Frequently Asked Questions

What peak power and clamping voltage does the SMBJ85A-13-F provide during a surge event?

The SMBJ85A-13-F delivers 600 W peak pulse power dissipation (10/1000 µs waveform) and clamps transient voltages at a maximum of 137 V. This combination protects downstream components rated below 137 V from damage caused by lightning surges, ESD, or inductive switching transients on 85 V DC lines.

In which circuit topologies is the SMBJ85A-13-F most effective as a protection device?

The SMBJ85A-13-F is most effective in unidirectional protection roles on DC power rails, industrial sensor interfaces, and automotive electronics operating at up to 85 V. Its fast response time and 600 W surge rating handle inductive load switching transients, and its SMB package suits compact PCB layouts requiring TVS diodes on 85 V bus lines.

How does the SMBJ85A-13-F differ from the bidirectional SMBJ85CA in AC line protection scenarios?

Unlike the bidirectional SMBJ85CA, the SMBJ85A-13-F is a unidirectional device designed for DC circuits where transients appear in only one polarity. In AC line applications, a bidirectional device is required; however, for 85 V DC rails with single-polarity surges up to 600 W peak, the SMBJ85A-13-F provides lower clamping voltage and tighter clamp threshold than its bidirectional counterpart.
