Nexperia USA Inc. BZX84-C8V2,215

Overview

BZX84-C8V2,215 from Nexperia is a ±5 % tolerance Zener voltage regulator diode in SOT23 (TO-236AB) package, rated for 8.2 V nominal breakdown at 5 mA, with 80 Ω max differential resistance, 0.7 μA max reverse current at 6.56 V, and 3.2 mV/K temperature coefficient. It delivers stable reference voltage in low-power analog circuits and power supply feedback paths.

For engineers reviewing the BZX84-C8V2,215 datasheet, BZX84-C8V2,215 pinout, BZX84-C8V2,215 application, or BZX84-C8V2,215 equivalent, this page provides verified Zener voltage, thermal resistance, reverse current limits, differential resistance, and cathode/anode terminal mapping - all confirmed from Nexperia's Rev. 7 product data sheet.

Technical Context

This device operates as a two-terminal shunt voltage reference, maintaining regulation by conducting reverse current above its specified Zener voltage. Its 8.2 V nominal working voltage is defined at I_Z = 5 mA, with guaranteed 7.7 V to 8.7 V tolerance band per the ±5 % grade.

Thermal performance is characterized by R_th(j-a) = 500 K/W (free air) and R_th(j-sp) = 330 K/W (solder point), enabling predictable derating in PCB-mounted applications. Non-repetitive peak reverse power dissipation reaches 40 W for 100 μs pulses at T_j = 25 °C.

FAQ

What is the maximum continuous reverse current this diode can handle at 8.2 V?

The BZX84-C8V2,215 is not rated for continuous reverse current at its Zener voltage; it is specified for regulated operation at I_Z = 5 mA. At that condition, power dissipation is 41 mW (8.2 V × 5 mA), well within its 250 mW limit. Continuous operation beyond 200 mA forward current or sustained reverse current exceeding thermal limits will cause junction overheating.

Can Pin 2 be used as a thermal pad or grounded for improved heat dissipation?

No - Pin 2 is explicitly marked "n.c." (not connected) in Nexperia's official pinning diagram and internal construction. It has no electrical or thermal connection to the die. Using it as a thermal pad or grounding it may cause mechanical stress or unintended shorts, and provides no thermal benefit since R_th(j-sp) is defined at the cathode tab (Pin 3), not Pin 2.

How does the +3.2 mV/K temperature coefficient affect regulation accuracy over −40 °C to +125 °C?

Across that 165 K range, the Zener voltage shifts by +3.2 mV/K × 165 K = +528 mV, resulting in a total V_Z span of approximately 7.7 V to 9.2 V. This 19 % deviation relative to nominal 8.2 V means the device is best suited for applications where absolute voltage stability is secondary to threshold detection or coarse regulation.

Is this part qualified for automotive applications?

No - per Nexperia's Rev. 7 datasheet revision history, the BZX84 series was changed to non-automotive qualification in 2023. Automotive-grade alternatives (e.g., BZX84-Q series) require separate part numbers and undergo AEC-Q200 stress testing; BZX84-C8V2,215 lacks those qualifications and is intended for industrial, consumer, and computing use only.
