Product details
Overview
SF1605G from Taiwan Semiconductor is a 16A, 300V repetitive peak reverse voltage super fast rectifier diode in TO-220AB package, featuring 35ns reverse recovery time, 1.300V forward voltage at 8A/25°C, and dual-die configuration for high-current freewheeling in switching power supplies.
For engineers reviewing the SF1605G datasheet, SF1605G pinout, SF1605G application, or SF1605G equivalent, key selection criteria include its 300V VRRM, 125A IFSM, 1.5°C/W RθJC, AEC-Q101 qualification option (SF1605GH), and junction temperature range of –55°C to +150°C.
Technical Context
The SF1605G is a single-phase, dual-die super fast recovery rectifier optimized for high-frequency switching mode power supplies. Its 35ns trr and low 60pF junction capacitance per diode enable efficient operation in DC–DC converters up to several hundred kHz.
Designed with matte tin-plated leads compliant with J-STD-002 and UL 94V-0 molding compound, it supports automated soldering and meets JESD201 Class 2 whisker resistance. Polarity is marked on the case, and mounting torque must not exceed 0.56 N·m.
Key Specifications

|---|---|
| VRRM | 300 V - Maximum repetitive reverse blocking voltage; defines usable input voltage headroom in boost/flyback topologies |
| IF | 16 A - Continuous average forward current at case temperature ≤75°C; determines heatsink sizing in steady-state operation |
| IFSM | 125 A - Non-repetitive surge current (8.3ms half-sine); withstands inrush and transient overloads without failure |
| trr | 35 ns - Reverse recovery time; minimizes switching losses and EMI in high-frequency SMPS designs |
| VF | 1.300 V @ 8A, 25°C - Forward voltage drop per diode; directly impacts conduction loss and thermal design |

Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1603S | 16A, 300V, 35ns trr, TO-220AC package (single anode), RθJC = 1.7°C/W | Single-die construction; no dual-anode flexibility; slightly higher thermal resistance | Preferred where board layout uses single-input rectification and cost sensitivity outweighs dual-die benefits |
| IXYS MUR1630CT | 16A, 300V, 35ns trr, TO-220AB, dual common-cathode but higher VF (1.45V typ) | Same pinout but higher conduction loss; not AEC-Q101 qualified in standard grade | Consider when existing PCB uses identical footprint and thermal margin exists for extra 0.15V drop |
Compared with STTH1603S and IXYS MUR1630CT, the SF1605G offers dual-anode flexibility in TO-220AB, lower VF than MUR1630CT, and AEC-Q101 availability-making it optimal for space-constrained, high-reliability dual-path or automotive designs.

FAQ
What is the maximum repetitive peak reverse voltage rating for SF1605G?
The SF1605G has a VRRM of 300 V, confirmed in the Absolute Maximum Ratings table for the SF1605G row. This value is fixed per part number and distinct from other members of the SF1601G–SF1608G family, which span 50V to 600V. The SF1605G is not rated for 400V or higher reverse conditions.
Is SF1605G pin-compatible with SF1605GH?
Yes, SF1605G and SF1605GH share identical TO-220AB mechanical dimensions, pinout, and electrical specifications. The "H" suffix denotes AEC-Q101 qualification; all other parameters-including VRRM, IF, trr, and thermal resistance-are identical between SF1605G and SF1605GH.
What is the forward voltage of SF1605G under typical operating conditions?
The SF1605G exhibits a typical forward voltage of 1.300 V at IF = 8 A and TJ = 25°C, as specified in the Electrical Specifications table. At higher junction temperatures or currents, VF decreases slightly due to negative temperature coefficient, but remains within 1.45 V max across full operating range.
Does SF1605G have a common-cathode or common-anode configuration?
The SF1605G uses a common-cathode configuration: Lead 2 (center) is the shared cathode, while Leads 1 and 3 are independent anodes. This dual-anode, single-cathode arrangement supports center-tapped transformer outputs, dual-output supplies, or interleaved rectification without external wiring.
What thermal performance data is available for SF1605G?
SF1605G has a junction-to-case thermal resistance (RθJC) of 1.5°C/W, measured under standard mounting conditions. This value assumes proper heatsink contact and mounting torque ≤0.56 N·m. Case temperature must be maintained ≤75°C to sustain 16A IF, per the Forward Current Derating Curve.
