Product details
Overview
BZT5250H-C3V6-Q from Nexperia is a low-current Zener diode in SOD123F package, designed for precision voltage regulation at 3.6 V nominal with ±5 % tolerance, 95 Ω differential resistance at 5 mA, and specified test current of 50 μA - enabling stable biasing in battery-powered sensor nodes and automotive microcontroller reset circuits.
For engineers reviewing the BZT5250H-C3V6-Q datasheet, BZT5250H-C3V6-Q pinout, BZT5250H-C3V6-Q application, or BZT5250H-C3V6-Q equivalent, this page delivers verified Zener voltage, thermal resistance (150 K/W junction-to-solder point), AEC-Q101 qualification status, and SOD123F footprint compatibility for production-grade automotive and portable electronics design.
Technical Context
This Zener diode operates as a two-terminal shunt voltage regulator, maintaining 3.6 V across its terminals under reverse-bias conditions with a specified test current of 50 μA and rated power dissipation up to 830 mW at 25 °C ambient. Its low leakage current profile is intentionally optimized per AN90031 for fast switching transients and reduced noise coupling in sensitive analog rails.
Thermal performance is defined by Rth(j-sp) = 150 K/W (junction-to-solder point) on FR4 PCB with tin-plated cathode pad, supporting reliable operation up to 150 °C junction temperature. The device exhibits a negative temperature coefficient of −3.5 mV/K, ensuring predictable drift behavior over automotive temperature ranges (−55 °C to +150 °C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 3.42 V to 3.78 V at IZ = 50 µA - ensures ±5 % regulation accuracy for low-power reference generation |
| Differential Resistance rdiff | 95 Ω at IZ = 5 mA - limits output impedance for stable regulation under small load variations |
| Forward Voltage VF | ≤ 0.9 V at IF = 10 mA - enables use as polarity protection or clamping diode in dual-role circuits |
| Total Power Dissipation Ptot | 830 mW at Tamb ≤ 25 °C - supports continuous operation in compact SMD layouts with minimal heatsinking |
| Junction Temperature Tj | −55 °C to +150 °C - qualified for under-hood automotive environments and industrial edge sensors |
| AEC-Q101 Qualified | Yes - certified for automotive discrete semiconductor stress testing, including HTRB, HTGB, and ESD |
| Package | SOD123F - 2.6 mm × 1.6 mm × 1.1 mm surface-mount plastic package with standardized FR4 footprint |
Pinout & Package
SOD123F is a 2-lead surface-mount plastic package with cathode marked by a bar on the body. Mounting requires reflow soldering only; footprint dimensions are 2.9 mm × 1.6 mm occupied area with 1.2 mm × 1.1 mm solder lands per terminal.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to regulated output node; marking bar identifies this terminal - critical for correct orientation during automated placement |
| 2 (A) | Anode | Connected to ground or lower-potential rail; forms reverse-biased junction enabling Zener breakdown at 3.6 V |
Key Features
| Feature | Design Value |
|---|---|
| Low-test-current specification | Rated at IZ = 50 µA - minimizes quiescent current draw in always-on battery circuits (e.g., telematics wake-up monitors) |
| Optimized leakage profile | Intentional minor rise per AN90031 - reduces switching noise in ADC reference rails and clock buffer supplies |
| AEC-Q101 qualification | Qualified for automotive applications - meets stress tests including high-temperature reverse bias (HTRB) and temperature cycling |
| Thermal resistance control | Rth(j-sp) = 150 K/W - enables predictable derating curves for PCB-level thermal management without external heatsinks |
| Standardized SOD123F footprint | Compatible with IPC-7351B Level B land pattern - ensures drop-in replacement capability across multiple Zener families |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZT52-C3V6,115 | Same SOD123 package but ±5 % tolerance, 100 Ω rdiff at 5 mA, no AEC-Q101 qualification | Not qualified for automotive; suitable for consumer-grade portable devices only | Select when cost sensitivity outweighs automotive reliability requirements |
| MMSZ5227BT1G | SOD-123 package, 3.6 V ±5 %, 150 Ω rdiff, 500 mW Ptot, AEC-Q101 qualified | Higher dynamic impedance degrades regulation under varying load; lower power rating limits thermal headroom | Choose only if legacy BOM mandates ON Semiconductor footprint compatibility |
Compared with BZT5250H-C3V6-Q, the BZT52-C3V6,115 lacks automotive qualification and has higher impedance, while MMSZ5227BT1G trades 330 mW lower power handling and 55 Ω higher rdiff for cross-platform sourcing - making the Nexperia part optimal for thermally constrained, safety-critical automotive regulation.

FAQ
What is the maximum reverse current (IR) at 3.0 V for BZT5250H-C3V6-Q?
At VR = 3.0 V and Tamb = 25 °C, the typical reverse current is 2.0 µA, with a maximum of 2.5 µA per Table 8. This low leakage ensures minimal standby power loss in always-on automotive modules such as door module wake-up circuits.
Can BZT5250H-C3V6-Q be used in place of a 3.3 V Zener diode?
No - its nominal Zener voltage is 3.6 V with a guaranteed range of 3.42 V to 3.78 V. Substituting it for a 3.3 V part would raise the regulation threshold by ≥0.12 V, potentially causing incorrect reset assertion or ADC reference error in systems calibrated for 3.3 V.
Is the SOD123F package compatible with standard SOD-123 reflow profiles?
Yes - the SOD123F outline matches IPC-7351B Level B for SOD-123, and Nexperia specifies reflow soldering as the only recommended method. Peak temperature must not exceed 260 °C for ≤ 30 seconds, matching JEDEC J-STD-020D.4 requirements.
Does BZT5250H-C3V6-Q support bidirectional ESD protection?
No - it is a unidirectional Zener diode optimized for reverse-bias regulation. While it clamps above 3.6 V in reverse, it conducts forward at ~0.9 V and offers no controlled clamping in forward direction; dedicated TVS diodes like PESD5V0S1BA should be used for bidirectional ESD suppression.
