Product details
Overview
FERD30H100SB-TR from STMicroelectronics is a 100 V field-effect rectifier diode in DPAK package, rated for 30 A average forward current, 0.405 V max forward voltage at 30 A/125 °C, and 130 µA max reverse leakage at 25 °C/VRRM. It replaces Schottky diodes in high-efficiency, thermally constrained AC/DC front-ends and switch-mode power supplies.
For engineers reviewing the FERD30H100SB-TR datasheet, FERD30H100SB-TR pinout, FERD30H100SB-TR application, or FERD30H100SB-TR equivalent, key selection criteria include its VF/IR trade-off stability over temperature, junction-to-case thermal resistance of 0.9 °C/W, ECOPACK®2 compliance, and suitability for confined-casing 100 V rectification where thermal runaway risk must be minimized.
Technical Context
This device uses ST's proprietary field-effect rectifier process to decouple forward voltage (VF) and reverse leakage (IR) dependencies on temperature-reducing thermal runaway risk versus conventional Schottky diodes. Its VF remains ≤0.745 V at 30 A/125 °C, while IR stays ≤16 mA at 125 °C/VRRM.
Designed for high-frequency operation, it exhibits low junction capacitance (typ. 1000 pF at 0 V, 1 MHz), enabling use in PFC stages and resonant converters up to several hundred kHz. The DPAK package supports conduction cooling with verified thermal impedance performance across copper pad areas from 0 to 100 cm².
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse blocking voltage; defines safe operating limit in bridge or flyback snubber circuits. |
| IF(AV) | 30 A - Average forward current at TC = 145 °C; sets continuous conduction capability in high-power rectifiers. |
| VF (max) | 0.405 V at 30 A / 125 °C - Low conduction loss enables >98% efficiency in 100 V output rails with minimal heatsink requirement. |
| IR (max) | 130 µA at 25 °C / VRRM - Ultra-low leakage preserves standby power budget in energy-efficient adapters. |
| Tj(max) | 175 °C - Enables operation in high-ambient environments (e.g., enclosed industrial PSUs) without derating penalties. |
| Rth(j–c) | 0.9 °C/W - Confirmed thermal path from junction to case; allows accurate heatsink sizing using standard conduction models. |
| Package | DPAK - Surface-mount, thermally enhanced outline with exposed drain tab; compatible with automated reflow and wave soldering. |
Pinout & Package
The FERD30H100SB-TR is a 3-terminal DPAK device: Anode (A), Cathode (K), and Drain (D) - where the Drain is internally tied to the cathode and forms the electrically active thermal pad. The package features an exposed metal tab (Drain) for direct PCB thermal coupling.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Input terminal for forward conduction | Connected to AC input or switching node; carries full load current during conduction phase. |
| Cathode (K) | Output terminal for forward conduction | Connected to DC bus or output capacitor; serves as common reference for gate drivers in synchronous designs. |
| Drain (D) / Tab | Thermal and electrical connection to cathode | Must be soldered to large copper pour for thermal management; electrically identical to cathode; no isolation required. |
Key Features
| Feature | Design Value |
|---|---|
| ST advanced rectifier process | Enables VF/IR optimization unattainable with standard Schottky or PN processes-verified by 0.405 V/30 A and 130 µA specs. |
| Stable leakage vs. temperature | IR increases only 123× (130 µA → 16 mA) from 25 °C to 125 °C-vs. >1000× for typical Schottkys-reducing thermal runaway probability. |
| Low VF at high Tj | 0.745 V max at 30 A/125 °C ensures <10 W conduction loss in 1 kW PFC stage, minimizing heatsink volume. |
| ECOPACK®2 compliance | Halogen-free, RoHS-compliant epoxy meets UL94 V0 flammability rating-validates use in safety-certified end equipment. |
| High-frequency capability | Junction capacitance ≤1000 pF at 0 V enables clean turn-off in 300–500 kHz LLC resonant converters without excessive ringing. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-efficiency 100 V rectification applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH30L06CW | 60 V VRRM, 30 A IF(AV), 0.95 V VF (max) at 30 A/125 °C - higher VF, lower voltage rating. | Only suitable for ≤60 V systems; cannot replace in 100 V PFC or telecom rectifiers. | Select only if system VRRM margin is <65 V and thermal design tolerates +5.5 W extra loss. |
| Vishay VS-30CPH06-M3 | 60 V VRRM, 30 A IF(AV), 0.62 V VF (typ) at 30 A/125 °C - lower VF than STTH30L06CW but still 50% higher than FERD30H100SB-TR. | Limited to 60 V applications; lacks documented thermal stability data across 25–125 °C. | Acceptable only in cost-sensitive 60 V designs where 0.22 V higher VF is acceptable and thermal runaway risk is mitigated externally. |
Compared with STTH30L06CW and VS-30CPH06-M3, FERD30H100SB-TR uniquely delivers 100 V blocking with sub-0.41 V VF at full load and 125 °C-enabling smaller heatsinks, higher power density, and elimination of forced air cooling in 100 V systems.

FAQ
What is the maximum allowable case temperature for continuous operation?
The device is rated for IF(AV) = 30 A at TC = 145 °C per datasheet Table 2. Operation above this temperature requires linear derating per Figure 1; at TC = 160 °C, IF(AV) drops to ~22 A. Exceeding 175 °C junction temperature violates absolute maximum ratings and risks permanent failure.
Can FERD30H100SB-TR be used as a drop-in replacement for Schottky diodes in existing designs?
No direct drop-in replacement is guaranteed: although pin-compatible in DPAK, its cathode-connected drain tab requires matching PCB thermal pad layout. Also, its lower VF reduces conduction loss but may alter snubber timing or control loop dynamics-validation under worst-case load and temperature is mandatory.
Is the DPAK variant lead-free and RoHS compliant?
Yes. FERD30H100SB-TR is manufactured in an ECOPACK®2-compliant process: halogen-free, lead-free, and fully RoHS 2011/65/EU compliant. The "-TR" suffix confirms tape-and-reel packaging with moisture sensitivity level (MSL) 1 rating for standard SMT handling.
How does its thermal resistance compare between DPAK and TO-220AB variants?
Rth(j–c) is identical (0.9 °C/W) for both DPAK (FERD30H100SB-TR) and TO-220AB (FERD30H100STS) packages per Table 3. However, DPAK relies on PCB copper area for heat spreading, while TO-220AB uses bolted heatsinks-making DPAK more sensitive to PCB layout but eliminating mechanical assembly steps.
