BZW06-33B

BZW06-33B Description

The BZW06-33B from STMicroelectronics is a unidirectional Zener-type TVS diode designed for general-purpose transient voltage suppression. Part of the BZW06, TRANSIL™ series, it offers robust protection with a 33.3V reverse standoff voltage and a 37.1V minimum breakdown voltage. This diode is housed in a DO-15 package and features a 600W peak pulse power dissipation (8/20µs), making it suitable for moderate to high-energy transient events. Its low clamping voltage (69.7V max @ Ipp) ensures effective protection for sensitive circuits.

BZW06-33B Features

• High Power Handling: 600W peak pulse power (8/20µs) and 57A peak pulse current for reliable surge protection.
• Low Capacitance: 450pF @ 1MHz minimizes signal distortion, ideal for high-speed circuits.
• Robust Construction: Through-hole mounting (DO-15) ensures mechanical stability.
• Compliance: ROHS3 compliant, REACH unaffected, and EAR99/ECCN classified for global use.
• Reliability: MSL 1 (Unlimited) moisture sensitivity ensures long shelf life.
