Key Parameters

Substitute Part Grouping Explanation

Substitution of the BAT54SW-7-F-79 is determined by electrical and mechanical parameter equivalence across the following critical specifications:

Electrical Parameters:

• Diode Configuration: 1 Pair Series Connection
• Technology: Schottky
• Voltage - DC Reverse (Vr) (Max): 30 V
• Current - Average Rectified (Io) (per Diode): 200 mA (DC)
• Voltage - Forward (Vf) (Max) @ If: 1 V @ 100 mA
• Reverse Recovery Time (trr): 5 ns
• Current - Reverse Leakage @ Vr: 2 µA @ 25 V

Mechanical Parameters:

• Package / Case: SC-70, SOT-323
• Mounting Type: Surface Mount

Compliance Parameters:

• RoHS Status: ROHS3 Compliant

Frequently Asked Questions (FAQ)

Q: Can BAT54SW-7-F be used as a direct replacement for BAT54SW-7-F-79?

A: Yes. The BAT54SW-7-F is a direct parametric equivalent with identical electrical specifications (30 V reverse voltage, 200 mA current rating, 1 V forward voltage at 100 mA, 5 ns reverse recovery time) and mechanical specifications (SC-70, SOT-323 package, surface mount). The primary difference is product status: BAT54SW-7-F is Active while BAT54SW-7-F-79 is Obsolete.

Q: What is the difference between BAT54SWQ-7-F and BAT54SW-7-F?

A: Both parts are electrically and mechanically equivalent. The BAT54SWQ-7-F includes AEC-Q101 automotive qualification and Automotive grade designation, making it suitable for automotive applications requiring enhanced reliability standards. Standard applications can use either part.

Q: Are all substitute parts compatible with the same PCB layout?

A: Yes. All substitute parts use the SC-70, SOT-323 package with surface mount configuration. PCB footprints, land patterns, and assembly processes remain identical across all listed substitutes.

Q: Does operating temperature range affect substitution?

A: Operating temperature range does not affect functional substitution within the specified electrical parameter envelope. The BAT54SW-7-F-79 operates from -65°C to 125°C. Substitute parts operate within -55°C to 125°C (BAT54SWT-TP) or -65°C to 125°C (BAT54SW-7-F, BAT54SWQ-7-F) ranges. All substitutes cover the standard industrial temperature range and are suitable for equivalent applications.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts listed carry ROHS3 Compliant status with Moisture Sensitivity Level 1 (Unlimited), matching the compliance profile of the BAT54SW-7-F-79.
