Product details
Overview
BZB84-B8V2,215 from Nexperia is a dual common-anode Zener diode in SOT23 package, rated for 8.2 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 supply rails.
For engineers reviewing the BZB84-B8V2,215 datasheet, BZB84-B8V2,215 pinout, BZB84-B8V2,215 application, or BZB84-B8V2,215 equivalent, this page delivers verified Zener voltage, differential resistance, temperature coefficient, thermal resistance, and AEC-Q101 qualification status - all critical for automotive-grade voltage reference design and transient suppression validation.
Technical Context
This dual-Zener device integrates two identical 8.2 V Zener elements sharing a common anode (Pin 3), enabling bidirectional clamping or dual-rail regulation from a single footprint. Its ±2 % tolerance and 3.2 mV/K temperature coefficient at IZ = 5 mA ensure stable reference performance across −55 °C to +150 °C ambient.
The SOT23 package delivers 417 K/W junction-to-ambient thermal resistance in free air and supports reflow/wave soldering per JEDEC standards. With 150 Ω typical differential resistance at 5 mA and 0.7 µA max reverse current at 6.6 V, it meets tight regulation demands in space-constrained automotive ECUs and industrial signal conditioning circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 8.04 V to 8.36 V at IZ = 5 mA - ensures precise 8.2 V regulation with ±2 % accuracy for reference stability |
| Differential Resistance (rdif) | 150 Ω max at IZ = 5 mA - maintains low output impedance for minimal regulation error under load variation |
| Reverse Current (IR) | 0.7 µA max at VR = 6.6 V - guarantees low leakage in standby mode for battery-sensitive applications |
| Temperature Coefficient (SZ) | +3.2 mV/K at IZ = 5 mA - enables predictable drift compensation in wide-temperature automotive environments |
| Total Power Dissipation (Ptot) | 300 mW at Tamb ≤ 25 °C - supports continuous operation in compact PCB layouts without forced cooling |
| Non-repetitive Peak Power (PZSM) | 40 W at tp = 100 µs - provides robust ESD/TVS-like surge handling for I/O line protection |
| Junction Temperature (Tj) | 150 °C maximum - aligns with AEC-Q101 requirements for under-hood automotive reliability |

FAQ
What is the maximum continuous forward current for BZB84-B8V2,215?
The absolute maximum forward current is 200 mA per diode, as defined in the limiting values table. This rating applies at Tamb ≤ 25 °C with proper PCB thermal relief; derating is required above 25 °C ambient per the thermal resistance curve (Rth(j-a) = 417 K/W). Operation beyond this limit risks irreversible junction failure.
Does BZB84-B8V2,215 support bidirectional voltage clamping?
Yes - its dual common-anode configuration allows one diode to conduct in forward bias (cathode-to-anode) while the other operates in reverse Zener breakdown, enabling symmetrical ±8.2 V clamping between either cathode and the shared anode. This is confirmed in the pinning diagram and used in I/O protection circuits per Figure 4 of the datasheet.
How does the temperature coefficient affect regulation accuracy over temperature?
With a typical +3.2 mV/K coefficient at 5 mA, the Zener voltage increases by ~160 mV from −40 °C to +125 °C ambient. Combined with ±2 % initial tolerance, total variation remains within ±4.5 % across the full automotive range - sufficient for non-critical biasing but requires compensation in metrology-grade references.
Is BZB84-B8V2,215 compatible with lead-free reflow soldering profiles?
Yes - the SOT23 package is qualified for standard lead-free reflow per JEDEC J-STD-020, with peak temperature up to 260 °C for ≤40 seconds. The recommended footprint (Figure 8) uses 0.5 mm solder lands and 0.6 mm solder paste stencil openings to ensure reliable joint formation without tombstoning or voiding.
