Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for P6KE16A-T is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff (Typ): 13.6V
• Voltage - Breakdown (Min): 15.2V
• Voltage - Clamping (Max) @ Ipp: 22.5V
• Current - Peak Pulse (10/1000µs): 27A (±0.1A tolerance acceptable)
• Power - Peak Pulse: 600W
• Type: Zener, Unidirectional
• Mounting Type: Through Hole
• Package / Case: DO-204AC or DO-15 compatible

All substitute parts listed below meet these electrical specifications. Packaging variants (Bulk, Strip, Cut Tape) and manufacturer differences do not affect electrical compatibility. Operating temperature ranges and compliance certifications may vary; these differences are noted in the parameter comparison table.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain electrical equivalence to P6KE16A-T across voltage clamping, breakdown, and peak pulse current specifications. Selection among active alternatives should be based on the following criteria:

Direct Electrical Equivalents (27A Peak Pulse Current): P6KE16A-AP, P6KE16A-BP, P6KE16A-TP, P6KE16AE3/TR13, and TP6KE16A provide exact or near-exact peak pulse current matching (27.0–27.1A). These parts are recommended for applications requiring strict adherence to the original P6KE16A-T specifications.

Minor Current Variance: P6KE16A (Diotec Semiconductor) specifies 28A peak pulse current, representing a 3.7% increase over the original 27A specification. This part remains electrically compatible for general-purpose overvoltage protection but should be evaluated if circuit design margins are critical.

Operating Temperature Considerations: P6KE16AE3/TR13 (Microsemi Corporation) specifies a maximum junction temperature of 150°C, compared to 175°C for other alternatives. Applications operating near upper thermal limits should prioritize parts with -55 to 175°C ratings.

Packaging and Compliance: All substitute parts are RoHS3 compliant. P6KE16A-AP and P6KE16A-BP carry automotive-grade qualification. TP6KE16A includes AEC-Q101 qualification, suitable for automotive applications requiring formal qualification documentation.

Frequently Asked Questions (FAQ)

Q: Can P6KE16A-AP, P6KE16A-BP, and P6KE16A-TP be used interchangeably with P6KE16A-T?

A: Yes. All three parts are manufactured by Micro Commercial Co and maintain identical electrical specifications (13.6V standoff, 15.2V breakdown, 22.5V clamping, 27A peak pulse current, 600W peak power). Differences in packaging (Bulk, Cut Tape) do not affect electrical performance. Direct substitution is supported.

Q: What is the difference between P6KE16A-B and TP6KE16A?

A: Both are manufactured by Littelfuse Inc. and share identical electrical specifications (13.6V standoff, 15.2V breakdown, 22.5V clamping, 27.1A peak pulse current). TP6KE16A includes AEC-Q101 automotive qualification and is supplied in Cut Tape packaging, while P6KE16A-B is supplied in Bulk packaging. Selection depends on packaging requirements and automotive qualification needs.

Q: Is P6KE16A (Diotec Semiconductor) a suitable substitute despite the 28A peak pulse current specification?

A: P6KE16A maintains all critical voltage parameters (13.6V standoff, 15.2V breakdown, 22.5V clamping) and exceeds the original 27A specification by 3.7%. For general-purpose overvoltage protection, this part is electrically compatible. Applications with tight design margins or current-limited circuits should confirm that the higher current rating does not introduce unintended behavior.

Q: Can P6KE16AE3/TR13 be used as a direct replacement?

A: P6KE16AE3/TR13 maintains all critical electrical specifications but is packaged in T-18 Axial configuration rather than DO-15. Mechanical compatibility with existing PCB layouts must be verified. The maximum operating temperature is 150°C versus 175°C for other alternatives; applications operating near upper thermal limits should be evaluated accordingly.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed are RoHS3 compliant. P6KE16A-AP and P6KE16A-BP carry automotive-grade designation. TP6KE16A includes AEC-Q101 qualification for automotive applications.

Q: What packaging options are available for P6KE16A-T substitutes?

A: Substitute parts are available in Bulk, Strip, and Cut Tape (CT) packaging formats. Packaging selection does not affect electrical performance and is determined by procurement and assembly requirements. DO-15 and DO-204AC package designations are equivalent and mechanically compatible.
