Product details
Overview
SFF1602G from Taiwan Semiconductor is a 16A, 100V super fast recovery rectifier diode in ITO-220AB package, featuring 35ns reverse recovery time, 0.975V forward voltage at 8A/25°C, and 125A surge capability - used in DC-DC converters and switching inverters requiring high-efficiency freewheeling.
For engineers reviewing the SFF1602G datasheet, SFF1602G pinout, SFF1602G application, or SFF1602G equivalent, key selection criteria include VRRM=100V, IF=16A, trr=35ns, RθJC=1.5°C/W, and AEC-Q101 qualification option (SFF1602GH), critical for automotive power supply and industrial SMPS design.
Technical Context
The SFF1602G integrates dual die configuration in a single ITO-220AB package with isolated cathodes, enabling independent use as two discrete super fast rectifiers or parallel operation. Its 35ns trr and low Qrr minimize switching losses in high-frequency (>100kHz) topologies.
Thermal performance is defined by RθJC=1.5°C/W and TJ(max)=150°C, supporting continuous conduction mode operation under forced-air or heatsink-cooled conditions. The device meets UL 94V-0 and JESD201 Class 2 whisker requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - maximum repetitive reverse blocking voltage; sets upper limit for input/output voltage rails in buck, boost, and flyback designs |
| IF | 16 A - average forward current rating at case temperature ≤75°C; determines continuous power handling without derating |
| trr | 35 ns - reverse recovery time at IF=0.5A, IR=1.0A, Irr=0.25A; enables efficient operation up to ~500kHz switching frequency |
| VF | 0.975 V @ 8A, 25°C - forward voltage drop per diode; directly impacts conduction loss and thermal design in high-current paths |
| RθJC | 1.5 °C/W - junction-to-case thermal resistance; defines minimum heatsink requirement for 16A continuous operation |
| IFSM | 125 A - non-repetitive surge current (8.3ms half-sine); supports inrush and fault-current tolerance in power supplies |
Pinout & Package
Package: ITO-220AB - insulated thermoplastic outline with copper leadframe, matte tin-plated leads (J-STD-002 compliant), UL 94V-0 molding compound, and 0.56 N·m max mounting torque. Polarity marked on case.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 (Lead 1) | Input terminal for first diode | Connects to high-side switch node or transformer secondary in freewheeling path |
| Cathode 1 (Lead 2) | Output terminal for first diode | Routes rectified current to output capacitor or load; electrically isolated from Cathode 2 |
| Anode 2 (Lead 3) | Input terminal for second diode | Enables dual-channel rectification or synchronous bootstrap supply generation |
| Cathode 2 (Lead 4) | Output terminal for second diode | Provides independent return path; allows split-rail or dual-output converter implementation |
Key Features
| Feature | Design Value |
|---|---|
| Super fast recovery (trr = 35 ns) | Reduces switching losses and EMI in high-frequency SMPS, enabling smaller filter components and higher power density |
| Dual-die ITO-220AB configuration | Provides two independent 16A/100V rectifiers in one footprint, saving PCB area vs. two discrete TO-220 devices |
| Low VF (0.975 V @ 8A) | Lowers conduction loss by ~15% vs. standard fast rectifiers, improving efficiency in 12–48V output converters |
| AEC-Q101 qualified variant available | Validated for automotive under-hood applications including engine control modules and ADAS power supplies |

Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1602CT | VRRM=200V, trr=35ns, VF=0.95V @ 8A, TO-220AC package (single cathode) | Higher voltage rating but single-cathode configuration limits dual-rail flexibility | Select when 200V blocking is required and dual isolated outputs are unnecessary |
| IXYS MUR1620CT | VRRM=200V, trr=35ns, VF=1.1V @ 8A, TO-220AB package (dual cathode) | Same dual-cathode topology but higher VF increases conduction loss by ~13% | Prefer when existing layout uses TO-220AB footprint and 200V rating is mandatory |
Compared with STTH1602CT and IXYS MUR1620CT, the SFF1602G offers optimal balance of 100V rating, dual isolated cathodes, and lowest VF in its class - making it ideal for space-constrained 12–48V industrial converters where thermal headroom and layout flexibility are critical.

FAQ
What is the maximum junction temperature rating for the SFF1602G?
The SFF1602G has a maximum junction temperature (TJ(max)) of +150°C, verified per absolute maximum ratings table. This allows operation in high-ambient environments such as enclosed industrial enclosures or under-hood automotive locations when mounted on an appropriate heatsink. Thermal design must maintain TJ ≤ 150°C using the specified RθJC = 1.5°C/W and system-level RθCA.
Does the SFF1602G have AEC-Q101 qualification?
The base SFF1602G is not AEC-Q101 qualified; however, the variant SFF1602GH is explicitly qualified per AEC-Q101 Rev D. Both share identical electrical and thermal specifications, differing only in additional stress testing and traceability documentation. For automotive applications, specify SFF1602GH to ensure compliance with vehicle-grade reliability requirements.
What is the reverse recovery time (trr) test condition for the SFF1602G?
The SFF1602G reverse recovery time is measured at IF = 0.5A, IR = 1.0A, and Irr = 0.25A, per the Electrical Specifications table. This standardized condition ensures consistent comparison with other super fast rectifiers. The typical trr value is 35ns, confirmed across production lots and validated in the device's characterization curves.
How does the dual-die structure of the SFF1602G affect PCB layout?
Unlike single-diode TO-220 devices, the SFF1602G's dual-die ITO-220AB package provides two electrically isolated cathodes (Leads 2 and 4), enabling independent routing for dual-output or split-rail converters without extra isolation components. This reduces board area by ~30% versus two discrete TO-220 rectifiers while maintaining thermal coupling for shared heatsinking.
What is the marking code for the SFF1602G on the device body?
The SFF1602G is marked "SFF1602G" on the device body, followed by date code (YWW), factory code (F), and green compound indicator (G), per the Marking Diagram in the datasheet. This full marking confirms authenticity, voltage grade (100V), and RoHS/halogen-free compliance - critical for traceability in regulated production environments.
