Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the P6KE180A-B is determined by the following critical parameters:

• Voltage - Reverse Standoff (Typ): 154V
• Voltage - Breakdown (Min): 171V
• Voltage - Clamping (Max) @ Ipp: 246V
• Current - Peak Pulse (10/1000µs): 2.4A minimum
• Power - Peak Pulse: 600W
• Package / Case: DO-204AC or DO-15 (axial through-hole)
• Type: Zener, unidirectional configuration

All identified substitute parts maintain these electrical specifications and package compatibility, ensuring direct functional equivalence in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain active product status and are suitable for direct replacement in applications requiring 154V standoff voltage with 246V clamping characteristics.

P6KE180A-E3/54 (Vishay General Semiconductor) is available in the highest quantity (8200 units) and carries ROHS3 compliance certification. The TransZorb® series designation indicates manufacturer-specific qualification.

P6KE180A-TP (Micro Commercial Co) provides 2672 units in stock with ROHS3 compliance and is packaged in cut tape format.

P6KE180A (Fairchild Semiconductor) is available with 3832 units in stock. This variant specifies a peak pulse current of 2.5A, which exceeds the 2.4A requirement of the primary part, and operates across a minimum temperature of -50°C compared to -55°C for other variants. RoHS compliance status is not specified for this manufacturer variant.

Frequently Asked Questions (FAQ)

Q: Can P6KE180A-E3/54 replace P6KE180A-B in all applications?

A: Yes. Both parts share identical voltage ratings (154V standoff, 171V breakdown, 246V clamping), current specifications (2.4A peak pulse), power dissipation (600W), and operating temperature range (-55°C to 175°C). Package compatibility is confirmed for DO-204AC/DO-15 axial through-hole mounting.

Q: What is the difference between P6KE180A-TP and P6KE180A-B?

A: Electrical specifications are identical. The primary difference is packaging format: P6KE180A-TP is supplied in cut tape (CT) format, while P6KE180A-B packaging is not specified. Both are through-hole axial components compatible with DO-15/DO-204AC footprints.

Q: Is the Fairchild P6KE180A suitable as a substitute?

A: The Fairchild variant meets all critical voltage and power specifications. The peak pulse current rating of 2.5A exceeds the 2.4A requirement. The minimum operating temperature is -50°C versus -55°C for other variants. Selection depends on whether the -50°C lower limit is acceptable for the application. RoHS compliance status differs from other variants.

Q: Are all substitute parts through-hole components?

A: Yes. All identified substitutes are through-hole mounted devices in DO-15 or DO-204AC axial packages, maintaining mechanical compatibility with P6KE180A-B footprints.

Q: What compliance certifications apply to these parts?

A: P6KE180A-B, P6KE180A-E3/54, and P6KE180A-TP are ROHS3 compliant. All parts are REACH unaffected and classified under ECCN EAR99. Fairchild P6KE180A RoHS status is not specified in available documentation.
