Diodes Incorporated ES3C-13

Overview

ES3C-13 from Diodes Incorporated is a 150 V, 3.0 A surface-mount super-fast rectifier in SMC package with 25 ns reverse recovery time, 0.9 V forward voltage at 3.0 A, and 100 A non-repetitive surge rating-used in high-frequency AC/DC adapters and switch-mode power supply output stages.

For engineers reviewing the ES3C-13 datasheet, ES3C-13 pinout, ES3C-13 application, or ES3C-13 equivalent, key selection criteria include peak repetitive reverse voltage (150 V), fast recovery performance (25 ns), thermal resistance (15 °C/W), RoHS-compliant lead-free plating, and SMC package compatibility with automated reflow assembly.

Technical Context

This super-fast rectifier employs glass-passivated die construction to achieve low forward voltage drop and stable switching behavior under high di/dt conditions. Its 25 ns reverse recovery time minimizes switching losses in 50–500 kHz SMPS topologies, while the 150 V V_RRM supports universal-input offline designs with margin.

The device operates across –65 °C to +150 °C junction temperature range and exhibits 45 pF typical junction capacitance at 4 V reverse bias-critical for EMI control in high-frequency rectification. Thermal resistance of 15 °C/W (junction-to-terminal) enables reliable operation at full 3.0 A average current with minimal PCB copper heatsinking (5 mm², 0.013 mm thick).

FAQ

What is the maximum junction temperature for continuous operation of ES3C-13?

The ES3C-13 has a specified operating junction temperature range of –65 °C to +150 °C. For continuous 3.0 A DC operation, thermal design must ensure junction temperature remains ≤150 °C using the 15 °C/W junction-to-terminal thermal resistance and appropriate PCB copper area (minimum 5 mm² per datasheet note 1).

Is ES3C-13 compatible with lead-free reflow soldering processes?

Yes-ES3C-13 features matte tin lead-free plating and is rated for lead-free reflow per J-STD-020C Level 1 moisture sensitivity. It withstands peak temperatures up to 260 °C for 30 seconds without degradation, meeting IPC/JEDEC standards for Pb-free assembly.

How does the 25 ns reverse recovery time impact EMI in high-frequency SMPS?

A 25 ns t_rr limits reverse recovery di/dt, reducing high-frequency ringing and common-mode noise generated during turn-off. This directly lowers conducted EMI in the 30–100 MHz band, easing compliance with CISPR 32 Class B limits without additional snubbing components.

Can ES3C-13 replace ES3B-13 in an existing design?

Yes-ES3C-13 (150 V V_RRM) can safely replace ES3B-13 (100 V V_RRM) where higher reverse voltage margin is needed. No layout or thermal changes are required since both share identical SMC package, pinout, and thermal characteristics; however, verify system peak reverse stress does not exceed 100 V before downgrade.
