70V standoff, 113V clamp — the protection envelope
The SMBJ70A-13: Rated for a 70V reverse standoff voltage (the rail it protects without conducting) and a 113V clamping maximum at 5.3A peak pulse current (10/1000µs waveform).
DO-214AA SMB — surface-mount footprint for dense boards
Housed in a DO-214AA (SMB) package, the SMBJ70A-13 is a surface-mount Zener TVS diode — the small footprint suits high-density PCB layouts in general-purpose protection applications.
The operating junction temperature range spans -55°C to 150°C, covering industrial enclosures and automotive under-hood environments without derating concerns.
