Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete P6KE480 with the P6KE480A is based on electrical parameter equivalence and mechanical compatibility. Both components share identical specifications across all critical performance parameters: reverse standoff voltage (408V), breakdown voltage (456V minimum), clamping voltage (658V maximum), peak pulse current (900mA), and peak pulse power (600W). Both devices utilize the same through-hole DO-204AC (DO-15) axial package, ensuring direct mechanical compatibility in existing PCB layouts. The substitution is valid based on matching voltage ratings, current handling capacity, and package form factor. The P6KE480A is manufactured by Good-Ark Semiconductor and maintains active product status, providing supply continuity for the P6KE480 application requirements.

Parameter Comparison

Engineering Selection Recommendations

The P6KE480A from Good-Ark Semiconductor is a direct electrical and mechanical equivalent to the obsolete P6KE480. Selection of the P6KE480A is appropriate for applications requiring identical voltage suppression characteristics and through-hole axial package compatibility.

The primary consideration is the operating temperature range. The P6KE480 supports operation to 175°C junction temperature, while the P6KE480A is rated to 150°C. For applications operating within the -55°C to 150°C range, the P6KE480A provides full functional equivalence. Applications requiring sustained operation above 150°C junction temperature require thermal analysis to confirm the P6KE480A remains within acceptable operating limits or alternative component selection.

Both components maintain RoHS compliance and unlimited moisture sensitivity classification (MSL 1), supporting deployment in standard manufacturing and storage environments. The P6KE480A is currently in active production status with established supply availability, providing long-term sourcing stability compared to the obsolete P6KE480.

Frequently Asked Questions (FAQ)

Q: Can the P6KE480A be used as a direct replacement for the P6KE480 in existing designs?

A: Yes, the P6KE480A provides direct electrical and mechanical substitution for the P6KE480. Both components share identical voltage ratings (408V standoff, 658V clamping), current capacity (900mA peak pulse), power dissipation (600W), and package configuration (DO-204AC through-hole axial). No circuit modifications are required for substitution.

Q: What is the difference in operating temperature range between these components?

A: The P6KE480 operates from -55°C to 175°C junction temperature, while the P6KE480A operates from -55°C to 150°C. The P6KE480A has a 25°C lower maximum junction temperature rating. Applications operating within the -55°C to 150°C range experience no functional difference. Applications requiring operation above 150°C must evaluate thermal conditions to determine if the P6KE480A remains suitable.

Q: Are there packaging differences between the P6KE480 and P6KE480A?

A: No. Both components use the DO-204AC (DO-15) through-hole axial package. Physical dimensions, lead spacing, and PCB mounting requirements are identical, enabling direct board-level substitution without layout modifications.

Q: What compliance certifications apply to the P6KE480A?

A: The P6KE480A is ROHS3 compliant and carries MSL 1 (unlimited moisture sensitivity level) classification. These certifications support use in standard manufacturing environments and storage conditions without special handling requirements.

Q: Why is the P6KE480 classified as obsolete?

A: The P6KE480 is no longer in active production. The P6KE480A from Good-Ark Semiconductor provides equivalent electrical performance and maintains active production status, ensuring continued availability for new designs and legacy system support.

Q: Are there any electrical performance differences between the two components?

A: No. Both components are specified identically across all electrical parameters: reverse standoff voltage, breakdown voltage, clamping voltage, peak pulse current, and peak pulse power. Electrical performance is equivalent.
