The Nexperia BZX84-C16,215 is a single unidirectional silicon Zener Diode in a 3-pin SOT-23 package, supplied on 3000-piece tape and reel. It has a 16 V nominal Zener voltage with 5 percent tolerance (16.2 V measured at a 5 mA test current), 40 ohms Zener impedance, and a 250 mW power dissipation rating. Reverse leakage is specified at 50 nA maximum with an 11.2 V reverse standoff voltage and 900 mV forward voltage. BZX84-C16,215 is a production-status, lead-free, RoHS-compliant surface-mount device rated -65 C to +150 C.

A Zener Diode conducts in reverse at a well-defined breakdown voltage and holds that voltage nearly constant as current varies, which lets it act as a simple shunt voltage reference or a hard clamp against overvoltage. At 16 V and 250 mW the BZX84-C16,215 is a small-signal part rather than a power clamp, so it is used to set or limit a bias voltage, clamp a gate-drive or control line, protect a low-power input from transient overvoltage, and provide a cheap local reference where a precision IC reference is unnecessary. The SOT-23 body and reel packaging suit automated high-volume assembly. Buyers are typically hardware designers and contract manufacturers across industrial controls, power supplies, consumer electronics and communications equipment.
