P6SMB150A-M3/52 Equivalent & Substitute Parts

Part Overview

The P6SMB150A-M3/52 is a unidirectional transient voltage suppressor (TVS) diode manufactured by Vishay General Semiconductor - Diodes Division. This surface mount component operates in the 128V reverse standoff voltage class and provides 600W peak pulse power dissipation in a compact DO-214AA (SMB) package. The part is Active status and ROHS3 compliant, making it suitable for general-purpose transient protection applications. Equivalent and substitute parts are identified based on matching electrical performance parameters and mechanical compatibility within the DO-214AA package form factor.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the P6SMB150A-M3/52 are classified based on electrical parameter equivalence and mechanical compatibility. The primary substitution criteria are:

• Voltage - Reverse Standoff (Typ): 128V
• Voltage - Clamping (Max) @ Ipp: 207V
• Current - Peak Pulse (10/1000µs): 2.9A
• Power - Peak Pulse: 600W
• Package / Case: DO-214AA, SMB
• Mounting Type: Surface Mount
• Product Status: Active
• RoHS Compliance: ROHS3 Compliant

Parts meeting all these criteria are direct electrical and mechanical equivalents. Parts with identical standoff and clamping voltages but different peak pulse current or clamping voltage characteristics are listed as manufacturer-recommended alternatives where performance parameters remain within acceptable application ranges.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (Identical Electrical and Mechanical Parameters):

P6SMB150A-E3/52 (Vishay) and SZP6SMB150AT3G (Littelfuse) are direct functional equivalents to the P6SMB150A-M3/52. Both maintain identical voltage ratings, peak pulse current, and power dissipation specifications. The primary difference is packaging format: P6SMB150A-E3/52 is supplied in Tape & Reel (TR) format, while the main part is Tape & Box (TB). SZP6SMB150AT3G includes AEC-Q101 automotive qualification and operates across the full -65°C to 150°C temperature range.

Cross-Manufacturer Equivalent:

P6SMB150A (Good-Ark Semiconductor) provides electrical equivalence with identical voltage and current ratings. The operating temperature range is -55°C to 150°C, which is narrower at the lower end compared to the main part. This part is suitable for applications where the lower temperature limit is acceptable.

Manufacturer-Recommended Alternative:

SM6T150A (STMicroelectronics) shares the same reverse standoff voltage (128V) and package form factor but exhibits different clamping characteristics. The clamping voltage is 265V (versus 207V) and peak pulse current is 15A (8/20µs) versus 2.9A (10/1000µs). This part is recommended where higher transient current handling and elevated clamping voltage are acceptable or beneficial for the application.

All substitute parts maintain ROHS3 compliance and surface mount DO-214AA (SMB) package compatibility.

Frequently Asked Questions (FAQ)

Q: Can P6SMB150A-E3/52 replace P6SMB150A-M3/52 directly?

A: Yes. Both parts are manufactured by Vishay and share identical electrical specifications: 128V reverse standoff, 207V clamping voltage, 2.9A peak pulse current, and 600W power dissipation. The difference is packaging format (Tape & Reel versus Tape & Box). Electrical performance and PCB footprint compatibility are identical.

Q: What is the difference between P6SMB150A from Good-Ark Semiconductor and the Vishay version?

A: The Good-Ark P6SMB150A maintains all critical electrical parameters (128V standoff, 207V clamping, 2.9A peak pulse, 600W power). The operating temperature range is -55°C to 150°C versus -65°C to 150°C for the Vishay part. Selection depends on whether the lower temperature limit of -65°C is required for your application.

Q: Is SM6T150A a suitable substitute?

A: SM6T150A is a manufacturer-recommended alternative with the same 128V reverse standoff voltage and DO-214AA package. However, it exhibits different transient response characteristics: 265V clamping voltage and 15A peak pulse current (8/20µs pulse definition) versus 207V and 2.9A (10/1000µs) for the P6SMB150A-M3/52. Use SM6T150A only when higher clamping voltage and peak current capability are acceptable or required by the circuit design.

Q: Does SZP6SMB150AT3G include automotive qualification?

A: Yes. SZP6SMB150AT3G is AEC-Q101 qualified and rated for automotive applications. It provides identical electrical performance to the P6SMB150A-M3/52 (128V standoff, 207V clamping, 2.9A peak pulse) and operates across the full -65°C to 150°C temperature range.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (P6SMB150A-E3/52, P6SMB150A, SM6T150A, and SZP6SMB150AT3G) are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: What packaging formats are available for these parts?

A: P6SMB150A-M3/52 is supplied in Tape & Box (TB). P6SMB150A-E3/52 is Tape & Reel (TR). P6SMB150A (Good-Ark) is available in Cut Tape (CT) & Digi-Reel. SM6T150A is Cut Tape (CT) & Digi-Reel. SZP6SMB150AT3G is Tape & Reel (TR). Verify packaging requirements for your procurement and assembly process.
