Diodes Incorporated B180-13-F

Overview

B180-13-F from Diodes Incorporated is a 1.0A, 80V peak repetitive reverse voltage (V_RRM) Schottky barrier rectifier in SMA package, featuring 0.79V max forward voltage at 1.0A and 0.5mA max reverse leakage at 25°C, used for polarity protection and freewheeling in DC-DC converters and low-voltage power supplies.

For engineers reviewing the B180-13-F datasheet, B180-13-F pinout, B180-13-F application, or B180-13-F equivalent, key selection criteria include its low VF for reduced conduction loss, guard ring die construction for transient robustness, RoHS-compliant lead-free finish, and JEDEC-qualified reliability for industrial and automotive-adjacent designs.

Technical Context

This Schottky rectifier uses a planar guard ring die structure to suppress edge breakdown and improve surge immunity under repetitive transients. Its low junction-to-terminal thermal resistance (25°C/W) enables reliable 1.0A average current handling at terminal temperatures up to +125°C.

It operates with minimal stored charge and zero minority-carrier recovery, making it suitable for high-frequency switching applications such as synchronous rectification in buck converters and flyback snubbers. Capacitance is specified at 80pF @ 4V, supporting predictable AC impedance behavior above 1MHz.

FAQ

What is the maximum junction temperature for B180-13-F?

The device supports continuous operation from −65°C to +150°C junction temperature. Derating begins at +125°C terminal temperature, where average forward current drops linearly to zero at +150°C per Figure 3 in DS30018 Rev. 15–2.

Is B180-13-F suitable for automotive applications?

Yes - the B180Q and B180BQ variants are AEC-Q200 qualified for automotive use. While B180-13-F is industrial-grade, its JEDEC qualification, guard ring die, and −65°C to +150°C rating support under-hood adjacent systems like infotainment power rails when validated per customer requirements.

How does B180-13-F compare to standard silicon rectifiers in efficiency?

At 1.0A, its 0.79V max VF yields ~0.79W conduction loss versus ≥1.1V for comparable silicon diodes - reducing heat generation by ≥300mW and improving converter efficiency by 2–4% in 5–12V output stages.

Can B180-13-F be used in parallel for higher current?

No - Schottky diodes exhibit negative temperature coefficient VF, causing current hogging. Parallel operation requires matched VF binning and external ballasting resistors; Diodes does not recommend or characterize B180-13-F for paralleling without individual thermal management.
