BAS7005TC Equivalent & Substitute Parts

Part Overview

The BAS7005TC is a Schottky diode array manufactured by Diodes Incorporated, configured as 1 pair common cathode in a SOT-23-3 surface mount package. This component is rated for 70 V DC reverse voltage with 15 mA average rectified current per diode. The part is classified as obsolete, necessitating identification of active equivalent and substitute components that maintain electrical and mechanical compatibility for ongoing production and repair applications.

Substitute Part Grouping Explanation

Substitution of the BAS7005TC is determined by the following critical parameters:

Electrical Compatibility Requirements:

Diode configuration must be 1 pair common cathode
Technology must be Schottky
Voltage - DC Reverse (Vr) must be 70 V or greater
Current - Average Rectified (Io) must be equal to or greater than 15 mA per diode
Operating temperature range must encompass the application requirements

Mechanical Compatibility Requirements:

Mounting type must be surface mount
Package / Case must be compatible with SOT-23-3 footprint or equivalent surface mount packages (SOT-23-3, TO-236-3, SC-59, or SC-70/SOT-323 with appropriate PCB layout considerations)

Compliance Requirements:

RoHS3 compliance required
Moisture Sensitivity Level 1 (Unlimited) preferred

Substitute parts are grouped into two categories: direct SOT-23-3 package equivalents and alternative package options (SOT-323) that require PCB layout modification but maintain electrical specifications.

Engineering Selection Recommendations

Direct Package Equivalents (SOT-23-3):

The following parts provide direct electrical and mechanical substitution without PCB layout modification:

BAS7005E6327HTSA1 (Infineon Technologies): Active status with 70 mA current rating, 150°C maximum junction temperature, and RoHS3 compliance. Reverse leakage of 100 nA @ 50 V.

Alternative Package Options (SOT-323):

The following parts require PCB layout modification due to different package footprint but maintain electrical specifications:

BAS70-05W,115 (Nexperia USA Inc.): Active status in SC-70/SOT-323 package with 70 mA current rating and 150°C maximum junction temperature.

Frequently Asked Questions (FAQ)

Q: Can BAS70-05-TP directly replace BAS7005TC without PCB modification?

A: Yes. BAS70-05-TP maintains the same SOT-23-3 package footprint, diode configuration (1 pair common cathode), Schottky technology, 70 V reverse voltage rating, and surface mount mounting type. The 70 mA current rating exceeds the original 15 mA specification, providing operational margin.

Q: What is the difference between SOT-23-3 and SOT-323 packages?

A: SOT-23-3 (TO-236-3, SC-59) and SOT-323 (SC-70) are different surface mount package footprints with different pin spacing and dimensions. Direct substitution between these packages requires PCB layout modification. Parts BAS70-05W,115 and BAS70-05W,135 use SOT-323 packaging and cannot be used as drop-in replacements without redesign.

Q: Are all substitute parts RoHS3 compliant?

A: All listed substitute parts except BAS70-05,215 explicitly specify RoHS3 compliance. BAS70-05,215 does not include RoHS status in the provided specifications.

Q: What is the significance of the higher current rating (70 mA vs. 15 mA) in substitute parts?

A: The 70 mA current rating in substitute parts indicates higher current handling capability. This provides design margin and allows the component to operate safely in applications requiring up to 70 mA per diode. The original 15 mA specification is a minimum requirement that all substitutes exceed.

Q: Which substitute part has the lowest reverse leakage current?

A: BAS7005E6327HTSA1 (Infineon Technologies) specifies 100 nA @ 50 V reverse leakage, which is lower than the original BAS7005TC specification of 200 nA @ 50 V. Parts BAS70-05,215, BAS70-05,235, BAS70-05FILM, BAS70-05W,115, and BAS70-05W,135 specify 10 µA @ 70 V, which is higher than the original specification.

Q: What is the operating temperature difference between BAS70-05-TP and other substitutes?

A: BAS70-05-TP specifies a maximum junction temperature of 125°C, while most other substitutes specify 150°C. This represents a 25°C difference in maximum operating temperature. Applications requiring operation above 125°C should use alternatives with 150°C ratings.

Q: Can I use BAS70-05,215 in a new design if RoHS3 compliance is required?

A: BAS70-05,215 does not include RoHS3 compliance specification in the provided data. For applications requiring documented RoHS3 compliance, use alternative parts that explicitly specify ROHS3 Compliant status.

Q: What packaging options are available for direct SOT-23-3 substitutes?

A: Direct SOT-23-3 substitutes are available in the following packaging formats: Cut Tape (CT) & Digi-Reel (BAS7005E6327HTSA1, BAS70-05FILM), Tape & Reel (TR) (BAS70-05,235, BAS70-05-TP), and unspecified packaging (BAS70-05,215).
