SM6T200CA-M3/52 Equivalent & Substitute Parts

Part Overview

The SM6T200CA-M3/52 is a bidirectional Zener transient voltage suppressor (TVS) diode manufactured by Vishay General Semiconductor - Diodes Division. This surface mount component operates in the DO-214AA (SMBJ) package and provides transient overvoltage protection for general-purpose applications. The part is active in production status with ROHS3 compliance and unlimited moisture sensitivity rating. 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 SM6T200CA-M3/52 is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff (Typ): 171V
• Voltage - Breakdown (Min): 190V
• Voltage - Clamping (Max) @ Ipp: 274V
• Current - Peak Pulse (10/1000µs): 2.2A
• Power - Peak Pulse: 600W
• Package / Case: DO-214AA, SMB (surface mount)
• Mounting Type: Surface Mount
• Type: Zener
• Bidirectional Channels: 1

All identified substitute parts maintain these electrical specifications and mechanical compatibility. Variations in operating temperature range, manufacturer, packaging format (Tape & Reel vs. Cut Tape), and series designation do not affect functional substitutability when these core parameters are matched.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain active production status and comply with applicable environmental regulations. Selection among equivalent options should be based on:

Manufacturer Continuity: The P6SMB200CA-E3/52 (Vishay) maintains the same manufacturer as the primary part, ensuring consistent design lineage and quality control protocols within the TransZorb® product family.

Temperature Operating Range: The SMBJP6KE200CA-TP (Micro Commercial Co) extends the upper operating temperature to 175°C compared to 150°C for the primary part and P6SMB200CA-E3/52, providing additional thermal margin in high-temperature environments. The P6SMB200CA (Eaton) operates to 150°C with a lower minimum temperature of -55°C.

Packaging and Supply Format: The P6SMB200CA (Eaton) is available in Cut Tape and Digi-Reel® format, offering flexibility for lower-volume or mixed-component procurement. The Vishay and Micro Commercial Co options are supplied in standard Tape & Reel format.

Compliance Certifications: All parts maintain MSL 1 (Unlimited) rating and RoHS compliance. ROHS3 compliance is confirmed for Vishay and Micro Commercial Co parts; Eaton part carries standard RoHS compliance.

Frequently Asked Questions (FAQ)

Q: Can the P6SMB200CA-E3/52 be used as a direct replacement for the SM6T200CA-M3/52?

A: Yes. Both parts share identical electrical specifications (171V standoff, 190V breakdown minimum, 274V clamping maximum, 2.2A peak pulse current, 600W peak power) and the same DO-214AA SMB package. Both are manufactured by Vishay and maintain ROHS3 compliance. The primary difference is the series designation (P6SMB vs. SM6T) and packaging format (both Tape & Reel).

Q: What is the difference between the Eaton P6SMB200CA and the Vishay P6SMB200CA-E3/52?

A: Both parts are electrically equivalent with identical voltage and current ratings. The Eaton part operates over -55°C to 150°C (vs. -65°C to 150°C for Vishay), carries standard RoHS compliance (vs. ROHS3), and is available in Cut Tape and Digi-Reel® packaging format. The Vishay part is available in Tape & Reel format.

Q: Does the Micro Commercial Co SMBJP6KE200CA-TP offer any performance advantages?

A: The SMBJP6KE200CA-TP maintains all electrical equivalence to the primary part but extends the maximum operating temperature to 175°C (vs. 150°C). This provides additional thermal headroom in applications subject to elevated ambient or junction temperatures. All other electrical and mechanical parameters are identical.

Q: Are there any package compatibility concerns when substituting these parts?

A: No. All substitute parts use the DO-214AA SMB surface mount package with identical footprint and land pattern. PCB layout and reflow soldering profiles remain unchanged across all listed alternatives.

Q: What is the significance of the MSL 1 (Unlimited) rating?

A: MSL 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. All listed parts carry this rating, eliminating moisture sensitivity as a selection criterion.

Q: Can these parts be used interchangeably in production?

A: Yes, provided the application requirements fall within the operating temperature and compliance specifications of the selected substitute. All parts are active in production, carry appropriate certifications, and maintain functional equivalence across the critical electrical parameters that determine TVS diode performance.
