Product details
Overview
BZB84-C62-QR from Nexperia is a dual Zener diode in SOT23 package with common-anode configuration, rated for 62 V nominal working voltage (±5 % 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-C62-QR datasheet, BZB84-C62-QR pinout, BZB84-C62-QR application, or BZB84-C62-QR equivalent, this page delivers verified Zener parameters, dual-diode terminal mapping, automotive-grade thermal limits, and real-world clamping use cases - all confirmed from Nexperia's Rev. 2 (April 2024) product data sheet.
Technical Context
This dual Zener operates with two independent cathodes (K1, K2) sharing a common anode (CA), enabling simultaneous regulation or bidirectional clamping on separate nets. Each diode supports 5 mA test current and exhibits 450 Ω typical differential resistance at that point.
The device features a positive temperature coefficient of +43.4 mV/K at 2 mA, ensuring stable voltage reference behavior across automotive ambient ranges (−55 °C to +150 °C), and sustains non-repetitive peak reverse current up to 0.3 A under 100 µs surge conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Zener Voltage | 62 V ±5 % - defines clamping threshold for overvoltage protection circuits |
| Total Power Dissipation | 300 mW - maximum continuous power handling on FR4 PCB with standard footprint |
| Differential Resistance | 450 Ω max at IZ = 2 mA - determines regulation stiffness and output impedance |
| Non-repetitive Peak Reverse Current | 0.3 A - surge current capability for transient suppression (tp = 100 µs) |
| Forward Voltage | 0.9 V max at IF = 10 mA - forward conduction drop during polarity-reversal events |
| Junction Temperature Range | −55 °C to +150 °C - validated operating envelope for under-hood automotive use |
| AEC-Q101 Qualified | Yes - certified for automotive discrete semiconductor stress testing per AEC standard |
Pinout & Package
SOT23 plastic surface-mount package (2.9 mm × 1.3 mm × 1.0 mm body, 1.9 mm pitch); thermally optimized for reflow soldering with Rth(j-sp) = 100 K/W to solder points.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 (cathode of diode 1) | Connects to regulated node requiring 62 V clamping; reverse-biased during operation |
| 2 | K2 (cathode of diode 2) | Independent cathode for second regulated path; enables dual-rail or redundancy schemes |
| 3 | CA (common anode) | Shared anode connection; ties both Zeners to system ground or negative reference rail |
Key Features
| Feature | Design Value |
|---|---|
| Dual common-anode topology | Enables compact dual-voltage clamping without discrete anode routing or extra passives |
| ±5 % Zener tolerance (C-series) | Meets cost-sensitive automotive subsystem requirements where tight regulation is secondary to robustness |
| 40 W non-repetitive peak power rating | Supports ISO 7637-2 pulse 1/2/5a transient suppression without external TVS stacking |
| AEC-Q101 qualification | Validated for 15-year automotive service life under thermal cycling, humidity, and mechanical stress |
| Low 0.05 µA reverse leakage at VR = 49.6 V | Minimizes standby current drain in always-on vehicle modules (e.g., CAN wake-up circuits) |
Applications
| Automotive Body Control Module (BCM) | Infotainment Power Sequencing |

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 NZX62C | Single Zener, DO-35 through-hole, ±5 %, 500 mW Ptot | Lacks dual-cathode topology; requires two devices and larger board area | Select when legacy through-hole assembly or higher power margin is required |
| Vishay BZX84-C62 | Single Zener, SOT23, ±5 %, 300 mW Ptot, no AEC-Q101 qualification | Not automotive-qualified; lower surge reliability in harsh environments | Select only for non-automotive industrial applications with identical voltage needs |
Compared with BZB84-C62-QR, NZX62C offers higher power but lacks integration and automotive qualification, while BZX84-C62 matches form factor and voltage but omits AEC-Q101 validation and dual-diode functionality - making BZB84-C62-QR the sole choice for space-constrained, safety-critical dual-clamp automotive designs.

FAQ
What is the maximum allowable junction temperature for continuous operation?
The absolute maximum junction temperature is 150 °C, validated per IEC 60134 limiting values. Operation above this threshold causes permanent degradation. Derating is required above 25 °C ambient: total power dissipation reduces linearly to zero at 150 °C junction, based on Rth(j-a) = 417 K/W.
Can BZB84-C62-QR be used for bidirectional ESD protection?
No - it is a unidirectional Zener clamp with common-anode configuration. For bidirectional ESD protection, a dedicated TVS array like Nexperia PESD5V0S1BA is required. BZB84-C62-QR clamps only in reverse bias (cathode-to-anode) and conducts forward at ~0.9 V, unsuitable for AC signal line protection.
How does the C-tolerance grade affect regulation accuracy in real circuits?
The ±5 % tolerance means actual Zener voltage falls between 58.9 V and 65.1 V at 2 mA. In practice, this impacts precision reference applications - e.g., feedback divider design must accommodate this 6.2 V window. For tighter regulation, select B-grade (±2 %) variants like BZB84-B62-QR.
Is the marking code 'PQ%' unique to BZB84-C62-QR?
Yes - per Table 4 of the datasheet, 'PQ%' is the exclusive top-side marking for BZB84-C62-QR. This laser-marked code enables traceability and distinguishes it from other C-series voltages (e.g., 'PR%' for C68-QR) and B-series equivalents (e.g., 'RG%' for B62-QR).
