SMCJ36C Transient Voltage Suppressor - Equivalent & Substitute Parts

Part Overview

The SMCJ36C is a bidirectional transient voltage suppressor (TVS) diode manufactured by Taiwan Semiconductor Corporation. This surface mount component operates at 36V reverse standoff voltage with 1500W peak pulse power rating and is designed for general-purpose transient protection applications. The part is active in production status and complies with RoHS3 and REACH regulations.

Substitute parts are identified based on matching electrical specifications and mechanical compatibility within the TVS diode category. Alternative sources become necessary when primary inventory is unavailable or when supply chain requirements mandate qualified alternatives.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SMCJ36C are qualified based on the following critical parameters:

Electrical Compatibility Criteria:

• Voltage - Reverse Standoff (Typ): 36V
• Voltage - Breakdown (Min): 40V
• Power - Peak Pulse: 1500W
• Operating Temperature Range: -55°C to 150°C
• Bidirectional Channels: 1
• Type: Zener

Mechanical Compatibility Criteria:

• Mounting Type: Surface Mount
• Package / Case: DO-214AB, SMC

Regulatory Compliance:

• RoHS3 Compliant
• REACH Unaffected

The SMCJ36CA from EVVO Semi qualifies as a substitute based on matching reverse standoff voltage, breakdown voltage, peak pulse power rating, operating temperature range, bidirectional channel configuration, zener type classification, surface mount mounting type, and SMC package format. Both parts maintain identical regulatory compliance status.

Parameter Comparison

Engineering Selection Recommendations

Both the SMCJ36C and SMCJ36CA are active production components with RoHS3 compliance and REACH unaffected status. Selection between these parts is based on availability and packaging format requirements.

The SMCJ36C is supplied in Tape & Reel (TR) packaging with 1600 pieces in current inventory. The SMCJ36CA is supplied in Cut Tape (CT) and Digi-Reel® packaging with 32100 pieces in current inventory and includes Moisture Sensitivity Level (MSL) 1 rating.

Both parts maintain identical electrical performance within the specified parameter ranges for general-purpose transient voltage suppression applications. The SMCJ36CA exhibits lower clamping voltage (58.1V versus 64.3V) and higher peak pulse current (25.9A versus 24A), both of which represent improved performance characteristics within the 1500W power rating constraint.

Frequently Asked Questions (FAQ)

Q: What determines if a TVS diode can substitute for the SMCJ36C?

A: Substitute TVS diodes must match the following parameters: 36V reverse standoff voltage, 40V minimum breakdown voltage, 1500W peak pulse power rating, -55°C to 150°C operating temperature range, single bidirectional channel configuration, zener type classification, surface mount mounting type, and DO-214AB SMC package format.

Q: Are the SMCJ36C and SMCJ36CA electrically interchangeable?

A: Both parts meet the core electrical specifications for 36V transient protection. The SMCJ36CA exhibits lower clamping voltage and higher peak pulse current within the same 1500W power envelope, representing equivalent or improved performance for the specified application category.

Q: What is the difference in packaging between these parts?

A: The SMCJ36C is supplied in Tape & Reel (TR) format. The SMCJ36CA is supplied in Cut Tape (CT) and Digi-Reel® format. Both use the same DO-214AB SMC surface mount package for PCB assembly.

Q: Do both parts meet the same regulatory requirements?

A: Both the SMCJ36C and SMCJ36CA are RoHS3 compliant and REACH unaffected. Both carry EAR99 export classification and identical HTSUS commodity codes.

Q: What is the Moisture Sensitivity Level (MSL) for these parts?

A: The SMCJ36C does not specify an MSL rating in the provided data. The SMCJ36CA is rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage and handling.
