SA110A B0G Equivalent & Substitute Parts

Part Overview

The SA110A B0G is a unidirectional Transient Voltage Suppressor (TVS) diode manufactured by Taiwan Semiconductor Corporation, designed for general-purpose overvoltage protection applications. This component features a 110V reverse standoff voltage with a 177V maximum clamping voltage and 2.9A peak pulse current capability in a through-hole DO-204AC (DO-15) axial package.

The SA110A B0G is currently discontinued at DiGi Electronics. Identifying equivalent substitute parts ensures design continuity and maintains supply chain reliability for applications requiring this specific voltage suppression performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of TVS diodes is determined by electrical and mechanical parameter equivalence. For the SA110A B0G, substitute parts must satisfy the following criteria:

Electrical Parameters (Critical for Substitution):

• Voltage - Reverse Standoff (Typ): 110V
• Voltage - Breakdown (Min): 122V
• Voltage - Clamping (Max) @ Ipp: 177V
• Current - Peak Pulse (10/1000µs): 2.9A
• Power - Peak Pulse: 500W
• Unidirectional configuration (1 channel)
• Zener type classification

Mechanical Parameters (Critical for Substitution):

• Mounting Type: Through Hole
• Package / Case: DO-204AC (DO-15) Axial
• Operating Temperature Range: -55°C to 175°C (TJ)

Compliance Parameters:

• RoHS3 Compliant
• REACH Unaffected
• Moisture Sensitivity Level: 1 (Unlimited)

Parts meeting all electrical, mechanical, and compliance parameters are classified as direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

The SA110A A0G is a direct electrical and mechanical equivalent to the SA110A B0G. Both components share identical electrical specifications across all critical parameters: 110V reverse standoff voltage, 122V minimum breakdown voltage, 177V maximum clamping voltage, and 2.9A peak pulse current.

The SA110A A0G differs from the main part only in product status: it is currently Active, whereas the SA110A B0G is Discontinued at DiGi Electronics. Both parts are manufactured by Taiwan Semiconductor Corporation and comply with ROHS3 and REACH requirements.

For applications currently using the SA110A B0G, the SA110A A0G provides full functional and physical compatibility. The active product status of the SA110A A0G ensures ongoing availability and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the SA110A A0G be used as a direct replacement for the SA110A B0G?

A: Yes. The SA110A A0G is electrically and mechanically identical to the SA110A B0G. All electrical parameters, including voltage ratings, current ratings, and power dissipation, are equivalent. Both components use the same DO-204AC (DO-15) axial through-hole package and operate across the same temperature range.

Q: What is the difference between the SA110A B0G and SA110A A0G?

A: The only difference is product status. The SA110A B0G is discontinued at DiGi Electronics, while the SA110A A0G is currently active. The suffix designations (B0G versus A0G) indicate different manufacturing batches or revisions, but the electrical and mechanical specifications are identical.

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

A: No. Both the SA110A B0G and SA110A A0G are ROHS3 compliant, REACH unaffected, and carry Moisture Sensitivity Level 1 (Unlimited). Compliance certifications are identical.

Q: Can these TVS diodes be used in PCB designs with surface-mount components?

A: No. Both the SA110A B0G and SA110A A0G are through-hole components in DO-204AC (DO-15) axial packages. They are designed for through-hole mounting only and are not suitable for surface-mount applications.

Q: What applications are these TVS diodes suitable for?

A: Both components are classified for general-purpose transient voltage suppression applications. The 110V reverse standoff voltage and 177V clamping voltage make them suitable for protecting circuits operating in the 110V nominal voltage range from transient overvoltage events.

Q: Is inventory availability a consideration when selecting between these parts?

A: Yes. The SA110A A0G has 964 pieces in stock, while the SA110A B0G has 751 pieces in stock. For new designs or long-term supply requirements, the SA110A A0G is preferred due to its active product status and higher inventory levels.
