Diodes Incorporated ES2B-13-F

Overview

ES2B-13-F from Diodes Incorporated is a 2.0 A surface-mount super-fast rectifier in an SMB package. It is designed for high-efficiency rectification where reverse recovery speed, surge capability, and automated surface-mount assembly are important for compact power electronics.

For engineers reviewing the ES2B-13-F datasheet, ES2B-13-F pinout, ES2B-13-F application, or ES2B-13-F equivalent, this diode is most relevant for switching power supplies, DC-DC converters, fast rectifier paths, freewheel circuits, adapter boards, industrial control boards, and consumer power products requiring 100 V reverse-voltage class, 2 A rectification, fast recovery behavior, and SMB package assembly.

Technical Context

ES2B-13-F is a super-fast rectifier, so its key design role is not only blocking reverse voltage and conducting forward current, but also recovering quickly when the circuit commutates. In switching converters, slow diode recovery can create extra switching loss, heat, ringing, and EMI stress. A fast rectifier reduces those effects when the diode is repeatedly driven from conduction to blocking state.

The SMB package gives ES2B-13-F more current and thermal handling capability than many small signal-diode packages while remaining suitable for automated surface-mount assembly. Designers still need to check copper area, surge current, and repetitive thermal cycling because forward conduction loss rises with current and duty cycle.

Key Specifications

Pinout & Package

ES2B-13-F uses an SMB two-terminal surface-mount rectifier package. The package has an anode and cathode orientation that must match the rectifier direction in the schematic and PCB footprint. The SMB body gives practical solder-joint area and thermal contact for 2 A class rectifier use.

Key Features

• 2.0 A surface-mount super-fast rectifier.
• 100 V reverse-voltage class for low- and mid-voltage power paths.
• Fast recovery behavior for switching power-supply efficiency.
• 50 A peak surge overload rating for short non-repetitive events.
• Glass-passivated die construction.
• SMB package suited to automated assembly.
• Lead-free / RoHS-compliant finish.
• Green molding compound without halogen and antimony.

Applications

Equivalent & Alternatives

When evaluating ES2B-13-F equivalent devices, engineers should compare reverse voltage, average current, surge rating, reverse-recovery time, forward voltage, SMB footprint, polarity, thermal resistance, and whether the original circuit needs super-fast recovery rather than a standard rectifier characteristic.

Quality

ES2B-13-F should be sourced as original Diodes Incorporated rectifiers through traceable and controlled supply channels. Quality verification procedures may include SMB package inspection, cathode-band orientation review, reel label inspection, solderability testing, forward-voltage screening, reverse-leakage testing, surge-risk review, moisture sensitivity handling verification, and incoming inspection suited to surface-mount rectifier production.

Availability

ES2B-13-F is available at Aetrix Electronics and suitable for switching power supplies, DC-DC converters, freewheel circuits, clamp paths, adapter boards, industrial control boards, appliance power boards, and repair programs requiring a 100 V, 2 A super-fast rectifier in SMB package form.

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

For production deployment, confirming the SMB footprint, cathode orientation, reverse-voltage margin, current waveform, recovery requirement, surge exposure, copper area, soldering process, and sourcing continuity helps reduce converter reliability and assembly risk.

FAQ

What is ES2B-13-F used for?

ES2B-13-F is used as a 2 A surface-mount super-fast rectifier in switching power supplies, converters, snubber-related paths, freewheel circuits, and general high-efficiency rectification. Its 100 V reverse-voltage class and fast recovery behavior suit circuits where ordinary slow rectifiers would waste switching energy.

What package does ES2B-13-F use?

ES2B-13-F uses an SMB surface-mount package. The package supports automated assembly and provides more thermal and current capability than very small signal-diode packages, making ES2B-13-F practical for moderate-current rectification on compact power boards.

What reverse voltage rating does ES2B-13-F provide?

ES2B-13-F provides a 100 V repetitive peak reverse-voltage class. Designers should compare this rating with steady reverse voltage, supply tolerance, transformer or inductor ringing, and transient conditions so the rectifier has enough margin in the final application.

Why is ES2B-13-F called a super-fast rectifier?

ES2B-13-F is called a super-fast rectifier because it is designed for short reverse-recovery time compared with standard rectifiers. This behavior reduces switching loss and reverse-recovery stress in power converters, especially where the diode commutates at high frequency.

What current rating does ES2B-13-F support?

ES2B-13-F is a 2 A class rectifier. The usable current in a board depends on copper area, ambient temperature, duty cycle, waveform shape, package temperature, surge exposure, and whether the SMB package can dissipate the heat produced by forward conduction losses.

What are common ES2B-13-F alternatives?

Common ES2B-13-F comparison options include other ES2 series voltage ratings such as ES2A for lower reverse-voltage designs and ES2D for higher reverse-voltage margin. Any change requires checking package, polarity, recovery time, surge rating, and thermal performance in the circuit.
