BAT54SW Equivalent & Substitute Parts

Part Overview

The BAT54SW is a Schottky diode array in a 1 Pair Series Connection configuration, manufactured by Taiwan Semiconductor Corporation. This component operates at a maximum reverse voltage of 30 V with a rectified current rating of 200 mA per diode. The device is housed in an SC-70, SOT-323 surface mount package and is classified as Active product status with ROHS3 compliance. Alternative equivalent parts may be required due to inventory availability, supplier lead times, or specific packaging requirements such as Tape & Reel delivery formats.

Substitute Part Grouping Explanation

The BAT54SW-7-F manufactured by Diodes Incorporated qualifies as a direct electrical and mechanical substitute. Substitution is valid based on the following criteria:

Electrical Parameter Equivalence:

• Identical diode configuration: 1 Pair Series Connection
• Identical technology: Schottky
• Identical maximum reverse voltage: 30 V
• Identical rectified current rating: 200 mA (DC) per diode
• Identical forward voltage specification: 1 V @ 100 mA
• Identical reverse recovery time: 5 ns
• Identical reverse leakage current: 2 µA @ 25 V

Mechanical Parameter Equivalence:

• Identical package type: SC-70, SOT-323
• Identical mounting type: Surface Mount
• Identical supplier device package: SOT-323

Compliance Equivalence:

• Both parts maintain ROHS3 compliance
• Both parts have REACH Unaffected status
• Both parts classified under identical ECCN and HTSUS codes

The primary difference between the main part and substitute is the packaging format (Tape & Reel for BAT54SW-7-F) and the extended operating temperature range specification for the substitute part.

Parameter Comparison

Engineering Selection Recommendations

Both the BAT54SW and BAT54SW-7-F are Active product status components with full ROHS3 and REACH compliance. Selection between these parts should be based on the following factors:

BAT54SW (Taiwan Semiconductor Corporation):

• Select when standard packaging format is acceptable
• Current inventory: 248,378 pieces available

BAT54SW-7-F (Diodes Incorporated):

• Select when Tape & Reel packaging format is required for automated assembly processes
• Select when extended operating temperature range specification (-65°C ~ 125°C) is required
• Select when Moisture Sensitivity Level (MSL) 1 (Unlimited) specification is required
• Current inventory: 65,400 pieces available

Both parts maintain identical electrical performance characteristics and are suitable for direct substitution in applications requiring Schottky diode arrays with 30 V reverse voltage and 200 mA rectified current ratings in SOT-323 surface mount packages.

Frequently Asked Questions (FAQ)

Q: Can BAT54SW-7-F be used as a direct replacement for BAT54SW?
