Product details
Overview
APD240VG-E1 from Diodes Incorporated is a dual Schottky barrier rectifier in DO-15 package, rated for 40 V repetitive peak reverse voltage, 2 A average forward current, and 0.5 V maximum forward voltage at 2 A and +25°C. It delivers low switching losses and low noise in high-frequency DC-DC converters and polarity protection circuits.
For engineers reviewing the APD240VG-E1 datasheet, APD240VG-E1 pinout, APD240VG-E1 application, or APD240VG-E1 equivalent, key selection factors include its 0.5 V VF at 2 A, 50 A non-repetitive surge rating, +125°C junction temperature, guard-ring stress protection, and RoHS-compliant lead-free DO-15 packaging.
Technical Context
The APD240VG-E1 integrates two independent Schottky diodes in a single DO-15 package, sharing a common cathode configuration as confirmed by top-view marking and pin assignment diagrams. Its low VF and fast recovery enable efficient operation in medium-voltage, high-frequency power conversion stages.
Thermal resistance is 52°C/W (junction-to-ambient, mounted per recommended pad layout), and it sustains 50 A IFSM for 8.3 ms half-sine surges. Reverse leakage remains ≤0.5 mA at 40 V and +25°C, rising to ≤10 mA at +100°C per datasheet electrical characteristics.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 40 V - Maximum repetitive reverse blocking capability without breakdown |
| IF(AV) | 2.0 A - Continuous average forward current rating at TA = +25°C with 0.375" lead length |
| VF (MAX) | 0.5 V @ 2 A, +25°C - Low conduction loss enabling high-efficiency rectification |
| IR (MAX) | 0.5 mA @ 40 V, +25°C - Minimal leakage preserving efficiency in standby and light-load conditions |
| IFSM | 50 A @ 8.3 ms - Robust surge handling for inrush and transient events in power supplies |
| TJ Range | −65°C to +125°C - Wide operating junction temperature supporting industrial and automotive ambient environments |
| RθJA | 52°C/W - Thermal performance baseline for DO-15 mounting on standard PCB copper area |
Pinout & Package
APD240VG-E1 uses the DO-15 axial-leaded package with cathode identified by a band marking. The device contains two Schottky diodes sharing a common cathode terminal; anode terminals are isolated and accessible via separate leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Common cathode node | Shared output node for dual-diode configuration; connects to system ground or return path |
| Anode 1 (lead 1) | First anode | Input node for first rectifier path; used in dual-output or redundancy configurations |
| Anode 2 (lead 2) | Second anode | Independent input node for second rectifier path; enables dual-input or OR-ing functionality |
Key Features
| Feature | Design Value |
|---|---|
| Low forward voltage | 0.5 V max at 2 A ensures <1 W conduction loss per diode at full load |
| Guard-ring structure | Enhances ruggedness against voltage transients and mechanical stress during board assembly |
| +125°C junction rating | Enables reliable operation in enclosed or thermally constrained power converter enclosures |
| Pb-free, RoHS-compliant finish | Matte tin annealed over copper leadframe meets JEDEC J-STD-020 moisture sensitivity Level 1 |
| Green packaging | Halogen- and antimony-free molding compound complies with Diodes Inc.'s "Green" definition (<900 ppm Br/Cl, <1000 ppm Sb) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SB240-E3/54 | Single-diode DO-41 package; identical 40 V / 2 A / 0.5 V specs but no dual-anode topology | Lacks integrated dual-anode functionality; requires two discrete devices for same circuit role | Select when space allows discrete placement and shared-cathode integration is unnecessary |
| SS24-E3/57T | SOD-123 package; same VF and VRRM but lower IFSM (30 A) and higher RθJA (200°C/W) | Not suitable for high-surge or thermally demanding layouts; limited to low-power DC-DC outputs | Choose only for ultra-compact, low-current applications where DO-15 mechanical robustness is not required |
Compared with SB240-E3/54 and SS24-E3/57T, APD240VG-E1 uniquely provides dual-anode rectification in a single DO-15 package with 50 A surge rating and 52°C/W thermal resistance-making it optimal for space-constrained, high-reliability power stages requiring integrated redundancy or OR-ing.

FAQ
What is the pin configuration of APD240VG-E1?
The APD240VG-E1 has three terminals in a DO-15 package: one common cathode (identified by a band) and two isolated anodes (leads 1 and 2). Top-view marking confirms cathode-band orientation, and datasheet Figure 1 explicitly labels both anodes as electrically independent inputs sharing the banded cathode node.
Does APD240VG-E1 support surface-mount assembly?
No - APD240VG-E1 is an axial-leaded DO-15 package intended for through-hole mounting. Its 0.375" (9.5 mm) lead length and mechanical outline (DS36971 Rev. 4–2, page 6) specify axial insertion and soldering. For SMD alternatives, consider APD240KDTR-G1 (SOD-123) or APD240VRTR-G1 (DO-214AC).
What is the maximum allowable junction temperature during continuous operation?
The absolute maximum operating junction temperature is +125°C, as specified in the "Maximum Ratings" table (DS36971 Rev. 4–2, page 4). Derating curves confirm 2.0 A IF(AV) is maintained up to +125°C lead temperature, provided thermal resistance (RθJA = 52°C/W) and PCB copper area meet Diodes' recommended layout guidelines.
Is APD240VG-E1 halogen-free and RoHS 3 compliant?
Yes - APD240VG-E1 carries the "Green" designation per Diodes Incorporated's definition: <900 ppm bromine, <900 ppm chlorine, <1000 ppm antimony, and full compliance with EU Directive 2015/863/EU (RoHS 3). The matte tin finish and molding compound are documented in Notes 1–3 of DS36971.
