Product details
Overview
ES3BB-13 from Diodes Incorporated is a 100V peak repetitive reverse voltage, 3.0A average rectified current, super-fast recovery (25 ns) surface-mount rectifier in SMB package with glass-passivated die and 0.9V forward voltage at 3.0A - used in high-efficiency AC/DC front-end and DC/DC flyback secondary-side rectification.
For engineers reviewing the ES3BB-13 datasheet, ES3BB-13 pinout, ES3BB-13 application, or ES3BB-13 equivalent, key selection criteria include reverse recovery time, thermal resistance (15°C/W), surge rating (100A), RoHS-compliant matte tin plating, and SMB footprint compatibility with automated SMT assembly.
Technical Context
This discrete power diode employs a planar epitaxial silicon structure with glass passivation for stable junction integrity under thermal cycling. Its 25 ns reverse recovery time enables operation in switching power supplies up to 500 kHz without excessive switching loss.
The device exhibits low forward voltage (0.9 V @ 3.0 A) and low junction-to-terminal thermal resistance (15°C/W), enabling high-current rectification on standard PCB copper pads (5.0 mm², 0.013 mm thick) without external heatsinking at ≤100°C terminal temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - maximum non-repetitive reverse voltage the diode blocks reliably in circuit |
| IO | 3.0 A - continuous average forward current sustainable at 100°C terminal temperature |
| trr | 25 ns - measured under IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A; enables high-frequency SMPS operation |
| VFM | 0.9 V @ 3.0 A - forward conduction loss directly impacts efficiency and thermal rise in rectifier stage |
| IFSM | 100 A - single half-sine surge rating (8.3 ms, JEDEC method); supports inrush and fault tolerance |
| RJT | 15 °C/W - junction-to-terminal thermal resistance defines minimum PCB copper area needed for thermal management |
| CT | 45 pF @ 1 MHz, 4 V - junction capacitance affects EMI and snubber design in high-dV/dt applications |
Pinout & Package
SMB (Surface-Mount Small Outline) package: molded plastic case (UL 94V-0), cathode marked by band or notch, solderable matte tin-plated terminals, moisture sensitivity level 1.

FAQ
What is the cathode marking convention for ES3BB-13?
The cathode is identified by a distinct band printed on the SMB package body, aligned with the cathode terminal. This band corresponds to the terminal opposite the anode in the standard SMB outline; orientation matches industry-standard SMB diode placement on PCB footprints.
Can ES3BB-13 replace ES3AB-13 in existing designs?
No - ES3BB-13 (SMB, 100 V) and ES3AB-13 (SMC, 50 V) differ in both package size and voltage rating. SMB and SMC are mechanically incompatible footprints, and VRRM differs by 50 V; substitution requires layout revision and derating analysis for reverse voltage margin.
Is ES3BB-13 suitable for synchronous rectification circuits?
No - ES3BB-13 is a passive super-fast rectifier, not a synchronous rectifier IC or MOSFET-based device. It lacks gate drive interface or control logic; it functions only as a unidirectional current path triggered by voltage polarity, not timing signals.
What is the maximum allowable PCB copper pad area for thermal performance?
The datasheet specifies thermal characterization using 5.0 mm² (0.013 mm thick) copper pads per terminal. Increasing pad area beyond this improves thermal resistance linearly; doubling pad area reduces RJT by ~20%, but no upper limit is defined - design must balance space, isolation, and creepage requirements.
