Product details
Overview
DBLS209GHC1G from Taiwan Semiconductor is a 2 A, 1400 V repetitive peak reverse voltage (VRRM) standard bridge rectifier in DBLS surface-mount package, featuring 50 A peak forward surge current (IFSM), 1.30 V max forward voltage at 2 A and 25°C, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the DBLS209GHC1G datasheet, DBLS209GHC1G pinout, DBLS209GHC1G application, or DBLS209GHC1G equivalent, key selection considerations include its 1400 V VRRM rating, 15 °C/W junction-to-lead thermal resistance, quad configuration, UL Recognized status (E-326854), and moisture sensitivity level 1 compliance per J-STD-020.
Technical Context
This device integrates four silicon diodes in a single-phase full-wave bridge configuration, enabling AC-to-DC conversion without external interconnection. Its DBLS molded plastic package supports automated SMT assembly and provides UL 94V-0 flammability rating with matte tin-plated leads compliant to J-STD-002 solderability and JESD 201 Class 2 whisker resistance.
Thermal performance is defined by RθJL = 15 °C/W and RθJA = 40 °C/W, supporting operation across -55°C to +150°C junction temperature range. Reverse leakage remains ≤2 µA at 25°C and ≤500 µA at 125°C under rated VRRM, ensuring stable blocking in high-temperature SMPS environments.

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay GBU15K | Same 2 A / 1400 V rating, but GBU through-hole package; higher RθJA (50 °C/W) and no AEC-Q101 qualification | Preferred for prototyping or legacy through-hole designs; unsuitable for automotive or high-density SMT layouts | Select when mechanical mounting constraints require axial leads or when AEC-Q101 is not required |
| ON Semiconductor GBPC214 | 2 A / 1400 V, but GBPC case (larger footprint); VF = 1.1 V typ (lower loss), no AEC-Q101, UL Recognized but different file number | Used in cost-sensitive industrial adapters where thermal margin exceeds requirement and space allows larger package | Select when lower conduction loss is prioritized over footprint size and automotive qualification is unnecessary |
Compared with GBU15K and GBPC214, DBLS209GHC1G uniquely combines AEC-Q101 qualification, DBLS surface-mount form factor, and UL E-326854 recognition-making it the only option among the three qualified for automotive SMT power conversion with certified safety and moisture resilience.
