Product details
Overview
SFF1002GA from Taiwan Semiconductor is a 10A, 100V super fast recovery rectifier diode in ITO-220AB package with dual-die configuration, VF = 0.975 V at IF = 5 A and TJ = 25°C, trr = 35 ns, and RθJC = 8 °C/W - used in high-efficiency DC-DC converters and switching inverters.
For engineers reviewing the SFF1002GA datasheet, SFF1002GA pinout, SFF1002GA application, or SFF1002GA equivalent, key selection criteria include peak reverse voltage (100 V), forward surge capability (125 A), thermal resistance, AEC-Q101 qualification eligibility, and junction capacitance (70 pF) for high-frequency switching integrity.
Technical Context
The SFF1002GA integrates two independent silicon die in a single ITO-220AB thermally enhanced package, enabling dual-diode operation without external paralleling. Its super fast recovery (trr ≤ 35 ns) and low forward voltage support high-frequency (>100 kHz) hard-switched topologies.
Designed for automotive-grade reliability when ordered with 'H' suffix, it meets JESD201 Class 2 whisker resistance and UL 94V-0 flammability. The device operates across –55°C to +150°C junction temperature range with 125 A non-repetitive surge rating per half-sine pulse.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - maximum repetitive reverse blocking voltage; defines safe operating limit in flyback or freewheeling paths |
| IF | 10 A - continuous average forward current at TC = 100°C; determines heatsink sizing in conduction-limited designs |
| IFSM | 125 A - peak non-repetitive surge current (8.3 ms); supports inrush and fault-current handling in SMPS |
| VF @ 5A/25°C | 0.975 V - forward voltage drop per diode; directly impacts conduction loss and thermal design |
| trr | 35 ns - reverse recovery time; enables efficient operation up to ~500 kHz switching frequencies |
| RθJC | 8 °C/W - junction-to-case thermal resistance; enables direct mounting to heatsink with predictable ΔT |
| CJ @ 1 MHz | 70 pF - junction capacitance per diode; affects EMI generation and snubber requirements |
Pinout & Package
Package: ITO-220AB - thermally optimized 3-terminal through-hole package with isolated tab (cathode-connected tab), matte tin-plated leads, UL 94V-0 molding compound, and 1.80 g mass. Mounting torque ≤ 0.56 N·m.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Tab (Anode) | Anode connection (isolated) | Electrically isolated metal tab serves as anode terminal; requires insulating washer if mounted to grounded heatsink |
| Lead 1 (Cathode) | Cathode connection | Primary cathode output; carries full forward current; solderable per J-STD-002 |
| Lead 2 (Cathode) | Cathode connection | Second cathode terminal for dual-die configuration; enables Kelvin sensing or parallel routing |
Key Features
| Feature | Design Value |
|---|---|
| Super fast recovery (trr ≤ 35 ns) | Reduces switching losses and EMI in high-frequency DC-DC converters and PFC stages |
| Dual-die configuration | Enables redundant or interleaved operation without external paralleling; improves current sharing reliability |
| Low VF (0.975 V @ 5 A) | Lowers conduction loss by ~15% vs. standard fast rectifiers, improving efficiency in 12–48 V output rails |
| AEC-Q101 qualification option | Supports automotive under-hood applications when ordered as SFF1002GAH; includes whisker testing and stress validation |
| UL Recognized (E326243) | Validates safety compliance for end-equipment certification in industrial and medical power supplies |
Applications
| DC-DC Converter | Switching Inverter |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH10R06DJF | 600 V VRRM, 10 A IF, VF = 1.15 V @ 5 A, trr = 30 ns, TO-220AC package (single cathode) | Higher voltage rating suits 400 V bus applications; lower trr but higher VF increases conduction loss | Select when >300 V reverse blocking required; verify heatsink compatibility due to different pinout and thermal path |
| ON Semi MUR1020CT | 200 V VRRM, 10 A IF, VF = 0.92 V @ 5 A, trr = 35 ns, TO-220AB package (dual cathode) | Lower VRRM limits use to ≤200 V systems; slightly lower VF improves efficiency at light loads | Prefer for cost-sensitive 24–48 V industrial supplies where 200 V margin suffices and dual-cathode routing is needed |
Compared with STTH10R06DJF and MUR1020CT, the SFF1002GA offers optimal balance of 100 V rating, dual-cathode flexibility, and 0.975 V VF for mid-voltage DC-DC and inverter freewheeling - with verified thermal performance (8 °C/W) and AEC-Q101 readiness.

FAQ
What is the maximum junction temperature rating for the SFF1002GA?
The SFF1002GA has a maximum junction temperature (TJ MAX) of +150°C, validated across its full operating range from –55°C to +150°C. This rating enables reliable operation in high-ambient environments such as enclosed power supplies and under-hood automotive modules when paired with appropriate thermal management per its 8 °C/W RθJC specification.
Is the SFF1002GA pin-compatible with other devices in the SFF100xGA series?
Yes, all SFF1001GA through SFF1008GA share identical ITO-220AB packaging, pinout, and mechanical footprint - only VRRM and VF vary across the series. The SFF1002GA uses the same tab-anode / dual-cathode lead configuration, allowing direct substitution within the same voltage class when thermal and electrical margins permit.
Does the SFF1002GA have AEC-Q101 qualification?
The base SFF1002GA is not AEC-Q101 qualified; however, the variant SFF1002GAH is fully AEC-Q101 qualified and undergoes additional stress testing including temperature cycling, HTSL, and JESD201 Class 2 whisker evaluation. Customers requiring automotive compliance must specify the 'H' suffix at order time.
What is the reverse leakage current specification for the SFF1002GA at elevated temperature?
At TJ = 125°C and rated VR = 100 V, the SFF1002GA exhibits a maximum reverse leakage current (IR) of 400 µA per diode. At TJ = 25°C, IR is limited to 10 µA - critical for low-power standby modes and high-impedance sensing circuits where leakage could affect system accuracy.
How does the dual-die structure of the SFF1002GA impact PCB layout?
The dual-die structure of the SFF1002GA provides two separate cathode terminals (Leads 1 and 2), enabling independent routing to minimize shared trace inductance in high-di/dt applications. This layout flexibility reduces ringing and improves EMI performance compared to single-cathode alternatives - especially beneficial in interleaved or multi-phase converter outputs.
