Product details
Overview
DL4006-13 from Diodes Incorporated is a glass passivated 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 at 1.0 A. It delivers high reliability with low leakage (5.0 µA at 25°C) and is used in AC/DC front-end rectification for industrial power supplies and LED drivers.
For engineers reviewing the DL4006-13 datasheet, DL4006-13 pinout, DL4006-13 application, or DL4006-13 equivalent, key selection criteria include VRRM derating at elevated ambient temperatures, thermal resistance (RJA = 50 K/W), junction capacitance (Cj = 15 pF at 4 V), and surge current capability (IFSM = 30 A, 8.3 ms half-sine).
Technical Context
This MELF-packaged rectifier operates as a single-phase, half-wave AC-to-DC converter under resistive or inductive loads at 60 Hz. Its glass passivation ensures stable performance across -55°C to +150°C operating range and supports UL 94V-0 flammability compliance.
The device exhibits a typical junction capacitance of 15 pF at 4 V reverse bias and shows forward voltage saturation near 1.1 V at rated DC current. Derating is required for capacitive loads (20% IO reduction) and elevated ambient temperatures per Fig. 1.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 800 V - Maximum repetitive reverse voltage before breakdown; defines safe AC input voltage handling in bridge or single-diode rectifiers. |
| IO @ TT=75°C | 1.0 A - Continuous DC output current limit when terminal temperature is held at 75°C; requires heatsinking or airflow above ~40°C ambient. |
| VF @ IF=1.0A | 1.1 V - Forward conduction loss at full load; contributes ~1.1 W conduction loss per diode in linear operation. |
| IFSM (8.3ms) | 30 A - Non-repetitive surge rating; withstands inrush currents during cold-start of switched-mode power supplies. |
| IR @ VR=800V, TA=25°C | 5.0 µA - Reverse leakage at rated blocking voltage; ensures minimal standby power loss in high-impedance hold-up stages. |
| RJA | 50 K/W - Junction-to-ambient thermal resistance in free air; determines temperature rise (ΔT = Pd × RJA) without PCB copper or heatsink. |
Pinout & Package
DL4006-13 uses a cylindrical MELF (Metal Electrode Leadless Face) package with axial polarity marking: cathode indicated by a single band. No discrete pins-device connects via end-cap solder terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unbanded end) | AC input / positive-side connection | Accepts incoming alternating waveform; must be rated for full RMS input voltage plus margin. |
| Cathode (banded end) | DC output / negative-side connection | Delivers rectified unidirectional current; polarity reversal causes catastrophic failure. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Enables stable reverse leakage and long-term reliability under humidity and thermal cycling stress. |
| UL 94V-0 plastic case | Meets flame-retardant safety requirements for enclosed industrial and lighting equipment. |
| Low VF (1.1 V @ 1A) | Reduces conduction losses in high-efficiency offline rectifiers where thermal budget is constrained. |
| MELF mechanical robustness | Withstands board flexure and vibration better than SOD-123 or DO-214 packages in harsh environments. |
Applications
| Industrial AC/DC Power Supplies | LED Driver Input Rectification |
|---|---|
Use Scenario: Single-phase rectification stage in 85–265 VAC input switch-mode power supplies for PLCs and motor controllers. IC Role / Device Role / Timing Role: Primary-side unidirectional current converter; blocks reverse AC half-cycles and delivers pulsating DC to bulk capacitor. Use Value: 800 V VRRM provides 2× margin over 265 VAC peak (375 V), ensuring robustness against line surges and transients. | Use Scenario: Input rectifier in constant-current LED drivers for street lighting and high-bay fixtures. IC Role / Device Role / Timing Role: Converts AC line to DC bus prior to buck or flyback regulation; operates continuously at partial load. Use Value: Low IR (5.0 µA) minimizes no-load power loss, supporting Energy Star and IEC 62384 standby efficiency requirements. |
| Capacitor-Input Filter Circuits | High-Reliability Signal Conditioning |
Use Scenario: Rectifier feeding bulk electrolytic capacitor in off-line SMPS with high crest factor. IC Role / Device Role / Timing Role: Conducts only during AC voltage peaks; subjected to high peak current pulses and thermal cycling. Use Value: 30 A IFSM rating handles repeated inrush into large capacitors without degradation over 100,000+ cycles. | Use Scenario: Precision rectification in analog signal path conditioning for sensor front-ends in test equipment. IC Role / Device Role / Timing Role: Half-wave detector in wide-temperature-range instrumentation requiring stable leakage behavior. Use Value: Specified IR up to +100°C (50 µA) enables predictable offset correction in DC-coupled measurement circuits. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MUR108 | Ultrafast recovery (trr = 75 ns vs. DL4006's unspecified but >500 ns); VF = 1.7 V @ 1A. | Better suited for high-frequency switching (e.g., PFC boost stages); higher conduction loss. | Select when EMI filtering or reduced switching noise is critical; avoid if thermal headroom is limited. |
| Vishay 1N4006GP-E3/54 | DO-41 through-hole package; identical VRRM (800 V), IO (1A), VF (1.1 V), and IR (5 µA). | Requires wave soldering or hand assembly; not compatible with automated SMT lines. | Choose for legacy repair, prototyping, or cost-sensitive through-hole designs where MELF placement is impractical. |
Compared with MUR108, DL4006-13 offers lower forward loss and SMT compatibility but slower recovery; versus 1N4006GP-E3/54, it provides identical electrical specs in a smaller, automated-assembly-ready MELF form factor with superior vibration resistance.

FAQ
Is DL4006-13 suitable for use in a bridge rectifier configuration?
Yes - DL4006-13 is commonly used in single-phase full-wave bridge configurations (e.g., four DL4006-13 devices). Its 800 V VRRM rating supports input voltages up to 265 VAC RMS, and its 30 A IFSM withstands surge currents typical in bridge topologies during cold start.
What is the maximum recommended PCB pad size for DL4006-13 in MELF layout?
Per Diodes Incorporated application guidance, use circular pads ≥2.8 mm diameter on both ends, with ≥0.3 mm solder mask clearance. Pad spacing should match the MELF body length (4.8–5.2 mm) to ensure coplanar termination and prevent tombstoning during reflow.
Does DL4006-13 require derating when mounted vertically?
No - mounting position does not affect thermal performance. The datasheet explicitly states "Mounting Position: Any." However, vertical orientation may reduce natural convection cooling; for continuous 1.0 A operation above 40°C ambient, forced airflow or thermal vias are advised regardless of orientation.
Can DL4006-13 replace DL4007 in a 1000 V design?
No - DL4006-13 has 800 V VRRM, while DL4007 specifies 1000 V. Substituting introduces insufficient voltage margin, increasing risk of avalanche breakdown during line transients or brownouts. Use DL4007 or a higher-rated alternative like VS-1N5408TR for 1000 V applications.
