BZX84-B20,215

Single Zener Diodes Overview

The Nexperia BZX84-B20,215 is a low-power voltage regulator diode in the BZX84 series, housed in a small SOT23 (TO-236AB) Surface-Mounted Device plastic package. It features a nominal working voltage of 20 V with a ±2% tolerance range. The device supports a total power dissipation of up to 250 mW and operates within an ambient temperature range of -55 °C to +150 °C. Key electrical characteristics include a maximum differential resistance of 225 Ω at IZ = 5 mA and a reverse current of 55 μA at VR = 18 V.

Single Zener Diodes Selection Notes

Select this component for general-purpose voltage regulation where space is limited. The BZX84-B variant provides tighter voltage tolerance compared to the C series. Ensure the operating junction temperature remains within limits to maintain reliability. Consider thermal resistance values when designing PCB layouts for adequate heat dissipation under continuous load conditions.

Single Zener Diodes Part Context

This part belongs to the Nexperia BZX84 series of voltage regulator diodes. The series offers 37 breakdown voltages across three tolerance grades. The BZX84-B20,215 specifically denotes the 20 V zener variant with 2% tolerance in the standard SOT23 surface-mount package, widely used in consumer and industrial electronics for basic voltage reference and protection tasks.

Single Zener Diodes Replacement Considerations

Compatible substitutes include other manufacturers' Zener diodes in the SOT-23 package with similar 20 V nominal voltage and 250 mW power rating. Verify pinout compatibility (Anode-NC-Cathode) and ensure equivalent thermal and electrical specifications match the original design requirements.
