BAT30AWFILM Equivalent & Substitute Parts

Part Overview

The BAT30AWFILM is a Schottky diode array manufactured by STMicroelectronics, configured as 1 Pair Common Anode with a 30 V DC reverse voltage rating and 300 mA average rectified current per diode. The device is housed in a Surface Mount SC-70, SOT-323 package and features fast recovery characteristics with reverse recovery time ≤ 500 ns for currents > 200 mA.

The BAT30AWFILM is classified as Obsolete. Equivalent and substitute parts are necessary to maintain design continuity and ensure component availability for new production runs, repairs, and system upgrades. Substitute devices must maintain electrical compatibility across voltage, current, and thermal specifications while accommodating package and configuration variations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BAT30AWFILM is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Voltage - DC Reverse (Vr) (Max): Must equal or exceed 30 V
• Package / Case: Must be SC-70, SOT-323 or compatible surface mount package
• Diode Configuration: Common Anode configuration preferred for direct pin-compatible replacement
• Technology: Schottky diode technology
• Mounting Type: Surface Mount

Current Rating Consideration: The BAT30AWFILM operates at 300 mA per diode. Substitute parts rated at 200 mA per diode are acceptable for applications where the circuit design does not require the full 300 mA capability. However, designs dependent on 300 mA operation require substitutes with equivalent or higher current ratings.

Speed Characteristics: The BAT30AWFILM features fast recovery (≤ 500 ns for > 200 mA). Substitute parts with small signal speed characteristics (≤ 200 mA, any speed) are suitable for lower-current applications but may not satisfy fast recovery requirements in high-frequency switching circuits.

Thermal Specifications: Operating temperature range varies among substitutes. The BAT30AWFILM maximum junction temperature is 150°C. Substitutes with lower maximum junction temperatures (125°C) require thermal derating in high-temperature environments.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (SC-70, SOT-323 Package, Common Anode Configuration):

The following parts provide direct pin-compatible substitution with the BAT30AWFILM in SC-70, SOT-323 packages:

1PS70SB16,115 (Nexperia USA Inc.) and BAT54AWT1G (onsemi) are active production parts with Common Anode configuration matching the BAT30AWFILM. Both are rated at 200 mA per diode and 30 V reverse voltage. The 1PS70SB16,115 carries AEC-Q100 automotive qualification and is suitable for automotive-grade applications. The BAT54AWT1G provides equivalent electrical performance with active production status.

BAT54AW-7-F (Diodes Incorporated) is an active production alternative with Common Anode configuration in SC-70, SOT-323 package. This part is rated at 200 mA per diode and 30 V reverse voltage. The maximum junction temperature is 125°C, requiring thermal derating for applications exceeding this limit.

Secondary Substitute (Different Package):

BAT754A,215 (Nexperia USA Inc.) provides electrical equivalence with Common Anode configuration and 30 V, 200 mA ratings. This part is housed in TO-236-3, SC-59, SOT-23-3 package, which differs from the BAT30AWFILM SC-70, SOT-323 package. PCB layout modification is required for this substitution. The BAT754A,215 carries AEC-Q100 automotive qualification.

Alternative Configuration (Common Cathode):

1PS70SB15,115 (Nexperia USA Inc.) provides Common Cathode configuration with 30 V, 200 mA ratings in SC-70, SOT-323 package. This part requires circuit redesign to accommodate the different pin configuration. AEC-Q100 automotive qualification is provided.

Current Rating Limitation:

All substitute parts listed are rated at 200 mA per diode, compared to the BAT30AWFILM 300 mA rating. Applications requiring the full 300 mA capability must verify that circuit design operates within the 200 mA constraint or identify alternative parts with higher current ratings.

Compliance and Availability:

All substitute parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating, matching the BAT30AWFILM environmental compliance profile. All listed substitutes are in active production status with current inventory availability.

Frequently Asked Questions (FAQ)

Q: Can the 1PS70SB15,115 directly replace the BAT30AWFILM?

A: The 1PS70SB15,115 provides electrical equivalence in voltage and package but uses Common Cathode configuration instead of Common Anode. Direct pin-for-pin replacement is not possible. Circuit redesign is required to accommodate the different pin configuration.

Q: What is the impact of the 200 mA current rating on substitute parts compared to the BAT30AWFILM 300 mA rating?

A: The BAT30AWFILM is rated at 300 mA per diode, while all listed substitutes are rated at 200 mA per diode. Applications operating at currents exceeding 200 mA will exceed the substitute part ratings. Circuit design must be verified to ensure operation remains within the 200 mA limit, or alternative parts with higher current ratings must be identified.

Q: Are the BAT54AW-7-F and BAT54AWT1G interchangeable?

A: Both parts provide Common Anode configuration in SC-70, SOT-323 package with 30 V, 200 mA ratings. Electrical parameters are equivalent. The BAT54AW-7-F is manufactured by Diodes Incorporated, while BAT54AWT1G is manufactured by onsemi. Both are active production parts with current availability.

Q: Why does the BAT754A,215 require PCB layout modification?

A: The BAT754A,215 uses TO-236-3, SC-59, SOT-23-3 package, which differs from the BAT30AWFILM SC-70, SOT-323 package. The physical dimensions and pin spacing are different, requiring PCB footprint redesign and component placement adjustment.

Q: What is the significance of the 150°C maximum junction temperature in the BAT30AWFILM compared to 125°C in some substitutes?

A: The BAT30AWFILM operates at a higher maximum junction temperature (150°C) than some substitutes (125°C). Applications operating near or above 125°C require thermal derating of the substitute parts or verification that circuit design maintains junction temperature below the substitute part limit.

Q: Are all substitute parts automotive-qualified?

A: The 1PS70SB16,115 and BAT754A,215 carry AEC-Q100 automotive qualification. The BAT54AW-7-F and BAT54AWT1G do not list automotive qualification in the provided specifications. Automotive applications must verify qualification requirements with the component manufacturer.

Q: What is the difference between Fast Recovery and Small Signal speed classifications?

A: The BAT30AWFILM features Fast Recovery speed (≤ 500 ns for currents > 200 mA), suitable for high-frequency switching applications. Substitute parts with Small Signal speed classification (≤ 200 mA, any speed) are optimized for lower-current applications and may not satisfy fast recovery requirements in high-frequency circuits.

Q: Can the BAT30AWFILM be replaced with a part rated at lower reverse leakage current?

A: The BAT30AWFILM specifies 5 µA reverse leakage at 30 V. All listed substitutes specify 2 µA reverse leakage at 25 V, indicating lower leakage characteristics. Lower reverse leakage is generally acceptable and may improve circuit performance in applications sensitive to leakage current.

Q: What compliance certifications are common to all parts?

A: All parts listed are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. All parts are classified under ECCN EAR99 and HTSUS 8541.10.0070.
