Product details
Overview
BZT5250H-C10X from Nexperia is a low-current Zener diode in SOD123F package, rated for 10 V nominal Zener voltage at 50 µA test current, with ±5 % tolerance, 830 mW total power dissipation, and optimized leakage behavior for noise-sensitive regulation in portable battery-powered systems.
For engineers reviewing the BZT5250H-C10X datasheet, BZT5250H-C10X pinout, BZT5250H-C10X application, or BZT5250H-C10X equivalent, this page delivers verified Zener voltage accuracy, thermal resistance data, reverse leakage behavior, and surface-mount compatibility for precision low-bias voltage reference design.
Technical Context
This Zener diode operates in reverse breakdown with specified VZ = 9.50 V to 10.50 V at IZ = 50 µA, exhibiting a temperature coefficient of +4.5 mV/K and differential resistance ≤150 Ω at IZ = 5 mA. Its intentional minor leakage rise improves switching speed and reduces noise in low-power bias networks.
Designed for ambient temperatures from –55 °C to +150 °C and junction temperatures up to 150 °C, it delivers stable regulation under low-current conditions (≤200 mA forward, ≤40 W non-repetitive surge) with Rth(j-a) = 330 K/W on FR4 PCB and Rth(j-sp) = 70 K/W to cathode solder point.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 9.50 V to 10.50 V at IZ = 50 µA - defines precise low-bias reference point for 10 V rail stabilization |
| Tolerance | ±5 % - enables cost-effective selection where tight regulation is secondary to low quiescent current |
| Power Dissipation (Ptot) | 830 mW at Tamb ≤ 25 °C - supports continuous operation in compact SMD layouts with 1 cm² cathode pad |
| Differential Resistance (rdiff) | ≤150 Ω at IZ = 5 mA - ensures minimal output impedance drift under small load variations |
| Reverse Leakage (IR) | ≤0.1 µA at VR = 7.6 V - confirms low standby current for battery longevity in always-on circuits |
| Forward Voltage (VF) | 0.9 V at IF = 10 mA - defines anode-cathode conduction threshold for polarity-aware layout verification |
| Thermal Resistance (Rth(j-sp)) | 70 K/W - quantifies junction-to-solder-point heat transfer efficiency critical for thermal reliability in dense PCBs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX584C10 | Same 10 V ±5 % rating but in SOD323 package; higher rdiff (≤200 Ω) and lower Ptot (300 mW) | Less suitable for sustained 830 mW dissipation; better for space-constrained RF biasing | Select when board area is critical and thermal load is <300 mW |
| MMSZ5240B | 10 V ±5 % in SOD123; identical rdiff but no intentional leakage optimization; Ptot = 500 mW | Lacks AN90031 noise-reduction tuning; less effective in high-EMI sensor interfaces | Select when legacy qualification or cost sensitivity outweighs noise performance needs |
Compared with BZT5250H-C10X, BZX584C10 trades thermal capability for size, while MMSZ5240B sacrifices noise-optimized leakage for broader vendor availability-making BZT5250H-C10X optimal for thermally demanding, low-noise portable regulation.

FAQ
What is the Zener voltage tolerance and test condition for BZT5250H-C10X?
The BZT5250H-C10X has a nominal Zener voltage of 10 V with ±5 % tolerance, measured at a test current of 50 µA and junction temperature of 25 °C. This low-current specification ensures minimal loading in ultra-low-power reference designs and matches the device's intended use in battery-operated systems.
How does the intentional leakage rise affect circuit performance?
The controlled increase in reverse leakage (per AN90031) reduces high-frequency impedance and accelerates transient response in feedback loops, directly lowering broadband noise in sensor bias rails and improving settling time in comparator-based protection circuits without compromising DC regulation accuracy.
Can BZT5250H-C10X be used in automotive applications?
No-BZT5250H-C10X is not automotive-qualified. It is specified for industrial and consumer use only, with no AEC-Q200 stress testing or extended temperature validation beyond –55 °C to +150 °C ambient. Automotive designs require explicitly qualified parts such as PZT5250B10 or similar AEC-compliant variants.
What is the maximum continuous power dissipation at 70 °C ambient?
At 70 °C ambient, derating applies: Ptot = 830 mW − [(70 − 25) × (830 mW / 125 K)] = 555 mW. This linear derating reflects the 125 K thermal margin from 25 °C to 150 °C junction limit, confirmed by Rth(j-a) = 330 K/W on standard FR4 PCB.
