Product details
Overview
APD340VGTR-E1 from Diodes Incorporated is a dual anode, 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 max 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 APD340VGTR-E1 datasheet, APD340VGTR-E1 pinout, APD340VGTR-E1 application, or APD340VGTR-E1 equivalent, key selection criteria include its 0.5 V VF at 3 A, 80 A non-repetitive surge rating, +125°C junction temperature capability, and DO-214AC thermal resistance of 75°C/W with recommended pad layout.
Technical Context
The APD340VGTR-E1 integrates two Schottky diodes sharing a common cathode terminal, enabling dual-path rectification or polarity protection in compact layouts. Its guard-ring structure enhances ruggedness against transient stress and improves reliability under repetitive surge conditions.
Designed for high-frequency operation up to several hundred kHz, it minimizes reverse recovery charge (Qrr ≈ 0 nC) and junction capacitance (typ. 120 pF at 4 V), reducing EMI generation and improving efficiency in switch-mode power supplies.
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, +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 preserving standby power integrity |
| IFSM | 80 A @ 8.3 ms half-sine - Withstands inrush and fault currents in power supply startup and overload events |
| TJ range | −50°C to +125°C - Supports operation in industrial ambient environments without derating below 3 A |
| RθJA | 75°C/W - Thermal performance achievable with standard DO-214AC PCB pad layout per Diodes Inc. guidelines |
Pinout & Package
APD340VGTR-E1 is housed in a surface-mount DO-214AC (SMA) plastic package with matte tin–annealed copper leadframe, UL 94V-0 rated molding compound, and green (halogen/antimony-free) compliance. Cathode is marked by a green band on the top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 | Input node for first Schottky diode | Accepts positive input for independent rectification path; electrically isolated from Anode 2 |
| Anode 2 | Input node for second Schottky diode | Enables dual-input/single-output configuration or redundancy; no internal connection to Anode 1 |
| Cathode | Common output node | Shared return path for both diodes; must be routed with low-inductance trace for high-frequency stability |
Key Features
| Feature | Design Value |
|---|---|
| Low VF (0.5 V @ 3 A) | Reduces conduction loss by ~40% vs. comparable silicon rectifiers, directly improving light-load efficiency |
| Guard-ring protected junction | Prevents premature edge breakdown under voltage transients, extending lifetime in noisy power rails |
| +125°C operating junction temperature | Permits full 3 A current rating in sealed enclosures or high-ambient industrial settings without forced air |
| DO-214AC "Green" package | RoHS 3 compliant, halogen- and antimony-free, with moisture sensitivity level 1 for uncomplicated SMT reflow |

FAQ
What is the maximum junction temperature for continuous operation?
The APD340VGTR-E1 supports continuous operation up to +125°C junction temperature. At this temperature, the average forward current must be derated to approximately 1.8 A per diode based on the forward current derating curve in DS36969 Rev. 3–2, Figure 5. Ambient temperature and PCB thermal design directly impact achievable current.
Is APD340VGTR-E1 pin-compatible with APD340VRTR-G1?
Yes - both APD340VGTR-E1 and APD340VRTR-G1 use identical DO-214AC package and share identical pinout: dual anodes and common cathode. The difference lies only in tape-and-reel packaging specifications and marking codes; electrical and thermal performance are fully identical per datasheet DS36969.
Does APD340VGTR-E1 have a specified reverse recovery time (trr)?
No - as a Schottky barrier rectifier, the APD340VGTR-E1 has no minority-carrier storage mechanism and therefore exhibits no measurable reverse recovery time. Its switching behavior is governed by junction capacitance (120 pF typical at 4 V) and series resistance, making it suitable for frequencies beyond 1 MHz without trr-related losses.
Can APD340VGTR-E1 be used in automotive applications?
The APD340VGTR-E1 is not AEC-Q200 qualified and lacks automotive-grade qualification documentation. While its −50°C to +125°C operating range meets some automotive ambient requirements, Diodes Incorporated does not specify automotive stress test data (e.g., HTOL, TC, ESD) for this part. Use in automotive systems requires customer qualification per application-specific requirements.
