Product details
Overview
FERD40L60CG-TR from STMicroelectronics is a 60 V field-effect rectifier diode in D²PAK package, optimized for high-efficiency, thermally constrained AC/DC adapters and USB-PD chargers. It delivers typ. 0.375 V forward voltage at 20 A (Tj = 125 °C), 40 A total average forward current (dual-diode configuration), and stable 40 mA max reverse leakage at 125 °C / VRRM.
For engineers reviewing the FERD40L60CG-TR datasheet, FERD40L60CG-TR pinout, FERD40L60CG-TR application, or FERD40L60CG-TR equivalent, key selection criteria include VF/IR trade-off at elevated junction temperature, thermal resistance (Rth(j-c) = 0.8 °C/W device-level), and D²PAK footprint compatibility with high-power density board layouts.
Technical Context
This dual-diode rectifier uses ST's proprietary field-effect process to suppress minority-carrier injection, enabling ultra-low forward voltage without sacrificing reverse leakage stability. Its architecture eliminates recovery tail charge, supporting >1 MHz switching in quasi-resonant and active-clamp flyback topologies.
Thermal design is enabled by low Rth(j-c) (0.8 °C/W) and defined mounting torque (0.55 N·m) on the exposed drain tab. The device operates up to 150 °C junction temperature with validated derating curves for ambient temperatures up to 125 °C at full 40 A rating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - Maximum repetitive reverse blocking voltage; defines safe operating range in secondary-side rectification of ≤24 V output supplies. |
| IF(AV) | 40 A - Total average forward current (2 × 20 A per diode); supports high-current USB-C PD 3.1 100 W adapter designs. |
| VF (typ.) | 0.375 V @ 20 A, 125 °C - Low conduction loss enables ≥95% efficiency in 65–100 W adapters at full load and high ambient. |
| IR (max) | 80 mA @ 125 °C, VRRM - Stable leakage ensures minimal standby power loss and no thermal runaway risk under hot-swap conditions. |
| Rth(j-c) | 0.8 °C/W - Device-level junction-to-case thermal resistance; allows direct heatsink mounting for compact thermal management. |
| Tj (max) | +150 °C - Maximum junction temperature; enables operation in sealed enclosures with limited airflow (e.g., wall-mounted chargers). |
Pinout & Package
Package: D²PAK (TO-263AB), surface-mount, single-row 3-terminal outline with exposed drain tab for thermal conduction. Mounting requires 0.55 N·m torque on M3 screw (if used with heatsink).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Source) | Anode connection (per diode) | Electrically isolated anode terminal; two independent anodes enable dual-output or center-tap rectification. |
| Pin 2 (Drain Tab) | Cathode (common) | Exposed metal tab serves as common cathode and primary thermal path; must be soldered to PCB copper pour or heatsink. |
| Pin 3 (Source) | Anode connection (per diode) | Second independent anode; enables synchronous or interleaved rectifier configurations without external isolation. |
Key Features
| Feature | Design Value |
|---|---|
| Field-effect rectifier topology | Eliminates reverse recovery charge (Qrr ≈ 0), removing EMI spikes and enabling >1 MHz operation without snubbers. |
| VF/IR optimization | 0.375 V @ 20 A / 125 °C and 80 mA IR @ VRRM / 125 °C - achieves best-in-class trade-off for 60 V class in space-constrained adapters. |
| Dual-diode integration | Two matched 20 A diodes in one D²PAK - reduces PCB area by 40% vs. discrete TO-220 solutions and improves thermal coupling. |
| ECOPACK® compliant | Halogen-free, RoHS-compliant epoxy; meets UL94 V0 flammability rating for consumer end-equipment safety certification. |
Applications
| USB-C PD 100 W Adapter | Industrial 24 V DC Power Supply |
|---|---|

IC Role / Device Role / Timing Role: High-current, low-VF dual rectifier handling continuous 40 A average current with shared thermal path. Use Value: Enables 2-layer PCB layout with 120 mm² copper pour under tab; maintains Tj < 135 °C at full load and 60 °C ambient. |
| Laptop AC Adapter (65 W) | USB-A + USB-C Dual-Port Charger |

Use Value: Eliminates need for two discrete diodes and associated layout complexity; maintains ±1.5% cross-regulation across loads. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar field-effect rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| FERD40L60CTS | Same die, TO-220AB package; Rth(j-c) = 1.3 °C/W per diode (2.6 °C/W device), higher mounting torque (0.55 N·m), through-hole assembly. | Requires heatsink mounting and wave soldering; unsuitable for high-density SMT lines. | Select for prototyping, lower-volume industrial supplies where manual assembly or heatsink clamping is preferred. |
| STTH30L06CW | 60 V, 30 A dual Schottky; VF = 0.55 V @ 15 A/125 °C; Qrr > 0; Rth(j-c) = 1.0 °C/W device. | Higher conduction loss and EMI from recovery; requires snubber network and larger heatsink. | Select only if legacy Schottky qualification exists and field-effect rectifier requalification is not feasible. |
Compared with FERD40L60CG-TR, the TO-220AB variant trades SMT scalability for easier thermal testing, while the Schottky alternative increases system-level BOM cost and EMI filter size due to recovery losses - making the D²PAK field-effect rectifier optimal for volume production of compact, high-efficiency adapters.

FAQ
What is the maximum allowable case temperature for FERD40L60CG-TR during operation?
The device has a maximum junction temperature of +150 °C and a junction-to-case thermal resistance of 0.8 °C/W. With typical PCB copper area (≥1000 mm²), case temperature remains ≤110 °C at 40 A IF(AV) and 60 °C ambient. Derating curves in Figure 1 confirm 20 A per diode is sustainable at TC = 130 °C.
Can FERD40L60CG-TR be used in place of a standard Schottky diode without circuit modification?
Yes - it is a drop-in replacement for 60 V dual Schottky diodes in D²PAK (e.g., STTH30L06CW) with identical pinout and polarity. No gate drive or timing changes are needed; however, snubber networks can be removed due to zero Qrr, reducing component count and EMI filtering requirements.
How does the dual-diode structure impact PCB layout and thermal management?
The dual-anode/single-cathode configuration allows independent anode routing for dual-output supplies while sharing one thermal pad. The exposed drain tab must be soldered to ≥1000 mm² of 2 oz copper with thermal vias to internal planes; this configuration reduces thermal resistance by 35% versus two discrete D²PAKs and avoids thermal imbalance between channels.
Is FERD40L60CG-TR qualified for automotive applications?
No - it is specified for industrial and consumer power supplies only. It lacks AEC-Q101 qualification, automotive-grade screening, and extended temperature validation beyond 150 °C junction. For automotive 12 V/24 V DC-DC converters, ST recommends the AEC-Q101-qualified STTH30L06TV1.
