Product details
Overview
BZB84-B13-QR from Nexperia is a dual Zener diode in SOT23 package with common anode configuration, rated for 13 V nominal working voltage (±2 % tolerance), 300 mW total power dissipation, and AEC-Q101 qualification for automotive voltage regulation. It provides dual-channel precision clamping in compact surface-mount form for space-constrained power rail protection.
For engineers reviewing the BZB84-B13-QR datasheet, BZB84-B13-QR pinout, BZB84-B13-QR application, or BZB84-B13-QR equivalent, this page delivers verified Zener voltage, thermal resistance, differential resistance, reverse current, and dual-diode terminal mapping - all confirmed from Nexperia's official Rev. 2 product data sheet dated 10 April 2024.
Technical Context
This dual Zener diode integrates two independent 13 V Zener elements sharing a common anode (Pin 3), enabling simultaneous voltage reference or overvoltage clamping on two separate signal or supply lines. Its ±2 % tolerance (B-series) ensures tight regulation stability across temperature and load variations.
Designed for automotive-grade reliability, it supports non-repetitive surge handling up to 40 W (100 µs square wave) and operates continuously at junction temperatures up to 150 °C. Thermal resistance from junction to solder point is 100 K/W, facilitating effective heat transfer in PCB-mounted applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 12.7 V to 13.3 V at IZ = 5 mA - defines precise clamping threshold for dual-rail protection |
| Differential Resistance rdif | 170 Ω max at IZ = 5 mA - determines regulation stiffness and output impedance under dynamic load |
| Reverse Current IR | 0.1 µA max at VR = 10.4 V - ensures low leakage during standby or pre-breakdown conditions |
| Total Power Dissipation Ptot | 300 mW at Tamb ≤ 25 °C - sets maximum continuous DC power handling on standard FR4 PCB |
| Non-repetitive Peak Power PZSM | 40 W for tp = 100 µs - enables transient surge suppression without device failure |
| Junction Temperature Tj | 150 °C maximum - supports operation in under-hood automotive environments |
| Thermal Resistance Rth(j-sp) | 100 K/W - quantifies thermal path efficiency from die to PCB solder joint |
Pinout & Package
SOT23 plastic surface-mount package (2.9 mm × 1.3 mm × 1.0 mm body, 1.9 mm pin pitch) with gull-wing leads and standardized footprint per Nexperia's Fig. 12 and Fig. 13.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (Diode 1) | Active clamping node for first Zener element; connects to protected line requiring 13 V reference |
| 2 | Cathode (Diode 2) | Independent clamping node for second Zener element; enables dual-rail or redundancy use |
| 3 | Common Anode | Shared return path for both Zeners; ties to system ground or regulated supply rail |
Key Features
| Feature | Design Value |
|---|---|
| Dual Zener architecture | Two independent 13 V ±2 % Zener elements in single SOT23 - reduces board area vs. discrete dual-diode solutions |
| AEC-Q101 qualification | Stress-tested per automotive discrete semiconductor standard - validated for engine control, body electronics, and ADAS modules |
| Low thermal resistance | Rth(j-sp) = 100 K/W - enables reliable power dissipation without heatsinking in high-temperature ambient |
| Tight voltage tolerance | ±2 % (B-series) - eliminates need for post-production trimming in precision reference designs |
| High surge robustness | 40 W non-repetitive peak power (100 µs) - withstands ISO 7637-2 pulse 1/2/5a transients in 12 V vehicle systems |

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 |
|---|---|---|---|
| ON Semiconductor NZX13B | Single Zener in DO-35 package; no dual configuration or common-anode topology | Requires two devices and additional layout area for dual-rail use; lacks AEC-Q101 rating | Select only when discrete placement and through-hole assembly are mandatory |
| Vishay BZX84-C13 | Single Zener in SOT23; ±5 % tolerance (C-series); no dual-element integration | Higher voltage variation (12.4–14.1 V) impacts reference accuracy; not AEC-Q101 qualified | Acceptable for cost-sensitive consumer applications where dual functionality and automotive grade are unnecessary |

FAQ
What is the exact Zener voltage range for BZB84-B13-QR at 5 mA test current?
The confirmed Zener voltage range is 12.7 V to 13.3 V at IZ = 5 mA, per Table 8 of Nexperia's Rev. 2 datasheet. This ±2 % tolerance is measured under controlled 25 °C conditions and reflects the B-series precision grading.
Can BZB84-B13-QR be used for bidirectional ESD protection?
No - it is a dual unidirectional Zener configuration with common anode; each cathode conducts only in reverse breakdown. For bidirectional protection, external series diodes or dedicated TVS arrays are required. Its primary function is regulated clamping, not symmetrical surge diversion.
How does thermal resistance differ between junction-to-ambient and junction-to-solder-point?
Rth(j-a) is 417 K/W in free air, while Rth(j-sp) is 100 K/W - the latter reflects direct conduction to PCB copper via pins 1 and 2. This 4.17× improvement confirms that proper PCB copper pour and solder joint quality dominate thermal performance in real layouts.
Is the marking code for BZB84-B13-QR publicly documented?
Yes - per Table 4, the marking code is "VV%". This three-character laser mark appears on the top surface of the SOT23 package and uniquely identifies the B-series 13 V variant within the BZB84-Q family.
