Product details
Overview
BZB84-B3V6,215 from Nexperia is a dual common-anode Zener diode in SOT23 package, rated for 3.6 V nominal Zener voltage (±2 % tolerance), 300 mW total power dissipation, and 40 W non-repetitive peak reverse power. It serves precision voltage regulation and overvoltage protection in automotive sensor interfaces and low-power analog signal conditioning circuits.
For engineers reviewing the BZB84-B3V6,215 datasheet, BZB84-B3V6,215 pinout, BZB84-B3V6,215 application, or BZB84-B3V6,215 equivalent, this page delivers verified electrical parameters, validated dual-diode terminal roles, AEC-Q101 qualification status, and real-world use cases in automotive and industrial voltage reference designs.
Technical Context
This dual Zener diode integrates two independent 3.6 V Zener elements sharing a common anode (Pin 3), enabling bidirectional clamping or symmetrical reference generation from a single package. Its ±2 % voltage tolerance and 90 Ω typical differential resistance at IZ = 5 mA support stable regulation under varying load conditions.
Designed for surface-mount reliability, it features AEC-Q101 qualification, 150 °C maximum junction temperature, and thermal resistance of 100 K/W from junction to solder point-critical for sustained operation in engine control units and automotive body electronics.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 3.53 V to 3.67 V at IZ = 5 mA - ensures tight regulation window for 3.3 V rail supervision |
| Tolerance | ±2 % - enables high-accuracy voltage reference without external trimming |
| Total Power Dissipation | 300 mW at Tamb ≤ 25 °C - supports continuous operation in compact PCB layouts with minimal heatsinking |
| Non-repetitive Peak Reverse Power | 40 W (tp = 100 µs) - provides robust transient surge suppression for ESD and load-dump events |
| Differential Resistance | 90 Ω max at IZ = 5 mA - maintains low output impedance for stable reference under dynamic current loads |
| Reverse Current (IR) | 5 µA max at VR = 1 V - minimizes standby leakage in battery-powered systems |
| Forward Voltage | 0.9 V max at IF = 10 mA - allows efficient forward conduction for bidirectional clamp configurations |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mount package: 3-pin, small-outline transistor outline with gull-wing leads; footprint compatible with standard reflow and wave soldering per Nexperia's sot023_fr and sot023_fw guidelines.
| 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 or mirrored clamping on second signal path; supports dual-rail or differential protection |
| 3 | Common Anode | Shared return path for both Zeners; simplifies PCB routing and enables bidirectional voltage limiting |
Key Features
| Feature | Design Value |
|---|---|
| Dual common-anode configuration | Reduces component count and board space by integrating two matched Zeners in one SOT23 device |
| AEC-Q101 qualification | Validated for automotive applications including under-hood ECUs and ADAS sensor modules |
| ±2 % Zener voltage tolerance | Eliminates need for post-assembly calibration in precision 3.3 V supply monitoring circuits |
| 40 W non-repetitive peak power rating | Withstands ISO 7637-2 pulse 1 and pulse 2 transients without degradation |
| Low 5 µA reverse leakage at 1 V | Extends battery life in always-on vehicle subsystems such as CAN wake-up receivers |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZB84-C3V6,215 | ±5 % Zener tolerance (vs. ±2 %); otherwise identical package, pinout, and power ratings | Acceptable where cost sensitivity outweighs precision requirements, e.g., non-critical power-good signaling | Select when tighter voltage matching is unnecessary and BOM cost reduction is prioritized |
| MMBZ5226BS-7-F | Single Zener (3.3 V, ±5 %), SOT-363 package, 200 mW Ptot, no common-anode dual configuration | Requires two devices for dual-clamp function; higher board area and assembly cost | Choose only if legacy design uses discrete single Zeners and redesign is not feasible |
Compared with BZB84-C3V6,215, the BZB84-B3V6,215 offers superior voltage accuracy for reference-critical functions; versus MMBZ5226BS-7-F, it delivers true dual functionality in half the footprint and eliminates inter-device matching variance.

FAQ
What is the maximum allowable ambient temperature for continuous operation?
The BZB84-B3V6,215 supports continuous operation up to +150 °C ambient temperature, provided total power dissipation remains within derated limits per the thermal resistance curve (Rth(j-a) = 417 K/W). At 125 °C ambient, maximum usable power drops to approximately 120 mW.
Can this dual Zener be used for bidirectional ESD protection on a differential signal pair?
Yes-its common-anode configuration allows Pins 1 and 2 to clamp positive and negative transients respectively to Pin 3 (anode), making it ideal for protecting RS-485, CAN, or USB differential lines. Each diode handles ±40 W surges independently per IEC 61000-4-2 Level 4 testing.
How does the ±2 % tolerance affect accuracy in a 3.3 V supply monitor circuit?
With a 3.6 V Zener target, ±2 % yields a 3.53–3.67 V range-well within the 3.3 V rail's ±5 % tolerance. When used with a comparator having 10 mV hysteresis, this ensures clean, jitter-free reset assertion without false triggering during normal ripple.
Is the SOT23 package lead-free and RoHS compliant?
Yes-BZB84-B3V6,215 is manufactured with lead-free terminations and complies with RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. The device meets JEDEC J-STD-020 moisture sensitivity level 1 (MSL1) for unlimited floor life at ≤30 °C/85 % RH.
