Taiwan Semiconductor Corporation SS210L

Overview

SS210L from Taiwan Semiconductor is a 2 A, 100 V Schottky barrier surface-mount rectifier in Sub SMA package, featuring 0.85 V forward voltage at 2 A and 100 µA reverse leakage at rated VR and 25°C, designed for high-efficiency DC-DC converters and AC-DC adapters.

For engineers reviewing the SS210L datasheet, SS210L pinout, SS210L application, or SS210L equivalent, key selection criteria include its 100 V repetitive peak reverse voltage, 50 A non-repetitive surge rating, 125°C maximum junction temperature, low VF trade-off versus higher-voltage variants, and Sub SMA mechanical compatibility with automated SMT assembly.

Technical Context

The SS210L implements a single-die Schottky junction optimized for low conduction loss in medium-voltage switching rectification. Its 100 V V_RRM and 0.85 V V_F at 2 A reflect a balanced design between blocking capability and forward drop, distinct from lower-V_RRM (e.g., SS24L) and higher-V_RRM (e.g., SS215L) variants in the same family.

Thermal performance is defined by 17°C/W junction-to-lead resistance and 75°C/W junction-to-ambient resistance. It meets JESD201 Class 2 whisker resistance and J-STD-020 Level 1 moisture sensitivity, supporting lead-free reflow without preconditioning.

FAQ

What is the maximum junction temperature rating for the SS210L?

The SS210L has a maximum junction temperature (T_J) rating of 125°C, as specified in the Absolute Maximum Ratings table. This allows operation in ambient temperatures up to 85°C with appropriate PCB copper area for heat dissipation. Derating begins above 25°C per the Forward Current Derating Curve (Fig.1), and the device must not exceed 125°C under any steady-state or transient condition. The SS210L datasheet confirms this limit applies specifically to the SS210L variant.

Is the SS210L RoHS and halogen-free compliant?

Yes, the SS210L is RoHS compliant per EU Directive 2011/65/EU and halogen-free according to IEC 61249-2-21. These compliance statements appear in the FEATURES section of the official Taiwan Semiconductor SS22L–SS215L datasheet (Version O2103). The Sub SMA molding compound and matte tin-plated leads meet both requirements, and no exemptions are applied. SS210L is certified for green electronics manufacturing.

What does the marking code '20L' indicate on the SS210L device body?

The marking code '20L' on the SS210L indicates its voltage rating: '20' corresponds to 100 V V_RRM, and 'L' denotes the Sub SMA package variant. This coding aligns with the ordering convention in the datasheet's Ordering Information table, where 'x' in SS2xL maps to voltage (e.g., SS22L = 20 V, SS210L = 100 V). The 'L' suffix distinguishes it from standard SMA versions like SS210.

How does the SS210L's forward voltage compare to other devices in the SS2xL family?

The SS210L has a typical forward voltage of 0.85 V at 2 A and 25°C-higher than lower-voltage variants (e.g., SS24L: 0.50 V) but lower than SS215L (0.95 V). This reflects the inherent Schottky trade-off: higher V_RRM requires wider bandgap metallization, increasing V_F. The SS210L's 0.85 V value is confirmed in the Electrical Specifications table and is specific to the SS210L, not interpolated.

Can the SS210L replace the SS210 in an existing design?

The SS210L can replace the SS210 electrically but requires PCB pad revision due to its Sub SMA package-smaller footprint and shorter leads than standard SMA. While V_RRM, I_F, and V_F match, the Sub SMA outline (per Package Outline Dimensions drawing) demands updated stencil and placement files. Thermal performance differs slightly (R_θJA = 75°C/W vs. ~65°C/W for SS210), so thermal validation is recommended. SS210L is not a drop-in replacement without layout changes.
