600W Zener TVS — 154V standoff, 246V clamp
Clamping margin and temperature range
The 246V clamp ceiling means the protected bus must tolerate that voltage without damage — a common selection check for 150V–180V DC rails. Capacitance is 130pF at 1MHz — low enough for most signal lines but worth verifying against high-speed bus loading. The part is unidirectional (single channel) and offers no power line protection (not designed for AC mains).
Procurement should plan for alternate-sourced inventory or a pin-compatible replacement from the P6SMB series (e.g., P6SMB180A) or another TVS family with matching 154V standoff and 600W rating. Stock is sourced per RFQ through independent distribution and broker channels.
