SA160A B0G Equivalent & Substitute Parts

Part Overview

The SA160A 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 160V reverse standoff voltage with a 259V maximum clamping voltage and 2A peak pulse current rating in a through-hole DO-204AC (DO-15) axial package. The SA160A B0G is currently discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives to maintain design continuity and ensure component availability for production and repair applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SA160A B0G is determined by strict equivalence across the following critical electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Voltage - Reverse Standoff (Typ): 160V
• Voltage - Breakdown (Min): 178V
• Voltage - Clamping (Max) @ Ipp: 259V
• Current - Peak Pulse (10/1000µs): 2A
• Power - Peak Pulse: 500W
• Operating Temperature Range: -55°C to 175°C (TJ)

Mechanical Equivalence Criteria:

• Package / Case: DO-204AC, DO-15, Axial
• Mounting Type: Through Hole
• Unidirectional Channels: 1

Compliance Equivalence Criteria:

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

Parts meeting all specified parameters within these categories are classified as direct functional equivalents and may be substituted without circuit redesign or performance degradation.

Parameter Comparison

Engineering Selection Recommendations

The SA160A A0G serves as a direct functional equivalent to the discontinued SA160A B0G. Both components are manufactured by Taiwan Semiconductor Corporation and share identical electrical specifications, mechanical packaging, and compliance certifications.

Selection Basis:

The SA160A A0G is currently in active product status with 992 pieces available in stock, compared to the SA160A B0G which is discontinued. The substitute part maintains full electrical equivalence across all critical parameters: 160V reverse standoff voltage, 178V minimum breakdown voltage, 259V maximum clamping voltage, and 2A peak pulse current. Both components are rated for identical operating temperature ranges (-55°C to 175°C junction temperature) and are housed in the same DO-204AC (DO-15) axial through-hole package.

Compliance certifications are equivalent: both parts are ROHS3 compliant, carry MSL rating of 1 (Unlimited), and are REACH unaffected. The SA160A A0G is suitable for direct substitution in all applications where the SA160A B0G was originally specified, with no circuit modifications required.

Frequently Asked Questions (FAQ)

Q: Can the SA160A A0G be used as a direct replacement for the SA160A B0G?

A: Yes. The SA160A A0G is a direct functional equivalent. All electrical parameters, mechanical specifications, and compliance certifications are identical. No circuit redesign or component repositioning is required.

Q: Are there any differences in the electrical performance between these two parts?

A: No. Both parts share identical voltage ratings (160V reverse standoff, 178V breakdown minimum, 259V clamping maximum), current ratings (2A peak pulse), power dissipation (500W peak pulse), and operating temperature range (-55°C to 175°C).

Q: Do both parts use the same package?

A: Yes. Both the SA160A B0G and SA160A A0G use the DO-204AC (DO-15) axial through-hole package. PCB layout and component placement remain unchanged.

Q: What is the difference between the part numbers SA160A B0G and SA160A A0G?

A: The difference lies in the suffix designation (B0G versus A0G). Both parts share the same base product number (SA160) and are manufactured by Taiwan Semiconductor Corporation. The suffix variation reflects internal manufacturing or date code tracking but does not affect electrical or mechanical specifications.

Q: Are both parts RoHS compliant?

A: Yes. Both the SA160A B0G and SA160A A0G are ROHS3 compliant and carry identical MSL rating of 1 (Unlimited). Both are REACH unaffected.

Q: What is the inventory status of the substitute part?

A: The SA160A A0G is currently in active product status with 992 pieces available in stock. The SA160A B0G is discontinued at DiGi Electronics.

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

A: Yes. The SA160A A0G can be substituted for the SA160A B0G without any design modifications, PCB layout changes, or performance impact. Both components are rated for identical operating conditions and general-purpose transient voltage suppression applications.
