SMCJ130CA-13 Equivalent & Substitute Parts

Part Overview

The SMCJ130CA-13 is a transient voltage suppressor (TVS) diode manufactured by Diodes Incorporated, designed for general-purpose overvoltage protection in surface mount applications. This component features a 130V reverse standoff voltage with 209V maximum clamping voltage and 7.2A peak pulse current capability in a DO-214AB (SMC) package. The part is currently discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives from active manufacturers to maintain design continuity and supply chain reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SMCJ130CA-13 is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria (Must Match):

• Voltage - Reverse Standoff: 130V
• Voltage - Breakdown (Min): 144V
• Voltage - Clamping (Max) @ Ipp: 209V
• Package / Case: DO-214AB (SMC)
• Mounting Type: Surface Mount
• Type: Zener
• Bidirectional Channels: 1

Secondary Consideration (Allowable Variation):

• Current - Peak Pulse (10/1000µs): Minimum 7.2A (higher values acceptable)
• Power - Peak Pulse: Minimum 1500W (higher values acceptable)
• Operating Temperature Range: Minimum -55°C to 150°C (extended ranges acceptable)

Substitute parts are grouped into two categories: direct electrical equivalents with identical peak pulse specifications, and higher-rated alternatives with increased current and power handling capability while maintaining identical voltage parameters and package form factor.

Parameter Comparison

Engineering Selection Recommendations

Direct Electrical Equivalents (Identical Voltage & Power Ratings):

SMCJ130CA (Meritek) and SMCJ130CA-TP (Micro Commercial Co) provide direct substitution with matching 130V standoff, 209V clamping, and 1500W peak pulse specifications. Both are ROHS3 compliant and in active production. SMCJ130CA-TP offers extended operating temperature to 175°C. These parts maintain identical electrical performance and package form factor.

Higher-Rated Alternatives (Increased Current & Power Handling):

SMDJ130CA (Alpha & Omega Semiconductor Inc.), SMDJ130CA-T7 (Littelfuse Inc.), and SMLJ130CA (Bourns Inc.) provide 3000W peak pulse capability with 14.4A peak current while maintaining identical voltage parameters. These are suitable for applications requiring enhanced transient energy absorption. SMDJ130CA-T7 extends operating temperature to -65°C.

Enhanced Performance Alternative:

5.0SMDJ130CA (MDE Semiconductor Inc) and 5.0SMDJ130CA-T7 (Littelfuse Inc.) deliver 5000W peak pulse with 24A peak current, providing maximum transient protection margin. 5.0SMDJ130CA-T7 supports -65°C minimum operating temperature.

Non-Recommended Substitute:

SMCJ130CA-TR (STMicroelectronics) exhibits 265V maximum clamping voltage, exceeding the original 209V specification. This elevated clamping voltage falls outside the allowed parameter range and is not suitable for direct substitution.

All recommended alternatives are ROHS3 compliant and in active production status, ensuring long-term supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can SMCJ130CA-TP replace SMCJ130CA-13 in existing designs?

A: Yes. SMCJ130CA-TP maintains identical voltage specifications (130V standoff, 209V clamping) and power rating (1500W), with matching DO-214AB (SMC) package. The extended temperature range to 175°C provides additional operational margin.

Q: What is the difference between SMCJ130CA and SMDJ130CA substitutes?

A: Both maintain identical voltage parameters (130V/209V). SMDJ130CA provides 3000W peak pulse versus 1500W for SMCJ130CA, offering doubled transient energy absorption capability. Both use DO-214AB (SMC) packaging and are pin-compatible.

Q: Are 5.0SMDJ130CA parts suitable for direct replacement?

A: 5.0SMDJ130CA parts maintain identical voltage specifications and package form factor but deliver 5000W peak pulse (versus 1500W original). These are suitable only if the application can accommodate higher transient energy dissipation without thermal or circuit interaction issues.

Q: Why is SMCJ130CA-TR not recommended?

A: SMCJ130CA-TR specifies 265V maximum clamping voltage, exceeding the original 209V parameter. This deviation violates substitution criteria and may cause circuit compatibility issues.

Q: What packaging options are available?

A: All substitute parts use DO-214AB (SMC) surface mount package, maintaining identical PCB footprint and reflow soldering compatibility with the original SMCJ130CA-13.

Q: Are all recommended substitutes RoHS compliant?

A: Yes. All active substitute parts listed are ROHS3 compliant, whereas the original SMCJ130CA-13 is RoHS non-compliant. This compliance upgrade is beneficial for new designs and regulatory requirements.

Q: What is the inventory status of substitute parts?

A: SMCJ130CA (Meritek): 4369 pcs; SMCJ130CA-TP (Micro Commercial Co): 3770 pcs; SMDJ130CA (Alpha & Omega): 59495 pcs; SMLJ130CA (Bourns): 11223 pcs; 5.0SMDJ130CA (MDE): 22700 pcs; 5.0SMDJ130CA-T7 (Littelfuse): 1495 pcs; SMDJ130CA-T7 (Littelfuse): 2088 pcs. All are in active stock.
