• Power - Peak Pulse: 400W
• Package / Case: DO-214AC, SMA
• Mounting Type: Surface Mount
• Operating Temperature Range: -55°C ~ 150°C (TJ)

The SMAJ85CA-13-F from Diodes Incorporated meets all specified electrical and mechanical parameters, establishing it as a direct functional equivalent for the obsolete P4SMA85CA TR13.

Parameter Comparison

Engineering Selection Recommendations

The SMAJ85CA-13-F is the appropriate substitute for the obsolete P4SMA85CA TR13 based on the following factors:

• All critical electrical parameters match exactly: reverse standoff voltage, breakdown voltage, clamping voltage, peak pulse current, and peak pulse power.
• Package and mounting specifications are identical, ensuring direct board-level compatibility without layout modifications.
• The substitute part maintains the same operating temperature range, supporting equivalent thermal performance.
• The SMAJ85CA-13-F carries active product status, ensuring ongoing availability and supply chain support.
• The substitute part is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.

Frequently Asked Questions (FAQ)

Q: Can the SMAJ85CA-13-F be used as a direct replacement for the P4SMA85CA TR13?

A: Yes. The SMAJ85CA-13-F matches all specified electrical parameters (85V reverse standoff, 137V clamping voltage, 2.9A peak pulse current, 400W peak pulse power) and package specifications (DO-214AC, SMA surface mount). No circuit modifications or board redesign are required.

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

A: No performance differences exist within the specified operating parameters. Both parts are Zener-type TVS diodes with identical voltage ratings, current ratings, and power dissipation capabilities across the -55°C to 150°C operating temperature range.

Q: What is the significance of the SMAJ85CA-13-F being ROHS3 compliant?

A: ROHS3 compliance indicates the substitute part meets current European Union Restriction of Hazardous Substances regulations. This is relevant for applications subject to environmental and regulatory compliance requirements in regulated markets.

Q: Does the packaging format differ between these parts?

A: The P4SMA85CA TR13 is supplied in tape and reel format (TR13). The SMAJ85CA-13-F is available in tape and reel (TR) packaging. Both formats are standard for surface mount assembly processes and are compatible with automated pick-and-place equipment.

Q: Why is the original part listed as obsolete?

A: Obsolescence typically results from manufacturer discontinuation decisions based on market demand, product line consolidation, or transition to newer manufacturing processes. The SMAJ85CA-13-F from Diodes Incorporated provides equivalent functionality with active product status and ongoing manufacturer support.
