Engineering Selection Recommendations

Direct Substitution (Parametric Equivalent):

SS13L RVG is a parametric equivalent to SS13LHRQG with identical electrical specifications (30V, 1A, 500mV forward voltage, 400µA reverse leakage). Both parts are Active status and manufactured by Taiwan Semiconductor Corporation. The primary difference is packaging format (Cut Tape vs. standard packaging). This part is suitable for direct substitution in applications requiring identical electrical performance.

Automotive-Grade Substitution:

SS1FL3HM3/H is an automotive-qualified alternative (AEC-Q101) manufactured by Vishay General Semiconductor - Diodes Division. This part matches the 30V reverse voltage and 1A current rating of the SS13LHRQG. The forward voltage is 480mV at 1A (20mV lower than the main part), and reverse leakage is 200µA at 30V (200µA lower than the main part). Operating temperature range extends to 150°C maximum junction temperature. This part is suitable for automotive applications requiring AEC-Q101 qualification.

Higher Current Capacity Substitution:

SS2FL3HM3/H and SS2FL3-M3/H are automotive-qualified alternatives with 2A current rating. These parts maintain 30V reverse voltage and DO-219AB packaging. Forward voltage is 540mV at 2A, and reverse leakage is 200µA at 30V. These parts are suitable for applications requiring higher current capacity while maintaining the same voltage rating and package footprint.

General-Purpose Substitution:

SL03-GS18 (Vishay eSMP® series) provides 1.1A current rating with improved forward voltage characteristics (430mV at 1.1A) and lower reverse leakage (130µA at 30V). This part is suitable for applications where improved efficiency and lower leakage are beneficial, provided the application does not require automotive qualification.

Frequently Asked Questions (FAQ)

Q: Can SS13L RVG be used as a direct replacement for SS13LHRQG?

A: Yes. SS13L RVG is a parametric equivalent with identical electrical specifications: 30V reverse voltage, 1A average rectified current, 500mV forward voltage at 1A, and 400µA reverse leakage at 30V. Both parts use DO-219AB packaging and are Active status. The primary difference is packaging format (Cut Tape). Direct substitution is supported without circuit modification.

Q: What is the difference between SS1FL3HM3/H and SS13LHRQG?

A: Both parts share 30V reverse voltage, 1A current rating, and DO-219AB packaging. SS1FL3HM3/H has lower forward voltage (480mV vs. 500mV at 1A) and lower reverse leakage (200µA vs. 400µA at 30V). SS1FL3HM3/H extends operating temperature to 150°C maximum junction temperature and includes automotive qualification (AEC-Q101). These characteristics make SS1FL3HM3/H suitable for automotive applications with improved thermal performance.

Q: Can SS2FL3HM3/H replace SS13LHRQG in a 1A application?

A: Yes, with design consideration. SS2FL3HM3/H is rated for 2A average rectified current, which exceeds the 1A requirement of SS13LHRQG. Both parts share 30V reverse voltage and DO-219AB packaging. The higher current rating does not create incompatibility in a 1A application. Forward voltage is 540mV at 2A (higher than the 500mV at 1A specification of SS13LHRQG). Reverse leakage is 200µA at 30V (lower than SS13LHRQG). This part is suitable for applications where higher current capacity provides design margin.

Q: Is SL03-GS18 suitable for automotive applications?

A: SL03-GS18 is not listed with automotive qualification or AEC-Q101 certification. For automotive applications requiring AEC-Q101 qualification, use SS1FL3HM3/H or SS2FL3HM3/H instead. SL03-GS18 is suitable for general-purpose applications where automotive qualification is not required.

Q: What is the operating temperature range difference between SS13LHRQG and SS1FL3HM3/H?

A: SS13LHRQG operates from -55°C to 125°C junction temperature. SS1FL3HM3/H operates from -55°C to 150°C junction temperature. The extended upper temperature limit of SS1FL3HM3/H provides additional thermal margin in high-temperature applications.

Q: Can I use SL03-GS18 in place of SS13LHRQG for improved efficiency?

A: SL03-GS18 offers lower forward voltage (430mV at 1.1A vs. 500mV at 1A) and lower reverse leakage (130µA vs. 400µA at 30V), which result in improved efficiency characteristics. Both parts share 30V reverse voltage and DO-219AB packaging. SL03-GS18 is suitable for applications where efficiency improvement is beneficial and automotive qualification is not required.

Q: What packaging formats are available for these substitute parts?

A: SS13LHRQG and SS13L RVG are available in Sub SMA packaging. SS1FL3-M3/H is available in Cut Tape (CT) & Digi-Reel® format. SS1FL3HM3/H, SS2FL3-M3/H, SS2FL3HM3/H, and SL03-GS18 are available in Tape & Reel (TR) format. Packaging format selection depends on procurement and assembly requirements.
