Key Parameters

Substitute Part Grouping Explanation

Substitution of the S2AA-13 is determined by electrical and mechanical parameter equivalence. The substitute part S2AA-13-F maintains identical electrical specifications across all critical parameters: reverse voltage rating, average rectified current, forward voltage drop, recovery speed, reverse leakage current, and junction capacitance. Both parts utilize the same package type (DO-214AC, SMA) and mounting technology (surface mount), ensuring mechanical and thermal compatibility. The substitution is based on matching these core parameters without deviation.

Parameter Comparison

Engineering Selection Recommendations

The S2AA-13-F serves as the direct functional equivalent to the S2AA-13. Both parts are manufactured by Diodes Incorporated and share identical electrical and mechanical specifications. The S2AA-13-F is currently in active production status, whereas the S2AA-13 is discontinued. Additionally, the S2AA-13-F carries ROHS3 compliance certification, whereas the original S2AA-13 is non-compliant. For new designs and ongoing production, the S2AA-13-F is the appropriate selection. The packaging difference (tape and reel for S2AA-13-F versus the original packaging specification) does not affect electrical or mechanical performance and is a standard supply format variation.

Frequently Asked Questions (FAQ)

Q: Can the S2AA-13-F be used as a direct replacement for the S2AA-13?

A: Yes. The S2AA-13-F is electrically and mechanically equivalent to the S2AA-13. All electrical parameters, including reverse voltage, forward current, forward voltage drop, recovery speed, reverse leakage, and capacitance are identical. Both use the same DO-214AC SMA package and surface mount technology.

Q: What is the difference between the S2AA-13 and S2AA-13-F?

A: The primary differences are product status and regulatory compliance. The S2AA-13 is discontinued at DiGi Electronics, while the S2AA-13-F is active. The S2AA-13-F is ROHS3 compliant, whereas the S2AA-13 is non-compliant. The S2AA-13-F is supplied in tape and reel packaging format.

Q: Are there any thermal or electrical performance differences between these parts?

A: No. Both parts have identical operating temperature ranges (-65°C to 150°C) and all electrical specifications. Thermal and electrical performance are equivalent.

Q: Does the tape and reel packaging of the S2AA-13-F affect compatibility?

A: No. Tape and reel is a supply format for automated assembly processes. It does not affect the component's electrical characteristics, mechanical fit, or performance in the circuit.

Q: Is the S2AA-13-F suitable for applications requiring RoHS compliance?

A: Yes. The S2AA-13-F is ROHS3 compliant, making it suitable for applications with RoHS requirements. The original S2AA-13 is not RoHS compliant.

Q: Can I use the S2AA-13-F in legacy designs originally specified for the S2AA-13?

A: Yes. The S2AA-13-F is a direct equivalent and can be used in any application originally designed for the S2AA-13 without circuit modifications or re-qualification.
