Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the BAT54T-TP are identified through parametric equivalence matching. The primary substitution criteria are based on the following electrical and mechanical parameters:

Critical Matching Parameters:

• Voltage - DC Reverse (Vr) (Max): 30 V
• Current - Average Rectified (Io): 200 mA
• Voltage - Forward (Vf) (Max) @ If: 1 V @ 100 mA
• Reverse Recovery Time (trr): 5 ns
• Current - Reverse Leakage @ Vr: 2 µA @ 25 V
• Package / Case: SOT-523
• Mounting Type: Surface Mount
• Technology: Schottky
• Operating Temperature - Junction: -65°C ~ 125°C

Parts meeting all critical parameters are classified as parametric equivalents and may be substituted without circuit redesign, provided compliance requirements and packaging format are compatible with the application environment.

Parameter Comparison

Engineering Selection Recommendations

The BAT54T-7-F manufactured by Diodes Incorporated is a parametric equivalent to the BAT54T-TP. Both components share identical electrical specifications across all critical parameters including reverse voltage rating, forward current capacity, forward voltage drop, and reverse recovery time. Both parts maintain Active product status and ROHS3 compliance.

The BAT54T-7-F includes AEC-Q101 automotive qualification, indicating suitability for automotive-grade applications. This qualification is an additional compliance attribute not specified for the BAT54T-TP.

The primary difference between these parts is packaging format: the BAT54T-TP is supplied in Cut Tape (CT) & Digi-Reel® format, while the BAT54T-7-F is supplied in Tape & Reel (TR) format. Packaging format selection depends on assembly process requirements and procurement volume specifications. Both formats are compatible with standard surface mount assembly equipment.

Selection between these equivalent parts should be based on packaging availability, supply chain requirements, and any automotive qualification mandates specific to the end application.

Frequently Asked Questions (FAQ)

Q: Can the BAT54T-7-F replace the BAT54T-TP in existing circuit designs?

A: Yes. The BAT54T-7-F meets all electrical specifications of the BAT54T-TP, including reverse voltage rating (30V), forward current capacity (200mA), forward voltage drop (1V @ 100mA), and reverse recovery time (5ns). Both components use the SOT-523 surface mount package and operate across the same temperature range (-65°C to 125°C).

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

A: Cut Tape (CT) & Digi-Reel® packaging supplies components on tape that can be cut to length for manual or semi-automated assembly. Tape & Reel (TR) packaging supplies components on continuous tape wound on a reel, optimized for high-volume automated assembly. Both formats contain the same component in the same SOT-523 package; the difference is in the delivery and handling format.

Q: Are there compliance differences between BAT54T-TP and BAT54T-7-F?

A: Both parts are ROHS3 compliant and REACH unaffected. The BAT54T-7-F includes AEC-Q101 automotive qualification, which is an additional certification not specified for the BAT54T-TP. If automotive qualification is required for the application, the BAT54T-7-F is the appropriate selection.

Q: What does the capacitance specification difference mean?

A: The BAT54T-TP specifies 10pF @ 1V, 1MHz, while the BAT54T-7-F specifies 10pF @ 10V, 1MHz. Both measurements yield the same capacitance value (10pF) at 1MHz frequency. The measurement voltage differs, but the resulting capacitance is equivalent for circuit design purposes.

Q: Can these parts be used interchangeably in high-speed switching applications?

A: Yes. Both parts have identical reverse recovery time specifications (5ns), which is the critical parameter for high-speed switching performance. The SOT-523 package and surface mount configuration are identical, ensuring compatible circuit board layout and assembly processes.

Q: What inventory considerations apply to these substitute parts?

A: The BAT54T-TP has 3,812 pieces in stock. The BAT54T-7-F has 36,300 pieces in stock. Availability and lead time may differ between manufacturers and suppliers. Procurement decisions should account for current inventory levels and supply chain requirements.
