Diodes Incorporated S1AB-13-F

Overview

S1AB-13-F from Diodes Incorporated is a 1.0A, 100V glass passivated surface-mount rectifier diode in SMB package, featuring 30A non-repetitive surge rating, 1.1V max forward voltage at 1.0A, and 5.0μA max reverse leakage at 25°C - used for AC/DC input rectification in compact power supplies and adapter circuits.

For engineers reviewing the S1AB-13-F datasheet, S1AB-13-F pinout, S1AB-13-F application, or S1AB-13-F equivalent, this part supports high-reliability, automated assembly in commercial-grade power conversion where thermal resistance (30°C/W), fast recovery (1.8–3.0μs), and RoHS-compliant lead-free plating are critical selection criteria.

Technical Context

This SMB-packaged silicon rectifier operates as a unidirectional current-conducting device in single-phase, half-wave configurations with resistive or inductive loads. Its glass passivated die construction ensures stable junction performance under thermal cycling and humidity exposure.

The diode exhibits a typical reverse recovery time of 1.8μs (max 3.0μs) under IF = 0.5A / IR = 1.0A conditions and delivers 10pF typical junction capacitance at 1.0MHz and 4.0V reverse bias - enabling efficient operation in 50/60Hz and low-frequency switching applications.

FAQ

What is the difference between S1AB-13-F and S1A-13-F?

S1AB-13-F uses the larger SMB (DO-214AA) package with higher thermal mass and 0.093g weight, whereas S1A-13-F uses the smaller SMA (DO-214AC) package (0.064g). Both share identical electrical specs (100V VRRM, 1.0A IO), but SMB offers lower thermal resistance and better surge energy absorption due to greater copper pad contact area.

Can S1AB-13-F replace a 1N4007 in new designs?

No - S1AB-13-F has 100V VRRM versus 1N4007's 1000V rating. It is not a drop-in replacement for high-voltage applications. However, it is a superior choice for 100V-rated, space-constrained, surface-mount designs requiring lower VF, faster trr, and RoHS compliance compared to through-hole 1N400x series.

Is S1AB-13-F suitable for high-frequency switching applications?

No - with a reverse recovery time of 1.8–3.0μs, S1AB-13-F is optimized for 50/60Hz and low-frequency (<1kHz) rectification. For high-frequency SMPS (>20kHz), fast recovery or Schottky diodes with trr < 100ns are required to minimize switching losses and EMI.

Does S1AB-13-F require derating for capacitive loads?

Yes - per datasheet, average forward current must be derated by 20% when used with capacitive-input filter stages. At full 1.0A rating, the device assumes resistive or inductive loading; for capacitor-input supplies, maximum continuous IO is limited to 0.8A to prevent thermal runaway during cold-start surges.
