Taiwan Semiconductor Corporation HDBLS102G

Overview

HDBLS102G from Taiwan Semiconductor is a 1A, 100V repetitive peak reverse voltage (VRRM) quad-configuration bridge rectifier in DBLS package, featuring 50A peak forward surge current (IFSM), 15 °C/W junction-to-lead thermal resistance, and 1.0 V typical forward voltage at 1A/25°C - used in compact AC/DC front-end stages of LED drivers and low-power adapters.

For engineers reviewing the HDBLS102G datasheet, HDBLS102G pinout, HDBLS102G application, or HDBLS102G equivalent, key selection criteria include VRRM rating, IFSM capability, thermal resistance, RoHS/halogen-free compliance, and AEC-Q101 qualification status (H-suffix variant only).

Technical Context

The HDBLS102G 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 40 °C/W junction-to-ambient thermal resistance under standard PCB conditions.

Designed for high-efficiency operation, it exhibits 50 ns typical reverse recovery time (trr) at IF = 0.5A/IR = 1.0A, and maintains ≤5 µA reverse leakage per diode at 25°C and rated VR - critical for low-noise, low-loss power conversion in space-constrained designs.

Manufacturer

Taiwan Semiconductor Corporation (TSC) is a vertically integrated analog and discrete semiconductor manufacturer headquartered in Hsinchu, Taiwan, serving global industrial, computing, and consumer markets since 1979.

The HDBLS series belongs to TSC's high-efficiency bridge rectifier product line, engineered specifically for compact, thermally efficient AC/DC conversion in cost-sensitive yet reliability-critical applications such as lighting and adapters.

FAQ

What is the maximum repetitive peak reverse voltage (VRRM) of the HDBLS102G?

The HDBLS102G has a VRRM rating of 100 V, meaning each internal diode can block up to 100 V of reverse voltage repeatedly without breakdown. This value is confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version G2103), and defines the upper limit for safe AC input voltage selection in designs using the HDBLS102G.

Does the HDBLS102G have AEC-Q101 qualification?

The base HDBLS102G is not AEC-Q101 qualified; however, the variant HDBLS102GH is explicitly listed as AEC-Q101 qualified in the Ordering Information section. The "H" suffix denotes automotive-grade qualification, including stress testing for temperature cycling, humidity, and mechanical shock - essential for automotive lighting and body electronics applications.

What is the forward voltage (VF) specification for the HDBLS102G at rated current?

The HDBLS102G exhibits a typical forward voltage of 1.0 V per diode at IF = 1 A and TJ = 25°C, as specified in the Electrical Specifications table. This value increases with junction temperature and current - for example, VF rises to ~1.15 V at 125°C - and directly determines conduction losses and thermal design requirements in the HDBLS102G's application circuit.

What does the "DBLS" package designation mean for the HDBLS102G?

DBLS refers to Taiwan Semiconductor's proprietary surface-mount bridge rectifier package: a compact, molded-plastic, 4-terminal SMD outline with exposed thermal pad (not electrically active), matte tin-plated leads, and UL 94V-0 flammability rating. It is dimensionally distinct from GBU, KBU, or MBF packages and requires specific PCB pad layout per the Package Outline Dimensions drawing in the HDBLS102G datasheet.

How does the thermal performance of the HDBLS102G compare to standard bridge rectifiers?

The HDBLS102G achieves RθJL = 15 °C/W and RθJA = 40 °C/W - significantly better than many legacy bridge packages (e.g., GBU2K: RθJA ≈ 50 °C/W). This improved thermal resistance allows higher power density and longer lifetime in thermally constrained layouts, especially when mounted on 1 oz. copper with thermal vias, as validated in TSC's thermal characterization curves for the HDBLS102G.
