BAS70-05-HF Equivalent & Substitute Parts

Part Overview

The BAS70-05-HF is a Schottky diode array manufactured by Comchip Technology, configured as 1 pair common cathode with a maximum reverse voltage rating of 70 V and average rectified current of 70 mA per diode. The device is housed in a SOT-23-3 surface mount package and is classified as Active product status. Substitute parts are identified when equivalent electrical characteristics and mechanical compatibility are required due to component availability, supply chain considerations, or design flexibility across multiple qualified manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BAS70-05-HF is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Diode configuration: 1 Pair Common Cathode
• Technology: Schottky
• Maximum reverse voltage: 70 V
• Average rectified current per diode: 70 mA (DC)
• Forward voltage: 1 V @ 15 mA
• Reverse recovery time: 5 ns
• Operating temperature range: -55°C ~ 125°C

Mechanical Equivalence Criteria:

• Package type: TO-236-3, SC-59, SOT-23-3
• Mounting type: Surface Mount

Compliance Criteria:

• RoHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

All substitute parts listed maintain identical electrical performance and mechanical compatibility with the BAS70-05-HF across these parameters. Variations in reverse leakage current (100 nA vs. 200 nA @ 50 V) and packaging format (Tape & Reel vs. Cut Tape) do not affect functional substitution.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain Active product status and full ROHS3 compliance with MSL 1 (Unlimited) rating, ensuring long-term availability and environmental regulatory adherence. Selection between the BAS70-05-HF and its substitutes is based on:

Manufacturer Availability: BAS70-05-TP (Micro Commercial Co) offers the highest inventory level at 248,307 pieces, providing supply chain flexibility. BAS70-05-7-F (Diodes Incorporated) provides 8,184 pieces with Cut Tape and Digi-Reel packaging options. BAS70-05 RFG (Taiwan Semiconductor Corporation) supplies 7,090 pieces. The primary BAS70-05-HF maintains 984 pieces in stock.

Packaging Format: BAS70-05-HF and BAS70-05 RFG are supplied in Tape & Reel format. BAS70-05-7-F is available in Cut Tape and Digi-Reel format. BAS70-05-TP is supplied in Tape & Reel format. Selection depends on assembly process requirements and tape handling capabilities.

Reverse Leakage Characteristics: BAS70-05 RFG and BAS70-05-7-F specify 100 nA @ 50 V reverse leakage, while BAS70-05-HF and BAS70-05-TP specify 200 nA @ 50 V. Both values remain within acceptable limits for small signal Schottky diode applications and do not restrict substitution.

All parts carry EAR99 ECCN classification and HTSUS code 8541.10.0070, confirming regulatory equivalence.

Frequently Asked Questions (FAQ)

Q: Can BAS70-05-TP be used as a direct replacement for BAS70-05-HF in production?

A: Yes. BAS70-05-TP is a parametric equivalent with identical electrical specifications (70 V reverse voltage, 70 mA average rectified current, 1 V forward voltage @ 15 mA, 5 ns reverse recovery time) and mechanical compatibility (SOT-23-3 package, surface mount). Both are ROHS3 compliant with MSL 1 rating. The primary difference is packaging format (Tape & Reel) and manufacturer, which do not affect functional performance.

Q: What is the significance of the reverse leakage current difference between BAS70-05-HF (200 nA) and BAS70-05 RFG (100 nA)?

A: The reverse leakage current specification indicates the small amount of current flowing through the diode in reverse bias condition. BAS70-05-HF specifies 200 nA @ 50 V, while BAS70-05 RFG and BAS70-05-7-F specify 100 nA @ 50 V. Both values are within normal operating parameters for small signal Schottky diodes and do not restrict substitution. Selection may be based on application sensitivity to leakage current, but both parts are functionally equivalent.

Q: Are there packaging differences between the substitute parts?

A: Yes. BAS70-05-HF, BAS70-05 RFG, and BAS70-05-TP are supplied in Tape & Reel (TR) format. BAS70-05-7-F is available in Cut Tape (CT) and Digi-Reel format. All parts use the same SOT-23-3 package footprint. Selection depends on assembly equipment compatibility and tape handling requirements. Tape & Reel format is standard for high-volume automated assembly, while Cut Tape is suitable for lower-volume or manual assembly processes.

Q: Do all substitute parts meet the same compliance standards as BAS70-05-HF?

A: Yes. All substitute parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating. BAS70-05 RFG, BAS70-05-7-F, and BAS70-05-TP all carry REACH Unaffected status. All parts are classified as EAR99 with HTSUS code 8541.10.0070, confirming regulatory and environmental equivalence.

Q: What is the operating temperature range for these diodes?

A: All parts, including BAS70-05-HF and its substitutes, operate across a junction temperature range of -55°C to 125°C. This range is suitable for industrial and commercial applications and is consistent across all listed alternatives.

Q: Can BAS70-05-7-F be used in applications requiring Tape & Reel packaging?

A: BAS70-05-7-F is supplied in Cut Tape and Digi-Reel format, not standard Tape & Reel. If Tape & Reel packaging is required for automated assembly, select BAS70-05-HF, BAS70-05 RFG, or BAS70-05-TP instead. All three maintain identical electrical performance and are available in Tape & Reel format.
