Product details
Overview
DF06S from Diodes Incorporated is a 1.0A surface-mount standard recovery bridge rectifier with 600V 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), designed for AC/DC front-end conversion in industrial power supplies and LED drivers.
For engineers reviewing the DF06S datasheet, DF06S pinout, DF06S application, or DF06S equivalent, key selection criteria include its 600V blocking rating, thermal resistance of 40°C/W, surface-mount DF-S package compatibility, and compliance with RoHS, halogen-free, and automotive-ready manufacturing standards.
Technical Context
The DF06S integrates four silicon diodes in a single-phase full-wave bridge configuration with internal common-cathode and common-anode nodes. Its standard recovery characteristic (non-fast, non-ultrafast) supports line-frequency rectification without significant switching loss concerns.
Thermal performance is defined by a junction-to-ambient thermal resistance of 40°C/W on a 5.0mm² PCB copper land, and derating begins above +40°C ambient per the output current curve. The device operates across –55°C to +150°C junction temperature range and sustains 10.4 A²s I²t fusing rating under 8.3ms half-sine surge conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Maximum peak repetitive reverse voltage; defines safe AC input voltage handling up to ~424V RMS. |
| IF(AV) | 1.0 A - Average forward rectified current at TA = +40°C; sets continuous DC output capability in linearly derated operation. |
| VF Max | 1.1 V @ 1.0A - Forward voltage per diode element; determines conduction loss (1.1W total bridge loss at full load). |
| IR Max | 10 µA @ 25°C - Reverse leakage per element; ensures low standby power loss in high-impedance hold-up stages. |
| IFSM | 50 A - Non-repetitive surge current (8.3ms); supports cold-start inrush tolerance in capacitive-input supplies. |
| RθJA | 40 °C/W - Junction-to-ambient thermal resistance on standard PCB; informs heatsinking requirements for sustained 1A operation. |
| CT | 25 pF @ 1MHz - Typical capacitance per diode; minimizes EMI contribution in low-frequency rectifier applications. |
Pinout & Package
Package: DF-S molded plastic package (UL 94V-0), dimensions 7.4–7.9 mm × 6.2–6.5 mm × 2.4–2.6 mm height, with tin-plated terminals and moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| ~AC1 | AC Input Terminal 1 | One leg of AC input; connects to transformer secondary or AC line input in full-wave bridge topology. |
| ~AC2 | AC Input Terminal 2 | Second leg of AC input; completes differential AC path into bridge; polarity not internally distinguished. |
| +DC | Positive DC Output | Anode of output leg; delivers rectified positive voltage to bulk capacitor or downstream regulator. |
| –DC | Negative DC Output / Common Return | Cathode of output leg; serves as circuit ground reference and return path for DC load current. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated die | Enhances long-term reliability and humidity resistance in unsealed industrial environments. |
| 50A surge rating | Withstands repeated cold-start surges without degradation, eliminating need for external NTC thermistors in many designs. |
| UL Recognized Component (E364304) | Reduces certification burden for end-equipment safety approvals including UL/CSA/EN 62368-1. |
| RoHS, halogen- and antimony-free | Meets global environmental compliance mandates (RoHS 3, JEDEC JS709E) without requiring material waivers. |
| DF-S surface-mount footprint | Enables automated assembly and compact layout; compatible with standard reflow profiles (J-STD-020 Level 1). |
Applications
| Industrial Power Supplies | LED Driver Front-End |
|---|---|
Use Scenario: AC/DC conversion stage in DIN-rail mounted 24V/48V power supplies for PLCs and sensors. IC Role / Device Role / Timing Role: Full-wave bridge rectifier converting 100–277V AC mains to pulsating DC prior to bulk capacitance and regulation. Use Value: 600V VRRM safely covers universal input range; 1.1V VF limits conduction loss to <1.2W at full load, reducing thermal stress on PCB. | Use Scenario: Input rectification in constant-current LED drivers for street lighting and high-bay fixtures. IC Role / Device Role / Timing Role: Primary rectifier delivering DC bus to buck or flyback controller ICs driving high-power LED strings. Use Value: 50A IFSM accommodates high inrush during hot-plug events; glass passivation prevents corrosion in outdoor-housed luminaires. |
| Appliance Control Boards | AC Motor Control Modules |
Use Scenario: Low-power auxiliary supply in washing machine or HVAC control boards. IC Role / Device Role / Timing Role: Provides isolated low-voltage DC for microcontroller, relay drivers, and sensor interfaces. Use Value: DF-S package enables compact board area usage; 40°C/W RθJA allows natural convection cooling without heatsink. | Use Scenario: Rectification for gate drive or logic supply in single-phase AC motor inverters. IC Role / Device Role / Timing Role: Generates stable DC rail for isolated gate drivers and MCU peripherals in variable-speed drives. Use Value: 10µA IR at 25°C minimizes standby leakage in always-on control circuits; UL recognition simplifies system-level safety testing. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU6K (ON Semiconductor) | Same 600V VRRM and 1.0A IF(AV), but GBU package (larger, through-hole); VF = 1.05V typical, RθJA = 30°C/W. | Requires through-hole assembly and larger PCB real estate; better thermal performance but incompatible with SMT-only lines. | Select when legacy through-hole design or higher thermal margin is prioritized over automation compatibility. |
| MB6S (Vishay) | Identical DF-S package, 600V rating, and 1.0A rating; VF = 1.1V max, IR = 5µA max at 25°C - slightly lower leakage. | Drop-in SMT replacement with identical footprint and solder profile; minor leakage advantage in ultra-low-power standby. | Prefer when minimizing reverse leakage is critical and same form factor is required. |
Compared with GBU6K and MB6S, the DF06S offers optimal balance of SMT manufacturability, UL recognition, and automotive-capable process control - making it preferred for new industrial and lighting designs where board space, certification efficiency, and supply chain continuity are prioritized.

FAQ
What is the maximum operating temperature for DF06S?
The DF06S has a specified junction and storage temperature range of –55°C to +150°C. Its thermal resistance is 40°C/W, so at 1.0A average current and 25°C ambient, junction temperature rises approximately 40°C - well within limit. Derating begins above +40°C ambient per the published curve.
Is DF06S suitable for automotive applications?
DF06S is manufactured in IATF 16949-certified facilities and supports PPAP documentation. While not AEC-Q101 qualified out-of-box, Diodes offers automotive-grade variants (e.g., DF06SA) with full qualification - contact Diodes or Aetrix for change-controlled automotive release options.
How does DF06S differ from fast recovery bridge rectifiers?
DF06S uses standard recovery diodes (typical trr > 500ns), optimized for 50/60Hz line-frequency rectification. Fast recovery versions (e.g., GBU6J) have trr < 150ns and lower capacitance but higher VF - DF06S trades switching speed for lower conduction loss and cost in non-PFC applications.
Can DF06S be used in capacitive-input filter configurations?
Yes, but with 20% current derating per datasheet guidance. In capacitive-input designs, peak currents increase significantly; DF06S's 50A IFSM rating provides margin, though thermal design must account for higher RMS current and associated losses in the bridge.
