Key Parameters

Substitute Part Grouping Explanation

Substitution of the P4SMA100CA TR13 is determined by strict equivalence across the following critical parameters:

• Voltage Rating: Reverse standoff voltage of 100V, breakdown minimum of 111V, and maximum clamping voltage of 162V must be maintained
• Current Handling: Peak pulse current of 2.5A (10/1000µs waveform) and peak pulse power of 400W
• Package Compatibility: DO-214AC / SMA surface mount package required for PCB footprint compatibility
• Electrical Characteristics: Single bidirectional channel, Zener-type TVS diode for general-purpose protection

The SMAJ100CA from MDD meets all specified electrical and mechanical parameters, providing direct functional equivalence with identical voltage ratings, current capacity, and package form factor.

Parameter Comparison

Engineering Selection Recommendations

The SMAJ100CA is a direct functional equivalent for the obsolete P4SMA100CA TR13. Selection of the SMAJ100CA is supported by:

• Electrical Equivalence: Identical voltage ratings (100V standoff, 111V breakdown minimum, 162V clamping maximum) and current specifications (2.5A peak pulse, 400W peak power)
• Package Compatibility: Both components use the DO-214AC / SMA surface mount package, ensuring PCB footprint and assembly process compatibility
• Active Product Status: The SMAJ100CA is currently in active production, providing supply chain continuity and long-term availability
• Compliance: ROHS3 compliance of the SMAJ100CA meets modern environmental and regulatory requirements
• Reliability: Both components share identical moisture sensitivity classification (MSL 1), indicating equivalent handling and storage requirements

Frequently Asked Questions (FAQ)

Q: Can the SMAJ100CA be used as a direct replacement for the P4SMA100CA TR13 in existing designs?

A: Yes. The SMAJ100CA provides electrical and mechanical equivalence across all specified parameters, including voltage ratings, current capacity, and SMA package form factor. No circuit modifications are required.

Q: Are there any differences in operating temperature range between these parts?

A: The P4SMA100CA TR13 operates from -55°C to 150°C, while the SMAJ100CA operates from -50°C to 150°C. The SMAJ100CA has a slightly higher minimum operating temperature. Verify this difference is acceptable for your application's thermal requirements.

Q: What is the significance of the obsolete status of the P4SMA100CA TR13?

A: Obsolete status indicates the part is no longer manufactured by Central Semiconductor Corp. The SMAJ100CA, with active product status, ensures continued availability and supply chain reliability for new procurements and design revisions.

Q: Are moisture sensitivity and handling requirements the same?

A: Yes. Both components are classified as MSL 1 (Unlimited), indicating identical moisture sensitivity levels and equivalent handling, storage, and reflow requirements.

Q: Does the SMAJ100CA meet current regulatory compliance standards?

A: Yes. The SMAJ100CA is ROHS3 compliant, meeting current environmental and regulatory requirements for electronic components in regulated markets.
