Product details
Overview
SFF1003GA from Taiwan Semiconductor is a 150 V, 10 A super fast recovery rectifier diode in ITO-220AB package with dual-die configuration, 35 ns reverse recovery time, and 0.975 V forward voltage at 5 A and 25°C - used in DC-DC converters and freewheeling paths in automotive-grade switching power supplies.
For engineers reviewing the SFF1003GA datasheet, SFF1003GA pinout, SFF1003GA application, or SFF1003GA equivalent, key selection criteria include its 150 V repetitive peak reverse voltage, 125 A surge rating, 8 °C/W junction-to-case thermal resistance, AEC-Q101 qualification option (SFF1003GAH), and compatibility with high-frequency SMPS topologies requiring low VF and fast trr.
Technical Context
The SFF1003GA integrates two independent silicon die in a single ITO-220AB thermally enhanced package, enabling dual-diode functionality without external paralleling. Its super fast recovery (trr ≤ 35 ns) and low VF (0.975 V @ 5 A, 25°C) reduce switching losses and conduction losses simultaneously in hard-switched topologies.
Designed for operation up to 150°C junction temperature, it delivers stable performance under transient thermal stress, supported by UL 94V-0 molding compound, JESD201 Class 2 whisker resistance, and matte tin-plated leads compliant with J-STD-002 solderability standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 150 V - maximum repetitive reverse blocking voltage; defines safe operating range in flyback/freewheeling clamp circuits |
| IF | 10 A - continuous forward current rating at case temperature ≤ 100°C; determines heatsink sizing in 12–48 V DC-DC stages |
| IFSM | 125 A - non-repetitive surge current (8.3 ms half-sine); supports inrush and fault-current handling in industrial SMPS |
| trr | 35 ns - reverse recovery time at IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A; enables >100 kHz switching without excessive switching loss |
| VF | 0.975 V @ 5 A, 25°C - forward voltage drop per diode; directly impacts conduction loss and thermal design in high-current paths |
| RθJC | 8 °C/W - junction-to-case thermal resistance; allows direct thermal interface to heatsink without derating penalties at rated IF |
| CJ | 70 pF @ 1 MHz, VR = 4 V - junction capacitance per diode; influences EMI generation and snubber design in high-dV/dt environments |

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, 30 ns trr, TO-220AC package (single diode) | Higher voltage rating but no dual-die integration; requires two devices for same function | Select when >300 V blocking is needed or dual-die redundancy is not required |
| VS-10ETH06-M3 | 600 V VRRM, 10 A IF, 35 ns trr, TO-220AB package, halogen-free | Single-diode TO-220AB; lacks dual-die configuration and AEC-Q101 option | Prefer for cost-sensitive industrial designs where dual-die benefit is secondary |
Compared with STTH10R06DJF and VS-10ETH06-M3, the SFF1003GA uniquely combines 150 V rating, dual-die integration, and AEC-Q101 qualification in one ITO-220AB package - delivering space, thermal, and reliability advantages in automotive auxiliary supplies and compact DC-DC converters.

FAQ
What is the maximum junction temperature rating for the SFF1003GA?
The SFF1003GA has a maximum junction temperature (TJ MAX) of +150°C, verified across its full operating range from –55°C to +150°C. This rating enables reliable operation in high-ambient environments such as engine bay-mounted power supplies or enclosed industrial enclosures, provided thermal design maintains case temperature within limits defined by its 8 °C/W RθJC and 10 A IF derating curve.
Is the SFF1003GA pin-compatible with other parts in the SFF100xGA family?
Yes, all SFF100xGA variants - including SFF1001GA through SFF1008GA - share identical ITO-220AB package dimensions, pinout, and terminal configuration. The only differences are VRRM rating (50–600 V) and forward voltage grading; therefore, SFF1003GA can be substituted within the same footprint when 150 V blocking suffices and thermal/mechanical constraints permit.
Does the SFF1003GA have AEC-Q101 qualification?
The base SFF1003GA is not AEC-Q101 qualified, but the variant SFF1003GAH is fully AEC-Q101 qualified per Rev. E2105 documentation. The "H" suffix denotes qualification, and both versions share identical electrical and thermal specifications except for the added automotive reliability validation - making SFF1003GAH the appropriate choice for automotive body control modules or on-board chargers.
What is the reverse recovery time (trr) test condition for the SFF1003GA?
The SFF1003GA reverse recovery time is specified as ≤35 ns under the exact test conditions: IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A, with measurement performed at TA = 25°C. This value reflects real-world hard-switching behavior in flyback and forward converters, and is confirmed across production lots per TSC's characterization methodology in Version E2105.
How does the dual-die configuration of the SFF1003GA improve system-level reliability?
The dual-die configuration in the SFF1003GA provides inherent redundancy and matched dynamic characteristics between the two anodes sharing a common cathode. This eliminates thermal and timing skew seen when paralleling discrete diodes, reduces hot-spot formation under unbalanced load, and increases mean time between failures in mission-critical freewheeling applications - a benefit confirmed in TSC's accelerated life testing for the SFF100xGA family.
