Diodes Incorporated SB160-T

Overview

SB160-T from Diodes Incorporated is a 1.0A, 60V Schottky barrier rectifier in DO-41 package with 0.70V forward voltage at 1.0A, 40A non-repetitive surge capability, and guard ring die construction for transient protection-used in low-voltage DC/DC converter output rectification and polarity protection circuits.

For engineers reviewing the SB160-T datasheet, SB160-T pinout, SB160-T application, or SB160-T equivalent, key selection criteria include its 60V reverse blocking rating, low 0.70V V_F at rated current, DO-41 thermal resistance (R_θJL = 15°C/W), and RoHS-compliant bright tin-plated leads suitable for automated tape-and-reel assembly.

Technical Context

This discrete Schottky diode operates as a unidirectional power rectifier with metal-semiconductor junction architecture enabling low forward conduction loss and fast switching recovery-critical for high-frequency (>100 kHz) flyback and buck converter outputs. Its guard ring die structure enhances ruggedness against voltage transients without external snubbers.

Rated for continuous operation from –65°C to +125°C junction temperature, it delivers stable 1.0A average forward current under lead-temperature-limited conditions (9.5 mm from case), with thermal derating above 75°C ambient per Figure 1 in DS23022 Rev. 6-2.

FAQ

What is the maximum junction temperature for SB160-T?

The SB160-T has a maximum junction temperature of +125°C under continuous operation, as specified in DS23022 Rev. 6-2. Derating begins at +75°C lead temperature per Figure 1, and the device remains functional up to +150°C for short-term storage only.

Is SB160-T compatible with lead-free reflow soldering processes?

Yes-SB160-T features bright tin-plated leads compliant with J-STD-020C and qualified for peak reflow temperatures up to 260°C. Its DO-41 package withstands standard Pb-free thermal profiles without delamination or solder joint voiding.

How does SB160-T differ from SB150-T in practical design?

SB160-T offers 60V V_RRM versus SB150-T's 50V, enabling use in 24V systems exposed to ISO 16750-2 load-dump transients (up to 60V). Both share identical 1.0A I_O, 0.70V V_FM, and DO-41 packaging-no layout changes required for upgrade.

Can SB160-T replace a standard PN rectifier like 1N4007?

No-SB160-T is not a drop-in replacement for 1N4007. While both are DO-41 diodes, SB160-T has lower V_F (0.70V vs. 1.1V) but lower V_RRM (60V vs. 1000V) and higher IR_M; it is unsuitable for 100–1000V AC line rectification but superior in low-voltage, high-efficiency DC/DC stages.
