Product details
Overview
BZB84-B6V2,215 from Nexperia is a dual common-anode Zener diode in SOT23 package, designed for precision voltage regulation and transient suppression in compact power rails. It delivers 6.08 V to 6.32 V nominal Zener voltage at 5 mA, ≤150 Ω differential resistance, ±2 % tolerance, and supports 6 A non-repetitive peak reverse current under 100 µs surge conditions - used in automotive ECU power monitoring circuits.
For engineers reviewing the BZB84-B6V2,215 datasheet, BZB84-B6V2,215 pinout, BZB84-B6V2,215 application, or BZB84-B6V2,215 equivalent, this page provides verified pin functions, thermal derating guidance, dual-diode configuration implications, and AEC-Q101-qualified automotive suitability details.
Technical Context
This dual Zener diode integrates two independent 6.2 V Zener elements sharing a common anode (Pin 3), enabling bidirectional clamping or dual-rail reference generation from a single footprint. Its ±2 % tolerance and low 150 Ω typical dynamic impedance ensure stable regulation across temperature and load variations.
Rated for 300 mW total power dissipation at Tamb ≤25 °C and qualified to AEC-Q101, it operates reliably from −55 °C to +150 °C junction temperature, with thermal resistance of 417 K/W (junction-to-ambient) on FR4 PCB - critical for under-hood automotive designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.08 V to 6.32 V at IZ = 5 mA - defines precise clamping threshold for 6.2 V rail protection |
| Differential Resistance (rdif) | ≤150 Ω at IZ = 5 mA - ensures minimal voltage shift under varying load current |
| Reverse Current (IR) | ≤3 µA at VR = 4.0 V - guarantees low leakage during standby in battery-powered systems |
| Non-repetitive Peak Current (IZSM) | 6.0 A at tp = 100 µs - supports robust ESD/ISO 7637-2 pulse suppression |
| Total Power Dissipation (Ptot) | 300 mW at Tamb ≤25 °C - sets maximum continuous DC power handling before thermal derating |
| Junction Temperature (Tj) | −55 °C to +150 °C - enables operation in engine control units and transmission modules |
| AEC-Q101 Qualified | Yes - validated for automotive-grade reliability including temperature cycling and HTRB |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mount package: 3-pin, small-outline transistor outline with gull-wing leads; 1.9 mm × 1.3 mm body, 0.95 mm height, standard FR4-compatible footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (Diode 1) | Connects to regulated node requiring 6.2 V clamping; reverse-biased during normal operation |
| 2 | Cathode (Diode 2) | Enables second 6.2 V clamp path - supports redundant sensing or dual-rail referencing |
| 3 | Common Anode | Shared anode tie-point; must be connected to system ground or reference potential for both diodes |
Key Features
| Feature | Design Value |
|---|---|
| Dual common-anode configuration | Reduces PCB area by 50 % vs. two discrete Zeners while maintaining independent cathode routing |
| ±2 % Zener voltage tolerance (B-series) | Eliminates post-assembly calibration in precision 6.2 V reference applications |
| AEC-Q101 qualification | Validated for automotive powertrain and chassis modules per stress test requirements |
| 40 W non-repetitive peak power rating | Handles ISO 7637-2 Pulse 1 (inductive load dump) without failure when properly heatsinked |
| Low 0.9 V forward voltage | Enables use as polarity protection diode in low-voltage auxiliary supplies (e.g., 3.3 V logic rails) |
Applications
| Automotive Engine Control Unit (ECU) | Industrial PLC Analog Input Protection |

FAQ
What is the maximum continuous reverse power the BZB84-B6V2,215 can dissipate?
The BZB84-B6V2,215 has a total power dissipation limit of 300 mW at ambient temperatures ≤25 °C. Derating is required above this temperature at 2.4 mW/°C, based on its 417 K/W junction-to-ambient thermal resistance. This rating applies to combined dissipation across both diodes.
Can Pins 1 and 2 be used simultaneously for clamping different nodes?
Yes - Pins 1 and 2 serve as independent cathodes tied to a shared anode (Pin 3). This allows simultaneous clamping of two separate 6.2 V nodes (e.g., VDD and REF) to the same ground reference, provided each cathode sees appropriate current limiting resistors.
Is the 6.2 V Zener voltage specified at DC or pulsed conditions?
The nominal 6.08 V to 6.32 V Zener voltage is specified at DC test condition: IZ = 5 mA, Tj = 25 °C. Pulse testing (e.g., 100 µs surge) affects peak current capability but not the DC voltage rating, which remains stable due to low differential resistance (≤150 Ω).
How does the temperature coefficient affect regulation accuracy over automotive temperature range?
At 6.2 V, the BZB84-B6V2,215 exhibits a positive temperature coefficient of +0.4 mV/K to +3.7 mV/K. Over −40 °C to +125 °C, this results in ≤±0.6 V drift - mitigated in practice by using the diode within its specified 5 mA operating current and leveraging its tight ±2 % initial tolerance.
