SS36LHMHG Equivalent & Substitute Parts

Part Overview

The SS36LHMHG is a Schottky rectifier diode rated for 60 V DC reverse voltage and 3 A average rectified current in a Sub SMA surface mount package. Manufactured by Taiwan Semiconductor Corporation, this component is qualified to AEC-Q101 automotive standards and maintains active product status. Alternative equivalent and substitute parts may be required due to inventory availability, packaging preferences, or application-specific current rating requirements.

Substitute Part Grouping Explanation

Substitution of the SS36LHMHG is determined by the following critical parameters: reverse voltage rating (60 V), package type (DO-219AB Sub SMA), mounting method (surface mount), technology (Schottky), and compliance certifications (ROHS3, REACH Unaffected, EAR99).

Parametric Equivalent: The SS36L RVG maintains identical electrical specifications and package configuration, differing only in packaging format (Tape & Reel versus unspecified packaging for the main part).

Similar Parts with Current Rating Variance: The SS1FH6-M3/H, SS1FH6HM3/H, and SS2FH6HM3/H are similar Schottky rectifiers sharing the same 60 V reverse voltage rating and DO-219AB package. These parts differ in average rectified current ratings (1 A and 2 A respectively) and forward voltage characteristics, making them suitable only for applications where the lower current rating is acceptable.

Engineering Selection Recommendations

Direct Equivalent Substitution: The SS36L RVG is a parametric equivalent to the SS36LHMHG, maintaining identical electrical performance and package specifications. Both parts are manufactured by Taiwan Semiconductor Corporation, carry ROHS3 compliance, and operate within the same temperature range. Selection between these parts is determined by packaging format availability and inventory requirements.

Current-Rated Alternatives: The SS1FH6-M3/H, SS1FH6HM3/H, and SS2FH6HM3/H are suitable substitutes only in applications where the circuit design accommodates reduced average rectified current ratings of 1 A or 2 A respectively. These Vishay parts offer extended operating temperature ranges (-55°C to 175°C) and lower reverse leakage current (3 µA versus 500 µA), with automotive-grade qualification available for SS1FH6HM3/H and SS2FH6HM3/H. Forward voltage characteristics differ across current ratings and must be evaluated against circuit requirements.

Compliance Considerations: All listed parts maintain ROHS3 compliance and REACH Unaffected status. The SS36LHMHG and SS36L RVG carry explicit automotive grade designation with AEC-Q101 qualification. The Vishay SS1FH6HM3/H and SS2FH6HM3/H also carry automotive grade and AEC-Q101 qualification, while SS1FH6-M3/H does not specify automotive grade.

Frequently Asked Questions (FAQ)

Q: Can the SS36L RVG directly replace the SS36LHMHG?

A: Yes. The SS36L RVG is a parametric equivalent with identical voltage rating (60 V), current rating (3 A), forward voltage (750 mV @ 3 A), package type (DO-219AB), and operating temperature range (-55°C to 150°C). The difference is packaging format (Tape & Reel for SS36L RVG).

Q: Are the Vishay SS1FH6 and SS2FH6 series direct replacements?

A: No. These parts have reduced average rectified current ratings (1 A and 2 A respectively) compared to the 3 A rating of the SS36LHMHG. They are suitable only for applications designed for lower current levels. The SS1FH6HM3/H and SS2FH6HM3/H offer automotive qualification matching the main part.

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

A: The SS36LHMHG specifies 500 µA reverse leakage at 60 V, while the Vishay alternatives specify 3 µA. This difference affects power dissipation and leakage behavior in high-impedance circuits. Selection depends on application requirements.

Q: Do all substitute parts share the same package footprint?

A: Yes. All listed parts use the DO-219AB package with Sub SMA supplier designation, ensuring mechanical and electrical compatibility on PCB layouts designed for the SS36LHMHG.

Q: Which substitute parts carry automotive qualification?

A: The SS36L RVG does not specify automotive grade or AEC-Q101 qualification in the provided data. The SS1FH6HM3/H and SS2FH6HM3/H carry both automotive grade and AEC-Q101 qualification. The SS1FH6-M3/H does not specify automotive qualification.

Q: What is the impact of the extended temperature range in Vishay parts?

A: The Vishay SS1FH6 and SS2FH6 series operate to 175°C junction temperature, compared to 150°C for the SS36LHMHG. This extended range provides additional thermal margin in high-temperature applications, provided the current rating is acceptable.
