15KP45CA-TP Transient Voltage Suppressor (TVS) Diode - Equivalent & Substitute Parts

Part Overview

The 15KP45CA-TP is an active, ROHS3 compliant Zener-type transient voltage suppressor manufactured by Micro Commercial Co. This through-hole axial TVS diode is designed for general-purpose transient voltage suppression applications with a 45V reverse standoff rating and 15kW peak pulse power handling capability. The part is available in R-6 package configuration and supplied in Tape & Reel format with 866 units currently in stock.

Equivalent and substitute parts are identified based on matching electrical characteristics including reverse standoff voltage, clamping voltage, bidirectional channel configuration, mounting type, and thermal operating range. Substitute parts may differ in peak pulse power rating, peak pulse current, package designation, and supplier packaging format while maintaining functional compatibility within the specified voltage and temperature parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 15KP45CA-TP are qualified based on the following critical electrical and mechanical parameters:

Primary Matching Criteria:

• Voltage - Reverse Standoff (Typ): 45V
• Voltage - Breakdown (Min): 50V or greater
• Bidirectional Channels: 1
• Mounting Type: Through Hole
• Operating Temperature Range: -55°C ~ 175°C (TJ)
• Type: Zener
• Product Status: Active

Secondary Compatibility Parameters:

• Voltage - Clamping (Max) @ Ipp: 72.7V to 77.4V (within acceptable transient suppression range)
• Power - Peak Pulse: 5000W to 30000W (substitutes may have different power ratings)
• Package / Case: Axial configuration (R-6 or P600 variants)
• RoHS Status: ROHS3 Compliant

All identified substitute parts maintain the core voltage suppression characteristics and thermal operating envelope of the main part while offering variations in peak pulse power handling and physical package dimensions.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain active product status and ROHS3 compliance, meeting regulatory requirements equivalent to the 15KP45CA-TP.

15KPA45CA (MDE Semiconductor Inc): Matches the 15kW peak pulse power rating of the main part with identical reverse standoff voltage (45V) and clamping voltage (72.8V). Supplied in bulk packaging with P600 axial package configuration. Suitable for direct functional replacement in applications requiring 15kW transient suppression.

30KPA45CA (MDE Semiconductor Inc): Provides enhanced peak pulse power handling at 30kW with matching 45V reverse standoff voltage. Clamping voltage of 77.4V remains within acceptable transient suppression parameters. Supplied in bulk packaging with P600 axial package configuration. Applicable for applications requiring higher transient energy dissipation capacity.

5KP45CA (Littelfuse Inc.): Offers reduced peak pulse power rating of 5kW with matching 45V reverse standoff voltage and 72.7V clamping voltage. Supplied in cut tape packaging with P600 axial package configuration. Suitable for lower-power transient suppression applications where 15kW capacity exceeds system requirements.

Frequently Asked Questions (FAQ)

Q: Can the 15KPA45CA replace the 15KP45CA-TP in my circuit?

A: Yes. Both parts share identical reverse standoff voltage (45V), breakdown voltage (50V minimum), clamping voltage (72.8V vs 73V), and peak pulse power rating (15kW). Operating temperature range and through-hole mounting type are equivalent. The primary difference is package designation (P600 vs R-6) and supplier packaging format (bulk vs tape & reel).

Q: What is the difference between the 5KP45CA and 15KP45CA-TP?

A: The 5KP45CA has a reduced peak pulse power rating of 5kW compared to the 15kW rating of the 15KP45CA-TP. All voltage parameters (45V reverse standoff, 50V breakdown minimum, 72.7V clamping) remain compatible. The 5KP45CA is suitable for applications with lower transient energy requirements.

Q: Why would I choose the 30KPA45CA over the 15KP45CA-TP?

A: The 30KPA45CA provides double the peak pulse power handling capacity (30kW vs 15kW) while maintaining the same 45V reverse standoff voltage. Selection depends on the peak transient energy levels in your application. Higher power rating provides additional margin for transient suppression.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. The 15KP45CA-TP and all identified substitute parts (15KPA45CA, 30KPA45CA, 5KP45CA) are ROHS3 compliant.

Q: Do package differences affect circuit compatibility?

A: Package differences (R-6 vs P600) are both axial through-hole configurations. Physical dimensions may vary, requiring verification of PCB layout and component spacing. Electrical performance and mounting type remain compatible.

Q: What is the operating temperature range for all parts?

A: All parts operate across the identical temperature range of -55°C to 175°C (junction temperature), ensuring thermal compatibility in equivalent applications.
