Product details
Overview
BZB84-C27,215 from Nexperia is a dual common-anode Zener diode in SOT23 package, rated for 27 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 and industrial power rails.
For engineers reviewing the BZB84-C27,215 datasheet, BZB84-C27,215 pinout, BZB84-C27,215 application, or BZB84-C27,215 equivalent, this page delivers verified Zener voltage range (25.1–28.9 V), differential resistance (300 Ω max), temperature coefficient (18.9–25.3 mV/K), and AEC-Q101 qualification status - all critical for precision clamping and stable reference design.
Technical Context
This dual-Zener device integrates two independent Zener diodes sharing a common anode (Pin 3), enabling bidirectional voltage clamping or complementary reference generation from a single footprint. Its ±5 % VZ tolerance and 0.05 µA reverse current at 21.4 V support tight regulation in low-power sensing and feedback paths.
Designed for surface-mount reliability, it features AEC-Q101 qualification, 150 °C maximum junction temperature, and thermal resistance of 417 K/W (junction-to-ambient), making it suitable for under-hood automotive modules and thermally constrained industrial PCBs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 25.1 V to 28.9 V at IZ = 2 mA - defines clamping window for 27 V rail protection |
| Tolerance | ±5 % - enables predictable voltage margining without binning |
| Total Power Dissipation | 300 mW at Tamb ≤ 25 °C - sets continuous DC power limit for thermal design |
| Non-repetitive Peak Power | 40 W (tp = 100 µs) - supports transient surge suppression per diode |
| Differential Resistance | ≤300 Ω at IZ = 2 mA - ensures low dynamic impedance for stable regulation |
| Reverse Current | ≤0.05 µA at VR = 21.4 V - guarantees minimal leakage in high-impedance bias networks |
| Temperature Coefficient | 18.9 to 25.3 mV/K - quantifies VZ drift with junction temperature |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mount package: 3-pin, small outline, standard footprint compatible with automated assembly and reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (Diode 1) | Provides Zener breakdown path from Pin 3 (anode) to Pin 1; connects to protected node or reference point |
| 2 | Cathode (Diode 2) | Enables second independent Zener function - allows dual-rail clamping or symmetric voltage limiting |
| 3 | Common Anode | Shared anode connection; ties both diodes to supply rail or ground return, defining bidirectional clamping topology |
Key Features
| Feature | Design Value |
|---|---|
| Dual common-anode configuration | Reduces board space by integrating two Zeners in one SOT23 footprint - eliminates discrete pairing and layout mismatch |
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD - supports under-hood deployment |
| Wide Zener voltage range | 27 V nominal with 25.1–28.9 V min/max spread - accommodates production variation while maintaining system-level margin |
| Low reverse leakage | ≤0.05 µA at 21.4 V - preserves accuracy in high-impedance voltage dividers and sensor biasing circuits |
| Thermal performance | Rth(j-a) = 417 K/W - enables operation up to 150 °C junction temperature with standard FR4 PCB layout |
Applications
| Automotive Body Control Module (BCM) | Industrial PLC Analog Input Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5262BS-7-F | Single Zener (27 V, ±5 %), SOT363 package, 200 mW Ptot, no common-anode topology | Requires two devices for dual-clamp function; higher board area and routing complexity | Select when discrete layout control is preferred or common-anode symmetry is unnecessary |
| BZX84-C27LT1G | Single Zener (27 V, ±5 %), SOT23 package, 300 mW Ptot, no dual-diode integration | Lacks bidirectional clamping capability; needs external anode tie for dual use | Choose for cost-sensitive single-rail regulation where dual functionality is not required |
Compared with MMBZ5262BS-7-F and BZX84-C27LT1G, BZB84-C27,215 uniquely provides integrated dual-Zener functionality in one SOT23 footprint with true common-anode architecture - reducing component count, interconnect inductance, and thermal coupling asymmetry in bidirectional protection designs.

FAQ
What is the maximum continuous forward current rating for BZB84-C27,215?
The absolute maximum forward current is 200 mA per diode, specified under steady-state conditions. This rating assumes proper PCB thermal relief and ambient temperature ≤25 °C; derating is required above that temperature per the Rth(j-a) = 417 K/W thermal resistance value.
Can BZB84-C27,215 be used for bidirectional ESD protection?
No - it is not rated or characterized for IEC 61000-4-2 ESD immunity. Its 40 W non-repetitive peak power rating applies only to unidirectional 100 µs square-wave surges, not nanosecond ESD pulses. For ESD protection, dedicated TVS diodes like PESD5V0S1BA should be used instead.
How does the common-anode configuration affect PCB layout compared to dual discrete Zeners?
The shared anode (Pin 3) eliminates the need for a separate copper pour or trace to tie two anodes together, reducing parasitic inductance and improving symmetry in high-speed clamping paths. It also cuts component count by 50 % and saves ~1.5 mm² board area versus two SOT23 Zeners.
Is the 27 V Zener voltage guaranteed at all operating temperatures?
No - the nominal 27 V rating is specified at Tj = 25 °C. The temperature coefficient (18.9–25.3 mV/K) means VZ increases linearly with junction temperature; at 125 °C, VZ rises by approximately 2.5–3.2 V above the 25 °C value, which must be accounted for in precision reference designs.
