Substitute Part Grouping Explanation

Substitution of the P6KE36CA-T is determined by strict equivalence across the following electrical and mechanical parameters:

Voltage - Reverse Standoff (Typ): 30.8V
Voltage - Breakdown (Min): 34.2V
Voltage - Clamping (Max) @ Ipp: 49.9V
Current - Peak Pulse (10/1000µs): 12A (±0.2A tolerance acceptable)
Power - Peak Pulse: 600W
Mounting Type: Through Hole
Package / Case: DO-15 or DO-204AC (Axial)
Type: Zener, Bidirectional, Single Channel

Substitute parts are grouped into two categories: direct manufacturer equivalents from active suppliers and manufacturer-recommended alternatives. All listed substitutes maintain identical electrical performance specifications and are compatible with the original application requirements.

Frequently Asked Questions (FAQ)

Q: Can P6KE36CA-T be directly replaced with P6KE36CA?

A: Yes. P6KE36CA from Taiwan Semiconductor Corporation provides direct electrical equivalence with identical voltage ratings (30.8V standoff, 49.9V clamping), current handling (12A peak pulse), and power dissipation (600W). Both are ROHS3 compliant and suitable for the same applications.

Q: What is the difference between P6KE36CA-TP, P6KE36CA-AP, and P6KE36CA-BP?

A: These are packaging variants of the same electrical component from Micro Commercial Co. The suffix indicates packaging format: -TP is Cut Tape, -AP and -BP are Bulk packaging. All three maintain identical electrical specifications and are interchangeable from a functional standpoint.

Q: Is P6KE36CA-B compatible with the original P6KE36CA-T?

A: Yes. P6KE36CA-B from Littelfuse Inc. is electrically equivalent with matching voltage and power specifications. The peak pulse current is specified at 12.2A versus 12A, providing additional safety margin. The package is DO-204AC (equivalent to DO-15), and operating temperature range is -55°C ~ 175°C.

Q: Why is the operating temperature range not specified for P6KE36CA from Taiwan Semiconductor Corporation?

A: The operating temperature specification is not provided in the available data. For applications with strict temperature requirements, P6KE36CA-B (Littelfuse) or P6KE36CA-TP (Micro Commercial Co) are recommended, as both specify -55°C ~ 175°C operating range.

Q: Can the axial package variant P6KE36CAE3/TR13 be used in place of DO-15 packages?

A: P6KE36CAE3/TR13 is electrically equivalent but uses axial through-hole packaging instead of DO-15. Physical board layout compatibility must be verified. The operating temperature range is -65°C ~ 150°C, which differs from the original specification.

Q: Are all substitute parts ROHS3 compliant?

A: All listed substitutes carry ROHS3 compliance certification. Compliance status is confirmed for P6KE36CA (Taiwan Semiconductor), P6KE36CA-TP, P6KE36CA-B (Littelfuse), and P6KE36CAE3/TR13 (Microsemi). Compliance information for P6KE36CA-AP and P6KE36CA-BP is not specified in available data.
