Product details
Overview
PDS1240CTL-13 from Diodes Incorporated is a 12A dual low-forward-voltage Schottky barrier rectifier in PowerDI5 package, rated for 40V peak repetitive reverse voltage, with 0.45V typical VF at 6A/100°C and 350µA max IR at 40V/25°C, used in low-voltage ORing, polarity protection, and high-frequency DC-DC output rectification.
For engineers reviewing the PDS1240CTL-13 datasheet, PDS1240CTL-13 pinout, PDS1240CTL-13 application, or PDS1240CTL-13 equivalent, key selection criteria include dual-leg thermal resistance (RθJC = 3°C/W per leg on Al board), 150A non-repetitive surge rating, guard ring die construction for transient immunity, and RoHS-compliant matte tin annealed terminals.
Technical Context
This dual Schottky rectifier integrates two independent 6A-rated anode-cathode junctions in a single PowerDI5 thermally enhanced surface-mount package. Each leg features guard ring die construction to suppress edge breakdown and improve surge robustness under transient conditions.
It operates across –65°C to +150°C junction temperature range, with forward voltage tightly specified (0.52V max at 6A/25°C) and reverse leakage limited to 20mA per leg at 40V/100°C - critical for maintaining efficiency in 5V–12V power rails where conduction loss dominates.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 40 V - Maximum peak repetitive reverse voltage each leg withstands without breakdown. |
| IO (per leg) | 6 A - Continuous average forward current per diode element at TA = 25°C with recommended PCB layout. |
| VF @ 6A/100°C | 0.45 V - Low conduction loss enabling >92% efficiency in 5V synchronous rectifier replacements. |
| IFSM (per leg) | 150 A - 8.3ms half-sine surge rating supports inrush and fault-current handling in POL converters. |
| RθJC (per leg) | 3 °C/W - Measured on 2"×2" aluminum board; enables 12W dissipation per leg before reaching 150°C junction limit. |
| IR @ 40V/25°C | 350 µA - Ultra-low leakage preserves standby power in always-on subsystems like USB-C PD controllers. |
Pinout & Package
Package: PowerDI5 - thermally optimized 3-pin surface-mount package with bottom-side heat sink, molded green compound (UL 94V-0), and matte tin annealed copper leadframe.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Left Pin | Anode 1 | Input terminal for first Schottky diode element; must be connected to PCB trace carrying input voltage. |
| Center Tab | Cathode (Common) | Shared cathode connection for both diodes; serves as primary thermal path to PCB copper pour or heatsink. |
| Right Pin | Anode 2 | Input terminal for second Schottky diode element; electrically isolated from Anode 1 but shares cathode node. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring die construction | Suppresses edge avalanche, improving ESD and surge immunity without derating VRRM. |
| Low VF at high temperature | 0.45V @ 6A/100°C ensures stable conduction loss in thermally constrained enclosures. |
| Thermal resistance RθJC = 3°C/W | Enables high-power density designs using only PCB copper as heatsink - no external heatsink required. |
| RoHS & Halogen-free compliance | Meets EU RoHS 3 (2015/863/EU), <900ppm Br/Cl, <1000ppm Sb - suitable for automotive and medical end equipment. |
Applications
| ORing Power Path | Polarity Protection |
|---|---|
Use Scenario: Dual-input redundant 5V/12V supply where either source powers the load without backfeed. IC Role / Device Role / Timing Role: Dual Schottky ORing diode providing low-loss forward conduction and blocking reverse current between supplies. Use Value: 0.45V VF minimizes voltage drop and heat generation versus MOSFET-based ideal diodes in cost-sensitive designs. | Use Scenario: Input protection for USB-C PD ports, industrial sensors, or battery-powered peripherals. IC Role / Device Role / Timing Role: Reverse-polarity blocking device placed in series with VBUS line to prevent damage from miswired connectors. Use Value: 350µA max IR at 25°C ensures negligible standby drain; 150A IFSM survives hot-plug transients. |
| DC-DC Output Rectification | High-Frequency Inverter Output |
Use Scenario: Secondary-side rectification in 300kHz–1MHz isolated flyback or forward converters delivering ≤12A total. IC Role / Device Role / Timing Role: Synchronous rectifier replacement offering zero gate-drive complexity and inherent soft recovery. Use Value: Junction capacitance <1000pF at 0V enables clean switching waveforms with minimal ringing in high-dV/dt environments. | Use Scenario: Output stage of solar microinverters or UPS inverters converting DC to 50/60Hz AC. IC Role / Device Role / Timing Role: Low-loss freewheeling and commutation path for H-bridge or half-bridge topologies. Use Value: 90°C/W RθJA (FR-4) and 3°C/W RθJC allow direct mounting to aluminum chassis for passive cooling in fanless systems. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SS1240S-13 | Same 40V/12A rating, but SMB package; RθJC = 10°C/W (vs. 3°C/W); VF = 0.55V @ 6A/25°C. | Limited to lower ambient temps due to higher thermal resistance; unsuitable for sealed enclosures above 70°C. | Select when footprint compatibility with legacy SMB layouts is required and thermal margin exceeds 15°C. |
| MBR1240CTG | TO-220AB package; 40V/12A; VF = 0.58V @ 6A/25°C; requires mechanical mounting and heatsink. | Higher profile and assembly cost; better for high-reliability industrial power supplies with forced air. | Choose when long-term reliability under sustained 12A load outweighs size and soldering complexity constraints. |
Compared with SS1240S-13 and MBR1240CTG, PDS1240CTL-13 delivers superior thermal performance in ultra-thin form factor, enabling 12A operation without heatsink in space-constrained DC-DC modules and portable power adapters.

FAQ
What is the maximum continuous current per leg at 100°C ambient?
At TA = 100°C with 2"×2" aluminum PCB (Note 7), the derated IO per leg is approximately 4.2A, based on Figure 3's "Note 7 (Per Leg)" curve. Total device rating remains 12A only when both legs share thermal mass and operate below 75°C ambient with adequate copper area.
Can PDS1240CTL-13 replace a single 12A Schottky in a center-tap transformer design?
No - it contains two independent anodes sharing one cathode, making it unsuitable for center-tap configurations requiring separate cathodes. It is designed for dual-input ORing or parallel anode routing, not center-tapped full-wave rectification.
Is the PowerDI5 package compatible with standard reflow profiles for lead-free soldering?
Yes - its matte tin annealed terminals meet MIL-STD-202 Method 208 and are qualified for JEDEC J-STD-020 Level 1 moisture sensitivity. Standard Pb-free reflow profiles (peak 260°C, 60s max above 217°C) are fully supported without preconditioning.
Does the guard ring construction affect reverse recovery time?
As a Schottky diode, PDS1240CTL-13 has no minority-carrier storage and therefore no defined reverse recovery time (trr). The guard ring improves voltage standoff uniformity but does not introduce recovery delay - it maintains true majority-carrier behavior essential for high-frequency switching.
