BAT54SD REG Equivalent & Substitute Parts

Part Overview

The BAT54SD REG is a Schottky diode array manufactured by Taiwan Semiconductor Corporation, configured as a 2 pair series connection rated for 30 V DC reverse voltage and 200 mA average rectified current per diode. The device is packaged in a 6-TSSOP (SC-88, SOT-363) surface mount configuration and is classified as an active product with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1).

Equivalent and substitute parts are identified based on matching electrical characteristics, mechanical packaging, and compliance certifications. Alternative sources provide identical functional performance within the same package footprint, enabling design flexibility and supply chain optimization.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the BAT54SD REG are qualified based on strict parametric equivalence across all electrical and mechanical specifications. The substitution criteria are:

Mandatory Matching Parameters:

• Diode Configuration: 2 Pair Series Connection
• Technology: Schottky
• Voltage - DC Reverse (Vr) (Max): 30 V
• Current - Average Rectified (Io) (per Diode): 200 mA (DC)
• Voltage - Forward (Vf) (Max) @ If: 1 V @ 100 mA
• Reverse Recovery Time (trr): 5 ns
• Current - Reverse Leakage @ Vr: 2 µA @ 25 V
• Operating Temperature - Junction: -65°C to 125°C
• Package / Case: 6-TSSOP, SC-88, SOT-363
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

All identified substitute parts meet these criteria. Variations in packaging format (Tape & Reel vs. Cut Tape) and manufacturer source do not affect electrical or mechanical compatibility. One substitute part (BAT54SDWQ-7-F) includes automotive-grade qualification (AEC-Q101), which represents an enhanced specification level suitable for automotive applications while maintaining full compatibility with standard industrial applications.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts are active products with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1), ensuring regulatory and environmental compatibility with the BAT54SD REG across industrial applications.

For Standard Industrial Applications: BAT54SDW-7-F (Diodes Incorporated) and BAT54SDW-TP (Micro Commercial Co) are direct functional equivalents with identical electrical specifications and operating temperature range. Selection between these options is determined by packaging format requirements: Cut Tape (CT) & Digi-Reel® for BAT54SDW-7-F or Tape & Reel (TR) for BAT54SDW-TP.

For Automotive Applications: BAT54SDWQ-7-F (Diodes Incorporated) is qualified to AEC-Q101 automotive standards while maintaining full parametric equivalence to the BAT54SD REG. This part is suitable for automotive-grade designs and provides enhanced qualification documentation.

For Alternative Sourcing: BAT54BRW-7-F (Diodes Incorporated) and BAT54BRW-TP (Micro Commercial Co) provide equivalent electrical performance and packaging with alternative manufacturer sourcing options, supporting supply chain diversification.

Frequently Asked Questions (FAQ)

Q: Can BAT54SDWQ-7-F be used as a direct replacement for BAT54SD REG in non-automotive applications?

A: Yes. BAT54SDWQ-7-F meets all electrical and mechanical specifications of the BAT54SD REG. The AEC-Q101 automotive qualification represents an enhanced specification level and does not restrict use in standard industrial applications.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel® packaging formats?

A: Packaging format affects supply chain logistics and handling. Tape & Reel (TR) is supplied on continuous tape for automated assembly. Cut Tape (CT) & Digi-Reel® provides flexibility for smaller quantity orders. Electrical and mechanical specifications are identical across all packaging formats.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All identified substitute parts are ROHS3 compliant with unlimited moisture sensitivity level (MSL 1), matching the compliance profile of the BAT54SD REG.

Q: Can substitute parts be mixed in the same design or assembly?

A: Yes. All substitute parts are parametrically equivalent and share identical package footprints (6-TSSOP, SC-88, SOT-363). Mixing substitute parts from different manufacturers does not affect circuit performance or reliability.

Q: What is the significance of the 5 ns reverse recovery time specification?

A: Reverse recovery time (trr) of 5 ns indicates fast switching performance characteristic of Schottky diode technology. This specification is identical across all substitute parts and determines suitability for high-frequency switching applications.

Q: Are there any thermal or reliability differences between substitute parts?

A: All substitute parts share identical operating temperature range (-65°C to 125°C junction temperature) and reverse leakage current specifications (2 µA @ 25 V). Thermal and reliability performance are equivalent across all qualified substitutes.
