Diodes Incorporated S1GB-13-F

Overview

S1GB-13-F from Diodes Incorporated is a surface-mount, glass-passivated general-purpose silicon rectifier diode rated for 1.0A average forward current and 400V peak repetitive reverse voltage (VRRM), with 30A non-repetitive surge capability and 1.1V max forward voltage at 1.0A. It is used in AC/DC input stage rectification for power supplies, adapters, and industrial control modules where reliability under transient stress is required.

For engineers reviewing the S1GB-13-F datasheet, S1GB-13-F pinout, S1GB-13-F application, or S1GB-13-F equivalent, key selection criteria include its SMA package thermal resistance (30°C/W), 3.0μs max reverse recovery time, 10pF typical junction capacitance, and RoHS-compliant lead-free plating suitable for automated reflow assembly.

Technical Context

This device operates as a unidirectional, single-phase half-wave rectifier with glass-passivated junction construction ensuring high moisture resistance and long-term stability under thermal cycling. Its 400V VRRM rating supports universal-input (85–265VAC) front-end designs, while the 30A IFSM rating enables robustness against line surges and inrush events.

The diode exhibits soft reverse recovery behavior (trr ≤ 3.0μs), minimizing switching noise in low-frequency rectification circuits. Junction-to-terminal thermal resistance of 30°C/W-measured on a 5.0mm² copper pad-enables reliable operation up to +100°C case temperature without forced cooling.

FAQ

What is the maximum operating temperature for S1GB-13-F?

The S1GB-13-F has an operating junction temperature range of –65°C to +150°C. Its average forward current rating drops to 1.0A only when the terminal temperature is maintained at +100°C; derating is required above that point per Figure 1 in DS16003. The device remains functional up to +150°C junction, but sustained operation above +125°C requires careful thermal design.

Is S1GB-13-F suitable for use in a full-wave bridge configuration?

Yes-S1GB-13-F can be used in discrete full-wave bridge rectifiers. Four units provide 400V PIV capability and 1.0A DC output. However, its 3.0μs reverse recovery time makes it appropriate only for 50/60Hz or low-frequency (<1kHz) applications; fast-switching bridges require ultrafast diodes like MUR140.

Does S1GB-13-F have a specified reverse recovery charge (Qrr)?

No-Qrr is not specified in DS16003 Rev. 24. The datasheet provides only trr (≤3.0μs) measured under defined conditions (IF = 0.5A, IR = 1.0A, IRR = 0.25A). For designs requiring Qrr data-such as high-efficiency PFC stages-engineers should consult Diodes Incorporated's application notes or select a part with published Qrr, like the SB140.

Can S1GB-13-F replace S1G in existing designs?

Yes-S1GB-13-F is the tape-and-reel packaged, RoHS-compliant version of S1G. Both share identical electrical specs, SMA package dimensions, and marking code (S1G). The "B" suffix denotes halogen/antimony-free "Green" construction, and "-13-F" indicates 5,000-piece reel packaging with lead-free finish.
