Product details
Overview
BZX84C10Q-13-F from Diodes Incorporated is a 10 V, 350 mW surface-mount Zener diode in SOT23 package, rated for 5 mA test current with ±6% tolerance (9.4–10.6 V), 20 Ω dynamic impedance at 5 mA, and 0.2 µA maximum reverse leakage at 7.0 V. It serves as a precision voltage reference or overvoltage clamp in low-power analog signal conditioning circuits.
For engineers reviewing the BZX84C10Q-13-F datasheet, BZX84C10Q-13-F pinout, BZX84C10Q-13-F application, or BZX84C10Q-13-F equivalent, key selection criteria include Zener voltage accuracy, thermal resistance (357 °C/W), AEC-Q101 qualification, RoHS/Green compliance, and SOT23 footprint compatibility in space-constrained PCB layouts.
Technical Context
This Zener diode operates in reverse breakdown mode with a nominal 10 V regulation point at 5 mA. Its planar die construction ensures stable voltage characteristics across temperature and lifetime, supported by a temperature coefficient of +4.5 mV/°C near 10 V.
The device exhibits low dynamic impedance (20 Ω @ 5 mA) and minimal capacitance (~15 pF at 1 V reverse bias), making it suitable for DC reference and low-frequency stabilization-not RF or high-speed transient suppression.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 10 V nominal, 9.4–10.6 V range at 5 mA - defines precise DC reference level for feedback or sensing circuits |
| Power Dissipation | 350 mW - sets maximum continuous power handling on FR-4 board with ambient cooling |
| Zener Impedance (ZZT) | 20 Ω @ 5 mA - determines regulation stiffness under load variation |
| Reverse Leakage (IR) | 0.2 µA @ 7.0 V - ensures minimal quiescent current draw in battery-powered systems |
| Thermal Resistance (RθJA) | 357 °C/W - quantifies junction-to-ambient heat rise per watt, critical for thermal derating above 25°C |
| Temperature Coefficient | +4.5 mV/°C - enables predictable drift compensation in temperature-stable references |
Pinout & Package
Package: SOT23 - 3-terminal surface-mount plastic case, 2.4 mm × 1.3 mm footprint, 0.9 mm height, UL 94V-0 rated, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Forward conduction terminal | Connected to lower potential side in reverse-biased Zener configuration |
| Cathode (Pin 2) | Zener breakdown terminal | Connected to higher potential side; voltage regulation occurs between this and anode |
| No-connect / Heat sink (Pin 3) | Internal die attachment pad | Electrically isolated; provides mechanical stability but no electrical function |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD robustness |
| Green, halogen-free construction | Meets <900 ppm Br/Cl and <1000 ppm Sb; supports eco-compliant industrial and automotive designs |

| SOT23 tape-and-reel packaging (10,000 pcs) | Enables high-yield pick-and-place assembly without manual handling or rework |
Applications
| Power Supply Feedback Reference | Overvoltage Clamp for MCU I/O |
|---|---|
Use Scenario: Regulating output voltage in low-current linear regulators or switching converter feedback loops. IC Role / Device Role: Provides stable 10 V reference for error amplifier input. Use Value: Enables ±1% output accuracy with minimal external components and no active circuitry. |
Use Scenario: Protecting 3.3 V or 5 V microcontroller GPIO pins from transient overvoltage events. IC Role / Device Role: Shunts excess energy to ground when input exceeds 10 V threshold. Use Value: Limits clamping voltage to safe levels while drawing only 0.2 µA leakage during normal operation. |
| ADC Reference Stabilization | Industrial Sensor Biasing |
Use Scenario: Supplying clean, low-drift reference voltage to 12-bit SAR ADCs in data acquisition modules. IC Role / Device Role: Acts as passive voltage source replacing more complex IC references where cost and size are constrained. Use Value: Delivers 10 V reference with <±0.5% drift over –40°C to +85°C due to +4.5 mV/°C TC compensation. |
Use Scenario: Biasing resistive temperature detectors (RTDs) or bridge sensors requiring stable excitation voltage. IC Role / Device Role: Supplies regulated 10 V excitation to sensor elements independent of supply rail fluctuations. Use Value: Reduces measurement error caused by supply ripple, improving system resolution by up to 1 LSB in 16-bit systems. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5240B-7-F | 10 V nominal, 350 mW, 17 Ω ZZT, but not AEC-Q101 qualified | Limited to commercial-grade consumer electronics; lacks automotive reliability validation | Select when AEC-Q101 is not required and tighter ZZT is prioritized over qualification |
| BZX84-C10-E3-08 | Same 10 V spec, SOT23, but Vishay part with 25 Ω ZZT and RoHS-compliant (non-Green) molding compound | Acceptable for industrial use but may not meet halogen-free requirements in EU automotive programs | Choose if Green compliance is waived and second-source availability is needed |
Compared with MMBZ5240B-7-F and BZX84-C10-E3-08, BZX84C10Q-13-F uniquely combines AEC-Q101 qualification, Green/halogen-free construction, and 20 Ω ZZT, making it the preferred choice for automotive and high-reliability industrial voltage reference designs where regulatory compliance and parametric consistency are mandatory.

FAQ
What is the maximum reverse voltage before breakdown for BZX84C10Q-13-F?
The nominal Zener voltage is 10 V at 5 mA test current, with a guaranteed range of 9.4 V to 10.6 V. Breakdown begins gradually below this point; the device is specified to maintain ≤0.2 µA reverse leakage up to 7.0 V, and full regulation occurs above ~9.0 V depending on current and temperature.
Is BZX84C10Q-13-F suitable for use in automotive applications?
Yes-it is explicitly qualified to AEC-Q101 standards, including stress testing for temperature cycling, high-temperature reverse bias, and electrostatic discharge. The "Q" suffix denotes automotive grade, and its Green/halogen-free construction meets stringent OEM material compliance requirements.
How does thermal derating affect power handling above 25°C?
Power dissipation must be linearly reduced above 25°C ambient using the 357 °C/W thermal resistance. At 85°C ambient, maximum allowable power drops to approximately 195 mW (calculated as 350 mW × (1 − (85−25)/357)), ensuring junction temperature remains within –65°C to +150°C limits.
Can BZX84C10Q-13-F replace a 1N4740A in existing designs?
No-while both are 10 V Zeners, the 1N4740A is a through-hole 1 W device in DO-41 package with different thermal behavior, impedance (20 Ω vs. 22 Ω), and mounting. BZX84C10Q-13-F is SOT23, 350 mW, and optimized for surface-mount automation-not a drop-in replacement without layout and thermal redesign.
