The reverse standoff voltage is 20 V, meaning the diode does not conduct at normal operating voltages below this level.
The SMB footprint is widely used across the 1.5SMBJ series, so a single PCB land pattern can accommodate multiple voltage variants without layout changes.
The 1.5SMBJ20A is available to order through independent distribution. Pricing and lead time are confirmed at quote time against the requested quantity — send an RFQ for a firm commercial offer.
It is AEC-Q101 qualified for automotive applications.
