30KP70A-TP Transient Voltage Suppressor Equivalent & Substitute Parts

Part Overview

The 30KP70A-TP is an active Transient Voltage Suppressor (TVS) diode manufactured by Micro Commercial Co, designed for general-purpose overvoltage protection applications. This unidirectional Zener diode operates with a 70V reverse standoff voltage and provides 30kW peak pulse power dissipation in an R-6 axial through-hole package. The part is ROHS3 compliant and carries unlimited moisture sensitivity rating (MSL 1), making it suitable for standard industrial and commercial electronic protection circuits.

Equivalent and substitute parts are necessary when the original 30KP70A-TP becomes unavailable, when alternative packaging formats are required, or when different power dissipation levels are needed for specific circuit requirements while maintaining core voltage protection parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 30KP70A-TP is determined by the following critical parameters:

• Voltage - Reverse Standoff: Must be 70V (all substitutes match this requirement)
• Voltage - Breakdown (Min): Must be within 77.8V to 78.2V range (all substitutes comply)
• Voltage - Clamping (Max) @ Ipp: Must be 109V to 113.6V (acceptable range for protection circuits)
• Type: Must be Zener diode, unidirectional configuration
• Mounting Type: Through Hole axial package (R-6 or P600 variants acceptable)
• Operating Temperature Range: Must support -55°C ~ 175°C (TJ)
• RoHS Compliance: ROHS3 compliant status required

The substitute parts listed below meet all mandatory electrical parameters. Power dissipation levels vary (5kW, 15kW, 30kW), allowing selection based on specific circuit pulse energy requirements. Package variants (R-6 vs P600) and packaging formats (Tape & Reel vs Bulk vs Cut Tape) provide flexibility for different procurement and assembly workflows.

Parameter Comparison

Engineering Selection Recommendations

30KPA70A (MDE Semiconductor Inc): Direct electrical equivalent with identical 30kW power dissipation and 109V clamping voltage. Differs only in package format (P600 vs R-6) and packaging type (Bulk vs Tape & Reel). ROHS3 compliant. Select when P600 axial package is acceptable for PCB layout and bulk packaging meets procurement requirements.

15KPA70A (MDE Semiconductor Inc): Maintains voltage parameters (70V standoff, 78.2V breakdown, 113.6V clamp) with reduced power dissipation (15kW). Suitable for applications where peak pulse energy is lower than 30kW specification. ROHS3 compliant. Select when circuit analysis confirms 15kW peak pulse capacity is sufficient.

5KP70A (Littelfuse Inc.): Maintains voltage parameters (70V standoff, 77.8V breakdown, 113V clamp) with lowest power dissipation (5kW). Suitable for low-energy transient protection applications. ROHS3 compliant with REACH Affected status. Select only when peak pulse energy requirement is confirmed at 5kW or below.

All substitutes maintain active product status and unlimited moisture sensitivity rating. Selection should be based on circuit peak pulse energy requirements and acceptable package/packaging formats for assembly and procurement workflows.

Frequently Asked Questions (FAQ)

Q: Can 30KPA70A replace 30KP70A-TP directly? A: Yes, electrically. Both provide 70V standoff voltage, 109V clamping voltage, and 30kW peak pulse power. The primary difference is package format (P600 vs R-6 axial) and packaging type (Bulk vs Tape & Reel). Verify PCB footprint compatibility before substitution.

Q: What is the difference between 30KP70A-TP and 15KPA70A? A: Both maintain identical voltage protection parameters (70V standoff, 78.2V breakdown). The 15KPA70A has half the peak pulse power rating (15kW vs 30kW). Use 15KPA70A only if circuit analysis confirms peak pulse energy does not exceed 15kW.

Q: Can 5KP70A be used instead of 30KP70A-TP? A: Only if peak pulse energy in the circuit is confirmed to be 5kW or below. All three parts provide the same 70V voltage protection, but 5KP70A has significantly lower power dissipation capacity. Oversizing protection (using 30kW when 5kW is needed) is acceptable; undersizing is not.

Q: Are all substitutes ROHS3 compliant? A: Yes. All listed substitutes (30KPA70A, 15KPA70A, 5KP70A) are ROHS3 compliant. The 5KP70A carries REACH Affected status; verify REACH compliance requirements for your application.

Q: What is the difference between R-6 and P600 packages? A: Both are axial through-hole packages for TVS diodes. R-6 is the original package for 30KP70A-TP. P600 is used by substitute manufacturers. Verify PCB pad spacing and hole diameter compatibility before substitution.

Q: Does packaging format (Tape & Reel vs Bulk vs Cut Tape) affect electrical performance? A: No. Packaging format affects procurement, storage, and assembly processes only. Electrical performance is identical. Select based on your assembly line requirements and inventory management practices.

Q: What happens if I use a lower power-rated substitute (5kW or 15kW) in a 30kW circuit? A: The diode will fail or degrade prematurely if peak pulse energy exceeds its power rating. Always confirm actual circuit peak pulse energy before selecting a lower-rated substitute.
