Product details
Overview
DBLS159GH from Taiwan Semiconductor is a 1.5A, 1400V AEC-Q101-qualified standard quad bridge rectifier in DBLS package, featuring 50A peak surge current, 1.25V max forward voltage at 1.5A/25°C, and 2µA max reverse leakage at 25°C - used in high-voltage AC/DC front-end stages of automotive-grade LED drivers and industrial SMPS.
For engineers reviewing the DBLS159GH datasheet, DBLS159GH pinout, DBLS159GH application, or DBLS159GH equivalent, key selection criteria include repetitive peak reverse voltage (1400V), junction-to-lead thermal resistance (15°C/W), AEC-Q101 qualification status, moisture sensitivity level (J-STD-020 Level 1), and UL recognition (E-326854).
Technical Context
The DBLS159GH integrates four silicon diodes in a single-phase full-wave bridge configuration with common-cathode and common-anode terminals externally accessible. Its 1400V VRRM rating enables direct rectification of 1000VAC line-derived inputs, while the 15°C/W RθJL supports conduction-limited thermal design in compact PCB layouts without heatsinking up to 1.5A continuous.
Designed for automotive and industrial environments, DBLS159GH meets AEC-Q101 stress test requirements including temperature cycling, high-temperature operating life, and unbiased highly accelerated stress testing. Its matte tin-plated leads comply with J-STD-002 solderability and JESD201 Class 2 whisker resistance standards.

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-15F140 | Same 1.5A/1400V rating; TO-220AC package; higher RθJA (50°C/W) and no AEC-Q101 qualification | Requires heatsink above 0.8A; not approved for automotive under-hood use | Select when cost-sensitive industrial designs prioritize legacy through-hole compatibility over thermal density |
| ON Semiconductor GBPC1514 | 15A rated; larger GBPC package; 1400V VRRM; no AEC-Q101 or UL recognition | Over-specified current capacity increases board area and cost; lacks automotive qualification and safety certifications | Choose only if system-level surge testing requires >50A IFSM margin beyond DBLS159GH's 50A rating |

FAQ
What is the peak repetitive reverse voltage rating of DBLS159GH?
The DBLS159GH has a repetitive peak reverse voltage (VRRM) rating of 1400 V. This value is confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version M2103), and defines the maximum instantaneous reverse voltage the device can block repeatedly without breakdown. It enables direct rectification of up to 1000 VAC RMS inputs with appropriate safety margin.
Is DBLS159GH qualified to AEC-Q101 standards?
Yes, DBLS159GH is explicitly AEC-Q101 qualified, as indicated by the "H" suffix in its ordering code and confirmed in the FEATURES section of the Taiwan Semiconductor datasheet. This qualification covers stress tests including temperature cycling, high-temperature operating life, and unbiased HAST - validating suitability for automotive power electronics applications such as LED headlamp drivers and engine control auxiliary supplies.
What is the forward voltage drop of DBLS159GH at rated current?
The DBLS159GH exhibits a maximum forward voltage (VF) of 1.25 V at IF = 1.5 A and TJ = 25°C, per the Electrical Specifications table. This value applies to each conducting diode pair during full-wave rectification. At elevated junction temperatures (e.g., 125°C), VF decreases slightly, but conduction loss remains predictable for thermal modeling in SMPS and adapter designs.
Does DBLS159GH require special handling due to moisture sensitivity?
No, DBLS159GH has a moisture sensitivity level (MSL) of Level 1 per J-STD-020, meaning it may be stored indefinitely at ≤30°C/60% RH and processed using standard SMT reflow profiles without pre-baking or dry-pack requirements. This simplifies manufacturing logistics and reduces assembly risk compared to MSL 3+ components.
What safety certifications does DBLS159GH hold?
DBLS159GH is UL Recognized under File #E-326854, confirming compliance with UL 60950-1 and UL 62368-1 insulation, flammability (UL 94V-0), and construction requirements. It is also RoHS compliant and halogen-free per IEC 61249-2-21 - supporting global safety certification efforts for end equipment in automotive, industrial, and medical-adjacent applications.
