SB01-05Q-TL-E Equivalent & Substitute Parts

Part Overview

The SB01-05Q-TL-E is an active Schottky diode manufactured by onsemi, rated for 50V DC reverse voltage and 100mA average rectified current. This component is designed for surface mount applications in small signal rectification circuits where fast switching and low forward voltage drop are required. The part is supplied in Tape & Reel packaging with SC-70/SOT-323 package configuration.

Equivalent and substitute parts are identified to support design flexibility, supply chain continuity, and component availability across manufacturing cycles. Substitutes must maintain functional compatibility within the specified electrical and mechanical parameters of the application circuit.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SB01-05Q-TL-E is determined by the following critical parameters:

Electrical Compatibility Criteria:

• Schottky diode technology classification
• Reverse voltage rating equal to or greater than 50V
• Average rectified current rating equal to or greater than 100mA
• Forward voltage drop within acceptable circuit operating margins
• Reverse recovery time suitable for small signal applications
• Reverse leakage current within acceptable limits for the application

Mechanical Compatibility Criteria:

• Surface mount mounting type
• SC-70 or SOT-323 package configuration
• Tape & Reel supply format

Compliance Criteria:

• ROHS3 compliance status
• MSL rating of 1 (Unlimited)
• REACH unaffected status
• Active product status

The identified substitute part meets these criteria with the exception of reverse voltage rating, which is specified at a lower maximum value. This substitution is valid only in applications where the circuit reverse voltage does not exceed the substitute part's rated maximum.

Engineering Selection Recommendations

Primary Part Selection (SB01-05Q-TL-E): The SB01-05Q-TL-E is the preferred component for applications requiring 50V reverse voltage rating. This part is active, ROHS3 compliant, and carries MSL rating 1 with unlimited moisture sensitivity protection. The part is available in high inventory volume (8850 pcs) and maintains full compliance with REACH and EAR99 export classifications.

Substitute Part Selection (1SS322(TE85L,F)): The 1SS322(TE85L,F) from Toshiba Semiconductor and Storage is a valid substitute for applications where the maximum reverse voltage does not exceed 40V. This part is also active and ROHS3 compliant with MSL rating 1. The substitute exhibits lower reverse leakage current (5 µA @ 40V versus 15 µA @ 25V) and is available with inventory of 4300 pcs.

Selection Constraints:

• The substitute part has a maximum reverse voltage rating of 40V, which is 10V lower than the primary part. Substitution is valid only when circuit design confirms reverse voltage stress does not exceed 40V.
• The substitute part exhibits higher forward voltage drop (600 mV @ 100 mA versus 550 mV @ 100 mA), resulting in approximately 50 mV additional voltage drop. This difference must be evaluated in power dissipation and circuit margin calculations.
• Both parts maintain identical current ratings, package configurations, and compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can the 1SS322(TE85L,F) be used as a direct replacement for the SB01-05Q-TL-E in all applications?

A: No. The 1SS322(TE85L,F) has a maximum reverse voltage rating of 40V compared to the SB01-05Q-TL-E rating of 50V. Substitution is valid only in applications where the circuit reverse voltage does not exceed 40V. Circuit analysis must confirm this condition before substitution.

Q: What is the impact of the forward voltage difference between these parts?

A: The 1SS322(TE85L,F) has a maximum forward voltage of 600 mV @ 100 mA, compared to 550 mV @ 100 mA for the SB01-05Q-TL-E. This 50 mV difference results in approximately 5 mW additional power dissipation at 100 mA. Applications with tight power budgets or thermal constraints must account for this difference.

Q: Are both parts available in the same package configuration?

A: Yes. Both the SB01-05Q-TL-E and 1SS322(TE85L,F) are supplied in SC-70/SOT-323 surface mount packages with Tape & Reel packaging. No PCB layout or assembly process modifications are required for substitution.

Q: Do both parts meet the same compliance and environmental standards?

A: Yes. Both parts are ROHS3 compliant, carry MSL rating 1 (Unlimited), are REACH unaffected, and maintain EAR99 export classification. Both parts are classified as active products with full manufacturing support.

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

A: The 1SS322(TE85L,F) exhibits 5 µA @ 40V reverse leakage, while the SB01-05Q-TL-E exhibits 15 µA @ 25V. The substitute part demonstrates lower leakage current at its rated voltage. Direct comparison at identical voltage conditions is not provided in the specifications.

Q: Are there any temperature operating range differences?

A: The SB01-05Q-TL-E specifies a junction temperature range of -55°C to 125°C. The 1SS322(TE85L,F) specifies a maximum junction temperature of 125°C without a stated minimum. Applications requiring operation below 0°C should confirm the substitute part's low-temperature performance capability.
