5 kW peak pulse, 100 V standoff — what the ratings mean
The 5.0SMDJ100CA/TR13 is a bidirectional TVS (transient voltage suppressor) diode in the YAGEO 5.0SMDJ series, specified 100 V reverse standoff — the working voltage the protected rail sees in normal operation. That 162 V ceiling is what the downstream circuit survives — the clamping voltage, not the standoff, is the let-through value the board designer budgets into the component stress margins. Choosing a 5 kW part over a 3 kW sibling means the clamping voltage stays lower under the same surge current, because the larger die has lower dynamic resistance at the clamp point.
No official YAGEO successor or cross-reference is listed for this exact order code.
