Product details
Overview
DBLS102GH from Taiwan Semiconductor is a 1A, 100V AEC-Q101-qualified standard bridge rectifier in DBLS package, featuring 40A peak surge current (IFSM), 1.1V max forward voltage at 1A, and 2µA max reverse leakage at 25°C. It serves as AC-to-DC conversion core in compact power adapters and automotive-grade lighting drivers.
For engineers reviewing the DBLS102GH datasheet, DBLS102GH pinout, DBLS102GH application, or DBLS102GH equivalent, key selection criteria include its 100V VRRM rating, AEC-Q101 qualification, 1A continuous forward current capability, and DBLS surface-mount package compatibility with high-density PCB layouts.
Technical Context
This quad-configuration bridge rectifier integrates four silicon diodes in a single molded DBLS package with common-cathode/common-anode topology. Its thermal design supports 15°C/W junction-to-lead resistance and operates across –55°C to +150°C junction temperature range.
Electrical behavior is defined by 1.1V max VF at 1A/25°C, 2µA max IR at rated VR and 25°C, and 25pF typical junction capacitance per diode at 1MHz/4V. The device meets J-STD-020 moisture sensitivity level 1 and JESD 201 class 2 whisker resistance.
Key Specifications

| IR (max) | 2 µA - maximum reverse leakage current per diode at rated VR and 25°C, affects standby power |
| RθJL | 15 °C/W - junction-to-lead thermal resistance, enables direct heatsinking via leads in SMT layout |
| TJ max | +150 °C - maximum allowable junction temperature, sets thermal derating envelope |

IC Role / Device Role / Timing Role: Compact, surface-mount bridge replacing discrete diode solutions to reduce BOM count and board area. Use Value: DBLS package footprint (5.0 × 4.0 × 1.5 mm) saves >40% board space vs. traditional KBP or GBU packages, critical for miniaturized IoT edge devices. |
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 1A/100V rating but GBU package (larger, through-hole); no AEC-Q101 qualification | Suitable for non-automotive industrial supplies; requires PCB hole drilling and wave soldering | Select when legacy through-hole assembly is mandated and automotive qualification is unnecessary |
| DBLS102G (Taiwan Semiconductor) | Identical electrical specs and DBLS package, but lacks AEC-Q101 qualification and halogen-free labeling | Acceptable for commercial-grade lighting or adapters where automotive reliability is not required | Choose DBLS102GH over DBLS102G only when AEC-Q101 compliance or halogen-free mandate applies |
Compared with GBU2K, DBLS102GH offers superior board-area efficiency and automotive qualification but requires SMT infrastructure; versus DBLS102G, it adds AEC-Q101 validation and halogen-free assurance at identical cost and footprint-making it the preferred choice for next-gen automotive and green-electronics designs.

FAQ
What is the peak repetitive reverse voltage rating of the DBLS102GH?
The DBLS102GH has a peak repetitive reverse voltage (VRRM) rating of 100 V. This value is confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version P2103). It defines the maximum reverse voltage the device can block repeatedly without breakdown under normal operating conditions. Exceeding this rating risks irreversible avalanche failure in the DBLS102GH internal diode junctions.
Is the DBLS102GH qualified to AEC-Q101 standards?
Yes, the DBLS102GH is explicitly AEC-Q101 qualified, as indicated by the "H" suffix in its ordering code and stated in the FEATURES section of the Taiwan Semiconductor datasheet. This qualification covers stress tests including high-temperature reverse bias (HTRB), temperature cycling, and electrostatic discharge (ESD), making the DBLS102GH suitable for automotive under-hood and cabin applications where reliability is critical.
What does the "DBLS" package designation mean for the DBLS102GH?
The DBLS package for the DBLS102GH is a proprietary surface-mount, molded-plastic bridge rectifier outline measuring 5.0 × 4.0 × 1.5 mm. It features matte tin-plated leads compliant with J-STD-002 solderability and JESD 201 class 2 whisker resistance. The DBLS102GH's DBLS package enables high-density PCB layouts and eliminates through-hole mounting, distinguishing it from larger alternatives like GBU or KBP packages.
What is the maximum forward voltage drop of the DBLS102GH at rated current?
The DBLS102GH has a maximum forward voltage drop (VF) of 1.1 V per diode at IF = 1 A and TJ = 25°C, as specified in the Electrical Specifications table. This value represents worst-case conduction loss under nominal conditions and directly impacts power dissipation (P = VF × IF) and thermal design. At higher junction temperatures, VF decreases slightly, but system-level derating must account for ambient and self-heating effects on the DBLS102GH.
How does the DBLS102GH differ from the DBLS102G variant?
The DBLS102GH differs from the DBLS102G solely in qualification and material compliance: the "H" suffix denotes AEC-Q101 qualification and halogen-free construction per IEC 61249-2-21. Electrically and mechanically-including VRRM, IF, IFSM, VF, package dimensions, and pinout-the DBLS102GH and DBLS102G are identical. The DBLS102GH is the appropriate choice when automotive reliability or green-materials mandates apply.
