The SMBJ54A can operate from -55°C to 150°C, but the maximum junction temperature (Tj) should not exceed 150°C.
Choose the correct SMBJ54A variant based on the required standoff voltage, peak pulse current, and package type. Consult the datasheet and onsemi's selection guide for more information.
Use a PCB layout that minimizes lead inductance and provides a low-impedance path to ground. Keep the device as close to the protected circuit as possible, and use a ground plane to reduce noise and EMI.
Yes, the SMBJ54A is suitable for high-reliability and aerospace applications. However, ensure that you follow the relevant industry standards and guidelines, such as MIL-PRF-19500 or NASA's EEE-INST-002.
Follow proper ESD handling procedures when handling the SMBJ54A, such as using an ESD wrist strap or mat, and storing the devices in anti-static packaging.
