Product details

Overview

SF62G from Taiwan Semiconductor is a 100V, 6A super fast recovery rectifier diode in DO-201AD package, featuring 35ns reverse recovery time, 0.975V forward voltage at 6A/25°C, and 150A surge capability - deployed in switching-mode DC-DC converters and freewheeling paths for high-efficiency power supplies.

For engineers reviewing the SF62G datasheet, SF62G pinout, SF62G application, or SF62G equivalent, key selection criteria include V_RRM = 100V, I_F = 6A, t_rr = 35ns, R_θJA = 40°C/W, and DO-201AD mechanical compatibility with automated through-hole or surface-mount reflow assembly.

Technical Context

The SF62G uses a single-die silicon PN junction optimized for fast switching in hard-commutated topologies. Its 35ns reverse recovery time enables operation up to several hundred kHz without excessive switching loss, while the 0.975V V_F at rated current minimizes conduction loss in continuous conduction mode.

Thermally, the device achieves R_θJL = 5°C/W to lead and R_θJA = 40°C/W in free-air, supporting sustained 6A average forward current up to +125°C ambient when mounted on ≥1in² copper area - critical for compact industrial SMPS and automotive auxiliary power modules.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	100 V - maximum repetitive reverse blocking voltage; defines safe operating range in 12–48V input DC-DC stages
I_F	6 A - average forward current rating; supports continuous output up to ~75W at 12V with adequate heatsinking
t_rr	35 ns - measured at I_F = 0.5A, I_R = 1.0A, I_rr = 0.25A; enables efficient operation in 200–500 kHz converters
V_F	0.975 V @ 6A, 25°C - low conduction loss reduces thermal stress and improves efficiency vs. standard fast rectifiers
I_FSM	150 A - non-repetitive surge rating (8.3ms half-sine); withstands inrush and fault transients in unregulated inputs
C_J	100 pF @ 1MHz, 4V - low junction capacitance limits displacement current and EMI in high-dv/dt switching nodes
R_θJA	40 °C/W - thermal resistance in free-air; requires PCB copper area ≥1.0 in² for full 6A derating to +75°C ambient

Pinout & Package

DO-201AD axial-leaded package with cathode band marking; leads are pure tin-plated, J-STD-002 solderable, and meet JESD201 Class 2 whisker resistance.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH6L06D (STMicroelectronics)	V_RRM = 600V, t_rr = 35ns, V_F = 1.15V @ 6A - higher blocking, higher V_F	Better suited for 400V+ PFC output or universal input adapters	Select when >100V reverse margin required; avoid if optimizing for lowest conduction loss at 100V-class systems
ES6D (ON Semiconductor)	V_RRM = 200V, t_rr = 35ns, V_F = 0.92V @ 6A - lower V_RRM, slightly lower V_F	Optimized for 24–48V telecom and server PSUs with tighter V_F budget	Prefer when 200V rating suffices and sub-0.95V V_F is critical for thermal design

Compared with STTH6L06D and ES6D, the SF62G offers the optimal balance of 100V rating, 0.975V V_F, and proven DO-201AD manufacturability - making it the preferred choice for cost-sensitive, thermally constrained 48V industrial and automotive auxiliary supplies.

FAQ

What is the maximum junction temperature rating for SF62G?

The SF62G has a maximum junction temperature (T_J) of +150°C and a storage temperature range of –55°C to +150°C. This rating allows reliable operation in under-hood automotive environments and enclosed industrial enclosures when mounted with appropriate thermal relief. The SF62G maintains specified electrical performance up to this limit, provided thermal design respects R_θJA = 40°C/W in free air or lower with PCB copper heatsinking.

Is SF62G AEC-Q101 qualified?

The base SF62G is not AEC-Q101 qualified; however, the variant SF62GH is fully AEC-Q101 qualified and shares identical electrical and thermal specifications. SF62GH undergoes additional stress testing per AEC-Q101 Rev D, including accelerated life testing and temperature cycling, and is marked with "H" suffix. For automotive-grade deployment, specify SF62GH - the SF62G itself is intended for industrial and commercial applications.

What is the reverse recovery time (t_rr) test condition for SF62G?

The SF62G reverse recovery time is specified as t_rr ≤ 35ns under the condition: I_F = 0.5A, I_R = 1.0A, I_rr = 0.25A, with measurement performed at 25°C. This standardized test reflects real-world commutation behavior in hard-switched topologies. The SF62G maintains consistent t_rr across its operating temperature range, supporting stable timing in high-frequency SMPS designs.

Can SF62G replace SF61G in a 50V design?

Yes, SF62G can safely replace SF61G in a 50V-rated design because its V_RRM = 100V exceeds the 50V requirement, and all other parameters - including I_F, t_rr, and V_F - are identical or improved. The SF62G offers higher reverse margin without compromising speed or forward loss. However, verify mechanical fit and thermal layout remain compatible, as both use DO-201AD packaging.

What is the junction-to-ambient thermal resistance (R_θJA) of SF62G in free-air?

The SF62G has a junction-to-ambient thermal resistance (R_θJA) of 40°C/W when tested in free-air per JEDEC standards. This value assumes no added heatsinking and minimal PCB copper. To sustain 6A continuous current at elevated ambient temperatures, increase copper area (e.g., ≥1.0 in² on 2oz copper) or add forced airflow - the SF62G's R_θJL = 5°C/W to lead enables effective heat transfer to mounting pads or chassis connections.
