Product details

Overview

HDBLS104G from Taiwan Semiconductor is a 1A, 400V repetitive peak reverse voltage (V_RRM) quad-configuration bridge rectifier in DBLS package, featuring 1.3V max forward voltage at 1A/25°C, 50ns reverse recovery time, and AEC-Q101 qualification option - used in compact AC/DC front-end stages of LED drivers and industrial adapters.

For engineers reviewing the HDBLS104G datasheet, HDBLS104G pinout, HDBLS104G application, or HDBLS104G equivalent, key selection criteria include V_RRM = 400V, I_F = 1A, t_rr = 50ns, R_θJA = 40°C/W, and DBLS surface-mount compatibility with JEDEC-standard PCB layout.

Technical Context

The HDBLS104G integrates four fast-recovery diodes in a single-phase full-wave bridge configuration, optimized for high-efficiency switching-mode power conversion where low conduction loss and rapid turn-off are critical. Its 50ns reverse recovery time and 1.3V forward voltage directly support high-frequency operation up to 100 kHz in offline SMPS designs.

Thermally, the DBLS package delivers R_θJL = 15°C/W and R_θJA = 40°C/W, enabling 1A continuous operation without forced air at ambient temperatures ≤70°C. The device meets J-STD-020 moisture sensitivity level 1 and UL 94V-0 flammability requirements.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	400 V - supports 280 V_RMS AC input with 1.4× safety margin for universal-line SMPS
I_F	1 A continuous - rated for sustained output current in 5–15 W adapter and lighting applications
t_rr	50 ns - enables efficient operation at ≥50 kHz switching frequencies with minimal switching loss
V_F (max)	1.3 V @ 1 A, 25°C - reduces conduction loss to ≤1.3 W per bridge in full-wave rectification
R_θJA	40 °C/W - allows thermal design with standard 2-layer PCB copper area (≥1 cm²) without heatsink
I_FSM	50 A (8.3 ms) - withstands cold-start surge in capacitive-input rectifier circuits
Junction temp	−55°C to +150°C - supports operation in automotive under-hood and industrial ambient environments

Equivalent & Alternatives

The following parts are listed as comparable options for similar bridge rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
GBU4K (ON Semiconductor)	Same DBLS footprint, but 1.1 V V_F (lower), 600 V V_RRM, 75 ns t_rr	Better conduction loss at low T_J; slower recovery limits >60 kHz use	Select when lower V_F dominates over speed; verify layout compatibility with GBU4K's slightly larger lead pitch
MB10F (Diodes Inc.)	Smaller MBF package, 1 A/1000 V, 1.1 V V_F, 500 ns t_rr	Higher V_RRM but significantly slower - unsuitable for high-frequency SMPS	Choose only for cost-sensitive, low-frequency (<20 kHz), high-voltage margin applications where space is constrained

Compared with GBU4K and MB10F, the HDBLS104G uniquely balances 400 V rating, 50 ns speed, and 1.3 V V_F in the DBLS package - making it optimal for space-constrained, medium-frequency LED drivers and adapters where thermal and EMI performance are prioritized.

FAQ

What is the maximum repetitive peak reverse voltage (V_RRM) of the HDBLS104G?

The HDBLS104G has a V_RRM of 400 V, confirmed in the Absolute Maximum Ratings table across all versions of the HDBLS101G–HDBLS107G datasheet. This rating defines the highest instantaneous reverse voltage the device can block repeatedly without breakdown, supporting 280 V_RMS AC inputs with standard safety margin. The HDBLS104G is part of a voltage-scaled family where '104' encodes 400 V.

Does the HDBLS104G have AEC-Q101 qualification?

The base HDBLS104G is not AEC-Q101 qualified, but the variant HDBLS104GH - indicated by the 'H' suffix in the ordering code - is explicitly AEC-Q101 qualified per the Ordering Information section. This qualification covers temperature cycling, mechanical shock, and humidity testing required for automotive power electronics. Always specify HDBLS104GH for automotive-grade applications.

What is the forward voltage (V_F) specification for the HDBLS104G at rated current?

The HDBLS104G has a maximum forward voltage of 1.3 V at I_F = 1 A and T_J = 25°C, as specified in the Electrical Specifications table. This value is measured per diode under pulse conditions (PW = 0.3 ms), and represents worst-case conduction loss across the bridge's two conducting diodes in series during each half-cycle.

What is the reverse recovery time (t_rr) of the HDBLS104G, and how is it tested?

The HDBLS104G has a typical reverse recovery time of 50 ns, measured under conditions of I_F = 0.5 A, I_R = 1.0 A, and I_rr = 0.25 A, as stated in the Electrical Specifications table. This parameter reflects the diode's ability to switch off rapidly, directly impacting switching loss and EMI in high-frequency SMPS designs where the HDBLS104G is commonly deployed.

What package type does the HDBLS104G use, and what are its key mechanical attributes?

The HDBLS104G uses the DBLS surface-mount package - a molded plastic case with matte tin-plated leads, UL 94V-0 flammability rating, and polarity marking on top. It weighs approximately 0.360 g and complies with JESD 201 Class 2 whisker resistance and J-STD-020 Level 1 moisture sensitivity, enabling standard reflow assembly without baking.
