Product details
Overview
HDBL102GH from Taiwan Semiconductor is a 1A, 100V repetitive peak reverse voltage (VRRM), AEC-Q101 qualified quad bridge rectifier in DBL package, featuring glass passivated junctions, 50A peak surge current capability, and 1.0V typical forward voltage at 1A/25°C - used in automotive-grade AC-DC front-end stages of LED drivers and compact adapters.
For engineers reviewing the HDBL102GH datasheet, HDBL102GH pinout, HDBL102GH application, or HDBL102GH equivalent, key selection criteria include VRRM rating, AEC-Q101 qualification status, thermal resistance (RθJL = 15°C/W), and DBL package compatibility with high-density PCB layouts.
Technical Context
This device integrates four fast-recovery diodes in a single-phase bridge configuration with glass passivation for enhanced reliability under thermal cycling. Its 100V VRRM rating targets mid-voltage AC input applications where reverse blocking margin and low conduction loss are critical.
The HDBL102GH delivers 1.0V typical forward voltage per diode at 1A/25°C and 50ns typical reverse recovery time, enabling efficient operation in 50–100kHz SMPS designs. Junction-to-lead thermal resistance of 15°C/W supports direct heatsinking via lead frame in thermally constrained 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 1A/100V rating, but GBU package (larger footprint, higher RθJA = 50°C/W), non-AEC-Q101 | Acceptable for industrial/commercial adapters but not automotive-qualified systems | Select when cost sensitivity outweighs AEC-Q101 requirement and board space permits larger package |
| MB10F (Vishay) | 1A/100V, MB package (smaller than DBL), 1.1V VF (typ), no AEC-Q101, UL recognized | Suitable for space-limited consumer adapters; lacks automotive qualification and thermal performance | Choose for compact consumer designs where thermal margin is less critical and qualification is not required |
Compared with GBU4K and MB10F, the HDBL102GH uniquely combines AEC-Q101 qualification, DBL package density, 15°C/W RθJL, and 1.0V VF - making it the only option qualified for thermally demanding automotive LED power stages requiring both reliability and efficiency.

FAQ
What is the peak repetitive reverse voltage (VRRM) rating of the HDBL102GH?
The HDBL102GH has a VRRM rating of 100 V, meaning it can reliably block up to 100 volts of repetitive reverse voltage across its AC terminals. This rating is confirmed in the Absolute Maximum Ratings table and aligns with its position as the second variant in the HDBL101G–HDBL107G series. The HDBL102GH is designed for use with AC inputs up to approximately 70 Vrms, providing sufficient safety margin for standard low-voltage transformer outputs.
Is the HDBL102GH qualified for automotive applications?
Yes, the HDBL102GH is AEC-Q101 qualified, as indicated by the "H" suffix in its ordering code. This qualification confirms that the device has passed stress tests for temperature cycling, humidity, mechanical shock, and other conditions defined in the AEC-Q101 standard. The HDBL102GH is therefore approved for use in automotive subsystems such as LED headlamps, interior lighting controllers, and body electronics where reliability under harsh environmental conditions is mandatory.
What does the "DBL" package designation mean for the HDBL102GH?
The DBL package is a proprietary molded-plastic, surface-mountable bridge rectifier outline used exclusively by Taiwan Semiconductor. It features a compact 7.1 × 5.2 × 2.3 mm footprint with matte tin-plated leads, UL 94V-0 flammability rating, and polarity marking on the top surface. Unlike industry-standard GBU or KBU packages, DBL offers lower thermal resistance (RθJL = 15°C/W) and optimized lead geometry for improved solder joint reliability in automated assembly.
What is the typical forward voltage (VF) of the HDBL102GH at rated current?
The HDBL102GH exhibits a typical forward voltage of 1.0 V per diode at 1 A and 25°C junction temperature, as specified in the Electrical Specifications table. This value is measured under pulsed conditions (PW = 0.3 ms) and reflects low conduction loss ideal for efficiency-critical applications. At elevated temperatures (e.g., 125°C), VF decreases slightly, maintaining stable performance across its operating range.
How does the HDBL102GH differ from the HDBL102G variant?
The HDBL102GH differs from the HDBL102G solely by its AEC-Q101 qualification - the "H" suffix denotes automotive-grade testing and screening. Both share identical electrical parameters (VRRM = 100 V, IF = 1 A, VF = 1.0 V), thermal characteristics (RθJL = 15°C/W), and DBL package dimensions. The HDBL102GH undergoes additional qualification testing per AEC-Q101, including accelerated life testing and failure analysis, making it suitable for automotive applications where the standard HDBL102G is not permitted.
