Product details
Overview
RDBLS207G from Taiwan Semiconductor is a 2 A, 1000 V fast recovery quad bridge rectifier in DBLS package, featuring 300 ns reverse recovery time, 50 A peak surge current capability, and AEC-Q101 qualification option (RDBLS207GH); used in high-efficiency SMPS and lighting ballasts where compact size and thermal robustness are critical.
For engineers reviewing the RDBLS207G datasheet, RDBLS207G pinout, RDBLS207G application, or RDBLS207G equivalent, key selection criteria include repetitive peak reverse voltage (1000 V), forward current rating (2 A), junction-to-lead thermal resistance (22 °C/W), and compliance with JESD201 Class 2 whisker testing and RoHS/halogen-free requirements.
Technical Context
The RDBLS207G integrates four fast recovery diodes in a single DBLS surface-mount package configured as a full-wave bridge. Its 300 ns trr enables high-frequency switching up to 100 kHz in offline SMPS topologies while maintaining low conduction loss via 1.15 V max VF at 2 A and 25 °C.
Thermal performance is defined by RθJL = 22 °C/W and RθJA = 62 °C/W, supporting operation from –55 °C to +150 °C junction temperature. The device meets UL 94V-0 flammability, J-STD-020 moisture sensitivity level 1, and AEC-Q101 stress testing when ordered as RDBLS207GH.

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 2 A / 1000 V rating but GBU through-hole package; trr = 500 ns; RθJA ≈ 45 °C/W | Requires PCB through-hole mounting; less suitable for automated SMT lines | Select when legacy through-hole assembly or higher surge margin (IFSM = 60 A) is prioritized over board space |
| GBL207 (Comchip) | DBLS-compatible footprint; trr = 350 ns; VF = 1.2 V max; no AEC-Q101 variant | Lacks automotive qualification; slightly higher conduction loss at full load | Choose for cost-sensitive consumer lighting where AEC-Q101 is not required |
Compared with GBU2K and GBL207, the RDBLS207G delivers superior thermal performance (RθJL = 22 °C/W), tighter trr control (300 ns), and optional AEC-Q101 qualification-making it optimal for high-density, thermally constrained, or automotive-adjacent power supplies.

FAQ
What is the maximum junction temperature rating for the RDBLS207G?
The RDBLS207G has a maximum junction temperature (TJ) rating of +150 °C, with operational range from –55 °C to +150 °C. This allows deployment in high-ambient environments such as enclosed LED luminaires or industrial control cabinets. Derating curves in the datasheet define allowable forward current versus lead temperature, ensuring safe operation within this thermal envelope. The RDBLS207G maintains specified electrical parameters up to its rated TJ limit.
Does the RDBLS207G have automotive qualification?
The base RDBLS207G is not AEC-Q101 qualified; however, the variant RDBLS207GH is fully AEC-Q101 qualified and shares identical electrical and thermal specifications. The "H" suffix denotes qualification per AEC-Q101 Rev D for stress tests including HTSL, TC, UHAST, and ESD. For automotive body electronics or ADAS auxiliary power modules, RDBLS207GH is the designated qualified version, while RDBLS207G serves general industrial and commercial applications.
What is the reverse recovery time (trr) specification for the RDBLS207G?
The RDBLS207G has a reverse recovery time (trr) of 300 ns, measured under IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A conditions at 25 °C. This fast trr enables efficient operation in high-frequency switching power supplies (e.g., 65–100 kHz flyback converters), minimizing switching losses and associated EMI. The value is guaranteed maximum and confirmed across production lots per TSC's characterization methodology.
How does the DBLS package of the RDBLS207G compare thermally to standard GBU packages?
The DBLS package of the RDBLS207G achieves RθJL = 22 °C/W, significantly lower than typical GBU packages (≈35–45 °C/W), due to optimized internal leadframe design and direct thermal path to PCB copper. This results in ~15–20 °C lower junction temperature at 2 A load compared to equivalent GBU devices under identical board layout. The RDBLS207G's DBLS footprint also enables smaller board area and full SMT compatibility.
Is the RDBLS207G halogen-free and RoHS compliant?
Yes, the RDBLS207G is both halogen-free per IEC 61249-2-21 and RoHS compliant per EU Directive 2011/65/EU. The molding compound contains no brominated or chlorinated flame retardants, and all terminals use matte tin plating meeting J-STD-002 solderability standards. These compliance attributes are verified through material declarations and third-party lab testing, and apply to all standard RDBLS207G production lots.
