Product details
Overview
BZT5250H-C2V4X from Nexperia is a low-current Zener diode in SOD123F package, providing 2.4 V ±5 % nominal regulation at 50 µA test current, with 600 Ω differential resistance and 2 µA reverse leakage at 1.0 V, designed for precision voltage reference and biasing in portable battery-powered systems.
For engineers reviewing the BZT5250H-C2V4X datasheet, BZT5250H-C2V4X pinout, BZT5250H-C2V4X application, or BZT5250H-C2V4X equivalent, this device serves as a stable, low-power shunt regulator where minimal quiescent current and predictable low-voltage Zener behavior are critical in space-constrained SMT designs.
Technical Context
This Zener diode operates in reverse breakdown mode with a specified working voltage of 2.28 V to 2.52 V at IZ = 50 µA, exhibiting a negative temperature coefficient of −3.5 mV/K and low capacitance (200 pF at 0 V) suitable for noise-sensitive analog references.
Its thermal resistance from junction to solder point is 70 K/W, enabling reliable operation up to 150 °C junction temperature, while its 830 mW total power dissipation rating applies under defined PCB mounting conditions (1 cm² cathode pad on FR4).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 2.28 V to 2.52 V at IZ = 50 µA - defines tight regulation window for low-voltage reference circuits |
| Differential Resistance (rdiff) | 600 Ω max at IZ = 50 µA - indicates moderate impedance stability under light load |
| Reverse Leakage (IR) | 2 µA max at VR = 1.0 V - ensures ultra-low standby current in battery-critical applications |
| Forward Voltage (VF) | 0.9 V max at IF = 10 mA - supports use as low-drop rectifier or clamp in dual-role layouts |
| Total Power Dissipation (Ptot) | 830 mW at Tamb ≤ 25 °C with 1 cm² cathode pad - sets thermal design boundary for PCB layout |
| Junction Temperature (Tj) | −55 °C to +150 °C - enables operation across industrial ambient ranges without derating |
Pinout & Package
The BZT5250H-C2V4X uses the SOD123F surface-mount plastic package (2.6 mm × 1.6 mm × 1.1 mm), featuring flat leads and a marking bar indicating the cathode terminal.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; polarity marker aligns with PCB silkscreen bar for automated assembly verification |
| 2 | Anode (A) | Connected to ground or lower-potential rail; forms shunt path for excess current during regulation |
Key Features
| Feature | Design Value |
|---|---|
| Low test current specification | Rated at 50 µA - enables stable regulation in micro-power sensor nodes and sleep-mode circuits |
| Optimized leakage profile | Intentional minor rise in leakage per AN90031 - improves switching speed and reduces noise in dynamic bias networks |
| Tolerance option | ±5 % (C-series) - balances cost and accuracy for non-critical reference functions |
| SMD-compatible footprint | SOD123F package with standard reflow footprint - supports high-volume automated placement and IPC-compliant soldering |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5222BS-7-F | 2.4 V ±5 %, SOD-323, 200 mW Ptot, 100 Ω rdiff at 20 mA | Higher test current (20 mA) and lower rdiff - suited for higher-load regulation but less optimal for µA-bias circuits | Select when load current exceeds 50 µA and tighter dynamic impedance is required |
| BZX384-C2V4 | 2.4 V ±5 %, SOD-323, 300 mW Ptot, 600 Ω rdiff at 5 mA | Higher test current (5 mA) and reduced thermal margin - limited to ambient-limited, low-duty-cycle use | Select only for cost-sensitive, non-continuous bias applications with adequate board cooling |
Compared with MMBZ5222BS-7-F and BZX384-C2V4, the BZT5250H-C2V4X uniquely supports stable 2.4 V regulation at 50 µA with 830 mW thermal headroom and SOD123F mechanical robustness-making it the sole choice for continuous, low-IQ, high-reliability portable reference designs.

FAQ
What is the maximum reverse voltage before breakdown for BZT5250H-C2V4X?
The BZT5250H-C2V4X exhibits a nominal Zener voltage of 2.4 V with guaranteed limits of 2.28 V (min) and 2.52 V (max) at IZ = 50 µA. It does not have a distinct "breakdown threshold" - instead, it enters controlled reverse conduction within this specified band, with gradual knee characteristics typical of low-voltage Zeners.
Can BZT5250H-C2V4X be used in forward conduction mode?
Yes - the device has a maximum forward voltage of 0.9 V at 10 mA, making it usable as a low-drop clamp or protection diode. However, its primary design intent and characterization are for reverse-biased Zener operation; forward parameters are secondary and not optimized for switching or rectification duty cycles.
How does the "C" suffix in BZT5250H-C2V4X affect tolerance and temperature behavior?
The "C" denotes ±5 % voltage tolerance at IZ = 50 µA and corresponds to the higher-leakage variant optimized per AN90031 for faster transient response and lower noise. Its temperature coefficient remains −3.5 mV/K, identical to "B"-series parts, ensuring consistent thermal drift behavior despite leakage differences.
Is thermal derating required above 25 °C ambient?
Yes - the 830 mW total power dissipation rating applies only at Tamb ≤ 25 °C with a 1 cm² cathode pad. Above that, linear derating applies at 8.3 mW/°C based on Rth(j-a) = 150 K/W, requiring explicit thermal modeling for operation above 65 °C ambient in sealed enclosures.
