Product details
Overview
DBLS209GH from Taiwan Semiconductor is a 2 A, 1400 V AEC-Q101-qualified standard bridge rectifier in DBLS package, featuring 50 A peak surge current, 1.30 V max forward voltage at 2 A and 25°C, and UL Recognized (E-326854) construction for automotive-grade power conversion.
For engineers reviewing the DBLS209GH datasheet, DBLS209GH pinout, DBLS209GH application, or DBLS209GH equivalent, key selection criteria include repetitive peak reverse voltage (1400 V), junction-to-lead thermal resistance (15 °C/W), moisture sensitivity level (J-STD-020 Level 1), and AEC-Q101 qualification status for under-hood reliability.
Technical Context
This quad-configuration bridge rectifier integrates four silicon diodes in a single DBLS molded plastic package with matte tin-plated leads. It operates across –55°C to +150°C junction temperature range and supports 8.3 ms half-sine surge events up to 50 A (I²t = 10.3 A²s).
Designed for high-reliability DC output generation, it delivers stable reverse blocking up to 1400 V (VRRM), low forward conduction loss (VF ≤ 1.30 V @ 2 A), and meets JESD201 Class 2 whisker resistance and RoHS/halogen-free (IEC 61249-2-21) requirements.

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU15K-E3/54 (Vishay) | Same 2 A / 1400 V rating, but GBU package (larger footprint, higher RθJA = 50 °C/W), no AEC-Q101 qualification. | Suitable for non-automotive industrial adapters where board space and qualification are less critical. | Choose when UL recognition and thermal performance are prioritized over AEC-Q101 compliance. |
| GBU15J-E3/54 (Vishay) | 1000 V VRRM (not 1400 V); otherwise identical package, current rating, and thermal specs. | Limited to lower-input-voltage applications (e.g., 120 VAC-only systems) due to reduced reverse voltage margin. | Select only if system peak line voltage remains below 700 V DC after rectification. |
Compared with GBU15K-E3/54 and GBU15J-E3/54, DBLS209GH offers superior thermal resistance (15 vs. 50 °C/W), AEC-Q101 qualification, and halogen-free compliance-making it optimal for space-constrained, high-reliability automotive and industrial designs where reverse voltage margin and long-term stability are critical.

FAQ
What is the maximum junction temperature rating for DBLS209GH?
The DBLS209GH has a maximum junction temperature (TJ max) of +150°C. This rating allows continuous operation in high-ambient environments such as automotive engine compartments or enclosed LED drivers. The device's 15 °C/W junction-to-lead thermal resistance supports effective heat transfer to the PCB, and its thermal derating curve confirms stable performance up to this limit when proper copper area and airflow are maintained. DBLS209GH must not exceed this temperature under any operating condition.
Is DBLS209GH pin-compatible with other DBLS2xxG variants?
Yes, all DBLS2xxG and DBLS2xxGH parts-including DBLS209GH-share identical DBLS package dimensions, terminal layout, and pinout (AC1, AC2, +DC, –DC). Voltage ratings differ across the family (50 V to 1400 V), but mechanical and electrical interface compatibility is maintained. Therefore, DBLS209GH can be substituted in the same footprint as DBLS201GH through DBLS208GH, provided the higher VRRM does not introduce unintended parasitic effects in low-voltage designs.
Does DBLS209GH meet automotive qualification standards?
Yes, DBLS209GH is explicitly AEC-Q101 qualified, as indicated by the "H" suffix in its ordering code. This qualification covers stress tests including HTSL, TC, UHAST, and bond wire pull, validating suitability for automotive power electronics such as body control modules, lighting drivers, and infotainment power supplies. The DBLS209GH datasheet (Version J2103) confirms full compliance, distinguishing it from non-H variants like DBLS209G.
What is the forward voltage specification for DBLS209GH at rated current?
DBLS209GH specifies a maximum forward voltage (VF) of 1.30 V per diode at IF = 2 A and TJ = 25°C, measured under pulse conditions (PW = 0.3 ms). This value reflects worst-case conduction loss in the rectifier leg and directly impacts system efficiency and thermal design. At elevated junction temperatures (e.g., 125°C), VF decreases slightly, but total bridge drop remains within 2.6 V under full load, supporting efficient bulk DC generation in compact power supplies.
How is moisture sensitivity managed for DBLS209GH during PCB assembly?
DBLS209GH is rated at Moisture Sensitivity Level (MSL) 1 per J-STD-020, meaning it may be stored indefinitely at ≤30°C/85% RH and subjected to standard SMT reflow profiles-including lead-free (260°C peak) -without preconditioning or baking. This eliminates moisture-related popcorning risk and simplifies manufacturing logistics. The DBLS package's molded plastic construction and matte tin plating further ensure solderability and long-term shelf life without dry-pack requirements.
