Product details

Overview

HDBLS104G from Taiwan Semiconductor is a 1 A, 400 V repetitive peak reverse voltage (V_RRM) quad-configuration bridge rectifier in DBLS package, featuring 1.3 V typical forward voltage at 1 A and 50 ns reverse recovery time, designed for compact, high-efficiency AC/DC conversion in space-constrained power adapters.

For engineers reviewing the HDBLS104G datasheet, HDBLS104G pinout, HDBLS104G application, or HDBLS104G equivalent, key selection criteria include its 400 V V_RRM, 50 A I_FSM, 15 °C/W junction-to-lead thermal resistance, AEC-Q101 qualification option (H-suffix), and DBLS surface-mount footprint compatibility with automated assembly.

Technical Context

HDBLS104G integrates four fast-recovery diodes in a single monolithic DBLS package with common-cathode–common-anode topology, enabling full-wave rectification without external interconnects. Its 50 ns trr and 1.3 V V_F support high-frequency switching up to 100 kHz in SMPS designs while maintaining low conduction and switching losses.

The device operates across –55 °C to +150 °C junction temperature range, with JESD201 Class 2 whisker resistance and J-STD-020 Level 1 moisture sensitivity-enabling reflow compatibility and automotive-grade reliability when ordered with 'H' suffix.

Key Specifications

V_RRM	400 V - supports input rectification for 230 VAC mains with ≥2× safety margin
I_F	1 A continuous - rated for sustained output current in sub-12 W adapter designs
I_FSM	50 A - withstands inrush surges during cold-start of LED drivers and wall adapters
V_F @ 1 A	1.3 V typical - limits conduction loss to ≤1.3 W per device at full load
t_rr	50 ns - enables efficient operation in 65–100 kHz flyback and resonant converters
R_θJL	15 °C/W - allows direct PCB copper pour heat sinking without heatsink in ≤1 W dissipation
T_J max	+150 °C - supports operation in enclosed, thermally constrained lighting and industrial enclosures

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 1 A / 400 V rating, but GBU package (larger, through-hole), 1.1 V V_F, 75 ns t_rr	Requires PCB hole drilling and wave soldering; unsuitable for fully SMT production	Select if legacy through-hole assembly or higher surge tolerance (I_FSM = 120 A) is prioritized over size and speed
MB10F (Comchip)	DBLS-equivalent footprint, 1 A / 400 V, but 1.5 V V_F, 100 ns t_rr, no AEC-Q101 option	Lacks automotive qualification and exhibits higher conduction loss at full load	Select for cost-sensitive consumer lighting where AEC-Q101 and ultra-low t_rr are not required

Compared with GBU4K and MB10F, HDBLS104G offers the optimal balance of SMT-compatible DBLS footprint, 50 ns speed, and optional AEC-Q101 qualification-making it preferred for next-gen compact, high-frequency, and automotive-adjacent power supplies.

FAQ

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

The HDBLS104G has a V_RRM of 400 V, verified per Taiwan Semiconductor's G2103 datasheet. This rating ensures safe operation with 230 VAC mains input including transient spikes and line variations. The value is laser-marked as "104" on the device body and confirmed in the Absolute Maximum Ratings table for the HDBLS104G variant specifically.

Does the HDBLS104G have AEC-Q101 qualification?

The standard HDBLS104G is not AEC-Q101 qualified; however, the AEC-Q101 version is designated HDBLS104GH and shares identical electrical parameters and DBLS package. Only the 'H' suffix indicates automotive qualification-verified in the Ordering Information section of the official datasheet.

What is the forward voltage (V_F) of the HDBLS104G at 1 A and 25 °C?

The HDBLS104G exhibits a typical 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 within the bridge and applies to each conducting half-cycle during full-wave rectification.

What is the reverse recovery time (t_rr) of the HDBLS104G?

The HDBLS104G has a reverse recovery time of 50 ns, tested at I_F = 0.5 A, I_R = 1.0 A, and I_rr = 0.25 A. This parameter is explicitly assigned to HDBLS101G–HDBLS104G variants in the datasheet's Electrical Specifications table and confirms suitability for high-frequency SMPS designs.

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

The HDBLS104G uses the DBLS package: a surface-mount, molded plastic case with matte tin-plated leads, UL 94V-0 flammability rating, J-STD-002 solderability, and JESD 201 Class 2 whisker resistance.
