Product details

Overview

SS26FSH from Taiwan Semiconductor is a 2 A, 60 V Schottky barrier surface-mount rectifier in SOD-128 package, featuring low forward voltage (0.60 V typ. at 2 A, 25°C), high surge capability (145 A @ 1 ms), AEC-Q101 qualification, and 150°C maximum junction temperature - used in automotive-grade DC/DC converters and industrial SMPS.

For engineers reviewing the SS26FSH datasheet, SS26FSH pinout, SS26FSH application, or SS26FSH equivalent, key selection criteria include forward voltage at elevated temperature, reverse leakage at 125°C, thermal resistance (R_θJL = 18°C/W), junction capacitance (95 pF), and SOD-128 mechanical compatibility with automated placement.

Technical Context

The SS26FSH employs a single-die Schottky structure optimized for low conduction loss in medium-voltage switching applications. Its 60 V V_RRM, 2 A continuous forward current rating, and 145 A peak surge current support high-efficiency operation in compact power stages.

Thermal performance is defined by R_θJL = 18°C/W and R_θJA = 75°C/W on a 5 mm × 5 mm Cu pad PCB. The device meets JESD201 Class 2 whisker resistance and J-STD-020 Level 1 moisture sensitivity requirements.

Cathode	Current exit point during forward conduction; marked by band	Connected to higher-potential node (e.g., output rail); polarity must be verified before reflow to prevent reverse-bias failure.

Key Features

Feature	Design Value
AEC-Q101 qualified	Validated for automotive power electronics including engine control modules and body electronics requiring reliability under thermal cycling and vibration.
Low V_F at 125°C	0.54 V (max) at 2 A, 125°C - Maintains efficiency in high-ambient environments where silicon diodes degrade significantly.
High I_FSM (145 A)	Withstands short-duration inrush currents in LED drivers and AC/DC front-ends without bond-wire fusing.
J-STD-020 Level 1	No floor-life limitation or bake requirement prior to reflow; supports standard SMT assembly without special handling.

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-2EY60-M3/57T	Same 60 V V_RRM, 2 A I_F, but TO-277A package; V_F = 0.62 V (max) at 2 A, 25°C; R_θJA = 90°C/W.	Higher thermal resistance limits power handling in space-constrained PCBs; requires larger copper area for equivalent cooling.	Select when legacy TO-277A footprint is fixed and thermal budget permits 15°C higher junction rise.
ON Semiconductor SB260	SOD-123 package; 60 V V_RRM, 2 A I_F; V_F = 0.72 V (max) at 2 A, 25°C; no AEC-Q101 qualification.	Not automotive-qualified; higher V_F increases conduction loss by ~0.25 W at full load; smaller package reduces thermal mass.	Acceptable for cost-sensitive consumer adapters where AEC-Q101 and thermal performance are non-critical.

Compared with VS-2EY60-M3/57T and SB260, the SS26FSH delivers superior thermal performance (R_θJL = 18°C/W), automotive qualification, and lower forward voltage - making it optimal for high-reliability, thermally constrained 2 A rectification where SOD-128 is acceptable.

FAQ

What is the maximum junction temperature rating for SS26FSH?

The SS26FSH has a maximum junction temperature (T_J) of +150°C, validated across its full operating range. This rating allows reliable operation in under-hood automotive environments and sealed industrial enclosures. Derating curves in the SS26FSH datasheet confirm usable current capacity down to ~1.1 A at 100°C case temperature. Thermal design must respect R_θJL = 18°C/W to avoid exceeding this limit.

Is SS26FSH suitable for automotive applications?

Yes, the SS26FSH is AEC-Q101 qualified and explicitly rated for automotive use. It passes stress tests including temperature cycling, humidity bias, and mechanical shock per AEC-Q101 Rev D. Its 150°C T_J max, halogen-free construction, and JESD201 Class 2 whisker resistance make it appropriate for engine control units, body electronics, and ADAS power supplies where long-term reliability is critical. SS26FSH is not intended for safety-critical airbag or braking systems.

What is the forward voltage of SS26FSH at 2 A and 125°C?

The SS26FSH forward voltage is 0.54 V (maximum) at 2 A and 125°C junction temperature, per the Electrical Specifications table. At typical operating conditions (2 A, 25°C), V_F is 0.60 V (typical) and 0.70 V (maximum). This low, temperature-stable V_F enables consistent efficiency in high-ambient applications such as LED drivers and automotive DC/DC converters where thermal management is limited.

Does SS26FSH have a specified junction-to-case thermal resistance?

Yes, the SS26FSH specifies R_θJC = 16°C/W in its Thermal Performance section. This value is measured under standardized test conditions (JEDEC 51-14) and reflects heat transfer from junction to case surface. While R_θJL = 18°C/W is more relevant for PCB-mounted designs, R_θJC supports thermal modeling when using external heatsinks or thermal interface materials directly on the case. No separate case dimension drawing is provided in the SS26FSH datasheet.

What packaging and reel quantity is available for SS26FSH?

The SS26FSH is supplied in SOD-128 package on tape-and-reel format, with 14,000 units per reel. This packaging supports high-speed automated placement in SMT lines and complies with J-STD-020 Level 1 moisture sensitivity - meaning no dry-pack or baking is required prior to reflow. The marking code "26FSH" appears on the device body, and date code and factory code follow standard TSC conventions per the Marking Diagram in the SS26FSH datasheet.
