Thermal and mechanical fit for the board
The SMBJ22A-13: Surface-mount assembly on the DO-214AA footprint uses standard reflow profiles; the SMB body dissipates pulse heat through the copper pad area, so the PCB land pattern should match the recommended pad geometry in the datasheet to keep the thermal impedance low. Power line protection is marked as 'No', meaning this device is intended for signal or low-voltage DC rail clamping rather than AC mains or high-energy power entry — the 600W rating suits it for 24V sensor supplies, PLC I/O rails, or telecom line cards where the transient energy is bounded.
Active production with straightforward sourcing
The base product number SMBJ22 covers the whole family — the '-13' suffix denotes the tape-and-reel packaging option, so verify the reel quantity matches your volume when ordering.
