SA8.0A B0G Equivalent & Substitute Parts

Part Overview

The SA8.0A B0G is a unidirectional Transient Voltage Suppressor (TVS) diode manufactured by Taiwan Semiconductor Corporation, designed for general-purpose voltage clamping applications. This component features an 8V reverse standoff voltage with a 13.6V maximum clamping voltage and 38A peak pulse current capability in a through-hole DO-204AC (DO-15) axial package. The SA8.0A B0G is currently discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives to maintain circuit design continuity and procurement availability.

Substitute Part Grouping Explanation

Substitution of the SA8.0A B0G is determined by strict equivalence across the following critical electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Voltage - Reverse Standoff (Typ): 8V
• Voltage - Breakdown (Min): 8.89V
• Voltage - Clamping (Max) @ Ipp: 13.6V
• Current - Peak Pulse (10/1000µs): 38A
• Power - Peak Pulse: 500W
• Type: Zener
• Unidirectional Channels: 1

Mechanical Equivalence Criteria:

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

Compliance Equivalence Criteria:

• RoHS Status: ROHS3 Compliant
• Operating Temperature Range: -55°C ~ 175°C (TJ)

Parts meeting all these parameters are classified as direct functional equivalents and may be substituted without circuit redesign.

Frequently Asked Questions (FAQ)

Q: Can the SA8.0A A0G be used as a direct replacement for the SA8.0A B0G in existing circuit designs?

A: Yes. The SA8.0A A0G is electrically and mechanically identical to the SA8.0A B0G across all specified parameters, including voltage ratings, current handling, package type, and operating temperature range. No circuit modifications are required.

Q: What is the difference between the SA8.0A B0G and SA8.0A A0G part numbers?

A: The difference between B0G and A0G designations reflects internal manufacturing or date code variations within Taiwan Semiconductor Corporation's product line. Both variants meet identical electrical and mechanical specifications for the SA8.0 series 8V TVS diode.

Q: Are both parts suitable for the same applications?

A: Yes. Both the SA8.0A B0G and SA8.0A A0G are specified for general-purpose transient voltage suppression applications requiring 8V standoff voltage, 13.6V clamping voltage, and 38A peak pulse current capability in through-hole axial packages.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution eligibility is determined by matching: reverse standoff voltage (8V), breakdown voltage (8.89V minimum), clamping voltage (13.6V maximum), peak pulse current (38A), package type (DO-204AC/DO-15 axial), mounting method (through-hole), and compliance certifications (ROHS3, MSL 1).

Q: Is the DO-204AC package compatible with DO-15 footprints?

A: The DO-204AC and DO-15 designations refer to the same axial through-hole package format. Both terms are used interchangeably for this component category.

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

A: Both the SA8.0A B0G and SA8.0A A0G operate across a junction temperature range of -55°C to 175°C (TJ), suitable for industrial and commercial applications.
