SMBJ17CA-13 Equivalent & Substitute Parts
Part Overview
The SMBJ17CA-13 is a transient voltage suppressor (TVS) diode manufactured by Diodes Incorporated, designed for general-purpose overvoltage protection in surface-mount applications. This bidirectional Zener diode operates with a 17V reverse standoff voltage and provides 27.6V maximum clamping voltage at peak pulse current of 21.7A. The part is currently discontinued at DiGi Electronics, making equivalent substitutes necessary for ongoing production and maintenance applications.

Engineering Selection Recommendations
Primary Substitute: SMBJ17CA-13-F (Diodes Incorporated)
This part is the direct equivalent from the original manufacturer with identical electrical specifications and packaging. It is currently in active production status with ROHS3 compliance, making it the preferred choice for new designs and production continuity.
Secondary Substitutes:
SMBJ17CA (Meritek) and SMBJ17CA-TP (Micro Commercial Co) are functionally equivalent alternatives with active product status and ROHS3 compliance. Both maintain all critical electrical parameters within specification.
Automotive-Grade Alternative: SZ1SMB17CAT3G (Littelfuse Inc.)
This part meets AEC-Q101 automotive qualification standards and extends the lower operating temperature range to -65°C. Selection of this part is appropriate for applications requiring automotive-grade components or extended low-temperature performance.
All substitute parts are ROHS3 compliant, addressing the non-compliance status of the original SMBJ17CA-13.
Frequently Asked Questions (FAQ)
Q: Can SMBJ17CA-13-F be used as a direct replacement for SMBJ17CA-13?
A: Yes. SMBJ17CA-13-F is manufactured by Diodes Incorporated and maintains identical electrical specifications: 17V reverse standoff, 18.9V minimum breakdown, 27.6V maximum clamping, and 21.7A peak pulse current. The primary difference is packaging format (Tape & Reel) and ROHS3 compliance status.
Q: What is the difference between SMBJ17CA from Meritek and the original Diodes Incorporated part?
A: The Meritek SMBJ17CA maintains all critical electrical parameters. Peak pulse current is specified as 21.74A versus 21.7A, a difference within normal manufacturing tolerance. Both use identical DO-214AA (SMB) packaging.
Q: Why is SZ1SMB17CAT3G listed as a substitute if it has different temperature specifications?
A: SZ1SMB17CAT3G maintains all critical electrical parameters for voltage suppression (17V standoff, 27.6V clamping, 21.7A peak current). The extended lower temperature range (-65°C versus -55°C) and automotive qualification make it suitable for applications requiring enhanced environmental performance. The upper temperature limit remains at 150°C, matching the original specification.
Q: Are all substitute parts available in Tape & Reel packaging?
A: Yes. All listed substitutes are supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes.
Q: What compliance advantage do the substitute parts offer?
A: SMBJ17CA-13-F, SMBJ17CA (Meritek), SMBJ17CA-TP, and SZ1SMB17CAT3G are all ROHS3 compliant, addressing the RoHS non-compliance status of the original SMBJ17CA-13. This compliance is required for many production environments and regulatory jurisdictions.
