KDZVTR3.3B 3.3V Zener Diode | Voltage Regulator for Power Management Circuits
The KDZVTR3.3B is a precision 3.3V Zener diode delivering 1W power dissipation in a compact SOD-123FL package. With ±6.06% voltage tolerance and 80µA ultra-low leakage current, this diode provides stable voltage clamping and reference for power supplies, crypto-miner control boards, and industrial-electronics designs where a discrete Zener is the cleanest way to set a 3.3V rail.
The lead-free, RoHS-compliant construction meets standard environmental requirements, and the -55°C to +150°C operating range covers automotive, industrial, and harsh-deployment envelopes. The compact 2.6×1.6×0.9mm footprint drops into high-density PCBs without compromising thermal performance.
RoHS-Compliant Surface-Mount Diode for Stable 3.3V Reference
Stable 3.3V reference — critical for ASIC miner voltage regulation and PCB protection circuits.
Space-saving design — 2.6×1.6mm footprint for high-density PCB layouts.
High reliability — industrial-grade construction for 24/7 mining operation.
Low-power efficiency — 1V reverse withstand voltage minimises energy loss.
Use this Zener as a discrete 3.3V clamp on power-management rails, voltage-reference for low-power analog blocks, or surge-protection element on input lines that need an absolute upper voltage limit. On crypto-miner control boards, the part is a standard component on bias rails and protection circuits where a low-cost, high-reliability 3.3V clamp is required. Pair with current-limit resistors sized for the expected fault current to dissipate within the 1W rating.
