The BYM11-1000HE3_B/I is a fast recovery rectifier from Vishay, rated at 1 A forward current and 1000 V repetitive reverse voltage. It features a 500 ns reverse recovery time and operates within a temperature range of -65 °C to +175 °C junction temperature. The component utilizes a MELF (DO-213AB) surface-mount package. Official documentation explicitly designates this specific part number as 'NOT FOR NEW DESIGN', indicating it is a legacy item within the manufacturer's portfolio.
Verify availability carefully as this component is marked 'NOT FOR NEW DESIGN'. Sourcing may be limited to existing stock or obsolete channels rather than standard production runs. Confirm exact lot dates and storage conditions if procuring from secondary distributors. Ensure final assembly schedules can accommodate potential supply constraints associated with end-of-life products.
This device is suitable for designs requiring robust fast recovery performance in compact MELF packages. Engineers should prioritize alternative Vishay parts from the same family that are actively recommended for new designs. Evaluate thermal management requirements given the 175 °C maximum junction rating. Consider pin compatibility if substituting into existing footprints.
Part of the SUPERECTIFIER series by Vishay General Semiconductor - Diodes Division. This line focuses on high-reliability fast recovery diodes utilizing advanced silicon planar technology. The BYM11 series specifically targets applications needing low reverse recovery charge and high surge capability in small surface-mount formats.
BYM11-1000-E3/96 is listed as a parametric equivalent substitute. Verify package dimensions and electrical specifications match before integration.
