Substitute Part Grouping Explanation

Substitute parts for the BAS70-06-V-GS18 are classified into two primary categories based on electrical and mechanical compatibility:

Category 1: Full Electrical and Mechanical Equivalents (200 mA Rating)

Parts in this category maintain identical or equivalent electrical specifications to the main part number, specifically the 200 mA average rectified current rating. These parts are interchangeable at the circuit level and differ only in packaging format (Tape & Reel versus Cut Tape) or minor manufacturing variations. The critical parameters for this category are:

Voltage - DC Reverse (Vr): 70 V
Current - Average Rectified (Io): 200 mA
Diode Configuration: 1 Pair Common Anode
Package / Case: TO-236-3, SC-59, SOT-23-3
Technology: Schottky

Category 2: Parametric Equivalents with Reduced Current Rating (70 mA Rating)

Parts in this category share the same reverse voltage rating (70 V), diode configuration, package format, and Schottky technology, but feature a reduced average rectified current rating of 70 mA per diode. These parts are suitable for applications with lower current requirements and may be used as substitutes only when circuit design permits operation within the 70 mA current limit. The critical parameters for this category are:

Voltage - DC Reverse (Vr): 70 V
Current - Average Rectified (Io): 70 mA
Diode Configuration: 1 Pair Common Anode
Package / Case: TO-236-3, SC-59, SOT-23-3
Technology: Schottky

Frequently Asked Questions (FAQ)

Q: Can BAS70-06-E3-18 be used as a direct replacement for BAS70-06-V-GS18?

A: Yes. Both parts maintain identical reverse voltage (70 V), current rating (200 mA), diode configuration (1 Pair Common Anode), package format (SOT-23-3), and maximum junction temperature (125°C). The primary difference is packaging format (Tape & Reel versus unspecified). Forward voltage is specified at different measurement points but both are within acceptable Schottky diode performance ranges.

Q: What is the difference between the 200 mA and 70 mA rated parts?

A: The 200 mA parts (BAS70-06-E3-18, BAS70-06-HE3-18, BAS70-06-E3-08, BAS70A-AU_R1_000A1) are rated for average rectified current of 200 mA per diode. The 70 mA parts (BAS70-06,215, BAS70-06-7-F, BAS70-06-TP, BAS70-06FILM, BAS7006E6327HTSA1, BAS7006E6433HTMA1) are rated for 70 mA per diode. Selection depends on circuit current requirements. The 70 mA parts cannot be used in applications requiring the full 200 mA capability.

Q: Are automotive-grade parts interchangeable with standard parts?

A: Automotive-grade parts (BAS70-06-HE3-18 with AEC-Q101, BAS70A-AU_R1_000A1 with AEC-Q101) meet additional qualification requirements and are suitable for automotive applications. Standard parts may be used in non-automotive applications. Automotive-grade parts can be used in standard applications but may not be cost-effective for non-automotive use.

Q: What does the packaging format designation mean?

A: Packaging format refers to how the component is supplied. Tape & Reel (TR) format is used for high-volume automated assembly. Cut Tape (CT) format is used for lower-volume or manual assembly. Digi-Reel® is a proprietary reel format. The electrical specifications remain identical regardless of packaging format.

Q: Can I substitute a part with a higher maximum junction temperature?

A: Yes. Parts with higher maximum junction temperature ratings (150°C versus 125°C) can be used in applications designed for lower temperature ratings. The higher rating provides additional thermal margin. However, this does not change the electrical performance or current-carrying capability of the device.

Q: What is the significance of reverse recovery time (trr)?

A: Reverse recovery time is the time required for the diode to switch from forward conduction to reverse blocking. Faster recovery times (5 ns or 100 ps) result in lower switching losses and reduced electromagnetic interference. Parts with 100 ps recovery time (Infineon BAS7006 series) offer superior high-frequency performance compared to parts with 5 ns recovery time.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All parts listed in this reference maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity level, ensuring compatibility with modern manufacturing processes and environmental regulations.

Q: What is the difference between forward voltage specifications at different measurement points?

A: Forward voltage varies with measurement current. The main part specifies 410 mV @ 1 mA, while some substitutes specify 1 V @ 15 mA. Both specifications are valid for Schottky diodes. The higher voltage at higher current reflects the diode's I-V characteristic curve. Selection should be based on circuit operating point requirements.
