Product details
Overview
FERD30L60CTS from STMicroelectronics is a 60 V field-effect rectifier diode in TO-220AB package, optimized for high-efficiency, thermally constrained AC/DC adapters and USB-PD chargers. It delivers 30 A total average forward current (2 × 15 A dual-diode configuration), 0.37 V typical forward voltage at 3 A/25 °C, <820 µA reverse leakage at 60 V/25 °C, and 150 °C maximum junction temperature.
For engineers reviewing the FERD30L60CTS datasheet, FERD30L60CTS pinout, FERD30L60CTS application, or FERD30L60CTS equivalent, key selection criteria include conduction loss modeling (P = 0.27×IF(AV) + 0.02×IF²(RMS)), thermal resistance (Rth(j-c) = 0.9 °C/W total), and stable IR vs. VR behavior across -65 to +175 °C storage range.
Technical Context
This device employs ST's proprietary field-effect rectifier process-distinct from conventional Schottky or PN diodes-to achieve superior VF/IR trade-off on fixed silicon area. Its dual-diode structure enables center-tap full-wave rectification without external paralleling.
Thermal design is enabled by low Rth(j-c) (0.9 °C/W total) and defined mounting torque (0.55 N·m recommended for TO-220AB). The device avoids thermal runaway under (dPtot/dTj) < (1/Rth(j-a)) condition when heatsinked per spec.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - Maximum repetitive reverse blocking voltage; defines safe operating limit in flyback/clamp circuits |
| IF(AV) | 30 A total (2 × 15 A) - Continuous DC output capability per diode leg in dual configuration |
| VF (typ.) | 0.37 V @ 3 A, 25 °C - Enables sub-0.5 W conduction loss per diode at mid-load in 5–20 W adapters |
| IR (max) | 60 mA @ 125 °C, VRRM - Low leakage preserves efficiency in high-temp, high-density charger PCBs |
| Rth(j-c) | 0.9 °C/W total - Allows direct heatsink mounting with predictable thermal margin up to 150 °C Tj |
| Tj (max) | +150 °C - Supports operation in sealed enclosures without forced airflow |
Pinout & Package
TO-220AB package with isolated tab (K), three terminals: Anode 1 (A1), Cathode (K), Anode 2 (A2). Tab is electrically connected to cathode (K) and serves as primary thermal path.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | Anode of Diode 1 | Input node for first half-cycle rectification; rated for 15 A avg. forward current |
| K | Cathode (common) & Thermal Tab | Shared cathode output and mechanical/thermal interface; must be electrically isolated from PCB ground unless referenced |
| A2 | Anode of Diode 2 | Input node for second half-cycle; enables center-tapped transformer full-wave rectification |
Key Features
| Feature | Design Value |
|---|---|
| ST advanced rectifier process | Proprietary silicon technology delivering best-in-class VF/IR balance-0.37 V VF and <820 µA IR simultaneously at 60 V rating |
| Stable leakage over reverse voltage | IR remains ≤60 mA up to VRRM at 125 °C-enables reliable hold-up time in compact offline SMPS |
| Low forward voltage drop | 0.49 V max @ 15 A/25 °C-reduces conduction loss by ~30% vs. standard fast recovery diodes in 12–24 V output rails |
| High frequency operation | No reverse recovery charge (Qrr ≈ 0); supports >100 kHz switching without snubbers in LLC or QR flyback designs |
Applications
| USB-PD Wall Adapters | Industrial AC/DC Power Supplies |
|---|---|
Use Scenario: 65 W compact wall adapter with GaN HEMT primary and synchronous secondary. IC Role / Device Role / Timing Role: Dual-anode field-effect rectifier replacing two discrete Schottkys in center-tap secondary winding. Use Value: Reduces secondary-side conduction loss by 0.8 W total and eliminates reverse recovery losses-enabling >94% efficiency at full load. | Use Scenario: DIN-rail mounted 48 V/20 A industrial power supply with natural convection cooling. IC Role / Device Role / Timing Role: Output rectifier in dual-phase forward converter with shared cathode return path. Use Value: Maintains Tj ≤135 °C at 55 °C ambient using only 25 cm² copper pour-no heatsink required. |
| Automotive On-Board Chargers (OBC) | Server PSU Auxiliary Rails |
Use Scenario: Bidirectional OBC with 3.3 kW AC/DC stage operating at 100 kHz. IC Role / Device Role / Timing Role: Secondary-side rectifier in phase-shifted full-bridge topology with soft-switching. Use Value: Zero Qrr prevents voltage spikes during ZVS transitions-eliminates need for RC snubbers on secondary side. | Use Scenario: 12 V standby rail in 3 kW server PSU with multi-phase buck converter. IC Role / Device Role / Timing Role: High-current auxiliary rectifier handling peak loads up to 30 A pulsed. Use Value: Withstands 250 A non-repetitive surge (tp = 10 ms) without degradation-ensures robustness during cold-start sequencing. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar field-effect rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH30L06CW | 60 V, 30 A fast recovery diode; VF = 1.05 V typ., Qrr = 65 nC | Higher conduction loss, requires snubber in >50 kHz designs | Preferred where cost sensitivity outweighs efficiency targets and thermal budget allows higher VF |
| MBR30L60CT | 60 V, 30 A Schottky; VF = 0.55 V typ., IR = 1.2 mA @ 125 °C | Lower VF but limited to ≤125 °C Tj; unsuitable for 150 °C environments | Valid for lower-temperature, lower-cost consumer adapters-but not for automotive or industrial derating |
Compared with STTH30L06CW and MBR30L60CT, FERD30L60CTS uniquely combines 150 °C operation, near-zero Qrr, and sub-0.4 V VF-making it the only choice for thermally dense, high-frequency, high-reliability adapter and OBC designs.

FAQ
Is FERD30L60CTS a Schottky diode?
No. FERD30L60CTS is a field-effect rectifier diode based on ST's proprietary silicon process-not a metal-semiconductor Schottky structure. It achieves lower forward voltage than fast recovery diodes and higher temperature rating than Schottkys, with near-zero reverse recovery charge (Qrr).
What is the thermal pad connection requirement for TO-220AB mounting?
The TO-220AB tab (K terminal) is electrically connected to the cathode and must be mounted to a heatsink using thermal compound and torque-controlled fastening. Recommended torque is 0.55 N·m; maximum is 0.6 N·m. Electrical isolation from PCB ground is required unless circuit topology references cathode to system ground.
Can FERD30L60CTS replace two separate 15 A Schottky diodes?
Yes-its dual-anode (A1/A2), common-cathode (K) configuration is designed for direct replacement of two discrete 15 A Schottkys in center-tapped transformer topologies. Pinout matches industry-standard dual-diode TO-220 packages, and thermal performance exceeds parallel discrete solutions due to matched die characteristics and shared thermal path.
Does FERD30L60CTS require a snubber circuit in high-frequency operation?
No. Due to negligible reverse recovery charge (Qrr ≈ 0), FERD30L60CTS does not generate voltage spikes during turn-off, eliminating the need for RC snubbers in LLC resonant, QR flyback, or phase-shifted full-bridge converters operating up to 500 kHz.
