P6SMB56CA-M3/5B Equivalent & Substitute Parts

Part Overview

The P6SMB56CA-M3/5B is a bidirectional Zener transient voltage suppressor (TVS) diode manufactured by Vishay General Semiconductor - Diodes Division. This surface mount component operates in the DO-214AA (SMB) package and is designed for general-purpose transient voltage suppression applications. The part is currently active in production with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified to provide alternative sourcing options when the primary part number is unavailable or when packaging or supplier preferences require alternatives.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the P6SMB56CA-M3/5B is determined by the following critical parameters:

• Voltage - Reverse Standoff (Typ): 47.8V
• Voltage - Breakdown (Min): 53.2V
• Voltage - Clamping (Max) @ Ipp: 77V
• Current - Peak Pulse (10/1000µs): 7.8A minimum
• Power - Peak Pulse: 600W
• Package / Case: DO-214AA, SMB
• Bidirectional Channels: 1
• Type: Zener

Substitute parts must maintain identical electrical specifications for voltage and current ratings. Packaging format (Tape & Box, Tape & Reel, or Cut Tape) represents a secondary consideration and does not affect electrical compatibility. Manufacturer variations are acceptable provided all primary electrical parameters remain within specification.

Parameter Comparison

Engineering Selection Recommendations

All three parts listed maintain active product status and full compliance with environmental regulations. The P6SMB56CA-M3/5B and P6SMB56CA-E3/52 are both manufactured by Vishay and carry ROHS3 certification. The P6SMB56CA from Eaton carries RoHS certification and meets equivalent electrical performance with a marginally higher peak pulse current rating of 7.9A versus 7.8A.

Selection between these parts should be based on packaging format availability and supplier preference. The Tape & Box format of the P6SMB56CA-M3/5B suits lower-volume applications, while the Tape & Reel format of the P6SMB56CA-E3/52 is optimized for automated assembly. The Eaton P6SMB56CA offers Cut Tape and Digi-Reel® options for flexible procurement.

The operating temperature range of the Eaton part extends to -55°C minimum versus -65°C for Vishay parts. This represents a narrower lower temperature specification and should be evaluated against application requirements.

Frequently Asked Questions (FAQ)

Q: Can P6SMB56CA-E3/52 be used as a direct replacement for P6SMB56CA-M3/5B?

A: Yes. Both parts share identical electrical specifications including voltage ratings, clamping voltage, and peak pulse current. The difference is packaging format: Tape & Box versus Tape & Reel. Electrical compatibility is complete.

Q: What is the difference between the Vishay and Eaton versions?

A: The primary difference is manufacturer. Electrical specifications are equivalent with the exception of peak pulse current (7.8A versus 7.9A) and minimum operating temperature (-65°C versus -55°C for Eaton). Both carry appropriate compliance certifications.

Q: Does packaging format affect electrical performance?

A: No. Packaging format (Tape & Box, Tape & Reel, Cut Tape) is a logistics and assembly consideration only. Electrical performance is identical across all packaging options for the same part number base.

Q: Are all three parts suitable for the same circuit application?

A: Yes, provided the application does not require operation below -55°C. All three parts maintain the same voltage suppression characteristics, clamping voltage, and power dissipation rating. The DO-214AA SMB package is identical across all variants.

Q: What certifications apply to these parts?

A: All parts carry RoHS compliance. The Vishay parts carry ROHS3 certification specifically. All parts have MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions. REACH status is unaffected for all variants.
