15KP60CA-TP Equivalent & Substitute Parts

Part Overview

The 15KP60CA-TP is a transient voltage suppressor (TVS) diode manufactured by Micro Commercial Co, designed for general-purpose overvoltage protection applications. This bidirectional zener diode operates with a 60V reverse standoff voltage and delivers 15kW peak pulse power in an axial through-hole R-6 package. The component is ROHS3 compliant and maintains active product status, making it suitable for immediate deployment in protection circuits requiring reliable transient suppression.

Substitute parts become necessary when the original manufacturer part is unavailable, when alternative packaging formats are preferred, or when application requirements demand different power dissipation or current handling characteristics within the same voltage class.

Engineering Selection Recommendations

15KPA60CA (MDE Semiconductor Inc): Direct electrical equivalent with identical 15kW power rating and matching clamping voltage (97.4V). Differs only in package format (P600 vs. R-6) and packaging method (Bulk vs. Tape & Reel). All compliance certifications align with the main part. Suitable for direct substitution where P600 axial package is mechanically compatible.

30KPA60CA (MDE Semiconductor Inc): Maintains identical voltage specifications but provides doubled power dissipation (30kW vs. 15kW) with proportionally higher peak pulse current (297.1A). Clamping voltage rises to 102V, remaining within acceptable engineering tolerance. Appropriate for applications requiring enhanced transient energy absorption or where thermal margin is critical. Package format is P600 axial.

5KP60CA (Littelfuse Inc.): Reduced power rating (5kW vs. 15kW) with correspondingly lower peak pulse current (52.7A). Clamping voltage (96.8V) remains within specification tolerance. Suitable only for lower-energy transient environments or space-constrained applications where 15kW dissipation is unnecessary. All compliance certifications are current. Package format is P600 axial.

All substitute parts maintain ROHS3 compliance, active product status, and identical operating temperature range (-55°C to 175°C).

Frequently Asked Questions (FAQ)

Q: Can 15KPA60CA replace 15KP60CA-TP directly? A: Yes. Both parts share identical electrical specifications (60V standoff, 97.3-97.4V clamping, 15kW power). The primary difference is package format: 15KPA60CA uses P600 axial case versus R-6 for the original. Verify mechanical fit in your PCB layout before substitution.

Q: What is the difference between the 5KP60CA and 15KP60CA-TP? A: The 5KP60CA has one-third the power dissipation (5kW vs. 15kW) and lower peak pulse current (52.7A vs. unspecified for the main part). Voltage specifications remain identical. Use 5KP60CA only in applications with lower transient energy requirements.

Q: When should I use the 30KPA60CA instead of the 15KP60CA-TP? A: The 30KPA60CA doubles the power handling capability (30kW vs. 15kW) and increases peak pulse current to 297.1A. Select this part when your application experiences high-energy transients or when thermal margin is a design concern. Clamping voltage increases slightly to 102V, which remains acceptable for 60V protection circuits.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts (15KPA60CA, 30KPA60CA, 5KP60CA) are ROHS3 compliant and maintain active product status, matching the compliance profile of the 15KP60CA-TP.

Q: Does package format affect electrical performance? A: No. R-6 and P600 are both axial through-hole packages with identical electrical characteristics. Package selection is determined by PCB layout constraints and mechanical compatibility, not electrical performance.

Q: What is the significance of the clamping voltage variation (96.8V to 102V)? A: All clamping voltages fall within acceptable engineering tolerance for 60V protection circuits. The variation reflects normal manufacturing tolerances across different manufacturers. Select based on your specific circuit's voltage margin requirements.
