BAT41JFILM Equivalent & Substitute Parts

Part Overview

The BAT41JFILM is a Schottky diode manufactured by STMicroelectronics, rated for 100 V DC reverse voltage and 200 mA average rectified current in a surface mount SOD-323 package. This component is classified as obsolete, necessitating identification of equivalent substitute parts for ongoing design requirements and procurement needs. Substitute parts must maintain electrical and mechanical compatibility within the specified parameter ranges.

Substitute Part Grouping Explanation

Substitute parts for the BAT41JFILM are selected based on the following electrical and mechanical criteria:

Primary Substitution Criteria:

Voltage - DC Reverse (Vr) (Max): Equal to or greater than 100 V
Current - Average Rectified (Io): Equal to or greater than 200 mA
Package / Case: SOD-323 (SC-76)
Mounting Type: Surface Mount
Technology: Schottky diode

Acceptable Substitutes:

The BAT46JFILM meets all primary criteria with identical reverse voltage (100 V) and package specification (SOD-323). Although the average rectified current is rated at 150 mA (lower than the 200 mA specification of the BAT41JFILM), this part is listed as an acceptable substitute in the provided data.

The 1N5711WS-7-F does not meet the primary substitution criteria. The peak reverse voltage is 70 V (below the 100 V requirement), and the maximum current is 15 mA (significantly below the 200 mA requirement). This part is included in the substitute list but operates outside the specified electrical parameters of the BAT41JFILM.

Engineering Selection Recommendations

BAT46JFILM is the primary substitute for the BAT41JFILM. Both parts are manufactured by STMicroelectronics, share identical reverse voltage ratings (100 V), and use the same SOD-323 package. The BAT46JFILM is currently in active production status, ensuring availability and supply chain continuity. Both parts maintain ROHS3 compliance and unlimited moisture sensitivity classification. The BAT46JFILM is suitable for applications where the 150 mA current rating is acceptable within the circuit design parameters.

1N5711WS-7-F is listed as a substitute but operates outside the primary electrical specifications of the BAT41JFILM. The 70 V reverse voltage rating and 15 mA maximum current are significantly lower than the BAT41JFILM requirements. This part is suitable only for applications with reduced voltage and current demands. The 1N5711WS-7-F is manufactured by Diodes Incorporated and maintains active product status with ROHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can the BAT46JFILM directly replace the BAT41JFILM in all applications?

A: The BAT46JFILM shares the same reverse voltage rating (100 V) and package specification (SOD-323) as the BAT41JFILM. The primary difference is the average rectified current rating: 150 mA versus 200 mA. Direct substitution is valid only if the circuit design operates within the 150 mA current limit.

Q: What are the key differences between BAT46JFILM and 1N5711WS-7-F?

A: The BAT46JFILM maintains 100 V reverse voltage and 150 mA current capability. The 1N5711WS-7-F is rated for 70 V reverse voltage and 15 mA maximum current. These represent different performance classes. The 1N5711WS-7-F is suitable for lower-voltage, lower-current applications only.

Q: Are all substitute parts available in the same package?

A: Yes. The BAT41JFILM, BAT46JFILM, and 1N5711WS-7-F are all supplied in the SOD-323 package (SC-76), enabling mechanical compatibility in surface mount applications.

Q: What is the compliance status of these substitute parts?

A: All three parts are ROHS3 compliant, REACH unaffected, and classified as ECCN EAR99. All parts maintain MSL 1 (Unlimited) moisture sensitivity classification.

Q: Why is the BAT41JFILM listed as obsolete?

A: The BAT41JFILM is classified as obsolete by STMicroelectronics. The BAT46JFILM, also from STMicroelectronics, is the active product line replacement and is currently in production.

Q: What is the operating temperature range difference between these parts?

A: The BAT41JFILM and BAT46JFILM both support maximum junction temperatures of 150°C. The 1N5711WS-7-F supports a maximum junction temperature of 125°C, representing a 25°C reduction in thermal capability.
