Product details
Overview
SS36ALH from Taiwan Semiconductor is a 3A, 60V Schottky barrier surface-mount rectifier in Thin SMA 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 capability (70A IFSM), low thermal resistance (RθJL = 19°C/W), and is used in automotive-grade DC/DC converters and industrial SMPS.
For engineers reviewing the SS36ALH datasheet, SS36ALH pinout, SS36ALH application, or SS36ALH equivalent, key selection criteria include its 60V VRRM, AEC-Q101 qualification, junction-to-lead thermal performance, moisture sensitivity level 1 rating, and compatibility with automated SMT placement on standard PCB pads.
Technical Context
The SS36ALH is a single-die Schottky rectifier optimized for high-frequency switching applications where low forward voltage drop and fast recovery are critical. Its 60V peak reverse voltage and 3A average forward current rating target mid-voltage power conversion stages.
Thermal design is supported by verified RθJL = 19°C/W and RθJA = 81°C/W (measured on 5mm × 5mm Cu pad), while its 125°C-rated forward voltage (0.55V at 3.0A) ensures stable conduction under elevated ambient conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - Maximum repetitive reverse blocking voltage; defines safe operating range in DC/DC flyback or buck output rectification |
| IF | 3 A - Continuous average forward current; supports compact 12–24V input converters up to ~36W output |
| IFSM | 70 A - Non-repetitive surge current (8.3ms); withstands inrush and transient overloads without failure |
| VF | 0.62 V max @ 3.0A, 25°C - Low conduction loss improves efficiency and reduces heatsink requirements |
| IR | 200 µA max @ 60V, 25°C - Low leakage preserves standby power in always-on systems |
| TJ max | 150 °C - Enables operation in under-hood automotive or enclosed industrial environments |
| RθJL | 19 °C/W - Efficient heat transfer to PCB lead; enables thermal management via copper pour without external heatsink |
Pinout & Package

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, but TO-277 package (higher RθJA = 100°C/W) | Larger footprint; less suitable for ultra-thin designs | Prefer SS36ALH when PCB thickness or thermal resistance to ambient is constrained |
| ON Semiconductor SB360-E3/54 | 60V VRRM, 3A IF, SMA package, but not AEC-Q101 qualified and higher VF (0.72V typ @ 3A) | Not rated for automotive use; higher conduction loss | Choose SS36ALH for AEC-Q101 compliance and lower power loss in thermally sensitive layouts |
Compared with VS-3EYH06-M3/45 and SB360-E3/54, the SS36ALH offers superior thermal performance in a thinner profile and certified automotive reliability-making it optimal for space- and qualification-critical power stages where efficiency and long-term stability are prioritized.

FAQ
What is the maximum junction temperature rating for the SS36ALH?
The SS36ALH has a maximum junction temperature (TJ) rating of +150°C, enabling reliable operation in under-hood automotive environments and enclosed industrial enclosures. This rating is validated per the device's absolute maximum ratings table and confirmed in thermal derating curves. The SS36ALH maintains specified electrical performance-including forward voltage and leakage current-up to this limit when proper PCB thermal design is implemented.
Is the SS36ALH suitable for automotive applications?
Yes, the SS36ALH is AEC-Q101 qualified, meaning it has passed stress tests for temperature cycling, humidity, mechanical shock, and high-temperature reverse bias required for automotive power electronics. Its Thin SMA package, matte tin plating, and moisture sensitivity level 1 make it compatible with automotive manufacturing processes. The SS36ALH is explicitly recommended for on-board DC/DC converters and lighting systems in vehicles.
What is the forward voltage of the SS36ALH at 3.0A and 125°C?
The SS36ALH exhibits a typical forward voltage of 0.55V and a maximum of 0.63V at 3.0A and 125°C, per the Electrical Specifications table. This low, temperature-stable VF reduces conduction losses in high-ambient applications and contributes to improved system efficiency compared to higher-VF alternatives. The SS36ALH's VF behavior is documented across temperature and current in Figures 8 and 10 of the datasheet.
Does the SS36ALH have a defined polarity marking?
Yes, the SS36ALH uses a cathode band to indicate polarity-consistent with industry-standard diode marking. The band is printed on the cathode end of the Thin SMA package and aligns with the cathode terminal in the pinout. This marking is critical for correct orientation during automated placement and manual inspection. The SS36ALH's polarity is also reinforced by its mechanical outline drawing and suggested pad layout documentation.
What packaging and reel quantity is available for the SS36ALH?
The SS36ALH is supplied in Tape & Reel format with 14,000 units per reel, as specified in the Ordering Information section. This packaging supports high-speed pick-and-place assembly and is compatible with standard SMT equipment. The Thin SMA package dimensions and tape specifications comply with EIA-481 standards, ensuring reliable feeding and placement. Aetrix Electronics stocks SS36ALH in full reels and offers cut-tape options for prototyping and low-volume builds.
