Substitute Part Grouping Explanation

Substitution of the P4SMA70CA TR13 is determined by strict equivalence across the following critical electrical and mechanical parameters:

• Voltage - Reverse Standoff (Typ): 70V
• Voltage - Breakdown (Min): 77.8V
• Voltage - Clamping (Max) @ Ipp: 113V
• Current - Peak Pulse (10/1000µs): 4.6A
• Power - Peak Pulse: 400W
• Package / Case: DO-214AC, SMA
• Mounting Type: Surface Mount
• Operating Temperature Range: -55°C ~ 150°C (TJ)
• Bidirectional Channels: 1
• Type: Zener

The SMAJ70CA-13-F from Diodes Incorporated meets all specified electrical and mechanical parameters, establishing it as a direct functional equivalent for the obsolete P4SMA70CA TR13.

Parameter Comparison

Engineering Selection Recommendations

The SMAJ70CA-13-F is the qualified substitute for the obsolete P4SMA70CA TR13. This part is manufactured by Diodes Incorporated, an active supplier with current production status, ensuring long-term availability and supply chain continuity.

The SMAJ70CA-13-F carries ROHS3 compliance and REACH unaffected status, meeting modern regulatory requirements. Both parts share identical electrical specifications and package geometry, enabling direct replacement in existing designs without circuit modification.

The primary distinction is packaging format: the original part was supplied in bulk, while the substitute is available in Tape & Reel (TR) format, which is standard for automated assembly processes and provides superior inventory management for production environments.

Frequently Asked Questions (FAQ)

Q: Can the SMAJ70CA-13-F be used as a direct replacement for the P4SMA70CA TR13?

A: Yes. Both parts are electrically and mechanically identical across all critical parameters: 70V reverse standoff voltage, 113V clamping voltage, 4.6A peak pulse current, 400W peak pulse power, and SMA package configuration. No circuit redesign is required.

Q: What is the difference between the P4SMA70CA TR13 and SMAJ70CA-13-F?

A: The primary difference is manufacturer and product status. The P4SMA70CA TR13 (Central Semiconductor Corp) is obsolete. The SMAJ70CA-13-F (Diodes Incorporated) is an active product with current production. Packaging format differs: bulk versus Tape & Reel. Electrical and mechanical specifications are identical.

Q: Is the SMAJ70CA-13-F compatible with existing PCB layouts designed for the P4SMA70CA TR13?

A: Yes. Both parts use the DO-214AC SMA package with identical pin configuration and footprint. PCB layouts require no modification.

Q: What compliance certifications does the SMAJ70CA-13-F carry?

A: The SMAJ70CA-13-F is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: Why is the SMAJ70CA-13-F supplied in Tape & Reel format?

A: Tape & Reel (TR) packaging is the industry standard for surface mount components in automated assembly environments. It provides improved handling, reduced damage risk, and better inventory tracking compared to bulk packaging.
