Diodes Incorporated S1DB-13-F

Overview

S1DB-13-F from Diodes Incorporated is a 1 A, 200 V standard recovery surface-mount rectifier in an SMB package. It is built for general-purpose AC-to-DC rectification, reverse-polarity protection, blocking, and freewheel paths where a compact 200 V diode is needed on an automated assembly line.

For engineers reviewing the S1DB-13-F datasheet, S1DB-13-F pinout, S1DB-13-F application, or S1DB-13-F equivalent, this part is most relevant for power adapters, appliance boards, industrial controls, auxiliary rectifier stages, protection inputs, and repair programs requiring 1 A rectified current, 200 V reverse-voltage capability, 30 A surge handling, and SMB surface-mount construction.

Technical Context

S1DB-13-F is a standard recovery rectifier, so its strongest fit is mains-derived or lower-frequency rectification rather than very high-frequency converter commutation. The device blocks reverse voltage in one half-cycle or off-state condition and conducts forward current during the allowed current path.

The SMB package gives more solderable area and thermal mass than miniature signal-diode packages while remaining compact enough for dense boards. In real designs, current capability depends on waveform duty cycle, copper area, ambient temperature, surge exposure, and how much reverse-recovery loss the circuit can tolerate.

Key Specifications

Pinout & Package

S1DB-13-F is a two-terminal SMB rectifier. The anode and cathode define the conduction direction, and the cathode band must match the PCB silkscreen and schematic symbol. A reversed part can turn a rectifier into a shorted or non-conducting power path, so polarity inspection is important.

Key Features

• 1 A standard recovery rectifier in SMB package.
• 200 V reverse-voltage class for general rectifier and blocking circuits.
• 30 A non-repetitive surge-current capability.
• 1.1 V maximum forward-voltage class for loss calculation.
• 1.8 µs recovery behavior suited to line-frequency and standard rectifier use.
• Compact surface-mount package for automated assembly.
• Useful for auxiliary supplies, reverse-polarity protection, and general blocking paths.
• Tape-and-reel ordering format for production handling.

Applications

Equivalent & Alternatives

When evaluating S1DB-13-F equivalent devices, compare reverse-voltage rating, average current, surge current, reverse-recovery behavior, SMB footprint, cathode orientation, forward-voltage loss, thermal conditions, and packing suffix requirements.

Quality

S1DB-13-F should be sourced as original Diodes Incorporated rectifiers through traceable and controlled supply channels. Quality checks may include SMB body inspection, cathode-band verification, reel label review, solderability testing, forward-voltage screening, reverse-leakage testing at the required voltage, surge-risk review, polarity inspection, and incoming inspection aligned with surface-mount rectifier production.

Availability

S1DB-13-F is available at Aetrix Electronics and suitable for AC-to-DC auxiliary rectification, reverse-polarity protection, blocking paths, freewheel circuits, industrial control boards, appliance boards, adapters, and repair programs requiring a 1 A, 200 V SMB standard rectifier.

Supply support may include scheduled delivery planning, volume procurement support, BOM continuity assistance, traceable sourcing management, and lifecycle availability coordination for power-supply manufacturers, appliance producers, industrial equipment builders, contract manufacturers, and repair organizations.

For production deployment, confirming the SMB footprint, cathode orientation, 200 V blocking margin, current waveform, surge exposure, standard recovery requirement, copper area, soldering process, and sourcing continuity helps reduce rectifier selection risk.

FAQ

What is S1DB-13-F used for?

S1DB-13-F is used for general-purpose rectification, reverse-polarity protection, blocking, and freewheel paths on compact power boards. The 1 A current class and 200 V reverse-voltage rating make S1DB-13-F useful in adapters, appliance controls, auxiliary supplies, and industrial board repair.

What package does S1DB-13-F use?

S1DB-13-F uses an SMB surface-mount package. This package gives the diode practical solder area and heat spreading for 1 A class rectifier work while fitting automated assembly flows. Board copper, pad geometry, cathode orientation, and reflow conditions still matter for S1DB-13-F reliability.

Is S1DB-13-F a fast recovery diode?

S1DB-13-F is a standard recovery rectifier, not an ultrafast switching rectifier. Its recovery behavior is appropriate for many line-frequency, auxiliary supply, protection, and blocking functions, but S1DB-13-F should be compared with fast or ultrafast parts in high-frequency converter nodes.

What voltage rating does S1DB-13-F provide?

S1DB-13-F provides a 200 V reverse-voltage class. The usable margin depends on steady reverse voltage, ringing, surge events, and supply tolerance in the finished product. Designers should leave enough headroom so S1DB-13-F is not operated close to breakdown during transients.

What should be checked before replacing S1DB-13-F?

Before replacing S1DB-13-F, check reverse-voltage rating, average and surge current, SMB footprint, cathode-band orientation, forward-voltage loss, recovery speed, leakage, operating temperature, soldering process, and whether the circuit depends on standard recovery behavior rather than Schottky or ultrafast characteristics.
