Product details
Overview
DL4001-13-F from Diodes Incorporated is a glass passivated surface-mount silicon rectifier diode rated for 1.0A average forward current, 50V peak repetitive reverse voltage (VRRM), and 1.1V maximum forward voltage at 1.0A. It features low leakage (5.0µA at 25°C), MELF package construction, and UL 94V-0 flammability rating, used in AC/DC input stage rectification for compact power supplies and LED drivers.
For engineers reviewing the DL4001-13-F datasheet, DL4001-13-F pinout, DL4001-13-F application, or DL4001-13-F equivalent, key selection criteria include VRRM margin for line surge, thermal resistance (50K/W) for board-level derating, junction capacitance (15pF) in high-frequency switching contexts, and MELF mounting compatibility with automated placement systems.
Technical Context
This device operates as a single-phase, half-wave rectifier under resistive or inductive loads at 60Hz. Its glass passivation ensures stable reverse characteristics across -55°C to +150°C operating range and supports reliable operation in automotive and industrial environments where humidity and thermal cycling are concerns.
The MELF package enables high power density per unit volume and superior thermal dissipation compared to standard SOD-123 packages. Junction-to-ambient thermal resistance of 50K/W reflects its suitability for natural-convection-cooled designs without heatsinks when ambient temperature remains ≤75°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 50 V - Maximum non-repetitive reverse voltage before breakdown; sets minimum insulation margin for 24–48V AC input stages |
| IO @ TT=75°C | 1.0 A - Continuous DC output current capability with terminal temperature held at 75°C; defines usable load capacity in enclosed enclosures |
| VF @ IF=1.0A | 1.1 V - Forward conduction loss at rated current; contributes ~1.1W conduction loss per diode in linear rectifier configurations |
| IR @ VR=50V, 25°C | 5.0 µA - Reverse leakage current; critical for low-power standby circuits and high-impedance bias networks |
| Cj @ VR=4V, 1MHz | 15 pF - Junction capacitance affecting EMI filtering and high-frequency switching noise coupling |
| RJA | 50 K/W - Thermal resistance from junction to ambient air; determines required PCB copper area for thermal management |
Pinout & Package
DL4001-13-F uses a cylindrical MELF (Metal Electrode Leadless Face) package with axial polarity marking: cathode indicated by a single band. No discrete pins-terminals are solderable metallized ends conforming to MIL-STD-202, Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode end | Forward current entry point | Connected to AC input or transformer secondary; must withstand surge currents up to 30A (8.3ms) |
| Cathode band end | Forward current exit / reverse blocking node | Connected to bulk capacitor or load; reverse-biased during negative AC half-cycle; blocks up to 50V |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Enables stable IR < 5µA over lifetime and prevents moisture-induced parameter drift in humid environments |
| UL 94V-0 plastic body | Meets flame-retardant safety requirements for Class II power supplies and medical auxiliary circuits |
| MELF mechanical robustness | Withstands >20G vibration and thermal shock cycles typical in automotive engine bay and industrial motor control applications |
| Low VF at 1.0A | Reduces conduction losses by ~15% versus legacy 1N4001-class diodes, improving efficiency in low-voltage adapter designs |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4001G-TP | VRRM = 50V, VF = 1.1V, but in DO-41 through-hole package; RJA ≈ 65K/W | Requires wave-soldering or hand assembly; unsuitable for fully SMT lines | Select only if legacy through-hole assembly is mandated and board rework is acceptable |
| ES1J | VRRM = 600V, VF = 1.7V, SOD-123 package; faster recovery (trr < 35ns) | Over-specified reverse voltage; higher conduction loss reduces efficiency in 24V systems | Choose only when fast recovery or higher VRRM is required for transient protection in noisy AC lines |
Compared with 1N4001G-TP and ES1J, DL4001-13-F offers optimal balance of SMT compatibility, thermal performance (50K/W), and conduction efficiency (1.1V VF) for 24–48V AC/DC inputs where size, manufacturability, and thermal headroom are prioritized over ultra-fast recovery or extreme voltage margin.
FAQ
What is the maximum allowable ambient temperature for continuous 1.0A operation?
DL4001-13-F sustains 1.0A average forward current only when terminal temperature (TT) is maintained at 75°C. Based on RJA = 50K/W, this corresponds to a maximum ambient temperature of approximately 25°C with zero PCB copper thermal enhancement. Derating curves (Fig. 1) show usable current drops to ~0.6A at 60°C ambient with standard FR-4 layout.
Can DL4001-13-F be used in full-wave bridge configurations?
Yes - DL4001-13-F is a single diode and may be used in discrete full-wave bridge designs. Four units can construct a custom bridge rectifier. However, it lacks integrated bridge packaging or matched VF/Tj tracking; for production bridges, Diodes' DB107S or GBU6K are recommended alternatives with tighter parameter matching.
Is the MELF package compatible with standard pick-and-place equipment?
Yes - DL4001-13-F's MELF body meets IPC-7351B MELF-MA footprint standards. Its 4.8–5.2mm length and 2.4–2.6mm diameter are supported by major placement platforms (e.g., Fuji NXT, Yamaha YSM20) using vacuum nozzles designed for cylindrical components and verified tape-and-reel orientation (13-inch reel, EIA-481-2 compliance).
Does DL4001-13-F meet AEC-Q200 stress test requirements?
No - DL4001-13-F is not AEC-Q200 qualified. While its -55°C to +150°C operating range overlaps automotive requirements, it lacks qualification testing for temperature cycling, humidity bias, and mechanical shock per AEC-Q200 Rev D. For automotive-grade rectifiers, consider Diodes' AEC-Q200-qualified APx series (e.g., AP7125Q).
