ESDLC5V0L4-TP Equivalent & Substitute Parts

Part Overview

The ESDLC5V0L4-TP is a 4-channel unidirectional Transient Voltage Suppressor (TVS) diode manufactured by Micro Commercial Co, 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 20W peak pulse power rating in a compact SOT-553 package.

The ESDLC5V0L4-TP has reached obsolete product status. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain reliability, and support ongoing production requirements for applications utilizing this TVS diode configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ESDLC5V0L4-TP are identified based on the following critical electrical and mechanical parameters:

Primary Substitution Criteria:

• Unidirectional channel configuration: 4 channels
• Reverse standoff voltage: 5V nominal
• Breakdown voltage minimum: 6V
• Clamping voltage maximum: 11V at Ipp
• Package type: SOT-553 (primary) or equivalent surface-mount package
• Operating temperature range: -55°C to 150°C
• Zener diode type classification

Substitution Logic: Parts meeting all primary electrical parameters (standoff voltage, breakdown voltage, clamping voltage, and channel count) within the specified tolerances are classified as direct substitutes. Package variations are permitted when mechanical compatibility is maintained for the application's PCB layout and assembly process. Product status (active vs. obsolete) and compliance certifications (RoHS, REACH) are secondary considerations that support long-term supply chain viability.

Parameter Comparison

Engineering Selection Recommendations

SMDA05/TR7 (Microchip Technology) is the primary substitute for the ESDLC5V0L4-TP. This part maintains identical electrical specifications for reverse standoff voltage (5V), breakdown voltage (6V minimum), and clamping voltage (11V maximum). Both components operate across the same temperature range (-55°C to 150°C). The SMDA05/TR7 is currently in active production status, ensuring long-term availability and supply chain stability. However, the SMDA05/TR7 uses an 8-SOIC package rather than SOT-553, requiring PCB layout modification. The part carries RoHS non-compliant status, which may impact applications with strict environmental compliance requirements.

NZQA5V6AXV5T1G (onsemi) maintains the SOT-553 package form factor, eliminating PCB redesign requirements. This part is in active production and ROHS3 compliant. However, the reverse standoff voltage is 3V (versus 5V for the main part) and the clamping voltage is 13V (versus 11V), representing a 2V deviation in standoff protection and 2V increase in clamping response. These electrical differences may affect circuit protection performance in applications with tight voltage tolerance specifications.

Selection between these substitutes depends on design priorities: package compatibility and compliance requirements (NZQA5V6AXV5T1G) versus electrical parameter matching and higher power dissipation capability (SMDA05/TR7).

Frequently Asked Questions (FAQ)

Q: Can the NZQA5V6AXV5T1G be used as a direct replacement for the ESDLC5V0L4-TP?

A: The NZQA5V6AXV5T1G shares the same SOT-553 package and 4-channel configuration, but differs in reverse standoff voltage (3V vs. 5V) and clamping voltage (13V vs. 11V). This part is suitable only if the application can tolerate lower standoff protection and higher clamping voltage. Verify circuit protection requirements before substitution.

Q: What are the package differences between SMDA05/TR7 and ESDLC5V0L4-TP?

A: The ESDLC5V0L4-TP uses SOT-553 packaging, while the SMDA05/TR7 uses 8-SOIC (0.154", 3.90mm width). The 8-SOIC package is larger and requires different PCB footprint design. Mechanical compatibility must be verified for the target application's board layout.

Q: Why is the ESDLC5V0L4-TP obsolete?

A: The ESDLC5V0L4-TP has reached end-of-life status with Micro Commercial Co. Both substitute parts (NZQA5V6AXV5T1G and SMDA05/TR7) are in active production, providing continued availability for new designs and production support.

Q: Does RoHS compliance matter for my application?

A: RoHS compliance is mandatory for products sold in the European Union and many other markets. The NZQA5V6AXV5T1G is ROHS3 compliant, while the SMDA05/TR7 is RoHS non-compliant. Verify regulatory requirements for your target market before final part selection.

Q: What is the significance of capacitance differences between these parts?

A: Capacitance values (14pF for ESDLC5V0L4-TP, 13pF for NZQA5V6AXV5T1G, and 400pF for SMDA05/TR7) affect high-frequency circuit behavior. The SMDA05/TR7's significantly higher capacitance may impact signal integrity in high-speed applications. Verify capacitance compatibility with your circuit's frequency requirements.
