Product details
Overview
DL4002-13 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 (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 DL4002-13 datasheet, DL4002-13 pinout, DL4002-13 application, or DL4002-13 equivalent, key selection criteria include its MELF package thermal resistance (RJA = 50 K/W), junction capacitance (Cj = 15 pF at 4 V), surge rating (IFSM = 30 A), and derating behavior across ambient temperature per Figure 1.
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 leakage over temperature (IR ≤ 50 µA at 100 °C).
The MELF (Metal Electrode Leadless Face) cylindrical package enables uniform heat dissipation and high-power density mounting. Junction-to-ambient thermal resistance of 50 K/W supports operation up to +150 °C junction temperature when properly mounted on thermally conductive PCB areas.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum non-repetitive reverse voltage the diode withstands without breakdown during transient conditions. |
| IO @ TT=75°C | 1.0 A - Continuous average forward current sustainable with terminal temperature held at 75 °C. |
| VF @ IF=1.0A | 1.1 V - Forward conduction loss at rated DC load, directly impacting efficiency and thermal design. |
| IFSM (8.3 ms) | 30 A - Peak non-repetitive surge current capability, critical for handling inrush or line transients. |
| IR @ VR=100V, 25°C | 5.0 µA - Reverse leakage current defining off-state power loss and signal integrity in high-impedance circuits. |
| Cj @ VR=4V, 1MHz | 15 pF - Junction capacitance affecting high-frequency switching noise and EMI filter interaction. |
Pinout & Package
DL4002-13 uses a two-terminal MELF (DO-213AA) package with axial polarity marking: cathode indicated by a single band near one end. No discrete pins-terminals are solderable metallized ends conforming to MIL-STD-202, Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to AC source or transformer secondary; must handle full surge and RMS current. |
| Cathode | Forward current exit / reverse blocking node | Marked with band; connects to output capacitor or load return; sustains full VRRM during off-cycle. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Enables stable IR < 50 µA up to 100 °C and long-term reliability in humid or contaminated environments. |
| UL 94V-0 plastic case | Meets flammability safety requirements for enclosed industrial and lighting equipment. |
| MELF package geometry | Provides symmetrical thermal path and mechanical robustness for reflow and vibration-prone applications. |
| Low VF (1.1 V @ 1A) | Reduces conduction loss by ~15% vs. standard 1N400x series, lowering heatsink demand in compact designs. |
Applications
| AC/DC Adapter Input Stage | LED Driver Bulk Rectification |
|---|---|
Use Scenario: 5–24 VAC input converted to DC for wall adapters powering consumer electronics. IC Role / Device Role / Timing Role: Primary rectifier converting AC line to unregulated DC bus prior to regulation. Use Value: Low VF minimizes self-heating at 1 A load; MELF form factor allows dense layout in space-constrained enclosures. | Use Scenario: Rectifying 12–36 VAC transformer output feeding constant-current LED modules. IC Role / Device Role / Timing Role: High-reliability bridge or half-wave rectifier sustaining continuous operation at elevated ambient temperatures. Use Value: 150 °C max junction rating and low IR ensure stable performance in sealed LED housings with limited airflow. |
| Industrial Control Power Supply | Surge-Tolerant Sensor Interface |
Use Scenario: 24 VAC control circuitry powering PLC I/O modules in factory automation panels. IC Role / Device Role / Timing Role: Input-stage rectifier providing isolated DC bias for optocouplers and logic-level circuitry. Use Value: 30 A IFSM withstands repeated contactor switching transients without degradation. | Use Scenario: Signal conditioning front-end for analog sensors exposed to 60 Hz mains-coupled noise. IC Role / Device Role / Timing Role: Clamp/rectify protection element limiting reverse voltage on downstream amplifiers. Use Value: Tight Cj = 15 pF minimizes capacitive coupling of high-frequency interference into sensitive analog paths. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4002-T | Same VRRM (100 V) and IO (1.0 A), but DO-41 through-hole package and higher VF (1.2 V typical). | Requires PCB through-hole mounting and offers lower thermal performance (RJA > 70 K/W). | Choose only if legacy board compatibility or manual assembly is required. |
| ES1J-E3/54 | Higher VF (1.7 V min), faster recovery (trr < 35 ns), and SMA package; rated for 600 V VRRM. | Designed for switching-mode topologies, not line-frequency rectification. | Not recommended for 60 Hz half-wave use due to excessive conduction loss and unnecessary speed. |
Compared with 1N4002-T and ES1J-E3/54, DL4002-13 provides superior thermal management in SMT layouts and optimized VF for linear rectification-making it preferred for modern, compact, and thermally constrained AC/DC front-ends.

FAQ
What is the maximum allowable junction temperature for DL4002-13?
The absolute maximum junction temperature is +150 °C, as specified in the DS16001 datasheet. Operation above this limit risks irreversible degradation of the passivated junction. Derating curves (Figure 1) define safe IO limits based on ambient and mounting conditions-e.g., IO drops to ~0.6 A at TA = 100 °C with standard PCB copper area.
Can DL4002-13 be used in full-wave bridge configurations?
Yes-DL4002-13 is commonly used as one leg in discrete full-wave bridge rectifiers. Its 100 V VRRM and 30 A IFSM support standard 12–48 VAC inputs. However, each diode sees double the PIV in center-tapped configurations, so verify reverse voltage stress does not exceed 100 V under worst-case line and load conditions.
Is DL4002-13 RoHS compliant and halogen-free?
Yes-DL4002-13 meets RoHS Directive 2011/65/EU and is halogen-free per Diodes Incorporated's material declarations. The MELF package uses UL 94V-0 rated plastic, and all metallization complies with JEDEC J-STD-609A Class 1 for moisture sensitivity (MSL 1, unlimited floor life).
How does DL4002-13 compare to DL4001 in terms of forward voltage and leakage?
DL4002-13 and DL4001 share identical VF (1.1 V @ 1.0 A) and IR (5.0 µA @ 25 °C), differing only in VRRM: DL4001 is rated for 50 V, while DL4002 is rated for 100 V. Both use the same die process and MELF package, so thermal and dynamic characteristics are functionally interchangeable where voltage margin permits.
