• REACH Status: REACH Unaffected

Parts meeting all these criteria are classified as direct electrical and mechanical equivalents.

Parameter Comparison

Engineering Selection Recommendations

The SA150A A0G is a direct equivalent substitute for the SA150A B0G. Both components are manufactured by Taiwan Semiconductor Corporation and share identical electrical specifications, mechanical packaging, and compliance certifications.

The primary distinction between these parts is product status: the SA150A B0G is discontinued at DiGi Electronics, while the SA150A A0G maintains active status with higher inventory availability (1184 pieces versus 931 pieces). Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.

For new designs or component replenishment, the SA150A A0G is the appropriate selection due to its active product status and sustained supply chain availability. Existing designs utilizing the SA150A B0G can transition to the SA150A A0G without circuit modification or performance impact.

Frequently Asked Questions (FAQ)

Q: Can the SA150A A0G be used as a direct replacement for the SA150A B0G in existing circuits?

A: Yes. The SA150A A0G is electrically and mechanically identical to the SA150A B0G. All voltage ratings, current specifications, temperature ranges, and package dimensions are equivalent. No circuit redesign is required.

Q: What is the difference between the SA150A B0G and SA150A A0G part numbers?

A: The difference lies in the suffix designation (B0G versus A0G), which typically indicates manufacturing date code or production batch variation. The electrical and mechanical specifications are identical. The SA150A A0G is currently in active production status.

Q: Are both parts RoHS compliant?

A: Yes. Both the SA150A B0G and SA150A A0G are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic components.

Q: What is the operating temperature range for these TVS diodes?

A: Both parts operate across a junction temperature range of -55°C to 175°C (TJ), suitable for industrial and commercial applications.

Q: Is the DO-204AC package the same as DO-15?

A: Yes. DO-204AC and DO-15 are equivalent designations for the same axial through-hole package format used in these TVS diodes.

Q: What is the peak pulse power rating?

A: Both parts are rated for 500W peak pulse power with a peak pulse current of 2.1A at a 10/1000µs waveform.

Q: Why is the SA150A B0G listed as discontinued?

A: The SA150A B0G is discontinued at DiGi Electronics, indicating it is no longer actively stocked or produced. The SA150A A0G remains in active production and is the recommended selection for ongoing supply requirements.
