Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the P6SMB56A-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
• Mounting Type: Surface Mount
• Package / Case: DO-214AA, SMB
• Type: Zener, Unidirectional

Substitute parts must maintain identical voltage specifications and package form factor to ensure direct circuit compatibility. Peak pulse current and power ratings may vary within acceptable operational margins for the application. Packaging format (Tape & Box versus Tape & Reel) does not affect electrical compatibility but impacts procurement and handling procedures.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain identical voltage specifications (47.8V reverse standoff, 53.2V breakdown minimum, 77V clamping maximum) and package form factor (DO-214AA, SMB surface mount), ensuring direct electrical and mechanical compatibility with the P6SMB56A-M3/5B.

P6SMB56A-E3/52 (Vishay) is a direct equivalent differing only in packaging format (Tape & Reel versus Tape & Box). This part maintains identical electrical specifications and operating temperature range (-65°C ~ 150°C). Selection is appropriate for high-volume procurement requiring reel packaging.

SMBJP6KE56A-TP (Micro Commercial Co) provides equivalent voltage performance with marginally higher peak pulse current (7.9A versus 7.8A) and extended operating temperature range (-55°C ~ 175°C). This part is suitable for applications requiring enhanced thermal performance.

1KSMB56A (Taiwan Semiconductor Corporation) maintains identical voltage specifications with significantly higher peak pulse current (13A) and power rating (1000W versus 600W). This part is suitable for applications requiring enhanced transient energy absorption capacity while maintaining the same voltage clamping characteristics.

P6SMB56A (Eaton - Electronics Division) provides equivalent voltage performance with marginally higher peak pulse current (7.9A) and extended operating temperature range (-55°C ~ 150°C). RoHS compliance is confirmed. This part is suitable for telecom applications.

All substitute parts are Active product status with RoHS compliance and MSL 1 (Unlimited) moisture sensitivity rating, supporting standard manufacturing and storage procedures.

Frequently Asked Questions (FAQ)

Q: Can P6SMB56A-E3/5B be used as a direct replacement for P6SMB56A-M3/5B?

A: Yes. Both parts are manufactured by Vishay with identical electrical specifications (47.8V reverse standoff, 77V clamping voltage, 7.8A peak pulse current) and package form factor (DO-214AA, SMB). The difference is packaging format: M3/5B uses Tape & Box while E3/52 uses Tape & Reel. Electrical and mechanical compatibility is maintained.

Q: What is the difference between the Vishay P6SMB56A and the Taiwan Semiconductor 1KSMB56A?

A: Both parts maintain identical voltage specifications (47.8V reverse standoff, 77V clamping). The 1KSMB56A provides higher peak pulse current (13A versus 7.8A) and power rating (1000W versus 600W). Selection depends on transient energy absorption requirements. Voltage clamping performance is equivalent.

Q: Are all substitute parts compatible with the same PCB footprint?

A: Yes. All substitute parts use the DO-214AA (SMB) package form factor with identical mechanical dimensions and pin configuration. Direct PCB footprint compatibility is maintained across all listed substitutes.

Q: What is the impact of operating temperature range differences?

A: The main part (P6SMB56A-M3/5B) operates from -65°C to 150°C. SMBJP6KE56A-TP and 1KSMB56A extend the lower operating limit to -55°C and upper limit to 175°C. Selection should be based on application temperature requirements. All parts maintain specified voltage performance within their respective operating ranges.

Q: Can these parts be used interchangeably in production?

A: Yes, provided the application requirements fall within the electrical specifications of the selected substitute. Voltage specifications are identical across all parts. Peak pulse current and power ratings vary; selection should match or exceed application transient energy levels. Packaging format differences (Tape & Box versus Tape & Reel) do not affect electrical interchangeability but impact procurement and assembly procedures.
