Overview

The SMBJ5.0CA is a bidirectional transient voltage suppressor (TVS) diode designed to protect sensitive electronic components from voltage transients induced by lightning and other transient voltage events. It features a 600W peak pulse power rating in a compact surface-mount SMB package, making it a staple for board-level protection. With a low standoff voltage of 5V and a fast response time of less than 5.0 picoseconds, it is ideal for 5V logic rail protection.

Why Choose This Part

The SMBJ5.0CA offers a high 600W surge capacity in a small DO-214AA footprint, providing a superior power-to-size ratio. Its bidirectional design allows for protection against transients of both polarities without requiring a second component. Additionally, it features a fast response time and low clamping voltage to ensure downstream ICs are not exposed to destructive potential.

Applications

5V Power Rail Protection
Clamping overvoltage transients on 5V DC power lines in consumer and industrial electronics.
Communication Interfaces
Protecting RS-232, RS-485, and other low-speed data lines from ESD and EFT transients.
Computing Peripherals
Safeguarding USB ports and internal circuitry in laptops and desktop computers.
Portable Electronics
Space-efficient surge protection for battery-powered devices and handheld communication equipment.
