Diodes Incorporated S1BB-13-F

Overview

S1BB-13-F from Diodes Incorporated is a surface-mount, glass-passivated silicon rectifier diode in SMB package, rated for 100 V peak repetitive reverse voltage (VRRM), 1.0 A average forward current (IO), and 30 A non-repetitive surge current (IFSM). It serves as a general-purpose AC-to-DC conversion device in power supplies and input stage rectification for industrial and consumer electronics.

For engineers reviewing the S1BB-13-F datasheet, S1BB-13-F pinout, S1BB-13-F application, or S1BB-13-F equivalent, key selection criteria include its 1.1 V max forward voltage at 1.0 A, 100 µA max reverse leakage at +125°C, 3.0 µs max reverse recovery time, SMB thermal resistance of 30°C/W, and RoHS-compliant matte tin plating.

Technical Context

This SMB-packaged rectifier operates in single-phase, half-wave configurations with resistive or inductive loads at 60 Hz. Its glass-passivated die construction ensures high reliability under thermal cycling and humidity exposure, while the cathode band polarity marking enables unambiguous PCB orientation during automated assembly.

The device exhibits a typical junction-to-terminal thermal resistance of 30°C/W when mounted on a 5.0 mm² copper pad, supporting continuous operation up to +150°C junction temperature. Reverse recovery time is specified at 1.8–3.0 µs under IF = 0.5 A, IR = 1.0 A, IRR = 0.25 A conditions-suitable for medium-frequency switching applications below 100 kHz.

FAQ

What is the maximum junction temperature for S1BB-13-F?

The maximum junction temperature (TJ) is +150°C, verified per DS16003 Rev. 24-2. This rating applies across the full operating range and supports use in enclosed enclosures with limited airflow, provided thermal resistance to ambient remains within design limits calculated using RθJT = 30°C/W and PCB copper area.

Is S1BB-13-F suitable for full-wave bridge configurations?

Yes-S1BB-13-F is commonly used as one quadrant in discrete full-wave bridge rectifiers. Its SMB package, 100 V VRRM, and 1.0 A IO rating match standard bridge requirements for 120 VAC inputs. Four units can be assembled into a compact surface-mount bridge with shared thermal plane for improved power density.

Does S1BB-13-F require derating for capacitive loads?

Yes-per DS16003, average forward current must be derated by 20% when used with capacitive loads due to increased peak current stress. For a 1.0 A rated device, this means limiting continuous IO to 0.8 A in capacitor-input filter applications to ensure reliability and avoid premature failure.

How is polarity identified on S1BB-13-F?

Polarity is marked by a visible cathode band on the body end of the SMB package. The band aligns with the cathode terminal, which must connect toward the positive side of the DC output. This marking is consistent across Diodes Incorporated's S1x-B series and matches IPC-7351 polarity conventions for automated optical inspection.
