Product details
Overview
DABS1100-13 from Diodes Incorporated is a 1A, 100V peak repetitive reverse voltage (VRRM) Schottky bridge rectifier in ABS surface-mount package, featuring 0.85V max forward voltage at 1A/25°C and 10µA max reverse leakage at 100V/25°C, used for AC-to-DC conversion in compact energy-saving lamps and mobile battery chargers.
For engineers reviewing the DABS1100-13 datasheet, DABS1100-13 pinout, DABS1100-13 application, or DABS1100-13 equivalent, key selection criteria include low VF for efficiency-critical 1A bridge rectification, thermal resistance (RθJA = 75°C/W), RoHS-compliant lead-free plating, and molded plastic ABS package suitability for high-density PCB layouts.
Technical Context
This Schottky bridge integrates four diodes in a single-phase full-wave configuration, enabling direct AC input rectification without external wiring. Its low 0.85V forward drop at rated current reduces conduction loss, while 100V VRRM supports universal input (90–264VAC) front-end designs with margin.
Thermal performance is defined by RθJA = 75°C/W on standard 1oz copper (2mm × 2mm pad), and RθJC = 13°C/W enables effective heat transfer to PCB copper planes. Junction temperature range spans –55°C to +150°C, supporting operation in enclosed lamp housings and charger adapters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Withstands peak reverse voltage up to 100V without breakdown, suitable for 70V RMS AC inputs with safety margin. |
| IO (AV) | 1 A - Continuous average output current capability under standard heatsinking conditions (RθJA = 75°C/W). |
| VF Max | 0.85 V @ 1A, 25°C - Low conduction loss improves efficiency in space-constrained 5–12W offline power supplies. |
| IR Max | 10 µA @ 100V, 25°C - Minimal reverse leakage preserves no-load efficiency and prevents capacitor discharge in standby mode. |
| RθJA | 75 °C/W - Thermal resistance to ambient defines required PCB copper area for safe operation at full load. |
| CT | 75 pF @ 4V, 1MHz - Junction capacitance impacts EMI filtering design and high-frequency switching noise in SMPS front ends. |
Pinout & Package
Package: ABS surface-mount molded plastic package (4.00 mm × 1.20 mm body, 7.20 mm total length), UL 94V-0 rated, lead-free matte tin plating, polarity marked on body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AC1 | AC Input Terminal 1 | One of two alternating current input pins; connects to live or neutral side of transformer secondary or AC line. |
| AC2 | AC Input Terminal 2 | Second AC input pin; completes full-wave bridge input path with AC1. |
| +OUT | Positive DC Output | Rectified positive output node; delivers pulsating DC to bulk capacitor and downstream regulator. |
| –OUT | Negative DC Output / Common Return | DC return path; serves as reference ground for output stage and feedback network. |
Key Features
| Feature | Design Value |
|---|---|
| Low VF Schottky Bridge | 0.85V max at 1A ensures ≥5% higher efficiency vs. silicon bridge at light-to-moderate loads in 5–10W adapters. |
| RoHS & Halogen-Free | Lead-free matte tin plating and <900ppm Br/Cl, <1000ppm Sb meet global environmental compliance mandates for consumer electronics. |
| ABS Molded Plastic Package | Compact 4.0 × 1.2 mm footprint enables high-density layout in slim LED lamp drivers and USB-C chargers. |
| High Surge Rating | 30A non-repetitive peak forward surge current (8.3ms half-sine) withstands cold-start inrush into bulk capacitors. |
Applications
| Energy-Saving Lamps | Mobile Battery Chargers |
|---|---|
Use Scenario: Compact LED retrofit lamps with integrated AC/DC driver operating directly from mains (90–264VAC). IC Role / Device Role / Timing Role: Full-wave Schottky bridge rectifier converting AC input to pulsating DC before buck/buck-boost regulation. Use Value: 0.85V VF minimizes self-heating in thermally constrained lamp bases, extending electrolytic capacitor life and maintaining lumen output over time. | Use Scenario: Wall-mounted USB-A/USB-C chargers delivering 5–12W output with minimal footprint and no heatsink. IC Role / Device Role / Timing Role: Primary-side bridge rectifier in flyback or quasi-resonant converter front end. Use Value: 10µA IR at 100V reduces no-load power consumption below 30mW, meeting DOE Level VI and EU CoC Tier 2 requirements. |
| Compact AC/DC Adapters | Industrial Control Power Supplies |
Use Scenario: DIN-rail or PCB-mounted 5–10W auxiliary power supplies for sensors and PLC I/O modules. IC Role / Device Role / Timing Role: Input rectification stage feeding isolated DC/DC converter with wide input range. Use Value: –55°C to +150°C operating range supports reliable operation in unventilated enclosures exposed to ambient temperatures up to 70°C. | Use Scenario: Low-power auxiliary rails (±12V, 5V) in motor drives and HMI panels requiring long-term reliability. IC Role / Device Role / Timing Role: Mains-fed rectifier supplying bias power to gate drivers and microcontrollers. Use Value: 75°C/W RθJA allows thermal design using only PCB copper pour-no discrete heatsink needed-reducing BOM cost and assembly steps. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SB1100-TB | Same 100V VRRM, 1A IO, but TO-277 package (larger footprint, higher RθJA ≈ 90°C/W). | Requires more PCB area; less suitable for ultra-thin lamp drivers where ABS height (1.80 mm) is critical. | Select when higher surge robustness is prioritized over size, or when legacy TO-277 footprint compatibility is required. |
| MB110S | 100V VRRM, 1A IO, but standard silicon bridge (VF ≈ 1.1V); higher conduction loss and lower TJ max (+125°C). | Higher VF increases thermal stress in sealed environments; not suitable for >60°C ambient without derating. | Select only if cost sensitivity outweighs efficiency and thermal performance, and ambient temperature remains <45°C. |
Compared with SB1100-TB and MB110S, DABS1100-13 delivers superior thermal efficiency in space-limited designs due to its low-profile ABS package and Schottky VF, while maintaining identical electrical ratings-making it optimal for modern energy-efficient, miniaturized AC/DC converters.

FAQ
What is the maximum junction temperature for DABS1100-13?
The DABS1100-13 has a specified operating junction temperature range of –55°C to +150°C. This rating is validated per JEDEC standards and confirmed in the datasheet's Thermal Characteristics table. It enables reliable operation in sealed lamp housings and enclosed charger adapters where internal ambient may exceed 70°C, provided PCB thermal design maintains junction temperature within limits.
Is DABS1100-13 automotive-qualified?
No, DABS1100-13 is not AEC-Q101 qualified. The datasheet explicitly states that automotive-grade versions require specific change control, PPAP capability, and IATF 16949 manufacturing-none of which apply to this standard commercial-grade part. For automotive applications, Diodes offers separate AEC-Q101-certified Schottky bridges such as the ABS1100Q series.
Can DABS1100-13 replace a standard silicon bridge like KBP206?
Only in limited cases: DABS1100-13 matches KBP206's 100V VRRM and 2A IO rating, but its 1A average current rating is half that of KBP206. Its Schottky architecture lowers VF (0.85V vs. ~1.1V), improving efficiency-but thermal derating is stricter due to lower surge tolerance (30A vs. 60A) and smaller package. Not a drop-in replacement without circuit review.
What is the recommended PCB pad layout for ABS package?
Diodes specifies a 2mm × 2mm copper pad per terminal for thermal performance (RθJA = 75°C/W). Exact dimensions and solder mask clearance are published in the ABS package outline drawing (Document #PO-ABS) on diodes.com/package-outlines.html. Use IPC-7351B "Gull Wing" land pattern with 0.5mm solder paste stencil aperture for optimal reflow yield and mechanical reliability.
