P6SMB130A-E3/5B Equivalent & Substitute Parts

Part Overview

The P6SMB130A-E3/5B is a unidirectional Transient Voltage Suppressor (TVS) diode manufactured by Vishay General Semiconductor - Diodes Division. This component operates as a Zener-type TVS device in the P6SMB TransZorb® series, designed for surface mount applications in the DO-214AA (SMB) package. The part is Active status and RoHS3 compliant. Equivalent and substitute parts are identified based on matching electrical performance parameters and mechanical compatibility within the TVS diode category.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the P6SMB130A-E3/5B are identified based on the following criteria:

Direct Electrical Parameter Match: Substitute parts must maintain the same reverse standoff voltage (111V typical), breakdown voltage minimum (124V), and clamping voltage maximum (179V) to ensure functional equivalence in circuit protection applications.

Package Compatibility: All substitute parts must use the DO-214AA (SMB) surface mount package to ensure mechanical and thermal compatibility with existing PCB layouts.

Device Type: Substitute parts must be unidirectional Zener-type TVS diodes with a single channel configuration.

Power Rating: Peak pulse power rating of 600W is maintained across all substitute options.

Compliance Status: Substitute parts must maintain Active product status and RoHS compliance to meet current procurement and regulatory requirements.

Parameter Comparison

Engineering Selection Recommendations

P6SMB130A (Eaton - Electronics Division): This part is a direct electrical equivalent to the P6SMB130A-E3/5B, maintaining identical voltage parameters (111V standoff, 124V breakdown, 179V clamping) and current ratings (3.4A peak pulse). Both parts share the same package (DO-214AA, SMB) and are Active status products with RoHS compliance. The operating temperature range for the Eaton variant is -55°C to 150°C, compared to -65°C to 150°C for the Vishay part, representing a narrower low-temperature specification. Selection of this substitute is appropriate for applications where the -55°C minimum temperature meets system requirements.

SM6T150A (STMicroelectronics): This part operates at higher voltage levels (128V standoff, 143V breakdown, 265V clamping) and supports significantly higher peak pulse current (15A versus 3.4A). While the package format (DO-214AA, SMB) and power rating (600W) remain compatible, the elevated electrical parameters make this part suitable only for applications requiring enhanced overvoltage protection or higher transient current handling. This substitute is not interchangeable for direct replacement in circuits designed for the 111V/179V protection levels of the P6SMB130A-E3/5B.

Frequently Asked Questions (FAQ)

Q: Can the P6SMB130A from Eaton be used as a direct replacement for the P6SMB130A-E3/5B from Vishay?

A: Yes, the P6SMB130A from Eaton is a direct electrical equivalent. Both parts maintain identical voltage specifications (111V standoff, 124V breakdown, 179V clamping), current ratings (3.4A peak pulse), and package format (DO-214AA, SMB). The primary difference is the operating temperature range: Eaton specifies -55°C to 150°C versus Vishay's -65°C to 150°C. Substitution is valid for applications where the -55°C minimum temperature is acceptable.

Q: Is the SM6T150A from STMicroelectronics compatible with the P6SMB130A-E3/5B?

A: The SM6T150A shares the same package format (DO-214AA, SMB) but operates at significantly different electrical parameters. The SM6T150A provides higher voltage clamping (265V versus 179V) and supports higher peak pulse current (15A versus 3.4A). This part is not a direct replacement and should only be used when circuit design specifically requires these enhanced protection characteristics.

Q: What are the key parameters that determine substitution compatibility?

A: Substitution compatibility is determined by: reverse standoff voltage (111V typical), breakdown voltage minimum (124V), clamping voltage maximum (179V), peak pulse current rating (3.4A at 10/1000µs), package format (DO-214AA, SMB), and mounting type (surface mount). Deviations in these parameters indicate the substitute is not electrically equivalent.

Q: Are all substitute parts RoHS compliant?

A: Yes, all listed substitute parts maintain RoHS compliance. The P6SMB130A-E3/5B and SM6T150A are ROHS3 compliant, while the Eaton P6SMB130A is RoHS compliant. All parts have Moisture Sensitivity Level 1 (Unlimited) and are classified under ECCN EAR99.

Q: What is the difference in operating temperature ranges between the substitute options?

A: The P6SMB130A-E3/5B from Vishay operates from -65°C to 150°C (TJ), providing a wider low-temperature specification. The Eaton P6SMB130A and STMicroelectronics SM6T150A both operate from -55°C to 150°C (TJ). Selection should be based on system thermal requirements.
