Product details
Overview
HDBLS105GH from Taiwan Semiconductor is a 1A, 600V repetitive peak reverse voltage (VRRM) AEC-Q101-qualified quad bridge rectifier in DBLS package, featuring 1.7V max forward voltage at 1A and 75ns reverse recovery time, used in automotive-grade AC/DC front-end conversion for lighting and adapters.
For engineers reviewing the HDBLS105GH datasheet, HDBLS105GH pinout, HDBLS105GH application, or HDBLS105GH equivalent, key selection criteria include VRRM = 600V, IF = 1A, AEC-Q101 qualification, trr = 75ns, and DBLS surface-mount package compatibility with high-surge SMPS designs.
Technical Context
This device integrates four fast-recovery diodes in a single DBLS molded plastic package configured as a full-wave bridge, enabling compact AC input rectification without external interconnects. Its 75ns reverse recovery time and 1.7V forward voltage support efficient operation in 50–400kHz switching power supplies.
The HDBLS105GH meets JESD201 Class 2 whisker resistance and UL 94V-0 flammability standards, with matte tin-plated leads solderable per J-STD-002 and moisture sensitivity level 1 - confirming suitability for lead-free reflow assembly in automotive and industrial production.

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) | VRRM = 800V, IF = 6A, trr = 250ns, GBU package (larger, through-hole) | Higher current rating but slower recovery; requires PCB hole drilling and larger layout area | Select when higher surge tolerance (IFSM = 200A) outweighs size and speed constraints |
| DF08MA (Vishay) | VRRM = 800V, IF = 0.8A, trr = 150ns, DO-214AA package (discrete dual) | Lower current, discrete implementation requiring two devices and extra traces for bridge formation | Choose only if DBLS footprint is unavailable and design allows manual bridge assembly |
Compared with GBU6K and DF08MA, the HDBLS105GH offers optimal balance of AEC-Q101 compliance, 600V/1A rating, 75ns speed, and compact DBLS SMT integration - making it preferred for space- and reliability-critical automotive and commercial lighting designs where lead count, thermal performance, and qualification status are decisive.

FAQ
What is the peak repetitive reverse voltage rating of the HDBLS105GH?
The HDBLS105GH has a repetitive peak reverse voltage (VRRM) rating of 600 V. This value is confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version G2103), and defines the maximum instantaneous reverse voltage the device can block repeatedly without breakdown under normal operating conditions.
Is the HDBLS105GH qualified to AEC-Q101 standards?
Yes, the HDBLS105GH is explicitly AEC-Q101 qualified, as indicated by the "H" suffix in its ordering code and confirmed in the FEATURES section of the datasheet. This qualification covers stress tests including high-temperature operating life, temperature cycling, and unbiased highly accelerated stress testing - validating its suitability for automotive electronic systems.
What is the forward voltage drop of the HDBLS105GH at 1A and 25°C?
The HDBLS105GH exhibits a maximum forward voltage (VF) of 1.7 V at IF = 1 A and TJ = 25°C, per the Electrical Specifications table. This value applies to each diode within the bridge and directly impacts conduction loss and thermal design in the target application.
What does the "DBLS" package designation mean for the HDBLS105GH?
The DBLS package is Taiwan Semiconductor's proprietary 4-terminal surface-mount molded plastic case for bridge rectifiers. It features gull-wing leads, UL 94V-0 flammability rating, matte tin plating compliant with J-STD-002, and a polarity marking on the top surface - all documented in the Mechanical Data and Package Outline sections for the HDBLS105GH.
What is the reverse recovery time specification for the HDBLS105GH?
The HDBLS105GH has a typical reverse recovery time (trr) of 75 ns, measured at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This parameter is specified in the Electrical Specifications table and distinguishes the HDBLS105GH from lower-voltage variants (e.g., HDBLS104G at 50 ns) due to optimized carrier lifetime for 600V blocking capability.
