Product details
Overview
BZX84-B6V2,215 from Nexperia is a ±2 % tolerance Zener voltage regulator diode in SOT23 (TO-236AB) package, rated for 6.2 V nominal breakdown voltage at 5 mA, 250 mW total power dissipation, and 150 °C maximum junction temperature - used for precision low-power voltage reference and overvoltage protection in analog sensor signal conditioning circuits.
For engineers reviewing the BZX84-B6V2,215 datasheet, BZX84-B6V2,215 pinout, BZX84-B6V2,215 application, or BZX84-B6V2,215 equivalent, key selection criteria include Zener voltage tolerance (±2 %), differential resistance (150 Ω max at 5 mA), temperature coefficient (+0.4 to +3.7 mV/K), non-repetitive peak reverse power (40 W), and thermal resistance (330 K/W junction-to-solder-point).
Technical Context
This Zener diode operates in reverse-bias breakdown mode with tightly controlled VZ = 6.08 V to 6.32 V at IZ = 5 mA, exhibiting a positive temperature coefficient of +0.4 to +3.7 mV/K across its operating current range. Its low 150 Ω max differential resistance ensures stable regulation under small-signal load variations.
Designed for surface-mount use on FR4 PCBs with standard SOT23 footprint, it supports pulse operation up to 40 W (100 μs, square wave) and continuous DC dissipation up to 250 mW at Tamb ≤ 25 °C, with thermal resistance from junction to solder point specified at 330 K/W.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.08 V to 6.32 V at IZ = 5 mA - defines precise regulation point for feedback or reference circuits |
| Tolerance | ±2 % - enables tighter voltage margin control than ±5 % C-series variants |
| Differential Resistance (rdif) | ≤150 Ω at IZ = 5 mA - ensures minimal output voltage shift under small load changes |
| Temperature Coefficient (SZ) | +0.4 to +3.7 mV/K at IZ = 5 mA - quantifies VZ drift with junction temperature rise |
| Total Power Dissipation (Ptot) | 250 mW at Tamb ≤ 25 °C on FR4 PCB - sets maximum continuous DC power handling |
| Non-repetitive Peak Reverse Power | 40 W (100 μs, square wave) - supports transient surge suppression without failure |
| Junction Temperature (Tj) | −65 °C to +150 °C - defines safe operating thermal envelope for reliability |
Pinout & Package
Package: SOT23 (TO-236AB), 3-lead surface-mount plastic package with standard footprint per Figure 12 (reflow) and Figure 13 (wave soldering); dimensions per Figure 11 (1.9 mm × 1.3 mm × 1.0 mm).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (A) | Forward-biased terminal; connects to lower-potential node in reverse-regulation configuration |
| 2 | Not Connected (n.c.) | Internal die pad with no electrical connection - must remain unconnected on PCB |
| 3 | Cathode (K) | Reverse-biased terminal; connects to higher-potential node and serves as regulation output reference |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-A6V2,215 | ±1 % tolerance (6.13–6.27 V), lower rdif (≤100 Ω), tighter tempco (−0.2 to +1.2 mV/K) | Higher accuracy required in precision instrumentation references | Select when reference stability dominates cost sensitivity and board space is constrained |
| BZX84-C6V2,215 | ±5 % tolerance (5.8–6.6 V), higher rdif (≤200 Ω), wider tempco (−2.0 to +5.3 mV/K) | Cost-sensitive consumer electronics where coarse regulation suffices | Select for non-critical biasing in high-volume, low-margin products with relaxed spec margins |
Compared with BZX84-A6V2,215, the BZX84-B6V2,215 trades 1 % tolerance and sub-100 Ω rdif for lower unit cost and broader tempco acceptance; versus BZX84-C6V2,215, it delivers twice the voltage accuracy and 25 % lower dynamic impedance at identical price tier.

FAQ
What is the maximum continuous forward current for BZX84-B6V2,215?
The device is not rated for continuous forward conduction; its primary function is reverse-bias Zener operation. Absolute maximum forward current is 200 mA per limiting values table, but sustained forward bias exceeds design intent and risks thermal runaway or parameter shift. Forward voltage is specified only as ≤0.9 V at 10 mA pulse test conditions.
Can BZX84-B6V2,215 be used in parallel for higher power dissipation?
No - Zener diodes exhibit negative temperature coefficients below ~5 V and positive above, but BZX84-B6V2,215 has +0.4 to +3.7 mV/K coefficient, causing current hogging if paralleled due to mismatched VZ and thermal coupling. Parallel operation is not recommended; use a single higher-rated device or external current-sharing resistors if required.
How does the "n.c." pin (Pin 2) affect PCB layout?
Pin 2 is internally unconnected and must remain electrically isolated on the PCB - no copper pour, trace, or solder mask opening should contact it. Its presence maintains mechanical symmetry for pick-and-place accuracy but introduces no electrical function; bridging it to ground or signal risks mechanical stress or solder wicking defects.
Is BZX84-B6V2,215 qualified for automotive applications?
No - per Nexperia's revision history (Section 13), this part is explicitly non-automotive qualified. It lacks AEC-Q101 stress testing and automotive-grade process controls. For automotive use, select the -Q qualified variants (e.g., BZX84-B6V2,215-Q) which undergo extended temperature cycling, humidity testing, and failure analysis per automotive standards.
