Product details
Overview
HDBLS103GH from Taiwan Semiconductor is a 1A, 200V repetitive peak reverse voltage (VRRM) AEC-Q101-qualified quad bridge rectifier in DBLS package, featuring 1.0V 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 HDBLS103GH datasheet, HDBLS103GH pinout, HDBLS103GH application, or HDBLS103GH equivalent, key selection criteria include VRRM=200V, IFSM=50A, TJ(max)=150°C, RθJL=15°C/W, and AEC-Q101 qualification for under-hood automotive use.
Technical Context
This device integrates four fast-recovery diodes in a single DBLS surface-mount package to form a full-wave bridge configuration. It delivers 1A average forward current with low conduction loss (VF ≤1.0V @1A, 25°C) and fast switching (trr ≤50ns), enabling high-efficiency AC/DC conversion in compact layouts.
Thermally optimized with RθJL = 15°C/W and RθJA = 40°C/W, the HDBLS103GH supports operation from –55°C to +150°C junction temperature and withstands 50A non-repetitive surge current (8.3ms half-sine), meeting stringent automotive reliability requirements per AEC-Q101.

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/200V rating but GBU package (larger, through-hole); trr = 75ns; no AEC-Q101 | Designed for general-purpose industrial adapters, not automotive environments | Select when cost-sensitive, non-automotive, or through-hole assembly is required |
| MB10F (Vishay) | 1A/1000V rating; slower trr = 150ns; TO-220AC package; no AEC-Q101 | Targeted at high-voltage universal-input SMPS where VRRM margin >200V is critical | Select only if higher reverse voltage rating is mandatory and AEC-Q101 is not required |
Compared with GBU4K and MB10F, the HDBLS103GH uniquely combines AEC-Q101 qualification, DBLS surface-mount packaging, 50ns trr, and 200V VRRM-making it the only option qualified for thermally demanding, space-constrained automotive rectification where reliability and footprint matter.

FAQ
What is the peak repetitive reverse voltage rating of the HDBLS103GH?
The HDBLS103GH has a repetitive peak reverse voltage (VRRM) rating of 200 V. This value is specified in the Absolute Maximum Ratings table and confirmed across all electrical test conditions in the datasheet. The HDBLS103GH is designed to reliably block up to 200 V in reverse bias without breakdown under normal operating conditions and thermal limits.
Is the HDBLS103GH qualified for automotive applications?
Yes, the HDBLS103GH is AEC-Q101 qualified, as explicitly stated in the FEATURES section and ORDERING INFORMATION notes ("H" suffix denotes AEC-Q101 qualification). This qualification covers stress testing for temperature cycling, humidity, mechanical shock, and other automotive-specific reliability requirements, making the HDBLS103GH suitable for under-hood and cabin electronics.
What is the forward voltage drop of the HDBLS103GH at rated current?
The HDBLS103GH exhibits a maximum forward voltage (VF) of 1.0 V at IF = 1 A and TJ = 25°C, per the Electrical Specifications table. This value applies to each diode within the bridge and reflects typical conduction loss under standard test conditions using a 0.3 ms pulse width.
Does the HDBLS103GH have a defined reverse recovery time?
Yes, the HDBLS103GH has a specified reverse recovery time (trr) of ≤50 ns under test conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This parameter is documented in the Electrical Specifications table and applies to HDBLS101G–HDBLS104G variants, confirming fast-switching behavior critical for high-frequency SMPS designs.
What package type does the HDBLS103GH use, and what are its key mechanical attributes?
The HDBLS103GH uses the DBLS surface-mount package: a molded plastic case rated UL 94V-0, with matte tin-plated leads compliant with J-STD-002 solderability and JESD 201 Class 2 whisker resistance. Its weight is approximately 0.360 g, and polarity is marked on the top surface per the Marking Diagram.
