Product details

Overview

SBS36 from Taiwan Semiconductor is a 3A, 60V repetitive peak reverse voltage Schottky bridge rectifier in ABS package with quad configuration, rated for 150°C maximum junction temperature and 80A non-repetitive surge current, used in PoE power delivery and LED lighting front-end rectification.

For engineers reviewing the SBS36 datasheet, SBS36 pinout, SBS36 application, or SBS36 equivalent, key selection criteria include its 60V V_RRM, 0.70V max forward voltage at 3A/25°C, AEC-Q101 qualification option (SBS36H), moisture sensitivity level 1, and UL 94V-0 compliant ABS molding compound.

Technical Context

The SBS36 integrates four Schottky diodes in a single-phase bridge configuration, enabling full-wave rectification without external interconnects. Its thermal resistance values-R_θJL = 41°C/W and R_θJA = 83°C/W-support high-current operation up to 3A continuous under natural convection in compact layouts.

Electrical behavior is defined by two critical operating points: at TJ = 25°C, VF ≤ 0.70V (IF = 3A), and at TJ = 150°C, IR ≤ 10mA (VR = 60V). The device exhibits no specified reverse leakage at TJ = 100°C or 125°C for SBS36, distinguishing it from SBS34's published IR values at those temperatures.

Equivalent & Alternatives

The following parts are listed as comparable options for similar Schottky bridge rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
Vishay VS-36MB60A	60V V_RRM, 3.6A I_F, TO-220AC package, R_θJA = 50°C/W, no AEC-Q101 option	Higher current rating but larger footprint and lower thermal efficiency; requires heatsinking above 2A	Select when higher I_F margin is needed and board space permits TO-220 mounting.
ON Semiconductor MB3660	60V V_RRM, 3A I_F, ABS package, VF = 0.72V max, no AEC-Q101 variant listed	Identical package and current rating; slightly higher VF increases conduction loss by ~3% at full load	Choose when sourcing from ON Semi distribution channels is preferred and AEC-Q101 is not required.

Compared with VS-36MB60A and MB3660, the SBS36 offers superior thermal performance in ABS (R_θJL = 41°C/W vs. ~55–60°C/W typical for competing ABS bridges) and unique AEC-Q101 qualification via SBS36H, making it optimal for space-constrained, high-reliability PoE and automotive-adjacent applications.

FAQ

What is the maximum junction temperature rating for SBS36?

The SBS36 has a maximum junction temperature (T_J) rating of +150°C, as specified in the Absolute Maximum Ratings table. This allows operation in thermally demanding environments such as enclosed LED drivers or industrial power supplies where ambient temperatures exceed 85°C. The SBS36 maintains full electrical specifications up to this limit, unlike SBS34 which is rated only to +125°C.

Does SBS36 have AEC-Q101 qualification?

The base SBS36 is not AEC-Q101 qualified, but the variant SBS36H is explicitly listed as AEC-Q101 qualified in the Ordering Information section. SBS36H shares identical electrical and thermal specifications with SBS36 but undergoes additional stress testing and lot-level validation required for automotive-grade components. Always specify "H" suffix when AEC-Q101 compliance is required.

What is the forward voltage specification for SBS36 at 3A and 25°C?

The SBS36 has a maximum forward voltage (V_F) of 0.70 V at I_F = 3 A and T_J = 25°C, per the Electrical Specifications table. This value is measured per diode within the bridge, under pulsed conditions (PW = 0.3 ms). At higher junction temperatures, V_F decreases slightly due to Schottky diode physics, but system-level conduction loss calculations should use the 0.70 V max value for worst-case thermal design.

How does SBS36 differ from SBS34 in terms of reverse voltage rating?

SBS36 is rated for 60 V repetitive peak reverse voltage (V_RRM), while SBS34 is rated for 40 V V_RRM. This 20 V difference defines their respective application boundaries: SBS36 supports higher-input-voltage designs such as 57 V PoE systems or 230 VAC-fed LED drivers with wide input tolerances, whereas SBS34 suits 12–24 VAC or lower-voltage auxiliary supplies.

What package type and lead finish does SBS36 use?

SBS36 uses the ABS package-a surface-mount molded plastic case with gull-wing leads-and features matte tin-plated terminals that comply with J-STD-002 for solderability. The ABS package meets UL 94V-0 flammability rating and JESD 201 Class 2 whisker resistance, supporting reliable reflow assembly and long-term interconnect integrity in industrial and automotive applications.
