Product details

Overview

HDBLS107GH from Taiwan Semiconductor is a 1 A, 1000 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 500 µA max reverse current at 125°C, designed for high-efficiency AC/DC conversion in automotive-grade power supplies.

For engineers reviewing the HDBLS107GH datasheet, HDBLS107GH pinout, HDBLS107GH application, or HDBLS107GH equivalent, key selection criteria include its AEC-Q101 qualification, 50 A I_FSM, 75 ns reverse recovery time, R_θJA = 40 °C/W thermal resistance, and suitability for high-reliability lighting and adapter designs requiring 1000 V blocking capability.

Technical Context

This device integrates four fast-recovery diodes in a single DBLS surface-mount package with common-cathode/common-anode topology, enabling full-wave rectification without external interconnection. Its 75 ns trr and low 1.7 V V_F support high-frequency switching up to 100 kHz in SMPS topologies.

The HDBLS107GH meets JESD201 Class 2 whisker resistance, UL 94V-0 mold compound, and moisture sensitivity level 1 per J-STD-020 - confirming robustness for reflow-soldered automotive and industrial PCB assemblies.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
GBU10K	Same 1 A / 1000 V rating but TO-220AC package; 1.1 V V_F typ., 100 ns t_rr; no AEC-Q101 qualification	Requires through-hole mounting and heatsink; unsuitable for automotive PCB-level qualification	Select when cost-sensitive industrial designs prioritize lower V_F over surface-mount density and automotive compliance
DF10M	DBLS package, 1 A / 1000 V, AEC-Q101 qualified, but 2.0 V V_F max and 100 ns t_rr	Higher conduction and switching losses reduce efficiency in high-frequency adapters	Choose only if legacy design reuse mandates identical thermal profile and footprint without performance upgrade

Compared with GBU10K and DF10M, the HDBLS107GH delivers superior high-frequency efficiency via 75 ns t_rr and lower V_F, while maintaining AEC-Q101 compliance and DBLS SMT compatibility - making it optimal for next-generation compact, automotive-qualified power supplies.

FAQ

What does the 'H' suffix in HDBLS107GH signify?

The 'H' suffix in HDBLS107GH indicates full AEC-Q101 qualification - verified across temperature cycling, mechanical shock, humidity bias, and high-temperature operating life tests per automotive electronics reliability standards. This distinguishes HDBLS107GH from the non-H variant HDBLS107G and confirms its suitability for under-hood and cabin applications where HDBLS107GH must operate continuously at 125°C junction temperature.

Is HDBLS107GH pin-compatible with other DBLS-series rectifiers like HDBLS105GH?

Yes, all HDBLS1xxGH devices share identical DBLS package dimensions, pad layout, and 4-pin terminal configuration (AC1, AC2, +, –), enabling direct PCB footprint reuse across the 50–1000 V V_RRM family. The HDBLS107GH maintains the same mechanical interface as HDBLS105GH, though its higher 1000 V rating and 1.7 V V_F reflect optimized die design for elevated voltage stress.

What is the maximum recommended PCB copper area for thermal relief with HDBLS107GH at 1 A continuous load?

At 1 A continuous current and 25°C ambient, HDBLS107GH achieves thermal equilibrium with ≤70°C junction temperature using 1 in² (645 mm²) of 2-oz copper on the primary side, per its R_θJA = 40 °C/W rating. For sustained 1 A operation above 70°C ambient, adding thermal vias to inner ground planes or localized copper pour beneath the DBLS body further stabilizes HDBLS107GH junction temperature within its +150°C limit.

Does HDBLS107GH support lead-free reflow soldering per JEDEC J-STD-020?

Yes, HDBLS107GH is rated for lead-free reflow per JEDEC J-STD-020, with a peak temperature tolerance of 260°C for 30 seconds and moisture sensitivity level 1 - meaning it can be stored indefinitely at ≤30°C/60% RH without baking. The matte tin-plated leads ensure reliable wetting and intermetallic formation during standard Pb-free reflow profiles used for HDBLS107GH assembly.

How does the 75 ns reverse recovery time of HDBLS107GH impact EMI in high-frequency SMPS designs?

The 75 ns t_rr of HDBLS107GH reduces high-frequency ringing and dv/dt-induced noise during diode turn-off, directly lowering conducted EMI in 65–130 kHz flyback converters. When paired with proper snubberless layout practices, HDBLS107GH enables compliance with CISPR-22 Class B limits without additional RC suppression - a measurable advantage over 100+ ns alternatives like DF10M in noise-sensitive lighting and automotive applications.
