Product details
Overview
BZX84-C10,235 from Nexperia is a ±5 % tolerance Zener voltage regulator diode in SOT23 (TO-236AB) package, rated for 10 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, such as sensor biasing, ADC reference stabilization, and microcontroller reset circuitry.
For engineers reviewing the BZX84-C10,235 datasheet, BZX84-C10,235 pinout, BZX84-C10,235 application, or BZX84-C10,235 equivalent, key selection criteria include its 10 V Zener voltage tolerance (±5 %), thermal resistance (330 K/W junction-to-solder-point), differential resistance (150 Ω max at 5 mA), reverse current (20 μA max at 7.6 V), and SOT23 footprint compatibility with high-density PCB layouts.
Technical Context
This device operates in reverse-bias breakdown mode to maintain stable voltage across its cathode-anode terminals under varying load or input conditions. Its Zener mechanism provides predictable regulation with temperature coefficient of +4.5 mV/K at 5 mA, enabling predictable drift compensation in temperature-sensitive references.
The SOT23 package features three terminals-Anode (Pin 1), Not Connected (Pin 2), and Cathode (Pin 3)-with Pin 2 electrically isolated to reduce parasitic capacitance and improve high-frequency stability. Thermal performance is defined relative to solder point (Rth(j-sp) = 330 K/W), supporting reliable operation up to 150 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 9.4 V to 10.6 V at IZ = 5 mA - defines usable regulation window for 10 V nominal reference |
| Differential Resistance (rdif) | ≤150 Ω at IZ = 5 mA - determines output impedance and load regulation error |
| Reverse Current (IR) | ≤20 μA at VR = 7.6 V - ensures low leakage in standby or high-impedance sensing nodes |
| Total Power Dissipation (Ptot) | 250 mW at Tamb ≤ 25 °C on FR4 PCB - sets maximum continuous DC power handling |
| Non-repetitive Peak Reverse Power | 40 W for tp = 100 μs - supports transient surge suppression without failure |
| Temperature Coefficient (SZ) | +4.5 mV/K at IZ = 5 mA - enables predictable voltage drift vs. ambient for calibration |
| Junction-to-Solder-Point Rth | 330 K/W - quantifies thermal path efficiency for thermal design in compact layouts |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mounted package with 3 leads; 1.3 mm height, 2.9 mm length, 1.3 mm width; optimized for reflow and wave soldering per IPC-7351B.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode | Forward-current entry point; connected to lower-potential node in Zener configuration |
| 2 | Not Connected | Electrically isolated terminal; no internal bond wire; reduces stray capacitance |
| 3 | Cathode | Regulated output node; connected to higher-potential rail; primary thermal path to PCB |
Key Features
| Feature | Design Value |

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 MMBZ5240BLT1G | 10 V, ±5 %, 350 mW Ptot, 100 Ω rdif, SOT23 | Higher power rating allows higher current regulation but larger thermal footprint | Select when >200 mA load current or tighter regulation (<100 Ω rdif) is required |
| Vishay BZX84-C10-TP | 10 V, ±5 %, 250 mW Ptot, 150 Ω rdif, identical SOT23 pinout and marking | No functional difference; qualified to AEC-Q200 Grade 3 for extended temperature range | Select for automotive-adjacent industrial applications requiring -40 °C to +125 °C operation |
Compared with BZX84-C10,235, the MMBZ5240BLT1G offers lower dynamic impedance for improved load regulation but requires thermal redesign due to 350 mW rating, while the BZX84-C10-TP delivers identical electrical behavior with automotive-grade qualification-making it suitable for harsh-environment deployments without layout change.

FAQ
What is the maximum continuous forward current for BZX84-C10,235?
The absolute maximum forward current is 200 mA per limiting values table. However, sustained forward conduction is not intended in Zener operation; this rating supports surge immunity testing and accidental polarity reversal scenarios. For normal use, forward voltage remains ≤0.9 V at 10 mA, confirming safe operation within standard logic-level drive limits.
Can BZX84-C10,235 be used in place of a 10 V linear regulator IC?
No-it functions only as a shunt regulator, requiring an external current-limiting resistor to set operating current. Unlike series regulators, it cannot source load current directly. It is appropriate for low-current reference or clamping roles (e.g., <5 mA loads), but not for powering downstream circuitry. Use only where the application inherently provides controlled bias current.
How does the "235" suffix in BZX84-C10,235 affect specifications?
The "235" is Nexperia's internal package variant code indicating tape-and-reel packaging per EIA-481-D standard, 3000 units per reel, and Pb-free/RoHS-compliant finish. It does not alter electrical or thermal parameters-BZX84-C10,235 shares identical Zener voltage, power rating, and pinout with BZX84-C10 variants bearing other suffixes like ",115" or ",135".
Is BZX84-C10,235 qualified for automotive applications?
No-this part is non-automotive qualified per Revision 7 documentation. It lacks AEC-Q200 stress testing and is not rated for automotive temperature ranges (–40 °C to +125 °C). For automotive use, select Nexperia's BZX84-C10-Q series or Vishay's AEC-Q200-qualified BZX84-C10-TP, which undergo extended temperature cycling and humidity testing.
