Product details
Overview
BZB984-C6V2,115 from Nexperia is a dual Zener voltage regulator diode in SOT663 package with nominal 6.2 V working voltage, ±5% tolerance, and common-anode configuration for bidirectional regulation or dual-rail reference applications. It delivers 40 Ω typical differential resistance at IZ = 5 mA and supports ESD/surge protection in space-constrained consumer and industrial PCBs.
For engineers reviewing the BZB984-C6V2,115 datasheet, BZB984-C6V2,115 pinout, BZB984-C6V2,115 application, or BZB984-C6V2,115 equivalent, this device serves as a compact, low-power dual-Zener solution where precise 6.2 V clamping, thermal stability (SZ = +2.2 mV/K), and FR4-mountable SMD packaging are critical selection criteria.
Technical Context
This double diode integrates two independent Zener elements sharing a common anode terminal, enabling symmetrical clamping across two signal paths or complementary rail regulation. Its design targets low-current (<200 mA forward, ≤10 mA Zener test current) stabilization and transient suppression without requiring external biasing networks.
The device operates within -55 °C to +150 °C ambient range, with junction-to-ambient thermal resistance of 294 K/W (2 diodes loaded) on standard FR4 PCB. Its 6.2 V nominal Zener voltage exhibits positive temperature coefficient (+2.2 mV/K), ensuring predictable drift under thermal load in non-automotive embedded systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VZ nominal | 6.2 V - precise regulation point for 5 V–6.5 V system rails or logic-level clamping |
| Zener tolerance | ±5% - ensures VZ stays within 5.8 V–6.6 V at IZ = 5 mA for predictable threshold behavior |
| Differential resistance rdif | 40 Ω typ. - low dynamic impedance maintains stable voltage under small-signal load variations |
| Forward voltage VF | ≤0.9 V at IF = 10 mA - enables low-loss conduction in series protection configurations |
| Total power dissipation | 425 mW (2 diodes loaded) - defines maximum continuous thermal budget on standard FR4 PCB |
| Non-repetitive peak power | 40 W (tp = 100 µs) - supports short-duration ESD pulse absorption per IEC 61000-4-2 Level 4 |
| Reverse leakage IR | 6 µA max. at VR = 4.5 V - ensures minimal quiescent current in standby regulation circuits |
Pinout & Package
SOT663 ultra-small flat plastic SMD package (1.7 × 1.5 × 0.5 mm), optimized for high-density layouts and reflow soldering only.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K1) | Cathode 1 | Connects to first Zener cathode; reverse-biased for 6.2 V clamping from CA to K1 |
| 2 (K2) | Cathode 2 | Connects to second Zener cathode; enables independent or mirrored clamping path from CA to K2 |
| 3 (CA) | Common anode | Shared anode node; ties both Zeners to reference potential (e.g., ground or supply rail) |
Key Features
| Feature | Design Value |
|---|---|
| Dual-Zener common-anode topology | Enables single-package bidirectional voltage limiting or dual-rail reference without discrete pairing |
| Ultra-small SOT663 footprint | 1.7 mm × 1.5 mm area saves >60% board space vs. SO-323 dual-diode alternatives |
| 5% VZ tolerance | Guarantees tight regulation window without post-production trimming or binning |
| Positive temperature coefficient | +2.2 mV/K at IZ = 5 mA - predictable upward drift improves thermal margin in warm environments |
| FR4-optimized thermal performance | Rth(j-a) = 294 K/W (2 diodes) - validated for reliable operation on standard single-sided copper PCBs |
Applications
| USB Port ESD Protection | Low-Voltage Microcontroller I/O Clamping |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN2016LFG-7 | Single-channel 6.2 V Zener in SOT-23; no dual-cathode topology | Requires two devices for dual-path clamping; larger total footprint | Select when only one regulated path is needed and board area permits discrete placement |
| BZX84-C6V2,115 | Single Zener in SOT-23; identical VZ and tolerance but no common-anode dual structure | Cannot implement symmetrical clamping without external wiring; higher assembly cost | Choose for legacy designs already using BZX84 footprint or where dual functionality is unnecessary |
Compared with DMN2016LFG-7 and BZX84-C6V2,115, the BZB984-C6V2,115 uniquely integrates two matched Zeners in one ultra-compact package-reducing component count by 50%, eliminating inter-device matching variance, and cutting PCB real estate by ≥40% in dual-clamp topologies.

FAQ
What is the maximum continuous Zener current for BZB984-C6V2,115?
The device does not specify a maximum continuous Zener current directly, but its 425 mW total power dissipation limit at Tamb ≤ 25 °C implies a practical IZ ceiling of ~68 mA (425 mW ÷ 6.2 V). Operation above 10 mA requires derating per thermal resistance curves in the datasheet to avoid exceeding 150 °C junction temperature.
Can BZB984-C6V2,115 be used in avalanche mode for transient suppression?
No-it is designed and characterized exclusively as a Zener-regulated diode operating in reverse breakdown at 6.2 V. Its 40 W non-repetitive peak power rating applies only under defined square-wave surge conditions (tp = 100 µs), not sustained avalanche conduction. Use only within specified limiting values to prevent parametric shift or failure.
Is the common anode (CA) pin internally bonded to both diodes' anodes?
Yes-pin 3 (CA) is the monolithic common anode connection for both integrated Zener structures. Electrical testing confirms continuity between CA and each cathode under reverse bias, and zero forward conduction between K1 and K2, verifying true dual-diode topology with shared anode metallization.
How does the +2.2 mV/K temperature coefficient affect long-term voltage accuracy?
At IZ = 5 mA, VZ increases by 2.2 mV per Kelvin rise in junction temperature. Over a 100 °C rise (25 °C to 125 °C), this yields +220 mV drift-approximately +3.5% of nominal 6.2 V. System-level calibration or compensation algorithms must account for this linear drift in precision reference applications.
