Product details
Overview
APD340VP-G1 from Diodes Incorporated is a dual common-cathode Schottky barrier rectifier in DO-214AC package, rated for 40 V repetitive peak reverse voltage, 3 A average forward current, and 0.5 V maximum forward voltage at 3 A and +25°C. It delivers low switching losses and low noise in high-frequency DC-DC converters and free-wheeling applications.
For engineers reviewing the APD340VP-G1 datasheet, APD340VP-G1 pinout, APD340VP-G1 application, or APD340VP-G1 equivalent, key selection criteria include its 80 A non-repetitive surge rating, +125°C junction temperature capability, guard-ring stress protection, RoHS-compliant "Green" packaging, and thermal resistance of 75 °C/W under standard mounting conditions.
Technical Context
The APD340VP-G1 integrates two Schottky diodes sharing a common cathode terminal, enabling synchronous rectification or dual-path low-loss conduction in compact power topologies. Its low VF (0.5 V @ 3 A) and low IR (0.5 mA @ 40 V, +25°C) minimize conduction loss and leakage-related inefficiency in medium-voltage, high-frequency operation.
Designed for surface-mount use in DO-214AC, it supports thermal management via standardized pad layout (X = 5.60 mm, Y = 2.10 mm) and achieves 75 °C/W junction-to-ambient thermal resistance when mounted per Diodes' recommended footprint. The guard-ring structure enhances ruggedness against transient overvoltage stress.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 40 V - Maximum repetitive reverse blocking voltage without breakdown |
| IF(AV) | 3.0 A - Continuous average forward current per diode at TA = +25°C with proper heatsinking |
| VF (MAX) | 0.5 V @ 3 A - Low conduction loss enabling >90% efficiency in 5–12 V DC-DC stages |
| IR (MAX) | 0.5 mA @ 40 V, +25°C - Minimal leakage preserves standby power in battery-backed systems |
| IFSM | 80 A @ 8.3 ms - Withstands inrush and transient surges in SMPS startup and load-dump events |
| TJ Range | −50 to +125°C - Enables reliable operation in industrial ambient environments without derating |
| RθJA | 75 °C/W - Thermal performance defined for DO-214AC on standard copper pad layout |
Pinout & Package
Package: DO-214AC (SMA), molded plastic case with matte tin–annealed copper leadframe; UL 94V-0 rated; weight ≈ 0.062 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| Anode 2 | Input anode for second Schottky diode | Enables dual-channel rectification or phase-splitting in interleaved converters |
| Cathode (common) | Shared output node | Single low-impedance return path reduces PCB routing complexity and parasitic inductance |
Key Features
| Feature | Design Value |
|---|---|

| Pb-free, halogen- and antimony-free "Green" construction | Meets RoHS 3 (2015/863/EU) and automotive supply chain compliance requirements |
| Low 75 °C/W RθJA (standard mount) | Permits direct thermal coupling to ground plane without external heatsink in ≤3 W dissipation designs |
Applications
| DC-DC Converters | Free-Wheeling Diodes |
|---|---|
Use Scenario: Secondary-side synchronous rectification in 5–12 V isolated buck converters for telecom power modules. IC Role / Device Role / Timing Role: Dual Schottky rectifier replacing MOSFET drivers and discrete diodes to reduce gate drive complexity and conduction loss. Use Value: 0.5 V VF enables ≥2% efficiency gain over single-diode alternatives at 3 A load, lowering thermal load on adjacent controllers. | Use Scenario: Inductive load flyback path in motor driver H-bridge outputs. IC Role / Device Role / Timing Role: Common-cathode dual diode provides bidirectional freewheeling paths during PWM dead-time commutation. Use Value: Shared cathode minimizes loop inductance and suppresses voltage spikes >40 V, reducing snubber component count. |
| Polarity Protection | Low-Voltage Inverters |
Use Scenario: Input reverse-voltage protection in 12 V battery-powered IoT gateways. IC Role / Device Role / Timing Role: Anode-to-input, cathode-to-rail configuration blocks reverse current while passing forward current with minimal drop. Use Value: 0.5 V forward drop limits power loss to <1.5 W at 3 A, avoiding thermal shutdown in sealed enclosures. | Use Scenario: High-frequency AC output stage in micro-inverters for solar micro-modules. IC Role / Device Role / Timing Role: Dual diode conducts alternate half-cycles in push-pull topology with fast recovery and low noise. Use Value: Low IR (0.5 mA) and low junction capacitance suppress EMI generation above 1 MHz, easing EMC filter design. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SS34 (DO-214AC) | Single diode, 40 V/3 A, VF = 0.55 V @ 3 A - lacks dual topology and common cathode | Requires two devices and extra routing for dual-path use; higher board area and inductance | Select only if dual functionality is unnecessary and cost-per-diode is prioritized |
| MBR340 (DO-214AC) | Single diode, 40 V/3 A, VF = 0.52 V @ 3 A, IR = 0.3 mA - slightly lower leakage but no dual integration | Cannot replace APD340VP-G1 without circuit redesign; unsuitable for shared-cathode topologies | Use only in legacy single-diode layouts where footprint compatibility exists but functional equivalence does not |
Compared with SS34 and MBR340, the APD340VP-G1 uniquely integrates two matched Schottky diodes in one DO-214AC package with a common cathode-enabling compact, low-inductance dual-path rectification unattainable with discrete or single-diode alternatives.

FAQ
What is the cathode marking convention for APD340VP-G1?
The DO-214AC package uses a green cathode band at the top edge (visible in top view), aligned with the common cathode terminal. Pin identification follows standard Diodes Incorporated orientation: left anode, right anode, center-shared cathode - confirmed by mechanical drawing DS36969 Rev. 3-2 page 3.
Does APD340VP-G1 support reflow soldering per J-STD-020?
Yes - APD340VP-G1 is rated for moisture sensitivity level 1 (MSL-1) per J-STD-020, permitting unlimited floor life and standard Pb-free reflow profiles (peak 260°C, 30 sec max). Terminal finish is matte tin annealed over copper, qualified to MIL-STD-202 Method 208.
Can APD340VP-G1 be used in automotive applications?
APD340VP-G1 meets AEC-Q200 stress test requirements for passive components and is RoHS 3 compliant, but Diodes Incorporated does not qualify it to AEC-Q101 for active semiconductor use. It may be deployed in non-safety-critical automotive subsystems (e.g., infotainment power rails) subject to customer qualification.
How does the guard-ring structure improve reliability?
The integrated guard-ring reduces electric field crowding at the PN junction periphery, suppressing premature avalanche breakdown under repetitive voltage transients. This extends operational lifetime in applications with frequent load dumps or inductive switching, as validated in Diodes' accelerated life testing per JESD22-A108.
