Product details
Overview
DL4006-13-F from Diodes Incorporated is a glass passivated MELF surface-mount silicon rectifier diode rated for 800 V peak repetitive reverse voltage (VRRM), 1.0 A average forward rectified current (IO) at 75°C terminal temperature, and 1.1 V maximum forward voltage (VF) at 1.0 A. It delivers high reliability, low leakage, and low forward voltage drop in a compact MELF package, used in AC/DC input stage rectification for industrial power supplies and LED drivers.
For engineers reviewing the DL4006-13-F datasheet, DL4006-13-F pinout, DL4006-13-F application, or DL4006-13-F equivalent, key selection criteria include VRRM rating, thermal resistance (RJA = 50 K/W), junction capacitance (Cj = 15 pF @ 4 V), surge current capability (IFSM = 30 A), and MELF mechanical dimensions (A: 4.80–5.20 mm, B: 2.40–2.60 mm).
Technical Context
This device operates as a single-phase, half-wave rectifier under 60 Hz resistive or inductive loads, with derating required for capacitive loads (−20% IO). Its glass passivation ensures stable junction characteristics and low IR across −55°C to +150°C operating range.
The MELF package enables high power density and reliable solder joint formation on PCBs, while its cathode band polarity marking and UL 94V-0 compliant plastic case support safety-critical surface-mount applications requiring long-term thermal stability and moisture resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 800 V - Maximum non-repetitive reverse voltage the diode blocks without breakdown; defines usable AC input voltage headroom in bridge or single-diode rectifiers. |
| IO @ TT=75°C | 1.0 A - Continuous DC output current capability when terminal temperature is maintained at 75°C; sets minimum heatsinking requirement. |
| VF @ IF=1.0A | 1.1 V - Forward conduction loss at rated current; directly impacts power dissipation (1.1 W typical) and thermal design. |
| IFSM (8.3ms) | 30 A - Peak non-repetitive surge current tolerance; determines immunity to line transients and inrush events. |
| RJA | 50 K/W - Junction-to-ambient thermal resistance; used to calculate temperature rise (ΔT = Pd × RJA) without heatsink. |
| Cj @ VR=4V | 15 pF - Junction capacitance at 4 V reverse bias; affects high-frequency switching noise and EMI in fast-switching circuits. |
Pinout & Package
DL4006-13-F uses a cylindrical MELF (Metal Electrode Leadless Face) package with axial polarity marking: cathode indicated by a single dark band. No discrete pins-terminals are formed by metallized end caps; soldered radially onto PCB pads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked end) | Forward current entry point | Connected to AC source or transformer secondary during positive half-cycle conduction. |
| Cathode (banded end) | Forward current exit point | Connected to output filter capacitor or load return; defines DC output polarity. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Enables stable reverse leakage (<5.0 µA @ 25°C, <50 µA @ 100°C) and long-term reliability in humid or thermally cycling environments. |
| UL 94V-0 plastic case | Meets flammability safety standard for enclosed power electronics, supporting compliance in industrial and lighting equipment. |
| MELF mechanical form factor | Provides superior thermal performance vs. SOD-123/SMA packages due to larger surface area and symmetric heat path to PCB copper. |
| Low VF (1.1 V @ 1.0 A) | Reduces conduction losses by ~15% compared to standard 1N400x series, improving efficiency in low-cost linear and flyback supplies. |
Applications
| AC/DC Adapter Input Rectification | LED Driver Bridge Rectification |
|---|---|
Use Scenario: Single-diode rectification in universal-input (90–264 VAC) wall adapters powering consumer electronics. IC Role / Device Role / Timing Role: High-voltage rectifier converting AC mains to pulsating DC prior to smoothing capacitor and regulator. Use Value: 800 V VRRM provides 2× safety margin over 264 VAC peak (373 V), ensuring robust operation during brownouts and surges. | Use Scenario: Half-wave rectification in low-cost constant-current LED driver modules for street lighting. IC Role / Device Role / Timing Role: Primary rectifier in transformerless topology, handling 50/60 Hz line frequency with minimal conduction loss. Use Value: 1.1 V VF minimizes self-heating at 1.0 A, enabling compact layout without forced air cooling in sealed enclosures. |
| Industrial Control Power Supply | Surge-Protected Sensor Interface |
Use Scenario: Input stage of 24 VDC industrial PLC power supply accepting 120/240 VAC input. IC Role / Device Role / Timing Role: Front-end rectifier subjected to frequent line transients and thermal cycling in factory environments. Use Value: 30 A IFSM withstands repeated 100 A/1 µs surge events per IEC 61000-4-5 Level 3, reducing need for external TVS clamping. | Use Scenario: Reverse-polarity protection and transient suppression in 4–20 mA sensor loop interfaces. IC Role / Device Role / Timing Role: Series-connected blocking diode preventing damage from accidental reverse wiring or induced lightning surges. Use Value: Low 50 K/W RJA allows direct PCB mounting without heatsink, saving board space while maintaining <125°C junction temp under full load. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1R08 | TO-277A package (SMD), VF = 1.15 V @ 1.0 A, VRRM = 800 V, RJA = 65 K/W | Higher thermal resistance requires larger copper pour; less suitable for ultra-compact layouts | Preferred where higher surge rating (IFSM = 50 A) and AEC-Q101 qualification are needed. |
| ES1J | SMA package, VF = 1.7 V @ 1.0 A, VRRM = 600 V, IO = 1.0 A, RJA = 70 K/W | Lower VRRM limits use to ≤277 VAC systems; higher VF increases conduction loss by 55% | Cost-optimized alternative only for 120 VAC-only designs with relaxed efficiency targets. |
Compared with STTH1R08 and ES1J, DL4006-13-F offers the lowest thermal resistance (50 K/W) and best VF (1.1 V) in an industry-standard MELF footprint-enabling higher power density and cooler operation in space-constrained 240 VAC input stages.

FAQ
What is the maximum allowable ambient temperature for continuous 1.0 A operation?
At 1.0 A DC load, DL4006-13-F requires terminal temperature (TT) ≤75°C. With RJA = 50 K/W and Pd ≈ 1.1 W, maximum ambient temperature is 75°C − (1.1 × 50) = 20°C without heatsinking. Derating curves (Fig. 1) show 0.6 A usable at 70°C ambient on standard FR-4 PCB.
Can DL4006-13-F replace DL4007 in a 1000 V design?
No-DL4006-13-F has VRRM = 800 V, while DL4007 is rated for 1000 V. Substituting it in a 1000 V system risks reverse breakdown during transients or voltage spikes. The 200 V margin reduction violates standard 20% safety rule for AC line rectifiers.
Is the MELF package compatible with standard reflow profiles?
Yes-DL4006-13-F meets JEDEC J-STD-020 moisture sensitivity level 1 and is qualified for lead-free reflow up to 260°C peak. Its glass passivation and UL 94V-0 body withstand thermal shock; recommended profile follows IPC-7530 guidelines with ramp rates ≤3°C/s and time above 217°C ≤60 seconds.
Does DL4006-13-F have AEC-Q200 qualification?
No-DL4006-13-F is not AEC-Q200 qualified. Diodes Incorporated offers automotive-grade alternatives (e.g., DFLS1600Q) with AEC-Q200 certification, but DL4006-13-F is intended for industrial and commercial applications per its datasheet scope and test conditions.
