Product details

Overview

HDBLS105G from Taiwan Semiconductor is a 1 A, 600 V repetitive peak reverse voltage (V_RRM) quad-configuration bridge rectifier in DBLS package, featuring 1.7 V max forward voltage at 1 A and 75 ns reverse recovery time, designed for high-efficiency AC/DC conversion in compact power adapters and lighting drivers.

For engineers reviewing the HDBLS105G datasheet, HDBLS105G pinout, HDBLS105G application, or HDBLS105G equivalent, key selection criteria include its 600 V V_RRM, 50 A I_FSM, 150 °C T_J_MAX, UL Recognized status (E-326854), and AEC-Q101 qualification option - all critical for reliability-critical industrial and automotive auxiliary power designs.

Technical Context

The HDBLS105G integrates four silicon diodes in a single-phase full-wave bridge configuration with common-cathode and common-anode terminals, enabling direct AC-to-DC rectification without external interconnects. Its 75 ns trr and 1.7 V VF support high-frequency switching up to 100 kHz in SMPS topologies while maintaining low conduction and switching losses.

Thermally, it delivers R_θJL = 15 °C/W and R_θJA = 40 °C/W, allowing 1 A continuous operation at ambient temperatures up to 95 °C with minimal heatsinking. The DBLS package uses matte tin-plated leads compliant with J-STD-002 and meets JESD201 Class 2 whisker resistance.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	600 V - supports input rectification from 424 V_RMS AC mains (e.g., 240 VAC + 20% surge)
I_F	1 A continuous - rated for sustained output current in 5–15 W adapter and LED driver applications
I_FSM	50 A (8.3 ms) - withstands inrush surges during cold-start of capacitive-input SMPS
V_F	≤1.7 V @ 1 A, 25°C - limits conduction loss to ≤1.7 W per device at full load
t_rr	75 ns - enables efficient operation in 50–100 kHz flyback and resonant converters
T_J_MAX	150 °C - permits operation in enclosed, thermally constrained environments like LED troffers
R_θJL	15 °C/W - allows direct PCB copper pour thermal coupling to reduce junction temperature rise

Equivalent & Alternatives

The following parts are listed as comparable options for similar bridge rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
GBU6K (ON Semiconductor)	Same 1 A / 600 V rating, but GBU package (larger footprint, higher R_θJA = 50 °C/W)	Less suitable for ultra-thin adapters due to 2.3 mm height vs. DBLS 1.6 mm	Prefer HDBLS105G where board space and thermal resistance are constrained
MB10F (Diodes Inc.)	Lower V_F (1.1 V typ), but only 35 A I_FSM and no AEC-Q101 option	Acceptable for consumer-grade adapters but not automotive or industrial surge-heavy use	Choose HDBLS105G when 50 A surge capability or automotive qualification is required

Compared with GBU6K and MB10F, the HDBLS105G offers superior thermal performance (R_θJA = 40 °C/W), lower profile, and optional AEC-Q101 qualification - making it optimal for space-constrained, high-reliability AC/DC front-ends where surge immunity and long-term stability are prioritized.

FAQ

What is the maximum repetitive peak reverse voltage (V_RRM) of the HDBLS105G?

The HDBLS105G has a V_RRM of 600 V, confirmed in the Absolute Maximum Ratings table across all versions HDBLS101G–HDBLS107G. This value is laser-marked as "HDBLS105G" on the device body and corresponds to the fifth entry in the V_RRM row (50/100/200/400/600/800/1000 V). It supports safe operation with 424 V_RMS AC inputs including margin for line surges.

Is the HDBLS105G RoHS and halogen-free compliant?

Yes, the HDBLS105G is RoHS compliant and halogen-free per IEC 61249-2-21, as explicitly stated in the FEATURES section. The "G" suffix denotes green compound, and the DBLS molding compound meets UL 94V-0 flammability rating. These compliance attributes apply to all variants in the HDBLS101G–HDBLS107G family, including HDBLS105G.

Does the HDBLS105G have AEC-Q101 qualification?

The base HDBLS105G is not AEC-Q101 qualified, but the pin-compatible variant HDBLS105GH is explicitly listed as AEC-Q101 qualified in the Ordering Information table. The "H" suffix denotes this qualification, and both parts share identical electrical and thermal specifications - only reliability testing and traceability differ.

What is the forward voltage (V_F) of the HDBLS105G at 1 A and 25°C?

The HDBLS105G has a maximum forward voltage of 1.7 V at I_F = 1 A and T_J = 25°C, as specified in the Electrical Specifications table under "Forward voltage per diode" for HDBLS105G–HDBLS107G. This value is measured with 0.3 ms pulse width and applies to each diode within the bridge.

What is the reverse recovery time (t_rr) of the HDBLS105G?

The HDBLS105G has a maximum reverse recovery time of 75 ns, tested at I_F = 0.5 A, I_R = 1.0 A, and I_rr = 0.25 A, as documented in the Electrical Specifications table. This t_rr value is shared with HDBLS106G and HDBLS107G and enables efficient high-frequency rectification in modern SMPS designs.
