SRS10150 Equivalent & Substitute Parts

Part Overview

The SRS10150 is a Schottky diode array manufactured by Taiwan Semiconductor Corporation, configured as 1 pair common cathode with a maximum reverse voltage of 150 V and average rectified current of 10 A per diode. The device is packaged in TO-263-3 (D2PAK) surface mount configuration and is RoHS3 compliant. This part is currently active in production with 804 pieces in stock.

Equivalent and substitute parts are identified to provide design flexibility for applications requiring Schottky diode arrays with matching or compatible electrical and mechanical specifications. Substitutes may differ in current ratings, forward voltage characteristics, or packaging variants while maintaining compatibility with the primary application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SRS10150 are identified based on the following critical parameters that determine functional compatibility:

Primary Compatibility Criteria:

• Diode Configuration: 1 Pair Common Cathode
• Technology: Schottky
• Voltage - DC Reverse (Vr) (Max): 150 V
• Package / Case: TO-263-3, D2PAK (2 Leads + Tab), TO-263AB
• Mounting Type: Surface Mount

Secondary Variation Parameters:

• Current - Average Rectified (Io) (per Diode): May vary from 5 A to 20 A
• Voltage - Forward (Vf) (Max) @ If: May vary within acceptable operating range
• Operating Temperature - Junction: May extend beyond base specification
• Current - Reverse Leakage @ Vr: May vary based on manufacturer process

The identified substitutes maintain identical reverse voltage rating (150 V), diode configuration (1 pair common cathode), technology (Schottky), and package format (TO-263-3 D2PAK). Current ratings differ to accommodate various application requirements, with MBRB10150CT rated at 5 A and STPS40150CG-TR rated at 20 A, compared to the SRS10150 base rating of 10 A.

Parameter Comparison

Engineering Selection Recommendations

MBRB10150CT (Diodes Incorporated): This substitute is suitable for applications where current requirements are limited to 5 A per diode. The MBRB10150CT offers lower forward voltage (890 mV @ 5 A) compared to the SRS10150 (1 V @ 5 A) and reduced reverse leakage current (50 µA @ 150 V). The device carries AEC-Q101 automotive qualification and extended operating temperature range (-55°C ~ 175°C). Packaging is supplied in Tube format rather than Tape & Reel. This part is suitable for cost-sensitive applications or where automotive-grade reliability is required.

STPS40150CG-TR (STMicroelectronics): This substitute is suitable for applications requiring higher current capacity of 20 A per diode. The STPS40150CG-TR provides superior reverse leakage performance (8 µA @ 150 V) and extended maximum junction temperature (175°C). Forward voltage at 20 A is 920 mV. Packaging is supplied in Cut Tape (CT) & Digi-Reel® format. This part is appropriate for high-current applications or where lower leakage characteristics are critical.

All three parts maintain identical reverse voltage rating (150 V), diode configuration (1 pair common cathode), Schottky technology, and TO-263-3 D2PAK package format. All parts are RoHS3 compliant and active in production.

Frequently Asked Questions (FAQ)

Q: Can MBRB10150CT replace SRS10150 in all applications?

A: MBRB10150CT is suitable for applications where the maximum current requirement per diode does not exceed 5 A. The SRS10150 is rated for 10 A per diode. If the application requires the full 10 A capacity, MBRB10150CT is not appropriate. For applications operating at 5 A or below, MBRB10150CT provides compatible electrical and mechanical characteristics.

Q: Can STPS40150CG-TR replace SRS10150 in all applications?

A: STPS40150CG-TR is electrically and mechanically compatible with SRS10150. The 20 A current rating of STPS40150CG-TR exceeds the 10 A requirement of SRS10150, making it suitable for the same applications. The lower reverse leakage current (8 µA vs. 100 µA) and extended temperature range are additional benefits for demanding applications.

Q: Are the packages identical between all three parts?

A: All three parts use the TO-263-3 D2PAK (2 Leads + Tab) surface mount package. However, the packaging format (how the parts are supplied) differs: SRS10150 is supplied in Tape & Reel (TR), MBRB10150CT in Tube, and STPS40150CG-TR in Cut Tape (CT) & Digi-Reel®. The physical component package is identical; only the supply format differs.

Q: What is the significance of the common cathode configuration?

A: The 1 pair common cathode configuration means the diode array contains two diodes sharing a common cathode terminal. This configuration is fixed across all three parts and determines the pinout and circuit connectivity. Substitutes must maintain this configuration for direct compatibility.

Q: Do all parts meet RoHS3 compliance?

A: Yes, all three parts (SRS10150, MBRB10150CT, and STPS40150CG-TR) are RoHS3 compliant and REACH unaffected.

Q: What is the difference in forward voltage between the parts?

A: SRS10150 has a maximum forward voltage of 1 V @ 5 A. MBRB10150CT has 890 mV @ 5 A, and STPS40150CG-TR has 920 mV @ 20 A. Forward voltage varies with current; direct comparison at identical current levels shows MBRB10150CT has lower forward voltage at 5 A operation.

Q: Which part has the lowest reverse leakage current?

A: STPS40150CG-TR has the lowest reverse leakage current at 8 µA @ 150 V, compared to MBRB10150CT at 50 µA @ 150 V and SRS10150 at 100 µA @ 150 V.

Q: Are there temperature rating differences?

A: SRS10150 operates from -55°C to 150°C junction temperature. MBRB10150CT extends to -55°C to 175°C, and STPS40150CG-TR has a maximum junction temperature of 175°C. Both substitutes offer extended high-temperature operation.
