BAT54S RF Equivalent & Substitute Parts (Diodes, Rectifiers)

Part Overview

The BAT54S RF by Taiwan Semiconductor Corporation is a surface-mount Schottky diode in the SOT-23 (TO-236-3, SC-59, SOT-23-3) package. It operates with a maximum reverse voltage of 30 V and a maximum average rectified current of 200 mA. Its low forward voltage and fast reverse recovery time (5 ns) cater to small signal applications. Maintaining continuity in critical designs may require functionally compatible alternatives, especially for inventory management, multisourcing, or compliance requirements, as well as aligning with production needs.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the BAT54S RF in the diodes, rectifiers category is based strictly on the following key parameters:

• Schottky technology
• Maximum DC reverse voltage of 30 V
• Average rectified current of 200 mA
• Forward voltage drop of 1 V at 100 mA
• Reverse recovery time of 5 ns
• Reverse leakage current at 2 µA @ 25 V
• Capacitance of 10 pF @ 1 V, 1 MHz
• Identical package/case (TO-236-3, SC-59, SOT-23-3) and mounting type
• Equivalent operating temperature range
• RoHS3 compliance and REACH unaffected status
• Moisture Sensitivity Level 1 (Unlimited)
• Active product status

Only components with all of these parameters can be considered direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

Both BAT54S RF and BAT54S RFG are active products, RoHS3 compliant, and REACH unaffected with a Moisture Sensitivity Level of 1 (Unlimited). Selection between these alternatives can be based on inventory availability, packaging, and order fulfillment requirements, without electrical or compliance divergence according to provided data.

Frequently Asked Questions (FAQ)

Q1: What electrical parameters ensure compatibility between BAT54S RF and substitute diodes?
A1: Compatibility is determined by Schottky technology, reverse voltage (30 V), current rating (200 mA), forward voltage (1 V at 100 mA), reverse recovery time (5 ns), reverse leakage (2 µA @ 25 V), and capacitance (10 pF @ 1 V, 1 MHz).

Q2: Are there any differences in packaging or mounting between BAT54S RF and BAT54S RFG?
