Product details
Overview
BZX8450-C13-Q from Nexperia is a low-current Zener voltage regulator diode in SOT23 package, designed for precision biasing and voltage reference in automotive and portable electronics. It delivers a nominal 13 V regulation at 50 µA test current, with ±5 % tolerance, 170 Ω differential resistance at 5 mA, and AEC-Q101 qualification for under-hood applications.
For engineers reviewing the BZX8450-C13-Q datasheet, BZX8450-C13-Q pinout, BZX8450-C13-Q application, or BZX8450-C13-Q equivalent, this page provides verified electrical characteristics, thermal behavior, automotive-grade reliability data, and real-world use context for low-power voltage stabilization in battery-constrained systems.
Technical Context
This Zener diode operates in reverse breakdown mode with a specified working voltage of 12.35 V (min) to 13.65 V (max) at IZ = 50 µA. Its temperature coefficient is +7.0 mV/K, indicating positive drift with junction temperature rise - critical for stable reference design across −55 °C to +150 °C ambient.
The device exhibits 0.05 µA maximum reverse leakage at VR = 9.8 V and features 80 pF capacitance at 0 V, making it suitable for low-frequency regulation where capacitive loading must be minimized. Thermal resistance from junction to solder point is 330 K/W, enabling predictable derating on standard FR4 PCBs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Zener Voltage | 13 V at IZ = 50 µA - defines primary regulation point for low-bias circuits |
| Voltage Tolerance | ±5 % - supports cost-sensitive designs where tighter tolerance is not required |
| Differential Resistance | 170 Ω max at IZ = 5 mA - determines output impedance and load regulation error |
| Forward Voltage | 0.9 V max at IF = 10 mA - ensures minimal forward conduction loss during polarity reversal |
| Total Power Dissipation | 250 mW at Tamb ≤ 25 °C - sets maximum continuous power handling on standard PCB |
| Junction Temperature Limit | 150 °C - enables operation in under-hood automotive environments |
| AEC-Q101 Qualified | Yes - validated for automotive discrete semiconductor stress testing per Rev. D |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (A) | Connects to lower-potential node in reverse-biased Zener configuration |
| 2 | Not Connected (n.c.) | Internally unconnected; must remain floating - no PCB trace or pad required |
| 3 | Cathode (K) | Connects to higher-potential node; serves as voltage reference output terminal |
Key Features
| Feature | Design Value |
|---|---|
| Low test current operation | Specified at 50 µA - enables regulation in micro-power sensor nodes and sleep-mode circuits |
| Optimized leakage profile | Intentional minor IR rise (vs. B-series) - improves switching speed and reduces noise in feedback paths |
| Automotive qualification | AEC-Q101 compliant - meets vibration, temperature cycling, and ESD robustness requirements for Tier-1 modules |
| Thermal performance | Rth(j-sp) = 330 K/W - allows accurate thermal modeling when mounted on cathode-tab solder points |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C13 | Non-AEC-Q101; ±5 % tolerance; same VZ range but higher rdiff (200 Ω max) | Limited to commercial-grade consumer electronics; not qualified for automotive temperature cycling | Select when cost is prioritized over automotive reliability and thermal derating margin is sufficient |
| MMSZ5243B | SOD-123 package; ±5 %; 13 V nominal; rdiff = 30 Ω typical - lower impedance but larger footprint | Higher power dissipation (500 mW) but lacks intentional leakage optimization for noise reduction | Choose when lower dynamic impedance is required and board space permits larger SOD-123 layout |
Compared with BZX8450-C13-Q, BZX84-C13 sacrifices automotive qualification and thermal robustness for lower cost, while MMSZ5243B trades SOT23 compactness and noise-optimized leakage for improved regulation stiffness - requiring trade-offs in size, reliability, or signal integrity.

FAQ
What is the maximum reverse leakage current for BZX8450-C13-Q at 9.8 V?
The maximum reverse leakage current (IR) is 0.05 µA at VR = 9.8 V and Tj = 25 °C, as specified in Table 8 of the datasheet. This ultra-low leakage enables use in battery-powered systems where standby current must remain below 100 nA.
Can BZX8450-C13-Q be used in place of BZX84-C13 in an automotive design?
No - BZX8450-C13-Q is AEC-Q101 qualified with extended temperature range (−55 °C to +150 °C) and validated automotive stress testing, whereas BZX84-C13 lacks this qualification and is rated only for commercial temperature ranges. Substitution requires full requalification.
What is the thermal resistance from junction to solder point, and how is it measured?
Rth(j-sp) is 330 K/W, measured with the device mounted on an FR4 PCB using single-sided 70 µm copper, tin-plated, and standard SOT23 footprint. The solder point refers specifically to the cathode tab, as defined in Table 6 of the datasheet.
Why does the BZX8450-C13-Q have a different leakage profile than the B-series variant?
The C-series intentionally increases leakage slightly versus the B-series to reduce minority-carrier lifetime, which improves switching speed and suppresses noise in feedback loops - as documented in Application Note AN90031. This makes it preferred for dynamic reference applications.
