The SMC30J30A is a unidirectional Zener TVS diode from STMicroelectronics designed for general-purpose transient voltage suppression. It features a reverse standoff voltage of 30V, a maximum clamping voltage of 48.4V at the peak pulse current, and a peak pulse power dissipation of 3000W (3kW) under 10/1000µs waveform. The device provides single-channel protection and is not intended for power line protection applications.
With a peak pulse current rating of 62A (10/1000µs), the SMC30J30A is suitable for protecting sensitive electronics from voltage transients induced by lightning, inductive load switching, or electrostatic discharge. The device operates over a junction temperature range of -55°C to 175°C, making it robust for demanding environments.
The SMC30J30A is supplied in a DO-214AB (SMC) surface-mount package, which is compatible with standard reflow soldering processes. The package is compliant with RoHS3 and REACH requirements (unverified), and has an MSL rating of 1 (unlimited). The component is designed for ease of integration into automated assembly lines.
Typical applications include general-purpose circuit protection in consumer electronics, industrial equipment, and communication systems. The part is cross-referenced with DigiKey part numbers 497-12218-2-ND, 497-12218-1-ND, and 497-12218-6-ND.
