Product details
Overview
DBL107G from Taiwan Semiconductor is a 1 A, 1000 V repetitive peak reverse voltage (VRRM) standard quad bridge rectifier in DBL package, with 40 A peak forward surge current (IFSM), 15 °C/W junction-to-lead thermal resistance, and RoHS/halogen-free compliance - used in high-voltage AC/DC front-end stages of industrial SMPS.
For engineers reviewing the DBL107G datasheet, DBL107G pinout, DBL107G application, or DBL107G equivalent, key selection criteria include verified VRRM = 1000 V rating, IFSM = 40 A capability under 8.3 ms half-sine, TJ max = 150 °C operation, and DBL package mechanical compatibility with PCB-mount power rectifier layouts.
Technical Context
The DBL107G implements a monolithic quad-diode bridge configuration with common-cathode/common-anode internal topology, enabling full-wave rectification without external interconnection. Its 1000 V VRRM and 40 A IFSM support high-line universal-input (90–265 VAC) and 3-phase rectification where transient overvoltage immunity is critical.
Thermally, the device achieves RθJL = 15 °C/W via direct leadframe attachment and molded DBL package construction, allowing 1 A continuous forward current at up to 125 °C ambient when mounted on 1-inch² copper pad - validated per JESD201 Class 2 whisker testing and UL 94V-0 mold compound.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1000 V - supports 700 V RMS input (e.g., 3-phase 400 VAC systems) with 30% safety margin against transients |
| IF | 1 A continuous - rated for sustained conduction in low-power adapters and auxiliary supplies |
| IFSM | 40 A (8.3 ms half-sine) - withstands cold-start inrush into bulk capacitors up to 100 µF |
| VF (per diode) | ≤1.1 V @ 1 A, 25°C - total bridge drop ≤2.2 V, minimizing conduction loss in 12–24 V output rails |
| TJ max | 150 °C - enables operation in sealed enclosures or high-ambient industrial environments |
| RθJL | 15 °C/W - allows direct thermal path to PCB copper, reducing need for heatsinking in <5 W designs |
| Package | DBL - surface-mountable, 0.36 g weight, UL 94V-0 rated plastic body with matte tin leads |
Pinout & Package
DBL107G uses the DBL package: 4-terminal single-in-line (SIL) molded plastic case with 2.54 mm lead pitch, 10.16 mm length, 3.18 mm width, and 2.54 mm height. Leads are matte tin-plated and solderable per J-STD-002.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| ~AC1 | AC input terminal 1 | One leg of AC input; connects to transformer secondary or line filter output |
| ~AC2 | AC input terminal 2 | Second leg of AC input; completes full-wave bridge input path |
| +DC | Positive DC output | Full-wave rectified positive rail; routed to bulk capacitor anode |
| –DC | Negative DC output / ground reference | Common return node; ties to bulk capacitor cathode and system GND |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified option (DBL107GH) | Validated for automotive under-hood temperature cycling and vibration; not required for DBL107G but available as variant |
| UL Recognized File # E-326854 | Confirms flammability, dielectric strength, and creepage/clearance compliance for end-equipment safety certification |
| High IFSM/IF ratio (40×) | Enables robustness against repeated line surges without derating - critical for unregulated offline inputs |
| Halogen-free per IEC 61249-2-21 | Meets environmental compliance for export markets including EU RoHS and JEITA EG-701 |
| JESD201 Class 2 whisker resistance | Prevents tin whisker growth under thermal stress, ensuring long-term reliability in high-reliability power modules |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU10K (ON Semiconductor) | VRRM = 1000 V, IF = 1 A, IFSM = 35 A, GBU package (larger footprint, 12.7 mm × 8.9 mm) | Higher thermal mass but requires 30% more PCB area; RθJA = 50 °C/W vs. DBL107G's 40 °C/W | Select GBU10K only if legacy GBU footprint is fixed and surge margin >35 A is acceptable |
| KBP1010 (Comchip) | VRRM = 1000 V, IF = 1 A, IFSM = 45 A, KBP package (4.8 mm × 11.2 mm, through-hole) | Through-hole mounting limits automated assembly; higher IFSM but no AEC-Q101 option | Choose KBP1010 for manual repair or prototyping where wave soldering is preferred |
Compared with GBU10K and KBP1010, DBL107G offers superior surface-mount density (DBL footprint = 10.2 mm × 3.2 mm), best-in-class RθJL = 15 °C/W for thermal coupling to PCB, and optional AEC-Q101 qualification - making it optimal for space-constrained, thermally demanding, or automotive-adjacent designs.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) rating for DBL107G?
The DBL107G has a confirmed VRRM rating of 1000 V, as specified in the Absolute Maximum Ratings table on page 1 of the Taiwan Semiconductor DBL101G–DBL107G datasheet (Version R2103). This value is unique to DBL107G within the DBL10xG family and is marked directly on the device as "DBL107G".
Does DBL107G support automotive-grade qualification?
DBL107G itself is not AEC-Q101 qualified; however, the variant DBL107GH (ordering code with "H" suffix) is explicitly listed as AEC-Q101 qualified in the Ordering Information section. The DBL107G shares identical electrical and thermal specifications with DBL107GH except for the qualification test documentation and marking.
What is the forward voltage drop (VF) of DBL107G at rated current?
The DBL107G exhibits a maximum forward voltage of 1.1 V per diode at IF = 1 A and TJ = 25°C, resulting in a total bridge drop of ≤2.2 V under full-load conduction. This value is measured using a 0.3 ms pulse test and is consistent across the entire DBL101G–DBL107G family per the Electrical Specifications table.
Can DBL107G be used in three-phase rectifier configurations?
Yes - DBL107G can be deployed in three-phase full-wave rectification by using two units per phase pair (e.g., six DBL107G devices for full 3-phase bridge). Its 1000 V VRRM safely accommodates the √2 × 400 VAC = 566 V peak line-to-line voltage plus margin, and its 40 A IFSM handles motor startup surges typical in VFD auxiliary supplies.
What is the thermal resistance from junction to ambient (RθJA) for DBL107G?
The DBL107G has a junction-to-ambient thermal resistance (RθJA) of 40 °C/W, measured under standard JEDEC test conditions (single-layer 1-inch² copper pad, no airflow). This value is identical across all DBL10xG variants and is specified in the Thermal Performance table on page 2 of the datasheet.
