Product details
Overview
HDBLS104GH from Taiwan Semiconductor is a 1A, 400V repetitive peak reverse voltage (VRRM) AEC-Q101-qualified quad bridge rectifier in DBLS package, featuring 1.3V max forward voltage at 1A and 50ns reverse recovery time, used in automotive-grade switching mode power supplies and lighting adapters.
For engineers reviewing the HDBLS104GH datasheet, HDBLS104GH pinout, HDBLS104GH application, or HDBLS104GH equivalent, key selection criteria include VRRM=400V, IFSM=50A surge rating, TJ(max)=150°C, AEC-Q101 qualification, and DBLS surface-mount package compatibility with high-density PCB layouts.
Technical Context
This device integrates four diodes in a single-phase full-wave bridge configuration, enabling AC-to-DC conversion without external interconnects. Its 15°C/W junction-to-lead thermal resistance and 40°C/W junction-to-ambient rating support reliable operation under sustained 1A average forward current at elevated ambient temperatures.
The HDBLS104GH delivers fast switching performance with trr ≤50ns and low leakage (IR ≤5µA at 25°C), making it suitable for high-frequency SMPS designs where efficiency and thermal management are critical. It meets JESD201 Class 2 whisker resistance and UL 94V-0 flammability requirements.

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) | VRRM=400V, IF=4A, trr=75ns, larger GBU package (10.5×14.5mm vs DBLS 7.1×5.2mm) | Higher current rating but 2.5× larger footprint; not AEC-Q101 qualified | Select when higher IF margin is needed and board space permits; avoid for automotive AEC-Q101 compliance |
| MB10F (Vishay) | VRRM=400V, IF=1A, trr=150ns, MB-10 package (10×8.5mm), no AEC-Q101 qualification | Slower recovery increases switching loss above 50kHz; lacks automotive qualification and moisture level 1 rating | Acceptable for cost-sensitive industrial adapters without automotive or high-frequency requirements |
Compared with GBU4K and MB10F, the HDBLS104GH offers superior space efficiency (DBLS footprint), faster switching (50ns trr), and automotive-grade reliability (AEC-Q101 + MSL1), making it optimal for compact, thermally demanding, and automotive-qualified designs where 1A average current suffices.

FAQ
What is the peak repetitive reverse voltage rating for HDBLS104GH?
The HDBLS104GH has a repetitive peak reverse voltage (VRRM) rating of 400 V. This value is confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version G2103), where HDBLS104G is explicitly listed with VRRM = 400 V. This rating defines the maximum AC voltage the device can block in reverse bias without breakdown during normal operation.
Is HDBLS104GH qualified to AEC-Q101 standards?
Yes, the "H" suffix in HDBLS104GH denotes AEC-Q101 qualification. The datasheet states "AEC-Q101 qualified available" for the HDBLS101G–HDBLS107G series, and the ordering information explicitly defines "H" as indicating AEC-Q101 qualification. This makes HDBLS104GH suitable for automotive applications requiring stress-tested reliability under temperature cycling, humidity, and mechanical shock.
What is the forward voltage drop of HDBLS104GH at rated current?
The HDBLS104GH exhibits a maximum forward voltage (VF) of 1.3 V per diode at IF = 1 A and TJ = 25°C, as specified in the Electrical Specifications table. This value is distinct from lower-voltage variants (e.g., HDBLS101G–HDBLS103G: VF ≤1.0 V) and higher-voltage variants (HDBLS105G–HDBLS107G: VF ≤1.7 V), reflecting optimized doping for its 400V VRRM rating.
What package type does HDBLS104GH use, and what are its key mechanical properties?
HDBLS104GH uses the DBLS surface-mount package: dimensions 7.1 × 5.2 × 2.3 mm, matte tin-plated leads, UL 94V-0 molding compound, and polarity marking on top. Its 0.360 g mass and JESD201 Class 2 whisker resistance support automated assembly and long-term reliability in vibration-prone environments such as automotive and industrial installations.
Does HDBLS104GH have moisture sensitivity level (MSL) rating, and what does it mean for assembly?
Yes, HDBLS104GH has Moisture Sensitivity Level 1 (MSL1) per J-STD-020. This means the device has no floor life limitation and requires no baking prior to reflow soldering. It can be stored indefinitely at ≤30°C/60% RH and placed directly into standard lead-free reflow profiles without moisture-induced popcorning risk - simplifying manufacturing for high-mix, low-volume production lines.
