BAT54T,115 Equivalent & Substitute Parts

Part Overview

The BAT54T,115 is a Schottky diode manufactured by NXP USA Inc., rated for 30 V DC reverse voltage and 200 mA average rectified current in an SC-75 surface mount package. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. Substitute parts must maintain electrical equivalence across voltage, current, and thermal specifications while accommodating different package formats.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BAT54T,115 is based on strict electrical parameter equivalence. All substitute parts must satisfy the following criteria:

Mandatory Electrical Parameters:

• Voltage - DC Reverse (Vr) (Max): 30 V
• Current - Average Rectified (Io): 200 mA
• Voltage - Forward (Vf) (Max) @ If: 800 mV @ 100 mA
• Current - Reverse Leakage @ Vr: 2 µA @ 25 V
• Capacitance @ Vr, F: 10 pF @ 1V, 1MHz
• Technology: Schottky
• Mounting Type: Surface Mount

Allowable Variations:

• Package / Case format (SC-75, SOD-323, TO-236AB, SOD-882)
• Operating Temperature - Junction (150°C or lower acceptable)
• Product status (Active preferred over Obsolete)
• Manufacturer (NXP USA Inc., Nexperia USA Inc., NXP Semiconductors)

All three substitute parts meet these criteria while offering different package options and improved availability.

Parameter Comparison

Engineering Selection Recommendations

1PS76SB10,115 (SOD-323 Package)

This substitute is an active product from Nexperia USA Inc. with automotive-grade qualification (AEC-Q101). It meets all electrical parameters of the BAT54T,115 with the exception of operating temperature maximum (125°C vs. 150°C). This part is suitable for applications where the junction temperature does not exceed 125°C. The SOD-323 package is widely supported in modern PCB designs. Inventory availability is high (16155 Pcs).

BAT54,215 (TO-236AB Package)

This substitute is an active product from Nexperia USA Inc. with full electrical and thermal equivalence to the BAT54T,115, including 150°C maximum junction temperature and 5 ns reverse recovery time. The TO-236AB package (also designated SC-59 or SOT-23-3) is a standard surface mount format with extensive design tool support. This part offers the highest inventory availability (546150 Pcs) and is recommended for applications requiring direct thermal performance matching.

BAT54L,315 (SOD-882 Package)

This substitute is an active product from NXP Semiconductors with full electrical equivalence and 150°C maximum junction temperature. The SOD-882 package (DFN1006-2) represents the smallest form factor among the substitutes, suitable for space-constrained applications. Inventory availability is moderate (3300 Pcs).

Frequently Asked Questions (FAQ)

Q: Can BAT54T,115 be directly replaced with 1PS76SB10,115?

A: Electrical substitution is valid for all parameters except operating temperature maximum. The 1PS76SB10,115 is rated to 125°C junction temperature versus 150°C for the BAT54T,115. Substitution is acceptable if circuit design ensures junction temperature remains below 125°C. Package change from SC-75 to SOD-323 requires PCB layout modification.

Q: What is the difference between BAT54,215 and BAT54T,115?

A: Both parts are electrically equivalent across all specified parameters, including 30 V reverse voltage, 200 mA current rating, 800 mV forward voltage, and 150°C maximum junction temperature. The primary difference is package format: BAT54T,115 uses SC-75 (SOT-416), while BAT54,215 uses TO-236AB (SOT-23-3). Both are surface mount technologies.

Q: Is BAT54L,315 suitable for high-temperature applications?

A: BAT54L,315 is rated to 150°C maximum junction temperature, matching the BAT54T,115. However, the SOD-882 package (DFN1006-2) is a very small form factor. Thermal performance depends on PCB copper area and thermal management design. Verify thermal dissipation capability for the specific application.

Q: Why is BAT54T,115 listed as obsolete?

A: Product obsolescence is a manufacturer lifecycle decision. Active substitute parts with equivalent electrical specifications are available from Nexperia USA Inc. and NXP Semiconductors. Migration to an active product is recommended for long-term supply chain stability.

Q: Can these substitutes be used interchangeably on the same PCB?

A: No. Each substitute uses a different package format (SOD-323, TO-236AB, or SOD-882), requiring different PCB footprints and land patterns. A single PCB design must specify one package variant. Substitution requires PCB redesign and re-layout.

Q: Are all substitutes RoHS compliant?

A: BAT54T,115, 1PS76SB10,115, and BAT54,215 are explicitly ROHS3 compliant. BAT54L,315 RoHS status is not specified in the provided data. Verify RoHS compliance documentation for BAT54L,315 if regulatory compliance is required.

Q: What is the inventory advantage of BAT54,215?

A: BAT54,215 has significantly higher inventory (546150 Pcs) compared to other substitutes, providing superior supply chain availability and shorter lead times for production requirements.
