Product details
Overview
SF1604G from Taiwan Semiconductor is a 200V repetitive peak reverse voltage, super fast recovery rectifier diode in TO-220AB package, rated for 16A average forward current and 125A surge current, with 35ns reverse recovery time and 0.975V forward voltage at 8A/25°C - used in high-frequency switching mode power supplies and freewheeling paths.
For engineers reviewing the SF1604G datasheet, SF1604G pinout, SF1604G application, or SF1604G equivalent, key selection criteria include VRRM = 200V, IF = 16A, trr = 35ns, VF = 0.975V @ 8A/25°C, and TO-220AB thermal resistance RθJC = 1.5°C/W for thermal design validation.
Technical Context
The SF1604G is a single-die, unidirectional super fast rectifier optimized for high-efficiency DC-DC conversion and snubberless flyback topologies. Its 35ns reverse recovery time enables operation up to several hundred kHz while minimizing switching losses and EMI generation.
Designed with low Qrr and 80pF junction capacitance at 4V reverse bias, the SF1604G supports clean turn-off in hard-switched converters. Its 1.5°C/W junction-to-case thermal resistance allows direct heatsink mounting for sustained 16A conduction without derating below 100°C case temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - maximum non-repetitive reverse blocking voltage; defines usable input voltage range in buck-derived topologies |
| IF | 16 A - continuous average forward current at TC = 100°C; sets minimum heatsink requirement for 12–24V output converters |
| trr | 35 ns - measured at IF = 0.5A, IR = 1.0A, Irr = 0.25A; enables <500 kHz switching without excessive diode loss |
| VF | 0.975 V @ 8A, 25°C - forward drop directly impacts conduction loss and thermal rise in high-current secondary-side rectification |
| CJ | 80 pF @ 1 MHz, 4.0 V - low junction capacitance reduces capacitive turn-on loss and improves EMI profile in high-dV/dt circuits |
| RθJC | 1.5 °C/W - thermal resistance from junction to case; enables 16A operation with ≤22.5°C temperature rise across heatsink interface |
Pinout & Package
TO-220AB package with isolated tab (case), 3-terminal configuration: Anode (pin 1), Cathode (pin 2), and electrically isolated metal tab (pin 3, mechanical only). Matte tin-plated leads compliant with J-STD-002 solderability standard.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Lead) | Anode | Main current entry point; connects to transformer secondary or switch node in freewheeling path |
| Pin 2 (Lead) | Cathode | Main current exit point; ties to output capacitor or ground return in step-down configurations |
| Metal Tab | Isolated Case / Thermal Path | Electrically isolated but thermally conductive surface; mounts directly to heatsink without insulator required |
Key Features
| Feature | Design Value |
|---|---|
| Super fast recovery | trr = 35 ns enables high-frequency SMPS operation with minimal switching loss and reduced EMI |
| Low forward voltage | VF = 0.975 V @ 8A/25°C lowers conduction loss by ~15% vs. standard FRD equivalents at same current |
| High surge capability | IFSM = 125 A (8.3 ms half-sine) supports robust startup and transient overload handling |
| Thermally optimized package | RθJC = 1.5°C/W allows direct heatsink mounting without thermal pad, simplifying thermal layout |
Applications
| DC-DC Converters | Switching Inverters |
|---|---|
Use Scenario: Secondary-side rectification in isolated 48V–12V buck-derived telecom power modules operating at 250–400 kHz. IC Role / Device Role / Timing Role: Super fast rectifier providing low-loss, low-noise current path during synchronous or asynchronous flyback/flyforward conduction phase. Use Value: 35ns trr and 0.975V VF reduce total power loss by ≥0.8W per diode versus standard FRDs at 12A load, improving efficiency by 0.6–0.9%. | Use Scenario: Freewheeling path in three-phase motor drive inverters with IGBT-based half-bridge legs. IC Role / Device Role / Timing Role: Unidirectional clamp diode absorbing inductive kickback during IGBT turn-off, requiring fast recovery to prevent cross-conduction. Use Value: 80pF CJ and 35ns trr limit voltage overshoot and oscillation during rapid current reversal, reducing gate driver stress and EMI filter burden. |
| AC-DC Adapters | Industrial Power Supplies |
Use Scenario: Output rectification in compact 65W–100W USB-C PD adapters using active-clamp flyback topology. IC Role / Device Role / Timing Role: High-current output rectifier conducting 10–16A average current with minimal thermal rise under continuous load. Use Value: RθJC = 1.5°C/W and TO-220AB isolation allow direct heatsink attachment, eliminating thermal interface material and saving PCB area. | Use Scenario: Input PFC boost diode and output rectifier in 300W industrial AC-DC front-end supplies with wide ambient range (-40°C to +85°C). IC Role / Device Role / Timing Role: Dual-role rectifier supporting both high-voltage boost stage and low-VF output stage in multi-rail systems. Use Value: 150°C max junction temperature and -55°C to +150°C storage rating ensure reliability across extended industrial temperature profiles without derating. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1602CW | VRRM = 200V, trr = 30ns, VF = 0.95V @ 8A/25°C, TO-247 package, RθJC = 1.0°C/W | Lower VF and faster trr, but larger TO-247 footprint and higher cost; requires PCB rework for replacement | Select when thermal budget is tighter and board space permits TO-247 mounting |
| ON Semi MUR1620CT | VRRM = 200V, trr = 35ns, VF = 1.05V @ 8A/25°C, TO-220AB dual common-cathode configuration | Same package and trr, but higher VF and dual-diode layout; not pin-compatible for single-diode use cases | Select only if dual-diode topology is required; otherwise SF1604G offers lower conduction loss |
Compared with STTH1602CW and MUR1620CT, the SF1604G delivers optimal balance of low VF, industry-standard TO-220AB fit, and proven thermal performance - making it preferred for cost-sensitive, space-constrained 16A rectification where 0.975V drop and 1.5°C/W RθJC meet system-level thermal targets.

FAQ
What is the maximum junction temperature rating for SF1604G?
The SF1604G has a maximum junction temperature (TJ) rating of +150°C, verified per absolute maximum ratings table in the official Taiwan Semiconductor datasheet Version I2104. This rating applies across the full operating range and supports reliable operation in industrial environments with elevated ambient temperatures. The SF1604G maintains specified electrical parameters up to this limit when thermal design ensures junction temperature does not exceed +150°C during steady-state or transient conditions.
Is SF1604G AEC-Q101 qualified?
The base SF1604G part is not AEC-Q101 qualified; qualification applies only to the SF1604GH variant, which includes the "H" suffix in the ordering code. Per Taiwan Semiconductor's ordering information table, "H" explicitly denotes AEC-Q101 compliance. The SF1604G shares identical electrical and thermal specifications with SF1604GH but lacks automotive-grade screening and test documentation. For automotive applications, SF1604GH must be specified.
What is the reverse recovery time (trr) test condition for SF1604G?
The SF1604G reverse recovery time is specified as trr = 35 ns, measured under the exact conditions stated in the Electrical Specifications table: IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. These conditions reflect standardized diode recovery testing per JEDEC guidelines and are repeatable across production lots. The value is guaranteed maximum, not typical, ensuring design margin for high-frequency switching stability.
Does SF1604G have a dual-diode configuration?
No, the SF1604G is a single-die, single-diode device in TO-220AB package. Although the SF1601G–SF1608G family includes dual-diode variants (e.g., SF1604CT), the SF1604G marking and ordering code correspond exclusively to a single-anode/single-cathode rectifier. Pinout confirmation shows only two active terminals (anode and cathode) plus an isolated thermal tab - no internal common-cathode or common-anode structure.
What is the junction-to-case thermal resistance (RθJC) of SF1604G?
The SF1604G has a junction-to-case thermal resistance (RθJC) of 1.5°C/W, as published in the Thermal Performance section of the Taiwan Semiconductor datasheet Version I2104. This value is measured under standard JEDEC test conditions and applies to the TO-220AB package with proper mounting torque (≤0.56 N·m). It enables accurate thermal modeling for heatsink sizing when the metal tab is directly attached to a heatsink.
