SMLJ6.0CE3/TR13 Transient Voltage Suppressors (TVS)

Part Overview

The SMLJ6.0CE3/TR13 is a surface mount transient voltage suppressor (TVS) diode manufactured by Microchip Technology, rated for 6V Reverse Standoff voltage with an 11.4V maximum clamping voltage. The device operates across the temperature range of -55°C to 150°C and is packaged in DO-214AB (SMC) format on Tape & Reel. As an active product with RoHS3 compliance and REACH Unaffected status, equivalent substitute models exist to provide component availability across multiple manufacturers when supply constraints or procurement requirements necessitate alternative sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the SMLJ6.0CE3/TR13 is determined by the following critical electrical and mechanical parameters:

Voltage Rating Match: All substitute parts maintain the same 6V Reverse Standoff voltage and 6.67V minimum breakdown voltage, ensuring identical circuit protection thresholds.

Package Compatibility: All substitutes are housed in DO-214AB/SMC surface mount package format, enabling direct footprint compatibility on PCBs designed for the original component.

Temperature Range Compliance: Substitute parts operate within temperature ranges that encompass or match the original specification (-55°C to 150°C), ensuring functional operation across the same thermal environment.

Type Consistency: All substitute parts are zener-type, single-channel bidirectional TVS diodes, maintaining identical functional characteristics.

Regulatory Compliance: All substitute parts carry RoHS3 compliance and REACH Unaffected status, matching the regulatory requirements of the original component.

The following electrical parameters show variation among substitutes but remain within acceptable ranges for general purpose TVS applications: voltage clamping (10.3V to 11.4V), peak pulse current (145.6A to 291.3A), and peak pulse power (300W to 3kW).

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain active product status and full compliance with RoHS3 and REACH regulations, confirming their suitability for contemporary applications. The SMCJ6.0CA variants (MDD, Diodes Incorporated, Micro Commercial Co) and SMCJ6V0CA (Fairchild Semiconductor) provide equivalent functionality with lower peak pulse power dissipation (1500W) and reduced peak pulse current (145.6A to 145.7A), making them suitable for applications where the original component's 263.2A peak pulse rating is not fully utilized.

The SMDJ6.0CA (Alpha & Omega Semiconductor Inc.) and SMLJ6.0CA (Bourns Inc.) both deliver higher peak pulse power (3000W) and peak pulse current (291.3A), providing enhanced transient protection capability compared to the original part. The SMLJ6.0CA from Bourns represents a notable alternative, offering the same manufacturer series designation as the original while delivering superior power dissipation characteristics.

Selection of substitute parts should be based on application requirements for peak pulse current and power dissipation capacity, with all candidates providing equivalent voltage protection thresholds and compatible package formats.

Frequently Asked Questions (FAQ)

Q: Can SMCJ6.0CA variants be used as direct drop-in replacements for SMLJ6.0CE3/TR13?

A: Yes. The SMCJ6.0CA parts from MDD, Diodes Incorporated, and Micro Commercial Co share identical voltage ratings (6V Reverse Standoff, 6.67V breakdown) and DO-214AB/SMC package format. The primary difference is lower peak pulse power (1500W versus 300W), making them suitable for applications where transient energy is within the 1500W range.

Q: What is the difference between the SMLJ6.0CA and SMDJ6.0CA substitutes?

A: Both SMLJ6.0CA (Bourns) and SMDJ6.0CA (Alpha & Omega Semiconductor) deliver identical electrical performance with 3000W peak pulse power and 291.3A peak pulse current. The distinction is manufacturer; both are valid alternatives depending on procurement availability and supplier qualification requirements.

Q: Does temperature range variation affect part substitution?

A: Temperature range variation is acceptable for substitution. The SMCJ6.0CA-TP variant operates up to 175°C, exceeding the original specification of 150°C, offering expanded thermal capability. The SMCJ6.0CA (MDD) operates from -50°C (versus -55°C), a minor limitation appropriate for applications above -50°C.

Q: Are all substitute parts in the same package format?

A: Yes. All substitute parts use the DO-214AB/SMC surface mount package, providing footprint compatibility with the original design. Tape & Reel packaging availability varies by manufacturer but does not affect electrical interchangeability.

Q: What regulatory compliance should I verify when substituting parts?

A: All listed substitute parts carry RoHS3 compliance and REACH Unaffected status, matching the regulatory profile of the original SMLJ6.0CE3/TR13. No additional compliance verification is required for regulatory substitution.
