Key Parameters

Substitute Part Grouping Explanation

Substitution of the P6SMBJ100 is determined by the following critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Reverse Standoff Voltage (Typ): 85.5V ± tolerance
• Breakdown Voltage (Min): 90V or higher
• Clamping Voltage (Max) @ Ipp: Must not exceed 143.85V significantly
• Peak Pulse Current (10/1000µs): 4.5A or compatible
• Power - Peak Pulse: 600W
• Unidirectional configuration (1 channel)

Mechanical Compatibility Criteria:

• Package / Case: DO-214AA (SMB)
• Mounting Type: Surface Mount
• Operating Temperature Range: -55°C minimum to 150°C maximum

Compliance Requirements:

• RoHS3 Compliant or equivalent
• Moisture Sensitivity Level: 1 (Unlimited)

Substitute parts must maintain electrical performance within the specified voltage and current parameters while preserving the DO-214AA surface-mount package form factor. All identified substitutes meet these criteria and are classified as active products, providing long-term availability compared to the obsolete P6SMBJ100.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts are classified as active products with current manufacturing status, ensuring long-term availability and supply chain stability compared to the obsolete P6SMBJ100. Selection among substitutes should be based on the following factors:

Primary Substitutes (Closest Electrical Match): P6SMB100A, SMBJP6KE100A-TP, SM6T100A-E3/52, SM6T100A-E3/5B, and TVP06B101A-G maintain clamping voltages of 137V, which is lower than the original 143.85V specification. These parts are suitable for applications where the reduced clamping voltage provides equivalent or improved protection margins.

Extended Temperature Range Options: SMBJP6KE100A-TP, SM6T100A-E3/52, SM6T100A-E3/5B, and SMBJ85AE3/TR13 support operating temperatures up to 175°C or -65°C minimum, providing enhanced thermal performance for demanding environments.

High Current Capability: SM6T100A features 22.5A peak pulse current (8/20µs pulse), offering increased transient suppression capacity for applications requiring higher current handling.

All substitute parts comply with ROHS3 or equivalent RoHS standards and maintain MSL 1 (Unlimited) moisture sensitivity ratings, ensuring compatibility with standard manufacturing and storage practices.

Frequently Asked Questions (FAQ)

Q: Can I directly replace P6SMBJ100 with any of the listed substitutes? A: Yes, all listed substitutes are electrically and mechanically compatible. They share the same DO-214AA (SMB) package, unidirectional configuration, 600W power rating, and operate within the required temperature range. All are RoHS3 compliant with MSL 1 ratings.

Q: What is the significance of the clamping voltage difference between P6SMBJ100 (143.85V) and most substitutes (137V)? A: The lower clamping voltage in substitutes (137V vs 143.85V) represents improved transient suppression performance. The device will clamp overvoltage transients at a lower threshold, providing better protection margins in most applications.

Q: Why does SM6T100A have a higher peak pulse current (22.5A) than the original part (4.5A)? A: SM6T100A uses a different pulse waveform specification (8/20µs vs 10/1000µs). While the peak current value differs, the power dissipation remains 600W. This part is suitable for applications requiring higher current transient suppression.

Q: Are there any temperature range considerations when selecting a substitute? A: The original P6SMBJ100 operates from -55°C to 150°C. Substitutes like SM6T100A-E3/52, SM6T100A-E3/5B, and SMBJ85AE3/TR13 extend the minimum operating temperature to -65°C, providing enhanced performance in cold environments. SMBJP6KE100A-TP extends the maximum to 175°C for high-temperature applications.

Q: Do all substitutes maintain the same package footprint? A: Yes, all substitutes use the DO-214AA (SMB) surface-mount package, ensuring identical PCB footprint and assembly compatibility with the original P6SMBJ100 design.

Q: What compliance certifications should I verify for my application? A: All listed substitutes are ROHS3 compliant or equivalent and maintain MSL 1 (Unlimited) moisture sensitivity ratings. Verify REACH compliance status with your supplier if required for your specific market or application.
