Diodes Incorporated ES3B-13-F

Overview

ES3B-13-F from Diodes Incorporated is a 3.0A surface-mount super-fast rectifier diode in SMC package, rated for 100V peak repetitive reverse voltage (VRRM), 0.9V max forward voltage at 3.0A, and 25ns reverse recovery time - optimized for high-frequency switching power supplies and DC/DC converters in industrial and consumer power systems.

For engineers reviewing the ES3B-13-F datasheet, ES3B-13-F pinout, ES3B-13-F application, or ES3B-13-F equivalent, key selection criteria include its 100V blocking capability, 100A non-repetitive surge rating, thermal resistance (RθJT = 10°C/W), RoHS-compliant matte tin plating, and suitability for automated SMT assembly on PCBs with 5.0 mm² copper pads.

Technical Context

This super-fast rectifier employs glass-passivated die construction to ensure stable junction performance under thermal cycling and high dv/dt stress. Its 25ns reverse recovery time (measured at IF = 0.5A, IR = 1.0A, IRR = 0.25A) enables efficient operation in 100–500 kHz SMPS topologies without excessive switching loss or EMI generation.

The device operates across –55°C to +150°C junction temperature range, with RθJA = 50°C/W (on 5.0 mm² Cu pad) and RθJT = 10°C/W, supporting high-power-density designs where thermal management is constrained. Polarity is indicated by cathode band marking on the SMC case.

Key Specifications

Pinout & Package

ES3B-13-F uses the SMC (DO-214AB) surface-mount package: molded plastic case (UL 94V-0), cathode band polarity marking, matte tin-plated terminals solderable per MIL-STD-202 Method 208, and moisture sensitivity level 1.

Equivalent & Alternatives

The following parts are listed as comparable options for similar super-fast rectifier applications.

Compared with STTH3L06S and MBR3100CT, ES3B-13-F delivers optimal balance of 100V rating, 25ns speed, SMC compactness, and 0.9V forward drop - making it ideal for space-constrained, medium-voltage, high-frequency rectification where Schottky leakage or slower recovery would degrade performance.

FAQ

What is the maximum junction temperature for ES3B-13-F?

The absolute maximum junction temperature is +150°C, with continuous operation permitted from –55°C to +150°C. Derating begins above +100°C terminal temperature, where average forward current drops linearly to zero at +150°C per Figure 1 in DS14003 Rev. 16-2.

Is ES3B-13-F suitable for automotive applications?

ES3B-13-F itself is not AEC-Q101 qualified; however, Diodes offers automotive-grade variants (e.g., ES3BQ-13-F) with PPAP documentation, IATF 16949 manufacturing, and extended temperature screening. Standard ES3B-13-F may be used in non-safety-critical automotive subsystems subject to customer qualification.

How does the SMC package compare to SMB for ES3B-13-F?

ES3B-13-F uses the larger SMC (DO-214AB) package - 6.22 × 7.11 × 2.75 mm - offering higher thermal mass and 3.0A current rating. The SMB variant (ES3BB-13-F) is smaller (2.5 × 5.59 × 2.21 mm) and rated for 2.0A; both share identical electrical specs except for thermal and current limits.

Can ES3B-13-F replace a standard FR304 diode?

Yes - ES3B-13-F matches FR304's 100V VRRM and 3A IO rating but improves performance with 25ns tRR (vs. 500ns for FR304) and 0.9V VFM (vs. 1.3V). This reduces switching loss and heat generation, enabling higher-frequency operation and smaller heatsinks in upgraded designs.
