30KP102A-TP Equivalent & Substitute Parts

Part Overview

The 30KP102A-TP is a unidirectional Transient Voltage Suppressor (TVS) diode manufactured by Micro Commercial Co, designed for general-purpose transient protection applications. This through-hole component features a 102V reverse standoff voltage with a 165.6V maximum clamping voltage and 30kW peak pulse power rating. The part is Active in product status and ROHS3 compliant, making it suitable for modern electronic circuit protection requirements. Equivalent and substitute parts are identified to provide design flexibility, inventory alternatives, and sourcing options while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 30KP102A-TP is determined by the following critical parameters:

• Voltage - Reverse Standoff (Typ): 102V
• Voltage - Breakdown (Min): 113.9V minimum
• Voltage - Clamping (Max) @ Ipp: 165.6V maximum
• Power - Peak Pulse: 30000W (30kW)
• Type: Zener, Unidirectional
• Mounting Type: Through Hole
• Operating Temperature Range: -55°C ~ 175°C (TJ)
• RoHS Status: ROHS3 Compliant

Two substitute parts meet these criteria: the 30KPA102A (MDE Semiconductor Inc) and the 1.5KE120A (Taiwan Semiconductor Corporation). Both maintain identical voltage specifications and temperature operating ranges. The 30KPA102A preserves the 30kW power rating in an alternative package configuration. The 1.5KE120A operates at reduced power (1.5kW) but maintains voltage compatibility for applications where peak pulse power requirements are lower.

Parameter Comparison

Engineering Selection Recommendations

All three parts—30KP102A-TP, 30KPA102A, and 1.5KE120A—are Active products with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component selection.

The 30KPA102A provides direct electrical equivalence with identical voltage specifications (102V standoff, 113.9V breakdown, 165.6V clamping) and 30kW power rating. Selection of this substitute is appropriate when the P600 package footprint is compatible with circuit board layout requirements.

The 1.5KE120A maintains voltage compatibility (102V standoff, 114V breakdown, 165V clamping) but operates at 1.5kW peak pulse power. This substitute is suitable for applications where transient energy levels are lower than the 30kW specification of the primary part, and where the DO-201 package configuration aligns with board design constraints.

Frequently Asked Questions (FAQ)

Q: Can the 30KPA102A directly replace the 30KP102A-TP?

A: Yes, the 30KPA102A is electrically equivalent, maintaining identical voltage specifications (102V reverse standoff, 113.9V breakdown minimum, 165.6V clamping maximum) and 30kW power rating. The primary difference is the package configuration: R-6 versus P600. Verify that the P600 package footprint is compatible with your circuit board layout before substitution.

Q: Is the 1.5KE120A suitable as a substitute?

A: The 1.5KE120A is electrically compatible for voltage protection (102V standoff, 114V breakdown, 165V clamping) and operates across the same temperature range. However, its 1.5kW peak pulse power rating is significantly lower than the 30kW specification. Use this substitute only in applications where peak transient energy does not exceed 1.5kW. The DO-201 package differs from the R-6 package of the primary part.

Q: What are the key parameters that determine substitution compatibility?

A: Substitution compatibility is determined by: reverse standoff voltage (102V), breakdown voltage minimum (113.9V), clamping voltage maximum (165.6V), unidirectional channel configuration (1), through-hole mounting type, and operating temperature range (-55°C to 175°C). Peak pulse power rating must meet or exceed application requirements. All substitute parts must maintain ROHS3 compliance and Active product status.

Q: Do package differences affect electrical performance?

A: Package differences (R-6, P600, DO-201) do not affect electrical performance but impact physical footprint, lead spacing, and board layout compatibility. Verify mechanical fit and lead configuration before substitution. All packages are axial through-hole configurations suitable for traditional PCB mounting.

Q: Are all substitute parts ROHS3 compliant?

A: Yes, the 30KP102A-TP, 30KPA102A, and 1.5KE120A are all ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), meeting current environmental and regulatory standards for electronic component manufacturing and use.
