Substitute Part Grouping Explanation

Substitute parts for the SS13LHMHG are grouped based on the following substitution criteria:

Parametric Equivalents maintain identical electrical specifications across voltage rating, current rating, forward voltage, and reverse leakage characteristics. These parts are direct replacements with no circuit performance impact.

Similar Parts share the same reverse voltage rating (30 V) and package form factor (DO-219AB) but may differ in one or more of the following parameters:

Average rectified current (Io): 1 A to 2 A or 1.1 A
Forward voltage (Vf): 430 mV to 540 mV at rated current
Reverse leakage current: 130 µA to 400 µA at 30 V
Operating temperature range: -55°C to 125°C or -55°C to 150°C
Reverse recovery time (trr): specified or unspecified

Parts with higher current ratings (1.1 A or 2 A) are suitable for applications requiring additional current margin. Parts with lower forward voltage or reverse leakage offer improved efficiency or lower standby power consumption. All substitute parts maintain Schottky technology, fast recovery speed characteristics, and surface mount configuration.

Engineering Selection Recommendations

Direct Replacement (Parametric Equivalent): SS13L RVG is a parametric equivalent to SS13LHMHG with identical electrical specifications. The primary difference is packaging format (Cut Tape versus standard packaging). This part is suitable for direct substitution where packaging compatibility with assembly equipment is confirmed.

Automotive-Grade Substitutes: SS1FL3HM3/H and SS2FL3HM3/H both carry AEC-Q101 automotive qualification matching the original part's grade. SS1FL3HM3/H maintains the 1 A current rating with improved forward voltage (480 mV versus 500 mV) and lower reverse leakage (200 µA versus 400 µA), offering enhanced efficiency. SS2FL3HM3/H provides 2 A current capacity for applications requiring higher current margin, with automotive qualification maintained.

General-Purpose Substitutes: SS1FL3-M3/H and SS2FL3-M3/H are non-automotive variants offering equivalent or superior electrical performance. SS1FL3-M3/H matches the 1 A rating with improved forward voltage and leakage characteristics. Both parts extend the operating temperature range to 150°C maximum junction temperature.

Higher Current Alternative: SL03-GS18 from Vishay provides 1.1 A current rating with superior forward voltage (430 mV) and reverse leakage (130 µA) characteristics. This part is suitable for applications where additional current capacity and lower power dissipation are beneficial.

Frequently Asked Questions (FAQ)

Q: Can SS13L RVG replace SS13LHMHG directly in production? A: Yes. SS13L RVG is a parametric equivalent with identical electrical specifications. Verify that the Cut Tape packaging format is compatible with your assembly process and equipment.

Q: What is the difference between SS1FL3HM3/H and SS1FL3-M3/H? A: Both parts maintain 1 A current rating and 30 V reverse voltage. SS1FL3HM3/H carries AEC-Q101 automotive qualification and is packaged in Tape & Reel format. SS1FL3-M3/H is a general-purpose variant without automotive qualification, available in Cut Tape and Digi-Reel packaging. Electrical performance is identical between the two.

Q: Can I use SS2FL3HM3/H (2 A) in place of SS13LHMHG (1 A)? A: Yes. SS2FL3HM3/H is rated for 2 A average rectified current, providing higher current capacity than the 1 A requirement of SS13LHMHG. The 30 V reverse voltage rating and DO-219AB package are identical. Forward voltage at 2 A operation is 540 mV. This part is suitable for applications where additional current margin is required.

Q: What are the key differences between SL03-GS18 and SS13LHMHG? A: SL03-GS18 is manufactured by Vishay and rated for 1.1 A (versus 1 A), with superior forward voltage of 430 mV and lower reverse leakage of 130 µA. Both parts share the 30 V reverse voltage rating and DO-219AB package. SL03-GS18 does not carry automotive qualification.

Q: Which substitute part offers the lowest power dissipation? A: SL03-GS18 offers the lowest forward voltage at 430 mV @ 1.1 A, resulting in the lowest power dissipation in forward conduction. SS1FL3-M3/H and SS1FL3HM3/H both provide 480 mV @ 1 A, also lower than the original 500 mV specification.

Q: Are all substitute parts RoHS3 compliant? A: Yes. All listed substitute parts maintain ROHS3 compliance and REACH Unaffected status, matching the environmental compliance profile of SS13LHMHG.

Q: What is the operating temperature range difference between SS13LHMHG and Vishay substitutes? A: SS13LHMHG operates from -55°C to 125°C junction temperature. Vishay substitute parts (SS1FL3 and SS2FL3 series) extend the maximum junction temperature to 150°C, providing additional thermal margin in high-temperature applications.

Q: Can I use a 2 A rated diode in a 1 A application? A: Yes. A higher current-rated diode (SS2FL3 series at 2 A) is suitable for applications designed for 1 A operation. The diode will operate within its safe operating area with additional current margin. Verify that forward voltage and reverse leakage specifications are acceptable for your circuit design.
