Product details
Overview
DBLS105GH from Taiwan Semiconductor is a 1 A, 600 V repetitive peak reverse voltage (VRRM) standard quad bridge rectifier in DBLS surface-mount package, featuring 40 A peak forward surge current (IFSM), 15 °C/W junction-to-lead thermal resistance, and AEC-Q101 qualification for automotive-grade reliability - used in AC/DC front-end stages of compact SMPS and LED drivers.
For engineers reviewing the DBLS105GH datasheet, DBLS105GH pinout, DBLS105GH application, or DBLS105GH equivalent, key selection criteria include its 600 V VRRM, 1 A average forward current rating, AEC-Q101 qualification status, DBLS package footprint compatibility, and 40 A IFSM capability under 8.3 ms half-sine surge conditions.
Technical Context
The DBLS105GH integrates four silicon diodes in a single-phase full-wave bridge configuration with common-cathode and common-anode terminals externally accessible. Its internal quad arrangement enables direct AC input rectification without external interconnection, supporting unidirectional DC output with polarity marked on the case.
Thermally optimized for surface-mount PCB use, it delivers 15 °C/W RθJL to the lead frame and 40 °C/W RθJA in still air, enabling 1 A continuous conduction at up to +125 °C ambient when properly mounted on ≥1 cm² copper pour - consistent with J-STD-020 Level 1 moisture sensitivity and UL 94V-0 mold compound compliance.

FAQ
What is the peak repetitive reverse voltage rating of the DBLS105GH?
The DBLS105GH has a repetitive peak reverse voltage (VRRM) rating of 600 V. This value is explicitly specified in the Absolute Maximum Ratings table for the DBLS105G variant in the official Taiwan Semiconductor datasheet (Version P2103). It defines the maximum instantaneous reverse voltage the device can block repeatedly without breakdown during normal operation.
Is the DBLS105GH qualified to AEC-Q101 standards?
Yes, the DBLS105GH is AEC-Q101 qualified. The "H" suffix in the part number denotes AEC-Q101 qualification, confirmed in the Ordering Information section of the Taiwan Semiconductor DBLS101G–DBLS107G datasheet. This qualification covers stress tests including temperature cycling, high-temperature reverse bias, and electrostatic discharge per automotive reliability requirements.
What is the forward voltage drop of the DBLS105GH at rated current?
The DBLS105GH has a maximum forward voltage (VF) of 1.1 V at 1 A forward current and 25 °C junction temperature. This parameter is specified in the Electrical Specifications table under "Forward voltage per diode" and reflects the total drop across two series diodes in the bridge conduction path during full-wave rectification.
What package type does the DBLS105GH use, and what are its key mechanical attributes?
The DBLS105GH uses the DBLS surface-mount package - a molded plastic case with matte tin-plated leads, UL 94V-0 flammability rating, and J-STD-002 solderability compliance. Its polarity is marked on the top surface, and it weighs approximately 0.360 g. The package outline and suggested pad layout are provided in the official Taiwan Semiconductor datasheet.
What is the peak forward surge current rating for the DBLS105GH?
The DBLS105GH has a peak forward surge current (IFSM) rating of 40 A for an 8.3 ms single half-sine wave, as specified in the Absolute Maximum Ratings table. This rating applies to the DBLS101G–DBLS105G group and ensures robustness against line-connected inrush currents in AC/DC power supplies.
