Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the BAS28Q-13 are identified based on strict electrical and mechanical parameter matching. The substitution logic is based on the following critical parameters:

Electrical Parameters:

• Diode configuration (2 Independent)
• Maximum reverse voltage (85V)
• Average rectified current per diode (215mA DC)
• Forward voltage at specified current (1.25V @ 150mA)
• Fast recovery speed characteristics (≤500ns, >200mA)
• Reverse recovery time (4ns)
• Reverse leakage current (1µA @ 75V)
• Operating temperature range (-65°C to 150°C)

Mechanical Parameters:

• Package type (TO-253-4, TO-253AA)
• Supplier device package (SOT-143)
• Surface mount mounting type

Compliance Parameters:

• Automotive grade classification
• RoHS3 compliance
• Moisture sensitivity level (MSL 1)

Parts meeting all these parameters are classified as parametric equivalents and direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

Both the BAS28Q-13 and BAS28-7 are Active products manufactured by Diodes Incorporated with identical electrical and mechanical specifications. The parts are fully interchangeable from a functional standpoint, with all critical parameters matching across voltage ratings, current handling, thermal characteristics, and package specifications.

The primary distinction between these parts is the automotive qualification standard: BAS28Q-13 carries AEC-Q100 qualification, while BAS28-7 carries AEC-Q101 qualification. Both standards represent automotive-grade reliability certifications. Selection between these parts should be based on specific project qualification requirements and supply chain availability.

Both parts maintain RoHS3 compliance, MSL 1 rating, and are suitable for surface mount assembly in TO-253-4 and TO-253AA packages. The identical electrical performance ensures direct substitution without circuit redesign or re-qualification of electrical characteristics.

Frequently Asked Questions (FAQ)

Q: Can BAS28-7 be used as a direct replacement for BAS28Q-13?

A: Yes. Both parts share identical electrical specifications including reverse voltage (85V), rectified current (215mA), forward voltage (1.25V @ 150mA), recovery time (4ns), and operating temperature range (-65°C to 150°C). The parts are mechanically compatible in TO-253-4 and TO-253AA packages with SOT-143 supplier packaging.

Q: What is the difference between AEC-Q100 and AEC-Q101 qualifications?

A: Both are automotive-grade reliability qualifications. AEC-Q100 and AEC-Q101 represent different qualification pathways established by the Automotive Electronics Council. Selection depends on specific project qualification requirements and customer specifications.

Q: Are the parts pin-compatible?

A: Yes. Both BAS28Q-13 and BAS28-7 use the same TO-253-4 and TO-253AA package configurations with identical pinouts for the 2 independent diode array configuration.

Q: What is the significance of MSL 1 (Unlimited) rating?

A: MSL 1 indicates the lowest moisture sensitivity level, meaning the component has unlimited shelf life under standard storage conditions without requiring special moisture control or baking procedures prior to assembly.

Q: Can these parts be used interchangeably in automotive applications?

A: Yes. Both parts carry automotive-grade classification and are RoHS3 compliant. They meet the electrical and thermal requirements for automotive rectification circuits. Selection should align with project-specific qualification documentation.

Q: What is the base product number relationship?

A: Both BAS28Q-13 and BAS28-7 share the base product number BAS28, indicating they are variants within the same product family with identical core electrical specifications.
