Taiwan Semiconductor Corporation SF1602G

Overview

SF1602G from Taiwan Semiconductor is a 16A, 100V super fast recovery rectifier diode in TO-220AB package, featuring 35ns reverse recovery time, 0.975V forward voltage at 8A/25°C, and 125A surge current capability. It serves as a primary output rectifier in high-frequency DC-DC converters requiring low conduction loss and fast switching.

For engineers reviewing the SF1602G datasheet, SF1602G pinout, SF1602G application, or SF1602G equivalent, key selection criteria include V_RRM=100V, I_F=16A, t_rr=35ns, thermal resistance R_θJC=1.5°C/W, and AEC-Q101 qualification availability (SF1602GH variant).

Technical Context

The SF1602G employs dual-die construction in a single TO-220AB case, enabling high-current handling with symmetrical thermal distribution. Its super fast recovery performance (t_rr ≤ 35ns) minimizes switching losses in 50–500 kHz SMPS topologies.

Designed for unidirectional conduction, it operates with junction temperatures from –55°C to +150°C and supports repetitive peak reverse voltage up to 100V. The device exhibits low junction capacitance (80 pF at 4V, 1MHz), supporting stable high-frequency operation without excessive capacitive loading.

FAQ

What is the maximum junction temperature rating for SF1602G?

The SF1602G has a maximum junction temperature (T_J) rating of +150°C, allowing reliable operation in high-ambient environments such as enclosed power supplies or under-hood automotive locations. This rating is maintained across its full current and voltage operating range, and derating curves confirm usable current down to –55°C storage temperature. Thermal design must respect R_θJC = 1.5°C/W to avoid exceeding this limit.

Is SF1602G pin-compatible with other devices in the SF160xG series?

Yes, all SF1601G through SF1608G share identical TO-220AB mechanical dimensions, pinout (anode–cathode–tab), and thermal interface. The only differences are V_RRM (50–600V) and corresponding V_F/C_J values. This allows direct substitution within the same voltage class without PCB changes, provided thermal and electrical margins remain acceptable for the target application.

Does SF1602G meet automotive qualification standards?

The base SF1602G is not AEC-Q101 qualified, but the SF1602GH variant is fully AEC-Q101 certified for automotive use. Both share identical electrical and thermal specifications; the 'H' suffix denotes additional stress testing per AEC-Q101 Rev D, including temperature cycling, highly accelerated life testing, and unbiased highly accelerated stress testing. SF1602GH is recommended for engine control, body electronics, and ADAS auxiliary power designs.

What is the typical forward voltage drop of SF1602G at rated current?

The SF1602G exhibits a typical forward voltage (V_F) of 0.975 V at 8 A and 25°C, measured under pulsed conditions (PW = 0.3 ms). At full rated average current (16 A), V_F rises to approximately 1.15 V due to self-heating. This low V_F directly reduces conduction losses compared to standard fast recovery diodes, improving overall converter efficiency by 0.5–1.2% in typical 100–300W designs.

How does SF1602G's reverse recovery time compare to standard fast rectifiers?

The SF1602G achieves a reverse recovery time (t_rr) of ≤35 ns under standardized test conditions (I_F = 0.5 A, I_R = 1.0 A, I_rr = 0.25 A), which is 40–60% faster than conventional fast recovery rectifiers (typically 60–100 ns). This enables cleaner switching waveforms, reduced EMI, and higher usable switching frequencies in SMPS designs without requiring snubber networks or complex gate drive timing adjustments.
