The SMBJ28A-TR is a unidirectional Zener TVS diode designed for general purpose transient voltage suppression. It features a reverse standoff voltage of 28V and a maximum clamping voltage of 45.4V at a peak pulse current of 13.8A. The device can handle 600W of peak pulse power (10/1000μs waveform), making it suitable for protecting sensitive electronics from voltage transients.
This TVS diode is housed in a DO-214AA (SMB) surface mount package, which is ideal for automated assembly and space-constrained designs. It operates over a junction temperature range of -55°C to 150°C, ensuring reliable performance in harsh environments. The part is RoHS3 compliant and has an MSL of 1 (unlimited), simplifying handling and storage.
Typical applications include general purpose circuit protection in consumer, industrial, and communication equipment. The SMBJ28A-TR is a direct replacement for industry-standard SMBJ28A devices and is available in tape and reel packaging for high-volume production.
