Key Parameters

Substitute Part Grouping Explanation

Substitution of the BZW04-15-E3/54 is determined by the following critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Voltage - Reverse Standoff (Typ): 15.3V
• Voltage - Breakdown (Min): 17.1V
• Voltage - Clamping (Max) @ Ipp: 25.2V
• Type: Zener, Unidirectional
• Applications: General Purpose

Mechanical Compatibility Criteria:

• Mounting Type: Through Hole
• Package / Case: DO-204AL (DO-41) or equivalent axial through-hole packages

The P6KE18A from Fairchild Semiconductor qualifies as a substitute part because it maintains identical voltage specifications (15.3V standoff, 17.1V breakdown, 25.2V clamping) and operates within the same application category. The substitute part is compatible with through-hole mounting and uses a DO-204AC (DO-15) axial package, which is mechanically compatible with the original DO-204AL footprint.

Parameter Comparison

Engineering Selection Recommendations

Both the BZW04-15-E3/54 and P6KE18A are active production components with established compliance certifications. The BZW04-15-E3/54 is ROHS3 compliant and carries REACH Unaffected status. The P6KE18A maintains identical voltage performance specifications, making it electrically interchangeable for applications requiring 15.3V standoff protection with 25.2V clamping.

The P6KE18A offers higher peak pulse current (25A versus 16A) and greater peak pulse power (600W versus 400W), providing enhanced transient suppression capability. Both devices use axial through-hole packages compatible with standard PCB layouts. Selection between these parts should be based on availability, lead time, and specific application current requirements.

Frequently Asked Questions (FAQ)

Q: Can the P6KE18A directly replace the BZW04-15-E3/54?

A: Yes. Both devices maintain identical voltage specifications (15.3V standoff, 17.1V breakdown, 25.2V clamping) and are unidirectional zener TVS diodes designed for general-purpose transient suppression. The axial through-hole packages (DO-204AL and DO-204AC) are mechanically compatible on standard PCB footprints.

Q: What are the key differences between these substitute parts?

A: The P6KE18A provides higher peak pulse current (25A versus 16A) and greater peak pulse power (600W versus 400W). The operating temperature range differs slightly: BZW04-15-E3/54 operates from -55°C to 175°C, while P6KE18A operates from -50°C to 175°C.

Q: Are both parts suitable for the same applications?

A: Yes. Both parts are classified for general-purpose transient voltage suppression. The identical voltage specifications ensure equivalent protection performance in circuits designed for 15.3V standoff voltage with 25.2V clamping.

Q: What packaging considerations apply to substitution?

A: The BZW04-15-E3/54 uses DO-204AL (DO-41) packaging, while the P6KE18A uses DO-204AC (DO-15) packaging. Both are axial through-hole packages with compatible lead spacing and footprints suitable for standard PCB designs.

Q: Are there compliance or certification differences?

A: The BZW04-15-E3/54 is explicitly ROHS3 compliant with REACH Unaffected status. Both parts carry EAR99 ECCN classification and HTSUS code 8541.10.0080, indicating equivalent regulatory treatment for export and trade purposes.
