Substitute Part Grouping Explanation

Substitution for the P6SMB480A-M3/52 is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff (Typ): 408V
• Voltage - Breakdown (Min): 456V
• Voltage - Clamping (Max) @ Ipp: 658V
• Current - Peak Pulse (10/1000µs): 900–910mA range
• Power - Peak Pulse: 600W
• Package / Case: DO-214AA, SMB
• Mounting Type: Surface Mount
• Type: Zener, Unidirectional (1 channel)

The substitute part P6SMB480A from Eaton - Electronics Division meets all electrical parameter requirements within the specified tolerances. Peak pulse current variance of 10mA (900mA vs. 910mA) remains within acceptable operational margins for this device class. Both parts maintain identical voltage ratings, clamping characteristics, and power dissipation capacity.

Parameter Comparison

Engineering Selection Recommendations

The P6SMB480A from Eaton - Electronics Division is a direct electrical equivalent to the P6SMB480A-M3/52. Both components maintain Active product status and comply with RoHS regulations. The Eaton variant operates within a narrower temperature range (-55°C to 150°C versus -65°C to 150°C), which may be a consideration for applications requiring extended low-temperature performance below -55°C. Peak pulse current differs by 10mA, which remains within acceptable operational margins for TVS diode applications in this voltage class. Both parts share identical packaging, mounting configuration, and compliance certifications (RoHS, REACH Unaffected, ECCN EAR99).

Frequently Asked Questions (FAQ)

Q: Can the P6SMB480A (Eaton) replace the P6SMB480A-M3/52 (Vishay) in all applications?

A: Yes, for applications operating within the -55°C to 150°C temperature range. If your circuit requires operation below -55°C, the Vishay part's extended lower temperature limit (-65°C) is necessary.

Q: What is the significance of the 10mA difference in peak pulse current?

A: The P6SMB480A-M3/52 specifies 910mA while the Eaton P6SMB480A specifies 900mA. This 1.1% variance is within normal manufacturing tolerances for TVS diodes and does not affect functional equivalence for transient suppression applications.

Q: Are the packaging and mounting configurations identical?

A: Yes. Both parts use DO-214AA (SMB) surface mount packages. The Vishay part is supplied in Tape & Box (TB) packaging, while the Eaton part is supplied in Tape & Reel (TR) packaging. The component footprint and soldering requirements are identical.

Q: Do both parts meet the same compliance standards?

A: Both parts are RoHS compliant and REACH Unaffected. The Vishay part carries RoHS3 certification, while the Eaton part carries RoHS certification. Both meet ECCN EAR99 and HTSUS 8541.10.0080 classifications.

Q: What is the inventory availability difference?

A: The Vishay P6SMB480A-M3/52 has 996 pieces in stock, while the Eaton P6SMB480A has 25,355 pieces in stock. The Eaton variant offers significantly higher availability.
