Frequently Asked Questions
What are the standoff voltage and clamping voltage specifications of the SMBJ28CAQ-13-F?
The SMBJ28CAQ-13-F has a 28 V standoff voltage and a maximum clamping voltage of 45.4 V at peak pulse current. The nominal breakdown voltage is 33.45 V with a minimum of 31.1 V and maximum of 35.8 V, providing reliable bidirectional transient suppression for 24 V to 28 V bus systems in automotive and industrial environments.
Is the SMBJ28CAQ-13-F suitable for automotive 28 V bus protection in AEC-Q101 compliant designs?
Yes, the SMBJ28CAQ-13-F carries AEC-Q101 qualification, making it compliant for automotive applications on 28 V power buses used in trucks, buses, and heavy commercial vehicles. The -Q suffix confirms it meets Grade 1 automotive reliability standards, with operating temperatures typically from -55°C to +150°C and robust ESD protection across 1500 W peak pulse power.
How does a bidirectional TVS diode like the SMBJ28CAQ-13-F differ from a unidirectional version for AC line protection?
A bidirectional TVS such as the SMBJ28CAQ-13-F clamps voltage transients of either polarity, with its 28 V standoff voltage blocking both positive and negative surges up to 45.4 V clamping level. A unidirectional version only suppresses one polarity, so for AC signals or reversible DC buses, the bidirectional SMBJ28CAQ-13-F provides complete protection across both half-cycles, critical in motor driver and relay coil applications.
