BAT54C Equivalent & Substitute Parts

Part Overview

The BAT54C is a Schottky diode array in a surface mount package, configured as 1 pair common cathode with a maximum reverse voltage of 30 V and average rectified current of 200 mA per diode. The device is classified as Active product status and is RoHS3 compliant. Equivalent and substitute parts are identified to provide design flexibility, support supply chain continuity, and accommodate different packaging or sourcing requirements while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BAT54C is determined by strict equivalence across the following critical parameters:

• Diode Configuration: 1 Pair Common Cathode topology must be maintained
• Technology: Schottky diode technology
• Voltage Rating: Maximum DC reverse voltage of 30 V
• Current Rating: Average rectified current of 200 mA per diode
• Forward Voltage: Maximum forward voltage of 1 V @ 100 mA
• Reverse Recovery Time: 5 ns specification
• Reverse Leakage Current: 2 µA @ 25 V
• Package: TO-236-3, SC-59, SOT-23-3 surface mount package
• Compliance: RoHS3 compliant status

Substitute parts must match all electrical parameters and package specifications. Packaging format (Cut Tape, Tape & Reel) represents a logistical variation and does not affect electrical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both BAT54C variants meet the core electrical and mechanical requirements for direct substitution. The Taiwan Semiconductor Corporation BAT54C and Good-Ark Semiconductor BAT54C are electrically equivalent across all specified parameters including voltage rating, current capacity, forward voltage characteristics, and reverse recovery time.

The Good-Ark Semiconductor variant provides an extended operating temperature range (-65°C ~ 150°C) compared to the Taiwan Semiconductor Corporation variant (-55°C ~ 125°C). This extended range is a superset of the original specification and does not restrict compatibility in applications operating within the original temperature range.

Both parts are RoHS3 compliant and REACH unaffected, meeting regulatory requirements. Selection between manufacturers may be based on availability, packaging format preference (Cut Tape & Digi-Reel versus Tape & Reel), or supply chain requirements. No electrical performance trade-offs exist between the two options.

Frequently Asked Questions (FAQ)

Q: Can the Good-Ark Semiconductor BAT54C replace the Taiwan Semiconductor Corporation BAT54C in existing designs?

A: Yes. Both parts are electrically identical across all specified parameters including voltage rating, current capacity, forward voltage, and reverse recovery time. The package and mounting type are identical. Direct substitution is supported.

Q: What is the significance of the extended temperature range in the Good-Ark Semiconductor variant?

A: The Good-Ark Semiconductor BAT54C operates from -65°C to 150°C, compared to -55°C to 125°C for the Taiwan Semiconductor Corporation variant. This extended range encompasses the original specification and provides additional margin for applications operating at temperature extremes. Applications designed for the original temperature range remain fully compatible.

Q: Are there differences in packaging between the two BAT54C variants?

A: Both variants use the same TO-236-3, SC-59, SOT-23-3 surface mount package. The packaging format differs (Cut Tape & Digi-Reel versus Tape & Reel), which is a logistical consideration and does not affect electrical or mechanical compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both BAT54C variants are RoHS3 compliant and REACH unaffected. Regulatory compliance is equivalent between manufacturers.

Q: What parameters must remain constant for a part to be considered a true substitute for the BAT54C?

A: The following parameters must match: diode configuration (1 Pair Common Cathode), Schottky technology, 30 V maximum reverse voltage, 200 mA average rectified current per diode, 1 V maximum forward voltage at 100 mA, 5 ns reverse recovery time, 2 µA reverse leakage current at 25 V, and TO-236-3, SC-59, SOT-23-3 surface mount package.
