Product details
Overview
BZT5250H-C6V2X from Nexperia is a low-current Zener diode in SOD123F package, providing precise 6.2 V regulation at 50 µA test current with ±5 % tolerance, 160 Ω dynamic impedance at 5 mA, and optimized leakage for fast switching in portable power rails.
For engineers reviewing the BZT5250H-C6V2X datasheet, BZT5250H-C6V2X pinout, BZT5250H-C6V2X application, or BZT5250H-C6V2X equivalent, this device is selected for low-bias voltage reference, battery-powered sensor biasing, and precision clamping where thermal stability and minimal quiescent current matter.
Technical Context
This Zener operates in reverse breakdown with a nominal 6.2 V working voltage (5.89–6.51 V range), exhibiting a positive temperature coefficient of +0.4 mV/K - enabling stable regulation across ambient temperatures from –55 °C to +150 °C. Its low 50 µA test current supports ultra-low-power bias networks.
The device features intentional minor leakage current enhancement per AN90031 to reduce switching noise and improve transient response in signal conditioning paths, while maintaining 830 mW total power dissipation on a 1 cm² cathode pad per JEDEC-compliant FR4 layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.2 V nominal, 5.89–6.51 V min/max at IZ = 50 µA - defines tight regulation window for reference circuits |
| Tolerance | ±5 % - matches C-series marking (XG), suitable for non-critical but stable voltage clamping |
| Differential Resistance (rdiff) | 160 Ω max at IZ = 5 mA - ensures low output impedance under light load for clean reference stability |
| Temperature Coefficient (SZ) | +0.4 mV/K - enables predictable, low-drift behavior over industrial temperature range |
| Forward Voltage (VF) | 0.9 V max at IF = 10 mA - supports bidirectional protection or dual-use as clamp/rectifier |
| Total Power Dissipation (Ptot) | 830 mW at Tamb ≤ 25 °C with 1 cm² cathode pad - sets thermal derating baseline for PCB layout |
| Junction Temperature (Tj) | 150 °C max - defines absolute reliability limit for continuous operation |
Pinout & Package
SOD123F surface-mount plastic package: 2.6 mm × 1.6 mm × 1.1 mm body, flat lead profile, cathode marked by bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; marking bar identifies this terminal - critical for correct polarity in shunt regulator configuration |
| 2 | Anode (A) | Connected to ground or lower-potential rail; completes reverse-bias path for Zener conduction |
Key Features
| Feature | Design Value |
|---|---|
| Low test current operation | Specified at 50 µA - enables use in microamp-level bias networks without loading sensitive sources |
| Optimized leakage profile | Intentional minor rise per AN90031 - reduces switching noise and improves transient response in signal paths |
| Small-form-factor SMD | SOD123F footprint - saves board space in wearables, IoT nodes, and compact sensor modules |
| Two-tolerance series | ±2 % (B-series) and ±5 % (C-series) - allows cost/performance trade-off without redesigning layout |
Applications
| Portable Sensor Biasing | Low-Power Microcontroller Reset Clamping |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZT52-C6V2,115 | Same SOD123F package, ±5 % tolerance, but rated at 500 mW Ptot and higher rdiff (200 Ω) | Limited to lower-power clamping; less stable under varying load due to higher impedance | Select when legacy footprint compatibility is required and thermal margin is ample |
| MMSZ5234BT1G | SOD-123 package, ±5 %, 6.2 V, but specified at 20 mA test current and 100 Ω rdiff; no intentional leakage tuning | Better regulation under medium load, but higher bias current incompatible with µA-sleep modes | Select for higher-current reference designs where 20 mA test current is acceptable |
Compared with BZT52-C6V2,115, the BZT5250H-C6V2X offers 66 % higher power rating and lower impedance for improved regulation fidelity; versus MMSZ5234BT1G, it trades 15 µA extra test current for noise-optimized switching behavior in ultra-low-power systems.

FAQ
What is the maximum reverse current (IR) at 5.5 V for BZT5250H-C6V2X?
At 5.5 V reverse bias and Tj = 25 °C, the typical reverse current is <0.1 µA - confirmed in Figure 5 of the datasheet for the C6V2 variant. This ultra-low leakage ensures minimal loading on high-impedance bias networks and preserves battery life in always-on sensor nodes.
Can BZT5250H-C6V2X be used in place of a standard 6.2 V Zener like 1N4735A?
No - the BZT5250H-C6V2X is not a drop-in replacement for through-hole Zeners like 1N4735A. It is rated for 50 µA test current (vs. 41 mA for 1N4735A), has different thermal derating, and uses SOD123F packaging. Substitution requires verifying bias network compliance with low-current regulation and PCB layout adaptation.
Does the "X" in BZT5250H-C6V2X indicate a specific tape-and-reel quantity or packaging variant?
Yes - the "X" suffix denotes the standard 3,000-piece 8 mm tape-and-reel packaging per IEC 60286-3, compatible with automated SMT placement equipment. It does not indicate electrical or thermal differentiation from other C6V2 variants; all share identical electrical specs and SOD123F mechanical form.
How does the intentional leakage current enhancement affect long-term reliability?
The controlled leakage increase is implemented via process-level doping adjustments documented in AN90031 and does not compromise reliability. Accelerated life testing shows no degradation in VZ stability or failure rate beyond standard Nexperia Zener qualification limits (JESD22-A108, 1000 hrs at 150 °C).
