Product details
Overview
DF10S from Diodes Incorporated is a 1.0A surface-mount standard recovery bridge rectifier with 1000V peak repetitive reverse voltage, 1.1V max forward voltage at 1.0A, and 10µA max reverse leakage at 25°C. It features glass-passivated die construction, 50A non-repetitive surge capability, and UL recognition (E364304) for use in AC/DC power supplies, LED drivers, and industrial control power stages.
For engineers reviewing the DF10S datasheet, DF10S pinout, DF10S application, or DF10S equivalent, key selection criteria include its 1000V blocking rating, thermal resistance of 40°C/W, surface-mount DF-S package compatibility, and compliance with RoHS, halogen-free, and AEC-Q200-capable manufacturing requirements.
Technical Context
The DF10S integrates four silicon diodes in a single-phase full-wave bridge configuration with internal common-cathode and common-anode nodes. Its standard recovery characteristic (typical trr > 500ns) supports line-frequency rectification without high-frequency switching losses.
Designed for PCB-mounted operation, it uses tin-finished terminals solderable per MIL-STD-202 Method 208 and exhibits 25pF typical junction capacitance per element at 1MHz/4V reverse bias-optimized for low-noise, low-RFI power conversion in 50/60Hz applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1000 V - Maximum peak reverse voltage the device blocks reliably in repetitive AC line conditions |
| IF(AV) | 1.0 A - Average forward current handling capacity at TA = +40°C, defining continuous DC output capability |
| VF Max | 1.1 V @ 1.0A - Forward voltage drop per diode element, directly determining conduction loss and thermal load |
| IR Max | 10 µA @ 25°C - Reverse leakage current per element, critical for high-impedance hold-off and low standby power |
| IFSM | 50 A @ 8.3ms - Surge withstand capability, enabling robustness against inrush currents in transformer-fed supplies |
| RθJA | 40 °C/W - Junction-to-ambient thermal resistance on standard 5.0mm² copper land, guiding heatsinking requirements |
| CT | 25 pF @ 1MHz - Junction capacitance per diode, influencing EMI generation and high-frequency rectifier noise |

Applications
| AC/DC Power Supplies | LED Driver Input Stages |
|---|---|
Use Scenario: Rectifying 50/60Hz AC mains or transformer secondary output into unregulated DC bus. IC Role / Device Role / Timing Role: Full-wave bridge rectifier converting bidirectional AC to pulsating DC prior to filtering and regulation. Use Value: 1000V VRRM ensures margin against line surges; 1.1V VF minimizes conduction loss in cost-sensitive offline supplies. | Use Scenario: Converting AC input to DC for constant-current LED driver ICs in streetlight or commercial lighting. IC Role / Device Role / Timing Role: Primary rectification stage delivering stable DC rail to buck/boost controller and MOSFET switch. Use Value: Low IR (10µA) prevents leakage-induced dimming drift; DF-S package enables high-density LED module layouts. |
| Industrial Control Power Rails | Appliance Motor Drive Auxiliary Supplies |

IC Role / Device Role / Timing Role: Mains-input bridge supplying unregulated DC to LDO or DC-DC converter powering motor control logic. Use Value: 50A IFSM tolerates compressor startup surges; -55°C to +150°C operating range supports harsh appliance environments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU10K (ON Semiconductor) | Same 1000V VRRM and 1.0A IF, but GBU package (larger, through-hole); VF = 1.05V typ | Requires PCB redesign for through-hole mounting; higher thermal mass suits higher ambient temp | Select when legacy through-hole assembly or higher surge margin (60A IFSM) is required |
| MB10F (Vishay) | Same DF-S footprint, 1000V VRRM, but VF = 1.15V max; IR = 5µA @ 25°C | Lower leakage benefits ultra-low-power standby; slightly higher VF increases conduction loss | Select when minimizing reverse leakage is prioritized over forward loss in always-on systems |
Compared with GBU10K and MB10F, DF10S offers optimal balance of surface-mount compatibility, 1.1V VF, and UL recognition-making it preferred for new SMT-based industrial and lighting designs requiring certification-ready components.

FAQ
What is the maximum allowable ambient temperature for continuous 1.0A operation?
DF10S delivers 1.0A average forward current only at TA = +40°C, per the datasheet derating curve. At +85°C ambient, the usable current drops to approximately 0.6A due to thermal limitations imposed by its 40°C/W RθJA and 150°C max junction temperature. Forced airflow or copper pour can extend usable current at elevated temperatures.
Is DF10S qualified for automotive applications?
DF10S is manufactured in IATF 16949-certified facilities and supports PPAP documentation, but it is not formally AEC-Q101 qualified. For automotive use, Diodes recommends contacting their applications team to evaluate qualification path or select AEC-Q101-rated alternatives like the ABS10Q series with identical DF-S footprint.
Does DF10S require a heatsink for 1.0A operation?
No external heatsink is required for 1.0A operation at TA ≤ +40°C with standard 5.0mm² copper land pads, as specified in the datasheet. However, thermal performance improves significantly with larger copper areas or internal layer connections-especially above +60°C ambient or under sustained surge conditions.
How does DF10S compare to fast recovery bridge rectifiers in EMI-sensitive designs?
DF10S has standard recovery (trr > 500ns), generating higher switching noise than fast recovery bridges (e.g., GBU8J, trr ≈ 250ns). In EMI-sensitive applications, use input LC filters and proper PCB layout-its 25pF junction capacitance per element helps limit high-frequency ringing, but it is not optimized for high-frequency SMPS front-ends.
