30KP58CA-TP Equivalent & Substitute Parts

Part Overview

The 30KP58CA-TP is a Transient Voltage Suppressor (TVS) diode manufactured by Micro Commercial Co, designed for general-purpose voltage protection applications. This through-hole axial component operates with a 58V reverse standoff voltage and provides 30kW peak pulse power dissipation. The part is Active status and ROHS3 compliant, making it suitable for modern electronic designs requiring transient suppression across a wide operating temperature range of -55°C to 175°C.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained across the critical voltage and power parameters that define TVS diode functionality in circuit protection applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 30KP58CA-TP are classified based on electrical parameter equivalence within the TVS diode category. The substitution logic is determined by the following critical parameters:

Voltage Parameters: Reverse standoff voltage (58V), breakdown voltage minimum (64.8V), and clamping voltage maximum (92.4V) must remain consistent to ensure proper circuit protection thresholds.

Power Rating: Peak pulse power dissipation of 30kW defines the thermal and current-handling capability required for the application.

Mechanical Compatibility: Through-hole mounting and axial package configuration ensure physical fit within existing circuit board designs.

Environmental Compliance: ROHS3 compliance and operating temperature range (-55°C to 175°C) must be maintained.

Parts are grouped as Direct Substitutes when all electrical parameters and package specifications match exactly. Parts are grouped as Similar Substitutes when voltage parameters remain equivalent but power ratings or peak pulse current specifications differ, indicating suitability for applications with reduced transient energy requirements.

Parameter Comparison

Engineering Selection Recommendations

30KPA58CA (Direct Substitute): This part maintains identical electrical specifications including 58V reverse standoff, 92.4V clamping voltage, and 30kW peak pulse power rating. Both parts are Active status and ROHS3 compliant. The primary difference is packaging format (P600 vs. R-6 axial) and manufacturer (MDE Semiconductor Inc vs. Micro Commercial Co). Selection of this substitute requires verification of physical package compatibility with existing board layouts, as the P600 package may have different lead spacing or dimensions compared to the R-6 package.

15KPA58CA (Similar Substitute): This part maintains the same 58V reverse standoff and 64.8V breakdown voltage specifications. The clamping voltage is 93.8V (compared to 92.4V) and the peak pulse power rating is reduced to 15kW (compared to 30kW). This part is suitable for applications where transient energy levels are lower than the original design specification. Both parts are Active status and ROHS3 compliant. Selection requires confirmation that the reduced power rating and slightly higher clamping voltage are acceptable for the intended circuit protection function.

Frequently Asked Questions (FAQ)

Q: Can 30KPA58CA be used as a direct replacement for 30KP58CA-TP?

A: The 30KPA58CA maintains identical electrical parameters (58V standoff, 92.4V clamping, 30kW power). However, the package differs (P600 vs. R-6 axial). Physical compatibility with the circuit board layout must be verified before substitution.

Q: What is the difference between the 30KPA58CA and 15KPA58CA?

A: Both parts share the same 58V reverse standoff voltage. The 30KPA58CA provides 30kW peak pulse power with 327.9A peak pulse current, while the 15KPA58CA provides 15kW peak pulse power with 161A peak pulse current. The 15KPA58CA also has a slightly higher clamping voltage of 93.8V versus 92.4V. Selection depends on the transient energy levels in the application.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. The main part 30KP58CA-TP and both substitute parts (30KPA58CA and 15KPA58CA) are ROHS3 compliant.

Q: What operating temperature range do these parts support?

A: All three parts operate across the same temperature range: -55°C to 175°C (TJ).

Q: Do package differences affect electrical performance?

A: Package differences (R-6 vs. P600 axial) do not affect electrical performance. However, they may affect physical fit on the circuit board and lead spacing. Board layout compatibility must be verified.

Q: Can 15KPA58CA be used in place of 30KP58CA-TP?

A: The 15KPA58CA can be used only if the application can tolerate a 50% reduction in peak pulse power handling (15kW vs. 30kW) and a slightly higher clamping voltage (93.8V vs. 92.4V). This substitution is suitable for lower-energy transient protection scenarios.
