Littelfuse 1-Element Bi-Directional TVS Diode, 600 W, 2-Pin DO-214 SMBJ5.0CA

Littelfuse SMBJ5.0CA is a 1-element bi-directional Transient Voltage Suppressor (TVS) diode designed for robust surge protection in electronic circuits. With a peak pulse power dissipation capacity of 600 W and a compact 2-pin DO-214 surface mount package, this diode is engineered to shield sensitive components from transient voltage spikes.

Its bi-directional configuration allows it to clamp voltage surges in both polarity directions, making it ideal for AC and DC signal protection in communications, industrial controls, and power supply applications. The diode operates reliably across a wide temperature range (-65°C to 150°C), suitable for industrial and commercial environments where electrical transients are common.

The device features a minimum breakdown voltage of 6.4 V and a maximum reverse stand-off voltage of 5 V, ensuring precise threshold activation to protect load circuits without nuisance tripping. A maximum peak pulse current of 65.3 A coupled with a clamping voltage of 9.2 V helps absorb severe transients, while its low maximum reverse leakage current (800 μA) preserves energy efficiency during normal operation.

Physical dimensions are optimized for high-density PCB layouts, measuring 4.57 mm in length, 3.94 mm in width, and 2.237 mm in height. This compact form factor, combined with reliable ESD protection, makes the SMBJ5.0CA series suitable for industrial, telecommunications, computing, and automotive electronics where transient suppression and device ruggedness are critical.

Single element diode configuration ensures reliable transient voltage suppression. Bi-directional design suitable for protecting circuits against polarity voltage spikes. 600 W peak pulse power dissipation rating provides robust surge protection.

Wide operating temperature range from -65°C to 150°C for diverse application conditions. Compact DO-214 surface mount package for efficient PCB footprint and assembly. Precise clamping voltage of 9.2 V and reverse stand-off of 5 V protects sensitive circuitry timely.
