BAW56T-TP Equivalent & Substitute Parts

Part Overview

The BAW56T-TP is a general-purpose diode array manufactured by Micro Commercial Co, configured as a 1 Pair Common Anode device in SOT-523 surface mount packaging. This component is rated for 85 V DC reverse voltage and 75 mA average rectified current per diode, with a maximum forward voltage of 1 V at 50 mA. The part is Active in product status and ROHS3 compliant. Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and design continuity when the primary part becomes unavailable or when alternative electrical characteristics better suit specific application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the BAW56T-TP are classified into two categories based on electrical and mechanical compatibility:

Parametric Equivalent: Parts that match the primary electrical specifications (85 V reverse voltage, 75 mA average rectified current, 1 V forward voltage at 50 mA, 4 ns reverse recovery time) and use identical SOT-523 packaging. These parts are direct functional replacements with no circuit redesign required.

Similar Substitute: Parts that maintain the 1 Pair Common Anode configuration and common base product series (BAW56) but operate at different voltage and current ratings (70 V reverse voltage, 200 mA average rectified current). These parts use alternative surface mount packaging (SC-75, SOT-416) and exhibit different electrical characteristics. Selection of similar substitutes requires verification that the application can tolerate the specified parameter differences.

The substitution logic is based strictly on:

• Diode configuration (1 Pair Common Anode)
• Reverse voltage rating compatibility
• Average rectified current capacity
• Forward voltage characteristics
• Package type and mounting compatibility
• Operating temperature range
• Compliance certifications (ROHS3, REACH)

Parameter Comparison

Engineering Selection Recommendations

BAW56T-7-F (Parametric Equivalent - Diodes Incorporated): This part is the preferred parametric equivalent for direct substitution. It matches all critical electrical specifications of the BAW56T-TP, including 85 V reverse voltage, 75 mA average rectified current, 1 V forward voltage at 50 mA, and 4 ns reverse recovery time. Both parts use identical SOT-523 packaging, enabling direct board-level replacement without circuit modification. The BAW56T-7-F offers an extended lower operating temperature range (-65°C to 150°C versus -55°C to 150°C), providing additional thermal margin in cold-environment applications. All compliance certifications (ROHS3, REACH) are equivalent. Inventory availability is 16,170 pieces.

BAW56TT1G (Similar Substitute - onsemi): This part shares the common anode configuration and BAW56 base product series but operates at reduced reverse voltage (70 V) and elevated average rectified current (200 mA). The forward voltage is higher at 1.25 V @ 150 mA, and reverse recovery time is longer at 6 ns. The package differs (SC-75, SOT-416 versus SOT-523), requiring PCB layout modification. This substitute is applicable only when the application circuit can tolerate the lower voltage rating and higher current capacity does not introduce thermal or noise concerns. All compliance certifications are equivalent. Inventory availability is 17,200 pieces.

Selection between these parts depends on circuit requirements: use BAW56T-7-F for direct replacement; use BAW56TT1G only when electrical parameter differences and package change are acceptable to the design.

Frequently Asked Questions (FAQ)

Q: Can BAW56T-7-F be used as a direct replacement for BAW56T-TP without PCB modification?

A: Yes. The BAW56T-7-F is a parametric equivalent with identical electrical specifications (85 V, 75 mA, 1 V forward voltage, 4 ns recovery time) and uses the same SOT-523 package. No circuit redesign or board layout changes are required.

Q: What are the key differences between BAW56TT1G and BAW56T-TP?

A: The BAW56TT1G operates at 70 V reverse voltage (versus 85 V), supports 200 mA average rectified current (versus 75 mA), exhibits 1.25 V forward voltage at 150 mA (versus 1 V at 50 mA), and uses SC-75/SOT-416 packaging (versus SOT-523). These differences require application-level verification before substitution.

Q: Are all three parts ROHS3 compliant?

A: Yes. BAW56T-TP, BAW56TT1G, and BAW56T-7-F are all ROHS3 compliant with MSL rating of 1 (Unlimited) and REACH Unaffected status.

Q: What is the impact of the 6 ns reverse recovery time in BAW56TT1G compared to 4 ns in BAW56T-TP?

A: The longer reverse recovery time (6 ns versus 4 ns) in BAW56TT1G may affect switching speed in high-frequency applications. Applications operating at frequencies where this 2 ns difference is significant should retain BAW56T-TP or use BAW56T-7-F.

Q: Can BAW56TT1G be used in a circuit designed for 85 V operation?

A: No. BAW56TT1G is rated for 70 V maximum reverse voltage. Using it in an 85 V circuit exceeds its voltage rating and risks component failure. The circuit must be verified to operate within 70 V limits before substitution.

Q: Does the extended temperature range of BAW56T-7-F (-65°C to 150°C) provide any advantage?

A: Yes. The BAW56T-7-F supports operation down to -65°C, compared to -55°C for BAW56T-TP. This provides 10°C additional margin in cold-environment or aerospace applications. For standard industrial temperature ranges, both parts are equivalent.

Q: What inventory quantities are available for each part?

A: BAW56T-TP: 830 pieces; BAW56TT1G: 17,200 pieces; BAW56T-7-F: 16,170 pieces. Availability may influence procurement decisions when lead times are critical.
