Vishay 50 V 1 A General Purpose Silicon Junction Diode Surface Mount DO-214AC ES1A-E3/5AT

Vishay ES1A-E3/5AT is a high-quality general purpose silicon junction diode designed for surface mount technology in a compact DO-214AC (SMA) package. It supports continuous forward currents up to 1 A and peak reverse voltages of 50 V, making it suitable for a broad range of industrial and commercial electronic applications.

This diode features a glass passivated pellet chip junction delivering enhanced reliability and stable performance. Its ultrafast recovery time of 25 ns and low forward voltage of 920 mV ensure efficient operation with minimal power loss, critical in high-frequency switching environments.

The device supports a peak non-repetitive surge current of 30 A, allowing it to endure transient conditions without damage. It operates effectively in a temperature range from -55°C to 150°C, allowing deployment in demanding environments including automotive applications where AEC-Q101 qualification applies.

Constructed with matte tin plated leads solderable per J-STD-002 and tested to JESD 22-B102 standards, the diode ensures excellent solderability and compatibility with automated assembly lines. The case material complies with UL 94 V-0 flammability ratings, supporting product safety standards.

Common use cases include high frequency rectification and freewheeling in switching mode power supplies, converters, and motor drive inverters across sectors such as consumer electronics, computer hardware, automotive systems, and telecommunications equipment.

The diode comes supplied in a low profile SMA case suitable for automated placement. Its robust electrical characteristics enable reliable performance in power management circuits. Its automotive-grade variant supports rigorous industry demands.

The color band marking ensures correct polarity installation. RoHS-compliant with several commercial and automotive-grade options available.
