Product details
Overview
ES3JB-A from Taiwan Semiconductor is a 3A, 600V super fast surface-mount rectifier in DO-214AA (SMB) package, featuring 1.48V forward voltage at 3A/25°C, 35ns reverse recovery time, and 24pF junction capacitance. It serves as a freewheeling or output rectifier in high-frequency switching power supplies.
For engineers reviewing the ES3JB-A datasheet, ES3JB-A pinout, ES3JB-A application, or ES3JB-A equivalent, key selection criteria include peak reverse voltage rating, thermal resistance (RθJL = 20°C/W), surge current capability (IFSM = 80A), and low leakage (<5µA @ 25°C).
Technical Context
The ES3JB-A employs a single-die, glass-passivated silicon junction optimized for high-voltage, high-speed switching. Its 600V VRRM and 35ns trr enable use in 100–500kHz SMPS topologies where fast recovery minimizes switching losses.
Thermal design is supported by RθJL = 20°C/W and RθJA = 78°C/W on a 10mm × 10mm Cu pad, with maximum junction temperature rated at +150°C and moisture sensitivity level 1 per J-STD-020.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - supports DC bus voltages up to 424V RMS in bridge configurations |
| IF | 3 A continuous - suitable for medium-power output stages without forced cooling |
| trr | 35 ns - reduces turn-off loss and EMI in high-frequency converters |
| VF @ 3A/25°C | 1.48 V - defines conduction loss at full load; impacts efficiency and thermal rise |
| CJ | 24 pF - limits capacitive coupling and ringing in high-dv/dt environments |
| IFSM | 80 A (8.3ms) - withstands startup surges and transient overloads |
| RθJL | 20 °C/W - enables direct PCB heat transfer to copper pour for thermal management |

Applications
| DC–DC Converter | Switching Inverter |
|---|---|
Use Scenario: Secondary-side synchronous rectification in isolated flyback or forward converters. IC Role / Device Role / Timing Role: Output rectifier handling 3A continuous current at 600V blocking.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-ES3JBHM3/5B | Identical VRRM (600V), IF (3A), and DO-214AA package; trr = 35ns, VF = 1.5V @ 3A/25°C | Same freewheeling and output rectification roles; qualified for automotive AEC-Q101 | Preferred where automotive qualification or extended temperature validation is required |
| ON Semiconductor MUR360 | 600V VRRM, 3A IF, but TO-220AC package; trr = 50ns, VF = 1.7V @ 3A/25°C | Requires through-hole mounting and larger board area; higher VF increases conduction loss | Consider only when SMB footprint is unavailable and thermal mass of TO-220 is advantageous |
Compared with VS-ES3JBHM3/5B, ES3JB-A offers identical electrical specs but lacks AEC-Q101 qualification; versus MUR360, ES3JB-A provides superior speed, lower forward drop, and surface-mount compatibility-critical for space-constrained, high-frequency designs.

FAQ
What is the maximum junction temperature rating for ES3JB-A?
The ES3JB-A has a maximum junction temperature (TJ) rating of +150°C, verified per absolute maximum ratings table. This allows reliable operation in enclosed industrial power supplies where ambient temperatures reach 85°C and thermal resistance to PCB is managed via 10mm × 10mm copper pads. The ES3JB-A must not exceed this limit during steady-state or transient conditions.
Does ES3JB-A have a specified reverse recovery time, and how is it measured?
Yes, ES3JB-A has a reverse recovery time (trr) of 35 ns, measured under conditions of IF = 0.5A, IR = 1.0A, and Irr = 0.25A. This value is confirmed in the Electrical Specifications table and reflects performance at room temperature. The ES3JB-A's 35 ns trr is critical for minimizing switching loss in 200–500 kHz SMPS designs.
Is ES3JB-A compatible with lead-free reflow soldering processes?
Yes, ES3JB-A features matte tin-plated leads compliant with J-STD-002 for solderability and is rated for moisture sensitivity level 1 per J-STD-020. No pre-bake is required before reflow. The ES3JB-A supports standard Pb-free reflow profiles (peak ≤260°C) and maintains mechanical integrity and electrical performance post-assembly.
What is the marking code printed on the ES3JB-A device body?
The ES3JB-A is marked with "ES3JB" on its case, as specified in the Absolute Maximum Ratings table. This marking distinguishes it from lower-voltage variants (e.g., ES3DB-A = "ES3DB", ES3GB-A = "ES3GB"). The ES3JB-A marking ensures visual identification during inspection and avoids substitution errors in high-voltage designs.
How does the junction capacitance of ES3JB-A compare to other parts in the ES3x-A family?
ES3JB-A has a typical junction capacitance (CJ) of 24 pF at 1 MHz and 4.0 V reverse bias-lower than ES3GB-A (37 pF) and ES3DB-A (57 pF). This reduction correlates with higher VRRM and thinner depletion layers. The ES3JB-A's 24 pF value helps suppress high-frequency ringing in fast-switching topologies, making it preferred for >300 kHz applications.
