Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the P6SMB7.5CA are grouped based on the following critical parameters that determine functional equivalence:

Primary Matching Criteria:

• Voltage - Reverse Standoff (Typ): 6.4V
• Voltage - Breakdown (Min): 7.13V
• Package / Case: DO-214AA, SMB
• Mounting Type: Surface Mount
• Type: Zener, Bidirectional (1 channel)
• RoHS3 Compliance
• MSL Rating: 1 (Unlimited)

Secondary Considerations:

• Voltage - Clamping (Max) @ Ipp: 11.3V to 14.5V range
• Current - Peak Pulse: 53.1A to 276A range
• Operating Temperature: -55°C to -65°C minimum, 150°C maximum
• Packaging Format: Tape & Reel (TR) or Cut Tape (CT)

Parts meeting these criteria are functionally interchangeable within the specified electrical and thermal operating windows. Variations in peak pulse current and clamping voltage reflect different manufacturer designs while maintaining the same voltage protection class.

Parameter Comparison

Engineering Selection Recommendations

P6SMB7.5CA (Taiwan Semiconductor Corporation) Primary reference part. Active product status with full RoHS3 compliance. Tape & Reel packaging supports high-volume production environments. Suitable for general-purpose transient protection applications with standard temperature range (-55°C to 150°C).

P6SMB7.5CA-E3/52 (Vishay General Semiconductor - Diodes Division) Direct electrical equivalent with identical voltage specifications and clamping characteristics. Extended minimum operating temperature (-65°C) provides additional thermal margin. Cut Tape packaging accommodates lower-volume or mixed-component assembly requirements. Active product status with RoHS3 compliance. Peak pulse current specification (53.1A) is within acceptable tolerance of primary part.

SM6T7V5CA (STMicroelectronics) Functionally equivalent within the 6.4V protection class. Elevated clamping voltage (14.5V) and significantly higher peak pulse current (276A at 8/20µs pulse) indicate enhanced transient suppression capability. Cut Tape and Digi-Reel packaging options support flexible procurement. Active product status with RoHS3 compliance. Suitable for applications requiring higher transient energy absorption.

SM6T7V5CAY (STMicroelectronics) Functionally equivalent with identical electrical specifications to SM6T7V5CA. AEC-Q101 automotive qualification and Tape & Reel packaging designate this part for automotive-grade applications. Active product status with RoHS3 compliance. Appropriate for designs requiring automotive-level component reliability and traceability.

All substitute parts maintain DO-214AA (SMB) package compatibility, surface-mount assembly capability, and unlimited moisture sensitivity rating. Selection between alternatives depends on supply availability, packaging format requirements, temperature range margins, and application-specific transient energy specifications.

Frequently Asked Questions (FAQ)

Q: Can P6SMB7.5CA-E3/52 replace P6SMB7.5CA in existing designs?

A: Yes. Both parts share identical voltage specifications (6.4V reverse standoff, 7.13V breakdown minimum, 11.3V clamping maximum) and package format (DO-214AA, SMB). Peak pulse current differs marginally (53.1A versus 55A), remaining within acceptable design tolerance. Extended temperature range of P6SMB7.5CA-E3/52 (-65°C minimum) provides additional thermal margin. Packaging format differs (Cut Tape versus Tape & Reel), which affects procurement and assembly processes but not electrical performance.

Q: What is the difference between SM6T7V5CA and SM6T7V5CAY?

A: Both parts are manufactured by STMicroelectronics with identical electrical specifications. SM6T7V5CAY includes AEC-Q101 automotive qualification and is supplied in Tape & Reel format. SM6T7V5CA is available in Cut Tape and Digi-Reel formats. Selection depends on application requirements: automotive-grade designs require SM6T7V5CAY; general-purpose applications accept either variant.

Q: Are SM6T7V5CA and SM6T7V5CAY suitable substitutes for P6SMB7.5CA?

A: Both STMicroelectronics parts are functionally compatible within the 6.4V protection class. Clamping voltage is higher (14.5V versus 11.3V) and peak pulse current is significantly higher (276A at 8/20µs versus 55A at 10/1000µs). These differences indicate enhanced transient suppression performance. Substitution is appropriate when higher transient energy absorption is acceptable or beneficial. DO-214AA (SMB) package compatibility ensures mechanical and thermal interface equivalence.

Q: What packaging formats are available for these substitute parts?

A: P6SMB7.5CA is supplied in Tape & Reel (TR) format. P6SMB7.5CA-E3/52 is supplied in Cut Tape (CT) format. SM6T7V5CA is available in both Cut Tape (CT) and Digi-Reel formats. SM6T7V5CAY is supplied in Tape & Reel (TR) format. Packaging selection affects procurement quantities, component handling, and assembly automation compatibility but does not alter electrical performance.

Q: Do all substitute parts meet RoHS3 compliance?

A: Yes. All listed substitute parts—P6SMB7.5CA, P6SMB7.5CA-E3/52, SM6T7V5CA, and SM6T7V5CAY—are RoHS3 compliant with MSL rating of 1 (Unlimited). All parts are REACH unaffected and classified under ECCN EAR99.

Q: What is the operating temperature range for each part?

A: P6SMB7.5CA, SM6T7V5CA, and SM6T7V5CAY operate from -55°C to 150°C (TJ). P6SMB7.5CA-E3/52 extends the minimum temperature to -65°C, providing additional thermal margin in cold-environment applications. Maximum operating temperature is 150°C for all parts.

Q: Can these parts be used interchangeably in automotive applications?

A: SM6T7V5CAY is specifically qualified for automotive use (AEC-Q101). Other parts are general-purpose components without automotive qualification. Automotive designs requiring component traceability and qualification documentation must use SM6T7V5CAY. General-purpose automotive applications may accept other variants based on design review and risk assessment.
