Frequently Asked Questions

What are the key electrical specifications of the BZX84-B20 Zener diode?

The BZX84-B20 offers a 20 V Zener voltage with ±2% tolerance and a maximum power dissipation of 250 mW. Its maximum dynamic impedance is 55 ohm, providing stable clamping behavior across load variations in low-power signal regulation and reference applications.

Which circuit topologies benefit from the BZX84-B20 as an overvoltage clamp or voltage reference?

The BZX84-B20's 20 V Zener with ±2% tolerance suits ESD protection on signal lines, overvoltage clamping in industrial sensor interfaces, and voltage reference circuits in low-power analog designs. Its 250 mW dissipation rating accommodates transient surges typical of these low-current signal-path applications.

How does the SOT-23 package of BZX84-B20 help in space-constrained PCB designs compared to through-hole alternatives?

The BZX84-B20's SOT-23 3-pin SMT footprint is dramatically smaller than through-hole DO-35 or DO-41 packages, enabling placement in tight PCB areas. With 250 mW dissipation and a 20 V Zener rating, it maintains full performance in miniaturized boards for wearables, portable instruments, and compact industrial controllers.
