SMCJ15C Transient Voltage Suppressor Equivalent & Substitute Parts

Part Overview

The SMCJ15C is a 1500W bidirectional transient voltage suppressor (TVS) diode manufactured by Taiwan Semiconductor Corporation. This surface mount component operates in the DO-214AB (SMC) package and provides general-purpose transient protection with a 15V reverse standoff voltage and 26.9V maximum clamping voltage. The part is active in production status and fully compliant with RoHS3 and REACH regulations. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, supply chain considerations, or design flexibility needs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SMCJ15C is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Voltage - Reverse Standoff (Typ): 15V
• Voltage - Breakdown (Min): 16.7V
• Power - Peak Pulse: 1500W
• Operating Temperature Range: -55°C to 150°C
• Mounting Type: Surface Mount
• Package / Case: DO-214AB, SMC
• Type: Zener
• Bidirectional Channels: 1

Allowable Variation Parameters:

• Voltage - Clamping (Max) @ Ipp: Variation permitted within functional limits
• Current - Peak Pulse (10/1000µs): Variation permitted within functional limits

The SMCJ15CA from EVVO Semi meets all mandatory matching parameters and is therefore qualified as a direct substitute. Both parts share identical reverse standoff voltage, breakdown voltage, peak pulse power rating, operating temperature range, and package configuration. Variations in clamping voltage (24.4V vs. 26.9V) and peak pulse current (61.5A vs. 58A) remain within acceptable functional tolerances for general-purpose transient protection applications.

Parameter Comparison

Engineering Selection Recommendations

Both the SMCJ15C and SMCJ15CA are active production components with full RoHS3 compliance and REACH unaffected status. Selection between these parts is based on availability, packaging format preference, and supply chain requirements rather than electrical performance differences.

SMCJ15C (Taiwan Semiconductor Corporation):

• Supplied in Tape & Reel (TR) packaging
• Current inventory: 1087 pcs
• Clamping voltage: 26.9V maximum

SMCJ15CA (EVVO Semi):

• Supplied in Cut Tape (CT) & Digi-Reel® packaging
• Current inventory: 84400 pcs
• Clamping voltage: 24.4V maximum
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Both parts are suitable for general-purpose transient protection applications. The SMCJ15CA offers higher peak pulse current capability (61.5A vs. 58A) and lower clamping voltage (24.4V vs. 26.9V), which may provide marginal performance advantages in specific circuit topologies. Component selection should be based on procurement lead time, packaging requirements, and inventory availability.

Frequently Asked Questions (FAQ)

Q: Can SMCJ15CA replace SMCJ15C in existing designs?

A: Yes. Both parts share identical reverse standoff voltage (15V), breakdown voltage (16.7V), peak pulse power rating (1500W), operating temperature range (-55°C to 150°C), and DO-214AB SMC package configuration. The SMCJ15CA exhibits lower clamping voltage (24.4V vs. 26.9V) and higher peak pulse current (61.5A vs. 58A), which are compatible with general-purpose transient protection applications.

Q: What are the key differences between these substitute parts?

A: The primary differences are clamping voltage specification and packaging format. SMCJ15C specifies 26.9V maximum clamping voltage and is supplied in Tape & Reel format. SMCJ15CA specifies 24.4V maximum clamping voltage and is supplied in Cut Tape & Digi-Reel® format. Both parts meet identical reverse standoff and breakdown voltage requirements.

Q: Are both parts RoHS3 compliant?

A: Yes. Both SMCJ15C and SMCJ15CA are RoHS3 compliant. The SMCJ15CA additionally specifies Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: What packaging options are available?

A: SMCJ15C is supplied in Tape & Reel (TR) packaging. SMCJ15CA is supplied in Cut Tape (CT) & Digi-Reel® packaging. Both are surface mount components in DO-214AB (SMC) package configuration suitable for automated assembly processes.

Q: Which part should be selected for new designs?

A: Selection should be based on supply chain availability and packaging requirements. Both parts are active production components with equivalent electrical performance for general-purpose transient protection. The SMCJ15CA offers significantly higher inventory availability (84400 pcs vs. 1087 pcs).
