Diodes Incorporated DL4005-13

Overview

DL4005-13 from Diodes Incorporated is a glass passivated 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 features low leakage (5.0 µA at 25°C), 30 A non-repetitive surge capability (8.3 ms half-sine), and MELF plastic package compliant with UL 94V-0.

For engineers reviewing the DL4005-13 datasheet, DL4005-13 pinout, DL4005-13 application, or DL4005-13 equivalent, key selection criteria include its 600 V blocking rating, thermal resistance (50 K/W), junction capacitance (15 pF at 4 V), MELF mechanical dimensions (A: 4.8–5.2 mm, B: 2.4–2.6 mm), and derating behavior under capacitive loads.

Technical Context

This device operates as a unidirectional power rectifier in AC-to-DC conversion stages. Its glass passivation ensures stable junction integrity under thermal cycling and humidity exposure, while the MELF package enables high-power density mounting on PCBs without leads.

Designed for single-phase, half-wave 60 Hz operation with resistive or inductive loads, it requires 20% forward current derating when used with capacitive loads. Junction-to-ambient thermal resistance of 50 K/W defines its passive cooling limits in open-air or minimal heatsink configurations.

Key Specifications

Pinout & Package

DL4005-13 uses a cylindrical MELF (Metal Electrode Leadless Face) plastic package with axial polarity marking: cathode indicated by a band. No discrete pins-terminals are solderable end caps conforming to MIL-STD-202, Method 208.

FAQ

What is the maximum allowable ambient temperature for DL4005-13 at full 1.0 A load?

At 1.0 A average forward current, DL4005-13 must be operated below 75°C ambient temperature when mounted on standard FR-4 PCB with no forced airflow, per Figure 1 derating curve. Above this, current must be reduced linearly to maintain junction temperature ≤150°C. Thermal relief pads and copper pour significantly extend usable ambient range.

Can DL4005-13 replace DL4007 in a 1000 V design?

No-DL4005-13 has 600 V VRRM, while DL4007 is rated for 1000 V. Substituting it in a 1000 V circuit risks catastrophic reverse breakdown during line surges or transients. The DL4005-13 is only suitable where peak reverse voltage remains ≤600 V, including safety margins per IEC 61000-4-5.

Is DL4005-13 suitable for use in a capacitive-input filter?

Yes, but with mandatory 20% forward current derating per datasheet Note 1. At 1.0 A rated IO, maximum continuous current drops to 0.8 A in capacitive-input configurations due to higher peak currents and increased thermal stress on the junction.

Does DL4005-13 have a specified reverse recovery time (trr)?

No-the DL4005-13 is a standard recovery rectifier with no trr specification in its datasheet. It is not optimized for high-frequency switching; typical recovery is >2 µs. For <500 ns trr, consider fast recovery alternatives like ES1J or UF4005, which trade off higher VF for speed.
