Taiwan Semiconductor Corporation D2SB05H

Overview

D2SB05H from Taiwan Semiconductor is a 2A, 50V standard bridge rectifier in GBL package, featuring AEC-Q101 qualification, 80A surge current capability, and 1.1V max forward voltage at 2A - used in automotive-grade AC/DC front-ends and compact SMPS adapters.

For engineers reviewing the D2SB05H datasheet, D2SB05H pinout, D2SB05H application, or D2SB05H equivalent, key selection criteria include peak reverse voltage (50V), junction-to-lead thermal resistance (10°C/W), AEC-Q101 compliance status, and GBL package compatibility with high-density PCB layouts.

Technical Context

The D2SB05H integrates four silicon diodes in a single-phase full-wave bridge configuration, rated for continuous 2A average forward current and 80A non-repetitive surge (8.3ms half-sine). Its GBL package provides UL 94V-0 mold compound and matte tin-plated leads compliant with J-STD-002 solderability.

Thermal performance is defined by R_θJL = 10°C/W and R_θJA = 47°C/W, enabling operation up to +150°C junction temperature. Reverse leakage remains ≤10µA at 25°C and ≤500µA at 125°C under rated 50V reverse bias.

FAQ

What is the peak repetitive reverse voltage rating for D2SB05H?

The D2SB05H has a peak repetitive reverse voltage (V_RRM) rating of 50 V. This value is specified in the Absolute Maximum Ratings table and defines the maximum AC voltage the device can block during normal operation without entering avalanche breakdown. It applies across the full operating temperature range and is validated per JEDEC standards.

Is D2SB05H qualified to AEC-Q101, and what does that mean for automotive use?

Yes, D2SB05H is AEC-Q101 qualified - confirmed by the "H" suffix in its ordering code and explicitly stated in the FEATURES section. This qualification means the D2SB05H has passed accelerated stress tests including high-temperature operating life, temperature cycling, and unbiased highly accelerated stress testing, ensuring suitability for automotive power electronics such as body control modules and infotainment power supplies.

What is the forward voltage drop of D2SB05H at rated current?

The D2SB05H exhibits a maximum forward voltage drop (V_F) of 1.1 V per diode at 2 A forward current and 25°C junction temperature. This value is measured under pulsed conditions (PW = 0.3 ms) and directly impacts conduction losses in the rectifier stage - lower V_F improves system efficiency, especially in thermally limited adapter designs.

Does D2SB05H have UL recognition, and what file number is assigned?

Yes, D2SB05H is UL Recognized under File # E-326243. This certification confirms compliance with UL 60950-1 and UL 62368-1 for insulation coordination, flammability (UL 94V-0), and electrical safety - enabling direct use in end-equipment seeking UL/CSA safety approval without additional component-level evaluation.

What package type does D2SB05H use, and how are its terminals arranged?

D2SB05H uses the GBL package - a single-in-line, 4-terminal molded plastic case with matte tin-plated leads. Terminals are linearly arranged as AC1–AC2–+––, where AC1 and AC2 accept the AC input, and + and – deliver the full-wave rectified DC output. The GBL footprint is optimized for high-density PCB layouts and meets J-STD-002 solderability requirements.
