Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BAW56-G is determined by the following critical parameters:

Configuration Match: All substitute parts must maintain 1 Pair Common Anode diode configuration to ensure pin-level compatibility.

Package Match: All substitute parts must use TO-236-3, SC-59, or SOT-23-3 surface mount packaging to ensure mechanical and electrical compatibility with existing PCB layouts.

Voltage Rating: Substitute parts must have DC reverse voltage (Vr) rating equal to or greater than 70 V to maintain circuit protection margins.

Current Rating: Substitute parts must have average rectified current (Io) rating equal to or greater than 215 mA per diode to support circuit load requirements.

Speed Characteristics: Substitute parts must maintain Fast Recovery classification (≤500 ns, >200 mA) to preserve switching performance.

Compliance: All substitute parts must maintain ROHS3 compliance and Unlimited MSL rating to ensure manufacturing and storage compatibility.

The BAW56-7-F and BAW56-TP both satisfy these substitution criteria with equal or superior electrical ratings and identical packaging specifications.

Parameter Comparison

Engineering Selection Recommendations

BAW56-7-F (Diodes Incorporated): This substitute provides superior electrical performance with 75 V reverse voltage rating and 300 mA current capacity, exceeding BAW56-G specifications. Reverse recovery time is reduced to 4 ns. Operating temperature range extends to -65°C. All compliance certifications match the original part. This substitute is suitable for applications requiring enhanced voltage and current margins.

BAW56-TP (Micro Commercial Co): This substitute provides 75 V reverse voltage rating and 250 mA current capacity, exceeding BAW56-G specifications. Reverse recovery time is 4 ns. Forward voltage measurement is specified at different test conditions (855 mV @ 10 mA versus 1.25 V @ 150 mA). Operating temperature range matches the original part at -55°C to 150°C. All compliance certifications match the original part. This substitute is suitable for applications requiring moderate voltage and current margin improvements.

Both substitutes maintain Active product status and full ROHS3 compliance with Unlimited MSL rating, ensuring manufacturing and supply chain compatibility with the original BAW56-G specification.

Frequently Asked Questions (FAQ)

Q: Can BAW56-7-F replace BAW56-G in all applications?

A: Yes. The BAW56-7-F maintains identical diode configuration (1 Pair Common Anode), identical package (SOT-23-3), and identical mounting type (Surface Mount). Electrical ratings are equal or superior: 75 V reverse voltage versus 70 V, 300 mA current versus 215 mA, and 4 ns reverse recovery time versus 6 ns. All compliance certifications are equivalent.

Q: Can BAW56-TP replace BAW56-G in all applications?

A: Yes. The BAW56-TP maintains identical diode configuration (1 Pair Common Anode), identical package (SOT-23-3), and identical mounting type (Surface Mount). Electrical ratings are equal or superior: 75 V reverse voltage versus 70 V and 250 mA current versus 215 mA. Reverse recovery time is 4 ns versus 6 ns. All compliance certifications are equivalent.

Q: What is the primary difference between BAW56-7-F and BAW56-TP?

A: Both substitutes provide 75 V reverse voltage and superior reverse recovery time (4 ns). The BAW56-7-F provides higher current capacity at 300 mA versus 250 mA for the BAW56-TP. The BAW56-7-F also extends the operating temperature range to -65°C versus -55°C for the BAW56-TP. Forward voltage specifications are measured at different test conditions between the two parts.

Q: Are all three parts pin-compatible?

A: Yes. All three parts use identical SOT-23-3 package configuration with 1 Pair Common Anode diode arrangement, ensuring direct pin-level compatibility on PCB layouts designed for BAW56-G.

Q: Do the substitute parts maintain RoHS3 compliance?

A: Yes. Both BAW56-7-F and BAW56-TP are ROHS3 compliant with Unlimited MSL rating, matching the original BAW56-G specification.

Q: What is the significance of reverse recovery time differences?

A: Reverse recovery time (trr) measures the speed at which a diode transitions from forward conduction to reverse blocking. The BAW56-7-F and BAW56-TP both provide 4 ns recovery time versus 6 ns for the BAW56-G, indicating faster switching transitions. This improvement is beneficial in high-frequency switching applications but does not prevent substitution in standard applications.

Q: Can BAW56-G be used in place of BAW56-7-F or BAW56-TP?

A: No. The BAW56-G has lower voltage (70 V versus 75 V) and lower current (215 mA versus 250-300 mA) ratings. Using a lower-rated component in place of a higher-rated specification may result in insufficient circuit protection or performance degradation.
