Product details

Overview

SFS1606GH from Taiwan Semiconductor is a 16A, 400V repetitive peak reverse voltage (V_RRM) super fast surface-mount rectifier in TO-263AB (D2PAK) package, featuring 1.300V max forward voltage at 8A/25°C, 35ns reverse recovery time, and AEC-Q101 qualification for automotive-grade reliability in freewheeling and snubber circuits.

For engineers reviewing the SFS1606GH datasheet, SFS1606GH pinout, SFS1606GH application, or SFS1606GH equivalent, key selection criteria include its 400V V_RRM, dual-die configuration, 125A I_FSM surge rating, junction-to-case thermal resistance of 2.5°C/W, and compliance with J-STD-020 level-1 moisture sensitivity.

Technical Context

This device is a single-phase, dual-die super fast recovery rectifier optimized for high-frequency switching applications. Its 35ns trr and low Q_rr minimize switching losses in DC-DC converters and automotive lighting drivers.

The TO-263AB package enables high power dissipation with 2.5°C/W R_θJC, while AEC-Q101 qualification confirms robustness under automotive temperature cycling (-55°C to +150°C) and mechanical stress testing.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
Vishay VS-16EWH04-M3	Same 400V V_RRM, 16A I_F, but TO-220AC package; 50ns t_rr; no AEC-Q101 certification.	Requires larger PCB footprint and lacks automotive qualification; suitable for industrial-only designs.	Select when automotive qualification is not required and TO-220 mounting is preferred.
ON Semiconductor MUR1640CT	Dual common-cathode configuration, same 400V/16A ratings, 60ns t_rr, TO-220 package; AEC-Q101 not claimed.	Higher t_rr increases switching loss; different pinout prevents drop-in replacement.	Consider only if legacy board uses TO-220 and AEC-Q101 is waived.

Compared with VS-16EWH04-M3 and MUR1640CT, the SFS1606GH delivers faster recovery (35ns), automotive qualification, and superior thermal performance in D2PAK-making it optimal for space-constrained, high-reliability automotive power stages where EMI and thermal management are critical.

FAQ

What is the maximum repetitive peak reverse voltage (V_RRM) for SFS1606GH?

The SFS1606GH has a V_RRM of 400 V, as confirmed by the absolute maximum ratings table in the official Taiwan Semiconductor datasheet (Version A2103). This rating applies across the full operating junction temperature range (-55°C to +150°C) and defines the highest DC or peak AC reverse voltage the device can block without breakdown. It is distinct from lower-voltage variants like SFS1605GH (300V) and higher-voltage variants like SFS1607GH (500V).

Is SFS1606GH qualified for automotive applications?

Yes, the SFS1606GH is explicitly AEC-Q101 qualified per the manufacturer's documentation. This qualification covers stress tests including temperature cycling, highly accelerated stress test (HAST), mechanical shock, and whisker resistance (JESD201 Class 2). The device is intended for use in automotive subsystems such as LED lighting, body control modules, and DC-DC converters where reliability under harsh environmental conditions is mandatory.

What is the forward voltage (V_F) specification for SFS1606GH at rated current?

The SFS1606GH has a maximum forward voltage of 1.300 V at 8 A and T_J = 25°C, as specified in the electrical characteristics table. This value is measured under pulsed conditions (PW = 0.3 ms) to avoid self-heating effects. At higher junction temperatures or continuous DC operation, V_F decreases slightly due to negative temperature coefficient behavior typical of silicon rectifiers.

Does SFS1606GH have a dual-die configuration, and how is it wired?

Yes, the SFS1606GH integrates two independent rectifier dies in a single TO-263AB (D2PAK) package with a common cathode configuration. The three terminals are Anode 1, Cathode (shared), and Anode 2. This layout supports full-wave rectification or parallel current sharing without external interconnects, reducing parasitic inductance and PCB area versus discrete dual-diode solutions.

What is the reverse recovery time (t_rr) of SFS1606GH, and under what test conditions is it measured?

The SFS1606GH has a maximum reverse recovery time of 35 ns, measured under the conditions IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A, per the electrical specifications table. This test uses a standardized double-pulse method defined in JEDEC standards and reflects performance in high-frequency switching applications such as 200–500 kHz DC-DC converters where fast turn-off minimizes switching loss and EMI generation.
