Product details
Overview
BZB84-C22,215 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 nominal 22 V Zener voltage (20.8–23.3 V), ±5 % tolerance, 250 Ω differential resistance at 5 mA, 1.25 A non-repetitive peak reverse current, and 300 mW total power dissipation - used in automotive body control modules for ECU reference stabilization.
For engineers reviewing the BZB84-C22,215 datasheet, BZB84-C22,215 pinout, BZB84-C22,215 application, or BZB84-C22,215 equivalent, key selection criteria include Zener voltage tolerance, dual-diode common-anode topology, AEC-Q101 qualification, thermal resistance (Rth(j-a) = 417 K/W), and SOT23 surface-mount compatibility with reflow soldering.
Technical Context
This dual Zener diode integrates two independent Zener junctions sharing a common anode (Pin 3), enabling bidirectional clamping or dual-rail regulation from a single footprint. Its design supports low-impedance voltage references with tight 20.8–23.3 V working range and temperature coefficient of +15.4 to +20.0 mV/K at IZ = 5 mA.
The device operates across −55 °C to +150 °C ambient, with junction temperature limited to 150 °C, and meets AEC-Q101 stress requirements for automotive under-hood applications. Pulse handling is defined for 100 µs square-wave surges up to 40 W per diode.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 20.8 V to 23.3 V at IZ = 5 mA - defines stable regulation window for 22 V nominal rail |
| Tolerance | ±5 % - matches C-series grading for cost-sensitive automotive and industrial designs |
| Differential Resistance (rdif) | 250 Ω max at IZ = 5 mA - ensures low dynamic impedance for stable reference under load variation |
| Non-repetitive Peak Reverse Current (IZSM) | 1.25 A at tp = 100 µs - enables transient surge suppression without latch-up |
| Total Power Dissipation (Ptot) | 300 mW at Tamb ≤ 25 °C - sets thermal derating baseline for PCB layout and copper area planning |
| Forward Voltage (VF) | ≤ 0.9 V at IF = 10 mA - confirms low-loss forward conduction for clamp-assist or polarity protection roles |
| Thermal Resistance (Rth(j-a)) | 417 K/W - quantifies self-heating on standard FR4 PCB, guiding thermal pad design and airflow needs |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mount package: 3-pin, small-outline transistor outline with gull-wing leads; 1.3 mm × 2.9 mm footprint, 1.1 mm height; optimized for automated placement and reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (Diode 1) | Primary Zener output node for 22 V regulation path; connects to protected rail or reference point |
| 2 | Cathode (Diode 2) | Secondary Zener output node - enables dual-rail clamping or redundancy in safety-critical circuits |
| 3 | Common Anode | Shared return path; ties both Zeners to ground or negative supply - simplifies routing and reduces component count |
Key Features
| Feature | Design Value |
|---|---|
| Dual common-anode configuration | Enables bidirectional voltage clamping or dual independent 22 V references from one SOT23 footprint |
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD (HBM ≥ 8 kV) |
| ±5 % Zener tolerance (C-series) | Reduces BOM complexity vs. tighter-tolerance variants while maintaining functional margin in 12 V/24 V systems |
| 40 W non-repetitive peak power rating | Supports ISO 7637-2 pulse 1/2/5a surge suppression without external TVS stacking |
| Wide operating temperature range | −55 °C to +150 °C ambient operation - suitable for engine bay, transmission control, and ADAS sensor modules |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |

FAQ
What is the maximum continuous reverse current for BZB84-C22,215 at 25 °C?
The device does not specify a continuous reverse current rating; instead, its DC operation is governed by total power dissipation (300 mW max at Tamb ≤ 25 °C). At nominal 22 V, this limits steady-state Zener current to approximately 13.6 mA - exceeding typical reference applications but requiring thermal derating above ambient.
Can BZB84-C22,215 be used for bidirectional ESD protection?
Yes - its dual-cathode/common-anode structure allows symmetrical clamping between either cathode and the shared anode. With 8 kV HBM ESD rating and 1.25 A peak surge capability, it protects data lines like LIN or SENT interfaces against contact discharge per IEC 61000-4-2, provided layout minimizes trace inductance.
How does temperature affect the Zener voltage of BZB84-C22,215?
At IZ = 5 mA, the temperature coefficient ranges from +15.4 to +20.0 mV/K - meaning VZ increases ~0.33–0.44 V over a 22 °C rise. This positive drift is typical for Zeners above 5.6 V and must be compensated in high-accuracy references via external trimming or digital calibration.
Is the SOT23 footprint compatible with standard reflow profiles?
Yes - Nexperia specifies compatibility with JEDEC J-STD-020D reflow profiles. The SOT23 outline uses 0.6 mm solder land width (3×), 0.5 mm pitch, and requires peak temperatures ≤260 °C for ≤30 seconds. Thermal resistance data assumes standard FR4 PCB with single-sided 1 oz copper and tin plating.
