DLP3V3DTZ-7 Equivalent & Substitute Parts

Part Overview

The DLP3V3DTZ-7 is a transient voltage suppressor (TVS) diode manufactured by Diodes Incorporated, designed for surface mount applications in the SOT-23-3 package. This component provides bidirectional ESD and transient protection with a 3.3V reverse standoff voltage and clamping voltages of 9.3V and 9.666V. The part is classified as obsolete, making identification of suitable substitute components essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DLP3V3DTZ-7 is determined by the following critical parameters:

• Reverse standoff voltage: 3.3V (Max)
• Bidirectional protection capability: 2 unidirectional channels
• Package compatibility: SOT-23-3 / TO-236-3 / SC-59
• Surface mount configuration
• Automotive grade qualification
• Operating temperature range: minimum -55°C to 150°C
• RoHS3 compliance

The PESD3V3S2UT,215 from Nexperia USA Inc. meets these substitution criteria. Both devices maintain the 3.3V reverse standoff voltage specification, support bidirectional protection through dual channels, utilize compatible SOT-23-3 packaging, and carry automotive-grade qualification with AEC-Q100 certification. Both components are RoHS3 compliant and operate across overlapping temperature ranges suitable for automotive applications.

Parameter Comparison

Engineering Selection Recommendations

The PESD3V3S2UT,215 is a suitable substitute for the obsolete DLP3V3DTZ-7 based on the following factors:

Both components maintain identical reverse standoff voltage specifications (3.3V Max) and bidirectional channel configuration (2 channels), ensuring functional equivalence in circuit protection topology. Package compatibility is confirmed across TO-236-3, SC-59, and SOT-23-3 designations, allowing direct board-level substitution without layout modifications.

The substitute part offers enhanced performance characteristics: higher peak pulse current rating (18A vs. 15A at 8/20µs), increased peak pulse power dissipation (330W vs. 145W), and extended lower operating temperature limit (-65°C vs. -55°C). These improvements provide additional design margin without compromising the primary protection function.

Both devices carry automotive-grade qualification with RoHS3 compliance and MSL Level 1 moisture sensitivity, meeting the same regulatory and environmental requirements. The substitute part holds active product status with established supply chain availability, addressing the obsolescence of the original component.

Frequently Asked Questions (FAQ)

Q: Can the PESD3V3S2UT,215 be used as a direct replacement for the DLP3V3DTZ-7?

A: Yes. Both devices share the same 3.3V reverse standoff voltage, bidirectional protection topology (2 channels), and SOT-23-3 package configuration. No circuit modifications or board redesign are required for substitution.

Q: What are the key differences between these two TVS diodes?

A: The primary differences are clamping voltage (9.3V/9.666V vs. 20V), peak pulse current (15A vs. 18A at 8/20µs), and peak pulse power dissipation (145W vs. 330W). The substitute part provides higher performance ratings. The substitute also operates to -65°C compared to -55°C for the original part.

Q: Are both parts qualified for automotive applications?

A: Yes. Both components carry automotive-grade qualification. The original part holds AEC-Q101 certification, while the substitute carries AEC-Q100 certification. Both meet automotive reliability and quality standards.

Q: Is the package footprint identical between these parts?

A: Yes. Both components use the SOT-23-3 package (also designated TO-236-3 or SC-59), ensuring identical PCB footprint and mounting compatibility.

Q: What is the moisture sensitivity level for the substitute part?

A: The PESD3V3S2UT,215 carries MSL Level 1 (Unlimited), matching the original DLP3V3DTZ-7. No special moisture control measures are required during storage or handling.

Q: Does the substitute part have better availability than the original?

A: Yes. The DLP3V3DTZ-7 is classified as obsolete, while the PESD3V3S2UT,215 maintains active product status with established supply chain distribution.
