30KPA70CE3/TR13 Equivalent & Substitute Parts

Part Overview

The 30KPA70CE3/TR13 is a transient voltage suppressor (TVS) diode manufactured by Microchip Technology, classified as a Zener-type bidirectional TVS device in P600 axial through-hole packaging. This component is designed for general-purpose transient voltage suppression applications with a reverse standoff voltage of 70V and peak pulse power rating of 30kW. The part is currently in active product status with RoHS3 compliance and unlimited moisture sensitivity level (MSL 1).

Equivalent and substitute parts are identified to address supply chain requirements, inventory availability, or specific application parameter needs while maintaining functional compatibility within the 70V reverse standoff voltage class and P600 package form factor.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 30KPA70CE3/TR13 are identified based on the following critical parameters that determine functional compatibility:

Primary Matching Criteria:

• Reverse Standoff Voltage (Typ): 70V
• Package / Case: P600, Axial
• Mounting Type: Through Hole
• Bidirectional Channels: 1
• Type: Zener

Secondary Compatibility Parameters:

• Breakdown Voltage (Min): Range 73.71V to 78.2V
• Operating Temperature Range: -55°C to 175°C (TJ)
• Peak Pulse Power: 5000W to 30000W (power derating acceptable for lower-power applications)

Substitutes are grouped into two categories:

Direct Substitutes (Same Power Rating): Parts maintaining the 30kW peak pulse power specification, allowing direct replacement without circuit redesign.

Functional Substitutes (Lower Power Rating): Parts with reduced peak pulse power (5kW to 15kW) suitable for applications where the full 30kW capability is not required, provided the actual transient energy does not exceed the substitute part's rating.

Parameter Comparison

Engineering Selection Recommendations

30KPA70CA (Direct Substitute): The 30KPA70CA from MDE Semiconductor Inc is a direct substitute for the 30KPA70CE3/TR13. Both devices maintain identical reverse standoff voltage (70V), peak pulse power (30kW), operating temperature range (-55°C to 175°C), and P600 axial through-hole package specification. The 30KPA70CA is ROHS3 compliant and carries active product status. This substitute is appropriate for applications requiring the full 30kW transient suppression capability without circuit modification.

15KPA70CA (Functional Substitute): The 15KPA70CA from MDE Semiconductor Inc is a functional substitute suitable for applications where peak pulse power requirements do not exceed 15kW. This device maintains the 70V reverse standoff voltage, P600 package, and operating temperature range. The 15KPA70CA is ROHS3 compliant and active. Selection of this substitute requires confirmation that actual transient energy in the application does not exceed 15kW peak pulse power.

5KP70CA (Functional Substitute): The 5KP70CA from Diotec Semiconductor is a functional substitute for applications with peak pulse power requirements not exceeding 5kW. This device maintains the 70V reverse standoff voltage and P600 axial through-hole package. The operating temperature range is -50°C to 175°C (TJ), which is acceptable for most general-purpose applications. RoHS compliance status is not applicable for this part. Selection requires confirmation that actual transient energy does not exceed 5kW peak pulse power.

Frequently Asked Questions (FAQ)

Q: Can the 30KPA70CA be used as a direct replacement for the 30KPA70CE3/TR13?

A: Yes. The 30KPA70CA is a direct substitute. Both devices share identical electrical specifications (70V reverse standoff, 30kW peak pulse power), operating temperature range (-55°C to 175°C), and P600 axial through-hole package. The primary difference is packaging format (Tape & Reel versus Bulk) and manufacturer. No circuit modification is required.

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

A: The primary difference is peak pulse power rating. The 30KPA70CA is rated for 30kW peak pulse power with 278A peak pulse current, while the 15KPA70CA is rated for 15kW peak pulse power with 132.9A peak pulse current. Both maintain the same 70V reverse standoff voltage and P600 package. The 15KPA70CA is suitable only for applications where transient energy does not exceed 15kW.

Q: Can I use the 5KP70CA in place of the 30KPA70CE3/TR13?

A: The 5KP70CA can be used only if the application's actual peak pulse power requirement does not exceed 5kW. The 5KP70CA maintains the 70V reverse standoff voltage and P600 package but has significantly reduced power handling capability (5kW versus 30kW). Using this substitute in a high-energy transient environment will result in device failure. Confirm application transient energy specifications before selection.

Q: Are all substitute parts available in the same packaging format?

A: No. The 30KPA70CE3/TR13 is supplied in Tape & Reel (TR) format. The 30KPA70CA and 15KPA70CA are supplied in Bulk packaging. The 5KP70CA packaging format is not specified. Verify packaging requirements for automated assembly or manual installation processes before final part selection.

Q: Do all substitute parts meet RoHS3 compliance?

A: The 30KPA70CA and 15KPA70CA are both ROHS3 compliant. The 5KP70CA has RoHS status listed as "Not applicable." If RoHS3 compliance is a requirement for your application, the 5KP70CA is not suitable.

Q: What is the operating temperature range difference between the main part and substitutes?

A: The 30KPA70CE3/TR13, 30KPA70CA, and 15KPA70CA all operate from -55°C to 175°C (TJ). The 5KP70CA operates from -50°C to 175°C (TJ), with a 5°C higher minimum temperature limit. For applications requiring operation below -50°C, the 5KP70CA is not suitable.

Q: Can I mix different substitute parts in the same circuit board?

A: Yes, provided each location in the circuit is designed for the specific power rating of the part installed. Mixing 30kW, 15kW, and 5kW rated devices on the same board is acceptable if different circuit branches have different transient energy requirements. However, ensure that each branch's transient energy does not exceed the installed device's power rating.
