Nexperia USA Inc. BZB84-C7V5,215

Overview

BZB84-C7V5,215 from Nexperia is a dual common-anode Zener diode in SOT23 package, rated for 7.5 V nominal Zener voltage (±5 % tolerance), 300 mW total power dissipation, and 40 W non-repetitive peak reverse power. It serves voltage regulation and overvoltage protection functions in automotive body control modules, industrial sensor signal conditioning, and DC-DC feedback loops.

For engineers reviewing the BZB84-C7V5,215 datasheet, BZB84-C7V5,215 pinout, BZB84-C7V5,215 application, or BZB84-C7V5,215 equivalent, this page delivers verified Zener voltage, differential resistance, thermal resistance, AEC-Q101 qualification status, and dual-diode configuration details essential for circuit stability analysis and ESD-hardened design validation.

Technical Context

This dual-Zener device integrates two independent 7.5 V Zener junctions sharing a common anode (Pin 3), enabling bidirectional clamping or complementary reference generation. Its ±5 % voltage tolerance and 80 Ω typical differential resistance at I_Z = 5 mA support stable regulation under varying load currents.

AEC-Q101 qualification confirms suitability for automotive ambient temperatures (−55 °C to +150 °C), while R_th(j-a) = 417 K/W and R_th(j-sp) = 100 K/W define thermal limits for PCB layout and surge handling in transient-prone systems.

FAQ

What is the maximum continuous reverse current the BZB84-C7V5,215 can sustain?

The device supports up to 200 mA forward current (I_F), but its Zener operation is defined at test currents of 1 mA or 5 mA. At 7.5 V, sustained reverse current must remain below the thermal limit: for 300 mW P_tot, maximum average I_Z ≈ 40 mA at 25 °C ambient on standard FR4. Derating applies above 25 °C per R_th(j-a) = 417 K/W.

Can BZB84-C7V5,215 be used for bidirectional ESD protection?

Yes - its dual common-anode structure allows one cathode to clamp positive transients and the other to clamp negative transients relative to the shared anode. With 150 pF junction capacitance and 40 W peak power rating, it meets IEC 61000-4-2 Level 4 (±15 kV air) when properly laid out with short traces and ground plane coupling.

How does the ±5 % tolerance affect regulation accuracy in a 5 V rail monitor?

At V_Z = 7.5 V ±5 %, the actual clamping range is 7.0–7.9 V. When used in a resistor-divider monitor circuit, this translates to ±6 % uncertainty in trip point voltage. For tight 5 V supervision, add a precision comparator or select the ±2 % B-series variant (BZB84-B7V5,215) to reduce error to ±1.6 %.

Is the SOT23 package suitable for reflow soldering with lead-free processes?

Yes - the device is qualified for lead-free reflow per J-STD-020, with peak temperature rating of 260 °C for 10 seconds. The recommended reflow profile uses ramp-to-spike (≤3 °C/s), preheat (150–200 °C), soak (180–200 °C for 60–120 s), and reflow (235–245 °C peak). Standard SOT23 land patterns from Figure 8 apply.
