Product details
Overview
RDBLS207GH 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 - deployed in automotive-grade SMPS, LED drivers, and AC/DC adapters requiring high-reliability rectification under thermal stress.
For engineers reviewing the RDBLS207GH datasheet, RDBLS207GH pinout, RDBLS207GH application, or RDBLS207GH equivalent, key selection criteria include its AEC-Q101 qualification status, 1000 V VRRM rating, 22 °C/W junction-to-lead thermal resistance, and DBLS surface-mount footprint compatibility with high-density PCB layouts.
Technical Context
This quad-configuration bridge rectifier integrates four fast recovery diodes in a single DBLS molded plastic package, enabling full-wave AC-to-DC conversion without external interconnects. Its 300 ns trr and 1.15 V max VF at 2 A support high-frequency switching efficiency in >60 kHz SMPS topologies.
The device operates across –55 °C to +150 °C junction temperature range, with JESD201 Class 2 whisker resistance and moisture sensitivity level 1 (per J-STD-020), confirming suitability for reflow-soldered automotive electronics assembly processes.

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU2K | Same 2 A / 1000 V rating but standard GBU package (larger footprint, higher RθJA = 70 °C/W); not AEC-Q101 qualified | Targeted at cost-sensitive industrial adapters, not automotive or high-reliability designs | Select when AEC-Q101 is unnecessary and board space permits larger through-hole or GBU-SMD variants |
| DF10M | 2 A / 1000 V, DO-214AA package, 500 ns trr, no AEC-Q101; lower IFSM (30 A) | Suitable for low-frequency (<20 kHz) linear or quasi-resonant supplies with relaxed surge demands | Choose for legacy designs using SMB/SMA footprints where DBLS layout change is prohibitive |
Compared with GBU2K and DF10M, the RDBLS207GH uniquely combines AEC-Q101 qualification, 300 ns fast recovery, and DBLS thermal performance - making it the only option for thermally constrained, automotive-compliant bridge rectification where both reliability and switching efficiency are mandatory.

FAQ
What does the "H" suffix in RDBLS207GH signify?
The "H" suffix in RDBLS207GH explicitly denotes AEC-Q101 qualification - confirmed by Taiwan Semiconductor's test reports covering HTSL, temperature cycling, and biased HAST. Unlike the base RDBLS207G, the RDBLS207GH undergoes additional automotive-specific stress screening and lot-level traceability, making it suitable for safety-critical automotive power modules where zero-defect reliability is mandated.
Is RDBLS207GH pin-compatible with other DBLS-series rectifiers?
Yes - RDBLS207GH shares identical DBLS package dimensions, terminal layout (AC1/AC2/+/-), and solder pad requirements with all RDBLSxxxG/H variants. The marking code "RDBLS207GH" appears on the top surface, and polarity is indicated by a cathode bar adjacent to the "–" terminal, ensuring unambiguous orientation during automated placement.
What is the maximum allowable PCB copper area for thermal enhancement of RDBLS207GH?
Taiwan Semiconductor recommends ≥80 mm² of 2-oz copper connected directly to each of the four terminals (AC1, AC2, +, –) to achieve the published RθJL = 22 °C/W. Larger copper areas further reduce thermal resistance, but diminishing returns occur beyond 120 mm² per terminal; thermal simulation is advised for designs exceeding 1.8 W total dissipation.
Does RDBLS207GH meet halogen-free requirements per IEC 61249-2-21?
Yes - RDBLS207GH uses halogen-free molding compound compliant with IEC 61249-2-21, verified by material certification and third-party testing. This eliminates brominated flame retardants (BFRs) and chlorinated flame retardants (CFRs), supporting RoHS compliance and environmentally responsible end-of-life processing in consumer and automotive electronics.
Can RDBLS207GH replace GBU2K in existing designs without layout changes?
No - RDBLS207GH uses the DBLS surface-mount package (5.0 × 4.0 × 1.5 mm), while GBU2K uses the larger GBU through-hole or GBU-SMD package (13.0 × 10.0 × 4.0 mm). Direct replacement requires PCB redesign to accommodate the smaller footprint, revised stencil aperture, and updated pick-and-place coordinates; however, electrical parameters remain functionally interchangeable where AEC-Q101 is not required.
