P6KE7.5C-B Equivalent & Substitute Parts

Part Overview

The P6KE7.5C-B is a Transient Voltage Suppressor (TVS) diode manufactured by Littelfuse, rated for 600W peak pulse power with a 6.4V reverse standoff voltage and 11.87V maximum clamping voltage. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. The P6KE series provides general-purpose transient voltage suppression in a through-hole DO-204AC (DO-15) axial package format.

• Reverse Standoff Voltage: 6.4V (Typ)
• Breakdown Voltage (Min): 6.75V or higher
• Clamping Voltage (Max) @ Ipp: 11.3V to 11.87V range
• Power - Peak Pulse: 600W
• Bidirectional Channels: 1
• Package / Case: DO-204AC (DO-15) Axial
• Operating Temperature Range: -55°C ~ 175°C (TJ)
• Type: Zener
• Mounting Type: Through Hole

The identified substitute parts maintain these electrical and mechanical specifications, ensuring direct functional replacement in existing circuit designs.

Parameter Comparison

Engineering Selection Recommendations

Both P6KE7.5CA-B and P6KE7.5CA are active product alternatives to the obsolete P6KE7.5C-B. The P6KE7.5CA-B, manufactured by Littelfuse Inc., maintains the same manufacturer lineage as the original part and carries active product status with ROHS3 compliance and REACH unaffected certification. The P6KE7.5CA, supplied by Taiwan Semiconductor Corporation, also maintains active status with equivalent ROHS3 compliance and REACH unaffected certification.

Both substitutes share identical reverse standoff voltage (6.4V), power rating (600W), operating temperature range (-55°C ~ 175°C), and package format (DO-204AC/DO-15 axial). The clamping voltage differential (11.3V versus 11.87V) and peak pulse current specifications (54A to 55A) fall within acceptable tolerance ranges for general-purpose transient voltage suppression applications.

Frequently Asked Questions (FAQ)

Q: Can P6KE7.5CA-B and P6KE7.5CA be used interchangeably with P6KE7.5C-B?

A: Yes. Both parts maintain the critical electrical parameters: 6.4V reverse standoff voltage, 600W peak pulse power, -55°C to 175°C operating temperature range, and identical DO-204AC (DO-15) axial package format. The clamping voltage difference (11.3V versus 11.87V) and peak pulse current specifications remain within functional equivalence for general-purpose applications.

Q: What is the primary reason for substitution?

A: The P6KE7.5C-B is classified as obsolete. The P6KE7.5CA-B and P6KE7.5CA are active products with confirmed availability and ongoing manufacturer support.

Q: Are there compliance differences between the substitute parts?

A: All three parts are ROHS3 compliant. The P6KE7.5CA-B and P6KE7.5CA both carry REACH unaffected certification, providing additional regulatory assurance for new designs.

Q: Does the manufacturer difference between Littelfuse and Taiwan Semiconductor Corporation affect compatibility?

A: No. Both manufacturers supply parts within the P6KE series with identical electrical specifications and package format. The parts are functionally equivalent for circuit design purposes.

Q: Are there packaging format differences?

A: No. All three parts use the same DO-204AC (DO-15) axial through-hole package, ensuring direct mechanical compatibility in existing PCB layouts.
