SMBJ170A TVS diode for 170 V circuits

The YINGHUA SMBJ170A is a transient voltage suppressor designed to protect sensitive electronics from electrostatic discharge and voltage spikes. It uses a DO-214AA package suitable for surface-mount assembly on printed circuit boards. Engineers specifying over-voltage protection for 170 volt working voltages will find this device matches the requirement. The component is supplied new and ready for production use.

Low capacitance limits signal loading

The diode clamps fast transients while presenting low capacitance to the protected line, preserving signal integrity in normal operation. Leakage current remains minimal at the rated stand-off voltage, so static power draw is negligible. The DO-214AA body dissipates pulse energy efficiently without active cooling. No audible noise is generated during clamping events.

Questions about this item

How is the SMBJ170A TVS diode with DO-214AA-2 package installed on a PCB?

Place the DO-214AA-2 package on the pads with correct polarity, apply solder paste, and reflow. The step often missed is verifying the cathode band orientation before soldering.

What maintenance or replacement will the SMBJ170A TVS diode need after absorbing transients?

Inspect the 170 V standoff device after any surge event; if the junction is shorted or leakage has risen, replace the diode as it cannot self-heal.
