Product details
Overview
APD140VDTR-G1 from Diodes Incorporated is a dual Schottky barrier rectifier optimized for high-frequency DC-DC converters and low-voltage inverters, featuring 40 V reverse voltage rating, 1 A average forward current, 0.5 V max forward voltage at 1 A, 0.5 mA max reverse leakage at 25°C, and +125°C junction temperature capability.
For engineers reviewing the APD140VDTR-G1 datasheet, APD140VDTR-G1 pinout, APD140VDTR-G1 application, or APD140VDTR-G1 equivalent, key selection criteria include low switching loss in SMPS, thermal performance in compact layouts, RoHS-compliant green packaging (DO-41, matte tin finish), and surge robustness (35 A IFSM) in transient-prone power paths.
Technical Context
The APD140VDTR-G1 integrates two independent Schottky diodes in a single DO-41 package with common-cathode configuration, enabling synchronous rectification or freewheeling in buck/boost topologies. Its low VF and fast recovery minimize conduction and switching losses at frequencies up to several hundred kHz.
Designed for medium-voltage operation (≤40 V), it leverages guard-ring structure for mechanical stress protection and operates reliably across –65°C to +125°C junction range. Thermal resistance is 65°C/W (RθJA, DO-41 on standard PCB), supporting continuous 1 A conduction under proper layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 40 V - Maximum repetitive reverse blocking voltage; sets upper limit for input/output rail voltage in DC-DC stages |
| IF(AV) | 1.0 A - Average forward current per diode; defines continuous power handling in freewheeling or output rectification |
| VF (max) | 0.5 V @ 1 A, 25°C - Low conduction loss reduces heat generation and improves efficiency in high-current, low-VOUT designs |
| IR (max) | 0.5 mA @ 25°C - Low leakage preserves regulation in standby mode and minimizes wasted current in polarity protection |
| IFSM | 35 A (8.3 ms half-sine) - Withstands inrush and fault currents without degradation; critical for reliability in unregulated inputs |
| TJ Range | –65°C to +125°C - Enables deployment in industrial ambient environments without derating below full current |
Pinout & Package
APD140VDTR-G1 uses the DO-41 axial-leaded package with cathode marked by band. It contains two Schottky diodes sharing a common cathode terminal and separate anodes (Anode 1, Anode 2).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 | Input node for first diode | Connects to switching node or input rail in dual-path rectification or OR-ing applications |
| Anode 2 | Input node for second diode | Enables independent control of two current paths-e.g., dual-output DC-DC or redundant supply monitoring |
| Cathode | Common output node | Serves as shared return path; simplifies PCB routing and reduces parasitic inductance in high-dI/dt circuits |
Key Features
| Feature | Design Value |
|---|---|
| Low forward voltage | 0.5 V max at 1 A ensures ≤0.5 W conduction loss per diode, reducing heatsink requirements in space-constrained SMPS |
| Guard-ring protected junction | Enhances mechanical ruggedness during board flexure or thermal cycling-critical for automotive and industrial mounting |
| +125°C operating junction | Supports full-rated current without derating in enclosed enclosures or near hot components (e.g., MOSFETs, inductors) |
| RoHS-compliant green packaging | Halogen- and antimony-free molding compound (Br+Cl <1500 ppm, Sb <1000 ppm) meets strict environmental compliance mandates |
Applications
| Low Voltage High Frequency Inverters | DC-DC Converters |
|---|---|
Use Scenario: Bidirectional flyback or resonant inverter stage in portable medical battery chargers operating at 200–500 kHz. IC Role / Device Role / Timing Role: Freewheeling diode pair clamping transformer leakage energy and enabling zero-voltage switching transitions. Use Value: 0.5 V VF minimizes conduction loss during high-duty-cycle operation, improving overall system efficiency by ≥1.2% versus standard silicon diodes. | Use Scenario: Secondary-side synchronous rectification in isolated 12 V → 3.3 V/1 A buck-derived converter for FPGA power rails. IC Role / Device Role / Timing Role: Dual-anode configuration allows independent gate drive timing for each diode leg in active clamp or phase-shifted topologies. Use Value: Common-cathode layout reduces trace inductance and EMI emissions compared to discrete dual-diode placement. |
| Free Wheeling | Polarity Protection |
Use Scenario: Inductive load suppression in 24 V industrial solenoid drivers with PWM control. IC Role / Device Role / Timing Role: Provides low-loss recirculation path during MOSFET turn-off, limiting voltage spikes to ≤45 V. Use Value: 35 A IFSM withstands repeated 20 A inductive kick events over 10⁶ cycles without parameter shift. | Use Scenario: Reverse-voltage protection at main input of 5 V USB-powered IoT sensor node with Li-ion backup. IC Role / Device Role / Timing Role: Blocks reverse current flow when external adapter is disconnected while battery remains active. Use Value: 0.5 mA IR at 25°C limits standby drain to <1 μA per diode, extending battery life beyond 12 months in sleep mode. |

FAQ
What is the package type and lead finish of APD140VDTR-G1?
APD140VDTR-G1 uses the DO-41 axial-leaded package with matte tin annealed over copper leadframe. It is RoHS-compliant and halogen/antimony-free ("Green" per Diodes' specification), meeting JEDEC J-STD-020 moisture sensitivity Level 1.
Is APD140VDTR-G1 still in active production?
No-APD140VDTR-G1 is marked obsolete in Diodes' official documentation (DS36974 Rev. 4, April 2018) with no alternate part offered. Aetrix Electronics maintains limited legacy stock for design continuity and repair programs only.
How does the common-cathode configuration affect circuit layout?
The common-cathode topology consolidates the output node, reducing PCB trace length and loop area between diodes and output capacitor. This lowers radiated EMI and improves transient response in high-speed switching applications like point-of-load regulators.
What is the maximum surge current rating and test condition?
APD140VDTR-G1 supports 35 A non-repetitive peak forward surge current (IFSM) under an 8.3 ms single half-sine wave condition at rated load, verified per JEDEC standards. This rating applies at maximum junction temperature and assumes proper thermal management.
