Würth Elektronik 824014881 TVS Diode Equivalent & Substitute Parts

Part Overview

The Würth Elektronik 824014881 is a Transient Voltage Suppressor (TVS) diode in a 9-UDFN surface mount package, designed for general-purpose voltage clamping applications. This steering diode features 8 unidirectional channels with a 1.2V reverse standoff voltage and 7V typical clamping voltage at peak pulse current.

The 824014881 is classified as Obsolete. Locating equivalent substitute parts is necessary to maintain design continuity and ensure component availability for new production runs and field replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for TVS diodes is determined by the following critical parameters:

• Package Compatibility: Both parts must use the identical 9-UDFN (DFN3810-9) surface mount package to ensure PCB footprint compatibility
• Channel Configuration: Both parts must maintain 8 unidirectional channels for steering diode functionality
• Voltage Ratings: Reverse standoff voltage, breakdown voltage, and clamping voltage must be within acceptable operating ranges for the target application
• Current Handling: Peak pulse current rating must meet or exceed the application requirement
• Thermal Specifications: Operating temperature range must cover the intended deployment environment
• Compliance Standards: RoHS and REACH compliance status must satisfy regulatory requirements

The substitute part 824014883 shares identical package geometry, channel count, and thermal specifications with the main part. Voltage and current parameters differ to accommodate higher transient energy levels while maintaining the same physical footprint and interface characteristics.

Parameter Comparison

Engineering Selection Recommendations

The 824014883 is the manufacturer-recommended substitute for the obsolete 824014881. Both parts are manufactured by Würth Elektronik and share identical package geometry, thermal operating range, and regulatory compliance certifications (ROHS3 Compliant, REACH Unaffected).

The 824014883 is currently in active production status, ensuring long-term availability and supply chain continuity. The substitute part accommodates higher transient voltage and current levels (9V clamping vs. 7V, 5A vs. 4A peak pulse current) while maintaining the same physical footprint and interface characteristics.

Selection of the 824014883 is appropriate for applications where the higher voltage and current ratings do not conflict with circuit design constraints. Designs requiring the specific lower voltage thresholds of the 824014881 may require alternative component selection outside the WE-TVS series.

Frequently Asked Questions (FAQ)

Q: Can the 824014883 be used as a direct replacement for the 824014881 on existing PCBs?

A: Yes, the 824014883 uses the identical 9-UDFN (DFN3810-9) surface mount package and footprint. No PCB layout modifications are required for physical installation.

Q: What are the key differences between these two parts?

A: The primary differences are voltage and current ratings. The 824014883 provides higher clamping voltage (9V vs. 7V) and peak pulse current (5A vs. 4A). Both parts maintain identical package geometry, channel configuration, and operating temperature range.

Q: Are there compliance or certification differences between the two parts?

A: No. Both parts carry identical RoHS3 compliance and REACH Unaffected status. Moisture sensitivity level (MSL 3, 168 Hours) is the same for both components.

Q: Why is the 824014881 listed as Obsolete?

A: The 824014881 has been discontinued by Würth Elektronik. The 824014883 represents the active product line continuation within the WE-TVS series.

Q: Does the higher capacitance of the 824014883 (0.5pF vs. 0.35pF) affect circuit performance?

A: Capacitance differences are minimal (0.15pF) and measured at 1MHz. Impact on circuit performance depends on specific application frequency and impedance characteristics. Consult application-specific circuit analysis for confirmation.

Q: What is the operating temperature range for both parts?

A: Both the 824014881 and 824014883 operate across -55°C to 85°C ambient temperature range (TA).
