Product details
Overview
DL4005-13-F from Diodes Incorporated is a glass passivated MELF surface-mount silicon rectifier diode rated for 600 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 with low leakage (5.0 µA IR at 25°C) and is used in AC/DC input stage rectification for industrial power supplies and LED drivers.
For engineers reviewing the DL4005-13-F datasheet, DL4005-13-F pinout, DL4005-13-F application, or DL4005-13-F equivalent, key selection criteria include its 600 V blocking capability, MELF package thermal resistance (RJA = 50 K/W), junction capacitance (Cj = 15 pF @ 4 V), surge rating (IFSM = 30 A), and UL 94V-0 flammability compliance.
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 performance across −55°C to +150°C operating range.
The MELF (Metal Electrode Leadless Face) construction provides uniform heat dissipation and mechanical robustness without leads, supporting automated placement and reflow soldering. Polarity is marked by a cathode band; terminals are solderable per MIL-STD-202, Method 208.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Maximum non-repetitive reverse voltage the diode blocks reliably in circuit |
| IO @ TT=75°C | 1.0 A - Continuous DC output current sustainable with proper heatsinking at terminal temp |
| VF @ IF=1.0A | 1.1 V - Forward conduction loss impacting efficiency and thermal rise in rectifier stage |
| IFSM (8.3ms) | 30 A - Surge withstand capability during cold-start or line transients |
| IR @ VR=600V, TA=25°C | 5.0 µA - Low leakage preserves blocking integrity in high-impedance bias networks |
| Cj @ VR=4V, 1MHz | 15 pF - Junction capacitance affecting high-frequency switching noise and EMI filtering design |
| RJA | 50 K/W - Thermal resistance from junction to ambient air, critical for passive cooling layout |
Pinout & Package
DL4005-13-F uses a two-terminal MELF (cylindrical) package with cathode band marking. No discrete pins-terminals are axial metal end caps; polarity must be oriented per band during PCB layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked end) | Forward current entry point | Connected to AC source or transformer secondary side in half-wave configuration |
| Cathode (band-marked end) | Forward current exit / reverse blocking node | Connected to output filter capacitor or load return; carries full reverse voltage when off |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Enables stable long-term operation and reduced parameter drift over temperature and time |
| UL 94V-0 plastic case | Meets flame-retardant safety requirements for enclosed industrial and lighting equipment |
| Low VF (1.1 V @ 1A) | Reduces conduction loss and thermal stress in compact, unventilated power supplies |
| MELF geometry | Provides symmetrical thermal path and high surface-area-to-volume ratio for natural convection cooling |
| 150°C max junction temperature | Supports operation in high-ambient environments such as LED streetlight housings or motor control enclosures |
Applications
| AC/DC Adapter Input Stage | LED Driver Bulk Rectification |
|---|---|
Use Scenario: Converts 120/230 VAC mains to pulsating DC before bulk capacitor smoothing in Class II isolated adapters. IC Role / Device Role / Timing Role: Primary-side rectifier diode in single-phase half-wave topology. Use Value: 600 V VRRM safely handles 230 VAC + 10% tolerance and line surges; 1.1 V VF limits self-heating in sealed plastic enclosures. | Use Scenario: Rectifies transformer-coupled AC output in constant-current LED drivers for outdoor signage. IC Role / Device Role / Timing Role: Output-stage rectifier delivering DC to current-regulating buck controller. Use Value: MELF package withstands thermal cycling in high-temp LED modules; 50 K/W RJA enables reliable operation without heatsink at ≤0.7 A load. |
| Industrial Sensor Power Supply | Small Appliance Motor Control |
Use Scenario: Provides isolated auxiliary power for 4–20 mA loop-powered sensors in factory automation systems. IC Role / Device Role / Timing Role: Half-wave rectifier feeding linear regulator IC (e.g., LM78L05). Use Value: Low IR (5 µA) prevents loading of high-impedance feedback paths; −55°C to +150°C rating supports wide ambient deployment. | Use Scenario: Rectifies AC from triac-dimmed supply to power logic and gate drive circuits in fan or pump controllers. IC Role / Device Role / Timing Role: Non-synchronous rectifier in low-cost universal motor interface. Use Value: 30 A IFSM tolerates repeated triac turn-on surges; UL 94V-0 case satisfies appliance safety certification requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4005G (ON Semiconductor) | Same VRRM (600 V), IO (1.0 A), VF (1.1 V), but DO-41 through-hole package | Requires wave soldering or hand assembly; unsuitable for fully SMT production lines | Select if legacy board reuse or manual repair is prioritized over automation |
| ES1J (Vishay) | Higher switching speed (trr ≈ 50 ns vs. DL4005's ~2 µs), lower Cj (10 pF), same VRRM/IO | Better suited for higher-frequency flyback snubbers or PFC pre-regulators where recovery loss matters | Choose when reducing EMI or improving light-load efficiency is critical |
Compared with 1N4005G, DL4005-13-F enables automated SMT placement and better thermal performance in confined spaces; versus ES1J, it trades faster recovery for lower cost and higher surge robustness in line-frequency rectification.

FAQ
What is the maximum allowable junction temperature for DL4005-13-F?
The absolute maximum junction temperature (Tj) is +150°C, as specified in the DS16001 datasheet. Operation above this limit risks irreversible degradation of the passivation layer and increased leakage. Derating curves in Figure 1 define safe IO limits based on ambient or terminal temperature.
Can DL4005-13-F be used in full-wave bridge configurations?
Yes - DL4005-13-F may be used as one leg in a discrete full-wave bridge (e.g., four units in standard configuration), provided each diode sees ≤600 V reverse voltage and total forward current remains within 1.0 A average per device. Layout must ensure matched thermal coupling to avoid current imbalance.
Is DL4005-13-F RoHS and REACH compliant?
Yes - DL4005-13-F meets RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, as confirmed in Diodes Incorporated's official compliance documentation (Declaration of Conformity DOC-0023 rev. H). Lead-free and halogen-free construction is standard.
How does the MELF package affect PCB layout compared to DO-41?
The MELF package requires axial orientation and land pattern matching its 4.8–5.2 mm length and 2.4–2.6 mm diameter. Unlike DO-41, it has no leads - so pad width must accommodate end-cap contact area, and placement must respect cathode band visibility for optical inspection. Reflow profile must avoid thermal shock due to glass body.
