Product details
Overview
HDBLS102GH from Taiwan Semiconductor is a 1A, 100V AEC-Q101-qualified high-efficiency bridge rectifier in DBLS package, featuring 50A peak surge current, 15 °C/W junction-to-lead thermal resistance, and 1.0 V typical forward voltage at 1A/25°C - used in automotive-grade AC/DC adapters and lighting power supplies.
For engineers reviewing the HDBLS102GH datasheet, HDBLS102GH pinout, HDBLS102GH application, or HDBLS102GH equivalent, key selection criteria include repetitive peak reverse voltage (100 V), AEC-Q101 qualification status, moisture sensitivity level (MSL 1), UL recognition (E-326854), and quad configuration suitability for compact PCB layouts.
Technical Context
This device integrates four silicon diodes in a single-phase full-wave bridge configuration with common-cathode/common-anode topology. It supports 1 A average forward current at 150 °C junction temperature and delivers 50 A non-repetitive surge capability per 8.3 ms half-sine waveform.
Thermal performance is defined by RθJL = 15 °C/W and RθJA = 40 °C/W, enabling reliable operation in thermally constrained environments. Reverse recovery time is 50 ns at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A.

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU2K | Same 1A/100V rating but TO-220AC package; higher RθJA (50 °C/W); no AEC-Q101 or UL recognition | Requires heatsinking in >0.5 A continuous loads; not suitable for automotive or safety-certified end equipment | Select GBU2K only for cost-sensitive, non-automotive, non-UL applications where board space allows through-hole mounting |
| GBU2J | 1A/600V rating; same DBLS package; VF = 1.1 V (typ); no AEC-Q101 qualification | Higher VRRM enables use in universal-input (85–265 VAC) SMPS; lacks automotive reliability validation | Choose GBU2J when higher reverse voltage margin is needed and AEC-Q101 is not required |
Compared with HDBLS102GH, GBU2K offers lower cost but requires mechanical mounting and lacks automotive/safety certifications, while GBU2J trades 100 V rating for 600 V capability and omits AEC-Q101 - making HDBLS102GH the sole choice for space-constrained, automotive-qualified 100 V bridge applications.

FAQ
What is the peak repetitive reverse voltage rating of the HDBLS102GH?
The HDBLS102GH has a repetitive peak reverse voltage (VRRM) rating of 100 V. This value is confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version G2103). Exceeding this voltage may cause irreversible breakdown. The HDBLS102GH is part of a family spanning 50 V to 1000 V, with each variant marked distinctly - HDBLS102GH specifically denotes the 100 V version.
Is the HDBLS102GH qualified to AEC-Q101 standards?
Yes, the "H" suffix in HDBLS102GH explicitly indicates AEC-Q101 qualification, as documented in the Ordering Information section of the datasheet. This includes testing for temperature cycling, high-temperature storage life, and biased highly accelerated stress testing. The HDBLS102GH is validated for automotive under-hood and interior applications where reliability under thermal and mechanical stress is critical.
What is the forward voltage drop of the HDBLS102GH at rated current?
The HDBLS102GH exhibits a typical forward voltage (VF) of 1.0 V per diode at IF = 1 A and TJ = 25°C, as specified in the Electrical Specifications table. This value is measured under pulsed conditions (PW = 0.3 ms) and reflects conduction loss in full-wave rectification. At elevated junction temperatures, VF decreases slightly due to negative temperature coefficient behavior of silicon diodes.
Does the HDBLS102GH require moisture sensitivity handling before reflow soldering?
No, the HDBLS102GH is rated MSL 1 per J-STD-020, meaning it has unlimited floor life and does not require dry pack storage or baking prior to reflow. This simplifies manufacturing logistics and eliminates preconditioning steps in SMT lines. The MSL 1 classification is verified in the Mechanical Data section and applies to the DBLS package's molded compound and lead finish.
What is the thermal resistance from junction to ambient for the HDBLS102GH?
The HDBLS102GH has a junction-to-ambient thermal resistance (RθJA) of 40 °C/W under standard JEDEC test conditions (single-layer 1 in² copper pad). This value assumes no external heatsinking and is used to estimate steady-state junction temperature rise above ambient. For higher-power designs, RθJL = 15 °C/W provides a more accurate path when leads are connected to internal copper planes.
