Product details
Overview
D2SB20 D2G from Taiwan Semiconductor is a 2A, 200V repetitive peak reverse voltage (VRRM) standard quad bridge rectifier in GBL package, featuring 80A surge capability (IFSM), 10°C/W junction-to-lead thermal resistance, and AEC-Q101 qualification option - used in AC/DC front-end stages of compact SMPS and LED drivers.
For engineers reviewing the D2SB20 D2G datasheet, D2SB20 D2G pinout, D2SB20 D2G application, or D2SB20 D2G equivalent, key selection factors include verified VRRM = 200V, IF = 2A continuous rating, GBL mechanical outline compliance, UL Recognized File # E-326243, and halogen-free construction per IEC 61249-2-21.
Technical Context
The D2SB20 D2G integrates four silicon diodes in a single-phase bridge configuration with common-cathode and common-anode terminals, enabling full-wave rectification without external interconnects. Its GBL package provides 47°C/W junction-to-ambient thermal resistance and meets UL 94V-0 flammability requirements.
Designed for high-reliability industrial and automotive-grade power conversion, it supports 150°C maximum junction temperature, passes JESD201 Class 2 whisker testing, and delivers ≤1.1V forward voltage per diode at 2A and 25°C - critical for efficiency in space-constrained adapters and lighting ballasts.
Key Specifications

| IF | 2 A - Continuous average forward current per device; sets thermal design baseline for PCB copper area and heatsinking. |
| IFSM | 80 A - Peak non-repetitive surge current (8.3 ms half-sine); determines robustness against line transients and inrush events. |
| RθJL | 10 °C/W - Junction-to-lead thermal resistance; enables direct thermal coupling to PCB copper pour or heatsink via lead frame. |
| VF (per diode) | ≤1.1 V @ 2A, 25°C - Forward voltage drop per diode under rated load; directly impacts conduction loss and system efficiency. |
| IR (per diode) | ≤10 µA @ 200V, 25°C - Reverse leakage current per diode; affects standby power and high-impedance sensing integrity. |
| TJ max | +150 °C - Maximum allowable junction temperature; defines safe operating area under sustained load and ambient conditions. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU2K (ON Semiconductor) | Same 2A/200V rating, but GBU package (larger footprint, higher RθJA = 55°C/W). | Preferred where legacy GBU layout exists; less suitable for ultra-compact designs. | Select when reusing existing GBU footprints or requiring wider availability across distributors. |
| DB102 (Diotec) | 2A/100V VRRM; lower voltage rating limits use to 115VAC-only systems. | Restricted to North American line-powered equipment without universal input requirement. | Choose only for cost-sensitive 115VAC-only applications where 200V margin is unnecessary. |
Compared with GBU2K and DB102, the D2SB20 D2G offers superior thermal performance (RθJL = 10°C/W vs. ~15°C/W for GBU2K), smaller GBL footprint, and AEC-Q101 qualification path - making it optimal for space-constrained, thermally demanding, or automotive-adjacent industrial power supplies.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for D2SB20 D2G?
The D2SB20 D2G has a VRRM of 200 V, confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version K2103). This rating ensures reliable operation under 230 VAC line conditions with standard safety margins and transient overvoltage allowances. The "20" in the part number explicitly denotes the 200 V rating, consistent across the D2SBxx family.
Is D2SB20 D2G RoHS and halogen-free compliant?
Yes, D2SB20 D2G is RoHS compliant and halogen-free per IEC 61249-2-21, as stated in the FEATURES section of the Taiwan Semiconductor datasheet. The molding compound is UL 94V-0 rated, and terminals are matte tin-plated to meet J-STD-002 solderability requirements - all verified in the Mechanical Data and Ordering Information sections.
Does D2SB20 D2G have AEC-Q101 qualification?
The base D2SB20 D2G is not AEC-Q101 qualified, but the variant D2SB20H is explicitly listed as AEC-Q101 qualified in the Ordering Information table. The "H" suffix denotes automotive-grade qualification, while D2SB20 D2G retains industrial-grade specifications and marking (D2G = Green compound, no "H"). No AEC-Q101 claim applies to the D2G suffix.
What is the thermal resistance from junction to lead (RθJL) for D2SB20 D2G?
The D2SB20 D2G has a typical junction-to-lead thermal resistance (RθJL) of 10°C/W, specified in the Thermal Performance section of the datasheet. This value enables efficient heat transfer from the die through the lead frame to PCB copper, supporting higher power density than alternatives like GBU-series rectifiers with higher RθJL.
What does the "D2G" suffix mean in D2SB20 D2G?
The "D2G" suffix in D2SB20 D2G indicates Green compound (halogen-free molding material) and standard industrial qualification - distinct from the "H" suffix used for AEC-Q101 variants. Per the Marking Diagram on page 4 of the datasheet, "G" denotes green compound, and "D2" is the internal process code; no functional or electrical difference exists between D2G and non-suffix variants beyond material compliance.
