Taiwan Semiconductor Corporation SBS26

Overview

SBS26 from Taiwan Semiconductor is a 2A, 60V repetitive peak reverse voltage quad Schottky bridge rectifier in ABS package, featuring 50A peak forward surge current, 0.70V max forward voltage at 2A/25°C, and 50µA max reverse current at rated VR - used in PoE power delivery and LED lighting front-end rectification.

For engineers reviewing the SBS26 datasheet, SBS26 pinout, SBS26 application, or SBS26 equivalent, key selection criteria include its 60V V_RRM, quad configuration for full-wave bridge integration, AEC-Q101 qualification option (SBS26H), thermal resistance (R_θJL = 30°C/W), and moisture sensitivity level 1 compliance.

Technical Context

The SBS26 integrates four Schottky diodes in a single ABS-packaged bridge configuration, enabling compact full-wave AC-to-DC conversion without external interconnects. Its 60V V_RRM rating supports higher-input PoE++ systems and 48V industrial lighting rails.

Thermal performance is defined by R_θJL = 30°C/W and R_θJA = 75°C/W, with junction temperature range from –55°C to +150°C. Reverse leakage is specified at 50µA max per diode at rated VR and 25°C.

FAQ

What is the maximum repetitive peak reverse voltage (V_RRM) for the SBS26?

The SBS26 has a maximum repetitive peak reverse voltage (V_RRM) of 60 V, as confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version C2103). This rating applies per diode within the quad bridge configuration and defines the highest continuous reverse voltage the device can block without breakdown. It is 20 V higher than the SBS24 (40 V) and 10 V higher than the SBS25 (50 V), making the SBS26 suitable for 48–60 V system rails.

Does the SBS26 have AEC-Q101 qualification?

The base SBS26 is not AEC-Q101 qualified; however, the variant SBS26H is explicitly listed in the Ordering Information as AEC-Q101 qualified. The "H" suffix denotes automotive-grade screening and testing per AEC-Q101 standards. For automotive applications requiring qualification, designers must specify SBS26H - the standard SBS26 does not carry this certification and should not be used in automotive contexts unless fully requalified.

What is the forward voltage (V_F) specification for the SBS26 at rated current?

The SBS26 has a maximum forward voltage (V_F) of 0.70 V per diode at I_F = 2 A and T_J = 25°C, as specified in the Electrical Specifications table. This value is measured under pulsed conditions (PW = 0.3 ms) and reflects typical conduction loss in high-frequency switching applications. At elevated junction temperatures (e.g., 125°C), V_F decreases slightly due to Schottky diode characteristics, but the 0.70 V max remains the design-limiting value for thermal calculations.

What package type and mounting compatibility does the SBS26 use?

The SBS26 uses the ABS package - a surface-mount molded plastic case with matte tin-plated gull-wing leads. It complies with J-STD-002 for solderability and meets JESD201 Class 2 whisker resistance. The ABS outline matches industry-standard pad layouts for SO-8–equivalent footprints, and its moisture sensitivity level (MSL) is Level 1, permitting unlimited exposure before reflow. No special handling or baking is required prior to assembly.

How does the SBS26 compare to the SBS24 and SBS25 in terms of reverse leakage current?

The SBS26 specifies a maximum reverse current (I_R) of 50 µA per diode at rated V_R and 25°C, which is half the 100 µA limit of the SBS24 and SBS25. This lower leakage improves performance in high-impedance bias networks and low-power standby modes. The reduction correlates with the higher V_RRM design and tighter process control for the 60V variant, as confirmed in the Electrical Specifications table across all three versions.
