P6SMB160AT3 Equivalent & Substitute Parts

Part Overview

The P6SMB160AT3 is a unidirectional Transient Voltage Suppressor (TVS) diode manufactured by onsemi, rated for 600W peak pulse power at 160V. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. The part is housed in an SMB (DO-214AA) surface mount package and is RoHS non-compliant with unlimited moisture sensitivity rating.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the P6SMB160AT3 are qualified based on the following electrical and mechanical parameters:

Substitution Criteria:

• Package type: SMB (DO-214AA) surface mount
• Power rating: 600W peak pulse power
• Unidirectional zener TVS diode configuration
• Voltage class: 130V–160V reverse standoff range
• Clamping voltage: 200V–270V maximum at peak pulse current
• Peak pulse current capability: 2.8A–15A (10/1000µs or 8/20µs)
• Operating temperature range: -50°C to -55°C minimum, 150°C maximum
• Mounting compatibility: Surface mount, same footprint

All three substitute parts meet these core electrical and mechanical requirements, enabling direct replacement in circuit designs originally specified for the P6SMB160AT3.

Parameter Comparison

Engineering Selection Recommendations

P6SMB160A (Eaton - Electronics Division): This part provides the closest electrical match to the P6SMB160AT3 with a 136V reverse standoff voltage and 219V clamping voltage. It is RoHS Compliant and currently in active production status with 47,300 units in stock. Recommended for applications requiring compliance with modern environmental standards.

SM6T150A (STMicroelectronics): This part operates at a lower reverse standoff voltage (128V) but offers higher peak pulse current capability (15A at 8/20µs) and a higher clamping voltage (265V). It is ROHS3 Compliant and actively produced. Suitable for applications requiring enhanced transient suppression performance and regulatory compliance.

SMBJ130A (MDD): This part provides a 130V reverse standoff voltage with 209V clamping voltage and 2.9A peak pulse current. It is ROHS3 Compliant and actively produced with 55,100 units in stock. The operating temperature minimum is -50°C, which is 5°C higher than the main part. Appropriate for general-purpose applications with modern compliance requirements.

All three substitutes are actively produced, RoHS-compliant alternatives to the obsolete P6SMB160AT3, eliminating supply chain risk and meeting current environmental regulations.

Frequently Asked Questions (FAQ)

Q: Can P6SMB160A directly replace P6SMB160AT3 in existing designs? A: Yes. Both parts share identical SMB package geometry, 600W power rating, and compatible voltage/current characteristics. The P6SMB160A is the closest electrical equivalent with active production status.

Q: What is the primary difference between SM6T150A and the other substitutes? A: SM6T150A offers significantly higher peak pulse current (15A at 8/20µs) compared to P6SMB160A and SMBJ130A (2.8A–2.9A at 10/1000µs). This makes it suitable for applications requiring enhanced transient suppression capability, though at a lower reverse standoff voltage (128V).

Q: Are all substitutes RoHS compliant? A: P6SMB160A is RoHS Compliant. SM6T150A and SMBJ130A are both ROHS3 Compliant. The original P6SMB160AT3 is RoHS non-compliant. For new designs, all three substitutes meet current environmental standards.

Q: Does operating temperature range affect part selection? A: SMBJ130A has a minimum operating temperature of -50°C, compared to -55°C for the other parts. For applications operating below -50°C, P6SMB160A or SM6T150A are required.

Q: Which substitute has the highest inventory availability? A: SMBJ130A has the highest stock level at 55,100 units, followed by P6SMB160A at 47,300 units, and SM6T150A at 36,450 units.

Q: Can I use these parts interchangeably in the same circuit? A: Yes, within the constraints of your circuit's voltage and current requirements. Verify that the reverse standoff voltage and clamping voltage of the selected substitute are appropriate for your specific transient protection application.
