Substitute Part Grouping Explanation

Substitution of TVS diodes is determined by strict equivalence across electrical performance parameters and mechanical compatibility. The SA64A B0G substitute must maintain identical specifications in the following critical areas:

Electrical Parameters (Must Match Exactly):

• Reverse standoff voltage: 64V
• Breakdown voltage minimum: 71.1V
• Maximum clamping voltage at peak pulse current: 103V
• Peak pulse current rating: 5A
• Peak pulse power dissipation: 500W
• Unidirectional channel configuration: 1 channel

Mechanical Parameters (Must Match Exactly):

• Package type: DO-204AC (DO-15) axial through-hole
• Mounting configuration: Through-hole

Compliance Parameters (Must Match Exactly):

• RoHS3 compliance
• REACH unaffected status
• Operating temperature range: -55°C to 175°C

Substitute parts meeting all these criteria are functionally and mechanically interchangeable with the SA64A B0G in circuit protection applications.
