Product details
Overview
BZB84-B7V5,215 from Nexperia is a dual common-anode Zener diode in SOT23 package, designed for precision voltage regulation and transient suppression in compact power rails. It delivers 7.35 V to 7.65 V nominal Zener voltage at 5 mA, ≤80 Ω differential resistance, ≤15 µA reverse current at 5.3 V, and AEC-Q101 qualification for automotive environments.
For engineers reviewing the BZB84-B7V5,215 datasheet, BZB84-B7V5,215 pinout, BZB84-B7V5,215 application, or BZB84-B7V5,215 equivalent, this device supports dual-rail clamping, overvoltage protection in infotainment power supplies, and bidirectional ESD mitigation in CAN transceiver interfaces - with verified thermal resistance (Rth(j-a) = 417 K/W) and non-repetitive surge capability (40 W, 100 µs).
Technical Context
This dual-Zener uses a common-anode configuration enabling independent cathode control for bidirectional clamping or complementary reference generation. Each diode operates with ±2 % tolerance, 150 °C maximum junction temperature, and is characterized under IEC 60134 absolute maximum ratings.
Its 7.5 V nominal working voltage falls in the positive temperature coefficient range (+2.5 to +5.3 mV/K), ensuring stable regulation across automotive ambient ranges (−40 °C to +125 °C). The SOT23 footprint supports high-density PCB layouts while maintaining 300 mW total power dissipation at Tamb ≤25 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 7.35 V to 7.65 V at IZ = 5 mA - tight ±2 % tolerance enables accurate rail clamping without external trimming |
| Differential Resistance (rdif) | ≤80 Ω - low impedance ensures minimal voltage shift under load variation in feedback paths |
| Reverse Current (IR) | ≤1 µA at VR = 5.3 V - guarantees low leakage in standby power domains |
| Non-repetitive Peak Power (PZSM) | 40 W (100 µs square wave) - supports robust transient suppression per diode in ISO 7637-2 pulse 1/2a events |
| Total Power Dissipation (Ptot) | 300 mW at Tamb ≤25 °C - defines continuous DC regulation capability in thermally constrained SMT designs |
| Junction Temperature (Tj) | −55 °C to +150 °C - validated operation across full automotive under-hood thermal envelope |
| AEC-Q101 Qualified | Yes - certified for automotive-grade reliability including HTOL, temperature cycling, and ESD (HBM ≥2 kV) |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mount package: 3-pin, 1.3 mm × 2.9 mm footprint, 1.1 mm height, tin-plated leads compatible with standard reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (Diode 1) | Connects to regulated node requiring 7.5 V clamping; reverse-biased during overvoltage events |
| 2 | Cathode (Diode 2) | Independent cathode for second rail or bidirectional signal line protection (e.g., RS-485 bus) |
| 3 | Common Anode | Reference return path; ties both Zeners to system ground or negative rail for dual-polarity operation |
Key Features
| Feature | Design Value |
|---|---|
| Dual common-anode topology | Enables single-package bidirectional clamping or dual independent references without shared cathodes |
| ±2 % Zener voltage tolerance (B-series) | Reduces need for post-assembly calibration in 12 V automotive subsystems like body control modules |
| AEC-Q101 qualification | Validates suitability for front-end power management in ADAS camera ECUs and gateway controllers |
| 40 W non-repetitive surge rating | Withstands ISO 7637-2 Pulse 1 (inductive load dump) without derating in 24 V commercial vehicle systems |
| Low 150 pF capacitance at 0 V | Preserves signal integrity on high-speed lines (e.g., LIN bus) when used as ESD clamp |
Applications
| Automotive Power Rail Clamping | CAN Transceiver Protection |
|---|---|
Use Scenario: 12 V battery-supplied infotainment head unit exposed to load dump transients up to 35 V. IC Role / Device Role / Timing Role: Dual-Zener clamps both VCC and reset line simultaneously using common anode tied to ground.

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 |
|---|---|---|---|
| MMBZ5233BS-7-F | Single Zener, 6.2 V, SOT363, ±5 % tolerance, 200 mW Ptot | Requires two devices for dual-rail use; lacks common-anode integration | Select when board space allows discrete placement and ±5 % tolerance suffices |
| BZX84-C7V5 | Single Zener, 7.5 V, SOT23, ±5 % tolerance, 300 mW Ptot, no dual configuration | Cannot perform simultaneous bidirectional clamping or dual-reference generation | Choose only for cost-sensitive single-rail applications where dual functionality is unnecessary |
Compared with MMBZ5233BS-7-F and BZX84-C7V5, BZB84-B7V5,215 uniquely integrates two ±2 % Zeners in one SOT23 with shared anode - reducing component count by 50 %, improving thermal coupling between diodes, and enabling true symmetrical clamping critical in automotive CAN and LIN networks.

FAQ
What is the maximum continuous forward current for BZB84-B7V5,215?
The absolute maximum forward current is 200 mA per diode, specified under IEC 60134 limiting values. This rating applies at Tamb ≤25 °C with FR4 PCB mounting (single-sided copper, tin-plated). Derating is required above 25 °C ambient, following the Rth(j-a) = 417 K/W thermal resistance curve.
Can BZB84-B7V5,215 be used for bidirectional ESD protection on a differential pair?
Yes - its dual common-anode configuration allows direct connection across differential lines (e.g., CANH–CANL), with each cathode tied to one line and the anode grounded. This provides symmetrical ±7.5 V clamping with matched dynamic impedance, validated for IEC 61000-4-2 Level 4 (±8 kV contact) when combined with series impedance.
How does the temperature coefficient affect regulation accuracy over automotive temperature ranges?
At 7.5 V nominal, the temperature coefficient is +2.5 to +5.3 mV/K. Over −40 °C to +125 °C, this results in a total VZ shift of approximately ±0.8 V - well within the ±2 % initial tolerance band. The monolithic dual-die structure ensures matched drift between both Zeners, preserving balance in differential applications.
Is the SOT23 package lead-free and RoHS compliant?
Yes - BZB84-B7V5,215 is manufactured with lead-free terminations and complies with EU RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. The device uses SnAgCu solder-compatible finishes and meets JEDEC J-STD-020 moisture sensitivity level 1 (MSL1) for unlimited floor life at ≤30 °C/60 % RH.
