RB088NS-40TL Equivalent & Substitute Parts

Part Overview

The RB088NS-40TL is a Schottky diode array manufactured by Rohm Semiconductor, configured as a 1 Pair Common Cathode arrangement with a maximum reverse voltage rating of 40 V and average rectified current of 10 A per diode. The device is packaged in a Surface Mount TO-263-3 (D2PAK) configuration with 2 leads plus tab, designated as LPDS supplier package. This component is classified as Active product status and is ROHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Equivalent and substitute parts are identified when they maintain identical or superior electrical performance characteristics while maintaining compatibility with the same package footprint and mounting requirements. Substitution becomes necessary due to inventory availability, supply chain considerations, or specific application requirements such as automotive qualification.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RB088NS-40TL is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Diode configuration must be 1 Pair Common Cathode
• Technology must be Schottky
• Maximum reverse voltage (Vr) must be 40 V or greater
• Average rectified current (Io) per diode must be 10 A or greater
• Forward voltage (Vf) at 5 A must not exceed 770 mV
• Fast recovery speed characteristic (≤ 500ns, > 200mA)
• Reverse leakage current must not exceed 3 µA @ 40 V
• Junction temperature rating must support 150°C operation

Mechanical Equivalence Criteria:

• Package must be TO-263-3, D2PAK (2 Leads + Tab), TO-263AB
• Mounting type must be Surface Mount
• Supplier device package must be LPDS

Compliance Equivalence Criteria:

• RoHS3 compliance required
• MSL rating of 1 (Unlimited) required
• REACH Unaffected status required

The RB088NS-40TL has one identified parametric equivalent: RB088NS-40FHTL. This substitute maintains all electrical and mechanical specifications while differing only in packaging format (Cut Tape & Digi-Reel® versus Tape & Reel) and includes automotive-grade qualification (AEC-Q101).

Parameter Comparison

Engineering Selection Recommendations

RB088NS-40TL Selection: Select the RB088NS-40TL when standard industrial-grade Schottky diode array performance is required with Tape & Reel packaging format. This part maintains Active product status with full ROHS3 compliance and unlimited moisture sensitivity rating. The component is suitable for general-purpose rectification applications requiring 40 V reverse voltage and 10 A average rectified current per diode.

RB088NS-40FHTL Selection: Select the RB088NS-40FHTL when automotive-grade qualification is required or when Cut Tape & Digi-Reel® packaging format is preferred. This substitute maintains identical electrical and thermal specifications while providing AEC-Q101 automotive qualification. The part is suitable for automotive applications or when higher reliability standards are mandated. Both parts share identical electrical performance and package footprint compatibility.

Compliance Considerations: Both parts maintain ROHS3 compliance, REACH Unaffected status, and MSL 1 (Unlimited) rating. Selection between these parts should be based on application requirements (automotive versus industrial) and packaging format availability rather than electrical performance differences.

Frequently Asked Questions (FAQ)

Q: Can RB088NS-40FHTL be used as a direct replacement for RB088NS-40TL?

A: Yes. The RB088NS-40FHTL is a parametric equivalent with identical electrical specifications, thermal ratings, and package footprint. The only differences are packaging format (Cut Tape & Digi-Reel® versus Tape & Reel) and automotive-grade qualification (AEC-Q101). Both parts are electrically and mechanically interchangeable in the same circuit design.

Q: What is the significance of the AEC-Q101 qualification on the RB088NS-40FHTL?

A: AEC-Q101 is an automotive electronics qualification standard. The RB088NS-40FHTL meets this qualification, making it suitable for automotive applications where higher reliability and quality standards are required. The RB088NS-40TL does not carry this qualification but maintains identical electrical performance for non-automotive applications.

Q: Are the package footprints identical between RB088NS-40TL and RB088NS-40FHTL?

A: Yes. Both parts use the TO-263-3 D2PAK package with 2 leads plus tab (TO-263AB). The physical footprint, pin spacing, and mounting requirements are identical. PCB layout and assembly processes require no modification when substituting between these parts.

Q: What does the packaging format difference (Tape & Reel versus Cut Tape & Digi-Reel®) mean for procurement?

A: Tape & Reel (TR) format supplies components on continuous tape in reel quantities, typically used for high-volume automated assembly. Cut Tape (CT) & Digi-Reel® format provides components on cut tape segments or alternative reel formats, offering flexibility for lower-volume orders or mixed component procurement. The electrical and mechanical specifications remain identical regardless of packaging format.

Q: Can either part be used in applications requiring reverse voltage exceeding 40 V?

A: No. Both RB088NS-40TL and RB088NS-40FHTL have a maximum reverse voltage rating of 40 V. Applications requiring higher reverse voltage ratings require selection of alternative diode array models with higher voltage specifications.

Q: What is the maximum average rectified current per diode for these parts?

A: Both parts are rated for 10 A average rectified current per diode. Applications requiring higher current capacity require selection of alternative diode array models with higher current ratings.

Q: Are both parts suitable for high-temperature applications?

A: Both parts support junction temperature operation up to 150°C maximum. Applications requiring operation above this temperature require selection of alternative diode array models with higher temperature ratings.

Q: What is the forward voltage drop at rated current for these parts?

A: Both parts have a maximum forward voltage of 770 mV at 5 A forward current. This specification is identical between RB088NS-40TL and RB088NS-40FHTL and determines power dissipation characteristics in rectification circuits.
