SMLJ8.0CE3/TR13 Equivalent & Substitute Parts

Part Overview

The SMLJ8.0CE3/TR13 is a transient voltage suppressor (TVS) diode manufactured by Microchip Technology, designed for general-purpose transient voltage protection applications. This surface-mount device features an 8V reverse standoff voltage and a 15V maximum clamping voltage with 200A peak pulse current capability. The product maintains active status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1), making it suitable for industrial and commercial electronics applications requiring reliable overvoltage protection.

Alternative models are necessary to address component availability, supply chain requirements, performance optimization for specific circuit parameters, or cost considerations while maintaining functional equivalence within the transient voltage suppressor category.

Key Parameters

Substitute Part Grouping Explanation

Substitution of TVS diodes is determined by electrical parameter compatibility within defined tolerance bands. The primary substitution criteria for the SMLJ8.0CE3/TR13 are:

Critical Parameters for Substitution:

• Reverse Standoff Voltage: 8V nominal
• Breakdown Voltage (Minimum): 8.89V or higher
• Clamping Voltage (Maximum): Must not exceed the circuit's maximum tolerable voltage
• Peak Pulse Current: Must meet or exceed the application's transient current requirements
• Operating Temperature Range: Must span -55°C to 150°C minimum
• Package Type: Surface mount, DO-214AB or equivalent SMC package
• Compliance: ROHS3 Compliant, RoHS Unaffected or equivalent

Substitute parts are grouped based on matching these electrical and mechanical specifications while accommodating minor variations in clamping voltage and peak pulse current that do not compromise circuit protection functionality.

Parameter Comparison

Engineering Selection Recommendations

SMCJ8.0CA-13-F (Diodes Incorporated): This substitute provides matching 8V reverse standoff voltage and 8.89V minimum breakdown voltage with slightly lower clamping voltage (13.6V vs. 15V), offering enhanced protection margins. Peak pulse current of 110.3A with 1500W peak power dissipation exceeds the original 200A specification in terms of power handling. All compliance certifications align with the main part: ROHS3 Compliant, MSL 1, REACH Unaffected. Product status is active with 787 units in stock.

SMCJ8.0CA (Taiwan Semiconductor Corporation): This substitute maintains identical 8V reverse standoff and 8.89V breakdown specifications with equivalent 13.6V clamping voltage. Peak pulse current of 115A and 1500W power handling provide suitable transient protection. ROHS3 compliance and MSL 1 rating match the original part. Higher inventory availability (84100 units) supports supply chain requirements. Product status is active.

SMCJ11CA-13-F (Diodes Incorporated): This substitute operates at 11V reverse standoff voltage with 12.2V minimum breakdown, representing a higher voltage variant unsuitable for direct 8V standoff applications. Included for reference only; electrical parameter mismatch precludes use as a primary equivalent.

Frequently Asked Questions (FAQ)

Q: Can SMCJ8.0CA-13-F directly replace the SMLJ8.0CE3/TR13?

A: Yes, with circuit verification. The SMCJ8.0CA-13-F matches the 8V reverse standoff voltage and 8.89V breakdown voltage specifications. The lower clamping voltage (13.6V vs. 15V) provides tighter voltage regulation, which benefits circuits sensitive to overvoltage transients. Peak pulse current (110.3A) is lower than the original 200A specification; verify the application's transient current does not exceed 110.3A before substitution.

Q: What is the primary difference between SMCJ8.0CA and SMCJ8.0CA-13-F?

A: Both parts share identical electrical specifications (8V standoff, 13.6V clamping, 8V/115A and 8V/110.3A peak pulse current respectively). The primary difference is manufacturer (Taiwan Semiconductor Corporation vs. Diodes Incorporated) and packaging notation (SMC vs. SMC with -13-F suffix). Both support surface-mount assembly in DO-214AB packages.

Q: Why is the SMCJ11CA-13-F listed if it cannot replace the SMLJ8.0CE3/TR13?

A: The SMCJ11CA-13-F is included for completeness in the product family analysis. Its 11V reverse standoff voltage addresses different circuit protection requirements than the 8V-rated main part. Do not use this part as a substitute for 8V protection circuits.

Q: Are all substitute parts available in Tape & Reel (TR) packaging?

A: The SMCJ8.0CA is listed without specific packaging notation. The SMCJ8.0CA-13-F and main part SMLJ8.0CE3/TR13 are confirmed available in Tape & Reel (TR) packaging. Verify packaging specifications with the supplier for high-volume production requirements.

Q: Do all parts meet the same compliance and environmental standards?

A: Yes. All listed parts maintain ROHS3 compliance, REACH Unaffected status, and Moisture Sensitivity Level 1 (Unlimited). All support the same operating temperature range (-55°C to 150°C), meeting industrial and commercial application requirements.
