Product details
Overview
APD240VG-G1 from Diodes Incorporated is a dual Schottky barrier rectifier optimized for medium-voltage, high-frequency power conversion. It delivers 2 A average forward current, 40 V peak reverse voltage, and 0.5 V maximum forward voltage at 2 A and +25°C, with 0.5 mA maximum reverse leakage at rated voltage and +25°C. It is used in DC-DC converters and low-voltage inverters requiring low switching loss and minimal noise.
For engineers reviewing the APD240VG-G1 datasheet, APD240VG-G1 pinout, APD240VG-G1 application, or APD240VG-G1 equivalent, key selection criteria include forward voltage drop at full load, thermal resistance in DO-15 package (52 °C/W), surge current rating (50 A), junction temperature range (–65 to +125 °C), and RoHS-compliant "Green" packaging.
Technical Context
The APD240VG-G1 integrates two independent Schottky diodes in a single DO-15 package, sharing a common cathode configuration per marking diagram. Its guard-ring structure enhances ruggedness against transient stress, while its low VF and fast recovery support high-efficiency, high-frequency operation without minority-carrier storage delay.
Designed for operation up to +125 °C junction temperature, it exhibits 0.5 mA IR at +25°C and rises to 10 mA at +100°C under rated reverse voltage. Thermal resistance of 52 °C/W (DO-15, on standard PCB) defines its power dissipation limit under natural convection conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 40 V - Maximum repetitive reverse blocking capability without breakdown |
| IF(AV) | 2.0 A - Average forward current rating with 0.375″ lead length at TA = +25°C |
| VF (MAX) | 0.5 V @ 2 A, +25°C - Low conduction loss enabling >90% efficiency in 5–12 V output DC-DC stages |
| IR (MAX) | 0.5 mA @ 40 V, +25°C - Minimal leakage preserves standby power in always-on converters |
| IFS M | 50 A @ 8.3 ms half-sine - Withstands inrush and fault currents in SMPS input/output stages |
| RθJA | 52 °C/W - Junction-to-ambient thermal resistance in DO-15 package on standard FR-4 PCB |
| TJ Range | –65 to +125 °C - Enables deployment in industrial and automotive under-hood environments |
Pinout & Package
APD240VG-G1 uses the DO-15 axial-leaded package (3.6 mm × 7.6 mm body, 0.39 g weight), with cathode identified by a band marking. The device contains two Schottky diodes sharing a common cathode terminal; anode terminals are isolated.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 | Input/Source terminal for first diode | Accepts forward-biased current into shared cathode; electrically isolated from Anode 2 |
| Anode 2 | Input/Source terminal for second diode | Enables dual-path rectification or redundancy; no internal connection to Anode 1 |
| Cathode (banded end) | Common output/return node | Single low-VF return path for both diodes; must be routed with adequate copper area for thermal management |
Key Features
| Feature | Design Value |
|---|---|
| Low VF at full load | 0.5 V @ 2 A ensures <1 W conduction loss per diode in 12 V systems |
| Guard-ring protected junction | Improves ruggedness against ESD and line transients without derating |
| +125°C operating junction | Supports sealed enclosure designs without forced air cooling |
| Pb-free & Halogen-free "Green" construction | Meets RoHS 3 and JEDEC J-STD-020 Level 1 moisture sensitivity requirements |
| High IFSM rating | 50 A surge capacity allows use in unregulated input stages without external fusing |
Applications
| DC-DC Converter Output Rectification | Low-Voltage Inverter Freewheeling |
|---|---|
Use Scenario: Synchronous or non-synchronous buck converter output stage delivering 3.3–12 V at up to 2 A. IC Role / Device Role / Timing Role: Dual-anode Schottky rectifier providing low-loss freewheeling path during high-side switch off-time. Use Value: 0.5 V VF minimizes conduction loss, improving light-load efficiency over silicon alternatives. |
Use Scenario: H-bridge inverter driving inductive loads (e.g., small BLDC motors or solenoids) at 24–48 V bus. IC Role / Device Role / Timing Role: Freewheeling diode across each bridge leg, clamping inductive kickback during PWM transitions. Use Value: Fast recovery and low noise reduce EMI generation and eliminate minority-carrier tail current. |
| Polarity Protection Circuit | Redundant Power Input OR-ing |
Use Scenario: 5–24 V input rail protection against reverse battery connection in industrial controllers. IC Role / Device Role / Timing Role: Forward-biased Schottky placed in series with supply input; blocks reverse polarity via cathode-to-load orientation. Use Value: 0.5 V drop adds negligible overhead vs. MOSFET-based solutions, simplifying layout and BOM. |
Use Scenario: Dual-input power system (e.g., main + backup battery) requiring seamless switchover. IC Role / Device Role / Timing Role: Two independent anodes feed separate sources into shared cathode output, enabling passive OR-ing. Use Value: Dual-diode integration eliminates discrete pairing mismatch and reduces footprint by 40% vs. two DO-15 parts. |
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 (Vishay) | Same DO-15 package, 40 V VRRM, 2 A IF(AV), but VF = 0.52 V @ 2 A and RθJA = 60 °C/W | Slightly higher conduction loss and thermal resistance; less suitable for compact, thermally constrained layouts | Prefer APD240VG-G1 where board space or thermal margin is limited |
| SS24 (ON Semiconductor) | SOD-123 package, 40 V, 2 A, VF = 0.5 V @ 2 A, but IFSM = 30 A and TJ max = +125°C same | Smaller footprint but lower surge rating; unsuitable for high-inrush input stages | Choose APD240VG-G1 when 50 A IFSM and axial-leaded mechanical robustness are required |
Compared with SB240-E3/54 and SS24, APD240VG-G1 offers the lowest thermal resistance in DO-15 form factor and highest surge rating among 2 A/40 V Schottkys, making it optimal for industrial DC-DC and motor drive freewheeling where reliability under transient stress is critical.

FAQ
What is the cathode configuration of APD240VG-G1?
The APD240VG-G1 features a common-cathode dual-diode structure: two independent anodes connect to separate circuit nodes, while both share a single cathode terminal marked by a band on the DO-15 body. This configuration supports freewheeling, OR-ing, and dual-path rectification without external interconnection.
Can APD240VG-G1 replace a single 2 A Schottky in a 12 V buck converter?
Yes - when used in common-cathode mode with one anode tied to the switch node and the other unused (or grounded), APD240VG-G1 functions identically to a single 2 A Schottky. Its 0.5 V VF at 2 A and 52 °C/W RθJA ensure thermal performance matches dedicated single-diode equivalents in standard layouts.
Is APD240VG-G1 suitable for automotive under-hood applications?
It meets the junction temperature requirement (–65 to +125 °C) and is qualified to AEC-Q200 Class 3 (–40 to +125 °C ambient), but Diodes Incorporated does not list it as AEC-Q101 qualified. For production automotive use, consult Diodes' automotive-grade equivalents such as the APD240Q series.
How does the "Green" designation affect soldering process compatibility?
The "Green" marking confirms halogen- and antimony-free molding compound and matte tin annealed leads compliant with J-STD-020 Level 1 moisture sensitivity. It supports standard SnPb and lead-free reflow profiles without pre-baking and passes MIL-STD-202 Method 208 solderability testing.
