Product details

Overview

ES3BB from Taiwan Semiconductor is a 3A, 100V super fast surface-mount rectifier in DO-214AA (SMB) package, featuring 35ns reverse recovery time, 0.92V forward voltage at 1.5A/25°C, and 100A surge current capability - deployed in high-frequency switching power supplies and LED lighting converters.

For engineers reviewing the ES3BB datasheet, ES3BB pinout, ES3BB application, or ES3BB equivalent, key selection criteria include V_RRM = 100 V, I_F = 3 A, t_rr = 35 ns, thermal resistance R_θJL = 24 °C/W, and SMB package compatibility with automated SMT assembly.

Technical Context

The ES3BB operates as a single-die, unidirectional silicon rectifier optimized for high-efficiency DC/DC conversion in compact power stages. Its glass-passivated junction ensures stable performance under thermal cycling, while the low-profile SMB package supports dense PCB layouts.

With a maximum junction temperature of 150°C and moisture sensitivity level 1 (per J-STD-020), the ES3BB sustains reliable operation in thermally constrained environments such as enclosed adapters and LED drivers without derating below 3A continuous forward current at 75°C ambient.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	100 V - Maximum repetitive reverse voltage before breakdown; defines safe operating range in 12–48 V output SMPS secondary-side rectification.
I_F	3 A - Continuous average forward current; supports 36 W output at 12 V with typical conduction losses under 0.9 W.
t_rr	35 ns - Reverse recovery time; enables >300 kHz switching frequencies with minimal switching loss and EMI generation.
V_F @ 1.5A, 25°C	0.92 V - Forward voltage drop; contributes to ~1.4 W conduction loss at full load, requiring ≤24°C/W heatsinking for 150°C junction limit.
R_θJL	24 °C/W - Junction-to-lead thermal resistance; allows direct thermal path to PCB copper, enabling 3 A operation on 10 mm × 10 mm Cu pad without forced air.
I_FSM	100 A - Non-repetitive peak surge current (8.3 ms half-sine); withstands inrush events in offline AC/DC front-ends and hot-plug circuits.

Pinout & Package

Package: DO-214AA (SMB), surface-mount, low-profile plastic case with matte tin-plated leads; polarity indicated by cathode band; weight ≈ 0.110 g.

Pin/Terminal	Circuit Role	Design Meaning
Anode (A)	Forward current entry point	Connected to transformer secondary or switch node; must handle 3 A RMS and 100 A surge without bond wire fusing.
Cathode (K)	Forward current exit / reverse blocking terminal	Connected to output capacitor; cathode band marks this terminal for correct orientation during automated placement.

Key Features

Feature	Design Value
Glass passivated junction	Enables stable leakage current (<10 µA at 25°C) and long-term reliability under humidity and thermal stress per JESD22-A101.
Super fast recovery (35 ns)	Reduces switching loss and diode-induced ringing in high-frequency flyback and LLC resonant converters.
Moisture sensitivity level 1	Eliminates bake requirement prior to reflow; compatible with standard J-STD-020-compliant SMT lines without dry-pack handling.
Halogen-free & RoHS compliant	Meets IEC 61249-2-21 and EU Directive 2011/65/EU; suitable for consumer, industrial, and medical-adjacent applications.

Applications

AC/DC Adapters	LED Lighting Drivers
Use Scenario: Secondary-side rectification in 12–24 V, 30–60 W wall adapters with <300 kHz PWM control. IC Role / Device Role / Timing Role: Unidirectional current valve converting high-frequency transformer output to regulated DC; replaces slower FR107/UF4007 in space-constrained designs. Use Value: 35 ns t_rr reduces reverse recovery charge Q_rr, cutting switching loss by ~40% vs. standard fast rectifiers at 250 kHz.	Use Scenario: Constant-current rectification in isolated LED drivers for commercial downlights and streetlight modules. IC Role / Device Role / Timing Role: Output rectifier in quasi-resonant flyback topology; handles 3 A continuous current with minimal thermal rise on 2-layer PCBs. Use Value: R_θJL = 24 °C/W enables 3 A operation with ≤45°C junction rise above ambient on 10 mm × 10 mm Cu pad - no heatsink required.
Industrial SMPS	DC/DC Converters
Use Scenario: Input rectification in 48 V telecom power modules with wide ambient (-40°C to +85°C) and high reliability requirements. IC Role / Device Role / Timing Role: Primary-side or auxiliary rail rectifier; selected for 100 V V_RRM margin over 48 V nominal input with transient tolerance. Use Value: 150°C max junction temperature and -55°C to +150°C storage range support extended lifetime in sealed enclosures without active cooling.	Use Scenario: Synchronous rectifier replacement in isolated 5–12 V output buck-derived converters for FPGA and ASIC power rails. IC Role / Device Role / Timing Role: Freewheeling diode in non-synchronous buck-boost or SEPIC topologies where gate drive complexity is avoided. Use Value: Low V_F (0.92 V @ 1.5 A) minimizes conduction loss versus Schottky alternatives with higher leakage at elevated temperatures.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
Vishay VS-3EWH01-M3/5AT	V_RRM = 100 V, I_F = 3 A, t_rr = 35 ns, same SMB package; VF = 0.95 V @ 1.5 A - 30 mV higher than ES3BB.	Identical use in SMPS and adapters; slightly higher conduction loss may require minor thermal margin adjustment.	Preferred where Vishay's qualification history in automotive-grade power supplies is required.
ON Semiconductor MUR310RLG	V_RRM = 100 V, I_F = 3 A, t_rr = 50 ns - 15 ns slower; VF = 0.87 V @ 1.5 A - 50 mV lower than ES3BB.	Better conduction efficiency but higher switching loss at >200 kHz; less suitable for high-frequency LED drivers.	Select when thermal budget is tight but switching frequency remains ≤150 kHz.

Compared with VS-3EWH01-M3/5AT and MUR310RLG, the ES3BB delivers optimal balance of low V_F and ultra-fast t_rr in SMB format - making it ideal for compact, high-frequency, cost-sensitive power supplies where both conduction and switching losses must be minimized simultaneously.

FAQ

What is the maximum junction temperature rating for ES3BB?

The ES3BB has a maximum junction temperature (T_J) rating of +150°C, verified per absolute maximum ratings table in the official TSC datasheet Version C2102. This allows sustained 3 A operation at ambient temperatures up to 75°C on a standard 10 mm × 10 mm copper pad, provided thermal resistance R_θJA = 84 °C/W is maintained. Derating begins above 75°C ambient per the forward current derating curve.

Does ES3BB have a halogen-free and RoHS-compliant construction?

Yes, the ES3BB is halogen-free per IEC 61249-2-21 and RoHS compliant per EU Directive 2011/65/EU, as confirmed in the "Features" section of the TSC ES3AB–ES3JB datasheet (Version C2102). The molding compound meets UL 94V-0 flammability rating, and terminals are matte tin plated per J-STD-002 solderability standards.

What is the reverse recovery time (t_rr) of ES3BB and under what test conditions is it specified?

The ES3BB reverse recovery time is 35 ns, measured under conditions of I_F = 0.5 A, I_R = 1.0 A, I_RR = 0.25 A, per the Electrical Specifications table in the TSC datasheet. This value applies across the full operating temperature range and confirms suitability for switching frequencies up to 500 kHz with minimal dynamic loss.

Is ES3BB pin-compatible with other devices in the ES3x family?

Yes, all ES3x devices including ES3BB share identical DO-214AA (SMB) package dimensions, pinout (anode/cathode), polarity marking (cathode band), and thermal pad layout. Voltage ratings differ (e.g., ES3AB = 50 V, ES3CB = 150 V), but mechanical and soldering compatibility is fully maintained across the series.

What is the forward voltage drop of ES3BB at 3.0 A and 25°C?

The forward voltage drop (V_F) of ES3BB is 1.00 V at I_F = 3.0 A and T_J = 25°C, as specified in the Electrical Specifications table (page 2 of TSC datasheet Version C2102). At 125°C junction temperature, V_F drops to 0.84 V due to negative temperature coefficient of silicon PN junctions.
