS diode is part of the Littelfuse SMBJ series known for reliable surge protection in discrete semiconductor applications. It is ideal for industrial and laboratory environments requiring robust electronic component protection.
