Product details
Overview
BZB984-C2V4,115 from Nexperia is a dual-cathode, common-anode Zener voltage regulator diode in SOT663 package, rated for 2.4 V nominal Zener voltage with ±5% tolerance, 425 mW total power dissipation (2 diodes), and 0.9 V forward voltage at 10 mA. It serves as a compact, low-power precision reference or clamping element in space-constrained analog monitoring and ESD protection circuits.
For engineers reviewing the BZB984-C2V4,115 datasheet, BZB984-C2V4,115 pinout, BZB984-C2V4,115 application, or BZB984-C2V4,115 equivalent, key selection criteria include its dual-Zener topology with shared anode, tight VZ tolerance, thermal resistance of 294 K/W (2 diodes, free air), and suitability for low-current regulation below 200 mA.
Technical Context
This device integrates two independent Zener diodes sharing a common anode terminal, enabling bidirectional voltage clamping or dual-rail reference generation from a single ultra-small SMD footprint. Its 2.4 V nominal Zener voltage targets low-voltage logic rail stabilization and I/O interface protection where headroom is limited.
Thermal performance is defined for FR4 PCB mounting with single-sided copper: Rth(j-a) = 294 K/W (2 diodes loaded), and maximum junction temperature is 150 °C. Non-repetitive peak reverse power dissipation reaches 40 W for 100 µs pulses, supporting transient surge suppression.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 2.4 V nominal, ±5% tolerance (2.2 V to 2.6 V) - ensures stable low-voltage reference under 5 mA test current |
| Forward Voltage (VF) | ≤ 0.9 V at IF = 10 mA - enables efficient forward conduction in clamp configurations |
| Total Power Dissipation | 425 mW (2 diodes loaded on FR4 PCB) - defines continuous DC or average power handling in dual-diode operation |
| Reverse Current (IR) | ≤ 70 µA at VR = 1 V - confirms low leakage for precision biasing applications |
| Differential Resistance (rdif) | 275 Ω max at IZ = 5 mA - quantifies Zener impedance affecting regulation accuracy under load variation |
| Non-repetitive Peak Power | 40 W at tp = 100 µs - supports ESD/IEC 61000-4-2 level 4 transient suppression without failure |
| Junction Temperature (Tj) | −55 °C to +150 °C - specifies full operational range for industrial ambient environments |
Pinout & Package
Package: SOT663 - ultra-small flat plastic SMD package (1.7 mm × 1.5 mm × 0.5 mm), optimized for high-density PCB layouts and reflow soldering only.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K1) | Cathode 1 | Connects to first Zener cathode; reverse-biased to regulate or clamp at 2.4 V relative to CA |
| 2 (K2) | Cathode 2 | Connects to second Zener cathode; enables independent or mirrored regulation path from same anode |
| 3 (CA) | Common Anode | Shared anode node for both Zeners; simplifies routing in dual-rail or bidirectional clamp topologies |
Key Features
| Feature | Design Value |
|---|---|
| Dual-Zener topology with common anode | Enables compact bidirectional clamping or dual-reference generation without discrete pairing |
| ±5% Zener voltage tolerance | Reduces calibration overhead in low-voltage analog sensing and feedback loops |
| Ultra-small SOT663 footprint (1.7 × 1.5 mm) | Supports miniaturized wearables, IoT sensors, and portable medical devices with strict board area limits |
| 425 mW total dissipation (2 diodes) | Permits simultaneous operation of both Zeners in low-duty-cycle regulation without derating |
| Low 70 µA reverse leakage at 1 V | Minimizes quiescent current draw in battery-powered always-on monitoring circuits |
Applications
| USB Interface Protection | Low-Voltage Microcontroller Reference |

Use Scenario: Protecting USB 2.0 D+ and D− lines from ESD events per IEC 61000-4-2 Level 4. IC Role / Device Role: Dual-Zener clamp referenced to common ground via CA pin, with K1/K2 tied to signal lines. Use Value: 40 W non-repetitive peak power rating absorbs 15 kV contact discharge without degradation, while 2.4 V VZ prevents logic-level overshoot beyond 3.3 V IO rails. |
Use Scenario: Providing stable 2.4 V reference for ADC input scaling in battery-powered sensor nodes. IC Role / Device Role: Precision shunt reference connected between MCU AVDD and GND, with CA grounded and K1/K2 unused or paralleled. Use Value: ±5% VZ tolerance and 275 Ω rdif ensure <1% full-scale error across 0–100 µA load variation, critical for 12-bit measurement accuracy. |
| Industrial Sensor Signal Conditioning | IoT Node Power Rail Clamp |
|
Use Scenario: Clamping 0–2.5 V analog output of pressure transducers against overvoltage during hot-swap or cable fault conditions. IC Role / Device Role: Common-anode Zener pair configured as back-to-back clamp between signal line and 2.4 V reference rail. Use Value: Matched 2.4 V breakdown enables symmetrical ±2.4 V clamping window, preserving signal integrity within 0.1% linearity band up to 10 kHz. |
Use Scenario: Preventing overvoltage damage to 2.4 V LDO outputs during load dump or supply coupling transients in BLE modules. IC Role / Device Role: Zener connected between LDO output and ground (CA = GND, K1 = VOUT), leveraging low 0.9 V VF for forward conduction during negative excursions. Use Value: Combined forward/reverse clamping action limits excursion to −0.9 V / +2.6 V, protecting downstream RF ICs rated for −0.3 V to 3.6 V absolute maximum ratings. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5221BS-7-F | Single Zener (2.4 V), SOT-363 package, 200 mW Ptot, no common-anode dual configuration | Requires external pairing for dual-clamp function; lacks integrated common node | Select when only single-rail clamping is needed and board area allows discrete duplication |
| BZX84-C2V4 | Single Zener (2.4 V), SOT-23 package, 350 mW Ptot, no dual-diode structure | Cannot provide simultaneous dual-path regulation or bidirectional clamping from one footprint | Choose for cost-sensitive, single-channel applications where layout density is less constrained |
Compared with MMBZ5221BS-7-F and BZX84-C2V4, the BZB984-C2V4,115 uniquely delivers matched dual-Zener regulation in a single SOT663 footprint, reducing component count by 50% and eliminating inter-device VZ mismatch-critical for precision differential clamping and rail-to-rail reference generation.

FAQ
What is the maximum continuous reverse current the BZB984-C2V4,115 can sustain at 25 °C?
The device does not specify a maximum continuous reverse current (IZ) rating; instead, it defines limiting values based on power dissipation. At 25 °C ambient and 2-diode loading on FR4 PCB, the 425 mW total power limit corresponds to ≤177 mA continuous IZ for 2.4 V VZ (P = V × I). Derating is required above 25 °C per Rth(j-a) = 294 K/W.
Can the two Zener diodes in the BZB984-C2V4,115 be used independently with different reference voltages?
No - both diodes share the same nominal Zener voltage (2.4 V) and tolerance (±5%). The BZB984-C2V4,115 is a single-part-number variant with identical electrical characteristics for K1–CA and K2–CA paths, as confirmed in Table 8 of the datasheet. Independent voltage values require separate part numbers (e.g., BZB984-C2V4 + BZB984-C5V1).
Is the SOT663 package compatible with standard reflow soldering profiles?
Yes - Nexperia explicitly states reflow soldering is the only recommended method for SOT663. The package outline and solder land pattern in Figures 9–10 align with IPC-7351B medium density, and thermal profiles must comply with JEDEC J-STD-020 moisture sensitivity level (MSL) requirements, though MSL rating is not specified in this datasheet.
Does the BZB984-C2V4,115 meet AEC-Q200 or other automotive qualification standards?
No - the revision history (Section 13) explicitly states "Product changed to non-automotive qualification" in Rev. 3. The device is intended for industrial, consumer, and IoT applications only; it has not undergone stress testing per AEC-Q200, and its reliability data does not cover automotive temperature ranges or lifetime requirements.
