Product details
Overview
BZT5250H-C13X from Nexperia is a low-current Zener diode in SOD123F package, rated for 13 V nominal regulation at 50 µA test current, with ±5 % tolerance, 830 mW total power dissipation, and 9.8 Ω differential resistance at 5 mA. It serves as a precision voltage reference or low-power shunt regulator in battery-powered sensor nodes and portable microcontroller reset circuits.
For engineers reviewing the BZT5250H-C13X datasheet, BZT5250H-C13X pinout, BZT5250H-C13X application, or BZT5250H-C13X equivalent, this page delivers verified electrical characteristics, thermal behavior, SOD123F mounting details, and real-world use cases for low-bias voltage stabilization.
Technical Context
This Zener operates in reverse breakdown with a specified 13 V working voltage (12.35–13.65 V range) at IZ = 5 mA, exhibiting a temperature coefficient of +7.0 mV/K and 150 pF capacitance at 0 V. Its low 50 µA test current enables stable regulation under ultra-low standby bias.
The device features intentional leakage optimization per AN90031 for fast switching transients and reduced noise in signal-path references. Thermal resistance from junction to solder point is 150 K/W on standard FR4 PCB, supporting reliable operation up to 150 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Zener Voltage | 13 V (12.35–13.65 V range at 5 mA; enables precise mid-range rail monitoring) |
| Tolerance | ±5 % (C-series grading; supports cost-sensitive designs where tight regulation is secondary to low quiescent current) |
| Test Current | 50 µA (enables stable regulation in sub-100 µA supply domains like RTC backup or wake-up comparators) |
| Differential Resistance | 9.8 Ω at 5 mA (low impedance ensures minimal output voltage shift under load variation) |
| Total Power Dissipation | 830 mW at Tamb ≤ 25 °C (supports short-duration surge handling with 40 W non-repetitive peak capability) |
| Forward Voltage | 0.9 V at 10 mA (defines forward conduction threshold for polarity protection or clamping) |
| Junction Temperature Limit | 150 °C (sets maximum operating envelope for industrial ambient conditions) |
Pinout & Package
SOD123F surface-mount plastic package: 2.6 mm × 1.6 mm × 1.1 mm body, flat lead profile optimized for automated placement and reflow soldering on FR4 PCBs with single-sided copper.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; marking bar identifies this terminal for correct orientation during assembly |
| 2 | Anode (A) | Connected to ground or lower-potential rail; forms reverse-biased junction for Zener action |
Key Features
| Feature | Design Value |
|---|---|
| Low test current operation | Specified at 50 µA - enables stable regulation in battery-backed circuits with nanoampere standby budgets |
| Optimized leakage profile | Intentional minor rise per AN90031 - reduces switching noise and improves transient response in reference paths |
| Thermal performance | Rth(j-sp) = 150 K/W - allows predictable derating on standard PCB layouts without thermal vias |
| Small-form-factor packaging | SOD123F footprint - saves board space in wearables and compact IoT modules while maintaining solder joint reliability |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZT5250H-B13 | ±2 % tolerance (tighter), 12.7–13.3 V range, 9.8 Ω rdiff, same SOD123F package | Used where tighter voltage stability is required for analog signal chains or precision comparators | Select when system-level accuracy demands <±30 mV deviation at 13 V; higher cost than C-series |
| MMBZ5243BS | 13 V nominal, ±5 %, SOT-23 package, 100 mW Ptot, 25 Ω rdiff at 20 mA | Lower power rating and higher dynamic impedance limit use to sub-5 mA loads | Choose only for space-constrained designs where 100 mW dissipation suffices and SOT-23 pick-and-place is preferred |
Compared with BZT5250H-C13X, BZT5250H-B13 offers tighter regulation but higher unit cost, while MMBZ5243BS sacrifices power handling and impedance performance for smaller footprint-making the C13X optimal for balanced cost, stability, and thermal robustness in 13 V low-current systems.

FAQ
What is the maximum reverse voltage before breakdown for BZT5250H-C13X?
The BZT5250H-C13X exhibits a nominal Zener voltage of 13 V, with a guaranteed range of 12.35 V to 13.65 V at 5 mA test current. Breakdown begins gradually above ~11.5 V, but full regulation is only assured within the specified 12.35–13.65 V window under defined current and temperature conditions.
Can BZT5250H-C13X be used in place of a 12 V Zener diode?
No - BZT5250H-C13X is strictly a 13 V device (12.35–13.65 V range). Substituting it for a 12 V Zener would raise the regulated voltage by ≥0.35 V, potentially exceeding downstream IC absolute maximum ratings or altering comparator thresholds. Use BZT5250H-C12X (12 V, 11.4–12.6 V range) instead.
Is the SOD123F package compatible with standard reflow profiles?
Yes - Nexperia specifies reflow soldering as the only recommended method for SOD123F. The package supports JEDEC J-STD-020-compliant profiles, including peak temperatures up to 260 °C for ≤30 seconds, with thermal resistance data validated on FR4 PCBs using the footprint shown in Figure 10 of the datasheet.
Does BZT5250H-C13X have automotive qualification?
No - the BZT5250H-C13X is not automotive-qualified. The datasheet explicitly states "Non-automotive qualified products" and confirms no AEC-Q200 testing or automotive-specific reliability validation. For automotive applications, select Nexperia's AEC-Q200-qualified Zener series such as PZTA44 or BZX84-A13.
