Product details
Overview
D2SB05HD2G from Taiwan Semiconductor is a 2A, 50V AEC-Q101-qualified standard bridge rectifier in GBL package, featuring 80A surge current capability, 10°C/W junction-to-lead thermal resistance, and UL Recognized File #E-326243 compliance for automotive-grade power conversion.
For engineers reviewing the D2SB05HD2G datasheet, D2SB05HD2G pinout, D2SB05HD2G application, or D2SB05HD2G equivalent, key selection factors include its 50V repetitive peak reverse voltage, 2A average forward current rating, matte tin-plated solderable leads per J-STD-002, and halogen-free molding compound per IEC 61249-2-21.
Technical Context
This quad-configuration bridge rectifier integrates four silicon diodes in a single GBL package to provide full-wave AC-to-DC conversion without external wiring. Its 150°C maximum junction temperature and -55°C to +150°C storage range support operation in harsh automotive under-hood environments.
The device delivers 1.1V typical forward voltage per diode at 2A and 25°C, with reverse leakage limited to 10µA at rated VR and 25°C. Thermal performance is defined by RθJL = 10°C/W and RθJA = 47°C/W, enabling reliable conduction in compact PCB layouts.

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU2K-E3/51 (Vishay) | Same 2A/50V rating but GBU package (larger footprint, higher RθJA = 50°C/W) | Lacks AEC-Q101 qualification; intended for commercial-grade power supplies | Select when automotive qualification is not required and board space allows larger package |
| DF02M (ON Semiconductor) | 2A/50V, MBM package, no UL file number, RθJL = 12°C/W | Not AEC-Q101 qualified; RoHS compliant but not halogen-free per IEC 61249-2-21 | Choose for cost-sensitive industrial adapters where halogen-free and UL recognition are non-mandatory |

FAQ
What is the peak repetitive reverse voltage rating for D2SB05HD2G?
The D2SB05HD2G has a repetitive peak reverse voltage (VRRM) rating of 50 V. This value is confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version K2103), and defines the maximum AC voltage the device can block across its AC terminals during normal operation without breakdown. Exceeding this voltage risks irreversible avalanche failure.
Is D2SB05HD2G suitable for automotive applications?
Yes, D2SB05HD2G is explicitly AEC-Q101 qualified, as indicated by the "H" suffix in its ordering code and confirmed in the FEATURES section of the Taiwan Semiconductor datasheet. It meets stress test requirements for temperature cycling, humidity bias, and mechanical shock, making it suitable for under-hood and cabin electronics such as body control modules and lighting drivers.
What does the "D2G" suffix mean in D2SB05HD2G?
The "D2G" suffix in D2SB05HD2G indicates green (halogen-free) compound packaging per IEC 61249-2-21, consistent with Taiwan Semiconductor's marking convention shown in the PACKAGE OUTLINE DIMENSIONS page. The "D2" denotes date code format (year-week), and "G" confirms halogen-free molding compound - a requirement for many automotive and eco-regulated applications.
What is the thermal resistance from junction to lead for D2SB05HD2G?
The junction-to-lead thermal resistance (RθJL) for D2SB05HD2G is 10°C/W, as specified in the THERMAL PERFORMANCE section of the Taiwan Semiconductor datasheet. This low value enables efficient heat transfer from the silicon die to the PCB copper through the leads, supporting high-current operation without external heatsinking in GBL-mounted designs.
Does D2SB05HD2G have UL recognition?
Yes, D2SB05HD2G carries UL Recognition under File #E-326243, as stated in the FEATURES section of the official datasheet. This certification verifies compliance with UL 60950-1 and UL 62368-1 for use in end equipment requiring safety agency approval, including power adapters and industrial control systems sold in North America.
