Parametric Equivalents are parts manufactured by Taiwan Semiconductor Corporation with identical electrical specifications (SSL24 and SSL24H). These parts maintain the same voltage, current, and forward voltage characteristics and differ only in product status or packaging configuration.

Similar Parts are manufactured by alternative suppliers (Diodes Incorporated, Microchip Technology, Vishay General Semiconductor) and meet the core electrical requirements but may exhibit variations in forward voltage, reverse leakage current, or operating temperature range. These parts are suitable for substitution when the application tolerates the specified parameter variations.

Frequently Asked Questions (FAQ)

Q: Can SSL24 R5G be directly replaced with SSL24 or SSL24H?

A: Yes. SSL24 and SSL24H are parametric equivalents with identical electrical specifications (40V, 2A, 410mV forward voltage). Both are manufactured by Taiwan Semiconductor Corporation and maintain ROHS3 compliance. SSL24H includes AEC-Q101 automotive qualification. Both parts are currently in active product status.

Q: What is the difference between B240-13-F and B240Q-13-F?

A: Both parts are 40V, 2A Schottky diodes manufactured by Diodes Incorporated with identical electrical specifications. B240-13-F is supplied in Cut Tape (CT) & Digi-Reel packaging, while B240Q-13-F is supplied in Tape & Reel (TR) packaging. B240Q-13-F carries AEC-Q101 automotive qualification. Selection depends on packaging requirements and application grade.

Q: Can I use a 1A rated diode (5819SMJ/TR13 or B140BQ-13-F) as a substitute for SSL24 R5G?

A: No. The SSL24 R5G is rated for 2A average rectified current. Using a 1A rated diode in a 2A application will result in component overstress, reduced reliability, and potential failure. Substitution must maintain or exceed the current rating of the original part.

Q: Can I use a 3A rated diode (B340BQ-13-F or B340LB series) as a substitute for SSL24 R5G?

A: Yes. The 3A rated diodes (B340BQ-13-F, B340LB-E3/52T, B340LB-E3/5BT) are suitable substitutes for 2A applications. These parts provide increased current capacity and maintain the 40V voltage rating and DO-214AA package compatibility. The higher current rating provides design margin and does not negatively impact circuit performance.

Q: What is the significance of forward voltage differences between SSL24 R5G (410mV) and B240 series (500mV)?

A: Forward voltage affects power dissipation and thermal performance. The 90mV difference between SSL24 R5G (410mV @ 2A) and B240-13-F (500mV @ 2A) results in increased power loss in the substitute part. For a 2A circuit, this represents approximately 180mW additional dissipation. Applications with tight thermal budgets or high-frequency operation should account for this difference.

Q: Are all substitute parts RoHS compliant?

A: No. 5819SMJ/TR13 (Microchip Technology) is RoHS non-compliant. All other substitute parts listed (SSL24, SSL24H, B140BQ-13-F, B240-13-F, B240A-13-F, B240Q-13-F, B340BQ-13-F, B340LB-E3/52T, B340LB-E3/5BT) are ROHS3 compliant. RoHS compliance is required for applications subject to environmental regulations or customer specifications.

Q: What is the difference between DO-214AA (SMB) and DO-214AC (SMA) packages?

A: DO-214AA (SMB) and DO-214AC (SMA) are different surface mount package footprints. B240A-13-F uses DO-214AC (SMA) package, while SSL24 R5G and most substitute parts use DO-214AA (SMB) package. These packages are not interchangeable on the same PCB. Selection of B240A-13-F requires PCB layout modification to accommodate SMA package dimensions.

Q: Which substitute parts carry automotive qualification?

A: SSL24H, B140BQ-13-F, B240Q-13-F, and B340BQ-13-F carry AEC-Q101 automotive qualification. B340LB-E3/52T and B340LB-E3/5BT do not explicitly list AEC-Q101 qualification in the provided specifications. Automotive applications should select parts with documented AEC-Q101 qualification.

Q: What is the operating temperature range difference between SSL24 R5G and substitute parts?

A: SSL24 R5G operates from -55°C to 125°C. Most substitute parts (B240 series, B340 series) operate from -65°C to 150°C, providing extended temperature range. 5819SMJ/TR13 operates from -55°C to 150°C. Applications requiring operation below -55°C or above 125°C should select substitute parts with extended temperature specifications.
