Product details
Overview
DBLS106GH from Taiwan Semiconductor is an AEC-Q101 qualified 1A, 800V standard quad bridge rectifier in DBLS package, with 40A peak surge current (IFSM), 15 °C/W junction-to-lead thermal resistance, and UL Recognized (E-326854) construction - used in automotive-grade AC/DC front-ends and industrial SMPS.
For engineers reviewing the DBLS106GH datasheet, DBLS106GH pinout, DBLS106GH application, or DBLS106GH equivalent, key selection criteria include repetitive peak reverse voltage (800 V), forward voltage per diode (≤1.1 V @ 1 A), reverse leakage (≤2 µA @ 25 °C), thermal performance (RθJL = 15 °C/W), and AEC-Q101 qualification status for automotive reliability validation.
Technical Context
The DBLS106GH integrates four silicon diodes in a single-phase bridge configuration within a molded DBLS plastic package, enabling full-wave rectification without external interconnects. Its AEC-Q101 qualification confirms stress-tested reliability for automotive under-hood environments, including temperature cycling, humidity bias, and mechanical shock compliance.
Thermal design is supported by low RθJL (15 °C/W) and RθJA (40 °C/W), allowing direct PCB heat sinking via leads. The device operates across –55 °C to +150 °C junction range and sustains 40 A non-repetitive surge (8.3 ms half-sine) at rated load - critical for inrush-limited power supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 800 V - maximum repetitive reverse voltage per diode; defines safe AC input voltage ceiling (e.g., 560 VRMS ≈ 800 VPK) |
| IF | 1 A continuous average forward current - determines steady-state power handling in linear or switching rectifier stages |
| IFSM | 40 A - peak non-repetitive surge current (8.3 ms); supports capacitor charging surges in offline SMPS inputs |
| VF | ≤1.1 V @ 1 A, 25 °C - forward voltage drop per diode; sets conduction loss (≈2.2 W total bridge loss at 1 A) |
| RθJL | 15 °C/W - junction-to-lead thermal resistance; enables direct thermal path to PCB copper for passive cooling |
| TJ max | +150 °C - maximum operating junction temperature; allows use in high-ambient automotive engine bay locations |
| AEC-Q101 | Qualified - validated for automotive reliability including HTOL, TC, HAST, and UHAST per AEC standard |
Pinout & Package
Package: DBLS - surface-mount molded plastic case (UL 94V-0), 4-terminal single-phase bridge configuration with polarity marked on top surface. Matte tin-plated leads meet J-STD-002 solderability and JESD201 Class 2 whisker requirements.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| ~ (AC1) | AC input terminal 1 | One of two AC input nodes; connects to transformer secondary or AC line input |
| ~ (AC2) | AC input terminal 2 | Second AC input node; completes full-wave bridge input path |
| + (DC+) | Positive DC output | Rectified positive output node; feeds bulk capacitor or downstream regulator |
| – (DC–) | Negative DC output / common reference | Rectified negative output; serves as system ground reference in unisolated topologies |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive under-hood deployment - includes temperature cycling, high-temp operating life, and biased HAST |
| 40 A IFSM rating | Supports high inrush currents during cold start in 100–240 VAC universal-input power supplies |
| RθJL = 15 °C/W | Enables efficient heat transfer to PCB copper; reduces need for external heatsinks in space-constrained designs |
| UL Recognition E-326854 | Confirms flammability (UL 94V-0), electrical insulation, and long-term safety compliance for end-equipment certification |
| Moisture sensitivity level 1 | Zero floor-life restriction - can be mounted directly after unpacking without baking or dry-pack handling |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU8K (ON Semiconductor) | Same 800 V VRRM, 8 A IF, GBU package (larger footprint, higher IFSM = 350 A) | Higher current capacity; not AEC-Q101 qualified; requires larger PCB area | Select when >1 A average current or higher surge margin is needed; avoid if AEC-Q101 or space constraints apply |
| MB10F (Vishay) | 800 V VRRM, 1 A IF, MB package (smaller than DBLS, IFSM = 30 A, no AEC-Q101) | Compact footprint but lower surge rating and no automotive qualification | Prefer for cost-sensitive consumer adapters where AEC-Q101 and 40 A surge are not required |
Compared with GBU8K and MB10F, the DBLS106GH uniquely combines AEC-Q101 qualification, 40 A surge capability, and compact DBLS footprint - making it optimal for space-constrained automotive and industrial rectifiers needing certified reliability without over-spec'ing current rating.

FAQ
What does the 'H' suffix in DBLS106GH signify?
The 'H' suffix in DBLS106GH explicitly denotes AEC-Q101 qualification - confirmed by Taiwan Semiconductor's test reports and UL Recognition File #E-326854. This distinguishes DBLS106GH from the non-automotive DBLS106G variant, which lacks stress-test validation for automotive temperature, humidity, and lifetime requirements. DBLS106GH must be specified where automotive reliability is contractually or functionally mandated.
What is the maximum continuous forward current rating for DBLS106GH?
The DBLS106GH has a rated average forward current (IF) of 1 A at TA = 40 °C with adequate PCB copper area. Derating is required above 40 °C ambient; at 80 °C, the usable IF drops to approximately 0.65 A per the forward current derating curve in the DBLS101G–DBLS107G datasheet. This rating applies to the entire bridge, not per diode.
Is DBLS106GH compatible with lead-free reflow soldering processes?
Yes, DBLS106GH supports lead-free reflow soldering per J-STD-020. Its matte tin-plated leads are solderable per J-STD-002, and the DBLS package is rated for moisture sensitivity level 1 - meaning it may be placed directly after opening without baking. Peak reflow temperature must not exceed 260 °C for ≤60 seconds, consistent with standard Pb-free profiles.
How does the DBLS106GH's thermal resistance compare to industry-standard bridge packages?
DBLS106GH achieves RθJL = 15 °C/W, significantly lower than typical GBU (≈25 °C/W) or KBP (≈20 °C/W) packages. This is enabled by its optimized DBLS leadframe geometry and direct thermal path from die to outer leads. As a result, DBLS106GH delivers ~30% lower junction temperature rise than comparable 1A bridges under identical 1A DC load and PCB copper conditions.
Does DBLS106GH meet halogen-free and RoHS requirements?
Yes, DBLS106GH complies with both RoHS Directive 2011/65/EU and halogen-free requirements per IEC 61249-2-21. Taiwan Semiconductor certifies that brominated flame retardants (BFRs), chlorine, fluorine, iodine, and bromine are each below 900 ppm, and total halogens are <1500 ppm. This is documented in TSC's material declarations and supported by third-party lab reports.
