SMLJ7.0CE3/TR13 Equivalent & Substitute Parts

Part Overview

The SMLJ7.0CE3/TR13 is a transient voltage suppressor (TVS) diode manufactured by Microchip Technology, designed for general-purpose overvoltage protection in surface-mount applications. This bidirectional Zener diode operates with a 7V reverse standoff voltage and provides 13.3V clamping at peak pulse current. The component is packaged in DO-214AB (SMC) format with tape and reel packaging for automated assembly. Product status is Active with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Equivalent and substitute parts are identified based on matching core electrical parameters: reverse standoff voltage, breakdown voltage, clamping voltage, and package type, while accounting for variations in peak pulse current and power dissipation ratings.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SMLJ7.0CE3/TR13 is determined by the following core electrical parameters:

Primary Matching Criteria:

• Reverse standoff voltage: 7V (Typ)
• Breakdown voltage minimum: 7.78V or equivalent
• Package type: DO-214AB (SMC) surface mount
• Bidirectional channels: 1
• Type: Zener diode

Secondary Variation Parameters (allowable differences):

• Clamping voltage (Max) @ Ipp: 12V to 13.3V range
• Peak pulse current: 125A to 250A range
• Peak pulse power: 300W to 3000W range
• Operating temperature: -55°C minimum to 150°C or higher maximum
• Manufacturer: Different manufacturers acceptable if electrical parameters align

All identified substitute parts meet the primary matching criteria. Variations in peak pulse current and power dissipation reflect different device series within the 7V Zener category, allowing selection based on specific application current handling requirements.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain Active product status and full RoHS3 compliance, ensuring long-term availability and regulatory conformance equivalent to the SMLJ7.0CE3/TR13.

SMCJ7.0CA (Taiwan Semiconductor Corporation): This substitute matches all primary electrical parameters with identical reverse standoff voltage (7V), breakdown voltage (7.78V), and operating temperature range (-55 to 150°C). The clamping voltage is 12V versus 13.3V on the main part, and peak pulse current is 131A versus 225.6A. This part is suitable for applications where lower current handling is acceptable. Inventory availability is high (84,400 pcs).

SMCJ7.0CA-TP (Micro Commercial Co): This tape and reel packaged variant offers extended operating temperature range to 175°C, matching the main part's packaging format. Reverse standoff voltage, breakdown voltage, and clamping voltage parameters align with the TSC variant. Peak pulse current is 125A. This option is appropriate for temperature-critical applications or when tape and reel format is required for automated assembly. Inventory is 3,858 pcs.

SMDJ7.0CA (Alpha & Omega Semiconductor Inc.): This substitute provides the highest peak pulse current (250A) and power dissipation (3000W) among all options, exceeding the main part's 225.6A and 300W ratings. Reverse standoff voltage and breakdown voltage match the main part. Clamping voltage is 12V. This part is suitable for high-current transient suppression applications. Inventory is 12,400 pcs.

Selection should be based on specific application requirements for peak pulse current handling, power dissipation capability, and operating temperature range, with all options providing equivalent voltage protection characteristics.

Frequently Asked Questions (FAQ)

Q: What determines if a TVS diode can substitute for the SMLJ7.0CE3/TR13?

A: The primary substitution criteria are: 7V reverse standoff voltage, 7.78V minimum breakdown voltage, DO-214AB (SMC) package type, and single bidirectional channel configuration. All identified substitutes meet these core requirements. Secondary parameters such as clamping voltage, peak pulse current, and power dissipation may vary within acceptable ranges depending on application requirements.

Q: Can I use SMCJ7.0CA in place of SMLJ7.0CE3/TR13 if my circuit requires 225.6A peak pulse current?

A: The SMCJ7.0CA is rated for 131A peak pulse current, which is lower than the 225.6A specification of the main part. If your application requires 225.6A or higher current handling, the SMDJ7.0CA (250A rating) is the appropriate substitute. The SMCJ7.0CA is suitable only for applications with lower peak pulse current requirements.

Q: What is the difference between SMCJ7.0CA and SMCJ7.0CA-TP?

A: Both parts are electrically identical with 7V reverse standoff voltage, 7.78V breakdown voltage, and 12V clamping voltage. The primary difference is packaging: SMCJ7.0CA-TP is supplied in tape and reel format suitable for automated assembly, while SMCJ7.0CA packaging is not specified. Additionally, SMCJ7.0CA-TP has an extended operating temperature range to 175°C compared to 150°C for the standard variant.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. The SMLJ7.0CE3/TR13 and all three identified substitutes (SMCJ7.0CA, SMCJ7.0CA-TP, and SMDJ7.0CA) are RoHS3 compliant, ensuring regulatory conformance for applications subject to RoHS requirements.

Q: Can I use SMDJ7.0CA if my application only requires 300W peak pulse power?

A: Yes. The SMDJ7.0CA is rated for 3000W peak pulse power, which exceeds the 300W requirement. Higher power ratings do not create compatibility issues; the device will operate within specification in applications requiring lower power dissipation. The SMDJ7.0CA is a valid substitute for any application within the 7V Zener category.

Q: What is the moisture sensitivity level (MSL) for SMDJ7.0CA?

A: The moisture sensitivity level for SMDJ7.0CA is not specified in the provided data. The SMLJ7.0CE3/TR13, SMCJ7.0CA, and SMCJ7.0CA-TP all have MSL 1 (Unlimited) rating. If MSL 1 is a requirement for your application, confirm SMDJ7.0CA specifications with the manufacturer or select from the other three substitutes.

Q: Do all substitute parts use the same DO-214AB package?

A: Yes. The SMLJ7.0CE3/TR13 and all three substitutes use the DO-214AB (SMC) surface-mount package, ensuring mechanical and footprint compatibility on printed circuit boards.
