P6SMB100CA Equivalent & Substitute Parts

Part Overview

The P6SMB100CA is a transient voltage suppressor (TVS) diode manufactured by Bourns Inc., designed for general-purpose overvoltage protection applications. This bidirectional zener diode operates with a reverse standoff voltage of 85.5V and provides clamping at 137V maximum, with a peak pulse power rating of 600W. The component is surface-mounted in a DO-214AA (SMB) package and maintains active product status with full RoHS3 compliance. Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and supply chain continuity for applications requiring identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P6SMB100CA is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff (Typ): 85.5V
• Voltage - Breakdown (Min): 95V
• Voltage - Clamping (Max) @ Ipp: 137V
• Power - Peak Pulse: 600W
• Package / Case: DO-214AA (SMB)
• Mounting Type: Surface Mount
• Bidirectional Channels: 1
• Operating Temperature Range: -55°C to 150°C

The P6SMB100CA manufactured by Good-Ark Semiconductor meets all specified electrical parameters within acceptable tolerances and maintains identical mechanical and thermal characteristics. Peak pulse current variance (4.4A vs. 4.5A) remains within the functional envelope for general-purpose TVS applications at the specified voltage and power ratings.

Parameter Comparison

Engineering Selection Recommendations

Both the Bourns Inc. P6SMB100CA and Good-Ark Semiconductor P6SMB100CA are active products with full RoHS3 compliance and MSL Level 1 rating, indicating no moisture sensitivity restrictions during storage and handling. Selection between these parts may be based on:

• Procurement availability and lead time
• Supply chain logistics and regional sourcing requirements
• Inventory management and stock rotation policies
• Cost considerations within equivalent specification parameters

No technical performance differentiation exists between these components for general-purpose TVS applications within the specified electrical and thermal operating envelope.

Frequently Asked Questions (FAQ)

Q: Can the Good-Ark Semiconductor P6SMB100CA directly replace the Bourns Inc. P6SMB100CA in existing designs?

A: Yes. Both components share identical voltage ratings (85.5V standoff, 95V breakdown minimum, 137V clamping maximum), power dissipation (600W peak pulse), package configuration (DO-214AA SMB), and operating temperature range (-55°C to 150°C). The 0.1A difference in peak pulse current (4.4A vs. 4.5A) does not affect functional compatibility for general-purpose applications.

Q: Are there any compliance or certification differences between these parts?

A: Both parts are RoHS3 compliant and carry MSL Level 1 rating. The Bourns part is REACH Affected; the Good-Ark part is REACH Unaffected. Verify REACH compliance requirements for your specific application and end-use region before selection.

Q: What is the significance of the DO-214AA (SMB) package designation?

A: DO-214AA is the industry-standard surface-mount package for TVS diodes in this power class. SMB is the common abbreviation. Both parts use this identical package, ensuring mechanical and thermal compatibility with existing PCB layouts and reflow soldering processes.

Q: Are these parts suitable for power line protection applications?

A: No. Both components are designated for general-purpose applications only and are not rated for direct power line protection. Verify application requirements against the specified electrical ratings before deployment.

Q: What inventory status should I expect?

A: Both parts show 1450 pieces in new original stock. Verify current availability with your supplier, as inventory levels change continuously.
