Diodes Incorporated DL4002-13-F

Overview

DL4002-13-F from Diodes Incorporated is a glass passivated surface-mount silicon rectifier diode rated for 100 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 features low leakage (5.0 µA at 25 °C), 30 A non-repetitive surge capability, and MELF plastic package compliant with UL 94V-0.

For engineers reviewing the DL4002-13-F datasheet, DL4002-13-F pinout, DL4002-13-F application, or DL4002-13-F equivalent, key selection criteria include its 100 V blocking rating, thermal resistance (50 K/W), junction capacitance (15 pF), derating behavior above 75 °C, and suitability for compact AC/DC front-end and DC-DC input stage rectification in space-constrained industrial power supplies.

Technical Context

This device operates as a single-phase, half-wave rectifier under resistive or inductive loads at 60 Hz. Its glass passivation ensures stable junction integrity and low reverse leakage across -55 °C to +150 °C operating range.

The MELF package enables high power density with uniform thermal distribution; junction-to-ambient thermal resistance is 50 K/W, and typical junction capacitance is 15 pF at 4 V reverse bias and 1 MHz - critical for EMI-sensitive switching inputs.

Key Specifications

Pinout & Package

DL4002-13-F uses a cylindrical MELF (Metal Electrode Leadless Face) plastic package with axial cathode band marking. No discrete pins - terminals are solderable metallized ends conforming to MIL-STD-202, Method 208.

FAQ

What is the maximum allowable ambient temperature for continuous 1.0 A operation?

DL4002-13-F sustains 1.0 A average forward current only up to 75 °C terminal temperature (TT). Ambient temperature must be reduced per Fig. 1 derating curve - e.g., ~55 °C max ambient in still air with 50 K/W RJA and 1.1 W dissipation. Forced airflow or PCB copper area can extend usable ambient range.

Can DL4002-13-F replace DL4001-13-F in a design?

Yes, DL4002-13-F (100 V VRRM) is a direct upgrade from DL4001-13-F (50 V VRRM) with identical package, thermal specs, and forward characteristics. No layout change is needed, and it adds 100% reverse voltage margin - beneficial for designs targeting global mains input or transient-prone environments.

Is the MELF package compatible with standard reflow profiles?

Yes - DL4002-13-F's plastic MELF case is qualified for lead-free reflow per J-STD-020. Peak temperature must not exceed 260 °C for ≤10 seconds; preheat and soak zones should follow Diodes Inc. recommended profile DS16001 to avoid thermal shock cracking of the glass passivation layer.

Does DL4002-13-F meet automotive AEC-Q200 requirements?

No - DL4002-13-F is not AEC-Q200 qualified. While it operates from -55 °C to +150 °C, it lacks the stress testing, lot traceability, and failure analysis documentation required for automotive qualification. For AEC-Q200 applications, consider Diodes' AEC-Q200-certified rectifiers like the DFLS1100Q.
