Product details
Overview
ES3JB from Taiwan Semiconductor is a 600 V, 3 A super fast recovery surface-mount rectifier in DO-214AA (SMB) package, with 1.11–1.30 V forward voltage at 1.5 A and 25°C, 35 ns reverse recovery time, and 34 pF junction capacitance - used in high-frequency switching power supplies and LED lighting converters.
For engineers reviewing the ES3JB datasheet, ES3JB pinout, ES3JB application, or ES3JB equivalent, key selection criteria include peak reverse voltage rating, forward voltage drop at operating current/temperature, thermal resistance (RθJL = 24°C/W), and moisture sensitivity level (MSL 1).
Technical Context
The ES3JB employs a glass-passivated silicon junction for stable performance under thermal cycling and high dv/dt stress. Its super fast recovery (trr ≤ 35 ns) enables efficient operation in 100–500 kHz SMPS topologies without significant switching loss penalties.
Designed for surface-mount assembly on standard PCBs with 10 mm × 10 mm copper pads, the device delivers RθJA = 84°C/W and RθJC = 26°C/W, supporting continuous 3 A conduction up to TJ = 150°C with appropriate board-level thermal management.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - maximum repetitive reverse blocking voltage; defines safe operating range in high-voltage DC-link or PFC stages |
| IF | 3 A - average forward current rating at TA = 75°C; supports continuous output in compact 30–60 W adapters |
| VF @ 1.5A, 25°C | 1.11–1.30 V - forward voltage range determines conduction loss and thermal load in primary-side rectification |
| trr | ≤35 ns - reverse recovery time enables use in high-frequency flyback and resonant LLC converters without excessive ringing |
| CJ @ 1 MHz, 4 V | 34 pF - low junction capacitance minimizes capacitive coupling and EMI generation in fast-switching nodes |
| RθJL | 24°C/W - junction-to-lead thermal resistance allows direct heat transfer to PCB copper, critical for thermal reliability |
| MSL Level | Level 1 (per J-STD-020) - no floor life limitation; suitable for standard reflow without baking preconditioning |
Pinout & Package
Package: DO-214AA (SMB), molded plastic case with matte tin-plated leads, polarity indicated by cathode band, weight ≈ 0.110 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side of AC input or transformer secondary; must handle 100 A surge (IFSM) |
| Cathode | Forward current exit / reverse voltage terminal | Connected to output rail or switching node; marked by visible band; withstands full 600 V reverse bias |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Enables stable leakage current (<10 µA @ 25°C) and long-term reliability under humidity and thermal stress |
| Super fast recovery (trr ≤ 35 ns) | Reduces switching losses and EMI in >200 kHz SMPS designs compared to standard fast rectifiers (≥75 ns) |
| DO-214AA (SMB) low-profile package | 0.9 mm max height supports ultra-thin adapter and LED driver PCBs while maintaining 3 A current capability |
| RoHS & halogen-free compliance | Meets IEC 61249-2-21 and EU RoHS Directive 2011/65/EU for environmentally constrained industrial and consumer applications |
Applications
| Switching Mode Power Supply (SMPS) | LED Lighting Converter |
|---|---|
Use Scenario: Secondary-side rectification in 30–60 W offline flyback converters with 100–500 kHz switching frequency. IC Role / Device Role / Timing Role: High-efficiency unidirectional current path converting high-frequency AC from transformer secondary to regulated DC output. Use Value: Low VF (1.24–1.45 V @ 3 A, 25°C) and fast trr minimize conduction + switching losses, improving efficiency by ≥0.8% over standard FR diodes. | Use Scenario: Constant-current output rectification in isolated LED drivers powering streetlights or commercial downlights. IC Role / Device Role / Timing Role: Output rectifier handling pulsed DC with high dv/dt; operates under ambient temperatures up to 85°C. Use Value: MSL Level 1 and 150°C TJMAX ensure robustness during reflow and field operation; low CJ (34 pF) suppresses high-frequency noise coupling into sensitive current-sense circuits. |
| AC-DC Adapter | DC-DC Converter |
Use Scenario: Compact wall-wart and USB-C PD adapters requiring high power density and low no-load loss. IC Role / Device Role / Timing Role: Primary-side or secondary-side rectifier depending on topology; handles 3 A average current with 100 A surge tolerance. Use Value: RθJL = 24°C/W enables direct thermal coupling to PCB ground plane, reducing need for heatsinks and lowering BOM cost. | Use Scenario: Isolated DC-DC modules in industrial PLCs and IoT gateways operating from 24 V or 48 V input rails. IC Role / Device Role / Timing Role: Synchronous or asynchronous rectifier in forward or half-bridge topologies; interfaces with PWM controller via low-inductance layout. Use Value: 600 V VRRM provides sufficient margin for 400 V DC-link transients, ensuring system-level safety and longevity. |
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 (STMicroelectronics) | Same DO-214AA package, 600 V VRRM, but higher VF (1.45 V @ 3 A) and slower trr (50 ns) | Suitable for lower-frequency (<150 kHz) SMPS where efficiency margin is less critical | Prefer ES3JB when optimizing for efficiency in high-frequency designs |
| SS36 (Vishay) | 60 V VRRM, not rated for 600 V systems; otherwise similar SMB footprint and 3 A rating | Only usable in low-voltage secondary-side or DC-DC outputs, not primary rectification | Select ES3JB for universal input or high-voltage DC-link applications requiring 600 V blocking |
Compared with STTH3L06S and SS36, the ES3JB delivers superior high-frequency efficiency due to its lower VF and faster trr, while uniquely supporting 600 V operation in the same SMB footprint - making it optimal for compact, universal-input power supplies.

FAQ
What is the maximum junction temperature rating for the ES3JB?
The ES3JB has a maximum junction temperature (TJMAX) of +150°C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet. This rating allows continuous 3 A operation in environments up to 75°C ambient when mounted on a 10 mm × 10 mm Cu pad, provided thermal design accounts for RθJA = 84°C/W. Derating curves confirm usable current down to 0 A at 150°C ambient.
Does the ES3JB have a specified reverse recovery time, and how is it measured?
Yes, the ES3JB has a reverse recovery time (trr) of ≤35 ns, measured under conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A, per the official Taiwan Semiconductor datasheet. This value is confirmed across all production lots and reflects performance at 25°C ambient; trr increases slightly at elevated junction temperatures but remains below 50 ns up to 125°C.
Is the ES3JB lead-free and RoHS compliant?
Yes, the ES3JB is fully RoHS compliant and halogen-free per IEC 61249-2-21. Its matte tin-plated leads meet J-STD-002 solderability requirements, and the molding compound complies with UL 94V-0 flammability rating. The device carries MSL Level 1 classification, confirming no moisture sensitivity concerns during standard SMT reflow.
What is the forward voltage range of the ES3JB at 3.0 A and 25°C?
The ES3JB exhibits a forward voltage (VF) range of 1.24–1.45 V at IF = 3.0 A and TJ = 25°C, as specified in the Electrical Specifications table of the Taiwan Semiconductor datasheet. This range reflects unit-to-unit process variation and ensures guaranteed performance within these bounds across all shipped units.
Can the ES3JB be used as a direct replacement for ES3GB or ES3HB in existing designs?
Yes, the ES3JB shares identical DO-214AA (SMB) package dimensions, pinout, and thermal characteristics with ES3GB and ES3HB, differing only in VRRM (600 V vs. 400 V and 500 V). When substituting in a design originally using ES3GB or ES3HB, verify that the 600 V rating provides adequate margin for your circuit's peak reverse voltage - no PCB or layout changes are required.
