Engineered for high-efficiency power conversion topologies, this 2-pin device delivers a repetitive peak reverse voltage rating of 100 V and an average rectified forward current of 1.0 A. It features an exceptionally fast reverse recovery time (trr) of 15 ns, making it well-suited for high-frequency switching applications where minimizing switching losses and reducing reverse recovery current spikes are critical for optimal thermal and electrical performance. Key electrical parameters include a maximum forward voltage drop of 920 mV at 1.0 A and a robust non-repetitive peak forward surge current handling capability of up to 30 A based on an 8.3 ms single half-sine-wave. The component operates across a wide junction temperature range of -50°C to +150°C, supported by a thermal resistance of 85°C/W from junction to ambient when mounted on standard FR-4 printed circuit board layouts. The SMA package incorporates a built-in strain relief structure and facilitates automated pick-and-place assembly, ensuring mechanical reliability in dense surface-mount electronics manufacturing. This ultrafast diode is typically deployed in high-frequency power supplies, DC-DC buck and boost converters, freewheeling diode circuits, and general-purpose rectification tasks in industrial and consumer electronics. Its low capacitance profile (7.0 pF at 4.0 V, 1 MHz) and rapid turn-off characteristics mitigate electromagnetic interference (EMI) and power dissipation in high-speed switching loops. The ES1B meets stringent environmental standards, adhering to lead-free construction criteria while providing dependable operational stability under continuous thermal stress up to its maximum rated limits. ## Specifications | Parameter | Value | |---|---| | Svhc | Lead (25-Jun-2025) | | No. Of Pins | 2 Pin | | Product Range | ES1B | | Qualification | - | | Diode Case Style | DO-214AC (SMA) | | Diode Configuration | Single | | Forward Voltage Max | 920mV | | Forward Surge Current | 30A | | Reverse Recovery Time | 15ns | | Average Forward Current | 1A | | Operating Temperature Max | 150°C | | Repetitive Peak Reverse Voltage | 100V | ## Datasheet 📄 [Download PDF](https://novapart.co/datasheet/farnell:2438215/) ## **Is Now Part of** **To learn more about ON Semiconductor, please visit our website at www.onsemi.com** ON Semiconductor and the ON Semiconductor logo are trademarks of Semiconductor Components Industries, LLC dba ON Semiconductor or its subsidiaries in the United States and/or other countries.
