Product details
Overview
BZB84-C75,215 from Nexperia is a dual common-anode Zener diode in SOT23 package, designed for precision voltage regulation and overvoltage protection in compact PCB layouts. It delivers 75 V nominal Zener voltage (±5 % tolerance), 500 Ω typical differential resistance at 2 mA, 0.05 µA reverse current at 56.3 V, and AEC-Q101 qualification for automotive power rail clamping.
For engineers reviewing the BZB84-C75,215 datasheet, BZB84-C75,215 pinout, BZB84-C75,215 application, or BZB84-C75,215 equivalent, this device supports dual-rail voltage reference generation, transient suppression in 12 V/24 V vehicle subsystems, and bidirectional ESD protection in space-constrained sensor interfaces.
Technical Context
This dual-Zener uses a common-anode configuration enabling independent cathode control for two discrete regulation paths in one footprint. Each diode exhibits a temperature coefficient of +52.5 mV/K at 2 mA and 75 V nominal breakdown, with junction-to-ambient thermal resistance of 417 K/W on FR4 PCB.
It operates across −55 °C to +150 °C ambient, supports non-repetitive peak reverse power dissipation up to 40 W (100 µs square wave), and maintains stable regulation under surge conditions per IEC 60134 limiting values.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 70.0 V to 79.0 V at IZ = 2 mA - defines precise clamping threshold for 75 V nominal rail protection |
| Differential Resistance (rdif) | 500 Ω max at IZ = 2 mA - ensures low dynamic impedance for stable regulation under load variation |
| Reverse Current (IR) | 0.05 µA max at VR = 56.3 V - guarantees minimal leakage in standby mode for battery-sensitive systems |
| Non-repetitive Peak Reverse Current (IZSM) | 0.20 A at tp = 100 µs - enables robust transient suppression without latch-up |
| Total Power Dissipation (Ptot) | 300 mW at Tamb ≤ 25 °C - sets continuous thermal limit for surface-mount reliability on standard FR4 |
| Junction Temperature (Tj) | 150 °C maximum - allows operation in under-hood automotive environments |
| AEC-Q101 Qualified | Yes - validated for automotive-grade reliability including temperature cycling and HTRB |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mounted package with 3 leads; 1.9 mm × 1.1 mm body, 0.9 mm height, and gull-wing lead form for reflow compatibility.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (Diode 1) | Provides regulated output node for first Zener path; connects to protected signal or supply rail |
| 2 | Cathode (Diode 2) | Independent regulated output node for second Zener path; enables dual-voltage referencing |
| 3 | Common Anode | Shared return path to ground or negative rail; simplifies layout and reduces component count |
Key Features
| Feature | Design Value |
|---|---|

Applications
| Automotive Body Control Module (BCM) | Industrial PLC Analog Input Protection |
|---|---|
Use Scenario: Protecting microcontroller ADC inputs from load-dump-induced overvoltage in door module circuits.

Use Value: Maintains <1 pF added capacitance per cathode, preserving >1 MHz signal bandwidth while passing IEC 61000-4-2 Level 4 (8 kV contact). |
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 |
|---|---|---|---|
| MMBZ5275B-7-F | Single Zener, 75 V ±5 %, SOT23, 200 mW Ptot, no dual configuration | Requires two devices for dual-rail use; higher board area and assembly cost | Select when only one regulation node is needed or legacy single-diode layout must be preserved |
| BZX84-C75 | Single Zener, 75 V ±5 %, SOT23, 300 mW Ptot, identical Zener specs but no dual functionality | Cannot provide simultaneous dual-cathode clamping; lacks common-anode convenience | Choose for cost-sensitive single-rail applications where dual functionality is unnecessary |
Compared with MMBZ5275B-7-F and BZX84-C75, BZB84-C75,215 uniquely integrates two independently controllable Zener paths in one SOT23, reducing component count by 50 % and eliminating inter-device matching variance in dual-reference designs.

FAQ
What is the maximum non-repetitive peak reverse power dissipation for BZB84-C75,215?
The BZB84-C75,215 supports 40 W non-repetitive peak reverse power dissipation under 100 µs square-wave pulse conditions at Tj = 25 °C, as defined in Table 5 of the Nexperia datasheet Rev. 03. This rating enables reliable handling of ISO 7637-2 load-dump transients without degradation.
How does the dual common-anode configuration affect circuit design?
The common-anode pin (Pin 3) serves as a shared reference node, allowing independent cathodes (Pins 1 and 2) to clamp two different signals or rails to the same ground or negative potential. This eliminates the need for separate anode routing and improves layout symmetry in differential or dual-supply protection schemes.
Is BZB84-C75,215 suitable for 24 V commercial vehicle applications?
Yes - its 75 V Zener range, AEC-Q101 qualification, −55 °C to +150 °C operating temperature, and 40 W surge capability meet ISO 16750-2 requirements for 24 V truck and bus electrical systems, including load-dump immunity up to 40 V sustained for 400 ms.
What is the typical differential resistance at 2 mA for this part?
Per Table 11 in the datasheet, the differential resistance (rdif) for BZB84-C75 is 500 Ω maximum at IZ = 2 mA and Tj = 25 °C. This value ensures predictable regulation slope and minimal output voltage shift under varying load currents in precision reference applications.
