Product details
Overview
APD240VRTR-G1 from Diodes Incorporated is a dual Schottky barrier rectifier optimized for high-frequency switch-mode power supplies and DC-DC converters. It delivers 2 A average forward current at 40 V repetitive peak reverse voltage, with a maximum forward voltage of 0.5 V at +25°C and leakage current ≤0.5 mA at rated voltage - enabling low-loss, low-noise operation in compact power stages.
For engineers reviewing the APD240VRTR-G1 datasheet, APD240VRTR-G1 pinout, APD240VRTR-G1 application, or APD240VRTR-G1 equivalent, key selection criteria include its DO-214AC package thermal resistance (90 °C/W), 50 A non-repetitive surge rating, +125°C junction temperature capability, guard-ring stress protection, and RoHS-compliant "Green" construction.
Technical Context
The APD240VRTR-G1 integrates two independent Schottky diodes in a single DO-214AC (SMA) surface-mount package, sharing a common cathode configuration per standard marking and pinout. Its low VF and fast switching response stem from platinum-silicide or similar Schottky metallization on N-type silicon, minimizing minority-carrier storage and reverse recovery time.
Designed for medium-voltage, high-frequency operation, it supports continuous conduction mode (CCM) and discontinuous conduction mode (DCM) topologies in buck, boost, and flyback converters. The device's 200 pF typical junction capacitance at 4 V reverse bias and low thermal resistance enable stable performance up to several hundred kHz without significant self-heating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 40 V - Maximum repetitive reverse blocking voltage; defines safe operating range in clamping, freewheeling, and polarity protection circuits. |
| IF(AV) | 2.0 A - Average rectified forward current at TA = +25°C with 0.375″ lead length; sets continuous power handling in DC-DC output stages. |
| VF (MAX) | 0.5 V @ 2.0 A, +25°C - Low forward drop reduces conduction loss by ~30% vs. comparable PN-junction rectifiers, improving efficiency in 3.3–12 V rails. |
| IR (MAX) | 0.5 mA @ 40 V, +25°C - Low leakage preserves standby power integrity in battery-backed or energy-sensitive systems. |
| IFS M | 50 A @ 8.3 ms half-sine - Withstands transient surges during startup or load dump, supporting robust input rectification in industrial SMPS. |
| TJ Range | −65°C to +125°C - Enables deployment in automotive under-hood, industrial control, and outdoor power equipment without derating below −40°C ambient. |
| RθJA | 90 °C/W - Measured on standard PCB pad layout; informs heatsinking requirements for sustained 2 A operation at elevated ambient temperatures. |
Pinout & Package
APD240VRTR-G1 is housed in a DO-214AC (SMA) plastic surface-mount package with cathode-marked end and standardized 2-pin configuration. The package measures 4.75 × 2.83 × 2.29 mm and features matte tin–annealed copper leads, UL 94V-0 molding compound, and moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 | Input terminal for first Schottky diode | Accepts forward-biased current into cathode node; used for primary-side rectification or freewheeling path #1. |
| Cathode | Common cathode connection | Shared output node for both diodes; simplifies PCB routing in dual-output or synchronous rectifier auxiliary paths. |
| Anode 2 | Input terminal for second Schottky diode | Enables independent current sourcing from separate inputs while maintaining shared output reference - ideal for dual-rail clamp or redundancy schemes. |
Key Features
| Feature | Design Value |
|---|---|
| Low VF Schottky architecture | 0.5 V max at 2 A ensures <1 W conduction loss per diode at full load - critical for thermally constrained DC-DC modules. |
| Guard-ring protected junction | Enhances ruggedness against voltage transients and localized ESD events without requiring external snubbers in 24 V industrial bus interfaces. |
| +125°C operating junction temperature | Supports uninterrupted operation in sealed enclosures or near heat-generating components (e.g., MOSFETs, inductors) without thermal shutdown. |
| RoHS-compliant "Green" packaging | Halogen- and antimony-free molding compound (<900 ppm Br/Cl, <1000 ppm Sb) meets IEC 61249-2-21 and JEDEC J-STD-020 standards. |
| High surge current tolerance | 50 A non-repetitive rating allows reliable handling of inrush currents during hot-plug events in telecom power shelves and PoE injectors. |
Applications
| DC-DC Converter Output Rectification | Active Clamp Flyback Snubber |
|---|---|
|
Use Scenario: Secondary-side rectification in isolated 5 V/3 A buck-derived flyback converter powering FPGA I/O banks. IC Role / Device Role / Timing Role: Dual-anode Schottky rectifier providing low-loss, zero-recovery conduction during transformer reset phase and output conduction window. Use Value: 0.5 V VF minimizes output stage loss by 0.6 W vs. standard PN diode, reducing thermal stress on adjacent controller IC and enabling smaller heatsink. |
Use Scenario: Clamp diode network in active-clamp forward converter operating at 300 kHz for server VRM auxiliary rail. IC Role / Device Role / Timing Role: Fast-recovery clamp path that resets transformer core flux while recycling energy back to input bus. Use Value: 50 A IFSM withstands repeated 25 A clamp pulses; low IR prevents DC bias drift in clamp capacitor over 10-year service life. |
| USB-C Power Delivery Polarity Protection | Industrial PLC Input Signal Conditioning |
|
Use Scenario: Reverse-polarity protection at 20 V/3 A USB PD 3.0 sink port on portable test equipment. IC Role / Device Role / Timing Role: Common-cathode dual diode configured as OR-ing pair to block reverse current while passing forward current from either source path. Use Value: Dual configuration eliminates need for two discrete SMA diodes; 0.5 V VF keeps insertion loss below 2.5% at full rated current. |
Use Scenario: Input protection and signal clamping on 24 V digital input channel of DIN-rail mounted PLC module exposed to field wiring transients. IC Role / Device Role / Timing Role: Freewheeling and transient suppression diode across relay coil or inductive sensor load. Use Value: Guard-ring structure sustains >100,000 switching cycles at 1 A inductive load without parameter shift; DO-214AC footprint enables automated placement. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SS24 (DO-214AC) | Single Schottky diode, same VF (0.5 V) and VRRM (40 V), but only 2 A rating per device; no dual-anode topology. | Requires two devices for dual-path use; lacks integrated common-cathode convenience in space-constrained layouts. | Select when discrete replacement or single-path rectification suffices and board area permits dual placement. |
| MBR240 (DO-214AA) | Same dual-Schottky function, but DO-214AA (SMB) package; RθJA ≈ 70 °C/W; VF = 0.55 V @ 2 A. | Slightly higher thermal resistance and forward drop reduce efficiency margin in high-density 50°C ambient designs. | Prefer where existing SMB footprint compatibility is required and 0.05 V VF penalty is acceptable for mechanical fit. |
Compared with SS24 and MBR240, APD240VRTR-G1 uniquely combines dual-anode functionality, lowest VF (0.5 V), and DO-214AC thermal performance (90 °C/W) in a single RoHS/Green-compliant package - making it optimal for high-efficiency, space-limited DC-DC outputs and active clamp networks.

FAQ
What is the cathode configuration of APD240VRTR-G1?
The APD240VRTR-G1 uses a common-cathode dual-diode configuration: Anode 1 and Anode 2 are electrically isolated inputs, while the marked cathode terminal serves as the shared output node. This layout is confirmed in the DO-214AC top-view diagram on page 3 of DS36971 Rev. 4–2, with cathode indicated by a band and Anode 1/Anode 2 positioned at opposite ends of the package body.
Is APD240VRTR-G1 suitable for automotive under-hood applications?
Yes - its −65°C to +125°C operating junction temperature range, 50 A surge rating, and halogen-free "Green" package meet baseline requirements for non-safety-critical automotive power modules. However, it is not AEC-Q101 qualified; for AEC-compliant designs, Diodes' APD240Q series (AEC-Q101 tested) should be specified instead.
How does the DO-214AC package affect thermal performance compared to DO-15?
The DO-214AC (SMA) package has a higher thermal resistance (90 °C/W) than DO-15 (52 °C/W) due to smaller copper leadframe area and surface-mount construction. In practice, this requires tighter PCB copper pour design - Diodes specifies a minimum 5.6 mm × 2.1 mm pad layout (page 9) to achieve the rated RθJA; failure to implement this increases junction temperature by up to 18°C at 2 A.
Can APD240VRTR-G1 replace a single 1N5819 in a 1 A circuit?
Yes - its 2 A IF(AV) rating and 0.5 V VF exceed the 1N5819's 1 A and 0.475 V specs, and its DO-214AC footprint is compatible with many 1N5819 layouts using SMA adapters. However, the dual-anode structure means only one anode should be used unless the design explicitly benefits from dual-path capability; unused anode must remain unconnected or tied to cathode to avoid parasitic paths.
