Product details
Overview
BZT5250H-C10-Q from Nexperia is a low-current Zener diode in SOD123F package, providing precise 10 V voltage regulation at 50 µA test current with ±5 % tolerance. It delivers 830 mW total power dissipation, features low leakage optimized for fast switching and noise reduction, and is AEC-Q101 qualified for automotive load-dump protection and ECU reference circuits.
For engineers reviewing the BZT5250H-C10-Q datasheet, BZT5250H-C10-Q pinout, BZT5250H-C10-Q application, or BZT5250H-C10-Q equivalent, key selection criteria include its 10 V nominal Zener voltage, 50 µA regulation test current, SOD123F surface-mount footprint, AEC-Q101 qualification status, and intentional leakage optimization per AN90031 for noise-sensitive automotive subsystems.
Technical Context
This Zener diode operates as a shunt voltage regulator with specified characteristics at Tj = 25 °C, using a low 50 µA test current to enable stable biasing in ultra-low-power sensor interfaces and battery-backed monitoring circuits. Its differential resistance is ≤150 Ω at IZ = 5 mA, and temperature coefficient is +4.5 mV/K - enabling predictable drift compensation in automotive ambient ranges (−40 °C to +125 °C).
The device exhibits 0.1 µA reverse current at VR = 7.6 V, confirming tight regulation near nominal voltage, and integrates an intentional minor leakage rise per AN90031 to reduce switching transients and improve RF noise immunity in infotainment power rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| Zener Voltage VZ | 9.50 V to 10.50 V at IZ = 50 µA - ensures ±5 % regulation accuracy for 10 V reference generation under minimal bias. |
| Power Dissipation Ptot | 830 mW at Tamb ≤ 25 °C - supports continuous operation in compact automotive PCB layouts with 1 cm² cathode pad. |
| Differential Resistance rdiff | ≤150 Ω at IZ = 5 mA - maintains tight voltage stability against load current variations in feedback networks. |
| Forward Voltage VF | 0.9 V at IF = 10 mA - enables predictable forward conduction for polarity protection or clamping in dual-diode configurations. |
| Reverse Current IR | 0.1 µA at VR = 7.6 V - confirms sharp knee and low quiescent loss in standby mode for always-on vehicle modules. |
| Junction Temperature | 150 °C maximum - allows reliable operation in under-hood environments with peak thermal stress. |
| AEC-Q101 Qualified | Yes - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD per AEC standard. |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C10 | Same 10 V nominal, ±5 %, but SOT23 package (larger footprint, higher Rth(j-a) = 330 K/W) | Lacks AEC-Q101 qualification and intentional leakage optimization | Select when cost sensitivity outweighs automotive qualification and noise performance requirements |
| MMSZ5240B | 10 V, ±5 %, SOD123 package but rated only to 500 mW Ptot; no AEC-Q101 or AN90031 compliance | Not validated for automotive temperature cycling or load-dump stress | Use only in commercial-grade consumer electronics where extended thermal and surge reliability are not required |
Compared with BZX84-C10 and MMSZ5240B, the BZT5250H-C10-Q provides superior thermal performance in SOD123F (Rth(j-sp) = 70 K/W), guaranteed automotive qualification, and application-specific leakage tuning - making it the sole choice for safety-critical 10 V reference in AEC-compliant systems.

FAQ
What is the Zener voltage tolerance for BZT5250H-C10-Q?
The BZT5250H-C10-Q has a nominal Zener voltage of 10 V with a tolerance of ±5 %, verified at IZ = 50 µA and Tj = 25 °C. This corresponds to a guaranteed VZ range of 9.50 V to 10.50 V under specified test conditions, as confirmed in Table 8 of the official Nexperia datasheet Rev. 2 (July 2024).
Is BZT5250H-C10-Q suitable for automotive applications?
Yes - the BZT5250H-C10-Q is fully qualified to AEC-Q101 for discrete semiconductors, including stress tests for temperature cycling, high-temperature reverse bias, and ESD. It is explicitly recommended for automotive use in the datasheet and supports operation from −55 °C to +150 °C junction temperature.
How does the "intentional minor rise of leakage current" benefit circuit design?
This feature, detailed in Application Note AN90031, optimizes fast switching and reduces electromagnetic noise by tailoring the reverse recovery behavior. In practice, it lowers overshoot and ringing during transient suppression in CAN/LIN bus power rails and improves signal integrity in analog sensor interfaces.
What is the maximum continuous power dissipation for BZT5250H-C10-Q?
The maximum continuous total power dissipation is 830 mW at ambient temperature ≤25 °C with a 1 cm² cathode copper pad on FR4 PCB, as defined in Table 5 (Limiting Values) and Table 1 (Quick Reference Data). Derating applies above 25 °C per the Rth(j-a) = 330 K/W thermal resistance specification.
