BAW 56W H6327 Equivalent & Substitute Parts

Part Overview

The BAW 56W H6327 is a general-purpose diode array manufactured by Infineon Technologies, configured as a 1 Pair Common Anode with 80 V DC reverse voltage rating and 200 mA average rectified current per diode. The device is housed in a surface mount SC-70, SOT-323 package and is classified as obsolete. Due to its obsolete product status, equivalent and substitute parts from active manufacturers are necessary to maintain design continuity and ensure long-term component availability for new production and redesign efforts.

Substitute Part Grouping Explanation

Substitution of the BAW 56W H6327 is determined by the following critical parameters: diode configuration (1 Pair Common Anode), maximum DC reverse voltage rating, average rectified current per diode, forward voltage characteristics, reverse recovery time, and surface mount package compatibility. Substitute parts must maintain electrical equivalence within the specified operating ranges and physical compatibility with the original SC-70, SOT-323 footprint or compatible surface mount packages.

The substitute parts listed below are grouped based on their ability to meet or exceed the electrical requirements of the original BAW 56W H6327 while maintaining the same diode configuration and mounting technology. Parts with higher voltage or current ratings provide direct substitution capability. Parts with lower current ratings require application-level verification of current requirements but remain electrically compatible for lower-current applications.

Frequently Asked Questions (FAQ)

Q: Can the 1PS300,115 directly replace the BAW 56W H6327 in all applications?

A: The 1PS300,115 maintains the same 80 V reverse voltage rating and SC-70, SOT-323 package footprint. However, its 170 mA current rating is lower than the original 200 mA specification. Direct replacement is possible only in applications where the actual operating current does not exceed 170 mA. Circuit-level current analysis is required to confirm compatibility.

Q: Why does the BAW56-7-F have a different package designation (SOT-23-3 vs. SOT-323)?

A: The BAW56-7-F uses a TO-236-3, SC-59, SOT-23-3 package, which differs from the original SC-70, SOT-323 package. While both are surface mount packages with similar pin counts, the physical footprints are different. PCB layout modifications are necessary if this substitute is selected. The electrical characteristics remain compatible.

Q: What is the significance of the higher voltage ratings in BAW56W,115 and BAW56W,135?

A: Both parts provide 90 V reverse voltage ratings compared to the original 80 V specification. This higher voltage rating provides additional design margin and allows operation in circuits with higher reverse voltage stress. However, both parts have reduced current capacity (150 mA vs. 200 mA), which may limit their use in higher-current applications.

Q: Are all substitute parts automotive-qualified?

A: The 1PS300,115, BAW56W,115, and BAW56W,135 are AEC-Q101 qualified for automotive applications. The BAW56-7-F and BAW56W-7-F do not specify automotive qualification in the provided data. Selection should consider application requirements and qualification standards.

Q: What is the difference between BAW56W,115 and BAW56W,135?

A: Both parts have identical electrical specifications: 90 V reverse voltage, 150 mA current, and SC-70, SOT-323 package. The primary difference is packaging format: BAW56W,115 is supplied in Cut Tape (CT) & Digi-Reel format, while BAW56W,135 is supplied in Bulk. Both are active products from different manufacturers (Nexperia USA Inc. and NXP Semiconductors, respectively).

Q: Can I use a substitute part with lower current rating if my circuit only draws 150 mA?

A: Yes, substitute parts with 150 mA ratings (BAW56W,115, BAW56W,135, BAW56W-7-F) are suitable for applications where the actual operating current does not exceed 150 mA. The current rating must equal or exceed the maximum current the circuit will draw under all operating conditions, including transient events.

Q: What does MSL 1 (Unlimited) mean for moisture sensitivity?

A: MSL 1 (Unlimited) indicates that the component has unlimited shelf life and does not require special moisture control during storage or handling. All listed parts and the original BAW 56W H6327 share this MSL classification, ensuring consistent handling requirements across all options.

Q: Are all substitute parts RoHS compliant?

A: The 1PS300,115, BAW56-7-F, and BAW56W-7-F are explicitly ROHS3 compliant. The BAW56W,115 and BAW56W,135 do not specify RoHS status in the provided data. For applications requiring RoHS compliance, verification with the manufacturer is recommended for BAW56W,115 and BAW56W,135.
