Product details
Overview
BZB84-C9V1,215 from Nexperia is a dual common-anode Zener diode in SOT23 package, rated for 9.1 V nominal Zener voltage (±5 % tolerance), 300 mW total power dissipation, and 40 W non-repetitive peak reverse power. It serves voltage regulation and overvoltage protection functions in automotive power rails and industrial sensor interfaces.
For engineers reviewing the BZB84-C9V1,215 datasheet, BZB84-C9V1,215 pinout, BZB84-C9V1,215 application, or BZB84-C9V1,215 equivalent, this page delivers verified Zener voltage range (8.5–9.6 V), differential resistance (100 Ω max at IZ = 5 mA), temperature coefficient (+3.8 to +7.0 mV/K), reverse current (0.5 µA max at VR = 7.3 V), and AEC-Q101 qualification status - all critical for automotive-grade design validation.
Technical Context
This dual-Zener device integrates two independent Zener junctions sharing a common anode (Pin 3), enabling bidirectional clamping or dual-rail regulation from a single footprint. Its SOT23 package supports surface-mount assembly with thermal resistance of 417 K/W (junction-to-ambient) and 100 K/W (junction-to-solder point).
Designed for stable operation across −55 °C to +150 °C ambient, it features low capacitance (150 pF max at 1 MHz), tight voltage tolerance (±5 %), and robust surge capability (3.0 A non-repetitive peak reverse current at 100 µs pulse). The device meets AEC-Q101 stress test requirements for automotive discrete semiconductors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 8.5–9.6 V at IZ = 5 mA; defines precise clamping threshold for 9.1 V nominal rail protection |
| Differential Resistance (rdif) | ≤100 Ω at IZ = 5 mA; ensures minimal voltage shift under load variation |
| Reverse Current (IR) | ≤0.5 µA at VR = 7.3 V; guarantees low leakage in standby regulation |
| Temperature Coefficient (SZ) | +3.8 to +7.0 mV/K; enables predictable voltage drift compensation in wide-temp environments |
| Total Power Dissipation (Ptot) | 300 mW at Tamb ≤ 25 °C; sets continuous thermal limit for PCB layout planning |
| Non-repetitive Peak Reverse Power (PZSM) | 40 W at tp = 100 µs; supports transient suppression of ESD or load-dump events |
| Junction Temperature (Tj) | 150 °C maximum; defines absolute thermal ceiling for reliability margining |
Pinout & Package

| 2 | Cathode (Diode 2) | Enables independent clamping on second rail or bidirectional voltage limiting |
| 3 | Common Anode | Shared return path; simplifies routing and reduces PCB area vs. two discrete Zeners |
Key Features
| Feature | Design Value |

Applications
| Automotive Power Rail Protection | Industrial Sensor Signal Conditioning |
|---|---|
Use Scenario: Clamping 12 V battery-supplied microcontroller I/O lines against load dump transients. IC Role / Device Role / Timing Role: Dual-Zener acts as bidirectional overvoltage clamp referenced to common anode ground. Use Value: 40 W peak power handling and 3.0 A surge current suppress 100 µs transients without degradation. |
Use Scenario: Regulating excitation voltage for 4–20 mA current-loop pressure sensors. IC Role / Device Role / Timing Role: Provides stable 9.1 V reference via Zener breakdown, decoupled from supply ripple. Use Value: ±5 % tolerance and +3.8 to +7.0 mV/K temperature coefficient enable <1 % total error over −40 to +125 °C. |
| Consumer USB Port ESD Protection | Medical Diagnostic Equipment Power Sequencing |
Use Scenario: Protecting USB data lines (D+/D−) from IEC 61000-4-2 contact discharge. IC Role / Device Role / Timing Role: Common-anode dual Zener shunts positive/negative ESD pulses to ground simultaneously.

Use Scenario: Enabling controlled power-up sequencing of analog front-end and digital subsystems. IC Role / Device Role / Timing Role: Zener diode holds reset line low until 9.1 V rail stabilizes, then releases reset. Use Value: 0.5 µA reverse current prevents premature reset release during slow-ramp power supplies. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZB84-B9V1,215 | ±2 % Zener tolerance (vs. ±5 %); higher cost; tighter VZ spread (8.92–9.28 V) | Better suited for precision reference where <1 % total error is required | Select when voltage accuracy outweighs cost sensitivity in high-reliability systems |
| MMBZ5240BLT1G | Single Zener (9.1 V, ±5 %); SOT23 package; 225 mW Ptot; no dual configuration | Requires two devices for bidirectional clamping; increases board area and BOM count | Choose only if dual functionality is unnecessary and legacy compatibility is mandatory |
Compared with BZB84-C9V1,215, the BZB84-B9V1,215 offers superior voltage accuracy at higher cost, while MMBZ5240BLT1G lacks integrated dual topology - making the C-series optimal for cost-constrained automotive and industrial designs requiring compact bidirectional protection.

FAQ
What is the maximum allowable junction temperature for BZB84-C9V1,215?
The absolute maximum junction temperature is 150 °C, as defined in the Absolute Maximum Rating System (IEC 60134). Operation above this limit risks permanent parametric shift or catastrophic failure. Derating curves in the datasheet require power reduction above 25 °C ambient to maintain safe Tj.
How does the common-anode configuration affect circuit implementation?
The common-anode (Pin 3) forces both Zener cathodes (Pins 1 and 2) to be independently connected to separate nodes, enabling either bidirectional clamping (e.g., D+ and D− to ground) or dual-rail regulation (e.g., +9.1 V and −9.1 V references). It eliminates need for external node tying.
Is BZB84-C9V1,215 suitable for IEC 61000-4-2 ESD protection?
Yes - its 40 W non-repetitive peak reverse power rating at 100 µs pulse width and 3.0 A peak current aligns with Level 4 (8 kV contact, 15 kV air) ESD testing. Combined with 150 pF capacitance, it provides effective clamping without compromising USB 2.0 signal integrity.
What is the significance of the 'C' in BZB84-C9V1,215?
The 'C' denotes ±5 % Zener voltage tolerance per the E24 standard, distinguishing it from 'B' grade (±2 %). This tolerance band balances cost and performance for general-purpose regulation where tight voltage matching is not critical, such as bulk power rail clamping.
