Diodes Incorporated ES2C-13

Overview

ES2C-13 from Diodes Incorporated is a 150 V peak repetitive reverse voltage, 2.0 A average rectified current, glass-passivated super-fast recovery surface-mount rectifier in SMA package with 25 ns reverse recovery time and 0.92 V forward voltage at 2.0 A. It serves as primary AC/DC input stage rectifier in compact offline power supplies for consumer adapters and industrial SMPS.

For engineers reviewing the ES2C-13 datasheet, ES2C-13 pinout, ES2C-13 application, or ES2C-13 equivalent, key selection criteria include VRRM derating for capacitive loads, thermal resistance (20 °C/W) under PCB copper pad heatsinking, surge rating (50 A @ 8.3 ms), and RoHS-compliant matte tin plating compatibility with lead-free reflow.

Technical Context

This super-fast rectifier uses a glass-passivated silicon die optimized for high-efficiency switching power conversion, where low trr minimizes switching losses during turn-off in flyback and forward converters. Its 25 ns recovery time enables operation up to several hundred kHz without excessive diode-induced ringing or EMI.

The device operates across –55 °C to +150 °C junction temperature range and exhibits stable reverse leakage (5.0 µA @ 25 °C, 350 µA @ 125 °C) under rated DC blocking voltage. Thermal resistance of 20 °C/W assumes mounting on 5.0 mm² × 0.013 mm thick copper pads - critical for maintaining IO = 2.0 A at TT = 110 °C.

FAQ

What is the maximum allowable ambient temperature for ES2C-13 at full 2.0 A load?

The device specifies IO = 2.0 A at terminal temperature TT = 110 °C, not ambient. With RθJT = 20 °C/W and typical PCB heatsinking, ambient must be ≤90 °C to maintain TT ≤ 110 °C. Derating curves (Figure 1) show 1.5 A max at 125 °C ambient.

Can ES2C-13 replace a standard FR107 in an existing design?

Yes, if the circuit requires ≥150 V VRRM and benefits from faster recovery. ES2C-13 has lower VFM (0.92 V vs. ~1.1 V) and much shorter trr (25 ns vs. ~500 ns), reducing switching loss. However, verify layout thermal relief and ensure cathode band orientation matches.

Is ES2C-13 suitable for use in a capacitive-input filter configuration?

No - the datasheet explicitly states "For capacitive load, derate current by 20%." At full 2.0 A, this requires limiting to 1.6 A average output current to avoid overstressing the junction due to high peak charging currents and associated thermal cycling.

Does ES2C-13 meet automotive AEC-Q101 qualification?

No - ES2C-13 is not AEC-Q101 qualified. It is rated for industrial temperature range (–55 °C to +150 °C), but lacks the stress testing, failure analysis, and traceability required for automotive applications. Use automotive-grade alternatives like SB2100 or MURS220 for such use cases.
