BZT52H-B3V3

Manufacturer

NXP Semiconductors (Freescale / NXP). Y-IC is a quality distributor of the NXP brand and we will provide you with the best products and services, fast delivery, and professional support

Detailed Description

Single silicon Zener diode with a nominal 3.3 V regulation voltage in a compact SOD123 package. Designed for simple voltage reference, line clamp, and low-power regulation tasks. Although often grouped under IC categories, this is a discrete diode optimized for stable 3.3 V clamping and regulation in space-constrained designs

Key Features

Nominal Zener voltage 3.3 V Vz per NXP specification

Compact SOD123 footprint for dense PCBs

Surface-mount two-lead device with clear cathode band marking

Low leakage and stable operation over temperature

RoHS compliant and lead-free construction

Broad operating temperature range typical of the BZT52 family consult datasheet for exact limits

Proven, widely used Zener series for general electronics

Key Advantages

Simple and cost-effective way to hold or clamp lines around 3.3 V

Small size saves board space and simplifies routing

Reliable, predictable behavior for bias and protection tasks

Easy to design in and replace with many cross-brand equivalents

Strong availability and mature supply chain

Packaging

Type surface-mount Zener diode

Package SOD123 case code 675

Material molded epoxy body with matte-tin plated terminals lead-free and RoHS compliant

Size typical SOD123 outline approximately 2.6 mm x 1.6 to 1.8 mm x about 1.1 mm height consult package drawing for exact dimensions

Pin configuration two terminals cathode identified by the polarity band anode on the opposite end

Thermal characteristics moderate power capability typical of BZT52 family follow datasheet power derating and thermal resistance guidance for your PCB copper area and ambient conditions

Electrical properties nominal Vz 3.3 V test current and tolerance per NXP spec low dynamic resistance low reverse leakage forward drop typical of small-signal diodes consult the datasheet for guaranteed limits and test conditions
