Product details

Overview

ES3B-13 from Diodes Incorporated is a 3.0A surface-mount super-fast rectifier diode in SMB package, rated for 100V peak repetitive reverse voltage (V_RRM), with 25ns reverse recovery time (t_rr) and 0.9V forward voltage at 3.0A, designed for high-efficiency AC/DC front-end rectification in compact power supplies.

For engineers reviewing the ES3B-13 datasheet, ES3B-13 pinout, ES3B-13 application, or ES3B-13 equivalent, key selection criteria include fast switching performance under 60Hz/rectified line conditions, thermal resistance (R_JT = 15°C/W), surge capability (I_FSM = 100A), RoHS-compliant lead-free finish, and SMB footprint compatibility with automated SMT assembly.

Technical Context

This super-fast rectifier employs glass-passivated silicon die optimized for low forward conduction loss and rapid minority-carrier recombination. Its 25ns t_rr enables operation in high-frequency switching converters up to ~100kHz without excessive switching loss or ringing.

Rated for 3.0A average rectified output current at T_T = 100°C with derating above that temperature, it supports continuous conduction mode (CCM) operation when mounted on 5.0 mm² copper pads. Reverse leakage remains ≤500 µA at 125°C and rated V_R.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	100 V - Maximum non-repetitive reverse voltage before breakdown; defines safe operating range in bridge or single-diode rectifier configurations.
I_O	3.0 A - Average forward current at terminal temperature of 100°C; determines continuous power handling with PCB copper heatsinking.
t_rr	25 ns - Measured with I_F = 0.5A, I_R = 1.0A, I_rr = 0.25A; enables reduced switching loss vs. standard fast rectifiers in SMPS.
V_FM	0.9 V @ 3.0A - Forward voltage drop at rated DC current; directly impacts conduction loss and thermal design in high-current paths.
I_FSM	100 A - Non-repetitive surge rating (8.3ms half-sine); supports inrush current tolerance during cold-start of offline power supplies.
R_JT	15 °C/W - Junction-to-terminal thermal resistance; used with PCB pad area to calculate junction temperature rise under load.

Pinout & Package

ES3B-13 uses the SMB (DO-214AA) surface-mount package: molded plastic case, UL 94V-0 rated, cathode indicated by band or notch, mountable in any orientation. Terminal plating is matte tin (lead-free/RoHS compliant).

Pin/Terminal	Circuit Role	Design Meaning
Anode	Forward current entry point	Connected to AC input or transformer secondary side; must withstand full surge current and reverse voltage stress.
Cathode	Forward current exit / reverse blocking node	Connected to output capacitor or DC bus; polarity marking ensures correct placement in bridge or single-diode topology.

Key Features

Feature	Design Value
Glass-passivated die construction	Enhances reliability and moisture resistance versus epoxy-passivated alternatives; critical for long-term stability in humid environments.
Super-fast 25ns recovery time	Reduces reverse recovery charge (Q_rr) and associated switching losses in high-frequency rectification stages.
Low 0.9V forward drop at 3.0A	Lowers conduction loss by ~15% compared to standard fast rectifiers (e.g., 1.05V typical), improving efficiency in 5–24V output supplies.
100A surge rating (JEDEC method)	Supports robust startup behavior in offline SMPS without requiring oversized input fusing or NTC thermistors.

Applications

AC/DC Adapter Input Stage

USB-C PD Power Supply Output Rectification

Use Scenario: 100–240V AC input rectification feeding a 65W flyback converter with active clamp or QR control.

IC Role / Device Role / Timing Role: Primary-side super-fast rectifier in voltage-doubler or bridge configuration; handles 50/60Hz line frequency with minimal conduction loss.

Use Value: 0.9V V_FM reduces heat generation on primary-side PCB, enabling smaller heatsink area and higher power density.

Use Scenario: Secondary-side synchronous rectification replacement in 20–100W USB-C PD adapters using discrete diode-based designs.

IC Role / Device Role / Timing Role: Discrete ultrafast rectifier replacing Schottky diodes where higher V_RRM and lower cost are prioritized over ultra-low V_F.

Use Value: 100V V_RRM safely accommodates reflected voltage spikes in QR flyback topologies without snubber oversizing.

Industrial PLC Power Input Module

LED Driver Bulk Rectification

Use Scenario: 24V/48V DC input conditioning stage accepting wide-range industrial AC or DC inputs with transient protection.

IC Role / Device Role / Timing Role: Input rectifier in dual-input (AC+DC) power module; operates continuously at elevated ambient temperatures up to 70°C.

Use Value: R_JT = 15°C/W and 150°C max T_j rating allow reliable operation without forced air cooling in sealed enclosures.

Use Scenario: Bulk rectification for constant-current LED drivers powering streetlights or high-bay fixtures with universal AC input.

IC Role / Device Role / Timing Role: High-current rectifier in bridge configuration feeding bulk capacitor; subjected to repeated 100A surge events during hot-plug cycles.

Use Value: 100A I_FSM rating eliminates need for external surge limiting, simplifying BOM and reducing board space.

Equivalent & Alternatives

The following parts are listed as comparable options for similar super-fast rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH3L06S	V_RRM = 60V, t_rr = 35ns, V_F = 0.95V @ 3A, SMB package	Limited to ≤60V systems; slower recovery increases switching loss above 50kHz	Select only if system V_R < 42V and cost sensitivity outweighs efficiency needs.
MBR3100F	V_RRM = 100V, t_rr = 35ns, V_F = 0.85V @ 3A, SMB package	Schottky construction lowers V_F but limits max T_j to 125°C and increases leakage at high temperature	Prefer for low-V_F priority in <85°C ambient; avoid in high-temp industrial environments.

Compared with STTH3L06S and MBR3100F, ES3B-13 delivers optimal balance of 100V rating, 25ns speed, and 150°C operation-making it uniquely suited for thermally constrained, universal-input industrial power supplies where reliability trumps marginal V_F reduction.

FAQ

What is the maximum junction temperature for ES3B-13?

The absolute maximum junction temperature (T_j) for ES3B-13 is +150°C, as specified in the DS14003 datasheet. This rating allows operation in sealed industrial enclosures with ambient temperatures up to 70°C when mounted on 5.0 mm² copper pads, provided thermal design accounts for R_JT = 15°C/W and power dissipation.

Is ES3B-13 compatible with lead-free reflow soldering processes?

Yes, ES3B-13 features a matte tin lead-free terminal finish compliant with RoHS Directive 2011/65/EU and qualified for standard Pb-free reflow profiles (J-STD-020D). The device withstands peak temperatures up to 260°C for 30 seconds, matching IPC-A-610 Class 2/3 requirements.

How does ES3B-13 differ from ES3A-13 in practical design?

ES3B-13 has a 100V V_RRM rating versus 50V for ES3A-13, making it suitable for universal-input (85–265V AC) power supplies where reflected voltages exceed 70V. Both share identical SMB package, 25ns t_rr, and 3.0A I_O, so layout and thermal design remain unchanged across the series.

Can ES3B-13 replace a Schottky diode in a 24V output rectifier?

Yes, but only if reverse voltage stress stays below 100V and efficiency trade-offs are acceptable. While ES3B-13 offers superior thermal rating (150°C vs. typically 125°C for Schottkys) and lower cost, its 0.9V V_F is higher than typical Schottky V_F (~0.5V), increasing conduction loss by ~35% at 3A-requiring careful thermal validation.
