Diodes Incorporated ES2C-13-F

Overview

ES2C-13-F from Diodes Incorporated is a 150 V, 2.0 A surface-mount super-fast rectifier diode in SMB package, featuring 25 ns reverse recovery time, 0.92 V forward voltage at 2.0 A, and 50 A non-repetitive surge rating - deployed in AC/DC front-end rectification for compact power adapters and DC-DC converter input stages.

For engineers reviewing the ES2C-13-F datasheet, ES2C-13-F pinout, ES2C-13-F application, or ES2C-13-F equivalent, key selection criteria include peak repetitive reverse voltage (150 V), average rectified current (2.0 A at T_T = 110°C), thermal resistance (20 °C/W), reverse recovery time (25 ns), and RoHS-compliant matte tin plating on SMB terminals.

Technical Context

This SMB-packaged super-fast rectifier uses glass-passivated die construction to achieve stable junction performance under repetitive switching stress. Its 25 ns trr and low 0.92 V V_F at 2.0 A support high-frequency operation in offline SMPS and flyback converters where conduction loss and switching loss trade-offs are critical.

The device operates across –55°C to +150°C with 20 °C/W typical junction-to-terminal thermal resistance when mounted on 5.0 mm² copper pads. It sustains 50 A single-half-sine surge (8.3 ms) and exhibits only 5.0 μA peak reverse current at 25°C and rated 150 V DC blocking voltage.

Key Specifications

Pinout & Package

SMB (DO-214AA) surface-mount plastic package with cathode band polarity marking; dimensions: 3.30–3.94 mm (L) × 4.06–4.57 mm (W) × 1.96–2.21 mm (H); weight ≈ 0.093 g.

FAQ

What is the maximum allowable junction temperature for ES2C-13-F?

The absolute maximum junction temperature is +150°C, aligned with its storage temperature rating. Derating begins at terminal temperature >110°C, where average forward current drops linearly to zero. Thermal design must ensure R_θJT × P_D + T_T ≤ 150°C under worst-case load and ambient conditions.

Does ES2C-13-F support lead-free reflow soldering?

Yes - ES2C-13-F features matte tin lead-free plating qualified to MIL-STD-202 Method 208 and compatible with standard Pb-free reflow profiles (peak 260°C, 10 s max). Its SMB package meets J-STD-020 Level 1 moisture sensitivity, eliminating bake requirements prior to assembly.

How does the 25 ns reverse recovery time impact EMI in switching supplies?

A 25 ns t_rr reduces reverse recovery di/dt and associated high-frequency ringing on drain-source nodes, lowering conducted EMI in the 30–100 MHz band. This enables simpler EMI filter design and helps meet CISPR-32 Class B limits without additional snubbers in sub-100 W flyback converters.

Can ES2C-13-F replace ES2B-13-F in an existing design?

Yes - both share identical SMB package, pinout, thermal characteristics, and surge rating. ES2C-13-F offers higher V_RRM (150 V vs. 100 V) and slightly higher V_F (0.92 V vs. 0.87 V at 2.0 A), enabling direct upgrade in 277 VAC or high-line designs where extra voltage margin is needed without layout change.
