Substitute Part Grouping Explanation

Substitution of the SA6.5A B0G is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part SA6.5A A0G maintains identical specifications in the following key areas:

• Voltage rating parameters: 6.5V reverse standoff, 7.22V minimum breakdown, and 11.2V maximum clamping voltage
• Current handling: 46A peak pulse current (10/1000µs waveform)
• Power dissipation: 500W peak pulse power
• Thermal performance: -55°C to 175°C operating temperature range
• Physical form factor: DO-204AC (DO-15) axial through-hole package
• Compliance certifications: ROHS3 compliant, REACH unaffected status
• Moisture sensitivity: MSL 1 (unlimited shelf life)

The SA6.5A A0G differs only in product status (active versus discontinued) and inventory availability, with no variation in electrical performance or mechanical compatibility.
