Product details
Overview
DBLS153G from Taiwan Semiconductor is a 1.5A, 200V repetitive peak reverse voltage (VRRM) standard bridge rectifier in DBLS surface-mount package, featuring 50A peak surge current (IFSM), 1.10V max forward voltage at 1.5A, and AEC-Q101 qualification option. It serves as AC-to-DC conversion core in compact power adapters and lighting drivers.
For engineers reviewing the DBLS153G datasheet, DBLS153G pinout, DBLS153G application, or DBLS153G equivalent, key selection criteria include VRRM rating, thermal resistance (RθJL = 15°C/W), moisture sensitivity level (MSL 1), UL recognition (E-326854), and RoHS/halogen-free compliance for automotive-grade and industrial PCB designs.
Technical Context
The DBLS153G integrates four silicon diodes in a single-phase full-wave bridge configuration with quad-terminal layout. Its 200V VRRM rating targets mid-voltage AC input stages where higher voltage margins than 100V parts are required but 400V+ overhead is unnecessary.
Thermal performance is defined by RθJL = 15°C/W and RθJA = 40°C/W, enabling reliable operation up to TJ = 150°C. The device supports 8.3ms half-sine surge events (IFSM = 50A) and exhibits IR ≤ 2 µA at 25°C and ≤ 500 µA at 125°C under rated reverse voltage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Maximum non-repetitive reverse voltage the bridge withstands without breakdown; defines AC input voltage range compatibility. |
| IF | 1.5 A - Continuous average forward current per bridge; sets DC output capability in SMPS and adapter designs. |
| IFSM | 50 A - Peak non-repetitive surge current for 8.3 ms; determines robustness against line transients and inrush events. |
| VF (max) | 1.10 V - Maximum forward voltage drop per diode at 1.5 A and 25°C; directly impacts conduction loss and thermal design. |
| RθJL | 15 °C/W - Junction-to-lead thermal resistance; enables direct heatsinking via PCB copper pour or metal-core board. |
| MSL | Level 1 - No floor life limitation before reflow; allows unlimited storage and standard SMT assembly without baking. |

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) | Same 1.5A/200V rating, but through-hole GBU package; RθJA ≈ 50°C/W; no AEC-Q101 option. | Requires PCB through-hole mounting and larger board area; unsuitable for fully SMT production. | Select when legacy board reuse or manual repair is prioritized over miniaturization and automotive qualification. |
| DBLS153GH (Taiwan Semiconductor) | Identical electrical specs and DBLS package; adds AEC-Q101 qualification and enhanced traceability. | Required for automotive interior modules (e.g., infotainment power supplies) and industrial systems demanding extended reliability validation. | Select when functional equivalence plus automotive-grade stress testing and documentation are mandatory. |
Compared with GBU4K, DBLS153G offers superior thermal performance (RθJL = 15°C/W vs. ~35°C/W typical for GBU), smaller footprint, and MSL 1 handling; compared with DBLS153GH, it lacks AEC-Q101 certification but retains identical electrical and thermal behavior for cost-sensitive industrial use.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) of the DBLS153G?
The DBLS153G has a VRRM rating of 200 V, meaning it can block up to 200 volts of reverse voltage repeatedly without breakdown. This value is fixed per the part number suffix '153' and is confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version M2103). The DBLS153G must not be used in circuits where peak reverse voltage exceeds this limit.
Is the DBLS153G RoHS and halogen-free compliant?
Yes, the DBLS153G is both RoHS compliant and halogen-free in accordance with IEC 61249-2-21. These compliance statements are explicitly declared in the FEATURES section of the Taiwan Semiconductor DBLS151G–DBLS159G datasheet. The halogen-free status applies to the molding compound and plating, supporting environmentally regulated markets and end-of-life recycling requirements for the DBLS153G.
Does the DBLS153G have AEC-Q101 qualification?
The standard DBLS153G is not AEC-Q101 qualified; however, the variant DBLS153GH is specifically qualified to AEC-Q101. The datasheet states "AEC-Q101 qualified available" and confirms the 'H' suffix denotes qualification. Therefore, DBLS153G itself does not carry AEC-Q101 certification - only DBLS153GH does - and must be selected accordingly for automotive applications.
What is the forward voltage (VF) specification for the DBLS153G at rated current?
The DBLS153G has a maximum forward voltage of 1.10 V per diode at IF = 1.5 A and TJ = 25°C, as specified in the Electrical Specifications table. This value is shared across DBLS151G through DBLS157G variants. The DBLS153G's VF directly affects conduction losses and thermal rise in continuous operation, making it critical for efficiency calculations in power supply designs.
What is the moisture sensitivity level (MSL) and reflow profile guidance for DBLS153G?
The DBLS153G is rated MSL Level 1 per J-STD-020, meaning it has unlimited floor life and requires no baking prior to reflow soldering. Its matte tin-plated leads meet J-STD-002 for solderability. This MSL rating simplifies manufacturing logistics and ensures compatibility with standard lead-free reflow profiles, including peak temperatures up to 260°C, without risk of popcorning or delamination for the DBLS153G.
