Product details
Overview
BZX84-C16,215 from Nexperia is a ±5 % tolerance Zener voltage regulator diode in SOT23 (TO-236AB) package, rated for 16 V nominal breakdown voltage at 5 mA, 250 mW total power dissipation, and 40 W non-repetitive peak reverse power. It serves as a precision reference or overvoltage clamp in low-power analog supply rails and sensor biasing circuits.
For engineers reviewing the BZX84-C16,215 datasheet, BZX84-C16,215 pinout, BZX84-C16,215 application, or BZX84-C16,215 equivalent, key selection criteria include Zener voltage tolerance (±5 %), differential resistance (200 Ω max at IZ = 5 mA), temperature coefficient (+11.2 mV/K), reverse current (≤0.05 μA at VR = 12.8 V), and thermal resistance (500 K/W junction-to-ambient).
Technical Context
This device operates in reverse-bias breakdown mode to maintain stable voltage across its terminals under varying load or input conditions. Its Zener voltage is specified at 5 mA test current with a maximum differential resistance of 200 Ω, ensuring predictable regulation within low-current applications.
The diode exhibits a positive temperature coefficient of +11.2 mV/K at IZ = 5 mA, indicating voltage increases with junction temperature - a critical factor when used in thermally coupled circuits or unregulated environments. It is not rated for automotive use per Rev. 7 (2023) documentation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 15.3 V to 17.1 V at IZ = 5 mA - defines operating regulation range under standard test conditions |
| Differential Resistance (rdif) | ≤200 Ω at IZ = 5 mA - determines output impedance and voltage deviation under load changes |
| Reverse Current (IR) | ≤0.05 μA at VR = 12.8 V - ensures minimal leakage before breakdown onset |
| Temperature Coefficient (SZ) | +11.2 mV/K at IZ = 5 mA - quantifies voltage drift per degree Celsius rise in junction temperature |
| Total Power Dissipation (Ptot) | 250 mW at Tamb ≤ 25 °C on FR4 PCB - sets maximum continuous DC power handling capability |
| Non-repetitive Peak Reverse Power (PZSM) | 40 W for tp = 100 μs - supports transient surge suppression without damage |
| Junction Temperature (Tj) | −55 °C to +150 °C - defines operational thermal envelope for reliability |
Pinout & Package
Package: SOT23 (TO-236AB), surface-mount plastic package with 3 leads, 1.9 mm × 1.1 mm footprint, 1.4 mm height, and standard reflow/wave soldering land patterns.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (A) | Connected to lower-potential side in reverse-bias configuration; carries forward current during conduction |
| 2 | Not Connected (n.c.) | Internally unconnected lead; must remain floating - no PCB trace or component connection |
| 3 | Cathode (K) | Connected to higher-potential side in reverse-bias; defines polarity for Zener operation and marking orientation |
Key Features
| Feature | Design Value |
|---|---|
| ±5 % Zener voltage tolerance | Enables cost-effective voltage referencing where tight regulation is not required, e.g., non-critical biasing |
| 250 mW power rating | Suitable for low-power signal conditioning, microcontroller reset circuits, and sensor interface protection |
| 40 W surge capability | Provides transient overvoltage clamping in ESD-prone interfaces without external TVS devices |
| 150 °C max junction temperature | Supports operation in industrial ambient environments up to +125 °C with appropriate derating |
| SOT23 package compatibility | Enables high-density PCB layouts and automated assembly using standard pick-and-place and reflow processes |
Applications
| Power Supply Reference | Sensor Biasing |
|---|---|
Use Scenario: Providing stable 16 V reference for op-amp feedback networks in linear regulators. IC Role / Device Role / Timing Role: Zener diode operating in reverse breakdown to fix reference node voltage. Use Value: Delivers <±0.8 V regulation window over temperature and current variation, sufficient for non-precision analog stages. |
Use Scenario: Biasing photodiode or RTD measurement circuits requiring fixed reverse bias voltage. IC Role / Device Role / Timing Role: Voltage clamp establishing known reverse bias point for transducer operation. Use Value: Maintains consistent sensor operating point with <0.05 μA leakage, minimizing measurement offset error. |
| Microcontroller Reset Circuit | ESD Protection Clamp |
Use Scenario: Generating clean reset signal during power-up by holding reset line low until supply reaches 16 V threshold. IC Role / Device Role / Timing Role: Zener-based threshold detector in RC-reset network. Use Value: Enables deterministic reset release timing with ±5 % voltage accuracy and thermal stability up to +125 °C ambient. |
Use Scenario: Protecting I/O pins of communication ICs (e.g., UART, SPI) against fast transients. IC Role / Device Role / Timing Role: Low-capacitance (≤75 pF) shunt clamp absorbing ESD energy. Use Value: Limits voltage excursion to ≤17.1 V during 40 W/100 μs surges while adding <1 pF parasitic capacitance to signal path. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MMBZ5245BS-7-F | 16 V nominal, ±5 %, 200 mW, SOT23 - identical Zener voltage and tolerance but 300 Ω max rdif at 5 mA | Higher dynamic impedance reduces regulation accuracy under variable load vs. BZX84-C16,215's 200 Ω max | Select when second-source qualification is required and slightly looser regulation is acceptable |
| Vishay BZX84-C15-TP | 15 V nominal, ±5 %, 250 mW, SOT23 - 1 V lower Zener voltage with same package and power rating | Requires circuit redesign to accommodate 15 V reference instead of 16 V; not drop-in compatible | Choose only if system-level calibration allows 15 V reference and tighter voltage margin is needed |
Compared with MMBZ5245BS-7-F, BZX84-C16,215 offers lower differential resistance for improved load regulation; compared with BZX84-C15-TP, it provides higher reference voltage without sacrificing thermal or surge performance.

FAQ
What is the maximum reverse current for BZX84-C16,215 at 12.8 V?
The maximum reverse current is 0.05 μA at VR = 12.8 V and Tj = 25 °C, per Table 8 of the Rev. 7 datasheet. This ultra-low leakage ensures minimal power loss and stable biasing in high-impedance circuits such as sensor front-ends or precision comparators.
Can BZX84-C16,215 be used in automotive applications?
No - Rev. 7 (January 2023) explicitly states that BZX84 series devices are non-automotive qualified. They lack AEC-Q101 stress testing and are not warranted for automotive environments. For automotive use, Nexperia offers separate -Q qualified variants like BZX84-C16,215-Q.
What is the thermal resistance from junction to ambient?
Rth(j-a) is 500 K/W when mounted on an FR4 PCB with single-sided 70 µm copper, tin-plated, and standard footprint. This value governs steady-state temperature rise: at 250 mW dissipation, junction temperature rises ~125 °C above ambient, requiring derating above +25 °C ambient.
How does the temperature coefficient affect regulation accuracy?
With a +11.2 mV/K coefficient at IZ = 5 mA, the Zener voltage increases by ~1.12 V over a 100 °C junction temperature rise. In a +85 °C ambient design with self-heating, expect ~0.9 V upward shift - requiring compensation in precision references or limiting use to narrow thermal ranges.
