SMDA12-6/TR13 Equivalent & Substitute Parts

Part Overview

The SMDA12-6/TR13 is a Transient Voltage Suppressor (TVS) diode manufactured by Microchip Technology, part of the TVSarray™ series. This surface-mount component provides transient voltage protection in general-purpose applications with a 12V reverse standoff voltage and 24V maximum clamping voltage. The device is classified as an active product and is available in 8-SOIC packaging with tape and reel distribution.

Substitute parts are identified when electrical characteristics, mechanical specifications, and packaging parameters remain identical across different manufacturing batches or distribution formats, ensuring direct functional equivalence in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both SMDA12-6/TR13 and SMDA12-6/TR7 are functionally equivalent TVS diodes with identical electrical and mechanical specifications. The primary distinction between these parts is regulatory compliance status.

SMDA12-6/TR13 is RoHS non-compliant and suitable for applications where RoHS compliance is not a requirement.

SMDA12-6/TR7 is ROHS3 compliant and is the appropriate selection for applications subject to RoHS (Restriction of Hazardous Substances) regulations, including European Union markets and regulated industries.

Both parts maintain identical performance characteristics across all electrical parameters, package specifications, and operating conditions. Selection between these substitutes depends solely on regulatory and compliance requirements of the target application and market jurisdiction.

Frequently Asked Questions (FAQ)

Q: Are SMDA12-6/TR13 and SMDA12-6/TR7 electrically interchangeable?

A: Yes. Both parts are identical in all electrical specifications including voltage ratings, current capacity, clamping characteristics, and capacitance values. They perform identically in circuit applications.

Q: What is the difference between SMDA12-6/TR13 and SMDA12-6/TR7?

A: The primary difference is RoHS compliance status. SMDA12-6/TR13 is RoHS non-compliant, while SMDA12-6/TR7 is ROHS3 compliant. All other specifications are identical.

Q: Can I use SMDA12-6/TR7 as a direct replacement for SMDA12-6/TR13?

A: Yes, SMDA12-6/TR7 is a direct substitute for SMDA12-6/TR13 with identical electrical and mechanical characteristics. The ROHS3 compliance of SMDA12-6/TR7 makes it suitable for regulated applications.

Q: Do these parts have the same package dimensions?

A: Yes. Both parts use the 8-SOIC package with 0.154" (3.90mm) width. They are mechanically identical and compatible with the same PCB footprints and assembly processes.

Q: What does the "TR" designation in the part number indicate?

A: The "TR" designation indicates tape and reel packaging format, which is standard for surface-mount component distribution. The numbers following "TR" (13 and 7) represent different tape reel specifications or manufacturing batches.

Q: Are there any temperature or environmental differences between these parts?

A: No. Both parts operate across the identical temperature range of -55°C to 150°C (TJ) and have the same moisture sensitivity level (MSL 1 - Unlimited).

Q: Which part should I select for new designs?

A: For new designs, SMDA12-6/TR7 is the recommended selection due to ROHS3 compliance, which aligns with current regulatory standards and environmental requirements across most markets.
