Product details
Overview
SFT14G A0G from Taiwan Semiconductor is a 1 A, 200 V repetitive peak reverse voltage super fast rectifier diode in TS-1 package, featuring 35 ns reverse recovery time, 0.95 V forward voltage at 1 A and 25°C, and 20 pF junction capacitance at 1 MHz/4.0 V - used in DC-DC converters and freewheeling paths where low conduction loss and fast switching are required.
For engineers reviewing the SFT14G A0G datasheet, SFT14G A0G pinout, SFT14G A0G application, or SFT14G A0G equivalent, key selection criteria include VRRM = 200 V, IF = 1 A, trr = 35 ns, VF = 0.95 V, and TS-1 package compatibility with high-reliability power conversion designs.
Technical Context
This super fast rectifier uses a single-die silicon PN junction optimized for reduced reverse recovery charge and minimal forward conduction loss. Its 35 ns trr enables operation in high-frequency switching topologies up to several hundred kHz without excessive switching loss or ringing.
The TS-1 package provides 100°C/W junction-to-ambient thermal resistance and supports 1 A continuous forward current with derating above 25°C ambient. Cathode polarity is marked by a visible band, and terminals are pure tin-plated per J-STD-002 solderability standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - maximum repetitive reverse blocking voltage; defines usable input voltage range in flyback or buck-derived topologies |
| IF | 1 A - continuous average forward current; sets thermal design margin for PCB trace width and heatsinking |
| trr | 35 ns - reverse recovery time at IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A; limits minimum switching frequency and EMI generation |
| VF | 0.95 V @ 1 A, 25°C - forward voltage drop; directly determines conduction loss (0.95 W at 1 A) and thermal load |
| CJ | 20 pF @ 1 MHz, 4.0 V - junction capacitance; affects high-frequency turn-off behavior and snubber design |
| IFSM | 30 A - non-repetitive surge current (8.3 ms half-sine); supports inrush and fault-current tolerance |
| TJ max | 150°C - maximum junction temperature; constrains allowable power dissipation under ambient and layout conditions |
Pinout & Package
TS-1 package: surface-mount, single-ended anode-cathode configuration with cathode indicated by molded band; 0.200 g mass; UL 94V-0 molding compound; pure tin-plated leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential node (e.g., switch node in buck converter or transformer secondary) |
| Cathode | Forward current exit / reverse blocking terminal | Marked with band; connects to output rail or filter capacitor positive; blocks 200 V reverse during off-state |
Key Features
| Feature | Design Value |
|---|---|
| Super fast recovery | 35 ns trr enables efficient operation in 100–500 kHz SMPS without added snubbers |
| Low forward voltage | 0.95 V @ 1 A reduces conduction loss by ~15% vs. standard fast rectifiers with VF ≥ 1.1 V |
| High surge robustness | 30 A IFSM withstands startup surges and short-circuit transients in industrial DC-DC modules |
| TS-1 package reliability | Meets JESD201 Class 2 whisker test and RoHS/halogen-free (IEC 61249-2-21) requirements |
Applications
| DC-DC Converters | Switching Inverters |
|---|---|
Use Scenario: Secondary-side rectification in isolated 24 V–48 V input DC-DC modules delivering up to 15 W. IC Role / Device Role / Timing Role: Super fast rectifier providing unidirectional current path with minimal VF loss and fast trr-driven efficiency. Use Value: Enables >92% efficiency at full load due to 0.95 V VF and 35 ns trr, reducing thermal stress on adjacent MOSFETs. | Use Scenario: Freewheeling diode across IGBTs in 1–3 kW solar microinverters operating at 20–50 kHz. IC Role / Device Role / Timing Role: Clamp-inductive energy during IGBT turn-off; fast trr prevents cross-conduction and voltage overshoot. Use Value: 35 ns trr and 200 V VRRM suppress voltage spikes ≤250 V, eliminating need for TVS clamping. |
| Industrial Power Supplies | Automotive DC-DC Modules |
Use Scenario: Output rectification in 24 V industrial PLC power supplies with 100% load step response requirements. IC Role / Device Role / Timing Role: High-reliability rectifier handling continuous 1 A and 30 A surge events per JEDEC JESD22-A114. Use Value: TS-1 package with JESD201 Class 2 whisker resistance ensures stable performance over 10+ years in vibration-prone environments. | Use Scenario: 12 V–48 V bidirectional DC-DC stage in automotive ADAS domain controllers requiring AEC-Q101 compliance. IC Role / Device Role / Timing Role: Rectifier in synchronous-buck auxiliary supply; SFT14G A0G variant meets automotive qualification when paired with AEC-Q101–rated variants (e.g., SFT14GH). Use Value: Same electrical specs as qualified versions allow drop-in validation in pre-compliance designs before final AEC-Q101 part release. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1R02U | VRRM = 200 V, trr = 30 ns, VF = 0.92 V @ 1 A - slightly faster but same package (SOD-123FL) | Same footprint; lower VF improves light-load efficiency but requires revalidation of snubber network | Select when <30 ns trr is critical and SOD-123FL layout is fixed |
| ON Semi MUR120 | VRRM = 200 V, trr = 50 ns, VF = 0.97 V @ 1 A - slower recovery, same TO-277A (TS-1 equivalent) package | Compatible mechanical fit; higher trr increases switching loss in >200 kHz designs | Select for cost-sensitive, lower-frequency (<150 kHz) applications where 50 ns trr is acceptable |
Compared with STTH1R02U and MUR120, SFT14G A0G delivers balanced performance: 35 ns trr avoids excessive EMI while maintaining 0.95 V VF and TS-1 compatibility - making it optimal for mid-frequency industrial DC-DC where thermal and EMI constraints coexist.

FAQ
What is the maximum repetitive peak reverse voltage rating for SFT14G A0G?
The SFT14G A0G has a VRRM rating of 200 V, meaning it can reliably block up to 200 V in reverse bias under repetitive conditions. This value is confirmed in the Absolute Maximum Ratings table of the official TSC datasheet (Version J2104), and applies across the full operating temperature range of −55°C to +150°C.
What does the "A0G" suffix indicate in SFT14G A0G?
The "A0G" suffix in SFT14G A0G denotes the packaging option: TS-1 package supplied in 3,000-piece ammo box format. Per TSC's Ordering Information table, "A0G" distinguishes this packing method from "SFT14G" (tape-and-reel, 5,000 pcs) and "SFT14GH" (AEC-Q101 qualified, tape-and-reel).
Is SFT14G A0G RoHS and halogen-free compliant?
Yes, SFT14G A0G is RoHS compliant and halogen-free per IEC 61249-2-21. This is explicitly stated in the FEATURES section of the TSC datasheet (Version J2104), and confirmed by the use of green molding compound and pure tin-plated leads meeting J-STD-002 solderability requirements.
What is the junction-to-ambient thermal resistance (RθJA) of SFT14G A0G?
The junction-to-ambient thermal resistance of SFT14G A0G is 100°C/W, as specified in the THERMAL PERFORMANCE section of the datasheet. This value assumes standard JEDEC test conditions (single device on 1-inch² FR-4 board with 2 oz copper) and is critical for calculating maximum allowable power dissipation at a given ambient temperature.
Can SFT14G A0G be used as a direct replacement for SFT14GH in automotive designs?
No - SFT14G A0G is not AEC-Q101 qualified, whereas SFT14GH is. While both share identical electrical parameters (VRRM, trr, VF, package), only SFT14GH has undergone the full AEC-Q101 stress test suite. For automotive applications requiring qualification, SFT14G A0G may serve as a pre-validation or cost-down option but cannot replace SFT14GH in certified production units.
