Product details
Overview
SFA1004GH from Taiwan Semiconductor is a 10A, 200V super fast recovery rectifier diode in TO-220AC package, optimized for high-efficiency DC/DC converters and switching inverters. It delivers VF = 0.975 V at IF = 10 A and TJ = 25°C, trr = 35 ns, IR ≤ 10 µA at VR = 200 V and TJ = 25°C, and RθJC = 3.5 °C/W - enabling compact thermal design in automotive-grade power supplies.
For engineers reviewing the SFA1004GH datasheet, SFA1004GH pinout, SFA1004GH application, or SFA1004GH equivalent, key selection criteria include its AEC-Q101 qualification, 200 V VRRM rating, low forward voltage drop, fast 35 ns reverse recovery time, and TO-220AC mechanical compatibility with standard heatsink mounting.
Technical Context
This super fast rectifier uses a single-die planar junction structure optimized for minimal charge storage and rapid carrier recombination. Its 35 ns trr and low CJ (70 pF at 1 MHz, VR = 4 V) support high-frequency switching up to several hundred kHz in hard-switched topologies.
The device operates across -55°C to +150°C junction temperature range with 125 A IFSM surge capability and meets JESD201 Class 2 whisker resistance. Its matte tin-plated leads comply with J-STD-002 solderability and UL 94V-0 molding compound ensures flame-retardant reliability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - maximum repetitive reverse blocking voltage; defines usable input voltage headroom in boost/flyback designs |
| IF | 10 A - continuous forward current rating at TC = 100°C; sets steady-state conduction capacity |
| VF | 0.975 V @ IF = 10 A, TJ = 25°C - directly determines conduction loss and thermal load in high-duty-cycle operation |
| trr | 35 ns - enables efficient operation in 100–500 kHz SMPS without excessive switching loss or EMI |
| RθJC | 3.5 °C/W - allows direct thermal interface to heatsinks; supports >10 W dissipation with <35°C rise at 10 A |
| IR | ≤10 µA @ VR = 200 V, TJ = 25°C - ensures low leakage in high-impedance bias networks and standby modes |
Pinout & Package
Package: TO-220AC - three-terminal, through-hole, single-diode configuration with isolated tab (cathode-connected tab). Mounting torque ≤ 0.56 N·m; polarity marked on case.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry terminal | Connected to lower-potential side (e.g., switch node in synchronous rectification or cathode of preceding stage) |
| Cathode | Forward current exit / reverse blocking terminal | Electrically tied to metal tab; must be insulated from chassis unless referenced to system ground |
| Tab (Case) | Thermal path + Cathode connection | Provides primary heat conduction path; electrically identical to cathode - requires insulating washer if mounted to grounded heatsink |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive powertrain and body electronics per stress test requirements (HTOL, TCT, HTRB, etc.) |
| Super fast recovery (trr = 35 ns) | Reduces switching loss and ringing in high-frequency converters; avoids cross-conduction in synchronous topologies |
| Low VF (0.975 V @ 10 A) | Lowers conduction loss by ~15–20% vs. standard FRDs; improves full-load efficiency in 12 V–48 V output stages |
| TO-220AC with isolated tab | Enables direct heatsinking while maintaining electrical isolation; simplifies mechanical layout vs. insulated packages |
| Halogen-free & RoHS compliant | Meets IEC 61249-2-21 and EU RoHS Directive 2011/65/EU for environmentally constrained applications |

Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH10L06TV1 | VRRM = 600 V, VF = 1.05 V @ 10 A, trr = 30 ns, TO-220AC | Higher voltage rating but higher VF; suited for 400 V+ bus systems | Select when >300 V reverse blocking is required; verify thermal margin due to +0.075 V VF increase |
| ON Semi MUR1020CT | Dual common-cathode configuration, VRRM = 200 V per diode, VF = 0.92 V @ 10 A, trr = 35 ns, TO-220AB | Requires dual-layout routing; tab is isolated but not cathode-connected | Choose only if dual-diode topology is needed; note TO-220AB pinout differs - anode1/anode2/tab vs. SFA1004GH's anode/cathode/tab |
Compared with STTH10L06TV1 and MUR1020CT, the SFA1004GH offers optimal balance of 200 V rating, lowest VF in its class, AEC-Q101 compliance, and cathode-tied tab for simplified heatsink grounding - making it preferred for cost-sensitive, thermally constrained automotive and industrial 200 V rectification.

FAQ
Is SFA1004GH AEC-Q101 qualified?
Yes, the "H" suffix in SFA1004GH explicitly denotes AEC-Q101 qualification per Version K2103 documentation. This includes stress testing for high-temperature operating life, temperature cycling, and highly accelerated stress testing - confirming suitability for automotive power electronics where reliability under thermal and vibration stress is critical. The SFA1004GH meets all AEC-Q101 requirements as verified by Taiwan Semiconductor's certification records.
What is the maximum junction temperature for SFA1004GH?
The SFA1004GH has a maximum junction temperature (TJ MAX) of +150°C, as specified in the Absolute Maximum Ratings table. This rating applies across the full operating range and supports reliable operation in high-ambient environments such as engine compartments or enclosed industrial enclosures - provided thermal design maintains junction temperature below this limit using the documented RθJC = 3.5 °C/W path.
Does SFA1004GH have a cathode-connected tab?
Yes, the metal tab on the SFA1004GH is electrically connected to the cathode terminal, as confirmed by the marking diagram and mechanical data. This configuration requires electrical isolation (e.g., mica washer or silicone pad) when mounting to a grounded heatsink. The TO-220AC package pinout is Anode–Cathode–Tab (cathode), distinct from TO-220AB's isolated-tab layout.
What is the reverse recovery time (trr) of SFA1004GH and how is it measured?
The SFA1004GH has a typical reverse recovery time (trr) of 35 ns, measured under conditions IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A, per the Electrical Specifications table. This value reflects performance in high-frequency switching applications and is validated using standardized double-pulse test circuits shown in Figure 6 of the datasheet - ensuring consistency with industry measurement practices for super fast rectifiers.
Can SFA1004GH replace SFA1004G in existing designs?
Yes, the SFA1004GH is a direct replacement for SFA1004G in terms of electrical parameters, thermal performance, and mechanical footprint - the only difference is AEC-Q101 qualification indicated by the "H" suffix. No PCB or thermal redesign is needed; however, users should confirm that their application requires or benefits from automotive-grade reliability validation before migration.
