Product details
Overview
DBLS201GH from Taiwan Semiconductor is a 2 A, 50 V repetitive peak reverse voltage (VRRM) standard quad bridge rectifier in DBLS surface-mount package, featuring 50 A peak surge current (IFSM), 1.15 V max forward voltage at 2 A, and AEC-Q101 qualification for automotive-grade reliability - used in compact AC/DC front-end stages of LED drivers and industrial adapters.
For engineers reviewing the DBLS201GH datasheet, DBLS201GH pinout, DBLS201GH application, or DBLS201GH equivalent, key selection criteria include VRRM margin vs. input transient clamping, thermal resistance (RθJL = 15 °C/W) for board-level power dissipation, AEC-Q101 compliance status, and tape-and-reel packaging for automated assembly.
Technical Context
This device integrates four silicon diodes in a single-phase full-wave bridge configuration with common-cathode and common-anode terminals externally accessible. It operates across -55 °C to +150 °C junction temperature range and supports 8.3 ms half-sine surge events up to 50 A without fusing (I²t = 10.3 A²s).
The DBLS201GH uses matte tin-plated leads compliant with J-STD-002 solderability and JESD201 Class 2 whisker resistance, housed in UL 94V-0 molded plastic with moisture sensitivity level 1 per J-STD-020 - enabling reflow compatibility and long-term PCB reliability in high-humidity environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 50 V - defines maximum continuous reverse blocking capability; sets minimum input voltage derating margin for 24 VAC or 36 VDC systems. |
| IF | 2 A average forward current - determines steady-state power handling; requires ≥15 mm² copper pour for thermal relief at full load. |
| IFSM | 50 A peak surge current - withstands inrush into capacitive loads or lightning-induced transients in offline SMPS inputs. |
| VF | ≤1.15 V at 2 A, 25 °C - limits conduction loss to ≤2.3 W per bridge; critical for efficiency in low-voltage, high-current adapters. |
| RθJL | 15 °C/W - enables direct heat transfer from junction to PCB pad; allows 100% thermal performance without heatsink in 2-layer boards. |
| TJ max | +150 °C - supports operation in under-hood automotive modules or enclosed industrial enclosures without active cooling. |
| AEC-Q101 | Qualified - meets stress test requirements for automotive electronics including HTOL, TC, and UHAST; required for Tier-1 supplier BOMs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU2K (ON Semiconductor) | Same 2 A / 50 V rating but GBU through-hole package; higher RθJA (50 °C/W) and no AEC-Q101 qualification. | Not suitable for automotive or high-density SMT designs; limited to legacy through-hole production lines. | Select only if board layout reserves through-hole footprint and AEC-Q101 is not required. |
| MB2S (Vishay) | 2 A / 50 V, SMB package; lower IFSM (30 A), no UL recognition or AEC-Q101; RθJL = 20 °C/W. | Acceptable for cost-sensitive consumer adapters but lacks safety certification and surge robustness for industrial use. | Choose when budget constraints outweigh certification needs and surge immunity is secondary. |
Compared with GBU2K and MB2S, the DBLS201GH uniquely combines AEC-Q101 qualification, UL recognition, MSL-1 handling, and 50 A surge rating in a compact DBLS SMT package - making it the only option qualified for automotive interior lighting and certified industrial adapter designs requiring both safety and reliability.

FAQ
What is the peak repetitive reverse voltage rating for DBLS201GH?
The DBLS201GH has a repetitive peak reverse voltage (VRRM) rating of 50 V. This value defines the maximum instantaneous reverse voltage the device can block continuously without breakdown. It is specified per diode within the bridge and applies across the AC input terminals (~AC1 to ~AC2) under normal operating conditions at TJ ≤ 150 °C. Exceeding this rating risks irreversible avalanche failure.
Is DBLS201GH qualified to AEC-Q101 standards?
Yes, DBLS201GH is explicitly AEC-Q101 qualified, as confirmed by Taiwan Semiconductor's ordering code suffix "H" and documentation in Version J2103. This qualification covers stress tests including high-temperature operating life (HTOL), temperature cycling (TC), and unbiased highly accelerated stress test (UHAST), validating its suitability for automotive electronic control units and lighting modules.
What is the forward voltage drop of DBLS201GH at rated current?
At IF = 2 A and TJ = 25 °C, the DBLS201GH exhibits a maximum forward voltage (VF) of 1.15 V per diode. Since the bridge conducts through two diodes in series during each half-cycle, total conduction loss reaches up to 2.3 V drop across the output terminals (+DC to -DC) at full load - directly impacting thermal design and efficiency in low-voltage power supplies.
Does DBLS201GH require baking before reflow soldering?
No, DBLS201GH does not require baking prior to reflow soldering because it is rated Moisture Sensitivity Level 1 (MSL-1) per J-STD-020. This means it has unlimited floor life at ≤30 °C/60% RH and may be placed directly into standard lead-free reflow profiles without preconditioning - reducing manufacturing overhead and preventing moisture-related defects like popcorn cracking.
What packaging format is available for DBLS201GH?
DBLS201GH is supplied in tape-and-reel packaging with 1,500 units per reel, compatible with high-speed automated pick-and-place equipment. The DBLS package features gull-wing leads and conforms to JEDEC standard outlines for surface-mount bridge rectifiers. No tray or bulk packaging options are specified for this part number in Taiwan Semiconductor's official documentation.
