Product details
Overview
DBLS207GHC1G from Taiwan Semiconductor is a 2 A, 1000 V repetitive peak reverse voltage (VRRM) standard bridge rectifier in DBLS package, featuring 50 A peak surge current (IFSM), 1.15 V forward voltage at 2 A/25°C, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the DBLS207GHC1G datasheet, DBLS207GHC1G pinout, DBLS207GHC1G application, or DBLS207GHC1G equivalent, key selection criteria include rated reverse voltage margin, thermal resistance (RθJL = 15 °C/W), surge robustness (I2t = 10.3 A2s), and halogen-free, RoHS-compliant construction for high-reliability power conversion designs.
Technical Context
This quad-configuration bridge rectifier integrates four silicon diodes in a single molded DBLS package with matte tin-plated leads. It operates across –55°C to +150°C junction temperature range and delivers stable conduction under 8.3 ms half-sine surge conditions.
Designed for high-density PCB mounting, it meets UL 94V-0 flammability rating and JESD201 Class 2 whisker resistance. Its 1.15 V typical forward voltage per diode at 2 A/25°C enables efficient AC-to-DC conversion in compact power supplies.

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU6K (ON Semiconductor) | Same 2 A / 1000 V rating; GBU package (larger footprint, higher RθJA = 50 °C/W) | Requires larger PCB area and more thermal relief; not AEC-Q101 qualified | Preferred where cost is primary and automotive qualification is unnecessary |
| MB10F (Vishay) | 2 A / 1000 V; MB package (smaller than DBLS); VF = 1.1 V typ., but no AEC-Q101 or halogen-free certification | Limited to commercial temperature range (–55°C to +125°C); lacks moisture level 1 rating | Suitable for space-constrained consumer adapters where automotive compliance is not required |
Compared with GBU6K and MB10F, DBLS207GHC1G uniquely combines AEC-Q101 qualification, moisture level 1, halogen-free construction, and optimized thermal resistance (15 °C/W) - making it the only choice for automotive auxiliary supplies and sealed industrial power modules demanding long-term reliability.

FAQ
What is the peak repetitive reverse voltage (VRRM) rating of DBLS207GHC1G?
The DBLS207GHC1G has a VRRM rating of 1000 V, meaning it can block up to 1000 V of reverse voltage repeatedly without breakdown. This rating is confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version J2103), and corresponds to the "207" in the part number - where '7' denotes the 1000 V variant within the DBLS201G–DBLS209G series. The device maintains this rating across its full operating junction temperature range.
Is DBLS207GHC1G suitable for automotive applications?
Yes, DBLS207GHC1G is AEC-Q101 qualified, as indicated by the "H" suffix in the ordering code and explicitly stated in the FEATURES section of the datasheet. It undergoes stress testing for temperature cycling, humidity, and mechanical shock per AEC-Q101 standards. Its –55°C to +150°C junction temperature range, halogen-free construction, and moisture sensitivity level 1 make DBLS207GHC1G appropriate for automotive auxiliary power supplies and onboard charger subsystems.
What does the "C1G" suffix in DBLS207GHC1G signify?
The "C1G" suffix in DBLS207GHC1G indicates tape-and-reel packaging: "C1" denotes 1500 units per reel, and "G" confirms green (halogen-free) molding compound per IEC 61249-2-21. This matches the Ordering Information table in the Taiwan Semiconductor datasheet, which specifies DBLS2xGH for AEC-Q101 versions and notes that "G" stands for green compound. The base part DBLS207GH already includes AEC-Q101 qualification; C1G adds packaging detail.
What is the forward voltage (VF) of DBLS207GHC1G under typical operating conditions?
DBLS207GHC1G exhibits a typical forward voltage of 1.15 V per diode at IF = 2 A and TJ = 25°C, as specified in the Electrical Specifications table. This value is measured under pulsed conditions (PW = 0.3 ms) and represents conduction loss across one diode in the bridge. Total bridge drop is ~2.3 V at full load, directly impacting efficiency and thermal design in 20–50 W power supplies.
How does the thermal performance of DBLS207GHC1G compare to standard GBU-package bridges?
DBLS207GHC1G offers superior thermal performance versus legacy GBU packages: its junction-to-lead thermal resistance (RθJL) is 15 °C/W, compared to ~25–30 °C/W for typical GBU devices. This lower RθJL enables more effective heat transfer from the die to the PCB copper pour, reducing junction temperature rise by up to 15°C under identical 2 A DC load - critical for reliability in sealed or high-ambient-temperature applications using DBLS207GHC1G.
