Product details
Overview
BZB984-C13,115 from Nexperia is a dual Zener voltage regulator diode in SOT663 package with nominal 13 V working voltage (±5% tolerance), 50 Ω typical differential resistance at IZ = 5 mA, and 0.1 µA reverse current at VR = 10 V. It serves as a precision low-power reference or clamping element in space-constrained power rail monitoring circuits.
For engineers reviewing the BZB984-C13,115 datasheet, BZB984-C13,115 pinout, BZB984-C13,115 application, or BZB984-C13,115 equivalent, this device is selected for dual-cathode common-anode regulation where thermal coupling between diodes improves tracking stability and footprint efficiency in ESD-protected analog front-ends.
Technical Context
This double-Zener diode integrates two independent 13 V Zener elements sharing a common anode terminal, enabling symmetrical bidirectional clamping or dual-rail referencing without discrete pairing. Its 12.4 V to 14.1 V guaranteed VZ range at IZ = 5 mA ensures stable regulation under ±10% supply variation.
Thermal resistance from junction to solder point is 125 K/W (2 diodes loaded), supporting sustained operation up to 150 °C junction temperature. The 0.9 V forward voltage at 10 mA enables use as a low-drop series clamp in reverse-biased protection paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VZ (nominal) | 13 V - precise regulation point for 12–14 V system rails |
| VZ tolerance | ±5% - tight spread enables single-bin calibration in reference designs |
| rdif | 50 Ω max at IZ = 5 mA - low dynamic impedance maintains regulation accuracy under load transients |
| IR @ VR = 10 V | 0.1 µA max - minimal leakage preserves battery life in always-on sensing nodes |
| Ptot (2 diodes) | 425 mW - sufficient headroom for transient surge absorption per IEC 61000-4-2 Level 4 |
| Tj max | 150 °C - supports operation in automotive under-hood ambient up to +105 °C with derating |
Pinout & Package
Package: SOT663 - ultra-small flat plastic SMD package (1.7 × 1.5 × 0.5 mm) with exposed cathode tabs for enhanced thermal conduction on FR4 PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 | First Zener cathode - connects to regulated node requiring 13 V reference or clamping |
| 2 | K2 | Second Zener cathode - enables dual-rail referencing or mirrored protection path |
| 3 | CA | Common anode - tied to ground or low-impedance return path for both diodes |
Key Features
| Feature | Design Value |
|---|---|
| Dual Zener topology | Two matched 13 V Zeners share one anode, reducing board area by 40% vs discrete pair |
| Low thermal resistance | Rth(j-sp) = 125 K/W (2 diodes) - enables 2× higher continuous power vs standard SOD-323 dual diodes |
| ESD robustness | IEC 61000-4-2 Level 4 compliant (8 kV contact / 15 kV air) due to integrated clamping structure |
| Stable temperature coefficient | SZ = +8.8 mV/K - positive TC compensates for negative TC of downstream circuitry in precision references |
Applications
| Industrial Sensor Signal Conditioning | USB-C Port Overvoltage Protection |
|---|---|
Use Scenario: Protecting 12-bit ADC inputs in factory-floor temperature transmitters exposed to 4–20 mA loop surges. IC Role / Device Role / Timing Role: Dual-cathode Zener clamps both signal and reference rails to ±13 V while sharing ground return. Use Value: Eliminates need for separate TVS diodes and reduces BOM count by one component per channel. |
Use Scenario: Safeguarding USB-C CC line and VBUS detection circuitry against hot-plug induced transients. IC Role / Device Role / Timing Role: Common-anode configuration provides symmetrical clamping to GND for bidirectional CC signaling and unidirectional VBUS overvoltage limiting. Use Value: Achieves <1 ns response time with <0.5 pF inter-electrode capacitance, preserving USB-C 10 Gbps signal integrity. |
| Automotive Body Control Module Power Monitoring | Medical Wearable Battery Voltage Supervision |
Use Scenario: Monitoring 12 V battery rail in BCMs where space limits placement of discrete regulators near microcontroller reset pins. IC Role / Device Role / Timing Role: Provides 13 V Zener reference for comparator-based undervoltage lockout (UVLO) with thermal tracking between dual elements. Use Value: Matches temperature drift across both diodes, reducing UVLO threshold drift to <±0.5% over −40 °C to +105 °C. |
Use Scenario: Enabling low-power battery gauge ICs in patch-style ECG monitors with strict 2.5 mm² PCB area budget. IC Role / Device Role / Timing Role: Supplies stable 13 V reference for ADC full-scale calibration during periodic self-test cycles. Use Value: Draws only 0.1 µA leakage at 10 V, extending 300 mAh coin-cell runtime by >12 months versus standard Zener alternatives. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MMBZ5243B | Single 13 V Zener in SOT-23; no dual-cathode topology | Requires two devices for dual-rail use; 2× footprint and solder joints | Select when only single-rail clamping is needed and board space allows discrete layout |
| Vishay BZX84-C13 | Single Zener in SOT-23; 5% tolerance but no common-anode dual configuration | Cannot provide matched thermal tracking; higher part count for symmetrical protection | Choose for cost-sensitive consumer applications where dual-diode integration is unnecessary |
Compared with MMBZ5243B and BZX84-C13, the BZB984-C13,115 delivers integrated dual-cathode functionality in half the PCB area, tighter thermal coupling for drift-critical references, and lower assembly cost via single-placement operation - making it optimal for miniaturized industrial and medical systems.

FAQ
What is the maximum continuous reverse current the BZB984-C13,115 can sustain at 25 °C ambient?
The device supports up to 200 mA forward current (IF) but is rated for Zener operation at IZ = 5 mA nominal. Its absolute maximum non-repetitive peak reverse current (IZSM) is 8 A for 100 µs pulses. Continuous DC reverse current must remain below 5 mA to maintain regulation accuracy and avoid exceeding 425 mW total power dissipation with both diodes active.
Can the BZB984-C13,115 be used in avalanche mode for overvoltage protection?
No - the BZB984-C13,115 is specified and characterized exclusively as a Zener-regulated device operating in breakdown mode above 12.4 V. Its 13 V nominal VZ and controlled differential resistance (50 Ω max) confirm Zener-dominated behavior. Avalanche characteristics are not characterized or guaranteed; using it outside Zener region risks parametric shift or premature failure.
How does the common-anode configuration affect PCB layout for ESD protection?
The CA pin must be connected directly to the lowest-impedance ground plane with minimal trace length (<2 mm) and adjacent thermal vias to ensure effective transient current shunting. K1 and K2 should route separately to protected nodes (e.g., data lines or power rails), avoiding shared traces that could couple noise between channels. This layout preserves independent clamping action while maximizing thermal dissipation through the shared anode pad.
Is the BZB984-C13,115 qualified for automotive applications?
No - per Nexperia's revision history (Rev. 3, Dec 2022), the BZB984 series was explicitly changed to non-automotive qualification status. It lacks AEC-Q101 stress testing and is not warranted for automotive use. For automotive-grade dual Zeners, consider Nexperia's PTVSxP1UP series or Diodes Inc. DZ23 series with AEC-Q101 certification.
