Parameter Comparison

Engineering Selection Recommendations

P6SMB47A-E3/52 (Vishay, Tape & Reel) Direct equivalent with identical electrical specifications and operating temperature range. Same manufacturer as the primary part. Suitable for high-volume procurement where Tape & Reel packaging is preferred. ROHS3 compliant.

SMBJP6KE47A-TP (Micro Commercial Co, Tape & Reel) Meets all critical voltage and package specifications. Offers extended upper operating temperature to 175°C compared to the primary part's 150°C maximum. Peak pulse current specification is marginally higher at 9.4A. ROHS3 compliant. Appropriate for applications requiring enhanced thermal performance.

1KSMB47A (Taiwan Semiconductor Corporation, Tape & Reel) Meets all critical voltage and package specifications. Provides enhanced performance with peak pulse current of 15.4A and peak pulse power of 1000W, compared to the primary part's 9.3A and 600W. Extended operating temperature range to 175°C. ROHS3 compliant. Suitable for applications requiring higher transient current handling capability.

P6SMB47A (Eaton - Electronics Division, Tape & Reel) Meets all critical voltage and package specifications. Peak pulse current specification is 9.4A. Operating temperature range extends to -55°C minimum. RoHS compliant. Appropriate for general-purpose applications with Telecom classification.

All substitute parts maintain Active product status and full compliance with applicable environmental and trade regulations (REACH Unaffected, ECCN EAR99, HTSUS 8541.10.0080).

Frequently Asked Questions (FAQ)

Q: Can P6SMB47A-E3/52 be used as a direct replacement for P6SMB47A-M3/5B? A: Yes. Both parts are manufactured by Vishay and share identical electrical specifications: 40.2V reverse standoff, 44.7V breakdown minimum, and 64.8V clamping voltage. The primary difference is packaging format (Tape & Reel versus Tape & Box). Both are ROHS3 compliant and Active status.

Q: What is the difference between the 1KSMB47A and the original P6SMB47A-M3/5B? A: The 1KSMB47A maintains identical voltage specifications but provides enhanced performance with 15.4A peak pulse current (versus 9.3A) and 1000W peak pulse power (versus 600W). Operating temperature range extends to 175°C. This part is suitable for applications requiring higher transient current handling.

Q: Are all substitute parts available in the same DO-214AA SMB package? A: Yes. All identified substitutes use the DO-214AA (SMB) surface mount package, ensuring mechanical and footprint compatibility with the original design.

Q: What is the significance of the operating temperature range differences? A: The primary part operates from -65°C to 150°C. Substitute parts from Micro Commercial Co and Taiwan Semiconductor extend the upper limit to 175°C, providing enhanced thermal margin in high-temperature applications. The Eaton part maintains the same upper limit of 150°C.

Q: Can I mix packaging formats (Tape & Box and Tape & Reel) in production? A: Packaging format selection depends on manufacturing and assembly requirements. Tape & Reel is standard for automated pick-and-place assembly, while Tape & Box may be preferred for manual assembly or lower-volume applications. Electrical and mechanical specifications are identical regardless of packaging format.

Q: Are all substitute parts RoHS compliant? A: Yes. All identified substitutes are either ROHS3 compliant or RoHS compliant, meeting environmental regulatory requirements.
