Product details
Overview
DF10S-T from Diodes Incorporated is a 1.0A surface-mount standard recovery bridge rectifier with 1000V peak repetitive reverse voltage (VRRM), 1.1V maximum forward voltage at 1.0A, and 10µA maximum reverse leakage current at 25°C. It features glass-passivated die construction, 50A non-repetitive surge capability, and is qualified for automotive-grade change control per AEC-Q101 requirements when specified.
For engineers reviewing the DF10S-T datasheet, DF10S-T pinout, DF10S-T application, or DF10S-T equivalent, this device serves as a compact, RoHS-compliant, halogen-free bridge rectifier optimized for AC/DC conversion in space-constrained industrial power supplies, LED drivers, and auxiliary power rails where thermal derating to 1.0A at +40°C ambient is required.
Technical Context
This single-phase, full-wave bridge rectifier integrates four silicon diodes in a monolithic DF-S package. Its standard recovery characteristic (trr not specified, typical for standard recovery) supports line-frequency (50/60Hz) operation with capacitive load derating (−20% current rating). Thermal resistance is 40°C/W junction-to-ambient on a 5.0mm² copper pad.
The device operates across −55°C to +150°C junction temperature range and exhibits 25pF typical junction capacitance per element at 1MHz/4V reverse bias. Its I²t fusing rating of 10.4A²s defines short-circuit withstand capability under 8.3ms half-sine surge conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1000 V - Maximum repetitive reverse voltage per diode leg; defines safe AC input voltage ceiling (e.g., ≤707V RMS). |
| IF(AV) | 1.0 A at TA = +40°C - Average forward current rating; requires PCB thermal management above +40°C ambient. |
| VF Max | 1.1 V @ IF = 1.0A - Forward drop per diode element; determines conduction loss (1.1W total for two conducting diodes in series). |
| IR Max | 10 µA @ 25°C - Reverse leakage per element; critical for low-power standby circuits and high-impedance sensing nodes. |
| IFSM | 50 A @ 8.3ms - Non-repetitive surge rating; supports inrush current handling during cold-start of transformer-based supplies. |
| RθJA | 40 °C/W - Junction-to-ambient thermal resistance on standard 5.0mm² pad; sets minimum copper area needed for thermal compliance. |
| CT | 25 pF @ 1MHz, 4V - Junction capacitance per diode; impacts EMI filtering design and high-frequency switching noise coupling. |

Applications
| Industrial AC/DC Power Supplies | LED Driver Auxiliary Rectification |
|---|---|
Use Scenario: Converting 230VAC mains to unregulated DC for offline SMPS controllers in PLC power modules. IC Role / Device Role: Full-wave bridge rectifier providing isolated DC bus prior to PWM controller and flyback transformer. Use Value: 1000V VRRM ensures margin against line surges; 1.1V VF minimizes conduction loss in continuous 1A output designs. | Use Scenario: Generating low-current bias rails for LED driver ICs in outdoor streetlight fixtures. IC Role / Device Role: Secondary-side rectifier converting transformer-isolated AC to stable +12V/−12V for op-amp and gate-drive circuitry. Use Value: Low IR (10µA) prevents standby current drain; DF-S package fits tight spacing between heatsink and driver IC. |
| Automotive Body Control Modules | Appliance Motor Control Auxiliary Power |

IC Role / Device Role: Mains-fed bridge feeding linear regulator that powers MCU, sensors, and triac gate drivers. Use Value: 40°C/W RθJA enables thermal compliance on FR-4 with minimal copper; UL recognition simplifies IEC 60335 certification. |
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 1A/1000V rating but larger GBU package (10.5×14.2mm); higher RθJA (30°C/W on larger pad). | Through-hole mounting only; unsuitable for fully SMT production lines. | Select if legacy through-hole layout exists and thermal margin allows larger footprint. |
| MB10F (Vishay) | 1A/1000V, same DF-S footprint; slightly higher VF (1.15V) and IR (20µA at 25°C). | Identical mounting and PCB land pattern; minor efficiency trade-off in low-IQ systems. | Choose for second-source availability with no layout change; verify leakage impact in battery-backed circuits. |
Compared with GBU4K and MB10F, DF10S-T offers the lowest profile SMT solution with best-in-class leakage and UL recognition, making it optimal for new designs prioritizing automation, space, and regulatory efficiency-while MB10F provides drop-in compatibility and GBU4K suits legacy through-hole builds.

FAQ
What is the maximum operating temperature for DF10S-T?
The DF10S-T has a junction temperature range of −55°C to +150°C and an ambient temperature limit of +40°C for full 1.0A average current rating. Derating begins above +40°C per Figure 1 in DS17001, reaching zero current at +150°C ambient. PCB thermal design must maintain TJ ≤ +150°C under worst-case load and ambient conditions.
Is DF10S-T suitable for use in capacitive-input filter circuits?
Yes, but with mandatory 20% current derating per the datasheet: the rated 1.0A average forward current applies only to resistive or inductive loads. For capacitive-input filters-common in offline SMPS-maximum continuous current must be limited to 0.8A to prevent overheating and premature failure due to high peak charging currents.
Does DF10S-T meet automotive qualification standards?
DF10S-T itself is not pre-qualified to AEC-Q101, but Diodes Incorporated offers AEC-Q101-qualified versions of the DF-S family (e.g., DF10S-AQ) with PPAP documentation, IATF 16949 manufacturing, and enhanced test coverage. Standard DF10S-T may be used in automotive applications only after customer-specific qualification and change control approval.
What is the recommended PCB pad layout for DF10S-T?
Diodes specifies a 5.0mm² copper land area per terminal for thermal resistance measurement (RθJA = 40°C/W). The exact pad dimensions are defined in the DF-S package outline drawing (available at diodes.com/package-outlines.html), with recommended stencil aperture and solder paste volume aligned to J-STD-020 Level 1 moisture sensitivity. Avoid thermal relief on high-current pads to minimize resistance and heating.
