30KP70CA-TP Equivalent & Substitute Parts

Part Overview

The 30KP70CA-TP is a Transient Voltage Suppressor (TVS) diode manufactured by Micro Commercial Co, designed for general-purpose transient voltage protection in through-hole applications. This bidirectional zener diode operates with a 70V reverse standoff voltage and provides 30kW peak pulse power dissipation. The component is Active in product status and fully ROHS3 compliant. Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained across the specified parameter range.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 30KP70CA-TP is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff (Typ): 70V
• Voltage - Breakdown (Min): 78.2V
• Voltage - Clamping (Max) @ Ipp: 109V
• Power - Peak Pulse: 30000W (30kW)
• Mounting Type: Through Hole
• Operating Temperature Range: -55°C ~ 175°C (TJ)
• Type: Zener, Bidirectional (1 channel)
• RoHS Compliance: ROHS3 Compliant

The substitute parts 15KPA70CA and 30KPA70CA are identified based on matching voltage specifications and thermal operating range. The 30KPA70CA maintains identical electrical performance at the 30kW power level. The 15KPA70CA operates at reduced peak pulse power (15kW) and represents a lower-power alternative where full 30kW dissipation is not required.

Parameter Comparison

Engineering Selection Recommendations

30KPA70CA (Primary Substitute): This part maintains identical voltage clamping (109V) and peak pulse power (30kW) specifications as the 30KP70CA-TP. Both components are Active in product status and ROHS3 compliant. The primary difference is the package type (P600 vs. R-6 axial) and manufacturer (MDE Semiconductor Inc vs. Micro Commercial Co). Selection of this substitute requires PCB layout compatibility with the P600 package footprint.

15KPA70CA (Lower-Power Alternative): This part matches the voltage specifications (70V standoff, 78.2V breakdown) but operates at reduced peak pulse power (15kW vs. 30kW). The clamping voltage is slightly elevated at 113.6V. This substitute is suitable only for applications where peak pulse power requirements do not exceed 15kW. Both components are Active and ROHS3 compliant.

All substitute parts maintain the required operating temperature range (-55°C ~ 175°C) and through-hole mounting configuration. Component selection must account for package footprint differences and application-specific power dissipation requirements.

Frequently Asked Questions (FAQ)

Q: Can the 30KPA70CA directly replace the 30KP70CA-TP?

A: Electrical substitution is valid based on matching voltage specifications (70V standoff, 109V clamping) and identical 30kW peak pulse power rating. Physical substitution requires PCB layout compatibility with the P600 axial package, which differs from the R-6 package of the original part.

Q: What is the difference between the 15KPA70CA and 30KPA70CA substitutes?

A: The primary difference is peak pulse power rating: 15KPA70CA is rated for 15kW, while 30KPA70CA is rated for 30kW. Both maintain the same 70V reverse standoff voltage and 78.2V minimum breakdown voltage. The 15KPA70CA exhibits a slightly higher clamping voltage (113.6V vs. 109V). Selection depends on application power dissipation requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. The 30KP70CA-TP, 15KPA70CA, and 30KPA70CA are all ROHS3 compliant, meeting regulatory requirements for hazardous substance restrictions.

Q: What is the operating temperature range for these TVS diodes?

A: All three parts operate across the same temperature range: -55°C to 175°C (junction temperature). This range is maintained across all substitute options.

Q: Does package type affect electrical performance?

A: Package type (R-6 vs. P600 axial) does not affect electrical performance. However, physical dimensions and PCB footprint compatibility must be verified during design integration to ensure mechanical fit and thermal management requirements are met.

Q: What determines whether a part can substitute for the 30KP70CA-TP?

A: Substitution is determined by equivalence in reverse standoff voltage (70V), breakdown voltage (78.2V), clamping voltage (109V for full-power applications), peak pulse power rating, operating temperature range, and through-hole mounting type. All substitute parts must maintain ROHS3 compliance and Active product status.
