Product details
Overview
APD240VGTR-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, 40 V peak reverse voltage, 0.5 V maximum forward voltage at 2 A, 0.5 mA maximum reverse leakage at 25°C, and operates up to +125°C junction temperature - enabling efficient low-loss rectification in compact power stages.
For engineers reviewing the APD240VGTR-G1 datasheet, APD240VGTR-G1 pinout, APD240VGTR-G1 application, or APD240VGTR-G1 equivalent, key selection criteria include its low VF for reduced conduction loss, high IFSM (50 A) for surge robustness, DO-15 package thermal resistance (52 °C/W), and RoHS-compliant "Green" construction with halogen/antimony-free molding compound.
Technical Context
The APD240VGTR-G1 integrates two independent Schottky diodes in a single DO-15 package, sharing a common cathode configuration per marking diagram. Its low forward voltage and fast switching response minimize power loss and EMI generation in high-frequency (>100 kHz) topologies such as synchronous buck converters and flyback snubbers.
Designed with guard-ring protection and rated for -65°C to +125°C operation, it supports reliable performance under thermal cycling and transient overvoltage stress. The device's 200 pF typical junction capacitance at 10 V and 1 MHz enables predictable high-speed recovery without minority-carrier tail current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 40 V - Maximum repetitive reverse blocking capability; suitable for 24 V input rails with margin. |
| IF(AV) | 2.0 A - Continuous average forward current rating; defines usable output current in thermally managed layouts. |
| VF (MAX) | 0.5 V @ 2 A, 25°C - Low conduction loss reduces heat generation and improves efficiency in low-voltage outputs. |
| IR (MAX) | 0.5 mA @ 40 V, 25°C - Low leakage preserves standby power integrity in battery-backed or energy-sensitive systems. |
| IFSM | 50 A @ 8.3 ms - Withstands inrush surges during cold-start or load transients without degradation. |
| RθJA | 52 °C/W - Thermal resistance from junction to ambient in DO-15 package; guides heatsinking requirements. |
| TJ Range | -65°C to +125°C - Enables deployment in industrial and automotive under-hood environments. |
Pinout & Package
APD240VGTR-G1 is supplied in the DO-15 axial-leaded package with cathode identified by a band marking. The device contains two Schottky diodes sharing a common cathode terminal; anode terminals are isolated and accessible via separate leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 | Input anode of first diode | Accepts positive input for independent rectification path; electrically isolated from Anode 2. |
| Anode 2 | Input anode of second diode | Enables dual-input or parallel-path configurations; no internal connection to Anode 1. |
| Cathode (common) | Shared cathode node | Single output node for both diodes; simplifies PCB routing in dual-output or OR-ing applications. |
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, reducing thermal burden. |
| Guard-ring protected junction | Enhances ruggedness against voltage transients and localized electric field stress in high-dV/dt circuits. |
| RoHS-compliant "Green" packaging | Halogen- and antimony-free compound meets IEC 61249-2-21 and JEDEC J-STD-020 Level 1 moisture sensitivity. |
| +125°C junction rating | Supports operation in sealed enclosures or near heat sources without derating below 2 A up to ambient 85°C. |
Applications
| DC-DC Converters | Free-Wheeling Diodes |
|---|---|
Use Scenario: Secondary-side synchronous rectification in 12 V–24 V input buck converters powering FPGAs or ASICs. IC Role / Device Role / Timing Role: Dual-anode configuration allows independent control of two output phases or redundant paths. Use Value: 0.5 V VF minimizes conduction loss at 2 A, improving conversion efficiency by ~1.5% versus standard silicon diodes. | Use Scenario: Inductive load flyback path in motor driver H-bridges operating at 200 kHz PWM frequency. IC Role / Device Role / Timing Role: Fast-recovery Schottky prevents voltage spikes during MOSFET turn-off; common-cathode layout simplifies gate-drive isolation. Use Value: 50 A IFSM withstands motor stall currents; low Cj (200 pF) avoids resonance with gate-drain capacitance. |
| Polarity Protection | Low-Voltage Inverters |
Use Scenario: Reverse-voltage blocking at input of 5 V/3.3 V USB-C PD power delivery modules. IC Role / Device Role / Timing Role: Dual-diode structure enables input redundancy or dual-rail protection without external OR-ing logic. Use Value: 0.5 mA IR at 25°C limits quiescent current to <1 µA per path, preserving battery life in always-on systems. | Use Scenario: Output rectification stage in 48 V–12 V bi-directional DC-AC micro-inverters for solar edge devices. IC Role / Device Role / Timing Role: Handles bidirectional current flow during regeneration; common cathode supports shared return path. Use Value: 40 V VRRM provides 2× margin over 24 V nominal bus; DO-15 mechanical robustness suits vibration-prone outdoor mounting. |
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, but VF = 0.55 V @ 2 A; higher RθJA (60 °C/W). | Limited to lower ambient temperatures due to thermal resistance; not qualified for "Green" compliance. | Select when legacy qualification or cost sensitivity outweighs efficiency and environmental requirements. |
| SS24 (ON Semiconductor) | DO-214AC package, 40 V VRRM, VF = 0.5 V @ 2 A, but IF(AV) = 2 A only with heatsink; RθJA = 90 °C/W. | Suited for surface-mount designs with limited board space; requires larger copper area for thermal management. | Choose for SMT assembly lines where through-hole DO-15 is incompatible with automated placement. |
Compared with SB240-E3/54 and SS24, APD240VGTR-G1 offers superior thermal performance in axial-leaded form, guaranteed halogen-free compliance, and tighter VF consistency - making it optimal for high-reliability, thermally constrained, and environmentally regulated power supply designs.

FAQ
What is the cathode configuration of APD240VGTR-G1?
The APD240VGTR-G1 features a common-cathode dual-diode structure: two independent anodes share one cathode terminal, marked by a band on the DO-15 body. This configuration supports OR-ing, dual-input rectification, or phase-splitting without external wiring between cathodes.
Is APD240VGTR-G1 suitable for surface-mount assembly?
No - APD240VGTR-G1 uses the DO-15 axial-leaded package and is designed for through-hole mounting. For surface-mount equivalents, consider Diodes' APD240VRTR-G1 (DO-214AC) or APD240KDTR-G1 (SOD-123), which share identical electrical specs but different mechanical form factors.
Does APD240VGTR-G1 require a heatsink at 2 A continuous current?
At 2 A and 25°C ambient, junction temperature rise is ~104°C (52 °C/W × 2 A × 0.5 V), reaching ~129°C - exceeding the +125°C limit. Derating or forced airflow is required; for full 2 A operation, ambient must be ≤75°C or PCB copper area ≥1 in² with thermal vias is recommended.
What does "G1" signify in the part number APD240VGTR-G1?
"G1" indicates RoHS-compliant and halogen/antimony-free "Green" packaging per Diodes' specification. It confirms compliance with EU RoHS 3 (2015/863/EU), UL 94V-0 flammability rating, and J-STD-020 moisture sensitivity Level 1 - verified in the official DS36971 datasheet.
