Diodes Incorporated ES2AA-13-F

Overview

ES2AA-13-F from Diodes Incorporated is a 50 V, 2.0 A surface-mount super-fast rectifier diode in SMA package, featuring 25 ns reverse recovery time, 0.92 V forward voltage at 2.0 A, and 50 A non-repetitive surge rating - used in AC/DC input stage of compact switch-mode power supplies.

For engineers reviewing the ES2AA-13-F datasheet, ES2AA-13-F pinout, ES2AA-13-F application, or ES2AA-13-F equivalent, key selection criteria include peak repetitive reverse voltage (50 V), thermal resistance (20 °C/W), RMS reverse voltage (35 V), capacitance (25 pF), and RoHS-compliant lead-free plating.

Technical Context

This super-fast rectifier employs glass-passivated die construction to achieve stable junction performance under high dv/dt conditions. Its 25 ns reverse recovery time minimizes switching losses in high-frequency converters operating up to several hundred kHz.

The device supports automated assembly via tape-and-reel packaging (5000 pcs/reel) and meets J-STD-020 moisture sensitivity Level 1. Cathode identification uses a band marking, and thermal management relies on PCB copper pads (5.0 mm², 0.013 mm thick) for junction-to-terminal conduction.

Key Specifications

Pinout & Package

FAQ

What is the maximum allowable junction temperature for ES2AA-13-F?

The absolute maximum junction temperature is +150°C, and the device is rated for continuous operation up to this limit when terminal temperature is maintained at ≤110°C per the derating curve. Thermal design must account for RθJT = 20 °C/W and PCB copper pad area (5.0 mm² minimum) to avoid exceeding TJ(max).

Is ES2AA-13-F compatible with lead-free reflow soldering processes?

Yes - ES2AA-13-F features matte tin lead-free plating and is qualified per J-STD-020 Level 1 moisture sensitivity. It supports standard Pb-free reflow profiles (peak 260°C), with no pre-bake required due to its Level 1 classification.

How does the 25 ns reverse recovery time impact EMI in a 200 kHz flyback converter?

A 25 ns trr limits high-frequency ringing during turn-off, reducing common-mode noise above 10 MHz. In a 200 kHz flyback, this suppresses harmonic energy near 40 MHz and beyond, easing compliance with CISPR-32 Class B conducted emissions limits without additional snubbing.

Can ES2AA-13-F replace a standard FR107 in an existing design?

Yes - ES2AA-13-F offers identical 50 V VRRM and 1 A IO (derated) but with 25 ns trr versus FR107's 500 ns, enabling higher switching frequencies and lower losses. Verify layout clearance for SMA vs. DO-41, and confirm cathode band orientation matches existing silkscreen.
