BAS70L2-TP Equivalent & Substitute Parts

Part Overview

The BAS70L2-TP is a Schottky diode manufactured by Micro Commercial Co, rated for 70 V DC reverse voltage and 70 mA average rectified current in a surface mount DFN1006-2L (0402 metric) package. This component is classified as a small signal Schottky rectifier diode with a reverse recovery time of 5 ns, suitable for high-speed switching applications requiring low forward voltage drop.

The part is currently in active production status with RoHS3 compliance and unlimited moisture sensitivity level (MSL 1). Substitute parts are identified based on matching electrical performance parameters within the small signal diode category, allowing for package and manufacturer variation while maintaining functional equivalence in circuit applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BAS70L2-TP is determined by electrical parameter matching within the Schottky diode rectifier category. The primary substitution criteria are:

Electrical Equivalence Parameters:

• Voltage - DC Reverse (Vr) (Max): 70 V
• Current - Average Rectified (Io): 70 mA
• Technology: Schottky
• Speed Classification: Small Signal ≤ 200mA (Io), Any Speed

Compliance & Environmental Parameters:

• RoHS3 Compliance: Required
• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• REACH Status: REACH Unaffected
• Operating Temperature Range: Minimum -55°C to 125°C

Package Considerations: Substitute parts may utilize different surface mount packages (DFN1006-2L, SOD-923) provided the electrical ratings and compliance certifications remain equivalent. Package selection depends on circuit board layout and assembly process compatibility.

The identified substitute NSR0170P2T5G by onsemi meets all electrical equivalence criteria and compliance requirements, with variation in forward voltage characteristics and reverse leakage current within acceptable engineering tolerances for this diode category.

Engineering Selection Recommendations

Primary Selection: BAS70L2-TP

The BAS70L2-TP remains the primary component choice when DFN1006-2L (0402 metric) package compatibility is required. This part is in active production with full RoHS3 compliance and MSL 1 rating. The forward voltage specification of 1 V @ 15 mA provides the lowest forward drop among available options in this electrical class.

Substitute Selection: NSR0170P2T5G

The NSR0170P2T5G by onsemi is a qualified electrical equivalent when SOD-923 package compatibility is acceptable. This substitute maintains identical voltage and current ratings (70 V, 70 mA) and identical capacitance characteristics (2 pF @ 0V, 1MHz). Both parts are active production items with ROHS3 compliance and MSL 1 rating.

Compliance Verification:

Both the primary part and substitute meet the following compliance requirements:

• RoHS3 Compliant
• REACH Unaffected
• ECCN: EAR99
• HTSUS: 8541.10.0070

Temperature Operating Range:

The NSR0170P2T5G provides an extended maximum junction temperature of 150°C compared to the BAS70L2-TP at 125°C. Both parts maintain the same minimum operating temperature of -55°C.

Frequently Asked Questions (FAQ)

Q: What are the primary electrical criteria for substituting the BAS70L2-TP?

A: The BAS70L2-TP can be substituted with parts meeting these electrical specifications: 70 V DC reverse voltage rating, 70 mA average rectified current, Schottky technology, and small signal speed classification (≤ 200mA). All substitute parts must maintain RoHS3 compliance and MSL 1 rating.

Q: How do the forward voltage characteristics differ between BAS70L2-TP and NSR0170P2T5G?

A: The BAS70L2-TP specifies a maximum forward voltage of 1 V @ 15 mA, while the NSR0170P2T5G specifies 730 mV @ 15 mA. The NSR0170P2T5G exhibits lower forward voltage drop. Both values are within acceptable operating parameters for small signal Schottky diodes in this voltage and current class.

Q: Can the NSR0170P2T5G be used as a direct replacement in existing PCB layouts designed for BAS70L2-TP?

A: No. The BAS70L2-TP uses a DFN1006-2L (0402 metric) package, while the NSR0170P2T5G uses an SOD-923 package. These packages have different footprints and pin configurations. PCB layout modification is required for package substitution.

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

A: The BAS70L2-TP specifies 200 nA @ 50 V reverse leakage, while the NSR0170P2T5G specifies 3 µA @ 70 V. The BAS70L2-TP exhibits lower reverse leakage current. This difference is characteristic of different manufacturing processes and does not prevent functional substitution in most applications.

Q: Are both parts suitable for high-speed switching applications?

A: Yes. Both the BAS70L2-TP and NSR0170P2T5G are classified as small signal Schottky diodes with fast switching characteristics. The BAS70L2-TP specifies a reverse recovery time of 5 ns. Both parts are suitable for high-speed switching applications within their rated voltage and current specifications.

Q: What is the operating temperature range difference between these parts?

A: The BAS70L2-TP operates from -55°C to 125°C junction temperature. The NSR0170P2T5G operates from -55°C to 150°C junction temperature. The NSR0170P2T5G provides a 25°C higher maximum operating temperature, which may be beneficial in high-temperature environments.

Q: Do both parts have identical capacitance characteristics?

A: Yes. Both the BAS70L2-TP and NSR0170P2T5G specify 2 pF capacitance @ 0V, 1MHz. This identical capacitance rating ensures equivalent performance in high-frequency applications and timing-sensitive circuits.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both parts are RoHS3 compliant, REACH unaffected, and carry the same ECCN (EAR99) and HTSUS (8541.10.0070) classifications. Both maintain MSL 1 (unlimited) moisture sensitivity level. Compliance requirements are identical.
