Product details
Overview
BZT5250H-C6V2-Q from Nexperia is a low-current Zener diode in SOD123F package, designed for precision voltage regulation at 6.2 V nominal with ±5 % tolerance, specified at 50 µA test current, and qualified to AEC-Q101 for automotive power rail clamping and biasing in battery-powered ECUs.
For engineers reviewing the BZT5250H-C6V2-Q datasheet, BZT5250H-C6V2-Q pinout, BZT5250H-C6V2-Q application, or BZT5250H-C6V2-Q equivalent, this part supports low-quiescent-current voltage reference design, reverse polarity protection circuits, and ESD-tolerant signal-level clamping where thermal stability and small footprint are critical.
Technical Context
This Zener diode operates as a two-terminal voltage regulator with cathode-anode polarity, delivering stable 6.2 V breakdown under reverse bias at IZ = 50 µA (typical), with differential resistance of 160 Ω at IZ = 5 mA and temperature coefficient of +0.4 mV/K - indicating positive drift over temperature.
Its construction uses silicon planar technology in an SOD123F package with 1 cm² cathode pad thermal layout, achieving Rth(j-sp) = 150 K/W and supporting up to 830 mW total power dissipation at Tamb ≤ 25 °C, while maintaining <1 µA reverse leakage at VR = 4.5 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.2 V nominal, ±5 % tolerance at IZ = 50 µA - enables accurate low-bias reference generation in space-constrained designs. |
| Differential Resistance (rdiff) | 160 Ω max at IZ = 5 mA - ensures minimal output voltage shift under load variation in regulation circuits. |
| Temperature Coefficient (SZ) | +0.4 mV/K - provides predictable positive VZ drift, simplifying thermal compensation in automotive ambient ranges. |
| Forward Voltage (VF) | 0.9 V max at IF = 10 mA - supports reliable forward conduction for polarity protection or OR-ing functions. |
| Total Power Dissipation (Ptot) | 830 mW at Tamb ≤ 25 °C on FR4 PCB with 1 cm² cathode pad - defines maximum steady-state thermal envelope for board-level layout. |
| Junction Temperature (Tj) | 150 °C max - sets upper thermal limit for operation in under-hood automotive environments. |
| AEC-Q101 Qualified | Yes - validated for automotive-grade reliability including HTOL, TC, HAST, and ESD per AEC stress test requirements. |
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 - must be routed to higher-potential rail in shunt regulation. |
| 2 | Anode (A) | Connected to ground or lower-potential reference; forms reverse-biased junction enabling Zener breakdown at 6.2 V. |
Key Features
| Feature | Design Value |
|---|---|
| Low test current specification | Rated at IZ = 50 µA - minimizes standby current draw in always-on automotive modules like CAN transceiver bias networks. |
| Optimized leakage profile | Intentional minor rise in IR for C-series - improves switching speed and reduces noise in transient suppression applications. |
| Automotive qualification | AEC-Q101 compliant - guarantees robustness against thermal cycling, humidity, and mechanical shock in engine control units. |
| Small-form-factor SMD | SOD123F footprint - occupies only 4.16 mm² PCB area, compatible with high-density routing in ADAS sensor nodes. |
Applications
| Engine Control Unit (ECU) Bias Network | Infotainment System Power Sequencing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZT52-C6V2,215 (Nexperia) | Same Zener voltage and SOD123 package but ±5 % tolerance and non-AEC-Q101 rated; Ptot = 500 mW. | Limited to industrial or consumer use; lacks automotive qualification and thermal derating margin. | Select when cost sensitivity outweighs automotive compliance and thermal headroom is sufficient. |
| MMSZ5234B-7-F (Diodes Inc.) | 6.2 V ±5 %, SOD-123, 500 mW Ptot, rdiff = 130 Ω at 20 mA - tighter dynamic impedance but lower power rating. | Not AEC-Q101 qualified; optimized for general-purpose portable electronics rather than under-hood environments. | Prefer for space-constrained consumer wearables where 500 mW suffices and automotive qualification is unnecessary. |
Compared with BZT52-C6V2,215 and MMSZ5234B-7-F, the BZT5250H-C6V2-Q delivers higher power handling (830 mW vs. 500 mW), AEC-Q101 validation, and intentional low-leakage optimization - making it uniquely suitable for thermally demanding, safety-critical automotive voltage reference roles.

FAQ
What is the maximum reverse voltage before breakdown for BZT5250H-C6V2-Q?
The nominal Zener voltage is 6.2 V with ±5 % tolerance, meaning guaranteed breakdown occurs between 5.89 V and 6.51 V at IZ = 50 µA. The device exhibits soft knee characteristics below 5.89 V, with reverse current remaining <1 µA at 4.5 V per datasheet Figure 5.
Can BZT5250H-C6V2-Q be used in parallel for higher power handling?
No - Zener diodes exhibit negative temperature coefficients at low currents and positive above knee current, causing thermal runaway when paralleled. For >830 mW dissipation, use a single higher-rated device or active regulation instead of parallel Zeners.
Is the SOD123F package compatible with standard reflow profiles?
Yes - Nexperia specifies reflow soldering as the only recommended method, with footprint dimensions provided in Figure 10. The package supports JEDEC J-STD-020 moisture sensitivity level 1 and withstands peak temperatures up to 260 °C for ≤60 seconds.
How does the "C" suffix in BZT5250H-C6V2-Q affect performance versus "B" variants?
The "C" suffix denotes ±5 % tolerance and intentional minor leakage current increase, optimizing fast switching response and noise reduction per AN90031. In contrast, "B" variants offer ±2 % tolerance and lower leakage - suited for precision reference but slower transient response.
