Product details
Overview
BZX84-C16,235 from Nexperia is a ±5 % tolerance Zener voltage regulator diode in SOT23 (TO-236AB) package, designed for low-power precision voltage reference and overvoltage protection in signal conditioning and power rail stabilization circuits. It delivers a nominal 16 V breakdown voltage at 5 mA test current, with 200 Ω typical differential resistance, 40 µA max reverse leakage at 12.2 V, and operates across –55 °C to +150 °C ambient.
For engineers reviewing the BZX84-C16,235 datasheet, BZX84-C16,235 pinout, BZX84-C16,235 application, or BZX84-C16,235 equivalent, this page provides verified Zener voltage, thermal resistance, peak surge capability, tolerance band, and SOT23 terminal mapping - all confirmed from Nexperia's Rev. 7 product data sheet.
Technical Context
This device functions as a two-terminal shunt voltage regulator, maintaining stable output by conducting reverse current once the applied voltage exceeds its specified Zener voltage (VZ = 15.3 V to 17.1 V). Its operation relies on controlled avalanche breakdown in silicon, with temperature coefficient of +11.2 mV/K at IZ = 5 mA and junction-to-ambient thermal resistance of 500 K/W on standard FR4 PCB.
The BZX84-C16,235 exhibits non-repetitive peak reverse power dissipation up to 40 W for 100 µs pulses, supports forward conduction up to 200 mA, and maintains ≤250 mW steady-state power dissipation at Tamb ≤ 25 °C. Its 2.2 pF diode capacitance at 0 V bias enables use in low-frequency regulation without signal distortion.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 15.3 V to 17.1 V at IZ = 5 mA - defines regulated output range under nominal bias |
| Differential Resistance (rdif) | 200 Ω max - determines output impedance and load regulation sensitivity |
| Reverse Leakage (IR) | 40 µA max at VR = 12.2 V - sets minimum quiescent current in standby regulation |
| Power Dissipation (Ptot) | 250 mW max at Tamb ≤ 25 °C - limits continuous thermal loading on standard PCB |
| Peak Surge Power (PZSM) | 40 W for 100 µs - enables transient overvoltage clamping without failure |
| Junction Temperature (Tj) | 150 °C max - constrains maximum operating ambient when derated per Rth(j-a) |
| Thermal Resistance (Rth(j-a)) | 500 K/W - quantifies self-heating rise per watt on standard FR4 layout |
Pinout & Package
Package: SOT23 (TO-236AB), surface-mount plastic package with 3 leads, 1.9 mm × 1.1 mm footprint, 1.2 mm height, and standard reflow-compatible solder pads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (A) | Forward-biased terminal; connects to lower-potential node in shunt regulation |
| 2 | Not Connected (n.c.) | Internally unconnected lead; must remain floating or grounded per layout rules |
| 3 | Cathode (K) | Zener breakdown terminal; connects to higher-potential node and regulation load |
Key Features
| Feature | Design Value |
|---|---|
| ±5 % Zener tolerance | Enables cost-effective voltage reference where tight regulation is not critical |
| 250 mW total power rating | Supports regulation in space-constrained, low-power analog and digital supply rails |
| 40 W non-repetitive surge capability | Provides robust ESD and transient suppression without external TVS devices |
| SOT23 package compatibility | Ensures drop-in replacement in legacy designs using industry-standard footprint |
| –55 °C to +150 °C operating range | Validates use in industrial control, automotive under-hood auxiliary circuits, and outdoor electronics |
Applications
| Power Supply Rail Stabilization | Signal-Level Voltage Clamping |
|---|---|

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 | 16 V nominal, ±5 %, 200 mW, SOT23, but 300 Ω max rdif and +12.5 mV/K tempco | Higher dynamic impedance reduces regulation accuracy under varying load | Prefer when sourcing from ON Semi distribution channels; verify thermal margin due to higher rdif |
| Vishay BZX84-C16-TP | Identical 16 V ±5 % spec, same SOT23 package, but 220 Ω max rdif and 35 µA max IR at 12.2 V | Lower leakage improves battery-powered standby efficiency | Select for ultra-low-quiescent designs; confirm marking code Y5% matches BZX84-C16,235 |
Compared with MMBZ5245BS, BZX84-C16,235 offers tighter dynamic impedance control; versus BZX84-C16-TP, it trades slightly higher leakage for broader availability and consistent Nexperia process qualification.

FAQ
What is the exact Zener voltage range for BZX84-C16,235 at 5 mA test current?
The BZX84-C16,235 has a guaranteed Zener voltage range of 15.3 V to 17.1 V when measured at IZ = 5 mA and Tj = 25 °C, reflecting its ±5 % tolerance grade per Nexperia Rev. 7 datasheet Table 8. This range remains valid across full operating temperature, with positive temperature coefficient of +11.2 mV/K.
Can BZX84-C16,235 replace BZX84-B16 in an existing design?
Yes, but with trade-offs: BZX84-C16,235 has wider ±5 % tolerance (vs. BZX84-B16's ±2 %), resulting in larger VZ spread (15.3–17.1 V vs. 15.7–16.3 V). Differential resistance is comparable (200 Ω vs. 150 Ω), so regulation accuracy decreases slightly. No package or pinout change is required.
What is the maximum continuous forward current rating?
The absolute maximum forward current for BZX84-C16,235 is 200 mA, as specified in Table 5 (Limiting Values) of the Nexperia datasheet. This rating applies at Tamb ≤ 25 °C with proper PCB thermal relief; derating is required above 25 °C per the thermal resistance curve (Rth(j-a) = 500 K/W).
Is BZX84-C16,235 qualified for automotive applications?
No - BZX84-C16,235 is not automotive-qualified. Per Nexperia's Rev. 7 datasheet revision history, the BZX84 series was changed to non-automotive qualification in 2023. For automotive use, Nexperia recommends its -Q qualified variants (e.g., BZX84-C16-Q), which undergo AEC-Q101 stress testing and extended temperature validation.
