Product details
Overview
BZB84-B27,215 from Nexperia is a dual common-anode Zener diode in SOT23 package, rated for 27 V nominal Zener voltage (±2 % tolerance), 300 mW total power dissipation, and 40 W non-repetitive peak reverse power. It serves voltage regulation and overvoltage protection functions in compact automotive and industrial power rails.
For engineers reviewing the BZB84-B27,215 datasheet, BZB84-B27,215 pinout, BZB84-B27,215 application, or BZB84-B27,215 equivalent, this page delivers verified electrical parameters, thermal behavior, AEC-Q101 qualification status, and dual-diode configuration details essential for ESD clamp design, reference voltage generation, and bidirectional transient suppression.
Technical Context
This dual Zener diode integrates two independent 27 V Zener elements sharing a common anode terminal (Pin 3), enabling symmetrical clamping of positive and negative transients across a single node. Its ±2 % voltage tolerance and 18.9–25.3 mV/K temperature coefficient support stable regulation under varying thermal conditions.
Designed for surface-mount use on FR4 PCBs, it delivers 1.00 A non-repetitive peak reverse current at 100 µs pulse width and exhibits 300 Ω typical differential resistance at IZ = 2 mA - critical for low-noise reference stability and predictable clamping knee behavior.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 26.5 V to 27.5 V at IZ = 2 mA - tight ±2 % tolerance ensures precise voltage reference in feedback loops. |
| Total Power Dissipation | 300 mW at Tamb ≤ 25 °C - defines continuous DC power handling before thermal derating begins. |
| Non-repetitive Peak Power | 40 W for tp ≤ 100 µs - supports surge immunity against short-duration transients like ISO 7637-2 pulses. |
| Differential Resistance | 300 Ω max at IZ = 2 mA - low impedance improves regulation accuracy under load variation. |
| Reverse Current (IR) | ≤0.05 µA at VR = 20.3 V - minimal leakage preserves battery life in always-on circuits. |
| Junction Temperature | −55 °C to +150 °C - AEC-Q101 qualification confirms suitability for under-hood automotive environments. |
| Package | SOT23 (TO-236AB) - 3-pin surface-mount footprint compatible with standard reflow processes and space-constrained layouts. |
Pinout & Package
SOT23 plastic surface-mounted package (TO-236AB), 3-lead, small-outline transistor outline with standardized solder land pattern per Nexperia's sot023_fr footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (Diode 1) | Provides 27 V Zener breakdown path from cathode to shared anode; used for positive-rail clamping or reference. |
| 2 | Cathode (Diode 2) | Independent 27 V Zener cathode; enables bidirectional clamping when paired with Pin 1 and common anode (Pin 3). |
| 3 | Common Anode | Shared anode connection for both Zener diodes - simplifies PCB routing and enables dual-polarity regulation from one net. |
Key Features
| Feature | Design Value |
|---|---|
| Dual common-anode configuration | Enables symmetrical ±27 V clamping on a single signal line without external wiring - reduces component count in CAN/LIN bus protection. |
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing - suitable for engine control units and ADAS sensors. |
| ±2 % Zener voltage tolerance | Ensures consistent regulation across production lots - eliminates need for post-assembly trimming in precision voltage references. |
| Low 0.05 µA reverse leakage | Minimizes standby current in battery-powered systems - extends operational life in telematics and remote sensing nodes. |
| 417 K/W junction-to-ambient thermal resistance | Defines thermal performance on standard FR4 PCBs - informs layout decisions for copper pour and trace width in high-reliability designs. |
Applications
| Automotive Power Rail Protection | Industrial Sensor Reference |
|---|---|

IC Role / Device Role / Timing Role: Precision Zener voltage source delivering low-drift reference to ADC bias networks and op-amp feedback paths. Use Value: ±2 % tolerance and 18.9–25.3 mV/K tempco enable <1 % total error over −40 °C to +125 °C operating range. |
| USB-C Port ESD Clamp | Programmable Logic Supply Monitor |
Use Scenario: Protecting USB-C CC and VCONN pins from human-body-model (HBM) and IEC 61000-4-2 ESD events. IC Role / Device Role / Timing Role: Low-capacitance (50 pF) dual Zener acting as fast-turn-on transient voltage suppressor between signal and ground. Use Value: 300 Ω differential resistance ensures sharp clamping knee below 30 V - prevents damage to USB-PD controllers during 8 kV contact discharge. |
Use Scenario: Monitoring 27 V auxiliary rail in FPGA or microcontroller carrier boards to trigger brownout reset. IC Role / Device Role / Timing Role: Zener-based comparator input reference with defined threshold and hysteresis via resistor divider. Use Value: 0.05 µA reverse leakage avoids loading the monitored rail; SOT23 size fits dense BGA escape routing zones. |
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-C27,215 | ±5 % Zener tolerance (25.1–28.9 V), higher IR (≤0.05 µA same), identical package and power ratings | Acceptable where cost sensitivity outweighs precision; less suitable for closed-loop feedback references | Select for non-critical biasing or general-purpose clamping where tighter tolerance is unnecessary |
| MMBZ5262B-7-F | Single 27 V Zener, ±5 %, SOT23, 350 mW Ptot, no dual configuration | Requires two devices and extra routing for bidirectional clamping; lacks common-anode integration | Choose only if dual-diode topology is not required and higher power margin is prioritized |
Compared with BZB84-B27,215, the C-series alternative trades voltage precision for cost, while MMBZ5262B sacrifices integration and board space efficiency - making the BZB84-B27,215 optimal for space-constrained, precision-sensitive dual-polarity protection.

FAQ
What is the maximum continuous reverse current the BZB84-B27,215 can sustain?
The device has no specified continuous reverse current rating; its operation is defined by power dissipation limits. At 27 V Zener voltage, sustained current must remain below ~11.1 mA to stay within the 300 mW total power limit at 25 °C ambient. Derating applies above 25 °C per the Rth(j-a) = 417 K/W thermal resistance.
Can BZB84-B27,215 be used for bidirectional TVS protection?
Yes - its dual common-anode structure allows it to clamp both positive and negative transients on a single line relative to ground. With 27 V breakdown in either direction and 40 W peak power capability, it meets basic IEC 61000-4-5 Level 3 surge requirements when properly heatsinked on FR4.
How does the ±2 % tolerance affect circuit accuracy in a reference design?
At 27 V nominal, ±2 % corresponds to a 0.54 V window (26.46 V to 27.54 V). In a resistive divider-based reference, this directly propagates to output voltage error; for sub-0.5 % system accuracy, additional calibration or trimming is required - unlike tighter-tolerance references such as shunt voltage references.
Is the SOT23 package lead-free and RoHS compliant?
Yes - Nexperia confirms the BZB84-B27,215 is manufactured with lead-free terminations and complies with EU RoHS Directive 2011/65/EU and REACH regulations. The device uses SnAgCu (SAC305) solder finish and is qualified for standard Pb-free reflow profiles per J-STD-020.
