Product details
Overview
DL4007-13-F from Diodes Incorporated is a glass passivated MELF surface-mount silicon rectifier diode rated for 1000 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 at 25°C) and is used in AC/DC input stage rectification for industrial power supplies and LED drivers.
For engineers reviewing the DL4007-13-F datasheet, DL4007-13-F pinout, DL4007-13-F application, or DL4007-13-F equivalent, key selection criteria include VRRM rating, thermal resistance (RJA = 50 K/W), junction capacitance (Cj = 15 pF @ 4 V), surge capability (IFSM = 30 A), and MELF package compatibility with automated reflow assembly.
Technical Context
This device operates as a single-phase, half-wave rectifier under 60 Hz resistive or inductive loads. Its glass passivation ensures stable reverse characteristics across -55°C to +150°C operating range and supports derated operation under capacitive loads (20% IO reduction).
The MELF package enables high power density per unit volume with uniform thermal distribution. Junction-to-ambient thermal resistance of 50 K/W allows sustained 1.0 A conduction at 75°C case temperature without forced cooling in standard PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1000 V - Supports rectification in 800 VAC line-derived systems with safety margin |
| IO @ TT=75°C | 1.0 A - Sustained DC output current capability with natural convection cooling |
| VF @ IF=1.0A | 1.1 V - Low conduction loss enabling >85% efficiency in low-power SMPS front-ends |
| IFSM (8.3ms) | 30 A - Withstands typical AC line surge events without failure |
| IR @ VR=1000V, 25°C | 5.0 µA - Ensures minimal standby power loss in high-impedance hold-up circuits |
| Cj @ VR=4V, 1MHz | 15 pF - Limits high-frequency switching noise coupling in EMI-sensitive designs |
Pinout & Package
DL4007-13-F 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 terminations.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked end) | Forward current entry | Connected to AC input phase or transformer secondary winding |
| Cathode (banded end) | Forward current exit / reverse blocking node | Feeds bulk capacitor or downstream converter stage; withstands 1000 V reverse bias |
Key Features

| Low RJA (50 K/W) | Permits 1.0 A operation on standard FR-4 without heatsinking or airflow |
Applications
| Industrial AC/DC Power Supplies | LED Driver Input Rectification |
|---|---|
Use Scenario: Single-phase rectification in 230 VAC-fed open-frame power supplies for factory automation controllers. IC Role / Device Role / Timing Role: Primary-side uncontrolled rectifier converting AC line to pulsating DC before bulk capacitor filtering. Use Value: 1000 V VRRM provides 2× safety margin over 230 VAC RMS, reducing risk of catastrophic failure during brownouts or surges. | Use Scenario: Bridgeless rectification in constant-current LED drivers for street lighting. IC Role / Device Role / Timing Role: Half-wave rectifier in low-cost, high-reliability driver topologies where size and leakage are critical. Use Value: 5.0 µA IR at 25°C minimizes no-load power consumption, extending driver lifetime in outdoor environments. |
| Capacitor-Input Filter Stages | Surge-Protected DC Feeds |
Use Scenario: First-stage rectification feeding 470 µF electrolytic bulk capacitor in medical auxiliary power modules. IC Role / Device Role / Timing Role: High-voltage rectifier subjected to repeated inrush current during cold start. Use Value: 30 A IFSM rating handles capacitor charging surges without degradation over 100,000 cycles. | Use Scenario: DC input protection in PoE-powered network switches exposed to lightning-induced transients. IC Role / Device Role / Timing Role: Reverse-polarity and overvoltage clamp in redundant DC feed paths. Use Value: MELF geometry and glass passivation maintain consistent breakdown behavior after repeated 1 kV transient exposure. |
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 MUR1100E | Ultrafast recovery (trr = 75 ns vs. DL4007's ~2 µs), VF = 1.7 V @ 1 A | Better suited for high-frequency flyback snubbers; higher VF increases conduction loss | Select when switching frequency exceeds 100 kHz and reverse recovery noise must be minimized |
| Vishay VS-1N4007-M3/54 | Same VRRM/IO ratings, DO-41 through-hole package, RJA ≈ 65 K/W | Requires wave soldering or hand assembly; lower thermal performance on same PCB area | Select only when legacy through-hole layout or manual repair constraints prohibit MELF placement |
Compared with MUR1100E and VS-1N4007-M3/54, DL4007-13-F offers optimal balance of surge robustness, low VF, and surface-mount scalability-making it preferred for cost-sensitive, high-volume industrial power supplies where thermal management is passive and switching frequencies remain below 50 kHz.

FAQ
What is the maximum allowable ambient temperature for continuous 1.0 A operation?
DL4007-13-F sustains 1.0 A average forward current only up to 75°C terminal temperature-not ambient temperature. Per Figure 1 in DS16001 Rev. D-2, ambient temperature must be ≤55°C with natural convection on standard FR-4 to maintain TT ≤75°C, assuming RJA = 50 K/W and no local heating sources.
Can DL4007-13-F replace 1N4007 in existing designs?
Yes, but with layout adaptation: DL4007-13-F is MELF surface-mount while 1N4007 is DO-41 through-hole. Electrical specs match closely (VRRM = 1000 V, IO = 1.0 A), though DL4007 has lower VF (1.1 V vs. 1.15 V typical) and tighter IR control (5.0 µA vs. 5.0 µA max). Reflow profile must follow Diodes Inc.'s MELF recommendations.
Is DL4007-13-F suitable for use in capacitive-input filter circuits?
Yes, but with 20% derating of IO per datasheet Note 1. In capacitive-input configurations, peak current stress increases significantly; DL4007-13-F's 30 A IFSM rating supports this, but average current must be limited to 0.8 A to ensure reliability and avoid overheating under worst-case inrush conditions.
Does DL4007-13-F meet RoHS and REACH requirements?
Yes-DL4007-13-F is RoHS 2011/65/EU compliant and REACH SVHC-free per Diodes Incorporated's material declarations (Pub. #AP02015). Halogen-free status is confirmed: chlorine <900 ppm, bromine <900 ppm, total halogens <1500 ppm, per IEC 61249-2-21.
