30KP48CA-TP Equivalent & Substitute Parts

Part Overview

The 30KP48CA-TP is a transient voltage suppressor (TVS) diode manufactured by Micro Commercial Co, designed for general-purpose overvoltage protection applications. This through-hole axial component operates with a 48V reverse standoff voltage and provides 30kW peak pulse power dissipation capability. The part is currently active in production and ROHS3 compliant. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, manufacturing discontinuation, or application-specific packaging preferences.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 30KP48CA-TP is determined by the following critical parameters:

• Voltage - Reverse Standoff (Typ): Must equal 48V
• Voltage - Breakdown (Min): Must equal 53.6V
• Mounting Type: Must be Through Hole
• Bidirectional Channels: Must equal 1
• Type: Must be Zener
• Operating Temperature Range: Must encompass -55°C to 175°C or equivalent

Substitute parts are grouped into two categories:

Direct Substitutes (identical clamping voltage and power rating):

• 30KPA48CA: Matches all critical electrical parameters with 81.6V clamping voltage and 30kW power rating. Package variant P600 (axial) is mechanically compatible with R-6 axial configuration.

Similar Substitutes (compatible voltage standoff with reduced power or clamping specifications):

• 15KPA48CA: Maintains 48V standoff and 53.6V breakdown but reduces clamping voltage to 77.7V and power to 15kW. Suitable for applications with lower transient energy requirements.
• 5KP48CA: Reduces power rating to 5kW with 77.4V clamping voltage. Suitable for lower-energy transient suppression.
• 5KP48CA-B: Equivalent to 5KP48CA with 77.4V clamping and 5kW power rating.

Parameter Comparison

Engineering Selection Recommendations

30KPA48CA is the primary direct substitute for 30KP48CA-TP. Both parts maintain identical electrical specifications (48V standoff, 53.6V breakdown, 81.6V clamping, 30kW power) and are ROHS3 compliant with active product status. The P600 axial package is mechanically compatible with the R-6 axial configuration. This substitute is recommended when MDE Semiconductor Inc inventory is available and packaging format is acceptable.

15KPA48CA is suitable for applications where transient energy is limited to 15kW. This part maintains the critical 48V standoff voltage and 53.6V breakdown specification but reduces clamping voltage to 77.7V. Selection of this substitute requires confirmation that the application can tolerate the lower clamping voltage and power dissipation capability. ROHS3 compliance and active status are maintained.

5KP48CA and 5KP48CA-B are applicable only to applications requiring 5kW peak pulse power dissipation. Both maintain the 48V standoff voltage but feature 77.4V clamping voltage. The 5KP48CA-B variant from Littelfuse Inc. is preferred due to extended operating temperature range (-55 to 175°C) matching the main part specification. Selection requires confirmation that application transient energy does not exceed 5kW.

All substitute parts are ROHS3 compliant and carry active product status, ensuring regulatory compliance and manufacturing availability.

Frequently Asked Questions (FAQ)

Q: Can 30KPA48CA directly replace 30KP48CA-TP in all applications?

A: Yes. Both parts share identical electrical specifications: 48V reverse standoff voltage, 53.6V breakdown voltage, 81.6V clamping voltage, and 30kW peak pulse power. The P600 axial package is mechanically compatible with R-6 axial through-hole mounting. No circuit redesign is required.

Q: What is the difference between 30KPA48CA and 15KPA48CA?

A: The primary difference is power dissipation capability. 30KPA48CA handles 30kW peak pulse power with 81.6V clamping voltage. 15KPA48CA handles 15kW peak pulse power with 77.7V clamping voltage. Both maintain 48V standoff voltage. Selection depends on the transient energy level in the application.

Q: Can 5KP48CA be used instead of 30KP48CA-TP?

A: Only if the application transient energy does not exceed 5kW. The 5KP48CA reduces power dissipation from 30kW to 5kW and clamping voltage from 81.6V to 77.4V. Using this part in a 30kW application will result in component failure.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification, matching the main part specification.

Q: What is the operating temperature range for each substitute?

A: 30KPA48CA, 15KPA48CA, and 5KP48CA-B all operate from -55°C to 175°C, matching the main part. 5KP48CA operates from -50°C to 175°C, which is acceptable for most applications but does not extend to the lower temperature limit of the main part.

Q: Are the axial package variants (R-6 vs. P600) interchangeable on PCBs?

A: Yes. Both R-6 and P600 are axial through-hole packages with compatible lead spacing and mounting footprints. No PCB redesign is required for package substitution.
