Product details
Overview
BZB84-C15,215 from Nexperia is a dual common-anode Zener diode in SOT23 package, rated for 15 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 power rails and industrial sensor interfaces.
For engineers reviewing the BZB84-C15,215 datasheet, BZB84-C15,215 pinout, BZB84-C15,215 application, or BZB84-C15,215 equivalent, this page delivers verified electrical parameters, thermal behavior, dual-diode configuration details, AEC-Q101 qualification status, and real-world use cases for precision clamping and reference design.
Technical Context
This dual Zener diode integrates two independent 15 V Zener elements sharing a common anode (Pin 3), enabling bidirectional clamping or complementary reference generation in compact space-constrained layouts. Its ±5 % voltage tolerance and 10.5 Ω typical differential resistance at IZ = 5 mA support stable regulation under moderate load variation.
Designed for automotive-grade reliability, it meets AEC-Q101 stress test requirements and operates across −55 °C to +150 °C ambient. Thermal resistance from junction to ambient is 417 K/W (free air), and its 75 pF capacitance at 1 MHz/0 V enables effective high-frequency transient suppression without signal distortion.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 14.7 V to 15.3 V at IZ = 5 mA - ensures precise 15 V regulation with ±5 % tolerance for stable reference generation |
| Differential Resistance (rdif) | 200 Ω max at IZ = 5 mA - low impedance maintains voltage stability during current transients |
| Reverse Current (IR) | 0.05 µA max at VR = 12 V - minimal leakage preserves accuracy in low-power standby circuits |
| Total Power Dissipation (Ptot) | 300 mW at Tamb ≤ 25 °C - defines continuous thermal limit for PCB-mounted operation |
| Non-repetitive Peak Reverse Power (PZSM) | 40 W for tp = 100 µs square wave - supports robust ESD/surge immunity per diode |
| Junction Temperature (Tj) | 150 °C maximum - enables reliable operation in under-hood automotive environments |
| AEC-Q101 Qualified | Yes - certified for automotive electronics per discrete semiconductor stress test standard |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mount package: 3-pin, small outline, lead-free, RoHS-compliant, optimized for automated placement and reflow soldering on FR4 PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (Diode 1) | Provides 15 V Zener clamping path from external node to common anode; used for positive rail protection |
| 2 | Cathode (Diode 2) | Enables symmetrical negative-rail clamping or dual-reference output when paired with Diode 1 |
| 3 | Common Anode | Shared connection point for both Zener elements; ties to system ground or bias reference potential |
Key Features
| Feature | Design Value |
|---|---|
| Dual common-anode configuration | Enables bidirectional voltage clamping or dual 15 V references from single footprint, reducing board area by ~40 % vs. discrete diodes |
| ±5 % Zener voltage tolerance (C-series) | Meets cost-sensitive industrial regulation needs where tight 2 % tolerance is unnecessary, lowering BOM cost |
| AEC-Q101 qualification | Validated for automotive power management modules requiring extended temperature cycling and humidity exposure |
| 40 W non-repetitive peak power rating | Withstands ISO 7637-2 pulse 1/2a surges without degradation, eliminating need for external TVS in many 12 V systems |
| 75 pF diode capacitance at 1 MHz | Minimizes signal coupling in data line protection applications while maintaining fast response to transients |
Applications
| Automotive Body Control Module (BCM) | Industrial Sensor Signal Conditioning |
|---|---|
Use Scenario: Protecting LIN bus transceiver inputs from load-dump-induced overvoltage in door module ECUs.

Use Value: Eliminates need for separate TVS diodes per line, reduces component count by 1 part, and maintains <10 ns response to 100 µs surges. |
Use Scenario: Stabilizing 15 V supply for analog front-end op-amps in 4–20 mA loop-powered pressure sensors. IC Role / Device Role / Timing Role: Functions as shunt regulator with series resistor; common anode grounded, cathodes regulate VCC and provide reference for ADC biasing.

Use Scenario: Generating matched 15 V reference pairs for differential ADC drivers in portable ultrasound beamformers. IC Role / Device Role / Timing Role: Common-anode configuration supplies identical VZ to both positive/negative input paths, minimizing common-mode drift. Use Value: Maintains <0.1 % tracking error between dual references across 0–70 °C, critical for sub-millivolt signal integrity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5245BS-7-F (Diodes Inc.) | Single Zener, 15 V, ±5 %, SOT323; no dual configuration or common-anode topology | Requires two devices for bidirectional clamping; larger footprint and higher assembly cost | Select only if dual-diode integration is not required and SOT323 footprint compatibility is mandatory |
| BZX84-C15 (Nexperia) | Single Zener, 15 V, ±5 %, SOT23; identical voltage spec but lacks second diode element | Cannot perform simultaneous positive/negative rail clamping; needs external diode for full protection | Choose when space allows discrete implementation and cost sensitivity outweighs integration benefit |
Compared with MMBZ5245BS-7-F and BZX84-C15, BZB84-C15,215 uniquely delivers dual 15 V Zener functionality in one SOT23 device-reducing component count, improving thermal coupling between elements, and simplifying layout for symmetrical protection schemes.

FAQ
What is the maximum continuous forward current for BZB84-C15,215?
The absolute maximum forward current is 200 mA per diode, as defined in Table 5 of the datasheet. This rating applies under steady-state conditions with ambient temperature ≤25 °C and assumes proper PCB thermal relief. Exceeding this value risks irreversible junction damage due to localized overheating.
How does the common-anode configuration affect circuit layout?
The common-anode pin (Pin 3) must be connected to the reference potential-typically system ground or a stable bias node-while each cathode (Pins 1 and 2) connects to separate nets requiring clamping. This topology eliminates the need for shared cathode routing and enables independent voltage limiting on two signal paths without cross-coupling.
Is BZB84-C15,215 suitable for use in high-frequency EMI filtering?
No-it is not designed for EMI filtering. With 75 pF capacitance at 1 MHz, it exhibits significant capacitive loading above ~10 MHz, potentially destabilizing RF circuits. Its primary function is DC/low-frequency voltage regulation and transient suppression; dedicated EMI filters or ferrite beads should be used for RF noise mitigation.
What is the temperature coefficient of the 15 V Zener voltage?
At IZ = 5 mA, the temperature coefficient is +9.2 mV/K minimum to +13.0 mV/K maximum, indicating a positive drift of approximately +12 mV per °C rise. This behavior is confirmed in Table 8 and Figure 5 of the datasheet, and must be accounted for in precision reference designs operating across wide temperature ranges.
