P6KE15CA-T Equivalent & Substitute Parts

Part Overview

The P6KE15CA-T is a transient voltage suppressor (TVS) diode manufactured by Diodes Incorporated, designed for general-purpose overvoltage protection in through-hole applications. This component features a 12.8V reverse standoff voltage, 21.2V maximum clamping voltage, and 28A peak pulse current capability in a DO-15 axial package. The part is currently obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the P6KE15CA-T is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff (Typ): 12.8V
• Voltage - Breakdown (Min): 14.3V
• Voltage - Clamping (Max) @ Ipp: 21.2V
• Current - Peak Pulse (10/1000µs): 28A minimum
• Power - Peak Pulse: 600W
• Mounting Type: Through Hole
• Package / Case: DO-15 or equivalent axial configuration
• Type: Zener TVS Diode
• Bidirectional Channels: 1

Substitute parts are grouped into two categories:

Category 1: Direct Electrical Equivalents (Active Status) Parts meeting all electrical specifications with active product status and current manufacturing availability.

Category 2: Functional Equivalents (Alternative Packaging) Parts meeting all electrical specifications but with different packaging or supplier configurations.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Recommended for Direct Replacement)

P6KE15CA-TP (Micro Commercial Co) and P6KE15CA-B (Littelfuse Inc.) are the preferred substitutes. Both maintain identical electrical specifications to the original P6KE15CA-T, support the same operating temperature range (-55°C ~ 175°C), and are in active production status with ROHS3 compliance. P6KE15CA-TP is available in Cut Tape packaging matching the original specification, while P6KE15CA-B is supplied in Bulk packaging.

Secondary Substitutes (Functionally Equivalent)

P6KE15CA (Fairchild Semiconductor) meets all electrical requirements with a marginally higher peak pulse current rating (29A vs. 28A) and operates across a slightly narrower temperature range (-50°C ~ 175°C). This part is suitable for applications where the upper temperature limit of -50°C is acceptable.

Alternative Packaging Option

P6KE15CAE3/TR13 (Microsemi Corporation) provides electrical equivalence in an axial package configuration. This part operates across an extended lower temperature range (-65°C ~ 150°C) and is suitable for applications requiring enhanced cold-temperature performance, provided the upper temperature limit of 150°C is compatible with the design.

Supplier Variants

P6KE15CA-AP and P6KE15CA-BP (Micro Commercial Co) are functionally equivalent to P6KE15CA-TP but supplied in Bulk packaging. These parts are suitable for high-volume production environments where bulk packaging is preferred.

Frequently Asked Questions (FAQ)

Q: Can P6KE15CA-TP be used as a direct replacement for P6KE15CA-T?

A: Yes. P6KE15CA-TP meets all electrical specifications of the original part, maintains identical voltage ratings (12.8V standoff, 21.2V clamping), peak pulse current (28A), and operating temperature range (-55°C ~ 175°C). Both are supplied in DO-15 packaging. The primary difference is manufacturer and product status (active vs. obsolete).

Q: What is the difference between P6KE15CA-TP, P6KE15CA-AP, and P6KE15CA-BP?

A: These three parts are electrically identical and manufactured by Micro Commercial Co. The suffix designates packaging configuration: TP indicates Cut Tape, AP indicates Bulk with Automotive grade, and BP indicates standard Bulk. Select based on procurement and assembly requirements.

Q: Is P6KE15CA (Fairchild) a suitable substitute?

A: Yes, with operational considerations. This part meets all voltage and current specifications but operates across a narrower temperature range (-50°C ~ 175°C vs. -55°C ~ 175°C). Verify that your application does not require operation below -50°C before selection.

Q: Can P6KE15CAE3/TR13 replace P6KE15CA-T in all applications?

A: P6KE15CAE3/TR13 provides electrical equivalence but differs in package configuration (Axial vs. DO-15) and operating temperature range (-65°C ~ 150°C). Use this part only if your PCB layout accommodates axial leads and your application does not require operation above 150°C.

Q: Are all substitute parts ROHS3 compliant?

A: P6KE15CA-TP, P6KE15CA-AP, P6KE15CA-BP, and P6KE15CA-B are ROHS3 compliant. P6KE15CA (Fairchild) and P6KE15CAE3/TR13 (Microsemi) compliance status is not specified in the provided data. Verify compliance requirements with your procurement specifications before final selection.

Q: What is the minimum peak pulse current requirement for substitution?

A: The original P6KE15CA-T specifies 28A peak pulse current. All recommended substitutes meet or exceed this specification (28A to 29A), ensuring adequate transient suppression performance.
