Product details
Overview
ES3CB-13 from Diodes Incorporated is a 150 V, 3.0 A surface-mount super-fast rectifier in SMB package with 25 ns reverse recovery time, 0.9 V forward voltage at 3.0 A, and 100 A non-repetitive surge rating - deployed in high-frequency AC/DC adapters and switch-mode power supplies.
For engineers reviewing the ES3CB-13 datasheet, ES3CB-13 pinout, ES3CB-13 application, or ES3CB-13 equivalent, key selection criteria include peak repetitive reverse voltage (150 V), thermal resistance (15 °C/W), low forward voltage drop, fast recovery for efficiency-critical flyback and PFC stages, and RoHS-compliant matte tin plating.
Technical Context
This discrete silicon rectifier uses glass-passivated die construction to achieve stable junction performance across -65°C to +150°C operating range. Its 25 ns trr enables operation in 100–500 kHz switching topologies without excessive switching loss.
The device supports automated SMT assembly with SMB footprint (4.06–4.57 mm × 1.96–2.21 mm) and solderable terminals compliant with MIL-STD-202 Method 208. Polarity is marked by cathode band; mounting orientation is unrestricted.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 150 V - Maximum peak repetitive reverse voltage before avalanche conduction begins; sets safe operating margin in 115/230 VAC input rectification. |
| IO @ TT=100°C | 3.0 A - Average rectified output current with terminal temperature held at 100°C using 5.0 mm² copper pad heatsink. |
| VFM @ IF=3.0A | 0.9 V - Forward voltage drop at rated DC load; directly determines conduction loss (2.7 W at full load). |
| trr | 25 ns - Reverse recovery time measured at IF=0.5A, IR=1.0A, Irr=0.25A; enables high-frequency operation with minimal tail current loss. |
| IFSM | 100 A - Non-repetitive surge rating per JEDEC 8.3 ms half-sine wave; withstands inrush during cold-start of SMPS. |
| RθJT | 15 °C/W - Junction-to-terminal thermal resistance; defines temperature rise above PCB pad under steady-state power dissipation. |
Pinout & Package
SMB (Surface-Mount Small Outline) package: 2-terminal, single-diode configuration with cathode band marking. Dimensions: 4.06–4.57 mm (L) × 1.96–2.21 mm (W) × 2.00–2.62 mm (H). Molded plastic case, UL 94V-0 rated.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Input current entry point | Connected to AC source or transformer secondary; must handle full surge current and RMS ripple. |
| Cathode | Output current exit point | Feeds bulk capacitor or downstream converter; polarity mark ensures correct PCB layout and avoids reverse bias failure. |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated die | Ensures stable leakage current and long-term reliability under humidity and thermal cycling stress. |
| Super-fast 25 ns recovery | Reduces reverse recovery charge (Qrr) and associated switching losses in high-frequency converters. |
| Low 0.9 V VF at 3.0 A | Lowers conduction loss versus standard FR/FRED diodes, improving efficiency in compact 3–5 W adapters. |
| RoHS-compliant matte tin plating | Enables lead-free reflow soldering without whisker risk or intermetallic degradation. |
Applications
| AC/DC Adapter Rectification | Active PFC Output Stage |
|---|---|
Use Scenario: 115/230 VAC input rectification in compact wall-wart adapters delivering 5–12 V/2–3 A. IC Role / Device Role / Timing Role: Primary-side unidirectional current path converting AC to pulsating DC prior to bulk capacitance. Use Value: 25 ns trr minimizes switching loss at 100–250 kHz operation; 0.9 V VF reduces heat generation in space-constrained enclosures. | Use Scenario: Output rectification in boost-type active PFC circuits operating at 65–130 kHz. IC Role / Device Role / Timing Role: Freewheeling path for inductor current during MOSFET off-time; handles high di/dt and voltage reversal. Use Value: 150 V VRRM provides 2× safety margin over 385 VDC bus; 100 A IFSM absorbs PFC startup surges. |
| Flyback Converter Secondary | Industrial Control Power Supply |
Use Scenario: Secondary-side rectification in isolated 12–24 V/1–3 A flyback supplies for PLC I/O modules. IC Role / Device Role / Timing Role: High-efficiency synchronous or quasi-resonant rectifier replacement where Schottky cost or leakage is prohibitive. Use Value: 15 °C/W RθJT allows direct thermal coupling to PCB copper; 3.0 A IO sustains continuous load without derating at 70°C ambient. | Use Scenario: Auxiliary 5/12 V bias supply in motor drives and industrial HMIs requiring extended temperature operation. IC Role / Device Role / Timing Role: Input-stage bridge leg or standalone rectifier handling line transients and wide ambient (-40°C to +85°C). Use Value: -65°C to +150°C Tj range ensures functionality during thermal shock; glass passivation prevents moisture-induced parameter drift. |
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 | 600 V VRRM, 3.0 A IO, 35 ns trr, TO-277 package | Higher voltage rating suits 400 VDC bus designs; larger thermal mass but requires different footprint. | Select when >200 V reverse blocking is required and board space permits TO-277 mounting. |
| SB3150-TB | 150 V VRRM, 3.0 A IO, 30 ns trr, SMB package, 0.85 V VF | Near-identical specs but lower VF improves conduction efficiency; slightly slower recovery increases switching loss at >300 kHz. | Prefer for ultra-low-loss 5 V/3 A outputs where <0.1 V VF reduction justifies marginal trr trade-off. |
Compared with ES3CB-13, STTH3L06S offers higher voltage headroom at the cost of larger size and slower recovery, while SB3150-TB matches SMB footprint and voltage rating but trades 5 ns of speed for 50 mV lower VF - making it optimal for fixed-frequency, low-VF priority designs.

FAQ
What is the maximum junction temperature for ES3CB-13?
The absolute maximum junction temperature is +150°C, with storage temperature matching this range. Operation at full 3.0 A load requires thermal management via ≥5.0 mm² copper pad to maintain TJ ≤ 150°C at 100°C terminal temperature, per datasheet note 1.
Does ES3CB-13 support lead-free reflow soldering?
Yes - ES3CB-13 features matte tin lead-free plating compliant with RoHS Directive 2002/95/EC (Annex exemptions applied), qualified for standard Pb-free reflow profiles up to 260°C peak, per J-STD-020C Level 1 moisture sensitivity.
How does the 25 ns reverse recovery time impact EMI in SMPS designs?
A 25 ns trr limits reverse recovery di/dt, reducing high-frequency ringing on the switching node. This lowers radiated EMI in 100–500 kHz flyback and PFC stages, easing compliance with CISPR-22 Class B limits without additional snubbing.
Can ES3CB-13 replace a standard FR107 in an existing design?
Yes - with identical SMB footprint and 150 V rating, ES3CB-13 substitutes FR107 while improving trr (25 ns vs. 500 ns) and VF (0.9 V vs. 1.3 V). Verify layout clearance for faster edge rates and confirm thermal margin due to higher frequency operation.
