Product details
Overview
HDBLS101GH from Taiwan Semiconductor is a 1 A, 50 V repetitive peak reverse voltage (VRRM) high-efficiency bridge rectifier in DBLS package, featuring quad configuration, 50 A peak forward surge current (IFSM), and 150 °C maximum junction temperature - used in compact AC/DC adapters and lighting power supplies.
For engineers reviewing the HDBLS101GH datasheet, HDBLS101GH pinout, HDBLS101GH application, or HDBLS101GH equivalent, key selection criteria include its AEC-Q101 qualification, 1.0 V typical forward voltage at 1 A, 5 µA max reverse leakage at 25 °C, and UL Recognized status (E-326854) for safety-critical board-level integration.
Technical Context
This device integrates four silicon diodes in a single-phase full-wave bridge configuration with common-cathode and common-anode terminals, enabling direct AC-to-DC conversion without external interconnects. Its DBLS surface-mount package supports automated assembly and delivers 15 °C/W junction-to-lead thermal resistance for reliable conduction under continuous 1 A load.
The HDBLS101GH operates across –55 °C to +150 °C junction temperature range and meets J-STD-020 moisture sensitivity level 1, making it suitable for reflow-soldered industrial and automotive-grade power stages where thermal cycling and long-term reliability are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 50 V - Maximum non-repetitive reverse voltage the bridge withstands without breakdown; defines minimum input AC peak rating (e.g., ≤35 V RMS). |
| IF | 1 A - Continuous average forward output current per bridge; determines usable DC load capacity in SMPS secondary side. |
| IFSM | 50 A - Single half-sine surge current capability (8.3 ms); enables robustness against line transients and inrush in adapter inputs. |
| VF (per diode) | 1.0 V typ @ 1 A, 25 °C - Total forward drop across two series diodes = ~2.0 V; directly impacts conduction loss and thermal design. |
| RθJL | 15 °C/W - Junction-to-lead thermal resistance; allows accurate PCB copper pour sizing for heatsinking when lead is soldered to thermal pad. |
| TJ max | +150 °C - Maximum allowable junction temperature; sets upper limit for ambient + power dissipation margin in enclosed lighting fixtures. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU4A (ON Semiconductor) | Same 1 A / 50 V rating, but GBU package (larger, through-hole); 1.1 V VF max; no AEC-Q101 or UL recognition. | Requires PCB hole drilling and wave soldering; unsuitable for automated SMT lines or automotive qualification. | Select only if legacy through-hole assembly is mandated and AEC-Q101/UL are not required. |
| MB1S (Vishay) | SMD MB-1 package; 1 A / 50 V; 1.05 V VF max; RoHS/halogen-free; no AEC-Q101 or UL file. | Lacks automotive qualification and safety certification - limited to consumer-grade lighting or non-safety-critical adapters. | Choose when cost is primary constraint and safety certifications are waived by end-equipment standards. |
Compared with GBU4A and MB1S, the HDBLS101GH uniquely combines AEC-Q101 qualification, UL Recognition, and DBLS SMT packaging - delivering certified reliability and manufacturability in one component for automotive-adjacent and safety-regulated power designs.

FAQ
What is the peak reverse voltage rating of the HDBLS101GH?
The HDBLS101GH has a repetitive peak reverse voltage (VRRM) rating of 50 V. This means it can safely block up to 50 V of reverse voltage across its AC terminals without breakdown. It is designed for use with AC input voltages whose peak value does not exceed this rating - for example, ≤35 V RMS sine-wave inputs. Exceeding VRRM risks irreversible avalanche failure of the internal diodes.
Is the HDBLS101GH qualified for automotive applications?
Yes, the HDBLS101GH is AEC-Q101 qualified. The "H" suffix in the part number explicitly denotes qualification to the AEC-Q101 stress test standard for discrete semiconductors, covering tests such as temperature cycling, high-temperature storage life, and biased humidity testing. This makes the HDBLS101GH suitable for automotive interior lighting, body control modules, and other under-hood–adjacent applications where reliability under thermal and environmental stress is mandatory.
What is the forward voltage drop of the HDBLS101GH at rated current?
The HDBLS101GH exhibits a typical forward voltage (VF) of 1.0 V per diode at IF = 1 A and TJ = 25 °C. Since a full-wave bridge conducts through two diodes in series during each half-cycle, the total forward drop is approximately 2.0 V under those conditions. This value increases with junction temperature and current, directly affecting conduction losses and thermal design margins in the final application.
Does the HDBLS101GH have UL safety certification?
Yes, the HDBLS101GH is UL Recognized under File # E-326854. This recognition confirms compliance with UL 60950-1 and UL 62368-1 standards for insulation, flammability (UL 94V-0), and construction integrity. UL Recognition simplifies end-product safety certification by eliminating the need for additional component-level evaluation in many Class II power supply designs.
What package type and mounting method does the HDBLS101GH use?
The HDBLS101GH uses the DBLS surface-mount package - a compact, molded plastic case with four coplanar matte tin-plated leads. It is designed for reflow soldering onto PCBs using standard JEDEC-compliant profiles. The package features polarity marking on the top surface and meets J-STD-002 for solderability and JESD 201 Class 2 for whisker resistance, ensuring robust automated assembly yield.
