P6KE30 Transient Voltage Suppressor (TVS) Equivalent & Substitute Parts

Part Overview

The P6KE30 is a unidirectional Zener transient voltage suppressor diode in DO-15 (DO-204AC) axial package designed for general-purpose overvoltage protection applications. The original Littelfuse P6KE30 is classified as obsolete, necessitating identification of active equivalent parts that maintain electrical and mechanical compatibility for circuit protection requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P6KE30 is determined by the following critical electrical and mechanical parameters:

• Voltage - Reverse Standoff (Typ): Must be 25.6V
• Voltage - Clamping (Max) @ Ipp: Must be within the range 41.4V to 43.47V
• Power - Peak Pulse: Must be 600W
• Package / Case: Must be DO-204AC, DO-15, or Axial equivalent
• Mounting Type: Must be Through Hole
• Type: Must be Zener unidirectional TVS diode
• RoHS Compliance: Must maintain ROHS3 Compliant status

All identified substitute parts meet these criteria and are classified as active products with current manufacturing status.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain electrical equivalence within the specified parameter tolerances for the P6KE30. Selection should be based on the following factors:

Product Status: P6KE30A (Taiwan Semiconductor Corporation), P6KE30A-G (Comchip Technology), and P6KE30A-HF (Comchip Technology) are all active products with current manufacturing support, ensuring long-term availability and supply chain continuity.

Compliance: All substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, matching the original part's environmental specifications.

Clamping Voltage: Substitute parts exhibit clamping voltages of 41.4V, which is within acceptable tolerance relative to the original 43.47V specification for general-purpose transient protection applications.

Packaging: All substitutes are supplied in DO-15 axial through-hole package format, maintaining mechanical compatibility with existing PCB layouts and assembly processes.

Frequently Asked Questions (FAQ)

Q: Can P6KE30A be used as a direct replacement for P6KE30?

A: Yes. P6KE30A meets all critical electrical parameters: 25.6V reverse standoff voltage, 41.4V clamping voltage, and 600W peak pulse power rating. The part is supplied in DO-15 package and maintains through-hole mounting compatibility.

Q: What is the difference between P6KE30A, P6KE30A-G, and P6KE30A-HF?

A: All three parts share identical electrical specifications (25.6V standoff, 41.4V clamping, 600W power rating). Differences are limited to manufacturer (Taiwan Semiconductor Corporation versus Comchip Technology) and packaging format (Cut Tape versus Tape & Box). The P6KE30A-HF designation indicates the P6KE-HF series variant from Comchip Technology.

Q: Are there operating temperature differences between substitutes?

A: P6KE30A-G and P6KE30A-HF specify operating temperature range of -55°C to 150°C. The original P6KE30 specifies -55°C to 175°C. For applications requiring operation above 150°C, verify thermal requirements against actual circuit conditions.

Q: Do all substitutes maintain RoHS compliance?

A: Yes. All substitute parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, matching the original part's environmental certifications.

Q: What packaging formats are available for substitutes?

A: P6KE30A is supplied in Cut Tape (CT) format. P6KE30A-G and P6KE30A-HF are supplied in Tape & Box (TB) format. All maintain DO-15 axial package configuration for through-hole PCB assembly.
