Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the BAS70-04Q-13-F are classified into two categories based on electrical parameter alignment:

Parametric Equivalents maintain identical electrical specifications across all critical parameters: 70 V reverse voltage, 70 mA average rectified current, 1 V forward voltage at 15 mA, 5 ns reverse recovery time, and -55°C to 125°C operating temperature range. These parts differ only in packaging format (Cut Tape vs. Tape & Reel) or manufacturer source while preserving the same functional performance. Parametric equivalents include BAS70-04-7-F (Diodes Incorporated, Cut Tape & Digi-Reel), BAS70-04 RFG (Taiwan Semiconductor Corporation, Tape & Reel), and BAS70-04-TP (Micro Commercial Co, Tape & Reel).

Similar Parts share the same package footprint, diode configuration, and reverse voltage rating but differ in one or more electrical parameters. The BAS70S-AU_R1_000A1 (Panjit International Inc.) operates at 200 mA average rectified current per diode with a forward voltage of 900 mV at 15 mA and extends the operating temperature range to -55°C to 150°C. This part is suitable for applications requiring higher current capacity within the same voltage class and package envelope.

All substitute parts maintain surface mount SOT-23-3 package compatibility, automotive-grade qualification, AEC-Q101 certification, and ROHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Parametric Equivalents):

BAS70-04-7-F, BAS70-04 RFG, and BAS70-04-TP are parametric equivalents suitable for direct substitution in applications where the BAS70-04Q-13-F is specified. These parts maintain identical electrical performance across voltage, current, and thermal parameters. Selection among these three equivalents is determined by packaging format availability and supply chain requirements. BAS70-04-7-F is available in Cut Tape and Digi-Reel format, while BAS70-04 RFG and BAS70-04-TP are supplied in Tape & Reel format. All three maintain ROHS3 compliance and unlimited moisture sensitivity level (MSL 1).

For Higher Current Applications:

BAS70S-AU_R1_000A1 is classified as a similar part suitable for applications requiring increased current capacity. This part supports 200 mA average rectified current per diode compared to 70 mA in the main part, while maintaining the same 70 V reverse voltage rating and SOT-23-3 package footprint. The forward voltage is reduced to 900 mV at 15 mA, and the operating temperature range extends to 150°C. This part carries automotive-grade qualification and AEC-Q101 certification, matching the compliance profile of the main part. BAS70S-AU_R1_000A1 is appropriate for designs where thermal performance or current handling requirements exceed the specifications of the 70 mA rated parts.

Compliance Considerations:

All substitute parts maintain ROHS3 compliance and REACH unaffected status. The main part and BAS70S-AU_R1_000A1 carry explicit automotive-grade designation and AEC-Q101 qualification. For applications requiring automotive qualification, BAS70S-AU_R1_000A1 is the only similar part with matching certification. Parametric equivalents do not specify automotive grade or AEC-Q101 qualification in the provided data.

Frequently Asked Questions (FAQ)

Q: Can BAS70-04-7-F be used as a direct replacement for BAS70-04Q-13-F?

A: Yes. BAS70-04-7-F is a parametric equivalent with identical electrical specifications: 70 V reverse voltage, 70 mA average rectified current, 1 V forward voltage at 15 mA, 5 ns reverse recovery time, and -55°C to 125°C operating temperature. The only difference is packaging format (Cut Tape & Digi-Reel vs. Tape & Reel). Both parts are ROHS3 compliant and maintain the same SOT-23-3 package footprint.

Q: What is the difference between BAS70-04 RFG and BAS70-04-TP?

A: Both are parametric equivalents with identical electrical specifications to the main part. The primary differences are manufacturer source (Taiwan Semiconductor Corporation vs. Micro Commercial Co) and reverse leakage current specification (100 nA @ 50 V vs. 200 nA @ 50 V). BAS70-04-TP extends the operating temperature range to 150°C compared to 125°C for BAS70-04 RFG. Both are supplied in Tape & Reel format and maintain ROHS3 compliance.

Q: When should BAS70S-AU_R1_000A1 be selected instead of parametric equivalents?

A: BAS70S-AU_R1_000A1 is selected for applications requiring higher current capacity. This part supports 200 mA average rectified current per diode, compared to 70 mA in parametric equivalents. The forward voltage is lower at 900 mV, and the operating temperature range extends to 150°C. This part is suitable for designs where thermal performance or current handling requirements exceed 70 mA specifications while maintaining the same 70 V voltage rating and SOT-23-3 package compatibility.

Q: Are all substitute parts automotive-qualified?

A: The main part BAS70-04Q-13-F and BAS70S-AU_R1_000A1 carry explicit automotive-grade designation and AEC-Q101 qualification. The parametric equivalents BAS70-04-7-F, BAS70-04 RFG, and BAS70-04-TP do not specify automotive grade or AEC-Q101 qualification in the provided specifications. For applications requiring automotive qualification, BAS70S-AU_R1_000A1 is the only similar part with matching certification.

Q: Do all substitute parts use the same package footprint?

A: Yes. All substitute parts use the SOT-23-3 package (also designated TO-236-3 or SC-59). The package footprint is identical across all parts, enabling direct board-level substitution. Differences exist only in packaging format for component delivery (Cut Tape, Digi-Reel, or Tape & Reel).

Q: What is the reverse leakage current difference between substitute parts?

A: The main part BAS70-04Q-13-F specifies 100 nA @ 50 V. BAS70-04-7-F and BAS70-04 RFG maintain this specification. BAS70-04-TP specifies 200 nA @ 50 V, which is twice the leakage current. BAS70S-AU_R1_000A1 specifies 1 µA @ 70 V, which is significantly higher. For applications sensitive to leakage current, parametric equivalents with 100 nA specification are preferred.

Q: Can parametric equivalents be mixed in the same design?

A: Yes. BAS70-04-7-F, BAS70-04 RFG, and BAS70-04-TP are parametric equivalents with identical electrical specifications. They can be used interchangeably in the same circuit design. Selection is based on packaging format availability and supply chain requirements rather than electrical performance differences.
