TPD6V8LP-7B Equivalent & Substitute Parts

Part Overview

The TPD6V8LP-7B is a unidirectional transient voltage suppressor (TVS) diode manufactured by Diodes Incorporated, designed for surface mount applications in the 0402 (1006 Metric) package. This component provides transient overvoltage protection with a 5V reverse standoff voltage and 19V maximum clamping voltage at peak pulse current.

The TPD6V8LP-7B is classified as Obsolete, which necessitates identification of equivalent substitute components for ongoing design support and procurement. The part remains available in inventory (35,300 pieces), but its obsolete status requires engineers to evaluate functionally equivalent alternatives for new designs and long-term supply chain planning.

Substitute Part Grouping Explanation

Substitution of the TPD6V8LP-7B is determined by strict equivalence across the following critical electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Voltage - Reverse Standoff (Typ): 5V
• Voltage - Breakdown (Min): 6.4V
• Voltage - Clamping (Max) @ Ipp: 19V
• Current - Peak Pulse (10/1000µs): 4.5A (8/20µs)
• Power - Peak Pulse: 85W
• Capacitance @ Frequency: 65pF @ 1MHz
• Operating Temperature Range: -65°C to 150°C (TJ)

Mechanical Equivalence Criteria:

• Package / Case: 0402 (1006 Metric)
• Mounting Type: Surface Mount
• Unidirectional Channels: 1

Compliance Equivalence Criteria:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• REACH Status: REACH Unaffected

The primary substitute identified is TPD6V8LP-7, which maintains identical electrical specifications and mechanical packaging while differing only in product status (Last Time Buy versus Obsolete) and packaging format (Tape & Reel versus unspecified).

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: TPD6V8LP-7

The TPD6V8LP-7 is the direct functional equivalent of the TPD6V8LP-7B. Both components are manufactured by Diodes Incorporated and share identical electrical specifications, mechanical packaging, and compliance certifications. The TPD6V8LP-7 is classified as Last Time Buy, indicating extended availability compared to the Obsolete status of the TPD6V8LP-7B.

Selection of TPD6V8LP-7 is appropriate for:

• Direct replacement in existing designs
• New designs requiring 5V reverse standoff TVS protection
• Applications requiring ROHS3 compliance and unlimited moisture sensitivity rating
• Surface mount assembly processes compatible with 0402 (1006 Metric) packages

The primary distinction between these parts is packaging format: TPD6V8LP-7 is supplied in Tape & Reel format, which is standard for automated assembly operations. Procurement planning should account for the Last Time Buy status of TPD6V8LP-7, as this indicates a defined end-of-life timeline.

Both parts maintain identical performance across all critical electrical parameters, including voltage ratings, peak pulse current, power dissipation, and capacitance characteristics. No functional or performance differences exist between these components.

Frequently Asked Questions (FAQ)

Q: Why is the TPD6V8LP-7B classified as Obsolete?

A: The TPD6V8LP-7B has reached end-of-life status with Diodes Incorporated. The TPD6V8LP-7 serves as the active replacement part and is available in Last Time Buy status, providing a defined procurement window for transition planning.

Q: Are TPD6V8LP-7B and TPD6V8LP-7 electrically identical?

A: Yes. Both parts maintain identical electrical specifications across all parameters: 5V reverse standoff voltage, 6.4V minimum breakdown voltage, 19V maximum clamping voltage, 4.5A peak pulse current, 85W peak pulse power, and 65pF capacitance at 1MHz. Operating temperature range is identical at -65°C to 150°C (TJ).

Q: What is the difference between TPD6V8LP-7B and TPD6V8LP-7?

A: The primary differences are product status and packaging format. TPD6V8LP-7B is Obsolete with unspecified packaging, while TPD6V8LP-7 is Last Time Buy supplied in Tape & Reel format. All electrical and mechanical specifications are identical.

Q: Can TPD6V8LP-7 be used as a direct replacement in existing PCB designs?

A: Yes. The TPD6V8LP-7 is mechanically and electrically compatible with the TPD6V8LP-7B. Both components use the same 0402 (1006 Metric) surface mount package (X1-DFN1006-2) and require no design modifications for substitution.

Q: Are there compliance differences between these parts?

A: No. Both TPD6V8LP-7B and TPD6V8LP-7 are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. Compliance certifications are identical.

Q: What is the inventory status of these parts?

A: TPD6V8LP-7B has 35,300 pieces in stock (Obsolete status). TPD6V8LP-7 has 62,400 pieces in stock (Last Time Buy status). The higher inventory of TPD6V8LP-7 reflects its active replacement role.

Q: Is the Tape & Reel packaging of TPD6V8LP-7 compatible with automated assembly?

A: Yes. Tape & Reel packaging is the standard format for automated surface mount assembly operations. This packaging format is compatible with standard pick-and-place equipment used in manufacturing environments.

Q: What peak pulse current does this TVS diode support?

A: Both TPD6V8LP-7B and TPD6V8LP-7 support 4.5A peak pulse current at 8/20µs pulse width, with 85W peak pulse power dissipation capability.

Q: What is the operating temperature range for these components?

A: Both parts operate across -65°C to 150°C junction temperature (TJ) range, suitable for industrial and extended temperature applications.
