SRS10100 Equivalent & Substitute Parts

Part Overview

The SRS10100 is a Schottky diode array manufactured by Taiwan Semiconductor Corporation, configured as 1 pair common cathode with a maximum reverse voltage of 100 V and average rectified current of 10 A per diode. The device is housed in a TO-263-3 D2PAK surface mount package and is classified as Active product status with ROHS3 compliance. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design requirements permit operation within the electrical and mechanical parameters of equivalent devices.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SRS10100 is determined by strict equivalence in the following parameters: diode configuration (1 pair common cathode), technology (Schottky), maximum reverse voltage (100 V), package type (TO-263-3 D2PAK), mounting type (surface mount), and regulatory compliance (ROHS3). The substitute part STPS10H100CG-TR meets these core requirements. However, the average rectified current per diode differs between the main part (10 A) and the substitute (5 A). This difference establishes a one-directional substitution relationship: the STPS10H100CG-TR can replace the SRS10100 in applications where the circuit design operates at or below 5 A per diode. The SRS10100 cannot replace the STPS10H100CG-TR in applications requiring 10 A operation.

Parameter Comparison

Engineering Selection Recommendations

The STPS10H100CG-TR is a valid substitute for the SRS10100 when circuit operation does not exceed 5 A per diode. Both parts maintain identical reverse voltage ratings (100 V), package configuration (TO-263-3 D2PAK), and regulatory compliance (ROHS3 and REACH Unaffected). The STPS10H100CG-TR offers operational advantages including lower forward voltage drop (730 mV versus 900 mV at 5 A) and significantly lower reverse leakage current (3.5 µA versus 100 µA at 100 V), along with a higher maximum junction temperature rating (175°C versus 150°C). Selection of the substitute part is appropriate for applications where the 5 A current rating satisfies design requirements. Applications requiring sustained operation above 5 A per diode must use the SRS10100 or identify alternative parts with higher current ratings.

Frequently Asked Questions (FAQ)

Q: Can the STPS10H100CG-TR replace the SRS10100 in all applications?

A: The STPS10H100CG-TR can replace the SRS10100 only in applications where the average rectified current per diode does not exceed 5 A. The SRS10100 is rated for 10 A per diode, while the STPS10H100CG-TR is rated for 5 A per diode. Circuit designs operating above 5 A require the SRS10100 or an alternative part with equivalent or higher current rating.

Q: Are the packages physically identical?

A: Yes. Both the SRS10100 and STPS10H100CG-TR use the TO-263-3 D2PAK package with 2 leads plus tab. The physical footprint and pin configuration are identical, permitting direct PCB layout compatibility.

Q: What are the differences in electrical performance?

A: The STPS10H100CG-TR exhibits lower forward voltage drop (730 mV versus 900 mV at 5 A) and significantly lower reverse leakage current (3.5 µA versus 100 µA at 100 V). Both parts maintain identical reverse voltage ratings (100 V) and fast recovery speed characteristics. The STPS10H100CG-TR also supports a higher maximum junction temperature (175°C versus 150°C).

Q: Are both parts RoHS compliant?

A: Yes. Both the SRS10100 and STPS10H100CG-TR are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components.

Q: What is the diode configuration for both parts?

A: Both parts are configured as 1 pair common cathode Schottky diode arrays in a single package. This configuration provides two independent diodes sharing a common cathode connection.

Q: Can the SRS10100 replace the STPS10H100CG-TR?

A: The SRS10100 can replace the STPS10H100CG-TR in applications where the higher current rating (10 A versus 5 A) and higher forward voltage (900 mV versus 730 mV) are acceptable. However, the higher forward voltage may increase power dissipation in the application.
