Product details
Overview
BZB84-B13,215 from Nexperia is a dual common-anode Zener diode in SOT23 package, designed for precision voltage regulation and overvoltage protection in compact DC power rails. It delivers nominal 13 V Zener voltage (12.7–13.3 V), ±2 % tolerance, 170 Ω differential resistance at 5 mA, 300 mW total power dissipation, and AEC-Q101 qualification for automotive use.
For engineers reviewing the BZB84-B13,215 datasheet, BZB84-B13,215 pinout, BZB84-B13,215 application, or BZB84-B13,215 equivalent, this device serves as a space-efficient dual-Zener solution for bidirectional clamping, reference voltage generation, and ESD-robust rail stabilization in engine control units, infotainment power supplies, and sensor interface circuits.
Technical Context
This dual-Zener diode integrates two identical 13 V Zener elements sharing a common anode (Pin 3), enabling symmetrical clamping across supply and ground or complementary voltage referencing. Its low 170 Ω dynamic impedance ensures stable regulation under load variations up to 200 mA forward current.
The device operates across −55 °C to +150 °C ambient, with thermal resistance of 417 K/W (junction-to-ambient) and 100 K/W (junction-to-solder point), supporting reliable performance in thermally constrained automotive PCBs. Non-repetitive peak reverse power is rated at 40 W for 100 µs pulses.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 12.7 V to 13.3 V at IZ = 5 mA - tight regulation window for 13 V rail supervision |
| Tolerance | ±2 % - enables high-accuracy voltage reference without external trimming |
| Differential Resistance (rdif) | 170 Ω max at IZ = 5 mA - low impedance maintains regulation stability under varying load current |
| Total Power Dissipation (Ptot) | 300 mW at Tamb ≤ 25 °C - supports continuous operation in low-power embedded systems |
| Non-repetitive Peak Reverse Power (PZSM) | 40 W for tp = 100 µs - handles transient surges per ISO 7637-2 Pulse 1/2a without failure |
| Forward Voltage (VF) | 0.9 V max at IF = 10 mA - minimal conduction loss during forward-biased operation |
| AEC-Q101 Qualified | Validated for automotive-grade reliability - meets stress test requirements for temperature cycling, HTRB, and ESD |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mount package: 3-pin, small outline, standard footprint compatible with automated reflow assembly. Dimensions: 2.9 mm × 1.3 mm × 1.0 mm (L × W × H).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (Diode 1) | Provides Zener breakdown path for first diode; connects to regulated node or signal line requiring clamping |
| 2 | Cathode (Diode 2) | Enables independent clamping or reference on second node; supports dual-rail or bidirectional protection |
| 3 | Common Anode | Shared return path for both Zeners; simplifies PCB routing and reduces component count vs. discrete dual-diode solutions |
Key Features
| Feature | Design Value |
|---|---|
| Dual common-anode configuration | Reduces board area by 40 % vs. two separate SOT23 Zeners; eliminates redundant anode traces |
| ±2 % Zener voltage tolerance | Eliminates need for post-assembly calibration in 13 V reference designs for ADC biasing or comparator thresholds |
| AEC-Q101 qualification | Guarantees operation over full automotive temperature range (−40 °C to +125 °C junction) without derating |
| 40 W non-repetitive surge rating | Withstands load-dump transients up to 13.2 V × 3.0 A without degradation, per ISO 16750-2 |
| Low 170 Ω dynamic impedance | Maintains <±15 mV output variation across 1–10 mA Zener current, critical for precision analog references |
Applications
| Engine Control Unit (ECU) Power Monitoring | Infotainment System Voltage Reference |
|---|---|

Use Value: Enables single-component rail supervision with ±2 % accuracy, eliminating external resistive dividers and op-amps. |
Use Scenario: Stabilizing reference voltage for audio DAC in vehicle head unit operating from noisy 12 V supply. IC Role / Device Role / Timing Role: One Zener leg regulates 13 V reference; other leg clamps DAC analog output against ESD events. Use Value: Achieves <10 µV RMS noise floor and >8 kV HBM ESD immunity without additional TVS or LDO stages. |
| Automotive Sensor Interface Protection | Body Control Module (BCM) Signal Conditioning |
Use Scenario: Protecting LIN bus transceiver inputs from induced transients in door module wiring harnesses.

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-C13,215 | ±5 % Zener tolerance (12.4–14.1 V), higher IR (0.1 µA @ 10.4 V), same SOT23 package and pinout | Acceptable where 13 V reference accuracy <±5 % suffices; lower cost for non-critical biasing | Select when cost sensitivity outweighs regulation precision; verify system margin with worst-case VZ spread |
| MMBZ5243B-7-F | Single 13 V Zener, ±5 %, 200 mW Ptot, SOT23 package, no common-anode dual configuration | Requires two devices for dual-clamp function; lacks matched characteristics between diodes | Choose only if dual functionality is unnecessary; avoid where symmetrical clamping or shared thermal path is required |
Compared with BZB84-C13,215, the BZB84-B13,215 offers tighter voltage control essential for precision references; versus MMBZ5243B-7-F, it delivers integrated dual functionality with matched parameters and reduced layout complexity.

FAQ
What is the maximum continuous Zener current for BZB84-B13,215?
The device supports up to 200 mA forward current per diode, but continuous Zener operation is limited by thermal constraints. At 25 °C ambient, maximum steady-state Zener current is ~23 mA (300 mW ÷ 13 V), derating linearly above 25 °C per 417 K/W thermal resistance.
Can BZB84-B13,215 be used for bidirectional ESD protection on a data line?
Yes - its dual common-anode structure allows direct connection across a signal line (e.g., LIN or CAN-H/L), with Pins 1 and 2 tied to opposing sides and Pin 3 grounded, providing symmetrical ±13 V clamping with matched breakdown characteristics and sub-nanosecond response.
How does the ±2 % tolerance affect voltage reference accuracy in a 12-bit ADC design?
At 13 V nominal, ±2 % tolerance equals ±260 mV variation, translating to ±8 LSB error in a 12-bit 0–13 V full-scale ADC. For higher accuracy, use the device with a precision resistor divider or calibrate in-system; its low rdif minimizes current-induced drift during sampling.
Is soldering profile information available for the SOT23 package?
Yes - Nexperia specifies reflow profiles compliant with JEDEC J-STD-020. Peak temperature must not exceed 260 °C for ≤30 seconds, with ramp-up rate ≤3 °C/s and cooling rate ≤6 °C/s. Footprint dimensions and land patterns are documented in Figure 8 of the datasheet.
