Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SA130A B0G are identified based on electrical and mechanical parameter equivalence. The critical parameters determining substitution eligibility are:

• Voltage Rating: Reverse standoff voltage of 130V (Typ), breakdown voltage minimum of 144V, and maximum clamping voltage of 209V @ Ipp
• Current Rating: Peak pulse current of 2.5A (10/1000µs pulse)
• Power Dissipation: Peak pulse power of 500W
• Package Configuration: Through-hole mounting in DO-204AC (DO-15) axial package
• Thermal Performance: Operating temperature range of -55°C to 175°C (TJ)
• Regulatory Compliance: ROHS3 compliance, REACH unaffected status, and MSL 1 rating

Parts meeting all these electrical and mechanical specifications are classified as direct substitutes. Variations in manufacturer part number suffix or product status (active versus discontinued) do not affect functional equivalence when all rated parameters remain identical.

Parameter Comparison

Engineering Selection Recommendations

The SA130A A0G is a direct functional equivalent to the SA130A B0G. Both components share identical electrical specifications, thermal ratings, and mechanical packaging. The primary distinction is product status: the SA130A B0G is discontinued at DiGi Electronics, while the SA130A A0G maintains active status.

For new designs or component replenishment, the SA130A A0G is the appropriate selection. Both parts carry ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment. The MSL 1 rating indicates unlimited shelf life under standard storage conditions.

The SA130A A0G is currently available with 916 pieces in stock, providing supply continuity for applications requiring 130V standoff voltage protection with 2.5A peak pulse current capability in through-hole axial configuration.

Frequently Asked Questions (FAQ)

Q: Can the SA130A A0G be used as a direct replacement for the SA130A B0G?

A: Yes. The SA130A A0G is electrically and mechanically identical to the SA130A B0G. All voltage ratings, current specifications, thermal performance, and package dimensions are equivalent. The difference in part number suffix reflects manufacturing lot or revision tracking only.

Q: What is the significance of the part number suffix (B0G versus A0G)?

A: The suffix indicates manufacturing batch or revision designation. Both suffixes represent the same base product (SA130) with identical electrical and mechanical specifications. The suffix does not affect functional performance or compatibility.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both the SA130A B0G and SA130A A0G carry identical ROHS3 compliance, REACH unaffected status, and MSL 1 moisture sensitivity ratings. No additional testing or qualification is required when substituting between these parts.

Q: What applications are these TVS diodes suitable for?

A: These components are rated for general-purpose transient voltage suppression. The 130V standoff voltage and 209V clamping voltage are appropriate for protecting circuits operating in this voltage range from transient overvoltage events.

Q: Can these parts be used in surface-mount applications?

A: No. Both the SA130A B0G and SA130A A0G are through-hole components in DO-204AC (DO-15) axial package configuration. They are designed for through-hole PCB mounting only.

Q: What is the operating temperature range for these components?

A: Both parts operate across -55°C to 175°C junction temperature (TJ). This range covers industrial and extended-temperature applications.

Q: Is the SA130A A0G available in higher inventory quantities?

A: The SA130A A0G currently has 916 pieces in stock, compared to 853 pieces for the discontinued SA130A B0G. Availability may vary by distributor and time of inquiry.
