Product details

Overview

HDBLS101G from Taiwan Semiconductor is a 1 A, 50 V repetitive peak reverse voltage (V_RRM) quad-configuration bridge rectifier in DBLS package, featuring 1.0 V typical forward voltage at 1 A and 50 ns reverse recovery time, designed for compact, high-efficiency AC/DC conversion in space-constrained power adapters.

For engineers reviewing the HDBLS101G datasheet, HDBLS101G pinout, HDBLS101G application, or HDBLS101G equivalent, key selection criteria include its 50 V V_RRM, 50 A I_FSM, 15 °C/W junction-to-lead thermal resistance, AEC-Q101 qualification availability (H-suffix variant), and UL recognition per File #E-326854.

Technical Context

The HDBLS101G integrates four silicon diodes in a single-phase full-wave bridge configuration with common-cathode and common-anode terminals, enabling direct AC input to DC output rectification without external interconnection. Its 50 V V_RRM rating targets low-voltage offline and auxiliary power supply designs where surge immunity and thermal efficiency are critical.

Thermal performance is defined by R_θJL = 15 °C/W and R_θJA = 40 °C/W, supporting 1 A continuous operation up to +125 °C ambient when mounted on standard PCB copper. The device meets JESD201 Class 2 whisker resistance and J-STD-020 moisture sensitivity Level 1.

Key Specifications

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)	4 A rating, 400 V V_RRM, GBPC package (larger footprint), 1.1 V V_F, 250 ns t_rr	Higher voltage/current capacity; suited for 120 V AC primary-side rectification, not optimized for low-V_RRM adapter secondaries.	Select when higher surge margin or legacy through-hole compatibility is required; not drop-in due to package and pinout mismatch.
MB1S (Vishay)	1 A, 50 V, SMB package, 1.1 V V_F, 75 ns t_rr, no UL recognition or AEC-Q101 option	Smaller footprint but lower thermal performance (R_θJA ≈ 65 °C/W); lacks safety certification for regulated end equipment.	Consider for cost-sensitive, non-certified consumer products where board space is constrained and thermal headroom exists.

Compared with GBU4A and MB1S, the HDBLS101G offers best-in-class thermal resistance (15 °C/W), UL recognition, and AEC-Q101 availability in a compact DBLS package-making it optimal for certified, space-limited, low-voltage adapter and auxiliary supply designs.

FAQ

What is the maximum repetitive peak reverse voltage (V_RRM) of the HDBLS101G?

The HDBLS101G has a V_RRM of 50 V, meaning it can reliably block up to 50 V of reverse voltage across its output terminals during each AC cycle. This rating is confirmed in the Absolute Maximum Ratings table and applies specifically to the HDBLS101G variant-not the broader HDBLS101G–HDBLS107G family. Exceeding this voltage risks irreversible breakdown.

Does the HDBLS101G have AEC-Q101 qualification?

The HDBLS101G itself is not AEC-Q101 qualified; however, the AEC-Q101 version is designated HDBLS101GH (with 'H' suffix). Per the Ordering Information section, only variants ending in 'H' meet AEC-Q101 stress test requirements for automotive applications. Standard HDBLS101G is rated for industrial and consumer use.

What is the forward voltage (V_F) of the HDBLS101G at 1 A and 25 °C?

The HDBLS101G exhibits a typical forward voltage of 1.0 V per diode at I_F = 1 A and T_J = 25 °C, as specified in the Electrical Specifications table. This value is measured under pulsed conditions (PW = 0.3 ms) and represents conduction loss in one diode leg of the bridge-total bridge drop is effectively 2 × V_F in full-wave operation.

What does the 'G' suffix in HDBLS101G indicate?

The 'G' suffix in HDBLS101G denotes green (halogen-free) molding compound compliant with IEC 61249-2-21, as stated in the Features section. It is distinct from the 'H' suffix used for AEC-Q101 qualification. All HDBLS101G–HDBLS107G variants carry the 'G' suffix to indicate halogen-free construction.

Is the HDBLS101G UL recognized, and what is its file number?

Yes, the HDBLS101G is UL Recognized with File #E-326854, as explicitly listed in the FEATURES section. This recognition covers the entire HDBLS101G–HDBLS107G series and confirms compliance with UL 60950-1 and UL 62368-1 for use in end-product safety certification.
