What this Zener TVS diode protects and where it fits
The 6.5V minimum breakdown voltage means it starts conducting just above the 6V rail, clamping transients before they reach downstream silicon. The -55°C to 175°C junction temperature range suits it for under-hood automotive, industrial control panels, and outdoor telecom power feeds where ambient heat and cold cycles are routine.
Voltage window and surge rating in context
The 6V standoff allows the diode to sit across a 5V or 6V rail without leaking appreciably. The 11V clamp gives a 5V headroom above the rail — tight enough to protect 5V logic or a 6V sensor supply without stressing the downstream regulator. The 500W peak pulse rating is the energy the part can absorb in a single surge event; the 258A peak current (8/20µs) confirms it handles short, high-current spikes typical of inductive load dumps or lightning-coupled transients.
Production status and sourcing posture
The B Axial through-hole package is a standard form factor, widely inventoried across distribution. Sourced per RFQ against your BOM quantity; no stock-holding claim, but the active status means lead times are predictable and the part is not subject to last-time-buy windows.
