DLPT05-7-F Equivalent & Substitute Parts

Part Overview

The DLPT05-7-F is a Transient Voltage Suppressor (TVS) diode manufactured by Diodes Incorporated, designed for general-purpose overvoltage protection in surface-mount applications. This unidirectional steering diode operates with a 5V reverse standoff voltage and provides 9.8V clamping at peak pulse current. The part is classified as Last Time Buy, indicating end-of-life status. Equivalent and substitute parts are necessary to ensure design continuity and maintain supply chain flexibility for new production runs and legacy system support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DLPT05-7-F is determined by the following critical electrical and mechanical parameters:

Primary Substitution Criteria:

• Reverse standoff voltage: 5V
• Breakdown voltage minimum: 6V
• Package compatibility: SOT-23-3 (TO-236-3, SC-59)
• Unidirectional channel configuration: 1 channel
• Surface mount mounting type
• RoHS3 compliance
• Moisture sensitivity level: 1

Secondary Compatibility Factors:

• Clamping voltage at peak pulse current
• Peak pulse current rating
• Peak pulse power dissipation
• Operating temperature range
• Capacitance characteristics

Substitute parts must maintain the same reverse standoff voltage (5V) and package form factor (SOT-23-3) to ensure direct replacement capability. Variations in clamping voltage, peak pulse current, and power dissipation are acceptable provided the substitute meets or exceeds the application requirements for overvoltage protection.

Engineering Selection Recommendations

DLPT05A-7 (Diodes Incorporated)

This is the manufacturer-recommended substitute from Diodes Incorporated. It maintains identical electrical specifications to the DLPT05-7-F, including 9.8V clamping voltage, 17A peak pulse current, and 300W peak pulse power. The DLPT05A-7 is in Active product status, ensuring long-term availability. It carries AEC-Q101 automotive qualification, providing enhanced reliability for mission-critical applications. This part is the preferred choice for direct replacement in existing designs.

SL05T1G (onsemi)

This substitute offers compatibility with the same 5V reverse standoff voltage and SOT-23-3 package. The SL05T1G provides 11V clamping voltage and 5A peak pulse current, with 300W peak pulse power dissipation. It is in Active product status and carries AEC-Q101 automotive qualification. The higher clamping voltage (11V vs. 9.8V) may be acceptable in applications where the protection threshold is not critical. This part is suitable for designs with less stringent clamping requirements.

PESD5V0U1UT,215 (Nexperia USA Inc.)

This substitute maintains the 5V reverse standoff voltage and SOT-23-3 package compatibility. However, it exhibits significantly different electrical characteristics: 21V clamping voltage, 5A peak pulse current, and 80W peak pulse power. The PESD5V0U1UT,215 is in Active product status. The substantially higher clamping voltage and lower power dissipation make this part suitable only for applications where higher voltage protection thresholds are acceptable and peak pulse power requirements are lower than the original design.

Frequently Asked Questions (FAQ)

Q: Can DLPT05A-7 be used as a direct replacement for DLPT05-7-F?

A: Yes. The DLPT05A-7 is the manufacturer-recommended substitute with identical electrical specifications, including 5V reverse standoff voltage, 9.8V clamping voltage, 17A peak pulse current, and 300W peak pulse power. Both parts use the SOT-23-3 package and operate across the same temperature range. The DLPT05A-7 is in Active product status, ensuring continued availability.

Q: What are the key differences between SL05T1G and DLPT05-7-F?

A: Both parts share the same 5V reverse standoff voltage and SOT-23-3 package. The primary difference is the clamping voltage: SL05T1G clamps at 11V compared to 9.8V for DLPT05-7-F. Additionally, SL05T1G has a lower peak pulse current rating (5A vs. 17A). The SL05T1G is suitable for applications where the higher clamping voltage is acceptable and peak pulse current requirements do not exceed 5A.

Q: Is PESD5V0U1UT,215 a suitable substitute?

A: PESD5V0U1UT,215 maintains the 5V reverse standoff voltage and SOT-23-3 package compatibility. However, it has a significantly higher clamping voltage (21V) and lower peak pulse current (5A) and power dissipation (80W) compared to DLPT05-7-F. This part is suitable only for applications where higher clamping voltage thresholds are acceptable and peak pulse power requirements are lower than the original design specifications.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. DLPT05A-7, PESD5V0U1UT,215, and SL05T1G are all ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), matching the compliance profile of DLPT05-7-F.

Q: Which substitute offers automotive qualification?

A: Both DLPT05A-7 and SL05T1G carry AEC-Q101 automotive qualification, providing enhanced reliability for automotive and mission-critical applications. PESD5V0U1UT,215 does not have automotive qualification.

Q: Can these parts be used interchangeably in the same PCB layout?

A: Yes. All substitute parts use the SOT-23-3 package (TO-236-3, SC-59), enabling direct PCB footprint compatibility. However, electrical performance differences must be evaluated for each application to ensure the substitute meets protection requirements.
