Product details
Overview
SFA1005G from Taiwan Semiconductor is a 300 V, 10 A super fast recovery rectifier diode in TO-220AC package, featuring 35 ns reverse recovery time, 1.300 V forward voltage at 10 A/25°C, and 50 pF junction capacitance - used in high-frequency DC-DC converters and freewheeling paths.
For engineers reviewing the SFA1005G datasheet, SFA1005G pinout, SFA1005G application, or SFA1005G equivalent, key selection criteria include peak reverse voltage (300 V), surge current rating (125 A), thermal resistance (3.5 °C/W), AEC-Q101 qualification status, and TO-220AC mechanical compatibility for heatsink mounting.
Technical Context
This super fast rectifier employs a single-die silicon PN junction optimized for low conduction loss and rapid carrier recombination. Its 35 ns trr enables operation in switching-mode power supplies above 100 kHz without excessive switching loss.
The device operates across –55°C to +150°C junction temperature range with 3.5 °C/W junction-to-case thermal resistance, supporting stable performance under continuous 10 A forward current and transient 125 A surge conditions per JESD201 Class 2 whisker-tested matte tin leads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 300 V - maximum repetitive reverse voltage; defines safe blocking capability in DC-DC flyback or boost stages |
| IF | 10 A - continuous average forward current; supports sustained output delivery in industrial SMPS |
| IFSM | 125 A - non-repetitive surge rating; handles inrush and fault transients without failure |
| trr | 35 ns - reverse recovery time; minimizes switching loss and EMI in >100 kHz converters |
| VF | 1.300 V @ 10 A, 25°C - forward voltage drop; determines conduction loss and thermal load at rated current |
| RθJC | 3.5 °C/W - junction-to-case thermal resistance; enables direct heatsink mounting for thermal management |
| CJ | 50 pF @ 1 MHz, 4 V - junction capacitance; impacts high-frequency switching node ringing and snubber design |

Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH10R03G (STMicroelectronics) | Same 300 V VRRM, 10 A IF, but trr = 45 ns and VF = 1.35 V @ 10 A | Higher trr increases switching loss in >120 kHz designs; slightly higher VF raises conduction loss | Select when legacy ST ecosystem alignment or dual-sourcing is required; verify thermal margin with RθJC = 4.0 °C/W |
| VS-10EWH03-M3 (Vishay) | Identical 300 V/10 A rating, trr = 35 ns, VF = 1.30 V, but TO-220AC package with isolated tab | Electrically isolated tab allows floating cathode configurations not possible with SFA1005G's case-tied cathode | Choose when circuit requires cathode isolation from heatsink ground; note different mounting torque spec (0.50 N·m) |
Compared with STTH10R03G and VS-10EWH03-M3, the SFA1005G offers identical trr and competitive VF while using a cost-optimized, cathode-tied TO-220AC package - ideal for grounded-cathode SMPS outputs where isolation is unnecessary and thermal coupling is prioritized.

FAQ
What is the maximum junction temperature rating for the SFA1005G?
The SFA1005G has a maximum junction temperature (TJ MAX) of +150°C, verified across its full operating range from –55°C to +150°C. This rating supports reliable operation in enclosed industrial power supplies and automotive under-hood environments when mounted on an appropriately sized heatsink with thermal interface material. Derating curves in the datasheet define allowable current reduction above 100°C ambient.
Is the SFA1005G pin-compatible with other devices in the SFA100xG series?
Yes, all SFA1001G through SFA1008G share identical TO-220AC packaging, pinout, and mechanical dimensions - including anode (lead 1), cathode (lead 2), and case-connected tab (lead 3). This allows direct substitution within the same voltage class when board layout accommodates the target VRRM requirement, provided thermal and electrical margins are validated.
Does the SFA1005G meet AEC-Q101 reliability standards?
The base SFA1005G is not AEC-Q101 qualified; however, the variant SFA1005GH is fully AEC-Q101 certified for automotive applications. Both share identical electrical parameters and package, but only the 'H' suffix version undergoes stress testing per AEC-Q101 Rev D, including HTGB, TCT, and ESD requirements. Always specify SFA1005GH for automotive use cases.
What is the typical junction capacitance of the SFA1005G and how does it affect circuit design?
The SFA1005G exhibits 50 pF typical junction capacitance (CJ) measured at 1 MHz and 4.0 V reverse bias. This value influences high-frequency switching node behavior - particularly in resonant topologies - and informs snubber network sizing. Lower CJ than SFA1001G–SFA1004G (70 pF) reduces capacitive coupling and EMI generation in 300–600 V designs.
How does the forward voltage of the SFA1005G compare to lower-voltage variants in the same family?
The SFA1005G has a typical VF of 1.300 V at 10 A and 25°C - higher than SFA1001G–SFA1004G (0.975 V) due to increased drift region resistance needed for 300 V blocking. This trade-off ensures optimal balance between breakdown voltage and conduction loss; actual VF rises to ~1.45 V at 100°C junction temperature, requiring thermal design validation for sustained 10 A loads.
