Product details
Overview
BZB84-B10,215 from Nexperia is a dual common-anode Zener diode in SOT23 package, designed for precision voltage regulation and transient suppression in compact PCB layouts. It delivers nominal 10 V Zener voltage (9.8–10.2 V), ±2 % tolerance, 150 Ω typical differential resistance at 5 mA, and supports non-repetitive peak reverse power up to 40 W - used in automotive ECU power rail clamping and industrial sensor signal conditioning.
For engineers reviewing the BZB84-B10,215 datasheet, BZB84-B10,215 pinout, BZB84-B10,215 application, or BZB84-B10,215 equivalent, this page provides verified pin functions, thermal derating guidance, AEC-Q101 qualification status, dual-diode configuration implications, and direct substitution options with documented voltage/tolerance/thermal differences.
Technical Context
This dual Zener diode integrates two independent 10 V Zener elements sharing a common anode (Pin 3), enabling bidirectional voltage clamping or complementary reference generation without external node tying. Its SOT23 footprint supports high-density routing while maintaining thermal resistance of 100 K/W junction-to-solder-point under standard FR4 mounting.
The device operates across −55 °C to +150 °C ambient, with temperature coefficient of +4.5 mV/K at 5 mA, and exhibits 90 pF capacitance at 0 V - critical for high-frequency noise suppression in CAN/LIN bus interfaces and ADC reference stabilization.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 9.8 V to 10.2 V at IZ = 5 mA - ensures stable 10 V reference within ±2 % over production lot and temperature |
| Differential Resistance (rdif) | 150 Ω max at IZ = 5 mA - limits output impedance drift during load transients in feedback loops |
| Reverse Current (IR) | 0.2 µA max at VR = 7.5 V - guarantees low leakage in battery-backed circuits and high-impedance sensing nodes |
| Non-repetitive Peak Power (PZSM) | 40 W at tp = 100 µs - enables robust ESD/inductive spike absorption per diode without derating |
| Total Power Dissipation (Ptot) | 300 mW at Tamb ≤ 25 °C - defines continuous DC power budget for dual-diode operation on standard FR4 |
| Junction Temperature (Tj) | 150 °C maximum - sets upper thermal limit for reliability in under-hood automotive environments |
| AEC-Q101 Qualified | Yes - validated for automotive-grade stress testing including HTGB, HTRB, and temperature cycling |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mount package: 3-pin, 1.3 mm × 2.9 mm × 1.1 mm body, gull-wing leads, tin-plated terminations compatible with lead-free reflow.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (Diode 1) | Provides Zener breakdown path for first 10 V element; connects to regulated node or clamp target |
| 2 | Cathode (Diode 2) | Enables second independent 10 V clamping path - supports dual-rail protection or split-supply references |
| 3 | Common Anode | Shared anode node; must be tied to system ground or bias reference point for both diodes to function |
Key Features
| Feature | Design Value |
|---|---|
| Dual common-anode topology | Reduces component count vs. discrete dual-Zener solutions; eliminates need for external anode tie trace |
| ±2 % Zener tolerance (B-series) | Enables tighter regulation margins than ±5 % C-series - critical for precision analog front-ends |
| AEC-Q101 qualification | Validates suitability for automotive powertrain and body control modules without additional qualification effort |
| 417 K/W junction-to-ambient Rth | Defines natural convection cooling limit - requires thermal relief or copper pour above 150 mW sustained dissipation |
| 90 pF capacitance at 0 V | Minimizes high-frequency loading on clock lines or RF-sensitive inputs when used as ESD shunt |
Applications
| Automotive ECU Power Rail Clamping | Industrial Sensor Signal Conditioning |
|---|---|
Use Scenario: Protecting 12 V supply rails in engine control units against load dump transients up to 40 V. IC Role / Device Role / Timing Role: Dual Zener acts as bidirectional clamp between VBAT and ground, with Pin 3 grounded and Pins 1/2 connected to protected rail. Use Value: 40 W non-repetitive surge rating absorbs ISO 7637-2 Pulse 5a energy without failure; ±2 % tolerance maintains MCU brown-out threshold accuracy. |
Use Scenario: Stabilizing 10 V reference for 16-bit ADCs measuring thermocouple or strain gauge outputs. IC Role / Device Role / Timing Role: Provides low-noise, temperature-compensated reference via one diode; second diode unused or configured as backup. Use Value: +4.5 mV/K tempco matches typical op-amp offset drift; 150 Ω rdif ensures <1 LSB error under 100 µA load variation. |
| USB-C Port Overvoltage Protection | Programmable Logic Controller (PLC) Input Stage |
Use Scenario: Safeguarding USB-C CC line receivers from accidental 20 V adapter misconnection. IC Role / Device Role / Timing Role: Configured as back-to-back Zeners (Pins 1 & 2 to CC line, Pin 3 to GND) for ±10 V clamping window. Use Value: 90 pF capacitance avoids signal integrity degradation at 100 MHz USB 2.0 data rates; SOT23 footprint fits tight connector zones. |
Use Scenario: Level-shifting and surge protection for 24 V digital inputs in factory automation I/O modules. IC Role / Device Role / Timing Role: One diode clamps positive transients to +10 V rail; second diode clamps negative excursions to −10 V (with external bias). Use Value: Dual configuration replaces two discrete Zeners and one resistor, reducing BOM count by 33 % and PCB area by 40 %. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5240BS-7-F | Single Zener (10 V, ±5 %), SOT363 package, 200 mW Ptot, no common-anode topology | Requires external anode tie for dual use; higher tolerance increases reference uncertainty | Select only if space allows separate anode routing and ±5 % regulation is acceptable |
| BZX84-B10,215 | Single Zener (10 V, ±2 %), same SOT23 package, identical ZV spec but no dual functionality | Cannot perform bidirectional clamping or dual-rail referencing without adding second device | Choose when only one 10 V reference is needed and board area permits two single-Zener placements |
Compared with BZB84-B10,215, MMBZ5240BS-7-F lacks integrated dual topology and tighter tolerance, increasing design complexity for clamping; BZX84-B10,215 matches voltage accuracy but doubles component count and layout area for dual-function requirements.

FAQ
What is the maximum continuous forward current for BZB84-B10,215?
The absolute maximum forward current is 200 mA per diode, specified under limiting values in accordance with IEC 60134. This rating applies with ambient temperature ≤25 °C and standard FR4 PCB mounting. Derating is required above 25 °C ambient per the thermal resistance of 417 K/W junction-to-ambient.
How does the common-anode configuration affect circuit implementation?
With Pin 3 as shared anode, both Zener cathodes (Pins 1 and 2) must be connected to separate nodes requiring clamping or referencing, while Pin 3 is tied to a common reference (typically ground or bias rail). This enables simultaneous regulation of two independent signals without inter-diode coupling, unlike series or parallel discrete configurations.
Is BZB84-B10,215 suitable for high-frequency ESD protection?
Yes - its 90 pF capacitance at 0 V and 40 W non-repetitive peak power make it effective for IEC 61000-4-2 Level 4 (15 kV air, 8 kV contact) ESD suppression on low-speed digital lines. However, for >100 MHz signal paths (e.g., USB 3.0, HDMI), lower-capacitance TVS diodes are preferred due to bandwidth limitations.
What is the temperature coefficient behavior at 10 V nominal working voltage?
At 10 V nominal Zener voltage, the temperature coefficient is +4.5 mV/K (typical) at IZ = 5 mA, meaning output voltage increases by ~4.5 mV per Kelvin rise in junction temperature. This positive slope helps compensate for negative tempcos in associated op-amps or voltage references in precision analog designs.
