SMBJ16CA-13-F

SMBJ16CA-13-F is a surface‑mount transient voltage suppressor (TVS) diode from the SMBJ family. It protects circuits from voltage transients and surges on DC rails or data lines. The “16” indicates a nominal stand‑off voltage around 16 V, and the “CA” suffix denotes the bidirectional variant. The “-13‑F” typically references packaging/reel code and RoHS compliance (lead‑free). It is sold in an SMB package and offers high peak pulse power (about 600 W for the standard 10/1000 µs waveform, depending on vendor). Clamping voltage rises with current and is defined by the device’s characteristics.
Common uses include protecting 12 V automotive lines, USB/data interfaces, and general surge protection on power rails. For design, place the diode across the protected rails with correct polarity for the bidirectional variant, ensure VRWM is above normal operating voltage, and verify that the surge/current ratings exceed expected transients. Available from Littelfuse and other vendors.

SMBJ16CA-13-F is a TVS diode used to clamp transient voltages on low‑voltage circuits. Primary applications include:
- Automotive and transportation electronics (protects 12–24V power rails and ECUs from surges/load-dumps)
- DC power supplies, LED drivers, battery chargers, and other 12– to 24‑V rail protection
- Signal and data lines (CAN/LIN, USB, Ethernet, HDMI, etc.) to guard against ESD and transient spikes
- Telecom and industrial equipment protection at power entry or I/O ports
- Anywhere sensitive electronics require surge/ESD protection on power or signal lines

It uses the SMB package (DO-214AA), i.e., a surface-mount TVS diode package.
