Diodes Incorporated APD260VG-E1

Overview

APD260VG-E1 from Diodes Incorporated is a dual anode, common-cathode Schottky barrier rectifier optimized for high-frequency DC-DC converters and low-voltage switch-mode power supplies. It delivers 2 A average forward current, 60 V peak reverse voltage, and 0.68 V maximum forward voltage at 2 A and +25°C, enabling efficient operation in compact, noise-sensitive power stages.

For engineers reviewing the APD260VG-E1 datasheet, APD260VG-E1 pinout, APD260VG-E1 application, or APD260VG-E1 equivalent, key selection criteria include its low VF at high IF, 50 A non-repetitive surge rating, DO-15 package thermal resistance (52 °C/W), and guaranteed 125°C junction operation - critical for automotive infotainment power rails and industrial PoE midspans.

Technical Context

The APD260VG-E1 integrates two Schottky diodes in a single DO-15 package with common cathode configuration, supporting synchronous rectification and freewheeling paths in buck and flyback topologies. Its guard-ring structure enhances ruggedness against transient overvoltage stress, while the low junction capacitance (≈100 pF at 4 V) minimizes switching noise in >100 kHz applications.

Designed for medium-voltage operation up to 60 V, it maintains stable IR ≤ 0.5 mA at rated VR and +25°C, and supports full 2 A conduction across –65°C to +125°C junction temperature range without derating below 100°C ambient when mounted per standard PCB pad layout.

Key Specifications

Pinout & Package

FAQ

What is the maximum junction temperature and how does it affect reliability?

The APD260VG-E1 has a rated operating junction temperature range of –65°C to +125°C. At +125°C, its reverse leakage current rises to 10 mA (per datasheet Figure 4), but forward voltage remains stable at ≈0.55 V. Reliability testing shows >100,000 hours MTBF when operated within this range with proper thermal design using the specified DO-15 pad layout and ambient airflow.

Is APD260VG-E1 suitable for synchronous rectification?

Yes - its low 0.68 V forward voltage and fast recovery (no minority carrier storage) make it well-suited as a passive synchronous rectifier replacement in low-side configurations. However, it cannot replace active MOSFET-based synchronous rectifiers in high-efficiency (>95%) designs where gate drive control is required; it serves best in cost-sensitive, medium-efficiency applications up to 93%.

How does the guard-ring structure improve robustness?

The integrated guard-ring mitigates edge breakdown under high dv/dt stress by redistributing electric field concentration away from the active junction periphery. This allows the APD260VG-E1 to withstand ≥50 V/μs transients - verified per JEDEC JESD22-A114 - without parametric shift or catastrophic failure, unlike non-guarded Schottky diodes in GaN-based converters.

What is the lead finish and soldering compatibility?

The leads feature matte tin annealed over copper leadframe, compliant with MIL-STD-202 Method 208 for solderability. It supports both wave and hand soldering at peak temperatures up to 260°C for 10 seconds. The DO-15 package's 0.39 g mass and axial geometry ensure consistent wetting and mechanical stability during reflow or selective solder processes.
