Diodes Incorporated ES3AB-13-F

Overview

ES3AB-13-F from Diodes Incorporated is a 100 V, 3.0 A surface-mount super-fast rectifier in SMB package, featuring 25 ns reverse recovery time, 0.9 V forward voltage at 3.0 A, and 100 A non-repetitive surge rating - deployed in AC/DC front-end rectification for compact power adapters and DC-DC converter inputs.

For engineers reviewing the ES3AB-13-F datasheet, ES3AB-13-F pinout, ES3AB-13-F application, or ES3AB-13-F equivalent, key selection criteria include peak repetitive reverse voltage (100 V), thermal resistance (10 °C/W junction-to-terminal), RoHS-compliant lead-free plating, and SMB package compatibility with automated SMT assembly lines.

Technical Context

This super-fast rectifier uses glass-passivated die construction to achieve stable switching performance under high-frequency operation. Its 25 ns reverse recovery time minimizes switching losses in 50–500 kHz SMPS topologies, while the 100 A surge rating supports transient line-event robustness in universal-input offline converters.

The device operates across –55 °C to +150 °C with a typical junction-to-terminal thermal resistance of 10 °C/W, enabling direct PCB copper pad heatsinking without auxiliary thermal vias. Its 45 pF junction capacitance at 4.0 V reverse bias supports low-noise EMI behavior in high-dV/dt environments.

FAQ

What is the maximum junction temperature for ES3AB-13-F?

The absolute maximum junction temperature is +150 °C, with continuous operation supported from –55 °C to +150 °C. Derating begins at terminal temperatures above +100 °C per the forward current derating curve (Figure 1), where IO drops linearly to zero at +150 °C terminal temperature.

Is ES3AB-13-F qualified for automotive applications?

ES3AB-13-F is not AEC-Q101 qualified by default. Diodes Incorporated offers automotive-grade variants (e.g., ES3AB-13-F-A) with PPAP documentation, IATF 16949 manufacturing, and extended temperature screening - contact Diodes or Aetrix for qualified part numbers and qualification reports.

How does the SMB package compare thermally to SMC for this device?

The SMB package has higher thermal resistance than SMC: RθJT is 10 °C/W for both, but RθJA is 50 °C/W for SMB versus ~35 °C/W for SMC due to larger copper pad area. SMB requires ≥4.3 mm × 2.3 mm minimum copper pad (per suggested layout) to sustain 3.0 A at +100 °C terminal temperature.

Can ES3AB-13-F replace a standard FR307 rectifier?

No - FR307 is a 1000 V, 3 A fast rectifier with ~500 ns tRR and TO-220 package. ES3AB-13-F's 100 V rating and 25 ns tRR make it unsuitable for high-voltage line rectification. It replaces devices like ES1J or MUR110 in low-voltage, high-frequency applications where speed and efficiency are prioritized over voltage headroom.
