DLP05LC-7 Equivalent & Substitute Parts

Part Overview

The DLP05LC-7 is a unidirectional 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 an 11V maximum clamping voltage and 17A peak pulse current capability in an SOT-23-3 package. The part is currently discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives that maintain electrical and mechanical compatibility for new designs or production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DLP05LC-7 is determined by the following critical parameters:

• Reverse Standoff Voltage: Must be 5V (typical)
• Clamping Voltage: Maximum 11V at peak pulse current
• Peak Pulse Current: Minimum 17A at 8/20µs waveform
• Power Dissipation: Minimum 300W peak pulse rating
• Package: SOT-23-3 surface mount configuration
• Channel Configuration: Unidirectional (single channel)

Substitute parts are grouped into two categories based on electrical performance alignment:

Category A - Direct Electrical Match: Parts meeting all key electrical parameters (5V standoff, 11V clamping, 17A peak current, 300W power rating) with identical channel configuration.

Category B - Functional Equivalent with Parameter Variance: Parts maintaining 5V standoff voltage and SOT-23-3 package but with acceptable deviations in clamping voltage or peak current that do not compromise circuit protection function.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: DLP05LC-7-F

The DLP05LC-7-F is the direct equivalent from Diodes Incorporated, matching all electrical specifications of the discontinued DLP05LC-7. This part maintains identical voltage ratings (5V standoff, 11V clamping), peak pulse current (17A), power dissipation (300W), and capacitance characteristics. The DLP05LC-7-F is currently in active production status with ROHS3 compliance, making it the preferred choice for design continuity and supply chain stability. Packaging is available in Cut Tape and Digi-Reel formats.

Secondary Substitute: SM05T1G

The SM05T1G from onsemi provides electrical performance closely aligned with the original specification. It maintains the 5V reverse standoff voltage, 17A peak pulse current, and 300W power rating. The clamping voltage is 9.8V, which is lower than the 11V specification but remains within acceptable protection margins for general-purpose applications. This part features a dual-channel configuration (2 channels) in the same SOT-23-3 package, offering additional circuit protection capability. ROHS3 compliance and active production status support long-term availability.

Tertiary Substitute: PESD5V0U1UT,215

The PESD5V0U1UT,215 from Nexperia USA Inc. maintains the 5V reverse standoff voltage and SOT-23-3 package compatibility. However, this part exhibits reduced peak pulse current (5A versus 17A) and lower power dissipation (80W versus 300W), with a higher clamping voltage of 21V. This substitute is suitable only for applications with lower transient current requirements and should be evaluated against specific circuit protection thresholds. ROHS3 compliance and active production status are confirmed.

Frequently Asked Questions (FAQ)

Q: Can DLP05LC-7-F be used as a direct replacement for DLP05LC-7?

A: Yes. The DLP05LC-7-F is electrically and mechanically identical to the discontinued DLP05LC-7, with matching voltage ratings, current handling, and package specifications. The primary difference is product status (active versus discontinued) and improved RoHS compliance.

Q: What is the key difference between SM05T1G and the original DLP05LC-7?

A: The SM05T1G has a lower clamping voltage (9.8V versus 11V) and features dual-channel protection instead of single-channel. Both maintain the same 5V standoff voltage, 17A peak current, and 300W power rating. The lower clamping voltage provides tighter voltage regulation, which may be beneficial in sensitive circuits.

Q: Is PESD5V0U1UT,215 suitable for all applications using DLP05LC-7?

A: No. The PESD5V0U1UT,215 has significantly reduced peak pulse current (5A) and power dissipation (80W) compared to the original specification (17A, 300W). This part is only suitable for low-current transient protection applications. High-current surge environments require the higher-rated alternatives.

Q: Are all substitute parts available in the same packaging format?

A: All substitute parts use the SOT-23-3 package for surface-mount assembly. However, packaging formats differ: DLP05LC-7-F is available in Cut Tape and Digi-Reel; SM05T1G is available in Cut Tape and Digi-Reel; PESD5V0U1UT,215 is available in Tape & Reel. Verify packaging availability with your supplier for production requirements.

Q: Do all substitutes meet RoHS compliance requirements?

A: The original DLP05LC-7 is RoHS non-compliant. All three substitute parts (DLP05LC-7-F, SM05T1G, and PESD5V0U1UT,215) are ROHS3 compliant, meeting current environmental and regulatory standards for new designs.

Q: What is the operating temperature range difference between substitutes?

A: DLP05LC-7, DLP05LC-7-F, and SM05T1G all operate from -55°C to 150°C (junction temperature). PESD5V0U1UT,215 extends the lower temperature limit to -65°C (ambient temperature), providing wider temperature range coverage for extreme environment applications.
