Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the P6KE12A-TP are qualified based on strict electrical and mechanical parameter alignment. The substitution criteria are:

• Voltage - Reverse Standoff (Typ): 10.2V
• Voltage - Breakdown (Min): 11.4V
• Voltage - Clamping (Max) @ Ipp: 16.7V
• Current - Peak Pulse (10/1000µs): 36A or higher
• Power - Peak Pulse: 600W
• Mounting Type: Through Hole
• Package / Case: DO-204AC or DO-15
• Type: Zener
• Unidirectional Channels: 1

Two substitute parts meet these criteria: P6KE12A (Fairchild Semiconductor) and P6KE12A-B (Littelfuse). Both maintain identical voltage specifications and equivalent current ratings within acceptable engineering tolerances.

Parameter Comparison

Engineering Selection Recommendations

All three parts—P6KE12A-TP, P6KE12A, and P6KE12A-B—are active production components with equivalent electrical performance for general-purpose TVS applications. Selection should be based on:

• Availability and inventory levels
• Packaging requirements (Cut Tape vs. Bulk)
• Compliance certifications (all three are RoHS3 compliant and REACH unaffected)
• Operating temperature minimum requirement (P6KE12A-TP and P6KE12A-B support -55°C; P6KE12A supports -50°C minimum)
• Supplier device package format (DO-15 or DO-204AC)

Frequently Asked Questions (FAQ)

Q: Can P6KE12A replace P6KE12A-TP in my circuit?

A: Yes. Both parts share identical voltage specifications (10.2V standoff, 16.7V clamping) and equivalent current ratings (36A vs. 37A peak pulse). The primary difference is the operating temperature minimum: P6KE12A operates from -50°C, while P6KE12A-TP operates from -55°C. Selection depends on your application's temperature requirements.

Q: What is the difference between P6KE12A-B and P6KE12A-TP?

A: Both parts are electrically equivalent with matching voltage and power specifications. P6KE12A-B is supplied in Bulk packaging by Littelfuse, while P6KE12A-TP is supplied in Cut Tape packaging by Micro Commercial Co. Both support the full -55°C to 175°C operating range. Packaging format and supplier availability are the primary differentiators.

Q: Are all three parts in the same package?

A: Yes. All three parts use DO-204AC (DO-15) axial through-hole packages, ensuring mechanical and electrical compatibility in PCB designs.

Q: Which part should I choose for new designs?

A: Selection should be based on current supplier relationships, inventory availability, and packaging preferences. All three parts meet identical electrical specifications and are suitable for new designs.

Q: Are there any compliance differences between these parts?

A: All three parts are RoHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Moisture sensitivity level is 1 (Unlimited) for P6KE12A-TP and P6KE12A-B. No compliance barriers exist for substitution.
