PRTR5V0U2D,115 Equivalent & Substitute Parts

Part Overview

The PRTR5V0U2D,115 is a steering transient voltage suppressor (TVS) diode manufactured by NXP Semiconductors, designed for rail-to-rail protection with dual unidirectional channels. This component features a 5.5V reverse standoff voltage and 6V minimum breakdown voltage in a compact SC-74 surface mount package. The device is qualified to AEC-Q101 automotive standards and complies with RoHS3 and REACH regulations.

This part is classified as obsolete. Identifying equivalent substitute components ensures design continuity and supply chain reliability for applications requiring dual-channel steering TVS protection with automotive-grade qualification.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PRTR5V0U2D,115 is determined by the following critical parameters:

Electrical Compatibility Criteria:

• Dual unidirectional channels (steering configuration)
• Reverse standoff voltage range: 5.5V nominal
• Breakdown voltage minimum: 6V
• Rail-to-rail protection topology

Mechanical & Environmental Criteria:

• Surface mount packaging
• Automotive-grade qualification (AEC-Q101)
• RoHS3 compliance
• Operating temperature range: -40°C minimum to 85°C minimum

Functional Requirements:

• Power line protection capability
• Transient voltage suppression for dual-channel applications

The ESDALCL6-2SC6 from STMicroelectronics meets these substitution criteria through equivalent electrical performance and automotive qualification, though it operates at a higher maximum junction temperature (125°C vs. 85°C).

Parameter Comparison

Engineering Selection Recommendations

The ESDALCL6-2SC6 is available as an active product with current manufacturing support, addressing the supply discontinuation of the PRTR5V0U2D,115. Both components comply with RoHS3 regulations and provide dual-channel steering TVS protection.

Key considerations for selection:

Voltage Standoff Difference: The ESDALCL6-2SC6 operates at a 3V reverse standoff voltage compared to the 5.5V specification of the original part. This lower standoff voltage requires verification against circuit protection requirements.

Package Transition: The ESDALCL6-2SC6 uses SOT-23-6 packaging versus the SC-74 package of the original component. PCB layout and footprint modifications are necessary.

Temperature Rating: The ESDALCL6-2SC6 supports extended junction temperature operation to 125°C, providing thermal margin beyond the original part's 85°C ambient rating.

Automotive Qualification: Confirm AEC-Q101 or equivalent automotive qualification status of the ESDALCL6-2SC6 for applications requiring automotive-grade components.

Frequently Asked Questions (FAQ)

Q: Can the ESDALCL6-2SC6 directly replace the PRTR5V0U2D,115 without circuit modifications?

A: Direct replacement requires verification of the 3V reverse standoff voltage against your circuit protection threshold. The lower standoff voltage may affect transient suppression performance. Package differences necessitate PCB layout changes.

Q: What is the significance of the reverse standoff voltage difference?

A: Reverse standoff voltage determines the maximum voltage the TVS diode can withstand without conducting. The PRTR5V0U2D,115 at 5.5V provides higher voltage tolerance before clamping compared to the ESDALCL6-2SC6 at 3V. Circuit operating voltage must remain below the standoff rating.

Q: Are both parts suitable for automotive applications?

A: The PRTR5V0U2D,115 carries AEC-Q101 automotive qualification. The ESDALCL6-2SC6 automotive qualification status is not specified in available data. Confirm compliance requirements with your application specifications.

Q: How do package differences affect implementation?

A: The SC-74 package (PRTR5V0U2D,115) and SOT-23-6 package (ESDALCL6-2SC6) have different pin configurations and footprints. PCB redesign is required, including trace routing and component placement adjustments.

Q: What is the impact of the extended temperature rating on the ESDALCL6-2SC6?

A: The 125°C maximum junction temperature of the ESDALCL6-2SC6 exceeds the 85°C ambient rating of the original part, providing additional thermal headroom in high-temperature environments. This does not affect substitution compatibility but may improve reliability in thermally constrained applications.
