Product details
Overview
D2SB40 D2G from Taiwan Semiconductor is a 2A, 400V rated standard bridge rectifier in GBL package, configured as a quad diode arrangement for full-wave AC-to-DC conversion. It delivers 80A non-repetitive surge current capability, 1.1V max forward voltage at 2A, and operates up to 150°C junction temperature-used in compact AC/DC adapters and LED driver input stages.
For engineers reviewing the D2SB40 D2G datasheet, D2SB40 D2G pinout, D2SB40 D2G application, or D2SB40 D2G equivalent, key selection criteria include VRRM=400V, IFSM=80A, RθJL=10°C/W, RoHS/halogen-free compliance, and AEC-Q101 qualification availability (D2SB40H variant).
Technical Context
The D2SB40 D2G integrates four silicon PN-junction diodes in a single-phase bridge configuration with common-cathode and common-anode terminals. Its GBL package provides UL 94V-0 mold compound, matte tin-plated leads compliant with J-STD-002 solderability, and meets JESD201 Class 2 whisker resistance.
Thermally, it features 10°C/W junction-to-lead resistance and 47°C/W junction-to-ambient resistance. Electrical behavior includes 10µA max reverse leakage at 25°C and 500µA at 125°C, with forward voltage clamped to ≤1.1V under 2A DC load at 25°C.

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU4K (ON Semiconductor) | Same 400V VRRM, 2A IF, but GBU package (larger footprint, higher RθJA = 55°C/W) | Less suitable for space-constrained PCBs; requires larger thermal pad area | Select when legacy GBU footprint compatibility is required over thermal optimization |
| DB104S (Diotec) | 400V VRRM, 1A IF (half the current rating); smaller DO-15 package, no AEC-Q101 option | Limited to sub-12W adapters; not recommended for industrial 2A continuous loads | Choose only for low-power, cost-driven replacements where derating to 1A is acceptable |
Compared with GBU4K and DB104S, the D2SB40 D2G offers superior thermal performance (RθJL = 10°C/W), AEC-Q101 qualification path, and optimized GBL footprint for high-density layouts-making it preferred for 2A industrial and automotive-adjacent designs.

FAQ
What is the peak repetitive reverse voltage rating of the D2SB40 D2G?
The D2SB40 D2G has a peak repetitive reverse voltage (VRRM) rating of 400 V. This value is fixed for the D2SB40 variant and reflects its ability to block reverse voltage across each internal diode during the non-conducting half-cycle. It is verified per the manufacturer's K2103 datasheet revision and applies under standard test conditions (TA = 25°C).
Does the D2SB40 D2G meet automotive reliability standards?
The D2SB40 D2G itself is not AEC-Q101 qualified; however, the pin-compatible D2SB40H variant is explicitly qualified to AEC-Q101. Engineers requiring automotive-grade reliability must specify D2SB40H-not D2SB40 D2G-for under-hood or lighting module applications where stress testing per AEC-Q101 is mandatory.
What is the thermal resistance from junction to lead for the D2SB40 D2G?
The D2SB40 D2G has a junction-to-lead thermal resistance (RθJL) of 10°C/W. This parameter is measured under specified test conditions and enables accurate thermal modeling when the device is mounted on a PCB with copper thermal pads or clipped to an external heatsink-critical for maintaining TJ ≤ 150°C in continuous 2A operation.
Can the D2SB40 D2G replace the D2SB20 in an existing design?
The D2SB40 D2G can replace the D2SB20 only if the circuit's peak reverse voltage does not exceed 400 V and thermal design accommodates identical 2A/80A ratings. Since both share the same GBL package, pinout, and thermal specs, the swap is mechanically and electrically feasible-but verify that the higher 400V rating introduces no unintended stress on downstream capacitors or controllers.
What packaging and marking information applies to the D2SB40 D2G?
The D2SB40 D2G is supplied in GBL package with matte tin-plated leads, packed 25 units per tube. Marking includes "D2SB40" as the device code, "G" for green compound, followed by date and factory codes. Polarity is indicated on the top surface per the standard GBL marking diagram in the K2103 datasheet.
