SMAJ30CA Description

Short technical summary and product information.

The SMAJ30CA is a bidirectional transient voltage suppression (TVS) diode from Würth Elektronik. It is designed to protect sensitive electronics from voltage transients induced by lightning, inductive load switching, and electrostatic discharge. Key electrical specifications include a reverse standoff voltage of 30 V, a breakdown voltage of 35.05 V ±5% at 1 mA, and a maximum clamping voltage of 48.4 V at the peak pulse current of 8.3 A (10/1000 µs waveform). The device can handle a peak pulse power dissipation of 400 W (10/1000 µs) and a steady state power dissipation of 3.3 W at 50°C. The leakage current is limited to 1 µA at the reverse standoff voltage. The diode is housed in a surface-mount DO-214AC (SMA) package, suitable for automated assembly. It operates over a wide temperature range of -65°C to 150°C. The component is RoHS, REACH, and Halogen Free compliant, and carries UL approvals (UL497B, UL1449). It is ideal for use in power supply lines, data lines, and general-purpose circuit protection applications where bidirectional protection is required.
