SMAJ200A-TP Transient Voltage Suppressor Equivalent & Substitute Parts

Part Overview

The SMAJ200A-TP is a unidirectional transient voltage suppressor (TVS) diode manufactured by Micro Commercial Co, designed for general-purpose overvoltage protection in surface-mount applications. This component operates with a 200V reverse standoff voltage and provides 324V maximum clamping voltage at peak pulse current. The part is currently active in production and ROHS3 compliant. Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and supply chain continuity when the primary part becomes unavailable or when alternative manufacturers' stock levels are more favorable.

Substitute Part Grouping Explanation

Substitute parts for the SMAJ200A-TP are qualified based on electrical parameter equivalence and mechanical compatibility. The substitution criteria are:

• Voltage - Reverse Standoff (Typ): 200V
• Voltage - Breakdown (Min): 224V
• Voltage - Clamping (Max) @ Ipp: 324V
• Current - Peak Pulse (10/1000µs): 1.2A
• Power - Peak Pulse: 400W
• Type: Zener, Unidirectional
• Package / Case: DO-214AC, SMA
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

All identified substitute parts meet these electrical and mechanical parameters, ensuring functional equivalence in circuit applications. Differences in operating temperature range and manufacturer do not affect substitution eligibility for general-purpose applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts—SMAJ200A-TP (Micro Commercial Co), SMAJ200A (Good-Ark Semiconductor), and SMAJ200A-13-F (Diodes Incorporated)—are active products with ROHS3 compliance and REACH unaffected status. Selection among these equivalents should be based on:

• Availability and inventory levels at the time of procurement
• Supplier lead times and logistics requirements
• Compliance certifications applicable to the end application
• Manufacturer qualification requirements within your organization

The SMAJ200A-TP offers an extended operating temperature range to 175°C (TA), while both substitute parts operate to 150°C (TJ). This difference is not a limiting factor for general-purpose applications operating within standard industrial temperature ranges.

Frequently Asked Questions (FAQ)

Q: Can SMAJ200A (Good-Ark Semiconductor) be used as a direct replacement for SMAJ200A-TP?

A: Yes. Both parts share identical electrical parameters: 200V reverse standoff voltage, 224V minimum breakdown voltage, 324V maximum clamping voltage, 1.2A peak pulse current, and 400W peak pulse power. Both are packaged in DO-214AC (SMA) surface-mount format and are ROHS3 compliant with MSL 1 rating.

Q: What is the difference between SMAJ200A-13-F and SMAJ200A-TP?

A: The electrical and mechanical specifications are equivalent. The primary differences are manufacturer (Diodes Incorporated vs. Micro Commercial Co) and operating temperature range (150°C vs. 175°C maximum). Both are suitable for general-purpose TVS applications.

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

A: No. All three parts use the DO-214AC (SMA) package with surface-mount configuration. PCB footprints and reflow soldering profiles are compatible across all substitutes.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. All parts are ROHS3 compliant, REACH unaffected, classified as EAR99, and share the same HTSUS code (8541.10.0080). Moisture sensitivity level is 1 (Unlimited) for all parts.

Q: Which part should I select if I need the highest operating temperature rating?

A: The SMAJ200A-TP offers the highest operating temperature range at -55°C to 175°C (TA). The substitute parts from Good-Ark Semiconductor and Diodes Incorporated are rated to -55°C to 150°C (TJ).
