SMBJ130CA-13 Equivalent & Substitute Parts

Part Overview

The SMBJ130CA-13 is a Transient Voltage Suppressor (TVS) diode manufactured by Diodes Incorporated, designed for general-purpose transient voltage protection in surface-mount applications. This component features a 130V reverse standoff voltage with a 209V maximum clamping voltage and 2.9A peak pulse current capability in a DO-214AA (SMB) package. The part is currently discontinued at DiGi Electronics, making equivalent substitutes necessary for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SMBJ130CA-13 is determined by the following critical parameters:

• Voltage - Reverse Standoff (Typ): 130V
• Voltage - Breakdown (Min): 144V
• Voltage - Clamping (Max) @ Ipp: 209V
• Current - Peak Pulse (10/1000µs): 2.9A ± tolerance
• Power - Peak Pulse: 600W
• Package / Case: DO-214AA (SMB)
• Mounting Type: Surface Mount
• Bidirectional Channels: 1
• Operating Temperature Range: -55°C ~ 150°C

Substitute parts must maintain identical electrical specifications within standard manufacturing tolerances and use the same physical package to ensure direct PCB compatibility without layout modifications.

Parameter Comparison

Engineering Selection Recommendations

SMBJ130CA-13-F (Diodes Incorporated) is the primary direct substitute. This part maintains identical electrical specifications and is manufactured by the original equipment supplier. It is currently in active production status with ROHS3 compliance and significantly higher inventory availability (35,414 pcs vs. 682 pcs for the original part). The only difference is packaging format (Tape & Reel vs. bulk), which does not affect electrical performance or PCB compatibility.

SMBJ130CA (Meritek) serves as an alternative substitute with equivalent electrical performance. Peak pulse current specification is 2.87A compared to 2.9A, representing a 1.0% variance within acceptable manufacturing tolerances for this component class. This part is ROHS3 compliant and maintains active production status with substantial inventory (49,500 pcs). The Meritek variant is suitable for applications where the minor current specification variance is acceptable.

Both substitutes maintain the same DO-214AA (SMB) package footprint, operating temperature range, and voltage specifications required for direct replacement without circuit redesign.

Frequently Asked Questions (FAQ)

Q: Can SMBJ130CA-13-F be used as a direct replacement for SMBJ130CA-13?

A: Yes. SMBJ130CA-13-F is electrically and mechanically identical to SMBJ130CA-13. The primary difference is packaging format (Tape & Reel vs. bulk). Both parts are manufactured by Diodes Incorporated and share identical electrical specifications, package type (DO-214AA/SMB), and operating characteristics.

Q: What is the significance of the 2.87A vs. 2.9A peak pulse current difference between Diodes and Meritek variants?

A: The 0.03A difference represents a 1.0% variance and falls within standard manufacturing tolerances for TVS diodes in this category. Both specifications meet the 600W peak pulse power requirement and are functionally equivalent for general-purpose transient voltage suppression applications.

Q: Are there any compliance differences between the substitutes?

A: The original SMBJ130CA-13 is RoHS non-compliant. Both substitute parts (SMBJ130CA-13-F and SMBJ130CA) are ROHS3 compliant, making them suitable for applications requiring RoHS compliance. All three parts are REACH Unaffected and carry EAR99 export classification.

Q: Does the SMB package remain the same across all variants?

A: Yes. All three parts use the DO-214AA (SMB) surface-mount package. PCB footprint, land pattern, and mounting requirements are identical, enabling direct substitution without layout modifications.

Q: Which substitute should be selected for new designs?

A: SMBJ130CA-13-F is recommended for new designs due to active production status, ROHS3 compliance, and availability from the original manufacturer. SMBJ130CA (Meritek) is a viable alternative if supply constraints exist.
