Littelfuse SMBJ30CA 1-Element Bi-Directional TVS Diode delivers 600 W of peak pulse power dissipation in a compact 2-pin DO-214AA (SMB) surface mount package. Designed for transient voltage suppression, this diode protects sensitive electronic equipment and circuits against voltage spikes and surges by clamping voltage effectively.
With a single element and bi-directional configuration, SMBJ30CA offers symmetrical clamping capability suitable for AC or DC circuits. The device has a minimum breakdown voltage of 33.3 V and operates reliably across a wide temperature range from -65°C to 150°C, making it ideal for demanding industrial, automotive, and electronic applications.
The diode supports a maximum reverse stand-off voltage of 30 V and can handle surge currents up to 12.4 A during transient events. Its ultra-low leakage current of 1μA guarantees minimal power loss in steady-state conditions, while the clamping voltage of 48.4 V ensures effective circuit protection.
Its compact physical dimensions of 4.57 mm length, 3.94 mm width, and 2.237 mm height facilitate high-density PCB layouts with surface mount technology. The device complies with standard industrial specifications but has no specific certifications listed.
Single-element diode configuration optimizes protection performance. Bidirectional design enables use in AC and DC applications. 600 W peak pulse power rating for robust transient suppression. Surface mount DO-214AA package supports compact electronic designs.
Operating temperature range from -65°C to 150°C for high reliability. Low leakage current minimizes power wastage in circuits. Clamping voltage of 48.4 V limits voltage spikes effectively. 2-pin configuration simplifies integration into various PCBs.
Suitable for use in industrial, automotive, and power electronics.
This Littelfuse product is specifically designed to enhance circuit durability and reliability by protecting electronic components from voltage transients, making it a dependable choice for engineers and manufacturers in electronics and electrical equipment sectors.
