BYM11-400-E3/96

Overview

The BYM11-400-E3/96 is a surface-mount glass passivated junction fast switching rectifier manufactured by Vishay General Semiconductor. It utilizes the Superectifier structure and is housed in a GL41 (DO-213AB) package. The device features a maximum repetitive peak reverse voltage of 400 V, a maximum average forward rectified current of 1.0 A, and a peak forward surge current capability of 30 A. Electrical characteristics include a maximum instantaneous forward voltage of 1.3 V at 1.0 A, a maximum DC reverse current of 5.0 µA at rated blocking voltage, and a typical junction capacitance of 15 pF. The component supports an operating junction temperature range from -65 °C to +175 °C.

Feature Summary

• Superectifier structure designed for high reliability under demanding conditions
• Fast switching performance optimized for high efficiency applications
• Low leakage current characteristics across operating temperatures
• High forward surge current capability for robust transient handling

Applications

• Fast switching rectification in power supply circuits
• Inverter and converter topologies
• Freewheeling diode implementation in consumer electronics
• Automotive electronic systems
• Telecommunication equipment

Procurement Notes

Verify the specific ordering code against the manufacturer's official documentation to ensure correct voltage rating and packaging configuration. Confirm RoHS compliance status and material categorization details prior to integration. Validate that the GL41 package dimensions align with the target PCB footprint and automated placement requirements. Cross-reference thermal resistance parameters with system cooling capabilities.

Selection Notes

Select this component when a single-diode fast recovery rectifier is required in a compact surface-mount form factor. The 400 V reverse voltage rating suits medium-voltage AC-DC conversion stages. Ensure the application demands a maximum average forward current not exceeding 1.0 A. Consider the 175 °C junction temperature limit for high-thermal environments. Verify that the 150 ns reverse recovery time meets the switching frequency requirements of the circuit design.

Part Context

This part belongs to the BYM11 series of Superectifier fast switching rectifiers. The series offers various voltage ratings ranging from 50 V to 1000 V within the same GL41 package outline. The E3 suffix indicates RoHS compliance and adherence to JESD 201 class 1A whisker testing standards. The RGL41x designation refers to the specific mechanical case style used for these surface-mount devices.

Replacement Considerations

Direct substitutes within the same family include BYM11-500-E3/96, BYM11-600-E3/96, and BYM11-800-E3/96, which share identical package and electrical current specifications but differ in reverse voltage ratings. Ensure the replacement part number matches the required voltage withstand capability for the specific circuit node.

FAQ

What does the polarity marking on the device indicate?

Two bands indicate the cathode end. The first band denotes the device type, and the second band denotes the repetitive peak reverse voltage rating.

Is the BYM11-400-E3/96 qualified for automotive applications?

The standard commercial grade version is not explicitly listed as AEC-Q101 qualified. Automotive qualification typically requires specific ordering codes designated with HE3 suffixes.

What is the maximum thermal resistance from junction to ambient?

The maximum thermal resistance from junction to ambient (RθJA) is 75 °C/W, measured on a copper pad area of 0.24" x 0.24" (6.0 mm x 6.0 mm).
