BYM12-50HE3/96

Overview

The BYM12-50HE3/96 is a surface-mount glass-passivated ultrafast rectifier manufactured by Vishay General Semiconductor. It utilizes the Superectifier structure within the GL41 (DO-213AB) package to ensure high reliability and cavity-free junction integrity. The device supports a maximum average forward rectified current of 1.0 A at 75 °C and withstands a peak forward surge current of 30 A. Key electrical specifications include a maximum repetitive peak reverse voltage of 50 V, a maximum instantaneous forward voltage of 1.0 V, and an ultrafast reverse recovery time of 50 ns. The component operates across a wide temperature range from -65 °C to +175 °C.

Feature Summary

• Superectifier structure provides high reliability with a cavity-free glass-passivated junction

• Ideal for automated placement processes in surface-mount applications

Applications

• High frequency rectification in switching mode converters
• Freewheeling applications in inverters
• Consumer electronics power supplies
• Computer equipment power systems
• Automotive electronic circuits
• Telecommunication infrastructure

Procurement Notes

Verify the specific part number against official Vishay documentation to confirm compliance with RoHS directives and material categorization standards. Ensure that the EGL41A designation matches the required 50 V rating. Confirm packaging details such as tape and reel dimensions before procurement. Check for any regional technical support requirements or specific environmental standard certifications like MIL-S-19500 if applicable to your design constraints.

Selection Notes

Select this component when designing circuits requiring fast switching speeds and low reverse leakage currents in a compact surface-mount form factor. The 50 V rating suits low-voltage DC-DC conversion stages. Consider the thermal resistance characteristics and derating curves for high ambient temperature environments. Verify compatibility with automated assembly lines due to the MELF-style GL41 package geometry and polarity band markings.

Part Context

This device belongs to the BYM12 series of ultrafast rectifiers, which are designed for general-purpose high-frequency applications. The series includes variants with different voltage ratings up to 400 V, all sharing similar mechanical and electrical characteristics. The GL41 package offers a robust solution for space-constrained designs while maintaining high surge capability and thermal performance compared to standard rectifiers.

Replacement Considerations

Direct substitutes within the same family include BYM12-100HE3/96, BYM12-150HE3/96, BYM12-200HE3/96, BYM12-300HE3/96, and BYM12-400HE3/96. These parts share identical package dimensions and current ratings but differ in their maximum repetitive peak reverse voltage ratings. Ensure the replacement voltage rating meets or exceeds the circuit requirements.
