Product details
Overview
DBLS103GH from Taiwan Semiconductor is a 1A, 200V repetitive peak reverse voltage (VRRM) AEC-Q101 qualified standard bridge rectifier in DBLS package, featuring 40A peak forward surge current (IFSM), 1.1V max forward voltage at 1A, and junction-to-lead thermal resistance of 15°C/W. It serves as AC-to-DC conversion core in compact power adapters and lighting drivers.
For engineers reviewing the DBLS103GH datasheet, DBLS103GH pinout, DBLS103GH application, or DBLS103GH equivalent, key selection criteria include VRRM=200V, IFSM=40A, AEC-Q101 qualification, UL recognition (E-326854), and DBLS surface-mount package compatibility with automated assembly.
Technical Context
This quad-configuration bridge rectifier integrates four silicon diodes in a single molded plastic DBLS package with matte tin-plated leads. Its design supports high-reliability operation up to 150°C junction temperature and meets JESD201 Class 2 whisker resistance and J-STD-020 Level 1 moisture sensitivity requirements.
The device delivers 1A average forward current with low 1.1V forward voltage drop per diode at 25°C, enabling efficient power conversion in space-constrained SMPS designs. Reverse leakage remains ≤2µA at 25°C and ≤100µA at 125°C under rated reverse voltage.

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, IFSM=120A, larger GBU package (10.5×14.5mm vs DBLS 7.1×5.2mm) | Higher voltage/surge margin but requires PCB area increase and thermal redesign | Choose when >200V blocking or >40A surge headroom is required |
| MB10F (Diodes Inc.) | VRRM=1000V, IFSM=30A, same 1A IF rating, smaller MB package (7.1×5.2mm identical footprint) | Over-spec'd VRRM increases cost; lower IFSM limits inrush tolerance | Choose only if 1000V isolation is mandated by safety agency requirements |
Compared with GBU4K and MB10F, DBLS103GH offers optimal balance of 200V rating, 40A surge capability, AEC-Q101 qualification, and compact DBLS footprint-making it ideal for cost-sensitive, space-constrained, and automotive-adjacent power supplies where exact VRRM matching matters.

FAQ
What is the peak repetitive reverse voltage rating for DBLS103GH?
The DBLS103GH has a repetitive peak reverse voltage (VRRM) rating of 200 V, verified per Taiwan Semiconductor's DBLS101G–DBLS107G datasheet Version P2103. This value defines the maximum AC voltage the device can block across its AC terminals during normal operation without entering avalanche breakdown, making DBLS103GH suitable for universal-input (85–265VAC) power supplies where peak line voltage reaches ~375V and derating is applied.
Is DBLS103GH qualified for automotive applications?
Yes, DBLS103GH is explicitly AEC-Q101 qualified, as 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 temperature cycling, high-temperature operating life, and unbiased highly accelerated stress testing-ensuring DBLS103GH meets reliability requirements for under-hood and cabin electronics where ambient temperatures range from –40°C to +125°C.
What is the forward voltage drop specification for DBLS103GH at rated current?
DBLS103GH exhibits a maximum forward voltage (VF) of 1.1 V per diode at IF = 1 A and TJ = 25°C, per the Electrical Specifications table in the datasheet. This value reflects conduction loss under typical operating conditions and directly impacts efficiency in low-voltage-output power supplies; actual VF rises slightly with junction temperature and decreases marginally at lower currents.
Does DBLS103GH require moisture sensitivity baking before reflow soldering?
No, DBLS103GH 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 placed directly into reflow without pre-baking. This eliminates process steps and reduces risk of popcorn cracking during assembly-confirmed in the Mechanical Data section of the DBLS101G–DBLS107G datasheet.
What packaging and reel quantity is offered for DBLS103GH?
DBLS103GH is supplied in tape-and-reel packaging with 1,500 units per reel, consistent with the Ordering Information table in the datasheet. The "H" suffix denotes AEC-Q101 qualification, while the DBLS package type ensures compatibility with standard pick-and-place equipment and reflow profiles for surface-mount assembly of the DBLS103GH.
