Product details
Overview
BZX84-C3V0,215 from Nexperia is a ±5 % tolerance Zener voltage regulator diode in SOT23 (TO-236AB) package, rated for 3.0 V nominal breakdown at 5 mA, with 95 Ω max differential resistance and ≤250 mW total power dissipation. It provides stable reference voltage in low-power linear regulators and overvoltage protection circuits for microcontroller I/O rails.
For engineers reviewing the BZX84-C3V0,215 datasheet, BZX84-C3V0,215 pinout, BZX84-C3V0,215 application, or BZX84-C3V0,215 equivalent, key selection criteria include Zener voltage tolerance (±5 %), thermal resistance (330 K/W to solder point), non-repetitive peak reverse power (40 W), and cathode-anode polarity confirmation for PCB layout and ESD-safe biasing.
Technical Context
This device operates as a two-terminal shunt voltage reference, conducting in reverse breakdown when reverse-biased above its 3.0 V nominal Zener voltage. Its temperature coefficient is 0.0 mV/K at IZ = 5 mA, minimizing drift across ambient temperatures from −55 °C to +150 °C.
The diode exhibits 10 μA max reverse current at VR = 1.0 V and 6.0 A non-repetitive peak reverse current capability under 100 μs square-wave pulses. Its 450 pF capacitance at 1 MHz and 0 V reverse bias supports use in low-frequency regulation-not RF bypass or high-speed clamping.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 2.80 V to 3.20 V at IZ = 5 mA - defines usable regulation window for 3.0 V rail stabilization |
| Differential Resistance (rdif) | ≤95 Ω - limits output impedance and load-induced voltage deviation under varying current |
| Power Dissipation (Ptot) | 250 mW at Tamb ≤ 25 °C on FR4 PCB - sets maximum continuous DC power before thermal derating |
| Reverse Current (IR) | ≤10 μA at VR = 1.0 V - ensures minimal leakage in standby or low-current bias networks |
| Peak Reverse Power (PZSM) | 40 W for tp = 100 μs - enables transient overvoltage suppression without failure |
| Junction Temperature (Tj) | −55 °C to +150 °C - supports operation in industrial and extended-temperature environments |
Pinout & Package
Package: SOT23 (TO-236AB), 3-lead surface-mount plastic package with standard footprint per Figure 12 (reflow) and Figure 13 (wave soldering); dimensions: 2.9 mm × 1.3 mm × 1.0 mm (L × W × H).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (A) | Forward-biased terminal; connects to lower-potential node in regulation path |
| 2 | Not Connected (n.c.) | Internal die pad not electrically bonded; must be left floating or grounded per layout best practice |
| 3 | Cathode (K) | Reverse-biased terminal; connects to regulated voltage node and current-limiting resistor |
Key Features
| Feature | Design Value |
|---|---|
| ±5 % Zener tolerance | Enables cost-optimized voltage reference where tight regulation is not required (e.g., power-on reset thresholds) |
| 250 mW power rating | Supports continuous regulation in sub-10 mA bias networks without heatsinking on standard FR4 PCB |
| Non-repetitive 40 W surge rating | Withstands ESD transients (IEC 61000-4-2 Level 4) and inductive switch-off spikes without degradation |
| Low 10 μA leakage at 1 V | Minimizes quiescent current in battery-powered sensor nodes and always-on monitoring circuits |
| SOT23 footprint compatibility | Enables automated placement and reflow assembly alongside other logic and analog ICs on dense PCBs |
Applications
| Microcontroller I/O Protection | Low-Power Voltage Reference |
|---|---|
Use Scenario: Clamping 3.3 V GPIO lines against ESD and supply overshoot during hot-plug events. IC Role / Device Role / Timing Role: Shunt regulator placed between I/O pin and ground, with series current-limiting resistor. Use Value: 3.0 V Zener threshold prevents damage to CMOS input stages while maintaining signal integrity below 3.0 V. |
Use Scenario: Generating stable 3.0 V reference for ADC biasing in portable medical sensors. IC Role / Device Role / Timing Role: Two-terminal passive reference source supplying <100 μA to precision op-amp buffer. Use Value: 0.0 mV/K tempco and ≤95 Ω dynamic impedance ensure <1 LSB error across −20 °C to +70 °C operating range. |
| DC-DC Feedback Divider | Power-On Reset Threshold |
Use Scenario: Setting feedback voltage of adjustable buck converter (e.g., LM3671) to regulate 3.0 V output. IC Role / Device Role / Timing Role: Replaces top resistor in resistive divider to fix reference node at 3.0 V independent of input variation. Use Value: Eliminates ratio drift from resistor tolerance and temperature coefficients-improves output accuracy to ±3 % over line/load/temperature. |
Use Scenario: Triggering POR circuit when main 3.3 V rail rises above valid operating level. IC Role / Device Role / Timing Role: Anode tied to ground, cathode connected to POR comparator input via pull-up; conducts when rail ≥3.0 V. Use Value: Sharp knee at 3.0 V enables clean, jitter-free reset assertion with <100 ns delay vs. RC-based alternatives. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5226BS-7-F | 3.0 V ±5 %, 200 mW, SOT23, 100 Ω rdif, 100 μA IR @ 1 V | Higher leakage and impedance reduce accuracy in precision references | Prefer for cost-sensitive consumer designs where 100 μA leakage is acceptable |
| BZX84-C3V3,215 | 3.3 V ±5 %, identical package, 95 Ω rdif, 5 μA IR @ 1 V | 0.3 V higher VZ shifts regulation point; lower leakage improves low-power standby | Select when system requires tighter margin above 3.3 V logic threshold or lower standby current |
Compared with BZX84-C3V0,215, MMBZ5226BS-7-F trades regulation accuracy for lower unit cost, while BZX84-C3V3,215 offers improved leakage performance at the expense of 0.3 V higher reference voltage-critical for POR timing and ADC full-scale alignment.

FAQ
What is the maximum continuous forward current for BZX84-C3V0,215?
The absolute maximum forward current is 200 mA per limiting values table. However, sustained forward conduction is not intended-this device is designed for reverse-bias Zener operation. Forward voltage is 0.9 V max at 10 mA, and continuous forward bias risks thermal overstress due to low thermal resistance to ambient (500 K/W).
Can BZX84-C3V0,215 be used in place of a 3.3 V Zener diode?
No-it is specified for 3.0 V nominal breakdown (2.80–3.20 V range). Substituting it for a 3.3 V part would cause premature conduction, potentially pulling down a 3.3 V rail or mis-triggering a POR circuit. Use BZX84-C3V3,215 for 3.3 V applications, which has a 3.10–3.50 V range and lower 5 μA leakage at 1 V.
How does the "215" suffix affect electrical specifications?
The "215" denotes tape-and-reel packaging per ordering information Table 3: 3,000 units per reel, 8 mm tape width, 4 mm pitch. It does not alter electrical parameters-BZX84-C3V0,215 shares identical Zener voltage, power rating, and thermal characteristics with BZX84-C3V0,235 (10,000/reel) or BZX84-C3V0,210 (bulk).
Is BZX84-C3V0,215 qualified for automotive applications?
No-per Revision History section 13, this revision (Rev. 7, Jan 2023) explicitly states products changed to non-automotive qualification. Automotive-grade equivalents (e.g., BZX84-Q series) require separate part numbers and are qualified to AEC-Q101. Use only in industrial, consumer, or computing applications.
