TPD4E002DRL2 Equivalent & Substitute Parts

Part Overview

The TPD4E002DRL2 is a transient voltage suppressor (TVS) diode manufactured by Texas Instruments, designed for general-purpose overvoltage protection in surface-mount applications. This unidirectional 4-channel TVS diode operates with a 3V reverse standoff voltage and 35W peak pulse power rating in an SOT-553 package. The part is currently active and ROHS3 compliant with unlimited moisture sensitivity rating.

Equivalent and substitute parts are identified when they share compatible electrical characteristics and mechanical specifications that allow direct functional replacement in circuit applications while maintaining design performance and reliability standards.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TPD4E002DRL2 are grouped based on the following critical parameters that determine functional compatibility:

Primary Substitution Criteria:

• Unidirectional channel configuration (4 channels required)
• Reverse standoff voltage range (3V nominal)
• Zener diode type classification
• Surface-mount packaging technology
• General-purpose application suitability
• ROHS3 compliance and active product status

Secondary Compatibility Factors:

• Voltage breakdown minimum specifications
• Peak pulse power rating capability
• Operating temperature range overlap
• Moisture sensitivity level (MSL 1 - Unlimited)

Substitutes are organized by package type (SOT-553 and SOT-665) and voltage characteristics. Parts with matching reverse standoff voltage (3V) and identical channel count represent direct functional equivalents. Parts with adjacent voltage ratings (3.3V, 4V, 4.3V, 5.5V) serve as alternatives where circuit design permits voltage tolerance adjustments.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active product status and ROHS3 compliance, ensuring regulatory alignment with the TPD4E002DRL2. Selection among substitutes depends on specific circuit voltage requirements and package constraints.

SOT-553 Package Substitutes (Direct Package Compatibility): NZQA5V6XV5T1G provides the closest electrical match with identical 3V reverse standoff voltage and SOT-553 packaging. This part offers enhanced peak pulse power (100W versus 35W) and extended operating temperature range (-55°C to 150°C), making it suitable for applications requiring higher transient energy absorption or wider temperature operation.

NZQA6V2XV5T1G and NZQA6V8XV5T1G maintain SOT-553 packaging with elevated reverse standoff voltages (4V and 4.3V respectively) and 100W peak pulse power ratings. These parts are applicable in circuits where higher voltage thresholds are acceptable.

SP1001-04XTG operates at 5.5V reverse standoff voltage in SOT-553 packaging with 2A peak pulse current rating, suitable for applications requiring higher voltage protection levels.

SOT-665 Package Substitutes (Package Variant): PESD3V3V4UW,115 provides 3.3V reverse standoff voltage in SOT-665 packaging with extended temperature range (-65°C to 150°C). This part accommodates applications requiring different package footprints while maintaining comparable voltage protection.

BZA962AVL,115 operates at 6.2V reverse standoff voltage in SOT-665 packaging with 6W peak pulse power, suitable for higher voltage protection requirements with alternative package geometry.

Frequently Asked Questions (FAQ)

Q: Can NZQA5V6XV5T1G directly replace TPD4E002DRL2? A: Yes, NZQA5V6XV5T1G is a direct functional equivalent. Both parts feature 3V reverse standoff voltage, 4-channel unidirectional configuration, and SOT-553 packaging. NZQA5V6XV5T1G provides superior peak pulse power (100W versus 35W) and extended operating temperature range, making it a compatible upgrade.

Q: What is the difference between SOT-553 and SOT-665 packages? A: SOT-553 and SOT-665 are distinct surface-mount package geometries with different pin configurations and footprints. Parts in SOT-665 packaging (PESD3V3V4UW,115 and BZA962AVL,115) require PCB layout modifications and cannot be directly substituted into SOT-553 footprints without redesign.

Q: Can I use NZQA6V2XV5T1G or NZQA6V8XV5T1G as substitutes? A: These parts are functionally compatible substitutes with higher reverse standoff voltages (4V and 4.3V respectively). They maintain SOT-553 packaging and 4-channel configuration. Use these substitutes only if circuit design permits operation at elevated voltage thresholds.

Q: What does reverse standoff voltage mean? A: Reverse standoff voltage is the maximum voltage a TVS diode can withstand in its off-state without conducting. The TPD4E002DRL2 operates at 3V standoff, meaning it remains non-conductive below this threshold and activates to clamp transients above the breakdown voltage.

Q: Are all substitutes ROHS3 compliant? A: Yes, all listed substitute parts are ROHS3 compliant and maintain active product status, ensuring regulatory compliance equivalent to the TPD4E002DRL2.

Q: Which substitute offers the highest peak pulse power? A: NZQA5V6XV5T1G, NZQA6V2XV5T1G, and NZQA6V8XV5T1G all provide 100W peak pulse power, compared to 35W for the TPD4E002DRL2. These parts accommodate applications requiring higher transient energy dissipation.
