Primary Substitution Criteria:

Voltage - DC Reverse (Vr) Maximum: 150V (exact match required)
Technology: Schottky (exact match required)
Package / Case: DO-214AA, SMB (exact match required)
Mounting Type: Surface Mount (exact match required)

Engineering Selection Recommendations

Parametric Equivalents (Direct Replacements):

The SS215 (Tape & Reel packaging) and SS215H (Automotive grade, AEC-Q101 qualified) are parametric equivalents to the discontinued SS215 R5G. Both parts maintain identical electrical specifications: 150V reverse voltage, 2A average rectified current, 950mV forward voltage at 2A, and 100µA reverse leakage current at 150V. The SS215H includes automotive qualification and is suitable for applications requiring AEC-Q101 compliance. Both parts are in active production status.

Current-Rated Substitutes:

For applications where higher current capacity is acceptable, CDBB3150-HF, CDBB5150-HF, SBR3150SB-13, STPS3150U, and STPS3150UY provide 3A or 5A ratings while maintaining the 150V reverse voltage specification and DO-214AA package. These parts are suitable for designs with current margin or where circuit topology permits higher current-rated components.

Forward Voltage Considerations:

CDBB2150-HF and SK2150-LTP are 2A-rated alternatives with forward voltage specifications of 875mV and 900mV respectively, compared to the original 950mV specification. These parts offer improved efficiency characteristics. STPS3150U and STPS3150UY provide the lowest forward voltage at 820mV, with STPS3150UY offering automotive-grade qualification.

Reverse Leakage Characteristics:

The original SS215 R5G specifies 100µA reverse leakage at 150V. Substitute parts from Comchip Technology (CDBB series) and Diodes Incorporated (SBR3150SB-13) specify 500µA reverse leakage. STMicroelectronics parts (STPS3150U and STPS3150UY) specify 2µA reverse leakage, representing superior leakage performance.

Compliance and Certifications:

All listed parts maintain ROHS3 compliance, MSL Level 1 (Unlimited), and REACH Unaffected status. The SS215H and STPS3150UY carry automotive-grade qualification (AEC-Q101), suitable for automotive applications.

Frequently Asked Questions (FAQ)

Q: Can I use a higher current-rated diode as a substitute for the SS215 R5G?

A: Yes. The CDBB3150-HF, CDBB5150-HF, SBR3150SB-13, STPS3150U, and STPS3150UY are rated for 3A or 5A and maintain the 150V reverse voltage specification and DO-214AA package. Higher current ratings do not degrade circuit performance in rectification applications. Verify that the forward voltage drop at the actual operating current is acceptable for your thermal design.

Q: What is the difference between SS215 and SS215H?

A: Both parts are parametric equivalents with identical electrical specifications. The SS215H carries automotive-grade qualification (AEC-Q101) and is suitable for automotive applications. The SS215 is the standard industrial version. Select SS215H for automotive designs requiring AEC-Q101 compliance.

Q: Are there any compatibility issues with the DO-214AA package?

A: No. All substitute parts listed use the DO-214AA (SMB) surface mount package with identical pin configuration and footprint. Direct PCB layout substitution is possible without modification.

Q: How do forward voltage differences affect circuit performance?

A: Forward voltage drop directly impacts power dissipation and thermal performance. The original SS215 R5G specifies 950mV at 2A. Substitutes range from 820mV to 950mV at their respective rated currents. Lower forward voltage reduces power loss and heat generation. Verify that the substitute part's forward voltage at your actual operating current is acceptable for thermal budget and efficiency requirements.

Q: What is the significance of reverse leakage current differences?

A: Reverse leakage current affects standby power consumption and circuit performance in high-impedance applications. The original SS215 R5G specifies 100µA at 150V. Comchip parts specify 500µA, while STMicroelectronics parts specify 2µA. For most rectification applications, these differences are negligible. For precision analog circuits or low-power standby conditions, select STPS3150U or STPS3150UY for superior leakage performance.

Q: Is the SS215 R5G still available from any supplier?

A: The SS215 R5G is discontinued at DiGi Electronics. The active equivalent SS215 (Tape & Reel packaging) is available as a direct replacement with identical specifications and is currently in stock.

Q: Can I use STPS3150UY in non-automotive applications?

A: Yes. STPS3150UY is automotive-qualified but suitable for any application. The automotive qualification indicates additional testing and reliability assurance, making it a premium choice for any application requiring high reliability.

Q: What packaging options are available for substitutes?

A: All substitute parts are supplied in Tape & Reel (TR) or Cut Tape (CT) & Digi-Reel® packaging for surface mount assembly. The DO-214AA (SMB) package is standard across all parts listed.
