Product details
Overview
BZT5250H-C2V7X from Nexperia is a low-current Zener diode in SOD123F package, designed for precision voltage regulation at 2.7 V nominal with ±5 % tolerance and specified at 50 µA test current. It delivers 830 mW total power dissipation, 190 pF capacitance at 0 V, and 1 µA reverse leakage at 2.0 V, enabling stable biasing in portable battery-powered circuits and low-power sensor interfaces.
For engineers reviewing the BZT5250H-C2V7X datasheet, BZT5250H-C2V7X pinout, BZT5250H-C2V7X application, or BZT5250H-C2V7X equivalent, this page provides verified Zener voltage, thermal resistance (150 K/W junction-to-solder point), differential resistance (≤600 Ω at 50 µA), cathode/anode polarity marking, and SOD123F footprint compatibility for PCB layout validation.
Technical Context
This Zener diode operates in reverse breakdown mode with a nominal 2.7 V regulation voltage, optimized for low-bias applications where minimal quiescent current is critical. Its intentional minor rise in leakage current improves switching speed and reduces noise per AN90031, distinguishing it from standard Zeners.
The device uses silicon planar technology in an SOD123F package with defined thermal resistance to solder point (150 K/W) and ambient (330 K/W), supporting reliable operation up to 150 °C junction temperature under controlled PCB mounting conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 2.565 V to 2.835 V at IZ = 50 µA - tight 5 % tolerance enables accurate low-current reference generation |
| Differential Resistance rdiff | ≤600 Ω at IZ = 50 µA - ensures stable regulation under light load variations |
| Reverse Current IR | 1 µA at VR = 2.0 V - ultra-low leakage preserves battery life in always-on circuits |
| Total Power Dissipation Ptot | 830 mW at Tamb ≤ 25 °C on 1 cm² cathode pad - supports moderate power handling without heatsinking |
| Diode Capacitance Cd | 190 pF at f = 1 MHz, VR = 0 V - low capacitance minimizes signal coupling in high-frequency bias networks |
| Forward Voltage VF | 0.9 V at IF = 10 mA - defines forward conduction threshold for protection or clamping use cases |
| Junction Temperature Tj | −55 °C to +150 °C - wide operating range suits industrial and automotive-adjacent environments |
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 for correct PCB orientation |
| 2 | Anode (A) | Connected to ground or lower-potential rail; forms reverse-biased junction for Zener operation |
Key Features
| Feature | Design Value |
|---|---|
| Low test current specification | Rated at 50 µA - enables accurate regulation in micro-power systems where bias current must be minimized |
| Optimized leakage profile | Intentional minor rise in IR per AN90031 - reduces switching transients and broadband noise in sensitive analog stages |
| Thermal performance | Rth(j-sp) = 150 K/W - allows direct thermal coupling to PCB copper for passive heat management without extra vias |
| Small-form-factor packaging | SOD123F footprint - occupies only 4.16 mm² board area, compatible with high-density portable designs |
| Two tolerance options | ±2 % (B-series) and ±5 % (C-series) - BZT5250H-C2V7X belongs to the cost-optimized ±5 % variant for non-critical references |
Applications
| Portable Sensor Biasing | Low-Power Microcontroller Reset Circuit |
|---|---|

Use Value: 1 µA leakage at 2.0 V prevents measurable drain on CR2032 cell, extending operational lifetime beyond 5 years. |
Use Scenario: Generating clean reset threshold for ultra-low-power MCU (e.g., STM32L0) during brown-out conditions. IC Role / Device Role / Timing Role: Functions as precision voltage detection element in RC-based reset generator, triggering reset below 2.565 V. Use Value: 600 Ω differential resistance ensures minimal voltage droop under 10 µA load, preserving reset accuracy across temperature. |
| USB-C Power Negotiation Interface | Industrial 4–20 mA Loop-Supply Reference |
|
Use Scenario: Clamping and regulating auxiliary 2.7 V supply for USB-C CC logic in embedded host controller. IC Role / Device Role / Timing Role: Zener serves dual role: voltage clamp during hot-plug transients and stable bias source for level-shifting circuitry. Use Value: 190 pF capacitance avoids signal integrity degradation on 300 kHz CC line while providing robust ESD immunity. |
Use Scenario: Establishing precise 2.7 V reference for DAC output stage in loop-powered field transmitter. IC Role / Device Role / Timing Role: Shunt regulator maintains fixed headroom above 2.0 V compliance voltage required by 4–20 mA driver ICs.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZT52-C2V7 | Same 2.7 V nominal, ±5 % tolerance, but rated at 500 mW Ptot and uses SOD123 (not SOD123F) package | Larger thermal resistance (Rth(j-a) ≈ 500 K/W) limits power handling on compact PCBs | Select when legacy SOD123 footprint compatibility is required and thermal margin is available |
| MMSZ5223B | 2.7 V, ±5 %, 500 mW, SOD123 package; higher rdiff (1000 Ω typical at 20 µA) and no optimized leakage profile | Noise-sensitive analog biasing may require additional filtering due to higher dynamic impedance | Choose for cost-sensitive consumer applications where fast switching and low noise are not critical |
Compared with BZT5250H-C2V7X, BZT52-C2V7 offers identical electrical specs but reduced thermal performance in a non-flat-lead package, while MMSZ5223B trades off regulation stability and noise behavior for broader distributor availability-making BZT5250H-C2V7X optimal for space-constrained, low-noise, battery-critical designs.

FAQ
What is the maximum reverse voltage that can be continuously applied to BZT5250H-C2V7X without breakdown?
The device is rated for continuous reverse voltage up to its nominal Zener voltage of 2.7 V (2.565–2.835 V range). Applying more than 2.835 V will cause sustained breakdown and power dissipation; absolute maximum reverse voltage is not specified beyond the Zener range, and operation above VZ max must remain within Ptot and thermal limits.
How does the "intentional minor rise of leakage current" affect circuit design?
This feature, documented in AN90031, slightly increases reverse current near knee voltage to reduce minority-carrier storage time-improving transient response and lowering broadband noise. Designers benefit from faster regulation settling and cleaner DC bias without adding external filtering, especially in op-amp reference or ADC input stages.
Can BZT5250H-C2V7X be used in forward conduction mode like a standard diode?
Yes: it exhibits 0.9 V forward voltage at 10 mA, matching typical silicon diode behavior. However, its primary design intent is reverse-bias Zener operation; forward use is limited to low-current clamping or indicator functions-not power rectification-due to 200 mA absolute maximum forward current rating.
Is the SOD123F package compatible with standard reflow soldering profiles?
Yes: Nexperia specifies reflow soldering as the only recommended method, with footprint dimensions published for standard stencil design (2× 1.2 mm solder lands, 1.1 mm paste deposits). The flat-lead geometry ensures coplanarity and reliable joint formation under IPC-J-STD-020-compliant peak temperatures up to 260 °C.
