Nexperia USA Inc. BZB84-C8V2,215

Overview

BZB84-C8V2,215 from Nexperia is a dual common-anode Zener diode in SOT23 package, rated for 8.2 V nominal Zener voltage (±5 % tolerance), 300 mW total power dissipation, and 40 W non-repetitive peak reverse power. It serves as a precision voltage reference and overvoltage clamp in automotive power rails and industrial sensor signal conditioning circuits.

For engineers reviewing the BZB84-C8V2,215 datasheet, BZB84-C8V2,215 pinout, BZB84-C8V2,215 application, or BZB84-C8V2,215 equivalent, key selection criteria include its AEC-Q101 qualification, dual-Zener topology with shared anode, 0.7 µA max reverse current at 6.56 V, and thermal resistance of 100 K/W junction-to-solder-point - critical for compact PCB layouts under transient stress.

Technical Context

This dual Zener diode integrates two independent 8.2 V Zener elements sharing a common anode terminal (Pin 3), enabling bidirectional clamping or complementary reference generation without external node routing. Its differential resistance is 80 Ω at I_Z = 5 mA, supporting stable regulation under dynamic load steps.

Designed for automotive-grade reliability, it operates across −55 °C to +150 °C ambient, with junction temperature limited to 150 °C and qualified per AEC-Q101. The SOT23 footprint supports high-density surface-mount assembly while maintaining 417 K/W junction-to-ambient thermal resistance in free air.

FAQ

What is the maximum allowable reverse voltage before breakdown for BZB84-C8V2,215?

The nominal Zener voltage is 8.2 V with ±5 % tolerance, meaning guaranteed breakdown occurs between 7.7 V and 8.7 V at I_Z = 5 mA. Below 6.56 V, reverse current remains ≤0.7 µA - this is the practical non-breakdown threshold for leakage-critical designs.

Can BZB84-C8V2,215 be used for bidirectional ESD protection?

Yes - its dual cathode/common anode structure allows symmetrical clamping: Pin 1 clamps positive transients to Pin 3, Pin 2 clamps negative transients to Pin 3. With 150 pF junction capacitance and 40 W peak power, it meets IEC 61000-4-2 Level 4 (15 kV air, 8 kV contact) when properly laid out.

How does thermal resistance affect surge handling in real PCB layouts?

R_th(j-sp) = 100 K/W means each watt of transient power raises junction temperature by 100 K above solder point temperature. On a standard FR4 board with tin-plated copper, a 40 W/100 µs pulse causes negligible average heating but requires adequate copper pour under Pin 3 to sustain the instantaneous thermal gradient without metallization fatigue.

Is the marking code 'UP*' on the device body sufficient for full traceability?

Yes - 'UP*' corresponds exclusively to BZB84-C8V2 per Nexperia's official marking table; the asterisk denotes manufacturing location (Hong Kong for '-' variant). Batch traceability is maintained through Nexperia's lot-code system embedded in packaging labels, not the device marking itself.
