SMBJ78A Frequently Asked Questions (FAQ)
-
The SMBJ78A can operate safely between -55°C to 150°C, but the maximum junction temperature should not exceed 150°C.
-
Choose a TVS diode with a standoff voltage (VWM) that is higher than the maximum operating voltage of your circuit, and a peak pulse current (IPP) that is higher than the expected surge current.
-
The SMBJ78A and SMBJ78CA are both TVS diodes with the same electrical characteristics, but the SMBJ78CA is an automotive-grade version with more stringent testing and qualification requirements.
-
The SMBJ78A is a unidirectional TVS diode, meaning it can only protect against positive surges. For bidirectional protection, you would need to use two SMBJ78A devices in series, with one device oriented in each direction.
-
Follow the recommended soldering profile and ensure the PCB is designed with a suitable land pattern and thermal relief to prevent overheating during soldering.
