P6SMB180A-M3/52 Equivalent & Substitute Parts

Part Overview

The P6SMB180A-M3/52 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 series, designed for surface mount applications in the DO-214AA (SMB) package. The device is Active status and RoHS3 compliant, with unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained across the specified parameter ranges.

Substitute Part Grouping Explanation

Substitute parts for the P6SMB180A-M3/52 are identified based on strict electrical and mechanical parameter equivalence. The substitution criteria are:

• Voltage - Reverse Standoff (Typ): 154V
• Voltage - Breakdown (Min): 171V
• Voltage - Clamping (Max) @ Ipp: 246V
• Current - Peak Pulse (10/1000µs): ≥ 2.4A
• Power - Peak Pulse: 600W
• Package / Case: DO-214AA or SMB
• Mounting Type: Surface Mount
• Unidirectional Channels: 1
• Type: Zener

The P6SMB180A manufactured by Eaton - Electronics Division meets these criteria with a peak pulse current of 2.5A, which exceeds the minimum requirement of 2.4A. Both parts maintain identical voltage specifications and power ratings, with compatible surface mount packaging.

Parameter Comparison

Engineering Selection Recommendations

The P6SMB180A manufactured by Eaton - Electronics Division is a direct substitute for the P6SMB180A-M3/52. Both components are Active status products with full RoHS compliance and identical regulatory classifications (ECCN EAR99, HTSUS 8541.10.0080).

The Eaton variant provides equivalent electrical performance with a peak pulse current specification of 2.5A, which exceeds the Vishay part's 2.4A rating while maintaining all voltage parameters. Both devices support the same operating temperature maximum of 150°C and share identical moisture sensitivity ratings.

The primary difference is the lower operating temperature minimum for the Eaton part (-55°C versus -65°C). Selection between these parts should be based on application temperature requirements and packaging preference (Tape & Box for Vishay versus Tape & Reel for Eaton).

Frequently Asked Questions (FAQ)

Q: Can the Eaton P6SMB180A replace the Vishay P6SMB180A-M3/52 in all applications?

A: Yes, provided the application does not require operation below -55°C. The Eaton part meets or exceeds all electrical specifications and maintains identical package compatibility.

Q: What is the significance of the higher peak pulse current (2.5A vs 2.4A) in the Eaton part?

A: The higher current rating provides additional margin for transient suppression. This does not affect compatibility; the part remains suitable for circuits designed for the 2.4A specification.

Q: Are there packaging differences between these parts?

A: Both parts use the DO-214AA (SMB) surface mount package. The primary packaging difference is the supply format: Vishay offers Tape & Box (TB) while Eaton supplies Tape & Reel (TR). The physical component dimensions and PCB footprint are identical.

Q: Do both parts meet the same compliance standards?

A: Both parts are RoHS compliant with EAR99 export classification and identical HTSUS codes. The Vishay part carries ROHS3 certification while the Eaton part carries standard RoHS certification. Both are MSL 1 rated with unlimited moisture sensitivity.

Q: What should determine the choice between these substitute parts?

A: Selection criteria are: (1) minimum operating temperature requirement—use Vishay if below -55°C operation is needed; (2) packaging format preference—Tape & Box versus Tape & Reel; (3) inventory availability and lead time; (4) application-specific compliance documentation requirements.
