Diodes Incorporated SK16-13-F

Overview

SK16-13-F from Diodes Incorporated is a surface-mount Schottky barrier rectifier rated for 60 V maximum recurrent peak reverse voltage, 1.0 A average forward rectified current at 75°C, and 25 A non-repetitive peak surge current (8.3 ms half-sine), used in DC/DC converter output stages and low-voltage AC-DC adapters.

For engineers reviewing the SK16-13-F datasheet, SK16-13-F pinout, SK16-13-F application, or SK16-13-F equivalent, key selection criteria include VF @ 1.0A (0.70 V max), IR @ 25°C (0.5 mA max), thermal resistance (25 °C/W junction-to-lead), SMB package compatibility, and RoHS-compliant matte tin plating.

Technical Context

This Schottky rectifier employs a high-temperature metallurgically bonded junction to achieve low forward voltage drop and fast switching with no minority-carrier storage delay. Its 60 V V_RRM rating supports 48 V system rails and PoE-powered devices.

Designed for surface-mounted applications with 2.0–2.62 mm cathode band width and 5.0–6.0 mm body length, it operates across –65°C to +125°C junction temperature and withstands 265°C solder bath immersion for 10 seconds.

FAQ

Is SK16-13-F suitable for synchronous rectification control schemes?

No. SK16-13-F is a passive Schottky rectifier, not a MOSFET-based synchronous rectifier controller or driver. It functions as a two-terminal diode and cannot be actively gated. For synchronous rectification, discrete MOSFETs with gate drivers or integrated SR controllers (e.g., AP3410, MP6908) are required.

What is the maximum allowable PCB pad temperature during reflow soldering?

The SK16-13-F is rated for 265°C for 10 seconds in a solder bath, consistent with IPC/JEDEC J-STD-020C Level 1 moisture sensitivity. Reflow peak temperature must not exceed 260°C for ≤ 30 seconds, with ramp rates per JEDEC standards to avoid package cracking or delamination.

Does SK16-13-F have a specified reverse recovery time (t_rr)?

No t_rr is specified because SK16-13-F is a Schottky barrier device with majority-carrier conduction. It exhibits zero reverse recovery charge (Q_rr = 0) and no recovery tail, eliminating switching losses associated with PN-junction diodes like 1N4007 or UF4007.

Can SK16-13-F replace SK15-13-F in an existing design?

Yes, SK16-13-F is a direct upgrade from SK15-13-F (50 V V_RRM) with identical SMB package, pinout, and thermal characteristics, offering 20% higher reverse voltage margin. No layout or thermal changes are needed, and VF/IR specs remain compatible at shared operating currents.
