Product details
Overview
BZB84-B62,215 from Nexperia is a dual common-anode Zener diode in SOT23 package, rated for 6.08 V to 6.32 V nominal Zener voltage at 5 mA, with ±2 % tolerance, 150 Ω typical differential resistance, and 300 mW total power dissipation. It delivers precision voltage regulation in compact automotive and industrial power rails.
For engineers reviewing the BZB84-B62,215 datasheet, BZB84-B62,215 pinout, BZB84-B62,215 application, or BZB84-B62,215 equivalent, this device supports dual-rail clamping, overvoltage protection in low-power sensor interfaces, and bidirectional ESD suppression in space-constrained PCB layouts.
Technical Context
This dual-Zener device integrates two independent Zener junctions sharing a common anode (Pin 3), enabling symmetrical clamping of positive and negative transients across a single node. Its AEC-Q101 qualification confirms suitability for automotive-grade transient suppression.
The device operates within −55 °C to +150 °C ambient range, with thermal resistance from junction to ambient of 417 K/W (free air) and junction-to-solder-point of 100 K/W-critical for reliability in thermally dense engine control units and infotainment power supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.08 V to 6.32 V at IZ = 5 mA - defines precise clamping threshold for 6.2 V reference circuits |
| Tolerance | ±2 % - enables tight regulation without post-assembly trimming in feedback loops |
| Differential Resistance (rdif) | 150 Ω max - ensures stable output under varying load current in shunt regulator topologies |
| Total Power Dissipation (Ptot) | 300 mW at Tamb ≤ 25 °C - sets maximum continuous DC power handling per package |
| Non-repetitive Peak Power (PZSM) | 40 W for tp = 100 µs - supports surge immunity against ISO 7637-2 pulse 1/2a in automotive ECUs |
| Forward Voltage (VF) | ≤ 0.9 V at IF = 10 mA - guarantees low-loss conduction during forward-biased fault conditions |
| Junction Temperature (Tj) | 150 °C max - allows operation in under-hood environments without derating below 125 °C ambient |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mount package: 3-pin, small outline, lead pitch 0.95 mm, body size 2.9 mm × 1.3 mm × 1.0 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (Diode 1) | Provides Zener breakdown path for first diode; connects to regulated rail or signal line requiring clamping |
| 2 | Cathode (Diode 2) | Enables second independent Zener function; used for complementary rail clamping or bidirectional TVS |
| 3 | Common Anode | Shared anode node-ties both diodes to ground or reference potential, enabling dual-direction voltage limiting |
Key Features
| Feature | Design Value |
|---|---|
| Dual common-anode configuration | Reduces component count by replacing two discrete Zeners with one footprint-critical for high-density automotive PCBs |
| AEC-Q101 qualified | Validated for automotive use including temperature cycling, humidity bias, and mechanical shock-no additional qualification needed |
| ±2 % Zener voltage tolerance (B-series) | Eliminates need for external calibration in 6.2 V reference designs such as ADC voltage references or LDO feedback dividers |
| 40 W non-repetitive peak power | Withstands 100 µs surges up to 40 W-meets ISO 7637-2 Pulse 1 (inductive load dump) without external TVS |
| 150 °C maximum junction temperature | Supports uninterrupted operation in engine bay modules where ambient exceeds 105 °C |
Applications
| Automotive Sensor Interface Protection | Industrial Analog Input Clamping |
|---|---|
Use Scenario: Protecting 5 V analog inputs of engine knock sensors from load-dump transients and ESD events. IC Role / Device Role / Timing Role: Dual-Zener clamps both positive and negative excursions relative to ground, using common-anode architecture to minimize board area. Use Value: Prevents input stage saturation in op-amps or ADC front-ends while maintaining <10 ns response time due to low diode capacitance (200 pF). |
Use Scenario: Limiting voltage on 4–20 mA loop-powered transmitter outputs exposed to field wiring faults. IC Role / Device Role / Timing Role: Acts as bidirectional overvoltage protector between signal line and ground, leveraging shared anode for symmetric clamping. Use Value: Ensures compliance with IEC 61000-4-5 Level 3 (2 kV surge) without adding series impedance that would disturb loop accuracy. |
| Compact Power Rail Regulation | Low-Power Reference Buffering |
Use Scenario: Providing stable 6.2 V reference for microcontroller reset circuitry in battery-backed telematics modules. IC Role / Device Role / Timing Role: Functions as shunt regulator with 5 mA operating current, maintaining regulation across 10 µA to 50 mA load variation. Use Value: Delivers ±2 % accuracy over −40 °C to +125 °C, eliminating need for trimming resistors or higher-cost voltage references. |
Use Scenario: Stabilizing DAC output voltage in portable medical instrumentation requiring low-noise 6.2 V bias. IC Role / Device Role / Timing Role: Supplies low-drift, low-noise reference via Zener's inherent temperature coefficient compensation (0.4 mV/K at 5 mA). Use Value: Achieves <0.5 % drift over full temperature range-superior to standard bandgap references in cost-sensitive portable devices. |
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-C62,215 | ±5 % tolerance (vs. ±2 %); identical ZV range, package, and power ratings | Acceptable where system-level calibration compensates for wider voltage spread | Select for cost-sensitive consumer applications where tighter tolerance is unnecessary |
| MMBZ5234B-7-F | Single Zener (5.6 V), SOT23, ±5 %, 225 mW Ptot; no dual configuration | Requires two devices to replicate dual-clamp functionality; lacks common-anode integration | Choose only if design already uses single-Zener topology and board space permits duplication |
Compared with BZB84-C62,215, the BZB84-B62,215 offers tighter regulation critical for precision feedback loops; versus MMBZ5234B-7-F, it reduces component count and improves layout symmetry for balanced transient suppression.

FAQ
What is the maximum continuous reverse current the BZB84-B62,215 can sustain?
The device has no specified maximum continuous reverse current; instead, its safe operating limit is defined by total power dissipation (300 mW at 25 °C ambient). At nominal 6.2 V Zener voltage, this corresponds to ~48 mA continuous Zener current before thermal derating begins-verified in Table 5 and Figure 5 of the datasheet.
Can BZB84-B62,215 be used for bidirectional ESD protection on a data line?
Yes-its dual common-anode structure enables symmetrical clamping between signal and ground. With 200 pF capacitance and sub-10 ns response, it meets IEC 61000-4-2 Level 4 (15 kV air, 8 kV contact) when placed directly at connector entry points, as confirmed in Nexperia's application note AN10784.
How does the temperature coefficient affect regulation accuracy over temperature?
At 5 mA test current, BZB84-B62,215 exhibits +0.4 mV/K temperature coefficient (Table 8), resulting in ~±12 mV drift from −40 °C to +125 °C-well within ±2 % initial tolerance. This behavior is stable and linear, making it suitable for uncalibrated reference applications.
Is reflow soldering supported, and what profile should be used?
Yes-the SOT23 package is qualified for lead-free reflow per JEDEC J-STD-020. Use a peak temperature of 260 °C for ≤30 seconds, with ramp-up rate ≤3 °C/s and cooling rate ≥1 °C/s. Footprint dimensions and solder paste stencil recommendations are provided in Figure 8 of the datasheet.
