Product details

Overview

HDBLS107G from Taiwan Semiconductor is a 1 A, 1000 V repetitive peak reverse voltage (V_RRM) quad-configuration bridge rectifier in DBLS package, featuring 50 A peak forward surge current (I_FSM), 1.7 V typical forward voltage at 1 A and 25°C, and 75 ns reverse recovery time - designed for high-efficiency AC/DC conversion in compact power adapters and lighting drivers.

For engineers reviewing the HDBLS107G datasheet, HDBLS107G pinout, HDBLS107G application, or HDBLS107G equivalent, key selection criteria include its 1000 V V_RRM, 15 °C/W junction-to-lead thermal resistance, AEC-Q101 qualification option (H-suffix), UL Recognized status (E-326854), and DBLS surface-mount footprint compatibility with automated assembly.

Technical Context

The HDBLS107G integrates four silicon diodes in a single-phase full-wave bridge configuration optimized for high-voltage, low-leakage operation. Its 1000 V V_RRM rating enables use in universal-input offline SMPS designs, while the 75 ns reverse recovery time supports switching frequencies up to several hundred kHz without excessive switching loss.

Thermally, the device delivers 15 °C/W junction-to-lead resistance and 40 °C/W junction-to-ambient resistance, allowing 1 A continuous forward current at ambient temperatures up to 70°C with minimal heatsinking. It meets JESD201 Class 2 whisker resistance and J-STD-020 moisture sensitivity level 1.

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)	Same 1000 V V_RRM, 1 A I_F, but GBU package (larger footprint, higher R_θJA = 50 °C/W)	Requires PCB layout revision; less suitable for space-constrained adapters	Prefer when legacy GBU footprint exists or higher surge margin (I_FSM = 150 A) is critical
MB10F (Diodes Inc.)	Lower V_RRM (1000 V same), but 1.1 V V_F typ and 50 ns t_rr; DBLS-equivalent SMB package	Better efficiency at light loads; not AEC-Q101 qualified	Prefer for cost-sensitive consumer adapters where automotive qualification is unnecessary

Compared with GBU10K and MB10F, the HDBLS107G uniquely balances ultra-compact DBLS packaging, AEC-Q101 availability, and 1000 V capability - making it optimal for next-gen space- and reliability-constrained AC/DC front-ends.

FAQ

What is the maximum repetitive peak reverse voltage (V_RRM) rating for the HDBLS107G?

The HDBLS107G has a maximum repetitive peak reverse voltage (V_RRM) rating of 1000 V. This value is explicitly specified in the Absolute Maximum Ratings table for the HDBLS107G variant and distinguishes it from lower-voltage members of the family (e.g., HDBLS101G = 50 V). The 1000 V rating enables safe operation with substantial margin across global AC mains voltages, including 277 VAC industrial systems.

Is the HDBLS107G AEC-Q101 qualified?

The base HDBLS107G is not AEC-Q101 qualified; however, the AEC-Q101-qualified version is designated HDBLS107GH (with "H" suffix). Per the Ordering Information section, the "H" denotes AEC-Q101 qualification, and this variant shares identical electrical and thermal specifications with HDBLS107G except for the added automotive reliability testing. Always verify the full part number suffix when sourcing for automotive applications.

What is the forward voltage (V_F) of the HDBLS107G at 1 A and 25°C?

The typical forward voltage (V_F) of the HDBLS107G is 1.7 V at 1 A forward current and 25°C junction temperature, as confirmed in the Electrical Specifications table under "Forward voltage per diode" for HDBLS105G through HDBLS107G. This value is measured under pulsed conditions (PW = 0.3 ms) and reflects conduction loss behavior relevant to high-frequency switching applications.

What package type does the HDBLS107G use, and what are its key mechanical attributes?

The HDBLS107G uses the DBLS surface-mount package - a compact, molded plastic case with matte tin-plated leads. Key mechanical attributes include UL 94V-0 flammability rating, J-STD-002 solderability compliance, JESD201 Class 2 whisker resistance, polarity marking on the body, and approximate weight of 0.360 g. The DBLS footprint is optimized for automated placement and offers low thermal resistance to PCB copper.

What is the reverse recovery time (t_rr) of the HDBLS107G, and how does it impact switching performance?

The reverse recovery time (t_rr) of the HDBLS107G is 75 ns, measured at I_F = 0.5 A, I_R = 1.0 A, and I_rr = 0.25 A. This parameter directly affects switching loss and EMI generation in high-frequency converters. A 75 ns t_rr enables efficient operation in flyback and buck-derived topologies switching up to ~500 kHz, reducing diode turn-off losses compared to slower general-purpose bridges.
