Product details
Overview
BZB84-C10,215 from Nexperia is a dual common-anode Zener diode in SOT23 package, designed for precision voltage regulation and overvoltage protection in compact PCB layouts. It delivers nominal 10 V Zener voltage (9.4–10.6 V), ±5 % tolerance, 150 Ω typical differential resistance at 5 mA, 300 mW total power dissipation, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the BZB84-C10,215 datasheet, BZB84-C10,215 pinout, BZB84-C10,215 application, or BZB84-C10,215 equivalent, this device serves as a space-efficient dual-Zener solution for bidirectional clamping, reference voltage generation, and ESD-robust signal conditioning in automotive body control modules, industrial sensor interfaces, and power supply feedback networks.
Technical Context
This dual-Zener diode integrates two identical 10 V Zener elements sharing a common anode (Pin 3), enabling symmetrical clamping of AC signals or independent regulation paths with shared thermal coupling. Its SOT23 footprint supports high-density surface-mount assembly while maintaining thermal resistance of 100 K/W junction-to-solder-point.
Rated for non-repetitive peak reverse power up to 40 W (100 µs square wave), it sustains 3.0 A peak reverse current at 10 V and exhibits low 90 pF capacitance at 0 V - critical for high-frequency transient suppression without signal distortion.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 9.4 V to 10.6 V at IZ = 5 mA - defines stable regulation window for 10 V reference circuits |
| Tolerance | ±5 % - enables cost-effective selection for non-critical voltage references where tight accuracy is not required |
| Differential Resistance (rdif) | 150 Ω typical at IZ = 5 mA - determines regulation stiffness and output impedance in shunt regulator designs |
| Total Power Dissipation (Ptot) | 300 mW at Tamb ≤ 25 °C - sets maximum continuous DC power handling before thermal derating |
| Non-repetitive Peak Reverse Current (IZSM) | 3.0 A at tp = 100 µs - supports robust surge immunity in automotive load-dump and ISO 7637-2 pulse testing |
| Junction Temperature (Tj) | −55 °C to +150 °C - ensures operation across extended automotive under-hood environments |
| AEC-Q101 Qualified | Yes - validated for automotive electronics per stress test standard, including temperature cycling and HTRB |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mount package: 3-pin, small-outline transistor outline with 1.3 mm pitch, 2.9 mm × 1.3 mm footprint, and 1.1 mm height - optimized for automated pick-and-place and reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (Diode 1) | Provides first regulated Zener path; connects to protected node or reference point |
| 2 | Cathode (Diode 2) | Enables second independent or mirrored Zener function; supports bidirectional clamping when used with Pin 1 |
| 3 | Common Anode | Shared return path for both Zeners; ties to ground or negative rail in shunt regulator configurations |
Key Features
| Feature | Design Value |
|---|---|
| Dual common-anode configuration | Reduces component count and board area vs. discrete dual-Zener solutions; simplifies layout for symmetric clamping |
| ±5 % Zener voltage tolerance (C-series) | Offers tighter regulation than general-purpose Zeners while balancing cost and performance for industrial sensing |
| AEC-Q101 qualification | Validates reliability for automotive applications including body electronics, lighting control, and infotainment power rails |
| Low 90 pF capacitance at 0 V | Minimizes high-frequency loading on signal lines - suitable for CAN bus termination and RS-485 interface protection |
| 40 W non-repetitive peak power rating | Withstands short-duration transients per ISO 7637-2 Pulse 1/2a/5a without degradation, extending system-level surge margin |
Applications
| Automotive Body Control Unit (BCU) | Industrial Sensor Signal Conditioning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZB84-B10,215 | ±2 % tolerance (tighter), higher rdif (170 Ω typ), same 10 V nominal and SOT23 package | Better for precision reference circuits requiring <0.2 % initial accuracy; less tolerant of current variation | Select when reference stability dominates cost sensitivity; verify thermal derating at >150 °C junction temp |
| MMBZ5240BLT1G | Single 10 V Zener, ±5 %, SOT23, 500 mW Ptot, but no dual configuration or AEC-Q101 rating | Lacks bidirectional clamping capability; unsuitable for automotive or high-reliability signal protection | Use only in non-automotive consumer applications where dual functionality is unnecessary and higher power margin is needed |
Compared with BZB84-B10,215, the C-tolerance version trades initial accuracy for lower cost and broader process yield; versus MMBZ5240BLT1G, it adds functional redundancy and automotive qualification at the expense of single-diode power headroom.

FAQ
What is the maximum continuous forward current for BZB84-C10,215?
The absolute maximum forward current is 200 mA per diode, as specified in Table 5 of the datasheet. This rating applies under steady-state conditions with ambient temperature ≤25 °C and assumes proper PCB thermal design. Exceeding this value risks irreversible junction damage due to thermal runaway.
Can BZB84-C10,215 be used for bidirectional ESD protection?
Yes - its dual common-anode structure allows Cathode 1 and Cathode 2 to clamp positive and negative transients respectively to the common anode (ground). With 3.0 A peak reverse current capability and 40 W surge rating, it meets IEC 61000-4-2 Level 4 (15 kV air/8 kV contact) when properly decoupled with series impedance.
How does temperature affect the Zener voltage of BZB84-C10,215?
At 10 V nominal, the temperature coefficient is +4.5 mV/K (typical), meaning VZ increases by ~4.5 mV per °C rise in junction temperature. This positive drift is confirmed in Figure 4 of the datasheet and must be accounted for in precision reference designs operating above 70 °C ambient.
Is the SOT23 package lead-free and RoHS compliant?
Yes - BZB84-C10,215 is manufactured with lead-free terminations and complies with EU RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. The device uses SnAgCu solder finish and is qualified for standard Pb-free reflow profiles per J-STD-020.
