BZW50-33BRL

BZW50-33BRL Description

The BZW50-33BRL from STMicroelectronics is a bidirectional Zener-type TVS diode designed for general-purpose transient voltage suppression. Part of the TRANSIL™ BZW50 series, it offers robust protection with a 33V reverse standoff voltage and a 36.6V minimum breakdown voltage. Its 76V maximum clamping voltage @ Ipp ensures effective suppression of transient spikes, while the 5kW peak pulse power (8/20µs) and 789A peak pulse current (10/1000µs) provide high-energy handling capability. Packaged in a through-hole, tape & reel (TR) format, it is RoHS3 compliant and suitable for automated assembly processes.

BZW50-33BRL Features

• Bidirectional Protection: Single-channel design for clamping both positive and negative transients.
• High Power Handling: 5000W peak pulse power (8/20µs) and 789A surge current (10/1000µs) for robust transient suppression.
• Low Clamping Ratio: 76V max clamping voltage ensures minimal stress on protected circuits.
• Low Capacitance: 2875pF @ 1MHz minimizes signal distortion in high-speed applications.
• Reliable Compliance: RoHS3, REACH unaffected, and ECCN EAR99 certified for global use.
• Automation-Friendly: Tape & reel packaging for efficient PCB assembly.

BZW50-33BRL Applications

• Industrial Electronics: Protects control systems, PLCs, and sensors from voltage transients.
