Product details
Overview
DL4007-13 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 30 A non-repetitive peak forward surge current (IFSM). It delivers low forward voltage drop (1.1 V at 1.0 A) and low leakage (5.0 µA at 25°C), suited for high-reliability AC/DC front-end rectification in industrial power supplies.
For engineers reviewing the DL4007-13 datasheet, DL4007-13 pinout, DL4007-13 application, or DL4007-13 equivalent, key selection criteria include its 1000 V blocking capability, MELF package thermal resistance (50 K/W), junction capacitance (15 pF at 4 V), derating behavior above 75°C, and compatibility with automated SMT placement on FR-4 PCBs.
Technical Context
This device operates as a single-junction, planar-diffused, glass-passivated silicon rectifier optimized for high-voltage, medium-current switching applications. Its MELF (Metal Electrode Leadless Face) cylindrical package enables uniform heat dissipation and high reliability under thermal cycling, with cathode band polarity marking and UL 94V-0 compliant plastic encapsulation.
The diode exhibits a typical junction capacitance of 15 pF at 4 V reverse bias and 1.0 MHz, supporting stable performance in line-frequency rectification where capacitive loading is minimal. Forward conduction follows standard exponential I–V characteristics, with VF tightly specified at 1.1 V under 1.0 A DC load at 25°C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1000 V - supports input rectification from 707 V RMS AC sources (e.g., 3-phase 400 VAC systems with boost) |
| IO @ TT = 75°C | 1.0 A - maximum continuous DC output current with heatsink-free operation up to 75°C terminal temp |
| VF @ IF = 1.0 A | 1.1 V - low conduction loss yields ~1.1 W power dissipation at full rated current |
| IFSM (8.3 ms) | 30 A - withstands brief inrush surges common during AC mains turn-on or capacitor charging |
| IR @ VR = 1000 V | 50 µA @ 100°C - ensures minimal standby leakage in high-impedance hold-up circuits |
| RJA | 50 K/W - defines thermal rise from junction to ambient air without heatsink; limits max power to 2.0 W at ΔT = 100 K |
| Cj @ VR = 4 V | 15 pF - low capacitance minimizes EMI generation and switching losses in low-frequency rectifiers |
Pinout & Package
MELF (Metal Electrode Leadless Face) cylindrical package with axial symmetry; no discrete pins-cathode identified by a single black band near one end; anode and cathode terminals are metallized end caps solderable per MIL-STD-202, Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode End Cap | Forward current entry point | Connected to AC input phase or transformer secondary; must tolerate full surge current and thermal stress |
| Cathode End Cap (banded) | Forward current exit / reverse blocking node | Connected to bulk capacitor positive rail; reverse voltage rating applies across this terminal and anode |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Enables stable long-term reverse leakage performance and resistance to humidity-induced degradation |
| UL 94V-0 plastic encapsulation | Meets flammability safety requirements for enclosed industrial and medical power equipment |
| 1.0 A IO with MELF package | Delivers higher current density than SMA/SOD-123 equivalents while maintaining compact footprint |
| Low VF (1.1 V) | Reduces conduction loss by ~15% versus comparable 1000 V rectifiers with VF ≥ 1.3 V |
| High IFSM (30 A) | Supports robust startup in offline SMPS with large input X-capacitors without requiring external NTC thermistors |
Applications
| Industrial AC/DC Power Supply | LED Driver Input Stage |
|---|---|
Use Scenario: Rectifying 230 VAC or 400 VAC three-phase input before PFC stage in DIN-rail mounted power supplies. IC Role / Device Role / Timing Role: Primary high-voltage rectifier in bridge configuration or single-phase half-wave clamp. Use Value: 1000 V VRRM margin accommodates line transients up to 1.5× nominal voltage without breakdown. | Use Scenario: Off-line LED driver with passive PFC, converting 120/230 VAC to high-voltage DC bus. IC Role / Device Role / Timing Role: Input rectifier feeding bulk capacitor; operates at 50/60 Hz with minimal switching loss. Use Value: Low 1.1 V VF reduces thermal stress on board-level layout and extends electrolytic capacitor life. |

Use Scenario: Isolated auxiliary power supply in Class II medical devices requiring reinforced insulation. IC Role / Device Role / Timing Role: Secondary-side rectifier in flyback-derived bias supply, handling 250–400 VDC input.

IC Role / Device Role / Timing Role: Medium-voltage DC link rectifier feeding isolated DC/DC converter input. Use Value: MELF mechanical robustness resists vibration-induced failure in industrial motor control cabinets. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1R06S | TO-277 package (SMD), 600 V VRRM, VF = 1.15 V @ 1 A, RJA = 45 K/W | Limited to ≤600 V AC inputs; lower surge rating (25 A) | Select when space-constrained PCBs require flat-profile SMD mounting and 600 V rating suffices |
| ES1J-M3/5AT | SMA package, 600 V VRRM, VF = 1.7 V @ 1 A, IO = 1 A @ 110°C | Higher VF increases conduction loss; smaller thermal mass limits surge handling | Prefer for cost-sensitive consumer-grade designs where 600 V margin and higher VF are acceptable |
Compared with STTH1R06S and ES1J-M3/5AT, DL4007-13 provides 400–600 V higher blocking voltage and superior surge immunity (30 A vs. 25/18 A), making it uniquely suitable for industrial 400 VAC+ rectification where transient overvoltage resilience is critical.

FAQ
What is the maximum allowable ambient temperature for DL4007-13 at full 1.0 A load?
At 1.0 A DC forward current, DL4007-13 must be operated with terminal temperature (TT) ≤ 75°C. With RJA = 50 K/W, the maximum ambient temperature is approximately 50°C if no heatsinking is used-derating curves in DS16001 show linear reduction to zero current at 150°C ambient.
Can DL4007-13 replace DL4006 in an existing design?
Yes-DL4007-13 is a direct upgrade from DL4006 (800 V VRRM) with identical MELF package, pinout, and thermal characteristics. The 200 V higher VRRM improves transient margin but does not affect forward conduction or surge rating, which remain unchanged.
Is DL4007-13 suitable for use in a capacitive-input filter configuration?
No-datasheet Note 1 explicitly states that for capacitive loads, forward current must be derated by 20%. At 1.0 A rated IO, this limits usable current to 0.8 A in such configurations to prevent overheating due to increased peak current stress.
Does DL4007-13 meet RoHS and REACH compliance requirements?
Yes-DL4007-13 is RoHS 2011/65/EU and REACH SVHC-compliant, as confirmed in Diodes Incorporated's official product change notices and material declarations published on www.diodes.com.
