SA7.0A B0G Equivalent & Substitute Parts

Part Overview

The SA7.0A B0G is a unidirectional Transient Voltage Suppressor (TVS) diode manufactured by Taiwan Semiconductor Corporation. This component is designed for general-purpose transient voltage protection applications, featuring a 7V reverse standoff voltage and 12V maximum clamping voltage with 43A peak pulse current capability. The SA7.0A B0G is packaged in a through-hole DO-204AC (DO-15) axial configuration and operates across a temperature range of -55°C to 175°C.

The SA7.0A B0G has been discontinued at DiGi Electronics. Identifying equivalent substitute parts ensures continued availability for circuit design, repair, and production applications where this specific TVS diode specification is required.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SA7.0A B0G are identified based on electrical and mechanical parameter equivalence. The critical parameters that determine substitution compatibility are:

Electrical Parameters:

• Voltage - Reverse Standoff (Typ): 7V
• Voltage - Breakdown (Min): 7.78V
• Voltage - Clamping (Max) @ Ipp: 12V
• Current - Peak Pulse (10/1000µs): 43A
• Power - Peak Pulse: 500W
• Type: Zener
• Unidirectional Channels: 1

Mechanical Parameters:

• Mounting Type: Through Hole
• Package / Case: DO-204AC, DO-15, Axial

Compliance Parameters:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• REACH Status: REACH Unaffected

Parts meeting all these criteria are electrically and mechanically interchangeable with the SA7.0A B0G in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

The SA7.0A A0G is a direct electrical and mechanical equivalent to the SA7.0A B0G. Both parts share identical electrical specifications across all critical parameters: 7V reverse standoff voltage, 7.78V minimum breakdown voltage, 12V maximum clamping voltage, and 43A peak pulse current. Both components are packaged in the DO-204AC (DO-15) through-hole axial configuration and operate across the same temperature range of -55°C to 175°C.

The SA7.0A A0G maintains full compliance with ROHS3, REACH, and MSL requirements, ensuring regulatory and environmental compatibility with the original SA7.0A B0G specification. The primary distinction is product status: the SA7.0A B0G is discontinued at DiGi Electronics, while the SA7.0A A0G is currently active and available in inventory (763 pieces in stock).

For applications requiring the SA7.0A B0G specification, the SA7.0A A0G provides full functional and physical interchangeability without design modification or circuit re-evaluation.

Frequently Asked Questions (FAQ)

Q: Can the SA7.0A A0G be used as a direct replacement for the SA7.0A B0G?

A: Yes. The SA7.0A A0G is electrically and mechanically equivalent to the SA7.0A B0G. Both parts have identical voltage ratings (7V reverse standoff, 12V clamping), current ratings (43A peak pulse), power dissipation (500W), and package configuration (DO-204AC through-hole axial). No circuit modifications are required.

Q: What are the key electrical parameters that define substitution compatibility?

A: Substitution compatibility for TVS diodes in this category is determined by: reverse standoff voltage (7V), breakdown voltage (7.78V minimum), clamping voltage (12V maximum at Ipp), peak pulse current (43A), and peak pulse power (500W). All substitute parts must match these specifications exactly.

Q: Are there any compliance or regulatory differences between the SA7.0A B0G and SA7.0A A0G?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry MSL rating 1 (unlimited moisture sensitivity). Regulatory and environmental compliance is identical.

Q: Does the package configuration differ between these parts?

A: No. Both the SA7.0A B0G and SA7.0A A0G use the DO-204AC (DO-15) through-hole axial package. Physical dimensions, lead spacing, and mounting requirements are identical.

Q: What is the operating temperature range for both parts?

A: Both the SA7.0A B0G and SA7.0A A0G operate across a junction temperature range of -55°C to 175°C (TJ). Thermal performance and temperature derating are equivalent.

Q: Why is the SA7.0A B0G discontinued while the SA7.0A A0G remains active?

A: Product status reflects supplier and distributor inventory decisions. The SA7.0A A0G is the active equivalent part currently available from Taiwan Semiconductor Corporation. Both parts share identical specifications and are functionally interchangeable.
