SMBJ26AE3/TR13 Equivalent & Substitute Parts

Part Overview

The SMBJ26AE3/TR13 is a unidirectional Zener transient voltage suppressor (TVS) diode manufactured by Microchip Technology, designed for general-purpose overvoltage protection applications. This surface-mount component operates across a temperature range of -65°C to 150°C and is supplied in Tape & Reel packaging. The part maintains Active product status and is fully RoHS3 compliant with unlimited moisture sensitivity rating.

Equivalent and substitute parts are identified based on matching electrical performance characteristics, including reverse standoff voltage, breakdown voltage, clamping voltage, peak pulse current, and power dissipation ratings. Substitute components must maintain compatibility with the DO-214AA (SMB) package footprint and surface-mount assembly requirements.

Substitute Part Grouping Explanation

Substitute parts for the SMBJ26AE3/TR13 are classified based on electrical parameter equivalence and package compatibility. The primary substitution criteria are:

Critical Matching Parameters:

Voltage - Reverse Standoff: 26V
Voltage - Breakdown (Min): 28.9V
Voltage - Clamping (Max) @ Ipp: 42.1V (±0.2V tolerance acceptable)
Current - Peak Pulse (10/1000µs): 14.2A (±0.7A tolerance acceptable)
Power - Peak Pulse: 600W
Package / Case: DO-214AA or SMB equivalent
Mounting Type: Surface Mount

Direct Equivalents maintain all electrical parameters within specified tolerances and use identical or functionally equivalent packaging.

Similar Substitutes maintain core voltage and power specifications but may exhibit minor variations in peak pulse current or clamping voltage within acceptable engineering margins. These parts are suitable for applications where the primary voltage protection function is the design requirement.

Engineering Selection Recommendations

Direct Substitutes (Highest Compatibility):

The SMBJ26A-13-F (Diodes Incorporated) and SMBJ26A-TR (STMicroelectronics) are direct electrical equivalents to the SMBJ26AE3/TR13. Both maintain identical voltage specifications (26V standoff, 28.9V breakdown, 42.1V clamping) and 600W peak pulse power rating. Both are Active products with ROHS3 compliance and unlimited moisture sensitivity. The SMBJ26A-13-F is available in higher inventory (416,200 units) with Cut Tape and Digi-Reel packaging options. The SMBJ26A-TR provides 7,039 units in stock with similar electrical performance and TRANSIL™ series designation.

The primary consideration between these direct substitutes is operating temperature range: the SMBJ26AE3/TR13 and SMBJ26A (EVVO Semi) support -65°C minimum, while SMBJ26A-13-F and SMBJ26A-TR are rated to -55°C minimum. For applications requiring extended low-temperature operation below -55°C, the Microchip original or EVVO Semi variant is required.

Similar Substitute (Reduced Performance):

The SACB26 (Littelfuse) maintains voltage equivalence but operates at reduced peak pulse current (11.1A versus 14.2A) and lower peak pulse power (500W versus 600W). This part is suitable for applications where the transient voltage suppression function is the primary requirement and peak pulse current demand does not exceed 11.1A. The SACB26 is Active, ROHS3 compliant, and available in 2,400 units.

Package Consideration:

The SMBJ26A (EVVO Semi) uses DO-214AC (SMA) package, which differs from the DO-214AA (SMB) footprint of the primary part. This package variant requires PCB layout modification and is not a direct mechanical substitute without redesign.

Frequently Asked Questions (FAQ)

Q: Can the SMBJ26A-13-F replace the SMBJ26AE3/TR13 in all applications?

A: The SMBJ26A-13-F is electrically equivalent for voltage protection specifications. However, the operating temperature minimum is -55°C versus -65°C for the original part. If the application operates below -55°C, the SMBJ26A-13-F is not suitable. For applications within -55°C to 150°C range, the SMBJ26A-13-F provides direct substitution with identical electrical performance.

Q: What is the difference between the SMBJ26A-TR and SMBJ26A-13-F?

A: Both parts are electrically equivalent with 26V standoff, 28.9V breakdown, and 42.1V clamping voltage. The SMBJ26A-TR is manufactured by STMicroelectronics with 14.9A peak pulse current and TRANSIL™ series branding. The SMBJ26A-13-F is manufactured by Diodes Incorporated with 14.2A peak pulse current. Both support -55°C to 150°C operating range and are ROHS3 compliant. Selection between these parts depends on manufacturer preference and inventory availability.

Q: Why is the SACB26 listed as a substitute if it has lower peak pulse current?

A: The SACB26 maintains the critical voltage protection parameters (26V standoff, 28.9V breakdown, 42.1V clamping) required for transient suppression. The reduced peak pulse current (11.1A versus 14.2A) and power rating (500W versus 600W) make it suitable for applications where transient energy is within the 500W limit. This part is classified as a similar substitute for designs with lower transient energy requirements.

Q: Can I use the SMBJ26A (EVVO Semi) as a direct replacement?

A: The SMBJ26A from EVVO Semi is electrically equivalent with 26V standoff, 28.9V breakdown, 42.1V clamping, and 14.3A peak pulse current. However, it uses DO-214AC (SMA) package instead of DO-214AA (SMB). This requires PCB footprint modification and is not a direct mechanical substitute. Use this part only if PCB layout can accommodate the SMA package footprint.

Q: What packaging options are available for substitutes?

A: The SMBJ26AE3/TR13 is supplied in Tape & Reel (TR) format. Direct substitutes SMBJ26A-13-F and SMBJ26A-TR are available in Cut Tape and Digi-Reel packaging. The SACB26 is available in Tape & Reel format. The SMBJ26A (EVVO Semi) is available in Cut Tape and Digi-Reel. Verify packaging format compatibility with assembly equipment before selection.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts (SMBJ26A-13-F, SACB26, SMBJ26A-TR, and SMBJ26A from EVVO Semi) are ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1), matching the compliance profile of the SMBJ26AE3/TR13.
