SA7.5A B0G Equivalent & Substitute Parts

Part Overview

The SA7.5A 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 7.5V reverse standoff voltage and 12.9V maximum clamping voltage at peak pulse current. The device is packaged in a DO-204AC (DO-15) axial through-hole configuration and is rated for 40A peak pulse current with 500W peak pulse power dissipation.

The SA7.5A B0G has been discontinued at DiGi Electronics. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for production, repair, and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SA7.5A B0G are identified based on electrical and mechanical parameter equivalence. The critical parameters that determine substitution compatibility are:

• Voltage - Reverse Standoff (Typ): 7.5V
• Voltage - Clamping (Max) @ Ipp: 12.9V
• Current - Peak Pulse (10/1000µs): 40A
• Power - Peak Pulse: 500W
• Package / Case: DO-204AC (DO-15), Axial
• Type: Zener, Unidirectional (1 channel)
• Operating Temperature Range: -55°C to 175°C (TJ)

Parts meeting all these electrical and mechanical specifications are classified as direct equivalents and can be substituted without circuit redesign or board layout modification.

Parameter Comparison

Engineering Selection Recommendations

The SA7.5A A0G is a direct electrical and mechanical equivalent to the SA7.5A B0G. Both parts are manufactured by Taiwan Semiconductor Corporation within the SA series and share identical electrical specifications across all critical parameters: 7.5V reverse standoff voltage, 12.9V clamping voltage, 40A peak pulse current, and 500W peak pulse power rating.

The SA7.5A A0G is currently in active product status, whereas the SA7.5A B0G is discontinued. Both parts comply with ROHS3 and REACH requirements, ensuring regulatory compliance for new designs and replacements. The SA7.5A A0G maintains the same DO-204AC (DO-15) axial through-hole package, permitting direct board-level substitution without layout modification.

The SA7.5A A0G is suitable for direct replacement in all applications where the SA7.5A B0G was originally specified.

Frequently Asked Questions (FAQ)

Q: Can the SA7.5A A0G be used as a direct replacement for the SA7.5A B0G?

A: Yes. The SA7.5A A0G is electrically and mechanically equivalent to the SA7.5A B0G. All electrical parameters, including reverse standoff voltage, clamping voltage, peak pulse current, and power dissipation, are identical. The package configuration (DO-204AC, DO-15, axial) is the same, enabling direct board-level substitution.

Q: What is the difference between the SA7.5A B0G and SA7.5A A0G?

A: The primary difference is product status. The SA7.5A B0G is discontinued at DiGi Electronics, while the SA7.5A A0G is active. The electrical and mechanical specifications are identical. The designations B0G and A0G represent different manufacturing or distribution batches from Taiwan Semiconductor Corporation.

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

A: No. Both the SA7.5A B0G and SA7.5A A0G are ROHS3 compliant and REACH unaffected. Moisture sensitivity level (MSL) is 1 (Unlimited) for both parts. Regulatory compliance is equivalent.

Q: Can these parts be used interchangeably in existing designs?

A: Yes. The SA7.5A A0G can be substituted for the SA7.5A B0G without circuit redesign or board layout modification. The identical electrical ratings and axial through-hole package ensure functional and physical compatibility.

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

A: Both the SA7.5A B0G and SA7.5A A0G operate across a junction temperature range of -55°C to 175°C (TJ), providing equivalent thermal performance across industrial and extended temperature applications.

Q: Are inventory levels a consideration for selection?

A: The SA7.5A A0G has 872 pieces in stock, while the SA7.5A B0G has 743 pieces available. Given the discontinued status of the SA7.5A B0G, the SA7.5A A0G is the recommended selection for ongoing component procurement.
