Product details

Overview

SFA1006G from Taiwan Semiconductor is a 400 V, 10 A super fast recovery rectifier diode in TO-220AC package, featuring 35 ns reverse recovery time, 1.30 V forward voltage at 10 A/25°C, and 125 A surge capability - deployed in DC-DC converters and switching inverters for high-efficiency power conversion.

For engineers reviewing the SFA1006G datasheet, SFA1006G pinout, SFA1006G application, or SFA1006G equivalent, key selection criteria include V_RRM = 400 V, I_F = 10 A, t_rr = 35 ns, V_F = 1.30 V (10 A, 25°C), and R_θJC = 3.5 °C/W - critical for thermal management and switching loss optimization in high-frequency SMPS designs.

Technical Context

The SFA1006G employs a single-die planar epitaxial structure optimized for super-fast recovery, with minority carrier lifetime control enabling t_rr = 35 ns under I_F = 0.5 A, I_R = 1.0 A, I_rr = 0.25 A test conditions. Its 400 V V_RRM and 280 V V_R(RMS) support medium-voltage DC bus applications.

Thermally, the TO-220AC package delivers R_θJC = 3.5 °C/W, enabling reliable operation up to T_J = 150°C. Reverse leakage remains ≤10 µA at 25°C and ≤400 µA at 100°C, supporting stable blocking in freewheeling paths.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	400 V - maximum repetitive reverse voltage; defines safe operating range in 350–400 V DC bus systems
I_F	10 A - average forward current; supports continuous conduction mode in 100–300 W SMPS
t_rr	35 ns - reverse recovery time; enables efficient operation up to ~200 kHz switching frequency
V_F	1.30 V @ 10 A, 25°C - forward voltage drop; determines conduction loss of ~13 W at full load
R_θJC	3.5 °C/W - junction-to-case thermal resistance; allows ~31 W power dissipation with 110°C case rise
I_FSM	125 A - non-repetitive surge current (8.3 ms half-sine); withstands startup/load dump transients
C_J	50 pF @ 1 MHz, 4 V - junction capacitance; minimizes capacitive switching loss and EMI generation

Pinout & Package

TO-220AC package: single-ended, 3-lead outline with isolated tab (cathode-connected tab), matte tin-plated leads compliant with J-STD-002, UL 94V-0 molding compound, 1.80 g weight, max mounting torque 0.56 N·m.

Cathode (Lead 2)	Forward current exit / high-side return	Electrically tied to metal tab; must be thermally anchored to heatsink with electrical isolation if needed
Tab (Cathode)	Primary heat path & cathode terminal	Provides dominant thermal conduction path; electrically active - isolation required for floating topologies

Key Features

Feature	Design Value
Super fast recovery (t_rr = 35 ns)	Reduces switching losses and EMI vs. standard fast recovery diodes in 100–200 kHz converters
Low V_F = 1.30 V @ 10 A	Minimizes conduction loss in high-current output stages, improving efficiency by ~0.5–1.2% over 1.5 V alternatives
R_θJC = 3.5 °C/W	Enables compact heatsinking - 110°C temperature rise at 31 W dissipation without forced air
AEC-Q101 qualified option (SFA1006GH)	Validated for automotive under-hood environments including temperature cycling, humidity, and mechanical shock
RoHS + halogen-free	Complies with IEC 61249-2-21; suitable for consumer, industrial, and automotive PCB assembly processes

Equivalent & Alternatives

The following parts are listed as comparable options for similar super fast rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH10R04DJF	V_RRM = 400 V, t_rr = 30 ns, V_F = 1.25 V @ 10 A - slightly faster, lower V_F, but R_θJC = 4.0 °C/W	Better for ultra-high-frequency (>300 kHz) designs; less thermally efficient at high ambient	Prefer when t_rr < 30 ns is mandatory and heatsink area is ample
ON Semi MUR1040	V_RRM = 400 V, t_rr = 50 ns, V_F = 1.35 V @ 10 A - slower recovery, higher V_F, R_θJC = 3.7 °C/W	Lower cost; acceptable for ≤100 kHz converters where EMI is less critical	Prefer for cost-sensitive industrial supplies with relaxed switching speed requirements

Compared with STTH10R04DJF and MUR1040, the SFA1006G offers the best balance of thermal performance (3.5 °C/W), mid-range recovery speed (35 ns), and proven AEC-Q101 qualification path - making it optimal for automotive-grade 400 V DC-DC and industrial SMPS requiring reliability and thermal headroom.

FAQ

What is the maximum junction temperature rating for the SFA1006G?

The SFA1006G has a maximum junction temperature (T_J) rating of +150°C, verified per absolute maximum ratings table. This allows operation in high-ambient environments such as under-hood automotive locations or enclosed industrial enclosures. Derating curves confirm 10 A average current is maintainable up to 125°C case temperature when mounted on an adequate heatsink. The SFA1006G must not exceed 150°C at the die to ensure long-term reliability.

Is the SFA1006G pin-compatible with other TO-220AC rectifiers like the MUR1040?

Yes - the SFA1006G uses the standard TO-220AC outline with identical lead spacing, tab dimensions, and mounting hole location as MUR1040 and STTH10R04DJF. All three share anode–cathode–tab pinout (Lead 1 = anode, Lead 2 = cathode, tab = cathode). Mechanical compatibility enables direct PCB footprint reuse, though thermal and electrical validation is required due to differences in R_θJC, t_rr, and V_F.

Does the SFA1006G meet automotive qualification standards?

The base SFA1006G is not AEC-Q101 qualified, but its variant SFA1006GH is fully AEC-Q101 qualified per version K2103 documentation. The GH suffix denotes qualification for automotive applications including temperature cycling, mechanical shock, and humidity testing. For automotive designs, specify SFA1006GH; the SFA1006G remains suitable for industrial and telecom use where AEC-Q101 is not mandated.

What is the reverse recovery charge (Q_rr) of the SFA1006G?

The datasheet does not publish Q_rr directly, but based on t_rr = 35 ns, I_R = 1.0 A, and I_rr = 0.25 A test conditions, typical Q_rr is estimated at ≤15 nC. This value is derived from industry-standard trapezoidal approximation (Q_rr ≈ 0.5 × I_rr × t_rr) and aligns with measured CJ = 50 pF and low stored charge design. For precise Q_rr-dependent snubber sizing, refer to TSC's application note AN-SFA-01.

How does the SFA1006G's forward voltage compare across temperature?

The SFA1006G exhibits a negative temperature coefficient for V_F: at 10 A, V_F decreases from 1.30 V at 25°C to ~1.15 V at 125°C. This behavior reduces conduction loss at elevated temperatures, improving thermal stability in sustained high-load operation. The datasheet confirms this trend via Fig.4 (Typical Forward Characteristics), showing consistent slope across TJ = 25°C to 150°C.
