Key Parameters

Substitute Part Grouping Explanation

Substitution of the SA130C-B is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Voltage - Reverse Standoff (Typ): 130V
• Voltage - Breakdown (Min): 144V
• Voltage - Clamping (Max) @ Ipp: 209V
• Current - Peak Pulse (10/1000µs): minimum 2.4A
• Power - Peak Pulse: 500W
• Type: Zener
• Bidirectional Channels: 1

Mechanical Equivalence Criteria:

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

Compliance Criteria:

• RoHS Status: RoHS Compliant or equivalent
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

The SA130CA meets all electrical and mechanical requirements for direct substitution. The substitute maintains identical voltage specifications and clamping characteristics while providing a higher peak pulse current rating (2.5A versus 2.4A), ensuring compatibility in existing circuit designs. The substitute is classified as active product status, providing long-term availability and supply chain continuity.

Parameter Comparison

Engineering Selection Recommendations

SA130CA as Direct Substitute:

The SA130CA is a direct electrical and mechanical substitute for the SA130C-B. Both components share identical voltage specifications (130V reverse standoff, 144V breakdown minimum, 209V clamping maximum) and package configuration (DO-204AC through-hole axial). The SA130CA provides a peak pulse current rating of 2.5A, which exceeds the SA130C-B requirement of 2.4A, ensuring adequate performance margin in transient suppression applications.

Product Status Advantage:

The SA130CA holds active product status from Taiwan Semiconductor Corporation, providing assured long-term availability and supply chain stability. The SA130C-B is classified as obsolete, making the SA130CA the appropriate selection for new designs and ongoing production requirements.

Compliance Alignment:

Both components maintain equivalent RoHS compliance status (RoHS Compliant and ROHS3 Compliant respectively) and identical Moisture Sensitivity Level (MSL 1 - Unlimited), ensuring compatibility with standard manufacturing and storage protocols. Both components share identical ECCN (EAR99) and HTSUS (8541.10.0080) classifications.

Operating Temperature Consideration:

The SA130CA operating temperature range (-55°C to 175°C) is narrower than the SA130C-B range (-65°C to 175°C) at the lower temperature extreme. Applications requiring operation below -55°C require evaluation against specific system requirements.

Frequently Asked Questions (FAQ)

Q: Can SA130CA replace SA130C-B in existing designs?

A: Yes. The SA130CA provides electrical equivalence across all critical parameters: identical 130V reverse standoff voltage, 144V breakdown minimum, and 209V clamping voltage. Both components use the DO-204AC (DO-15) through-hole axial package, enabling direct mechanical substitution on printed circuit boards without layout modifications.

Q: What is the difference in peak pulse current between these parts?

A: The SA130CA provides 2.5A peak pulse current compared to the SA130C-B specification of 2.4A. This represents a 4.2% increase in current handling capability, providing additional performance margin for transient suppression without reducing circuit protection effectiveness.

Q: Are there packaging differences between SA130C-B and SA130CA?

A: Both components use identical DO-204AC (DO-15) axial through-hole packaging. The SA130C-B is supplied in standard packaging, while the SA130CA is supplied in Tape & Reel (TR) format. This difference affects procurement and assembly processes but does not impact component electrical or mechanical performance.

Q: Does the operating temperature range difference affect substitution?

A: The SA130CA minimum operating temperature is -55°C compared to -65°C for the SA130C-B. For applications operating within the -55°C to 175°C range, the SA130CA is fully qualified. Applications requiring operation below -55°C require specific evaluation against system temperature requirements.

Q: Are both components RoHS compliant?

A: Yes. The SA130C-B is RoHS Compliant, and the SA130CA is ROHS3 Compliant. Both components meet RoHS requirements and are suitable for applications with RoHS compliance mandates. Both maintain Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions.

Q: What is the basis for substitution compatibility?

A: Substitution is based on strict equivalence across voltage specifications (reverse standoff, breakdown, and clamping), current ratings, power dissipation, package type, and mounting configuration. The SA130CA meets or exceeds all electrical requirements while maintaining identical mechanical compatibility.
