SA9.0A B0G Equivalent & Substitute Parts

Part Overview

The SA9.0A B0G is a unidirectional Transient Voltage Suppressor (TVS) diode manufactured by Taiwan Semiconductor Corporation. This component is designed for general-purpose transient voltage suppression applications, featuring a 9V reverse standoff voltage and 15.4V maximum clamping voltage. The device is packaged in a DO-204AC (DO-15) through-hole axial configuration and is rated for 34A peak pulse current with 500W peak pulse power dissipation.

The SA9.0A B0G is currently 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 SA9.0A B0G are identified based on electrical and mechanical parameter equivalence. The critical parameters that determine substitution eligibility are:

• Voltage Rating: Reverse standoff voltage of 9V, breakdown voltage minimum of 10V, and clamping voltage maximum of 15.4V
• Current Handling: Peak pulse current of 34A at 10/1000µs pulse duration
• Power Dissipation: Peak pulse power rating of 500W
• Package Configuration: DO-204AC (DO-15) through-hole axial package
• Device Type: Unidirectional Zener TVS diode with single channel
• Temperature Range: Operating junction temperature range of -55°C to 175°C
• Compliance: RoHS3 compliance and REACH unaffected status

Parts meeting all these electrical and mechanical specifications are classified as direct equivalents and may be substituted without circuit redesign.

Parameter Comparison

Engineering Selection Recommendations

The SA9.0A A0G is a direct electrical and mechanical equivalent to the SA9.0A B0G. Both parts are manufactured by Taiwan Semiconductor Corporation and share identical electrical specifications across all critical parameters: voltage ratings, current handling, power dissipation, and operating temperature range. Both components are packaged in the DO-204AC (DO-15) through-hole axial configuration and are pin-compatible for direct board-level substitution.

The primary distinction between these parts is product status. The SA9.0A B0G is discontinued at DiGi Electronics, while the SA9.0A A0G maintains active product status with confirmed inventory availability (757 pieces in stock). Both parts maintain RoHS3 compliance and REACH unaffected status, ensuring regulatory alignment for current and future applications.

For new designs, repair operations, and production continuity, the SA9.0A A0G is the appropriate selection. No circuit modifications, thermal analysis adjustments, or performance re-qualification are required when substituting the SA9.0A A0G for the SA9.0A B0G.
