DLPT05-7 Equivalent & Substitute Parts

Part Overview

The DLPT05-7 is a transient voltage suppressor (TVS) diode manufactured by Diodes Incorporated, designed for general-purpose overvoltage protection in surface-mount applications. This component features a 5V reverse standoff voltage with a 9.8V maximum clamping voltage and 17A peak pulse current capability in an SOT-23-3 package. The DLPT05-7 is currently discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives that maintain electrical and mechanical compatibility for ongoing production and repair applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DLPT05-7 are identified based on strict electrical and mechanical compatibility criteria. The primary substitution parameters are:

• Reverse standoff voltage: 5V nominal
• Package compatibility: SOT-23-3 surface-mount form factor
• Operating temperature range: minimum -55°C to 150°C coverage
• Peak pulse current capability: 17A at 8/20µs waveform
• Maximum clamping voltage: 9.8V threshold

The DLPT05-7-F is a direct manufacturer equivalent from Diodes Incorporated, differing only in packaging format (Tape & Reel) and product status (Last Time Buy vs. Discontinued). This part maintains identical electrical specifications and package geometry.

The Nexperia parts (PESD5V0S2UAT,215 and PESD5V0U1UT,215) are manufacturer-recommended alternatives that share the 5V reverse standoff voltage and SOT-23-3 package compatibility. However, these parts exhibit different electrical characteristics in clamping voltage, peak pulse current, and channel configuration, requiring application-level verification before substitution.

Parameter Comparison

Engineering Selection Recommendations

For applications requiring direct electrical and mechanical equivalence, the DLPT05-7-F is the primary substitute. This part maintains identical electrical specifications and package geometry while offering improved product status (Last Time Buy) and ROHS3 compliance compared to the discontinued DLPT05-7.

The Nexperia alternatives (PESD5V0S2UAT,215 and PESD5V0U1UT,215) are suitable only for applications where the higher clamping voltages (20V and 21V respectively) and reduced peak pulse current capabilities do not compromise circuit protection requirements. These parts offer the advantage of active product status and ROHS3 compliance. The PESD5V0S2UAT,215 provides dual-channel protection, while the PESD5V0U1UT,215 offers significantly lower capacitance (0.6pF) for high-frequency sensitive applications.

Selection should prioritize DLPT05-7-F for direct replacement in existing designs. Nexperia alternatives require circuit-level validation to confirm compatibility with the specific overvoltage protection thresholds and current handling requirements of the application.

Frequently Asked Questions (FAQ)

Q: Can DLPT05-7-F be used as a direct replacement for DLPT05-7?

A: Yes. The DLPT05-7-F is electrically and mechanically identical to the DLPT05-7, differing only in packaging format (Tape & Reel) and product lifecycle status. Both parts feature 5V reverse standoff voltage, 9.8V maximum clamping voltage, 17A peak pulse current, and SOT-23-3 package geometry.

Q: What are the key differences between DLPT05-7 and the Nexperia alternatives?

A: The Nexperia parts differ in clamping voltage (20V and 21V vs. 9.8V), peak pulse current (15A and 5A vs. 17A), and capacitance characteristics. The PESD5V0S2UAT,215 provides dual-channel protection, while PESD5V0U1UT,215 is single-channel. These differences require application-specific validation before substitution.

Q: Are all substitute parts compatible with the SOT-23-3 package footprint?

A: Yes. All listed substitute parts use the SOT-23-3 (TO-236-3, SC-59) surface-mount package, ensuring mechanical and PCB-level compatibility with the original DLPT05-7 design.

Q: Which substitute part offers the best compliance status?

A: All substitute parts (DLPT05-7-F, PESD5V0S2UAT,215, and PESD5V0U1UT,215) are ROHS3 compliant. The DLPT05-7 original part is RoHS non-compliant. For new designs or compliance-driven applications, any of the substitute parts satisfy current regulatory requirements.

Q: What is the operating temperature range for each substitute?

A: DLPT05-7-F maintains the original range of -55°C to 150°C (junction temperature). The Nexperia parts extend the lower limit to -65°C with ambient temperature measurement, providing broader thermal coverage for demanding environments.

Q: Can PESD5V0U1UT,215 replace DLPT05-7 in high-frequency applications?

A: The PESD5V0U1UT,215 offers significantly lower capacitance (0.6pF vs. 1.9pF), making it suitable for high-frequency sensitive circuits. However, its reduced peak pulse current (5A vs. 17A) and higher clamping voltage (21V vs. 9.8V) require verification against circuit protection requirements before substitution.
