Product details
Overview
DBLS206GH from Taiwan Semiconductor is a 2 A, 800 V repetitive peak reverse voltage (VRRM) standard quad bridge rectifier in DBLS surface-mount package, featuring 50 A peak surge current (IFSM), 1.15 V max forward voltage at 2 A, and AEC-Q101 qualification for automotive-grade reliability - used in AC/DC front-end stages of compact switching mode power supplies.
For engineers reviewing the DBLS206GH datasheet, DBLS206GH pinout, DBLS206GH application, or DBLS206GH equivalent, key selection considerations include its 800 V VRRM, AEC-Q101 qualification status, 15 °C/W junction-to-lead thermal resistance, UL Recognized (E-326854), and moisture sensitivity level 1 compliance.
Technical Context
This device integrates four diodes in a single-phase full-wave bridge configuration with common-cathode and common-anode terminals externally accessible. Its DBLS molded plastic package supports reflow soldering per J-STD-002, with matte tin-plated leads and UL 94V-0 rated compound.
Thermal performance is defined by RθJL = 15 °C/W and RθJA = 40 °C/W, enabling sustained 2 A average forward current (IF) up to 150 °C junction temperature. Reverse leakage remains ≤2 µA at 25 °C and ≤500 µA at 125 °C under rated VR.

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU8K (ON Semiconductor) | 8 A rating, 800 V VRRM, GBU through-hole package, higher IF but larger footprint and no AEC-Q101 | Suitable for higher-power industrial supplies where board space and automotive qualification are not constraints | Select when >2 A average current is needed and surface-mount is not mandatory |
| DF08MA (Vishay) | 2 A, 800 V, same DBLS footprint, AEC-Q101 qualified, but VF = 1.25 V (max) - 0.1 V higher than DBLS206GH | Drop-in replacement in automotive lighting where slightly higher conduction loss is acceptable | Choose if dual-sourcing is required and minor efficiency trade-off is tolerable |
Compared with GBU8K and DF08MA, DBLS206GH offers the lowest forward voltage (≤1.15 V) among AEC-Q101-qualified 2 A, 800 V DBLS-package bridges, optimizing thermal performance in space-constrained automotive and industrial designs.

FAQ
What is the peak repetitive reverse voltage rating for DBLS206GH?
The DBLS206GH has a repetitive peak reverse voltage (VRRM) rating of 800 V. This value is specified per diode within the bridge and defines the maximum instantaneous reverse voltage the device can block repeatedly without breakdown. It is confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet Version J2103.
Is DBLS206GH qualified to AEC-Q101 standards?
Yes, DBLS206GH is AEC-Q101 qualified - the "H" suffix explicitly denotes this qualification. Test evidence includes temperature cycling, high-temperature reverse bias (HTRB), and unbiased highly accelerated stress test (uHAST), all performed per AEC-Q101 Rev D. This makes DBLS206GH suitable for automotive power electronics where reliability under thermal and electrical stress is critical.
What is the forward voltage drop of DBLS206GH at rated current?
At IF = 2 A and TJ = 25 °C, the maximum forward voltage (VF) per diode in DBLS206GH is 1.15 V. This value is measured under pulsed conditions (PW = 0.3 ms) and directly impacts conduction losses and thermal design. The actual VF decreases with lower junction temperature and increases at elevated TJ.
Does DBLS206GH require baking before reflow soldering?
No, DBLS206GH does not require baking prior to reflow. It is rated Moisture Sensitivity Level 1 (MSL-1) per J-STD-020, meaning it can be stored indefinitely at ≤30 °C/60% RH and placed directly into standard SMT reflow profiles without preconditioning or dry-pack handling - simplifying manufacturing logistics and reducing process risk.
What is the thermal resistance from junction to lead for DBLS206GH?
The junction-to-lead thermal resistance (RθJL) of DBLS206GH is 15 °C/W. This parameter quantifies the thermal impedance between the silicon die and the package leads, enabling effective heat transfer to the PCB copper pour. It is measured under steady-state conditions and supports thermal modeling for layouts using thermal vias and copper mass under the DBLS footprint.
