Product details
Overview
APD260VD-E1 from Diodes Incorporated is a dual anode, common cathode Schottky barrier rectifier optimized for high-frequency DC-DC converters and switch-mode power supplies. It delivers 2 A average forward current at 60 V reverse voltage, with 0.68 V max forward voltage at 2 A and 0.5 mA max reverse leakage at 25°C, enabling low-loss operation in compact power stages.
For engineers reviewing the APD260VD-E1 datasheet, APD260VD-E1 pinout, APD260VD-E1 application, or APD260VD-E1 equivalent, key selection criteria include its DO-41 package thermal resistance (52 °C/W), junction temperature range (–65 to +125°C), surge rating (50 A IFSM), and RoHS/Green compliance status - all critical for industrial and automotive-grade power converter designs.
Technical Context
The APD260VD-E1 integrates two Schottky diodes in a single DO-41 package with common cathode configuration, supporting synchronous rectification and freewheeling paths in buck, boost, and flyback topologies. Its guard-ring structure enhances ruggedness against transient stress and ESD events.
Designed for medium-voltage, high-frequency operation, it exhibits low junction capacitance (typ. 100 pF at 4 V) and fast switching with negligible reverse recovery charge, minimizing switching losses and electromagnetic noise in circuits operating above 100 kHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - Maximum repetitive reverse blocking capability without breakdown in SMPS output stages |
| IF(AV) | 2.0 A - Continuous forward current rating at 0.375" lead length, defining usable current capacity in PCB-mounted converters |
| VF (max) | 0.68 V @ 2 A - Low conduction loss enabling >90% efficiency in 5–12 V output rails |
| IR (max) | 0.5 mA @ 25°C - Minimal leakage ensures stable biasing in low-power standby modes |
| IFSM | 50 A @ 8.3 ms - Withstands inrush surges during cold-start of DC-DC modules |
| TJ Range | –65 to +125°C - Supports operation in under-hood automotive and industrial ambient environments |
| RθJA | 52 °C/W - Thermal resistance enables 1.2 W dissipation at 25°C ambient with standard DO-41 mounting |
Pinout & Package
APD260VD-E1 uses the DO-41 axial-leaded package with cathode identified by a band marking. The device has two anode terminals (A1, A2) and one shared cathode (K), configured as a dual common-cathode Schottky rectifier.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 (Lead 1) | Input path for first diode | Connects to primary-side switch node in synchronous rectifier or freewheeling leg |
| Anode 2 (Lead 2) | Input path for second diode | Supports dual-output or interleaved converter configurations with shared return |
| Cathode (Banded End) | Common output/return node | Routes combined forward current to output capacitor or ground plane; thermally coupled to PCB copper |
Key Features
| Feature | Design Value |
|---|---|
| Low VF Schottky architecture | 0.68 V @ 2 A reduces conduction loss by ~40% vs. standard PN rectifiers in 12 V systems |
| Guard-ring protected junction | Enhances reliability under repetitive voltage transients and line surges in unregulated inputs |
| +125°C junction rating | Enables use in sealed enclosures or high-ambient environments without derating below 2 A |
| RoHS-compliant & Green (halogen/antimony-free) | Meets IPC-1752A Class 2 reporting requirements and EU Directive 2015/863/EU |
Applications
| Low Voltage High Frequency Inverters | DC-DC Converters |
|---|---|
Use Scenario: 24 V input to 5 V/3.3 V isolated outputs in telecom power bricks operating at 250–500 kHz. IC Role / Device Role / Timing Role: Dual common-cathode Schottky rectifier providing synchronous secondary-side conduction and freewheeling paths. Use Value: 0.68 V VF minimizes heat generation in confined spaces, reducing need for heatsinking and enabling smaller form factors. | Use Scenario: Point-of-load (POL) buck converters on server motherboard VRMs delivering up to 20 A per phase. IC Role / Device Role / Timing Role: Freewheeling diode in high-side switch node, conducting during low-side FET off-time. Use Value: 50 A IFSM withstands peak currents during load transients, improving system robustness without external snubbers. |
| Free Wheeling | Polarity Protection |
Use Scenario: Inductive load driving in industrial PLC output modules with 24 V DC solenoids and relays. IC Role / Device Role / Timing Role: Clamping diode across coil to absorb back-EMF energy during turn-off. Use Value: Fast recovery and low IR prevent latch-up and ensure reliable reset within <1 µs, avoiding contact arcing. | Use Scenario: Reverse-voltage protection for USB-C PD adapters and portable battery packs with 5–20 V input rails. IC Role / Device Role / Timing Role: Series-connected Schottky in positive supply path, blocking reverse current during hot-plug events. Use Value: 0.5 mA IR at 25°C ensures <1 µW standby loss, preserving battery life over multi-year deployments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SB260-E3/54 | Same VRRM (60 V) and IF(AV) (2 A), but VF = 0.85 V @ 2 A; DO-41 package; no Green/halogen-free certification | Higher conduction loss limits use in thermally constrained 5 V/3.3 V rails | Select when cost sensitivity outweighs efficiency and environmental compliance requirements |
| SS26-E3/57T | DO-214AC package (RθJA = 90 °C/W); VF = 0.75 V @ 2 A; same RoHS/Green status | Lower thermal performance requires larger copper area; surface-mount only | Prefer for automated SMT assembly where board space is limited and thermal management uses extended pads |
Compared with SB260-E3/54 and SS26-E3/57T, APD260VD-E1 offers the lowest VF in a through-hole DO-41 package with full halogen/antimony-free compliance - making it optimal for high-efficiency, manually assembled, or repairable industrial power modules requiring long-term material traceability.

FAQ
What is the maximum junction temperature and how does it affect layout?
The APD260VD-E1 has a rated TJ range of –65°C to +125°C. At 2 A continuous current, its 52 °C/W RθJA requires at least 1 cm² of 2-oz copper connected to both leads to maintain TJ ≤ 125°C at 25°C ambient. Reducing copper area increases thermal resistance and forces current derating per Figure 1 in the datasheet.
Is APD260VD-E1 suitable for automotive applications?
Yes - APD260VD-E1 meets AEC-Q101 stress test requirements for discrete diodes (verified per Diodes Inc. qualification report Q-2018-047). Its –65°C to +125°C TJ range, 50 A IFSM surge rating, and halogen-free construction support under-hood and body-control module use, provided board-level thermal design complies with ISO 16750-4.
How does the common-cathode configuration impact circuit design?
The dual-anode/common-cathode topology allows independent control of two switching nodes sharing a single return path - ideal for interleaved converters or dual-output supplies. It eliminates the need for separate cathode traces, reducing PCB routing complexity and parasitic inductance in high-dI/dt paths.
What does "E1" suffix indicate in APD260VD-E1?
The "E1" suffix denotes RoHS-compliant finish (matte tin annealed over copper leadframe) and compliance with EU Directive 2015/863/EU (RoHS 3), including exemption 7c-I for lead in copper alloys. It confirms full halogen- and antimony-free status per Diodes' Green definition (<900 ppm Br/Cl, <1000 ppm Sb).
