Device identity and protection envelope
The SMBJ75A-13-F: It comes in a DO-214AA (SMB) package and is rated for a peak pulse power of 600W (10/1000µs waveform). The operating junction temperature range spans -55°C to 150°C, covering industrial and some automotive under-hood environments.
No power line protection is claimed (the part is intended for signal or low-voltage DC rail clamping). The single unidirectional channel means it protects one line per device; for bidirectional or multi-line applications, pair two devices or select a different series.
The base product number is SMBJ75, and the -13-F suffix denotes the Tape & Reel packaging variant.
