Diodes Incorporated ES3A-13

Overview

ES3A-13 from Diodes Incorporated is a 3.0A surface-mount super-fast rectifier diode in SMC package, rated for 50V peak repetitive reverse voltage (V_RRM), with 0.9V forward voltage at 3.0A, 25ns reverse recovery time, and 100A non-repetitive surge capability - used in high-frequency AC/DC converters and switch-mode power supplies.

For engineers reviewing the ES3A-13 datasheet, ES3A-13 pinout, ES3A-13 application, or ES3A-13 equivalent, key selection criteria include V_RRM, I_O, t_rr, V_F, and thermal resistance to ensure efficiency and reliability in compact, high-switching-frequency power stages.

Technical Context

This super-fast rectifier employs glass-passivated die construction to achieve low leakage and stable high-temperature operation up to +150°C junction temperature. Its 25ns reverse recovery time (measured at I_F = 0.5A, I_R = 1.0A, I_RR = 0.25A) enables use in 100–500 kHz SMPS topologies without excessive switching loss.

The device features a cathode band polarity marker and is qualified for automated SMT assembly. Thermal resistance from junction to terminal is 15°C/W under standard PCB mounting (5.0 mm² × 0.013 mm Cu pad), supporting continuous 3.0A output at T_T = 100°C.

Key Specifications

Pinout & Package

ES3A-13 uses an SMC (DO-214AB) surface-mount package with two terminals: anode and cathode. Polarity is marked by a cathode band on the body. Mounting orientation is unrestricted.

FAQ

What is the maximum junction temperature for ES3A-13?

The absolute maximum junction temperature is +150°C, and the device is characterized for continuous operation up to this limit when terminal temperature is maintained at ≤100°C per the derating curve. Thermal design must account for R_θJT = 15°C/W and PCB copper area per datasheet Note 1.

Is ES3A-13 pin-compatible with ES3AB-13?

No - ES3A-13 uses the larger SMC (DO-214AB) package, while ES3AB-13 uses the smaller SMB (DO-214AA) package. Though electrically identical in ratings, their footprints, thermal mass, and current-handling capacity differ; PCB layout and thermal design must be verified separately for each.

Does ES3A-13 require a heatsink in standard applications?

No external heatsink is required. With R_θJT = 15°C/W and proper 5.0 mm² copper pad layout, ES3A-13 sustains 3.0A average current at T_T = 100°C. Heatsinking becomes necessary only if ambient exceeds 70°C or PCB copper area is reduced below specification.

What is the meaning of the "-13" suffix in ES3A-13?

The "-13" suffix denotes tape-and-reel packaging: 3,000 units per reel, compliant with EIA-481-D standards. It does not indicate date code, revision, or electrical variant - all ES3A-13 units share identical electrical and thermal specifications per DS14003 Rev. 9.
