Key Parameters

Substitute Part Grouping Explanation

Substitution for the P6KE7.5 is determined by the following critical parameters:

• Voltage Rating: Reverse standoff voltage of 6.4V and breakdown voltage minimum of 7.13V
• Power Dissipation: 600W peak pulse power rating
• Package Configuration: DO-15 axial through-hole package
• Electrical Characteristics: Clamping voltage in the 11.3V to 11.87V range
• Compliance: ROHS3 compliance and MSL Level 1 rating

All substitute parts listed maintain these core electrical and mechanical specifications, ensuring functional equivalence within the P6KE series TVS diode family.

Parameter Comparison

Engineering Selection Recommendations

P6KE7.5A (Taiwan Semiconductor Corporation) is the primary direct substitute. This part maintains identical reverse standoff voltage, equivalent clamping voltage performance, and full compliance with ROHS3 and MSL Level 1 requirements. Product status is active with 7700 units in stock, ensuring long-term availability.

P6KE7.5A-TP (Micro Commercial Co) is the manufacturer-recommended alternative, offered in Cut Tape packaging. Electrical parameters are equivalent to P6KE7.5A with marginally lower peak pulse current (53A vs 55A). This option is suitable for applications where tape packaging is preferred for automated assembly.

P6KE7V5A (Taiwan Semiconductor Corporation) is a manufacturer-recommended option with active product status. Electrical characteristics align with the P6KE7.5A variant. Operating temperature range is not specified for this part number variant.

All three substitute parts are ROHS3 compliant and carry MSL Level 1 moisture sensitivity rating, matching the original P6KE7.5 compliance profile.

Frequently Asked Questions (FAQ)

Q: Can P6KE7.5A directly replace P6KE7.5 in existing designs?

A: Yes. Both parts share identical reverse standoff voltage (6.4V), equivalent clamping voltage performance (11.3V vs 11.87V), 600W power rating, and DO-15 through-hole package configuration. The primary difference is the original part is obsolete while P6KE7.5A is in active production.

Q: What is the difference between P6KE7.5A and P6KE7.5A-TP?

A: Electrical specifications are equivalent. The primary difference is packaging: P6KE7.5A is supplied in standard packaging, while P6KE7.5A-TP is supplied in Cut Tape format. Peak pulse current is marginally lower in the TP variant (53A vs 55A).

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts are ROHS3 compliant with MSL Level 1 moisture sensitivity rating, matching the original P6KE7.5 compliance requirements.

Q: Does clamping voltage variation affect circuit compatibility?

A: Clamping voltage differences between 11.3V and 11.87V are within the same protection class for 6V standoff TVS diodes. Selection should be based on specific circuit overvoltage protection requirements and maximum allowable transient voltage limits.

Q: What is the availability status of substitute parts?

A: P6KE7.5A has 7700 units in stock, P6KE7.5A-TP has 4678 units in stock, and P6KE7V5A has 936 units in stock. All are listed as active products with ongoing manufacturing support.
