SA150CAHB0G Equivalent & Substitute Parts

Part Overview

The SA150CAHB0G is a transient voltage suppressor (TVS) diode manufactured by Taiwan Semiconductor Corporation, designed for protection against transient voltage spikes in electronic circuits. This component features a 150V reverse standoff voltage with a 243V maximum clamping voltage and 2.1A peak pulse current capability in a through-hole DO-204AC (DO-15) axial package. The part is qualified to AEC-Q101 automotive standards and is ROHS3 compliant.

The SA150CAHB0G is currently discontinued at DiGi Electronics. Identifying equivalent substitute parts with identical electrical and mechanical specifications is necessary to maintain design continuity and ensure component availability for production and repair applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SA150CAHB0G are identified based on strict equivalence across all critical electrical and mechanical parameters. The substitution logic requires exact matching of the following specifications:

• Voltage - Reverse Standoff (Typ): 150V
• Voltage - Breakdown (Min): 167V
• Voltage - Clamping (Max) @ Ipp: 243V
• Current - Peak Pulse (10/1000µs): 2.1A
• Power - Peak Pulse: 500W
• Operating Temperature Range: -55°C to 175°C (TJ)
• Package / Case: DO-204AC, DO-15, Axial
• Mounting Type: Through Hole
• Grade: Automotive
• Qualification: AEC-Q101
• RoHS Status: ROHS3 Compliant

Parts meeting all these criteria are classified as direct electrical and mechanical equivalents suitable for one-to-one replacement in circuit designs.

Parameter Comparison

Engineering Selection Recommendations

The SA150CAHA0G is a direct equivalent substitute for the SA150CAHB0G. Both components are manufactured by Taiwan Semiconductor Corporation within the SA series and share identical electrical specifications across all critical parameters: 150V reverse standoff voltage, 167V minimum breakdown voltage, 243V maximum clamping voltage, and 2.1A peak pulse current.

Both parts are qualified to AEC-Q101 automotive standards, carry ROHS3 compliance, and feature identical through-hole DO-204AC (DO-15) axial packaging. The operating temperature range, power dissipation capability, and moisture sensitivity classification are identical between the two parts.

The primary distinction is product status: the SA150CAHB0G is discontinued at DiGi Electronics, while the SA150CAHA0G maintains active status with confirmed inventory availability (1071 pieces in stock). For applications requiring the SA150CAHB0G, the SA150CAHA0G provides full functional and mechanical compatibility with no design modifications required.

Frequently Asked Questions (FAQ)

Q: Can the SA150CAHA0G be used as a direct replacement for the SA150CAHB0G?

A: Yes. The SA150CAHA0G is a direct equivalent substitute. All electrical parameters, mechanical specifications, automotive qualifications, and compliance certifications are identical. No circuit modifications or design changes are required.

Q: Are there any differences in the package or mounting between these parts?

A: No. Both the SA150CAHB0G and SA150CAHA0G use identical through-hole DO-204AC (DO-15) axial packaging. They are mechanically interchangeable on printed circuit boards designed for either component.

Q: What is the significance of the product status difference?

A: The SA150CAHB0G is discontinued at DiGi Electronics, indicating it is no longer available through that distribution channel. The SA150CAHA0G maintains active status with current inventory availability, making it the practical choice for new procurement and production applications.

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both the SA150CAHB0G and SA150CAHA0G are qualified to AEC-Q101 automotive standards and carry the Automotive grade designation. They are suitable for automotive and industrial applications requiring transient voltage suppression.

Q: Are the RoHS and REACH compliance statuses identical?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected. They meet the same environmental and regulatory requirements for component selection in regulated applications.

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

A: Substitution eligibility is determined by exact matching of reverse standoff voltage (150V), breakdown voltage (167V minimum), clamping voltage (243V maximum), peak pulse current (2.1A), and peak pulse power (500W). The SA150CAHA0G matches all these specifications.

Q: Is the moisture sensitivity level the same for both parts?

A: Yes. Both parts carry MSL 1 (Unlimited) classification, indicating they have unlimited shelf life and require no special moisture control during storage or handling.
