Product details
Overview
BZB84-C20,215 from Nexperia is a dual common-anode Zener diode in SOT23 package, rated for 20 V nominal Zener voltage (18.8–21.2 V), ±5 % tolerance, 300 mW total power dissipation, and 40 W non-repetitive peak reverse power. It serves voltage regulation and overvoltage protection in automotive body control modules and industrial sensor signal conditioning circuits.
For engineers reviewing the BZB84-C20,215 datasheet, BZB84-C20,215 pinout, BZB84-C20,215 application, or BZB84-C20,215 equivalent, this page delivers verified electrical specs, thermal behavior, AEC-Q101 qualification status, dual-diode configuration implications, and real-world use context for board-level design validation.
Technical Context
This dual Zener diode integrates two independent 20 V Zener elements sharing a common anode (Pin 3), enabling bidirectional clamping or complementary reference generation in compact space-constrained layouts. Its differential resistance is ≤225 Ω at IZ = 5 mA, and temperature coefficient is +14.0 to +18.0 mV/K - indicating positive drift above ~6.2 V nominal, critical for precision biasing stability.
Designed per IEC 60134 absolute maximum ratings, it supports 200 mA forward current and withstands 1.5 A non-repetitive peak reverse current (tp = 100 µs). Thermal resistance from junction to ambient is 417 K/W on FR4 PCB, limiting continuous dissipation without derating above Tamb = 25 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 18.8 V to 21.2 V at IZ = 5 mA - defines clamping threshold with ±5 % tolerance for stable reference generation |
| Total Power Dissipation (Ptot) | 300 mW at Tamb ≤ 25 °C - sets maximum steady-state thermal load before derating begins |
| Non-repetitive Peak Reverse Power (PZSM) | 40 W for tp ≤ 100 µs - enables transient surge suppression in ESD or load-dump events |
| Differential Resistance (rdif) | ≤225 Ω at IZ = 5 mA - determines output impedance and regulation sensitivity to current variation |
| Reverse Current (IR) | ≤0.05 µA at VR = 15 V - ensures minimal leakage in high-impedance bias networks |
| Forward Voltage (VF) | ≤0.9 V at IF = 10 mA - defines conduction loss when used as forward-biased clamp or level shifter |
| Junction Temperature (Tj) | −55 °C to +150 °C - supports operation in under-hood automotive environments and industrial enclosures |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mount package: 3-pin, small outline, standard footprint compatible with reflow and wave soldering per Nexperia's recommended land patterns.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (Diode 1) | Provides Zener breakdown path for first diode; connects to regulated node or signal line requiring clamping |
| 2 | Cathode (Diode 2) | Enables independent second clamping path; allows dual-rail protection or split-supply reference |
| 3 | Common Anode | Shared return node; simplifies PCB routing and enables bidirectional voltage limiting across two signals |
Key Features
| Feature | Design Value |
|---|---|
| Dual common-anode configuration | Reduces component count and board area vs. two discrete Zeners; enables symmetrical clamping on differential signals |
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, humidity, and mechanical shock - suitable for BCM, lighting, and ADAS subsystems |
| ±5 % Zener tolerance (C-series) | Meets cost-sensitive industrial applications where tight regulation is secondary to robustness and supply chain stability |
| 417 K/W junction-to-ambient thermal resistance | Defines thermal derating slope: Ptot drops linearly to zero at ~100 °C ambient on standard FR4 - informs heatsinking decisions |
| 1.5 A non-repetitive peak reverse current | Supports IEC 61000-4-2 Level 4 ESD protection (±15 kV air/±8 kV contact) when combined with series impedance |
Applications
| Automotive Body Control Module (BCM) | Industrial Sensor Signal Conditioning |
|---|---|

IC Role / Device Role / Timing Role: Common-anode dual Zener shunting reverse polarity and flyback energy into shared return path. Use Value: Eliminates need for separate TVS diodes per channel, reducing BOM cost by 35 % in 16-channel DIN-rail I/O modules. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5243B-7-F (Diodes Inc.) | Single Zener, 12 V, ±5 %, SOT23; no dual configuration or common anode | Requires two devices for dual-clamp function; higher assembly cost and layout area | Select only if single-rail clamping suffices and common-anode topology is unnecessary |
| BZX84-C20 (Nexperia) | Single Zener, same 20 V rating and ±5 % tolerance, identical SOT23 package | Lacks second cathode; cannot perform bidirectional or differential clamping without external wiring | Choose when space permits discrete placement or when only one clamping path is required |
Compared with MMBZ5243B-7-F and BZX84-C20, BZB84-C20,215 uniquely delivers dual 20 V Zener functions in one SOT23 footprint with shared anode - reducing component count, improving thermal coupling between diodes, and enabling true differential voltage limiting essential in noise-immune industrial interfaces.

FAQ
What is the maximum continuous reverse current the BZB84-C20,215 can handle at 25 °C ambient?
The device has no specified maximum continuous reverse current; its steady-state limit is governed by total power dissipation (300 mW at Tamb ≤ 25 °C). At 20 V Zener voltage, this corresponds to ≤15 mA average reverse current before thermal derating applies. Exceeding this requires ambient temperature reduction per the 417 K/W thermal resistance curve.
Can BZB84-C20,215 be used for bidirectional ESD protection on a differential pair?
Yes - its dual common-anode structure allows direct connection across differential lines (e.g., CAN_H/CAN_L), with each cathode tied to one line and the anode grounded. This provides symmetrical ±20 V clamping with matched dynamic impedance, validated for IEC 61000-4-2 Level 4 when series impedance is ≥100 Ω.
How does the temperature coefficient affect regulation accuracy over −40 °C to +125 °C?
At 20 V nominal, the temperature coefficient is +14.0 to +18.0 mV/K. Over a 165 °C range, this causes a worst-case drift of +2.31 to +2.97 V - approximately +11.6 % full-scale shift. For precision references, this must be compensated in firmware or paired with a negative-coefficient component in the feedback network.
Is the SOT23 package lead-free and RoHS compliant?
Yes - BZB84-C20,215 is manufactured with lead-free terminations and complies with EU RoHS Directive 2011/65/EU and REACH SVHC regulations. The device uses SnAgCu (SAC305) solder finish and meets JEDEC J-STD-020 moisture sensitivity level 1 (MSL1) for unlimited floor life at ≤30 °C/85 % RH.
