Additional Details

The CJ3134K-HF has a typical breakdown voltage (VBR) range, a standoff voltage (VRWM), and a maximum clamping voltage (VC). The peak pulse power dissipation (PPP) rating indicates its ability to handle high-energy transients. It is typically packaged in a small surface-mount package, such as SOD-323 or similar. The operating junction temperature range is generally between -55°C and +150°C. It provides unidirectional protection, meaning it is designed to protect against positive voltage transients.
