CFSH01-30 TR Schottky Diode Equivalent & Substitute Parts

Part Overview

The CFSH01-30 TR is an active Schottky diode manufactured by Central Semiconductor Corp, rated for 30V DC reverse voltage with 100mA average rectified current in a surface mount SOD-882 package. This component is designed for small signal rectification applications requiring low forward voltage drop and fast switching characteristics. The part is ROHS3 compliant with unlimited moisture sensitivity level (MSL 1) and remains in active production status. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, supply chain considerations, or design flexibility needs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CFSH01-30 TR is determined by the following critical electrical and mechanical parameters:

Voltage Rating Compatibility: The substitute part must maintain a DC reverse voltage rating (Vr) of 30V or greater to ensure equivalent or superior voltage withstand capability.

Current Rating Compatibility: The substitute part must support the required average rectified current (Io) of 100mA or greater. Higher current ratings provide design margin and operational flexibility.

Technology Consistency: Both the main part and substitute must utilize Schottky diode technology to maintain consistent forward voltage characteristics and switching speed performance.

Package Compatibility: The substitute part must be compatible with SOD-882 package footprint or equivalent surface mount package to ensure mechanical fit and PCB assembly compatibility.

Compliance Requirements: Both parts must maintain ROHS3 compliance and MSL 1 rating to satisfy regulatory and manufacturing process requirements.

Operating Temperature Range: The substitute part must support the required junction temperature range or provide an equivalent or extended range.

The BAS3010S02LRHE6327XTSA1 from Infineon Technologies meets all substitution criteria with equivalent voltage rating, higher current capacity, and compatible surface mount packaging.

Engineering Selection Recommendations

Primary Part Selection: The CFSH01-30 TR remains the specified component when inventory is available and supply chain continuity is assured. This part is in active production status with ROHS3 compliance and MSL 1 rating.

Substitute Part Selection: The BAS3010S02LRHE6327XTSA1 from Infineon Technologies is qualified as a direct substitute when the CFSH01-30 TR is unavailable. This substitute maintains equivalent voltage rating and package compatibility while providing higher current capacity (1A versus 100mA). Both parts are ROHS3 compliant with MSL 1 rating and active production status.

Design Margin Consideration: The BAS3010S02LRHE6327XTSA1 provides increased current handling capability, which may benefit circuit designs requiring operational margin above the 100mA specification.

Temperature Range Extension: The BAS3010S02LRHE6327XTSA1 supports an extended upper junction temperature range (-55°C to 150°C) compared to the CFSH01-30 TR (-65°C to 125°C), providing additional thermal margin for high-temperature applications.

Regulatory Compliance: Both parts satisfy ROHS3 and REACH requirements with equivalent compliance status.

Frequently Asked Questions (FAQ)

Q: Can the BAS3010S02LRHE6327XTSA1 be used as a direct replacement for the CFSH01-30 TR?

A: Yes. Both parts share identical voltage rating (30V), equivalent Schottky technology, compatible SOD-882 surface mount packaging, and equivalent compliance certifications (ROHS3, MSL 1). The substitute provides higher current capacity (1A versus 100mA), which is compatible with applications designed for 100mA operation.

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

A: The primary difference is current rating: the BAS3010S02LRHE6327XTSA1 is rated for 1A average rectified current compared to 100mA for the CFSH01-30 TR. Forward voltage and reverse leakage characteristics are measured at different test conditions due to the different current ratings. Capacitance is slightly higher in the substitute part (15pF versus 7pF).

Q: Are there package compatibility concerns?

A: No. Both parts use SOD-882 surface mount packaging with identical footprint and PCB assembly compatibility. The supplier device package designation differs (SOD-882 for CFSH01-30 TR versus PG-TSLP-2-17 for BAS3010S02LRHE6327XTSA1), but both reference the same physical SOD-882 package standard.

Q: What is the temperature range difference?

A: The CFSH01-30 TR operates from -65°C to 125°C junction temperature. The BAS3010S02LRHE6327XTSA1 operates from -55°C to 150°C. The substitute provides a 25°C higher maximum junction temperature rating, which may be beneficial for high-temperature applications.

Q: Are both parts compliant with environmental and regulatory standards?

A: Yes. Both the CFSH01-30 TR and BAS3010S02LRHE6327XTSA1 are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. Both maintain MSL 1 (unlimited) moisture sensitivity level.

Q: Which part should be selected for new designs?

A: Selection depends on supply chain availability and design requirements. Both parts are active production status. The BAS3010S02LRHE6327XTSA1 may be preferred for designs requiring higher current capacity or extended temperature range. The CFSH01-30 TR may be preferred when lower capacitance is a design requirement.
