Littelfuse 1-Element Uni-Directional TVS Diode 600W Surface Mount DO-214 Package SMBJ5.0A

Littelfuse SMBJ5.0A is a high-performance single-element Uni-Directional Transient Voltage Suppressor (TVS) diode designed for protecting electronic circuits from voltage spikes. Housed in a compact DO-214 surface mount package, it efficiently clamps voltage to safe levels during transient events, with a peak pulse power dissipation of 600 watts.

This diode features a breakdown voltage threshold starting at 6.4 volts and has a maximum reverse stand-off voltage of 5 volts, making it ideal for protecting sensitive semiconductor components. The clamping voltage of 9.2 volts ensures that voltage surges are limited effectively to prevent damage.

Engineered for durability and reliability, the SMBJ5.0A operates within a broad temperature range from -65°C to 150°C, suitable for industrial, commercial, and automotive adjacent applications. Its maximum peak pulse current of 65.3 amperes allows it to absorb substantial transient energy, while the low maximum reverse leakage current of 800 microamperes reduces power loss in steady-state conditions.

The diode’s 2-pin configuration and surface mount technology enable easy integration into PCBs for automated assembly and efficient space utilization. While it does not carry automotive certification, it meets common industrial electronic standards providing dependable transient voltage suppression.

Typical use cases include protection in power supplies, telecommunications equipment, industrial controllers, and general electronic devices requiring robust protection against electrical transients and electrostatic discharge (ESD).
