Product details
Overview
SS36FSH from Taiwan Semiconductor is a 3A, 60V Schottky barrier surface-mount rectifier in SOD-128 package, qualified to AEC-Q101, with forward voltage of 0.62V at 3.0A/25°C and reverse leakage of 200µA at 60V/25°C. It delivers high surge current capability (70A IFSM), operates up to 150°C junction temperature, and is used in automotive-grade DC/DC converters and SMPS secondary-side rectification.
For engineers reviewing the SS36FSH datasheet, SS36FSH pinout, SS36FSH application, or SS36FSH equivalent, key selection factors include its 60V VRRM rating, low VF at high temperature, AEC-Q101 qualification, moisture sensitivity level 1 compliance, and SOD-128 thermal performance (RθJL = 16°C/W).
Technical Context
The SS36FSH is a single-die Schottky rectifier optimized for high-efficiency, medium-voltage switching applications. Its 60V repetitive peak reverse voltage and 70A surge rating support robust operation in transient-heavy environments such as automotive power supplies and industrial adapters.
Thermal design is enabled by its SOD-128 package with 16°C/W junction-to-lead resistance and 71°C/W junction-to-ambient rating on a 5mm × 5mm Cu pad. The device exhibits a forward voltage drop of 0.55V at 3.0A and 125°C - critical for maintaining efficiency under elevated ambient conditions.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-3EYH06-M3/45 | Same 60V VRRM, 3A IF, SOD-128 package; VF = 0.65V @ 3A/25°C (slightly higher); no AEC-Q101 claim | Not qualified for automotive; suitable for industrial/commercial SMPS where qualification is not mandated | Select when AEC-Q101 is unnecessary and Vishay supply chain alignment is preferred |
| ON Semiconductor SB360 | 60V VRRM, 3A IF, DO-214AA package; VF = 0.72V @ 3A/25°C; RθJA = 50°C/W (higher thermal resistance) | Larger footprint, lower thermal performance; requires larger copper area for same power dissipation | Select only if SOD-128 is unavailable and board redesign for DO-214AA is acceptable |
Compared with VS-3EYH06-M3/45 and SB360, the SS36FSH offers AEC-Q101 validation and superior thermal resistance (16°C/W vs. ~40–50°C/W), making it optimal for space-constrained, high-reliability automotive and industrial DC/DC converters where long-term parametric stability is required.

FAQ
What is the peak repetitive reverse voltage rating of the SS36FSH?
The SS36FSH has a peak repetitive reverse voltage (VRRM) rating of 60 V. This value is confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version B2103, Page 2). It defines the maximum reverse-biased voltage the device can block continuously without breakdown. Exceeding this voltage risks irreversible avalanche failure. The SS36FSH is part of a series where '36' explicitly denotes the 60V rating - SS34FSH is 40V, SS36FSH is 60V, SS310FSH is 100V, etc.
Is the SS36FSH suitable for automotive applications?
Yes, the SS36FSH is AEC-Q101 qualified, as stated in the FEATURES section of the Taiwan Semiconductor datasheet. This qualification confirms that the SS36FSH has passed stress tests for temperature cycling, humidity bias, mechanical shock, and other reliability criteria defined for discrete semiconductors in automotive power systems. It is intended for use in engine control units, body electronics, and ADAS power supplies where extended temperature operation (−55°C to +150°C) and long-term parametric stability are required. The SS36FSH meets JESD201 Class 2 whisker resistance and J-STD-020 Level 1 moisture sensitivity.
What is the forward voltage drop of the SS36FSH at 3A and 125°C?
The forward voltage drop (VF) of the SS36FSH is 0.55 V maximum at 3.0 A and 125°C, per the Electrical Specifications table (Page 2, "SS36FSH" row, "IF = 3.0A, TJ = 125°C" condition). This value is critical for thermal design because it reflects real-world conduction loss under elevated junction temperature - significantly lower than silicon diodes and competitive with other Schottky rectifiers in the same voltage class. At 25°C, VF is 0.62 V max under the same current, showing beneficial negative temperature coefficient behavior.
What package does the SS36FSH use, and what are its key mechanical attributes?
The SS36FSH uses the SOD-128 surface-mount package, as specified in the MECHANICAL DATA and ORDERING INFORMATION sections. Key attributes include matte tin-plated leads compliant with J-STD-002 solderability, polarity indicated by a cathode band, UL 94V-0 flammability-rated molding compound, and a mass of approximately 0.028 g. The SOD-128 footprint supports automated placement and provides superior thermal performance (RθJL = 16°C/W) compared to legacy packages like DO-214AA, especially when mounted on a 5 mm × 5 mm copper pad per JEDEC test standards.
How does the SS36FSH compare to the SS34FSH in terms of reverse leakage current?
The SS36FSH and SS34FSH share identical reverse leakage (IR) specifications: ≤200 µA at rated VR and 25°C, and ≤80 mA at 125°C (per datasheet Page 2, "Reverse current @ rated VR" table). This equivalence occurs because both devices use the same die process and junction design optimized for low VF in the 40–60V range. However, the SS34FSH's lower 40V VRRM results in slightly lower electric field stress at the same applied voltage, though the datasheet specifies identical IR limits for both parts under their respective rated voltages.
