P6SMB110A-E3/5B Equivalent & Substitute Parts

Part Overview

The P6SMB110A-E3/5B is a unidirectional Transient Voltage Suppressor (TVS) diode manufactured by Vishay General Semiconductor - Diodes Division. This surface mount component operates in the 94V reverse standoff voltage range with a 152V maximum clamping voltage and 3.9A peak pulse current rating. The device is classified as Active product status and is RoHS3 compliant with unlimited moisture sensitivity level (MSL 1). Finding equivalent or substitute parts may be necessary due to inventory constraints, lead time requirements, or specific application demands while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the P6SMB110A-E3/5B are identified based on the following critical parameters that determine functional compatibility:

Primary Compatibility Criteria:

• Package / Case: DO-214AA (SMB) surface mount form factor
• Unidirectional Channels: 1 (single channel configuration)
• Mounting Type: Surface Mount
• Category: Transient Voltage Suppressors (TVS)
• Type: Zener diode

Electrical Parameter Ranges for Substitution:

• Voltage - Reverse Standoff: 94V nominal (allows tolerance variation across manufacturers)
• Voltage - Breakdown (Min): 105V or higher
• Voltage - Clamping (Max) @ Ipp: 152V or lower (protective threshold)
• Current - Peak Pulse: 3.9A or higher
• Power - Peak Pulse: 600W (standard for SMB package)

Substitute parts must maintain the same mechanical footprint and electrical protection characteristics while accommodating manufacturer-specific parameter variations within the defined ranges.

Parameter Comparison

Engineering Selection Recommendations

P6SMB110A (Eaton - Electronics Division): This part is the manufacturer-recommended equivalent to the P6SMB110A-E3/5B. It maintains identical electrical specifications (94V reverse standoff, 152V clamping voltage, 4A peak pulse current) and the same DO-214AA SMB package. Both parts are Active status products with RoHS compliance. The primary difference is the lower operating temperature minimum (-55°C versus -65°C for the Vishay part). Selection of this substitute is appropriate when Eaton inventory availability is preferred and the -55°C minimum temperature rating is acceptable for the application.

SM6T150A (STMicroelectronics): This part operates at a higher voltage class (128V reverse standoff, 265V clamping voltage) with significantly higher peak pulse current capability (15A). While it shares the same DO-214AA SMB package and surface mount configuration, the elevated voltage and current ratings position it for applications requiring enhanced transient protection margins. This substitute is suitable only when the higher voltage and current specifications do not create incompatibility with the circuit design. The part is Active status and RoHS3 compliant.

Frequently Asked Questions (FAQ)

Q: Can the P6SMB110A from Eaton be used as a direct replacement for the P6SMB110A-E3/5B from Vishay?

A: Yes. Both parts share identical electrical specifications (94V reverse standoff, 152V clamping voltage, 600W peak pulse power) and the same DO-214AA SMB surface mount package. The Eaton part is the manufacturer-recommended equivalent. The only specification difference is the operating temperature minimum (-55°C for Eaton versus -65°C for Vishay). Verify that your application does not require operation below -55°C before substitution.

Q: Is the SM6T150A from STMicroelectronics compatible with the P6SMB110A-E3/5B?

A: The SM6T150A shares the same DO-214AA SMB package and surface mount configuration, enabling mechanical compatibility. However, it operates at a higher voltage class (128V reverse standoff, 265V clamping) with 15A peak pulse current versus 3.9A for the original part. This substitute is compatible only if your circuit design can accommodate the higher voltage and current ratings without adverse effects. Verify circuit compatibility before implementation.

Q: What are the critical parameters for substituting TVS diodes in the SMB package?

A: Critical parameters include: (1) Package / Case format (DO-214AA SMB), (2) Unidirectional channel configuration (1 channel), (3) Voltage - Reverse Standoff rating, (4) Voltage - Clamping maximum, (5) Current - Peak Pulse rating, and (6) Power - Peak Pulse rating. All substitute parts must maintain the same mechanical footprint and electrical protection characteristics within acceptable tolerance ranges for your specific application.

Q: Are all listed substitute parts RoHS compliant?

A: Yes. The P6SMB110A-E3/5B (RoHS3 Compliant), P6SMB110A from Eaton (RoHS Compliant), and SM6T150A (RoHS3 Compliant) all meet RoHS compliance requirements. All parts carry unlimited moisture sensitivity level (MSL 1) ratings.

Q: What is the difference between the 10/1000µs and 8/20µs pulse specifications?

A: These specifications define the test pulse waveform used to measure peak pulse current. The P6SMB110A-E3/5B and P6SMB110A use 10/1000µs waveforms, while the SM6T150A uses 8/20µs waveforms. These represent different industry standard test conditions and do not indicate incompatibility; they reflect manufacturer testing methodology for the respective product lines.
