Product details
Overview
BZT5250H-C2V2X from Nexperia is a low-current Zener diode in SOD123F package, rated for 2.2 V nominal regulation voltage at 50 µA test current, with ±5 % tolerance, 830 mW total power dissipation, and 600 Ω differential resistance at 50 µA - used for precision biasing and voltage reference in portable battery-powered sensor nodes.
For engineers reviewing the BZT5250H-C2V2X datasheet, BZT5250H-C2V2X pinout, BZT5250H-C2V2X application, or BZT5250H-C2V2X equivalent, this page delivers verified electrical parameters, thermal behavior under PCB mounting conditions, cathode/anode terminal mapping, and real-world substitution guidance for low-power analog signal conditioning designs.
Technical Context
This Zener operates in reverse breakdown mode with a specified 2.2 V nominal working voltage at IZ = 50 µA, exhibiting a temperature coefficient of –3.5 mV/K and 210 pF junction capacitance at 0 V. Its low test current enables stable regulation in micro-power circuits where quiescent current must remain below 100 µA.
The device features intentional leakage optimization per AN90031 for fast switching transients and reduced noise in feedback paths. Thermal resistance from junction to solder point is 70 K/W when mounted on FR4 with 1 cm² cathode pad, supporting reliable operation up to 150 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Zener Voltage | 2.2 V at IZ = 50 µA - defines precise low-current reference point for analog bias networks |
| Tolerance | ±5 % - supports cost-sensitive designs where tighter regulation is not required |
| Differential Resistance | 600 Ω at IZ = 50 µA - indicates moderate regulation stiffness suitable for non-critical references |
| Forward Voltage | 0.9 V at IF = 10 mA - enables predictable forward conduction during transient overvoltage clamping |
| Total Power Dissipation | 830 mW at Tamb ≤ 25 °C with 1 cm² cathode pad - sets maximum steady-state power handling under defined PCB layout |
| Junction Temperature Limit | 150 °C - constrains thermal design margin for continuous operation in enclosed environments |
| Reverse Current | 1.0 µA at VR = 1.0 V - quantifies leakage impact on ultra-low-power standby circuits |
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.

Key Features
| Feature | Design Value |
|---|---|
| Low test current operation | Specified at 50 µA - enables use in battery-powered systems with sub-100 µA supply budgets |
| Optimized leakage profile | Intentional minor rise per AN90031 - improves switching speed and reduces noise in feedback loops |
| Thermal performance | Rth(j-sp) = 70 K/W - allows accurate junction temperature estimation using solder point measurement |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZT52-C2V2 | Same 2.2 V nominal, ±5 % tolerance, but rated for 500 mW Ptot and uses SOD-123 package (not SOD123F) | Larger thermal resistance (Rth(j-a) ≈ 500 K/W vs. 330 K/W) limits power handling in compact layouts | Select when legacy footprint compatibility is required and thermal budget permits higher Rth |
| MMSZ5222B | 2.2 V nominal, ±5 %, 500 mW rating, SOD-123 package, 250 Ω rdiff at 20 mA - stiffer regulation but higher test current | Requires ≥20 mA test current for spec compliance, incompatible with µA-level bias networks | Choose only if circuit can support >10 µA minimum Zener current and tighter regulation is critical |
Compared with BZT5250H-C2V2X, BZT52-C2V2 offers identical voltage specs but reduced thermal performance due to non-flat-lead packaging, while MMSZ5222B trades low-current operation for improved regulation stiffness - making BZT5250H-C2V2X uniquely suited for sub-100 µA portable reference applications.

FAQ
What is the maximum reverse voltage before breakdown for BZT5250H-C2V2X?
The nominal Zener voltage is 2.2 V at 50 µA test current, with guaranteed minimum and maximum values of 2.09 V and 2.31 V respectively. Breakdown begins near the lower limit and stabilizes within this band; operation above 2.31 V risks exceeding specified differential resistance and temperature coefficient behavior.
Can BZT5250H-C2V2X be used in place of a standard 2.2 V Zener like 1N4728A?
No - the 1N4728A is rated for 3.0 W and requires 20 mA test current, whereas BZT5250H-C2V2X is optimized for 50 µA operation and 830 mW dissipation. Substituting it into a 20 mA circuit would cause excessive voltage deviation and thermal stress due to mismatched rdiff and power rating.
How does the SOD123F package differ electrically from standard SOD-123?
SOD123F features a flat lead profile that reduces thermal resistance to solder point (70 K/W vs. ~100 K/W for standard SOD-123), enabling higher power handling at same ambient temperature. It also improves coplanarity for fine-pitch reflow, but shares identical pinout and marking orientation with SOD-123.
Is BZT5250H-C2V2X suitable for automotive applications?
No - this device is not AEC-Q200 qualified and lacks automotive-grade screening, temperature cycling validation, or extended lifetime reliability testing. Nexperia explicitly states non-automotive qualification in the legal disclaimers; use only in industrial, consumer, or medical portable equipment.
