Product details
Overview
DBLS152GH from Taiwan Semiconductor is a 1.5A, 100V repetitive peak reverse voltage (VRRM) AEC-Q101-qualified standard bridge rectifier in DBLS package, featuring 50A peak surge current (IFSM), 1.10V max forward voltage at 1.5A, and UL Recognized File #E-326854 - used in automotive-grade AC/DC adapters and lighting power supplies.
For engineers reviewing the DBLS152GH datasheet, DBLS152GH pinout, DBLS152GH application, or DBLS152GH equivalent, key selection considerations include VRRM=100V, IF=1.5A, AEC-Q101 qualification, thermal resistance RθJL=15°C/W, and DBLS surface-mount quad configuration for space-constrained SMPS designs.
Technical Context
The DBLS152GH integrates four silicon diodes in a single-phase full-wave bridge configuration with common-cathode/common-anode topology. It operates across -55°C to +150°C junction temperature range and supports 8.3ms half-sine surge events up to 50A (IFSM), with fusing I²t rating of 10.3 A²s.
Thermally, it delivers RθJL = 15°C/W (junction-to-lead) and RθJA = 40°C/W (junction-to-ambient), enabling reliable conduction under continuous 1.5A load in PCB-mounted applications without forced airflow. Reverse leakage remains ≤2 µA at 25°C and ≤500 µA at 125°C at rated VR.
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 |
|---|---|---|---|
| GBU4K (ON Semiconductor) | VRRM=400V, IF=4A, larger GBU package (10.1×14.1mm vs DBLS 7.1×5.9mm), no AEC-Q101 qualification | Higher voltage margin but unsuitable for space-constrained automotive modules requiring AEC-Q101 | Select DBLS152GH when board area < 42 mm² and automotive qualification is mandatory. |
| MB10F (Vishay) | VRRM=100V, IF=1.0A, MBF package (6.7×4.9mm), AEC-Q101 qualified, lower IF and IFSM (30A) | Smaller footprint but insufficient surge rating for high-inrush lighting drivers | Choose DBLS152GH where 1.5A continuous and 50A surge are required in same AEC-Q101-compliant form factor. |
Compared with GBU4K and MB10F, DBLS152GH uniquely balances AEC-Q101 compliance, 100V/1.5A/50A ratings, and compact DBLS footprint - making it optimal for automotive and industrial SMPS where qualification, surge resilience, and PCB area are jointly constrained.

FAQ
What is the peak repetitive reverse voltage rating for DBLS152GH?
The DBLS152GH has a repetitive peak reverse voltage (VRRM) rating of 100 V, as confirmed in the Absolute Maximum Ratings table of Taiwan Semiconductor's DBLS151G–DBLS159G datasheet (Version M2103). This value applies per diode leg in the internal bridge configuration and defines the maximum AC input voltage peak the device can block reliably in continuous operation.
Is DBLS152GH qualified to AEC-Q101 standards?
Yes, DBLS152GH is AEC-Q101 qualified - explicitly indicated by the "H" suffix in its ordering code and confirmed in the FEATURES section of the official datasheet. This qualification covers stress tests including high-temperature reverse bias (HTRB), temperature cycling (TC), and highly accelerated stress test (HAST), validating suitability for automotive power electronics.
What is the forward voltage drop of DBLS152GH at rated current?
The DBLS152GH exhibits a maximum forward voltage (VF) of 1.10 V at IF = 1.5 A and TJ = 25°C, per the Electrical Specifications table. This value is measured per diode under pulse conditions (PW = 0.3 ms), and represents the conduction loss contribution of one diode in the bridge path during normal operation.
Does DBLS152GH require moisture sensitivity baking before reflow soldering?
No, DBLS152GH has a moisture sensitivity level (MSL) of 1 per J-STD-020, meaning it has unlimited floor life and does not require baking prior to reflow soldering. This simplifies SMT process flow and eliminates risk of popcorning damage during assembly - a key advantage for high-volume automotive and industrial production.
What is the thermal resistance from junction to lead for DBLS152GH?
The junction-to-lead thermal resistance (RθJL) of DBLS152GH is 15°C/W, as specified in the Thermal Performance section of the datasheet. This low value enables efficient heat transfer from the silicon die through the lead frame to PCB copper pours, supporting sustained 1.5A operation without external heatsinking in typical layouts.
