P6KE11A-T Equivalent & Substitute Parts

Part Overview

The P6KE11A-T is a unidirectional Transient Voltage Suppressor (TVS) diode manufactured by Diodes Incorporated, designed for general-purpose overvoltage protection in through-hole applications. This component features a 9.4V reverse standoff voltage, 15.6V maximum clamping voltage, and 38A peak pulse current capability in a DO-15 axial package. The part is classified as obsolete, necessitating identification of active equivalent alternatives that maintain electrical and mechanical compatibility for ongoing design support and production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution validity for the P6KE11A-T is determined by strict equivalence across the following critical parameters: reverse standoff voltage (9.4V), breakdown voltage minimum (10.5V), maximum clamping voltage (15.6V), peak pulse current (38A nominal), power dissipation (600W), unidirectional channel configuration (1), and through-hole mounting compatibility. All identified substitute parts maintain these electrical specifications. Package variants (DO-15, DO-204AC, Axial) are mechanically interchangeable within the through-hole form factor. Operating temperature range variations are noted where they differ from the main part specification. Compliance certifications (RoHS3, REACH status) are documented for each substitute to support procurement and regulatory requirements.

Parameter Comparison

Engineering Selection Recommendations

For direct replacement of the obsolete P6KE11A-T, the P6KE11A manufactured by Taiwan Semiconductor Corporation is the primary equivalent, offering identical electrical specifications and active product status. This part is available in tape and reel packaging with current inventory support.

The P6KE11A-AP and P6KE11A-BP variants from Micro Commercial Co provide active alternatives with matching electrical parameters and full operating temperature range alignment (-55°C ~ 175°C). Both are available in bulk packaging.

The P6KE11A-B from Littelfuse Inc. is a manufacturer-recommended substitute with marginally higher peak pulse current (39.1A versus 38A), maintaining all other electrical specifications. This part carries RoHS3 compliance and is packaged in DO-204AC format, which is mechanically compatible with DO-15 through-hole applications.

The P6KE11AE3/TR13 from Microsemi Corporation provides an active alternative in axial package format with identical electrical performance. Operating temperature range is -65°C ~ 150°C, which covers the lower end of the original specification but does not extend to the full 175°C maximum.

Selection should prioritize parts with active product status and confirmed RoHS3 compliance for new designs. Packaging format selection (DO-15, DO-204AC, or Axial) depends on PCB layout requirements and mechanical constraints.

Frequently Asked Questions (FAQ)

Q: Can P6KE11A from Taiwan Semiconductor Corporation directly replace P6KE11A-T?

A: Yes. Both parts share identical electrical specifications: 9.4V reverse standoff voltage, 10.5V minimum breakdown voltage, 15.6V maximum clamping voltage, and 38A peak pulse current. The Taiwan Semiconductor part is active and available, making it suitable for direct substitution in through-hole applications.

Q: What is the difference between P6KE11A-AP and P6KE11A-BP?

A: Both parts are manufactured by Micro Commercial Co with identical electrical specifications and operating temperature range (-55°C ~ 175°C). The suffix designations (-AP and -BP) indicate different manufacturing or packaging variants. Both are active and available in bulk packaging.

Q: Is P6KE11A-B from Littelfuse a suitable substitute despite the higher peak pulse current specification?

A: Yes. The P6KE11A-B specifies 39.1A peak pulse current compared to 38A in the original part. This represents a 2.9% increase and does not compromise compatibility. All other electrical parameters match exactly. The part is RoHS3 compliant and actively produced.

Q: Are DO-15 and DO-204AC packages mechanically interchangeable?

A: Yes. Both designations refer to the same axial through-hole package format. DO-15 and DO-204AC are equivalent package specifications for this component category. Axial package variants are also mechanically compatible with standard through-hole PCB layouts designed for this form factor.

Q: Does the P6KE11AE3/TR13 from Microsemi meet the full operating temperature range of the original part?

A: The P6KE11AE3/TR13 specifies -65°C ~ 150°C operating temperature, which does not extend to the 175°C maximum of the original P6KE11A-T. If applications require operation at temperatures above 150°C, alternative substitutes with -55°C ~ 175°C range (P6KE11A, P6KE11A-AP, P6KE11A-BP, or P6KE11A-B) are required.

Q: What compliance certifications should be verified for procurement?

A: RoHS3 compliance is confirmed for P6KE11A-T, P6KE11A, P6KE11A-B, and P6KE11AE3/TR13. REACH status varies by manufacturer. Verify specific compliance documentation with the selected supplier to confirm regulatory requirements for your application and region.
