Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the P6KE36A-TP are classified based on electrical and mechanical parameter alignment within the TVS diode category. The primary substitution criteria are:

Direct Electrical Equivalents: Parts with identical or functionally equivalent reverse standoff voltage (30.8V), breakdown voltage (34.2V minimum), clamping voltage (49.9V), and peak pulse current rating (12A or higher). These parts maintain the same protection characteristics and circuit performance.

Package Compatibility: All substitute parts must use DO-15 or DO-204AC through-hole axial packaging to ensure mechanical and electrical compatibility with existing PCB layouts and footprints.

Compliance & Status: Substitute parts must maintain Active product status and RoHS3 compliance to meet modern manufacturing and environmental standards.

Operating Temperature Range: Substitute parts must support the operating temperature range of -55°C to 175°C or equivalent thermal specifications.

The following parts meet these substitution criteria:

• P6KE36A (Fairchild Semiconductor) – Direct electrical equivalent with identical voltage and current ratings
• P6KE36A-E3/54 (Vishay General Semiconductor) – Direct electrical equivalent with TransZorb® series designation
• BZW06-31RL (STMicroelectronics) – Similar electrical characteristics with higher peak pulse current capability (62A at 8/20µs pulse)

Parameter Comparison

Engineering Selection Recommendations

P6KE36A (Fairchild Semiconductor): This part is a direct electrical equivalent with a marginally higher peak pulse current rating (12.6A vs. 12A). It maintains identical voltage specifications and 600W peak pulse power rating. The operating temperature range is -50°C to 175°C, which covers the primary operating window of the main part. This substitute is suitable for direct replacement in applications where the lower temperature limit of -50°C is acceptable. RoHS3 compliance status is not specified in the provided data.

P6KE36A-E3/54 (Vishay General Semiconductor): This part provides direct electrical equivalence with identical voltage and current ratings (12A peak pulse). It maintains the full operating temperature range of -55°C to 175°C and is RoHS3 compliant. The TransZorb® series designation indicates Vishay's TVS product line. This substitute is fully compatible for direct replacement in all applications requiring the P6KE36A-TP.

BZW06-31RL (STMicroelectronics): This part shares the same reverse standoff voltage (30.8V) and breakdown voltage (34.2V) but features a higher clamping voltage (64.3V) and significantly higher peak pulse current capability (62A at 8/20µs pulse). The BZW06 series is part of STMicroelectronics' TRANSIL™ product line. This substitute is suitable for applications requiring enhanced transient suppression capability or higher current handling, though the higher clamping voltage may affect circuit protection thresholds. Operating temperature range is not specified in the provided data. RoHS3 compliance is confirmed.

Frequently Asked Questions (FAQ)

Q: Can I use P6KE36A (Fairchild) as a direct replacement for P6KE36A-TP?

A: Yes. The P6KE36A from Fairchild Semiconductor provides direct electrical equivalence with identical reverse standoff voltage (30.8V), breakdown voltage (34.2V), and clamping voltage (49.9V). The peak pulse current is slightly higher at 12.6A versus 12A. The operating temperature range is -50°C to 175°C. Verify that the -50°C lower temperature limit meets your application requirements.

Q: What is the difference between P6KE36A-E3/54 and the main part P6KE36A-TP?

A: Both parts are electrically identical with matching voltage ratings (30.8V standoff, 49.9V clamp) and current ratings (12A peak pulse). The P6KE36A-E3/54 is manufactured by Vishay under the TransZorb® series and maintains the full operating temperature range of -55°C to 175°C. The primary difference is manufacturer and product line designation. Both are RoHS3 compliant and Active status.

Q: When should I use BZW06-31RL instead of the original part?

A: The BZW06-31RL should be selected when your application requires higher transient current handling (62A at 8/20µs pulse versus 12A at 10/1000µs) or enhanced voltage suppression capability. However, the higher clamping voltage (64.3V versus 49.9V) will result in higher residual voltage across the protected circuit during transient events. Use this substitute only if your circuit design specifically requires these enhanced characteristics.

Q: Are all substitute parts available in the same DO-15 package?

A: Yes. All substitute parts listed are available in DO-15 (DO-204AC) through-hole axial packaging, ensuring mechanical compatibility with existing PCB layouts and footprints designed for the P6KE36A-TP.

Q: Do all substitute parts meet RoHS3 compliance?

A: P6KE36A-E3/54 and BZW06-31RL are confirmed RoHS3 compliant. RoHS3 compliance status for P6KE36A (Fairchild) is not specified in the provided data. Verify compliance documentation with the supplier if RoHS3 certification is required for your application.

Q: What is the difference between the 10/1000µs and 8/20µs pulse specifications?

A: These represent different test pulse waveforms used to characterize TVS diode performance. The 10/1000µs pulse is a standard test condition for most TVS diodes, while the 8/20µs pulse is commonly used for surge protection applications. The BZW06-31RL specifies 62A at the 8/20µs pulse, which represents a different transient profile than the 12A at 10/1000µs specified for the main part and other substitutes.
