P6SMB100CA-M3/5B Equivalent & Substitute Parts

Part Overview

The P6SMB100CA-M3/5B is a bidirectional transient voltage suppressor (TVS) diode manufactured by Vishay General Semiconductor - Diodes Division. This surface mount component operates in the 85.5V reverse standoff voltage range with a 137V maximum clamping voltage and 4.4A peak pulse current rating. The device is designed for general-purpose transient protection applications and is currently in active production status. Finding equivalent and substitute parts is necessary to ensure supply chain flexibility, optimize procurement costs, and maintain design continuity across manufacturing batches.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the P6SMB100CA-M3/5B is determined by the following critical parameters:

• Voltage - Reverse Standoff (Typ): 85.5V
• Voltage - Breakdown (Min): 95V
• Package / Case: DO-214AA, SMB
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Substitute parts must maintain identical or functionally equivalent voltage ratings, operate within the same package footprint, and meet the same environmental and compliance standards. The following parts satisfy these substitution criteria.

Parameter Comparison

Engineering Selection Recommendations

All three parts listed maintain ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1), meeting the environmental and regulatory requirements of the original P6SMB100CA-M3/5B.

The P6SMB100CA from Good-Ark Semiconductor provides direct electrical equivalence with identical voltage ratings and peak pulse current specifications. This part is suitable for direct substitution in applications where the original Vishay component is unavailable.

The SM6T100CA from STMicroelectronics maintains the same reverse standoff voltage and breakdown voltage but exhibits higher clamping voltage (178V versus 137V) and significantly higher peak pulse current capability (22.5A versus 4.4A). This part is electrically compatible for the specified voltage protection range and offers enhanced transient suppression performance. The different pulse measurement standard (8/20µs versus 10/1000µs) reflects manufacturer test methodology differences for the same device class.

All substitute parts are in active production status and available in standard surface mount packaging compatible with existing PCB designs.

Frequently Asked Questions (FAQ)

Q: Can P6SMB100CA from Good-Ark be used as a direct replacement for the Vishay P6SMB100CA-M3/5B?

A: Yes. Both parts share identical voltage ratings (85.5V reverse standoff, 95V breakdown minimum, 137V clamping maximum), peak pulse current (4.4A), power rating (600W), and package configuration (DO-214AA SMB). Both are ROHS3 compliant with MSL 1 rating.

Q: What is the difference between the SM6T100CA and the original part?

A: The SM6T100CA maintains the same reverse standoff voltage (85.5V) and breakdown voltage (95V) but specifies a higher maximum clamping voltage (178V) and higher peak pulse current (22.5A). Both operate in the same DO-214AA SMB package. The different pulse measurement standard reflects STMicroelectronics' test methodology.

Q: Are all substitute parts compatible with the same PCB footprint?

A: Yes. All listed parts use the DO-214AA SMB surface mount package, ensuring mechanical and electrical compatibility with existing PCB designs without layout modifications.

Q: Do all parts meet the same compliance standards?

A: Yes. All parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity rating, meeting the same environmental and regulatory requirements.

Q: What is the operating temperature difference between the original and substitute parts?

A: The Vishay P6SMB100CA-M3/5B operates from -65°C to 150°C, while the Good-Ark and STMicroelectronics parts operate from -55°C to 150°C. The original part provides extended low-temperature operation.
