Product details
Overview
SF13GHR0G from Taiwan Semiconductor is a 150 V, 1 A super fast rectifier diode in DO-204AL (DO-41) package, featuring 35 ns reverse recovery time, 0.95 V forward voltage at 1 A/25°C, and AEC-Q101 qualification for automotive-grade reliability. It serves as a freewheeling or output rectifier in DC-DC converters and switching inverters where low conduction loss and fast switching are required.
For engineers reviewing the SF13GHR0G datasheet, SF13GHR0G pinout, SF13GHR0G application, or SF13GHR0G equivalent, key selection criteria include its 150 V repetitive peak reverse voltage, 30 A surge rating, junction-to-lead thermal resistance of 20 °C/W, AEC-Q101 qualification status, and DO-41 mechanical compatibility with standard through-hole PCB layouts.
Technical Context
The SF13GHR0G is a single-die, planar-junction silicon rectifier optimized for high-speed switching operation. Its 35 ns reverse recovery time and low 0.95 V forward voltage at rated current enable reduced switching losses in high-frequency power supplies.
Designed for automotive and industrial environments, it supports continuous operation up to +150°C junction temperature and meets JESD201 Class 2 whisker resistance and RoHS/halogen-free requirements per IEC 61249-2-21.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| VRRM | 150 V - Maximum repetitive reverse blocking voltage; defines safe operating range in flyback or boost topologies |
| IF | 1 A - Continuous average forward current; sets thermal design baseline for heatsinking and trace width |
| IFSM | 30 A - Non-repetitive surge current handling; enables robustness against startup inrush or load transients |
| VF @ 1A, 25°C | 0.95 V - Low conduction loss directly reduces power dissipation and improves efficiency at nominal load |
| trr | 35 ns - Fast reverse recovery minimizes switching losses and EMI generation in >100 kHz converters |
| RθJL | 20 °C/W - Junction-to-lead thermal resistance; enables direct solder-pad thermal path estimation for PCB layout |
| TJ max | +150 °C - Maximum junction temperature rating; supports operation in under-hood or enclosed industrial enclosures |
Pinout & Package
Package: DO-204AL (DO-41), axial leaded, epoxy-molded case with cathode band polarity marking. Weight: ~0.350 g. Leads are pure tin plated, solderable per J-STD-002.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Forward current entry point | Connected to lower-potential node (e.g., switch node in buck converter); requires adequate copper area for thermal conduction |
| Cathode (Lead 2, banded end) | Forward current exit / reverse blocking terminal | Connected to output rail or ground return; cathode band must align with PCB silkscreen polarity indicator |
Key Features

| Super fast recovery (trr = 35 ns) | Enables use in high-frequency SMPS (>200 kHz) without excessive switching loss or ringing |
| Low VF (0.95 V @ 1A) | Reduces conduction loss by ~15% vs. standard fast rectifiers, improving system efficiency at light-to-moderate loads |
| RoHS & halogen-free | Complies with IEC 61249-2-21 and global environmental regulations for industrial and automotive manufacturing |
| Junction-to-lead RθJL = 20 °C/W | Supports direct thermal coupling to copper pour or chassis, enabling compact thermal design without external heatsink |
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 |
|---|---|---|---|
| STTH1R06U | Same 1 A / 600 V rating but 50 ns trr; VF = 1.15 V @ 1A; TO-220AC package | Higher voltage margin (600 V) suits universal-input PFC stages; larger package requires different mounting and thermal design | Select when >300 V reverse stress or higher surge immunity is required; not drop-in due to TO-220 footprint |
| ES1D-E3/54 | 1 A / 200 V; trr = 35 ns; VF = 0.93 V; DO-204AL package; no AEC-Q101 | Matches SF13GHR0G's speed and package but lacks automotive qualification and has lower VRRM | Acceptable for cost-sensitive industrial or consumer designs where AEC-Q101 is not mandated |
Compared with STTH1R06U and ES1D-E3/54, the SF13GHR0G uniquely combines AEC-Q101 qualification, 150 V VRRM, 35 ns trr, and DO-41 packaging-making it optimal for space-constrained automotive auxiliary supplies where reliability and thermal performance are prioritized over ultra-high voltage margin.

FAQ
What does the "H" suffix in SF13GHR0G signify?
The "H" in SF13GHR0G indicates AEC-Q101 qualification-verified through accelerated stress testing including HTSL, TC, and UHAST. This confirms SF13GHR0G meets automotive-grade reliability requirements for under-hood and body electronics applications, unlike non-H variants such as SF13G.
Is SF13GHR0G pin-compatible with other DO-41 rectifiers like 1N4007?
Yes, SF13GHR0G uses the standard DO-204AL (DO-41) package with axial leads and cathode band marking, making it mechanically interchangeable with 1N4007 and similar diodes. However, SF13GHR0G offers significantly faster recovery (35 ns vs. >2 µs) and lower VF, so electrical behavior differs in high-frequency circuits.
What is the maximum allowable ambient temperature for SF13GHR0G at 1 A continuous current?
At 1 A continuous forward current, SF13GHR0G can operate up to ~75°C ambient temperature with standard PCB copper (1 in² 2 oz Cu) due to its RθJA of 80 °C/W. For higher ambient conditions, derating per the forward current derating curve (Fig.1) or enhanced thermal layout is required to maintain TJ ≤ 150°C.
Does SF13GHR0G support reflow soldering?
No-SF13GHR0G is specified for wave or hand soldering only. Its DO-41 package and epoxy molding compound are not rated for lead-free reflow profiles (peak >260°C). Reflow may cause internal delamination or lead detachment; IPC-J-STD-002-compliant tin-plated leads require wave or selective soldering processes.
How does the 20 °C/W RθJL value impact thermal design?
The 20 °C/W junction-to-lead thermal resistance means that for every watt of power dissipated (e.g., 0.95 W at 1 A × 0.95 V), the junction rises 20°C above the lead temperature. This enables accurate thermal modeling when leads are thermally anchored to large copper planes or chassis, reducing reliance on board-level RθJA (80 °C/W).
