SMBJ26CA-13 Equivalent & Substitute Parts

Part Overview

The SMBJ26CA-13 is a Transient Voltage Suppressor (TVS) diode manufactured by Diodes Incorporated, rated for 26V reverse standoff voltage with a 42.1V maximum clamping voltage. This surface mount component in DO-214AA (SMB) package is designed for general-purpose transient voltage protection applications. The part is currently discontinued at DiGi Electronics, making equivalent substitutes necessary for ongoing procurement and design continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the SMBJ26CA-13 is determined by strict equivalence across the following electrical and mechanical parameters:

• Voltage - Reverse Standoff (Typ): 26V
• Voltage - Breakdown (Min): 28.9V
• Voltage - Clamping (Max) @ Ipp: 42.1V
• Current - Peak Pulse (10/1000µs): 14.2A ± tolerance
• Power - Peak Pulse: 600W
• Package / Case: DO-214AA, SMB
• Mounting Type: Surface Mount
• Bidirectional Channels: 1
• Type: Zener

All substitute parts listed maintain these core electrical specifications within acceptable manufacturing tolerances. Packaging format (tape & reel, cut tape, or bulk) does not affect electrical equivalence but may impact procurement and assembly workflows.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: SMBJ26CA-13-F (Diodes Incorporated)

This part is the direct equivalent from the original manufacturer with identical electrical specifications and operating temperature range. It is currently in active production status with ROHS3 compliance, making it the preferred choice for new designs and replacements requiring regulatory compliance.

Alternative Substitutes:

SMBJ26CA-TP (Micro Commercial Co) offers an extended operating temperature range (-55°C ~ 175°C) compared to the original part, providing additional thermal margin for applications in elevated temperature environments. ROHS3 compliant and actively produced.

SMBJ26CA-TR (STMicroelectronics) maintains the original operating temperature specification with a marginally higher peak pulse current rating (14.9A vs 14.2A). ROHS3 compliant and actively produced.

TV06B260JB-G (Comchip Technology) provides electrical equivalence with a peak pulse current of 14.25A. ROHS3 compliant and actively produced. Operating temperature range is not specified in available documentation.

SMBJ26CA (EVVO Semi) is manufacturer-recommended as a general substitute with extended lower temperature rating (-65°C ~ 150°C). Peak pulse current is 14.3A. ROHS3 compliant and actively produced with high inventory availability.

All substitute parts share identical package format (DO-214AA, SMB), mounting type (surface mount), and core voltage specifications, ensuring direct functional replacement in existing PCB layouts.

Frequently Asked Questions (FAQ)

Q: Can SMBJ26CA-13 be replaced with any of the listed substitutes without circuit modification?

A: Yes. All listed substitutes maintain identical voltage specifications (26V reverse standoff, 28.9V breakdown minimum, 42.1V clamping maximum) and package format (DO-214AA, SMB). Peak pulse current variations (14.2A to 14.9A) fall within acceptable tolerance for general-purpose transient suppression applications. No circuit modifications are required.

Q: What is the difference between SMBJ26CA-13-F and SMBJ26CA-13?

A: SMBJ26CA-13-F is the active production equivalent from Diodes Incorporated with identical electrical and thermal specifications. The primary difference is product status: SMBJ26CA-13 is discontinued, while SMBJ26CA-13-F is actively manufactured. SMBJ26CA-13-F also carries ROHS3 compliance versus the non-compliant status of the original part.

Q: Does operating temperature range affect substitution compatibility?

A: Operating temperature range does not affect electrical equivalence for transient suppression function. However, it indicates the thermal environment in which the part maintains specified performance. SMBJ26CA-TP (-55°C ~ 175°C) and SMBJ26CA (-65°C ~ 150°C) offer extended thermal specifications compared to the original -55°C ~ 150°C range, providing additional design margin in temperature-sensitive applications.

Q: Are there packaging format differences among the substitutes?

A: All substitutes use the same DO-214AA (SMB) package for surface mount assembly. Packaging format variations (tape & reel, cut tape, bulk) relate to procurement and handling but do not affect electrical performance or PCB compatibility.

Q: Which substitute offers the best inventory availability?

A: SMBJ26CA (EVVO Semi) has the highest reported inventory at 55,200 pieces. SMBJ26CA-13-F (Diodes Incorporated) has 23,522 pieces available. TV06B260JB-G (Comchip Technology) has 12,644 pieces. SMBJ26CA-TP (Micro Commercial Co) has 4,400 pieces. SMBJ26CA-TR (STMicroelectronics) has 2,800 pieces.

Q: Is RoHS compliance a requirement for substitution?

A: RoHS compliance is a regulatory and procurement consideration, not an electrical substitution criterion. The original SMBJ26CA-13 is RoHS non-compliant. All listed substitutes are ROHS3 compliant, which may be required for new designs or applications subject to environmental regulations. Compliance status should be verified against your specific design and market requirements.
